CLL & COVID 19: What Do Patients Need to Know?

 

How Can CLL Patients Take Advantage of Telemedicine?

Transcript:

Dr. Steven Coutre:

In terms of testing for CLL, additional testing, of course, diagnostically, it’s generally not a challenge. It’s very straight-forward. A test that we call Flow Cytometry on a blood sample is usually sufficient to establish the diagnosis. Very, very uncommonly would a bone marrow exam be needed, for example. And in routine practice, also, we don’t necessarily give CT scans to establish a diagnosis or even to, as people say, stage the disease. It really isn’t necessary in most cases.

However, we do have a staging system that correlates with the extent of the disease and that’s simply based on our exam and blood counts, but people also want more information. They wanna know how they’re gonna do, specifically. So, we can add additional tests, genetic testing as people often call it, that can further subdivide individuals into groups that give you additional information on how you might do, meaning if you’re without symptoms, and an observation is recommended, you wanna know, “Well, how long is it gonna be before I need treatment?” Although our staging system gives that information, we can refine that further.

One test is the so-called FISH test, which looks at specific chromosome abnormalities, and the second test that’s generally used is called the IGHV Mutation Assay. That’s really looking at what’s called the mutational status of your immunoglobulin genes. So, it’s really those two broad categories that are most relevant.

Now, we don’t necessarily advocate doing that testing on everyone at the time of diagnosis. Certainly, not everyone who is without symptoms, where we’ve already decided that treatment is not indicated. So, as you can imagine, you can do that testing. You might come up with a profile that’s less favorable. And then, instead of the watch and wait approach, or as folks like to call it, “watch and worry approach,” you worry even more. But then, of course, if you have a favorable profile, then you’re happier. You’re more pleased.

However, we don’t do anything differently regardless of what those tests show, at least at current state. Compared to a decision that’s already been made about treat or not treat. We do, however, strongly advocate getting that testing at the time of treatment, and sometimes, repeating some of the testing with subsequent treatment, when you require treatment, say, a second time, in some cases. So, very important to have a discussion about these tests and what information you will get from them.

Well, we’ll often see patients who are coming for another opinion about their disease. Perhaps they’ve been recently diagnosed, and they have been advised for observation, so, it’s, of course, natural to ask whether that’s a reasonable approach. And in that context, other testing often comes up in the conversation. Perhaps they had the testing done, the FISH, and the mutational testing, and they wanna know what it means, or actually we see some results that have been obtained and we ask them about it. And there’s very often confusion, or really lack of information about what they mean.

So, we really try to discuss that issue. That issue of testing with each and every patient, whether or not they’ve had it done, really trying to let them know what it means. That way they’re fully informed, and in some cases, people feel very strongly that they would like to have it done, even through they realize that we’re not gonna act on it at that point. So, I think pretty much for all patients, it should be part of the initial discussion.

Again, in terms of genetic testing are these tests that I discussed. It’s important to understand what information they give you so you understand why your physician may be making a distinction between one therapy versus another. It is very, very important to get that testing, if somebody is talking about using chemotherapy, for example, hopefully. That’s quite uncommon. But with our newer agents, we know that they work broadly despite those other features.

Nevertheless, I think it’s important for a patient to at least expect the discussion about these tests. We’re not asking you to go to your physician and ask that they be done in all cases, but really understand perhaps why your physician recommended that they not be done at that particular time.

What Do Genetic Tests Reveal About My CLL Treatment Options?


Transcript:

Dr. Philip Thompson:

I would say that I see a lot of patients that have previously seen an oncologist closer to home and then traveled to MD Anderson for a second opinion. And so, I can say that over the last three or four years, there’s definitely a significant change in the awareness of physicians in general about doing genetic testing for CLL.

So, in particular, almost everybody will get a FISH test, which I didn’t always see three or four years ago. And more patients are now having IGHV mutation status analysis done. The thing that I see that is very rarely done, though, is what we call next-generation sequencing, or NGS, that looks for mutations in individual genes, and most importantly, in the TP-53 gene that I mentioned.

So, I would – and the other thing that often isn’t done is what we call a carrier tag, which is a routine analysis of the chromosomes of the CLL cells. And it requires some special techniques for the lab to get it to work in CLL. But that can actually provide additional information compared to just FISH.

So, I would suggest to a patient, particularly if they’re gonna do a bone marrow biopsy on you, which is an invasive procedure, that you really try to get some clarity around what tests are going to be ordered on that beforehand. And if you’ve just been diagnosed and you’ve got early-stage CLL, you can make an argument about how many of these tests are absolutely necessary to start with. Because the biggest utility in these tests is in determining what type of treatment you’re going to have.

If you’re not immediately going to have treatment, they don’t necessarily change what your oncologist is going to do. They’re going to monitor you over time and see if your disease is getting worse or not. But I still think they’re useful to have the – a lot of them are useful, particularly the IGHV mutation status and FISH are useful to have at initial diagnosis. Because they give you a really good idea of what the biology of this disease is – this patient’s disease is like and how quickly they’re likely to progress, and that may change how frequently you monitor the patient.

But anyway, I would say it’s important to ask them what genetic testing you are gonna get. And that you ask – have an understanding of what can be ordered.

 And in particular, if you’re going to get treatment, you must ask for TP-53 sequencing, FISH for 17-P deletion, and IGHV mutation status because those three things are essential to determine the optimal treatment that you have. And you shouldn’t feel shy about asking, are those things going to be done.

CLL & COVID 19: What Do Patients Need to Know?

 

How to Learn More About Your CLL


Transcript:

Dr. Philip Thompson:

So, there are three main things we look at before initiating treatment in a patient.

One is what we call the IGHV mutational status of the patient. And this basically splits people into types of CLL. So-called mutated or unmutated. And this is a relatively complex concept. Basically, what happens in normal B-lymphocyte development, so B-lymphocytes are part of your immune system. Their job is they have a probe on the surface of the cell that looks for invading microorganisms. And when they find an invader, this probe binds to the organism. And then the cell actually undergoes, as part of its normal development, a process of mutation so that it makes the best possible antibody to fight that infection. So that’s a normal process that the B-lymphocyte undergoes when fighting infections.

So, CLL can arise from what we call a mature antigen-experienced mutated B-cell, or it can arise from a naive B-cell that has never gone through that process, in which case, it will have an unmutated IGHV. Now, it’s kind of counterintuitive, but the patients with a mutated IGHV generally have better outcomes. That type of CLL is less proliferative, it doesn’t grow as fast, and it also tends to respond better to certain types of treatment. Particularly, it responds better to chemotherapy than patients with unmutated IGHV.

However, the difference between those two is less important if you’re getting some of the newer therapies. Particularly, it seems like if you receive BTK inhibitors, it doesn’t really matter if you have mutated or unmutated IGHV, patients are responding very well. But I like to know whether they have a mutated or unmutated IGHV because it’s helpful for giving the patient an expectation of how their disease is likely to behave biologically.

But also, if they have a mutated they may be a candidate for chemotherapy-based treatment. Whereas if they have unmutated IGHV, I don’t use chemotherapy for those patients.

 

The second thing is a test called FISH. And FISH looks for chromosome abnormalities. So, we have 46 chromosomes, 23 from our mother and 23 from our father. They contain all of our genetic information. And in malignant diseases, you can have major abnormalities in the chromosomes of the cancer cells. Not in the rest of your body, just in the cancer cells. And they happen because of errors that are made when the cells are replicating their chromosomes.                                                                 

So, in CLL, there are four common abnormalities that we look for in a test called FISH, and they tell us a lot about the patient’s prognosis. And there’s one in particular that we look at that has a major impact on our decision making, and that’s a deletion on Chromosome 17.

So, a missing piece of Chromosome 17. And the reason that that’s important is it tends to be an aggressive form of CLL. It also does not respond to chemotherapy, or if it does, the responses are very, very short-lived. So basically, that’s a contrary indication to receiving chemotherapy for your CLL when you should receive another form of therapy if you have a 17-P deletion.

And then, finally, we look at a type of – we look for individual gene mutations in the cells. And that’s different from IGHV mutational status, although the names are kind of similar.

So, in CLL, there are numerous genes that can be affected by mutations that alter the function of the gene. In some cases, it makes the gene non-functional; in some cases, it changes the function in some way that perturbs the normal functioning of the cell and contributes to the malignant transformation of that cell.

So, the most important one, again, relates to a gene called TP-53. So that’s the gene that is deleted if you lose a piece of Chromosome 17. It’s located on the P arm of chromosome 17. If you mutate that gene, it has the same consequences essentially for the cell as if you delete it by deleting a piece of the chromosome. And the two often go together, so you’ll have a 17-P deletion and a mutation of the TP-53 gene on your other Chromosome 17. Because remember, you have two chromosome 17s. So, if you lose both, it may be even worse than only having one. However, it does seem that if you only have a mutation on the TP-53 gene, but you don’t have a deletion on Chromosome 17, that the responses of those patients to chemoimmunotherapy are still really poor.

So, it’s very important to find out, do you have a TP-53 mutation as well as do you have a deletion on Chromosome 17 before you embark on treatment, particularly if that treatment is going to be chemotherapy. So, those are the three things that we look for before    we start any patient on therapy.

Dr. Wakelee:

So, there’s so much happening in lung cancer research now, it is hard to really narrow it down to one thing to be specifically excited about. Where we have made so much progress in particular is with target treatments, and also with immune therapy. So, when we think about the targeted treatments, it’s only been about 15 years since we first learned about drugs that would specifically target the EGFR gene mutations.

And when we found a tumor with an EGFR gene mutation, we then had a medication we could give that would work better than chemo. And now we have five EGFR drugs available in the US. And then we found out about this ALK gene mutation that happen in some tumors. Now we have five drugs that work there. And the with ROS1, that was found, and now we’ve got four drugs that work there that are approved.

And it seems that we keep learning about more and more mutations, so those are mutations called NTRK and BRAF. And with all of those, we now have drug treatments, so it’s been very, very rapid discovery of specific gene mutations and drugs that work for that. And I think we’re continuing to see new targets being identified and new drugs being found.

And also, when those drugs stop working, better understanding why and what we can do to help them work longer, or what we can give next. So, that’s a very active area of research that’s exciting. And then we have the immune therapy. So, the ones that are available so far are drugs that block either PD-1 or PD-L1, and that's one of the really important stop signals for the immune system.

And tumors can use that stop signal to block an immune reaction to a tumor. But if you block that stop signal then the immune system can attack the cancer. So, that's really important, these PD-1, PD-L1 drugs.

We also know about another stop signal called CTLA-4, and there’re drugs that block that as well. And now, where there’s a ton of research is in trying to work with other parts of the immune system, other either pro-immune or anti-immune signals, and changing those in a way where we can improve the ability of the immune system to find the cancer cells and attack the cancer cells.

So, there are many, many studies being done with drugs, and especially in combinations, trying to get that response against the cancer from the immune system to be even stronger. And that’s, I think, where we’re making the most exciting headway now.

Critical Questions to Ask Your Lung Cancer Doctor

Dr. Wakelee:

So, the treatment of lung cancer has been changing very, very quickly. We’ve had a lot of new options that have become available in the last few years, and there’re new ones coming along all the time. When I started treating lung cancer, which was a number of years ago, we were able to treat and help people.

But our only real option when the cancer was metastatic was chemotherapy. Chemotherapy is still an important part of treatment for many people, but now we have other options. So, starting about 15 years ago, people were able to identify that some tumors had specific genetic changes. We also call these molecular changes, or gene mutations, or just mutations in the tumor. They have a lot of different names.

But when we do find them, these are things like EGFR or ALK or ROS or BRAF or MET, we actually have different treatment options that only work for tumors that have those specific genetic changes, and don’t work in tumors that don’t have those. So, when we talk about genetic changes a lot of people think, “Oh, that’s something that I’ve inherited.”

These are not things that are inherited. This is not something that’s in the whole person. It’s just in the tumor. So, it’s a mutation that happened in the DNA of the cell, and that cell then became the cancer. And depending on what that mutation or mutations are, we still can have chemotherapy, and that can work.

But for specific ones, and specifically EGFR, ALK, ROS, BRAF, we know that there are pill drugs and oral medication that actually is gonna be better than chemo, at least for a period of time, if a cancer has that specific mutation.

So, it’s really, really important to figure that out. It’s not something a doctor can sort out just by looking at the patient or looking at the tumor under the microscope. We have to do special testing, looking at the tumor DNA.

And we now have ways of looking for those mutations, not just in the tumor tissue, but also sometimes with blood. So, we can draw a blood test and look for those as well when there’s a tumor that’s shedding the DNA. So, it’s really important to think about that. And we now have a whole host of medications that we can offer people when we the find these mutations that we didn’t used to have, even a few years ago.

And, actually, if you think back over the last five years, we’ve had new drugs approved, a few of them every year, for these specific gene mutation tumors, so that’s really, really exciting. The other thing that’s changed dramatically just in the last five years is what we call immune therapy.

So, when we think about the different types of treatment, chemotherapy works by poisoning DNA. And in order to make a new cell, you have to make new DNA. Tumors are doing that more than a lot of normal tissue, and so we’re able to give chemotherapy and specifically hurt tumors and not the rest of the person very much.

With the targeted treatments where we find a gene target and where there’s a gene mutation in a tumor, those are medications that specifically hit that altered gene, that altered protein made by the gene. And then they work really, really well. What immune therapy does is it actually changes the way your body’s own immune system interacts with the tumor. So, we have a lot of types of immune cells, but the ones that are involved in really fighting the cancer directly are called T cells.

And so, normally, a T cell would recognize something that’s foreign like an abnormal-looking cell that’s a cancer, and attack it. But we have a lot of different systems in our body that stop the T cells from recognizing normal tissue and attacking it.

And one of the best systems for that is something called PD-1 and PD-L1. And so, if you have a T cell and it sees a PD-L1 signal on tissue, it assumes that that tissue was normal tissue and it doesn’t attack. But if you can hide that PD-L1 signal, then if it’s a T cell, a part of the immune system comes in and doesn’t see the PD-L1, it doesn’t get the stop signal. It’s not told to not attack. So, it could attack the tumor better.

And I’m not describing it well because it’s so complicated. There are a lot of different factors that help a T cell know whether to attack or not to attack. But, again, one of these key stop signals is the PD-1, PD-L1 interaction. And so, scientists were able to develop medications that can block PD-1 or PD-L1. And when those medications are in the body, if a tumor is using that particular stop signal as a way to hide from the immune system, when you give the medication that blocks it then the tumor is no longer hiding.

And then the immune system, those T cells, can come in and attack. So, these immune treatments, and there are now a lot, and so these are drugs, like pembrolizumab, also called Keytruda; nivolumab, which also called Opdivo; durvalumab, which is called IMFINZI. And there are many, many others. Those medications have now been shown to really, really help to fight cancer, particularly when the tumor is using that PD-L1 signal. But they can also be combined with chemotherapy and then they work even if there’s not a lot of PD-L1 in the tumor. So, again, it’s a very complex story.

But where we’ve seen dramatic improvements in treatment is we have targeted treatments when the genes are – there are specific genes mutating in tumors. We have immune therapy, which worked for a lot of other people. And sometimes when there’s also gene mutation, but not always, we still have chemotherapy. And then there’s ongoing research with a lot of different medications. Many of them are focusing on better ways to get the immune system to work against cancers beyond what we can already do.

Transcript:

Dr. Wakelee:

So, as a patient living with lung cancer, you have many options today that you wouldn’t have had 5, 10, 15 years ago, which is wonderful.

Because things are changing so quickly, it’s very hard for physicians and other care providers to keep up with all of the latest information. It’s especially hard if you are seeing an oncologist who not only has to keep up with everything that’s happening in lung cancer, but also everything that’s happening in breast cancer, and colon cancer, and melanoma, and so many other diseases.

And so, while everybody does their best to know the latest and greatest in research, and all of the new drug approvals, sometime that’s just possible. So, as a patient, you wanna make sure that you, focused on your particular disease, are up-to-date on what you can possibly know about the best ways to treat your disease, so you can talk to your physician and make sure that he or she also knows about those, and is using that latest information to help you get the best possible care.

There’s also a lot of ongoing clinical trials. And being able to ask about those and know what may or may not make sense for you, is also a reasonable thing to be able to talk with your doctor about.

And sometimes that involves continuing your care with your doctor, but also getting another opinion, particularly at a research center where they might have access to more trials, new drugs, some of which might be better than what’s available, and some of which might not be. But without talking to people about that, you’re not gonna be able to know that.

And that’s why it’s really important to do what you can or your family can do to be educated and know what is going on in the field of lung cancer, so you can get the best possible care.

Critical Questions to Ask Your Lung Cancer Doctor

Could Advances in Lung Cancer Research Benefit You?


Transcript:

Dr. Wakelee:

So, when facing a new diagnosis of lung cancer, one of the questions that often comes up is whether one should go get a second opinion or see a lung cancer specialist. And that is a question that obviously is gonna vary quite a bit by where a person is, where they’re getting seen, and what they’re facing.

I think a time that it’s really critical would be if someone has a Stage III lung cancer or told it might be Stage III. That’s a really good time to get a second opinion and make sure that the group that is taking care of you has had a multidisciplinary discussion. And when I say multidisciplinary, I mean, a thoracic surgeon, a radiation oncologist, and a medical oncologist have altogether looked at what’s going on with the particular case of that patient to decide up front what’s gonna be the best approach.

Because sometimes surgery is the right first approach. And sometimes it’s not. And sometimes radiation’s important, and sometimes it’s not.

So, it’s really critical to have a big team looking at what’s going on for Stage III. And if you’re in a hospital that really doesn’t see a lot of Stages III lung cancer that might be a good time to think about getting a second opinion outside of where you’re being treated.

I think, otherwise, if someone is newly diagnosed and we know the cancer is early stage where surgery might be involved, it’s good to check in that the surgeons who would be doing your operation are surgeons who know about lung cancer and have done lung cancer surgeries frequently. Sometimes in smaller hospitals there are surgeons who do both heart and lung surgery. And we know that the outcomes are not always quite as good in that setting.

Sometimes there’s no choice, and that’s okay. But if there is an opportunity to talk to a dedicated thoracic surgeon who’s used to doing lung cancer surgery, that’s another good time to get a second opinion. When we’re dealing with a more advanced stage of metastatic lung cancer, if someone is newly diagnosed and their tumor ends up having an unusual gene mutation or translocation.

And the molecular changes in lung cancer are really important to know about. And things like EGFR and ALK and RAS, where most medical oncologists will be familiar. But there’re others, like BRAF and RET and MET, and those can really change treatment outcomes as well, but not everybody who sees lots of different kinds of cancer as an oncologist will know everything there is to know about those.

So, if you have an unusual gene mutation, that’s another good time to get a second opinion with someone who’s a dedicated lung cancer expert. And usually those folks are at the larger academic medical centers, so oftentimes in cities, or affiliated with universities.

Another time is if someone does have a tumor with an EGFR, ALK, or one of the more common mutations, but the main drugs have stopped working, that’s often a time where someone who has specialized just in lung cancer might have some other options.

It’s also something to think through when someone’s newly diagnosed, if they know that their doctor has looked at the immune markers like PD-L1, and looked at the genetic changes in the tumor, and has a clear plan that’s gonna involve chemotherapy, or chemotherapy plus radiation, or chemotherapy plus immune therapy.

Then there might not be something that’s gonna be different in an academic center. But before you start treatment, if you’re still feeling okay, don’t have to start treatment tomorrow, and wanna know maybe that there’re clinical trial options, that’s another time to think about getting a second opinion. And a lot of academic centers will work to get people in very, very quickly if they knew they’ve just been diagnosed and they really need to get started on treatment right away.

Transcript:

Dr. Wakelee:

For a patient who is facing a new diagnosis of lung cancer, there are a lot of really important things to keep in mind. But really thinking about top three of them, the first one is that you wanna know what stage the cancer is. And when we talk about stage, we’re talking about how far the caner has spread. So, sometimes a cancer is found at Stage I when it’s still just a mass, a tumor in the lung.

Stage II means that it’s spread into some of the lymph nodes that are still in the lung. And for Stage I and II, for most people, we know that that means surgery is the treatment option. The next stage is Stage III, and that means that the cancer has started to spread into these lymph nodes.

And lymph nodes are just normal part of the body, but it’s a place cancer often will go. And if it goes into the lymph nodes in the center of the chest, called the mediastinum, then it becomes Stage III. And that changes the treatment. It’s usually more complicated. You wouldn’t normally just have surgery. There’s still sometimes surgery, and sometimes radiation, and almost always some sort of treatment like chemotherapy.

But it’s very complex. And usually we recommend that if you know it’s Stage III that you have a team that’s surgeons and radiation oncologists and medical oncologists to think about it. And then Stage IV means that’s it’s spread. So, knowing – meaning that it’s spread in a way where treatments are gonna involve chemotherapy or targeted treatment or immune therapy, and sometimes radiation, but not normally surgery.

And so, because it’s such a big difference in how things are treated based on stage, that’s the most important question to talk to your treating team about. The next most important question, assuming that it’s metastatic or Stage IV because that’s the most common way that we find lung cancer.

If it is metastatic or Stage IV then you wanna find out well, are there any markers, any tumor markers or cancer genetic changes, that are gonna help pick the treatment. And when I say that, I’m talking about gene changes in specific genes. The ones we think about a lot is something called EGFR, or epidermal growth factor receptor; or ALK, which is A-L-K; KRAS. There’s a whole list of them. But the most important are EGFR, ALK, and ROS, and BRAF.

And why that’s so critical is that if you have metastatic cancer and the tumor has one of those mutations then instead of chemotherapy, the best treatments are gonna be pill drugs, so basically, medications that you take my mouth. And we know that when the tumor has one of those specific mutations, the pill drugs are gonna be more likely to shrink the tumor and have that last longer. So, that’s why it’s so important to know about that. And then the other thing that we look at a lot is something called PD-L1, and that helps us determine about the immune therapy.

So, there’s been a lot on the news about this new class of treatments called immune therapy. And those can work for a lot of different people with a lot of different kinds of cancers. But they don’t always work. And this PD-L1 test can help us know a little bit more about when it might be the best choice, or when it might be something we can add to chemotherapy. And so, getting that information back is important, too.

And I’m gonna add a little bit extra to that. A lot of times that PD-L1 result will come back faster than the gene changes of the tumor, the molecular changes to the tumor. And it’s important to have the whole picture, so you wanna know not just what stage, not just the PD-L1, but also if there are any gene changes in the tumor, so that the best treatment choice can be talked about with the care team.

Patricia:

Here’s the last one that I have on my list here. Clinical trials are experimental and risky.

Dr. Edelman:

Yeah. Well, so is the rest of life. So, there generally – is there risk? Yes. Essentially, every patient is always a trial because we for the most part don’t – even in the disease states where we have very active treatment – so, let’s say – for example, we were talking about the EGFR mutation. So, we have excellent drugs. We have a drug now, osimertinib – outstanding drug, easy to take, low risk of side effects.

The earlier generations – there was a lot of rash, diarrhea. That’s been pretty much done away with. But on average, patients benefit from this drug for about a year and a half.

So, that’s not great if you’re 40 or 50 years old. You want to do better. So, what are our current studies? Well, we’re looking – we’re re-addressing a question that we thought had been answered, but really it wasn’t – about, well, what’s the value of chemotherapy plus this drug? What about the value of other drugs?

So, we can’t promise anybody anything, but our current treatments are still not good enough. There are certain diseases, let’s say Hodgkin’s disease, where you know you’re gonna cure almost all the patients up front or testicular cancer, etcetera, where – again, but thanks to trials, clinical trials, we now are at that stage. We’re not there yet in lung cancer, and the reality is is every patient should really be on a study. I think it’s – and we have this problem now in that our studies have also become far more complicated to enter people in because there are many more variables one has to look at it. What’s the molecular background of the tumor? How many prior therapies?

The condition of the patient, their organ function, etcetera – and the regulatory burden has become much, much greater. But clinical patients are in clinical trials. Let’s look at the question. Are they risky? Well, everything is risky, but we do a lot to manage that risk. Patients who are in studies are observed more closely. We have to. It’s the law. There’s frequently additional personnel assigned. They’re usually getting standard of care plus a new treatment or a new treatment followed by the standard of care or some variation of that.

They’re observed, like I said, much more carefully than we would otherwise. And so, I think actually patients on trials generally will do better, and we actually have evidence. Multiple individuals have looked at this – everything from first-in-man trials or early dose escalation studies, controlled studies – that show that patients, even those on the control arm, generally do better than similar types of patients who are not treated on studies because we just are more careful.

And the physician who participates in trials is generally someone who has a greater knowledge of the disease.

Is Lung Cancer Treatment Effective in Older Patients?


Transcript:

Patricia:

Let’s talk a little bit about some of the concerns that patients have about the side effects. Let’s see: Side effects are unavoidable.

Dr. Edelman:

Well, that’s not true. As I said, what were the side effects? If you go back a couple decades and you ask patients what were they concerned about, many of them were concerned about nausea and vomiting. And that is largely a thing of the past. Many patients will still have some queasiness with treatment, but even our most nausea-producing drugs – we really do have outstanding drugs for the prevention of that. You have to use them. You have to take them.

It’s very important to give them appropriately. There are very excellent guidelines that are out there. Sometimes, patients are still undertreated, no question about that. Not every drug has industry strong backing. There’s one drug – for example, olanzapine, (Zyprexa) was actually developed as an antipsychotic, and I always tell the patients, “No, I don’t think you’re crazy.”

But it’s at a lower dose, and we have excellent, excellent evidence that that drug given for a few evenings after chemotherapy is extraordinarily effective along with the other drugs in preventing nausea and vomiting. So, that’s one thing.

Hair loss is still somewhat inevitable with certain drugs – the taxanes. But many of our regimens don’t cause hair loss.

Or as I tell folks – only you and your hairdresser will know for sure because its hair on the pillow, but the average person won’t pick you out of a crowd. Those are big concerns still. There still are potentially life-threatening effects from chemotherapy, and we spend a lot of time educating people about that. But those are not inevitable, and it’s actually a minority of patients in lung cancer.

One should not confuse – there are different malignancies. Still, the treatments for say leukemia, though even that’s changing, can be extraordinarily toxic or the bone marrow transplant patients. Many, not just lung cancer, but in the other diseases as well – many of the things that people attribute to the drugs are more due to the disease. So, I always say, “The greatest failure and side effects to the drugs are they don’t work well enough because the side effects of the disease can be considerable.” So, that’s the bigger issue. The immunotherapeutic drugs have a rather interesting set of side effects.

They are clearly initially or frequently better tolerated than the older cytotoxics, which still have an extremely valuable place in the treatment and cure of lung cancer. The immunotherapeutics have clearly been quite beneficial, but their side effects can be subtle and far less predictable and can be very severe. Virtually, any organ in the body can be affected by this. We like to say, “If it ends in ‘itis,’ you can get it from immunotherapeutics.”

So, there are lots of side effects, no question. But they can be managed. They can be prevented. They can be treated. Sometimes, we have to abandon a drug. So, people who get severe – what we call immunotherapy-related adverse events – may not be able to continue on their drugs. But even that is not necessarily always the case.

Patricia:

This next one really gets to the heart of the doctor-patient relationship. I shouldn’t share my side effects with my healthcare team because I don’t want them to stop my treatment routine.

Dr. Edelman:

Well, you can’t prevent the side effects if you don’t know about them. And I always would tell patients, I said, “You know, if you’re having a problem, please don’t call me at 4:00 on Friday afternoon. I’m gonna end up sending you to the emergency room, which I may anyway.” But a lot of times, we can solve certain things over the phone. There are a lot of side effects that can be treated and particularly if one is aware early on. So, yeah, you should share the side effects because how’s somebody gonna know how to deal with them?

Now, the problem we run into sometimes is in a population that’s on average 60s and 70s, could be younger. There’re lots of things that can be just part of ordinary life. Everybody gets headaches, back pain, etcetera, etcetera.

We have to treat those sometimes and evaluate them much more aggressively because of the possibility of them being related to disease or drug, but it helps to sort it out. You can’t be too blasé about it because sometimes things need to be looked at very urgently, particularly with immunotherapeutic drugs. Some of the side effects that can be severe can sometimes be very subtle in their onset.

The Truth About Managing Lung Cancer Treatment Side Effects


Transcript:

Patricia:

Let’s talk a little bit about health literacy. What would you suggest patients use for online resources? What are good resources?

Dr. Edelman:

So, there are some excellent resources. The International Association for the Study of Lung Cancer has resources for patients. The National Coalition of Comprehensive Cancer Center Network (NCCN) has resources. American Society of Clinical Oncology has resources. So, those or American Cancer Society. So, there are some really reliable sources out there. And there’s a great deal that’s very unreliable – people’s Facebook pages. I’ve seen this.

Patricia:

It’s a big place.

Dr. Edelman:

Everybody always – and I think it’s important for people to understand. There will be people who will get something and have a fantastic response. I’ve used anecdotes.

The anecdotes I’ve used are to illustrate the potential hope of benefit. They’re not exceptions to the rule anymore. They’re the good case scenarios. I could have just as many anecdotes of people who didn’t benefit and stuff. And I think it is important going into this – and that’s why we are reassessing patients constantly and getting repeat scans because we don’t necessarily know always – even if something’s 90 percent effective, it means 10 percent of the time it’s not.

And each patient – we’re getting better at individualizing and personalizing therapy, but we’re not perfect yet. And we probably never will be. So, there will always be anecdotes. I think what’s – as a friend of mine puts it – the plural of anecdotes is not data. When I say, “Well, chemoimmunotherapy works.” It’s not because I have anecdotes of that, though anecdotes illustrate the magnitude of benefit.

I have data that shows that the chemoimmunotherapy regimen was compared to chemotherapy and was clearly and unequivocally superior. When I give a statistic that 60 percent of patients, 65 percent, can benefit from those types of regimens. That’s based upon prospective randomized control trials.

Patricia:

How about this one? Treatment is not effective in older patients.

Dr. Edelman:

Treatment is highly effective in older patients. It’s interesting. So, we had long arguments about, when I started in this field, whether treatment ever worked, and there were a number of studies that showed that chemotherapy – that one platinum was better – what’s called a platinum-based agent – was better than no therapy.

And then that two drugs were better than one drug. And people would say, “Oh, well, that doesn’t work in the elderly. And they should only get one drug.” And that’s because, I guess, their burning bush on the lawn told them this. And the fact is is that then got evaluated in a controlled trial, a very nicely done study by my European colleagues. But what was crucial was that they used somewhat lower doses of chemotherapy, a little bit different schedule of chemotherapy, and it was clearly superior to a single agent. And those were even days before immunotherapeutics and these targeted agents. So, many patients will benefit. You just have to be aware of certain basic principles in geriatric medicine as well as basic principles of lung cancer care.

So, first off, if the patient is elderly but their tumor is characterized by a driver mutation, they get one of the so-called targeted agents. And these are these days very non-toxic, easy to take, and highly effective.

Patients – many are going to be eligible for immunotherapy either as a single agent or combined with chemotherapy. Chemotherapy drugs could certainly be cut in their doses and still preserve much activity and be done safely.

I had a woman with small cell lung cancer. This is now about a year and a half ago or so. And she’s in her 80s. And she came to me because she was told – oh, just sorta get your affairs in order. And her disease was what we term an extensive small cell. The staging system’s a little bit different, but she didn’t have a really vast bulk of disease. And we treated her with standard chemotherapy drugs but at somewhat lower doses and some careful TLC and some other supportive things like growth factors.

She got all of her treatment on an outpatient basis, had an excellent response. We used radiation later to consolidate her treatment, and I see her back every couple of months. I wouldn’t say that she’s necessarily cured of her disease, but she does yoga every day. She lives a full life. She sees her grandchildren. And she’s, I think – I wanna say 83-84 years old. I think she’s quite grateful for that. It’s not the numerical age.

The flipside is if somebody’s 50 years old and they’re extremely ill when they come in, then one has to be very cautious about what one does. We used to say that those patients who come in who are severely impaired should simply get supportive care and hospice services.

And actually, how would I put it? Our lives have gotten a little bit more difficult lately because as things have gotten better for patients – because I can’t necessarily say that as much because some patients may be very susceptible to the effects of – their disease may be very susceptible to the effects of immunotherapy. I had one patient who was a younger gentleman who was on a gurney. He was in his 50s, lost an enormous amount of weight , he was on oxygen. We immediately gave him fluids. My fellow – I had an excellent fellow at the time – came to me and said, “Should we admit him and send him to hospice? Or just send him to hospice?” And I looked, and he had a biomarker that indicated that he might have an excellent response to immunotherapy, so we gave him solely immunotherapy and saw him back a few days later. He was still pretty touch and go. We gave him some fluids. A week after that – still, we were kinda touch and go, but he was still with us.

And then a week after that my medical assistant, comes in, and she says, “You know, he looks a little bit better today.” And he was in a wheelchair that day. And then a few weeks after that, he had a walker, and a few weeks after that a cane and about a year after that was asking me about whether or not he could go on a cruise. Again, I still see this gentleman – a couple weeks ago. It’s now almost two years later. And the question now that we have is – should we stop his treatment? And he is restored to complete full health, has had almost no side effects of treatment.

So again, this is not every patient. Some people will be treated and get every side effect and no benefit, but I think I’ve become a lot more reluctant to say that any patient should not at least be offered the opportunity for treatment knowing what the potential side effects are. And there still are considerable and sometimes severe side effects from therapy.

Patricia:

Sure. Here’s one I hadn’t heard until just now. Surgery causes lung cancer to spread.

Dr. Edelman:

Yeah, that’s common in certain states. When I was in Maryland that was a biggie.

So, there’s a myth that the air gets to the tumor, and then it spreads. But that’s certainly not true. It certainly is possible that in a bad surgical procedure that disease can be spread, but I think historically what that was was in the days before we had as accurate of radiographic studies. So, it’s kinda interesting. I always say, “I’m not that old, and I began medical school before there were CT scans.” So, the way you would diagnose something was with a chest x-ray. That was your best chest imaging. And the brain you’d image with something called a pneumoencephalogram, which is – you don’t know what that is. Most people don’t, and they should be thankful for that. But we had no real way of knowing these things. So, what would happen is there would be a surgical exploration. They would say, “Well, it looks very localized.” But then you’d go in, and there was lots of disease all over the place.

And for the most part, that doesn’t happen anymore. Now we have CT/PET scans. We have MRIs. Patients before they go to surgery usually have had – our pulmonary physicians will usually have sampled the nodes in the middle of the chest, the mediastinum. So, it isn’t that there aren’t surprises, but there are far fewer. And certainly, a properly done operation should not spread lung cancer. I would emphasize the properly done operation. It is my strong belief that nobody should have surgery for lung cancer from other than a board certified thoracic surgeon who spends their time thinking about lung cancer, preferably in an institution with a fair volume of this.

We know – it should be no surprise to people, practice makes perfect. People who really focus in an area – people at the NCI-Designated Cancer Centers, comprehensive cancer centers – who do a lot of this have greater expertise.

Transcript:

Patricia:

How are you approaching treatment decisions with your patients?

Dr. Edelman:

Well, the treatment decisions that we make – that I make are those that are in ways similar to other medical oncologists. It really depends because some of the patients may first go to a surgeon or whatever. However they come into the system, there are a few key factors in this. First is – make your decision based upon, Number 1, which kind of lung cancer. So, there are two major varieties. You have small cell and non-small cell, and they are treated – they are biologically distinct, and they are treated in distinct ways.

And then the next major consideration is the stage of the tumor, which is our way of expressing how advanced that is and deciding on both the therapy as well as conveying a prognosis and evaluating a patient for a clinical trial. And that’s based upon the size and location of the tumor; presence, absence, and location of lymph nodes; and the presence or absence and, these days, the number of metastatic areas of disease.

And then, lastly, and again depending a little bit upon the stage and interacting with all the others is what condition is the patient in? Anybody can get lung cancer, but still the median is in older individuals.

Many of these patients have compromised cardiac and pulmonary status as well as other diseases of aging, hypertension, cardiac disease, etcetera. Those people – one obviously has to tailor one’s treatments to fit those comorbidities. So, that’s sort of how the basic assessment – obviously, some patients show up with metastatic disease. We know that, but we go through a whole process for this.

The staging system that we use is complicated, and it keeps changing. We’re, gosh, up to version eight of this? I started with version three. I’m not quite sure I’ve fully mastered the current one, and the ninth edition is coming soon. And why does it keep changing? Because our knowledge of the disease keeps changing. The database keeps expanding.

We’re able to be more refined. Molecular variables have not yet fully entered into our considerations. Unquestionably, they will. But basically, one could consider lung cancer – despite the four major stages and multiple substages – that you really have three buckets that people will fit into. They have localized disease, which we will predominantly address with a localized therapy – surgery, radiation. And many of those patients, however, particularly those who might have a lymph node that’s positive, will benefit from chemotherapy to prevent recurrence.

We have patients with locally advanced disease. Primarily, those are patients who have lymph nodes located in the middle of the chest as opposed to more localized disease where if there’s a lymph node present it’s more in the lobe of the lung. Those patients with lymph nodes in the middle of the chest or larger tumors are approached with frequently a combination of chemotherapy, radiation, sometimes surgery.

And then we have patients with advanced disease who will be predominantly treated with drug therapies, which nowadays, depending upon the molecular background of the tumor, could be a targeted treatment if they have a specific mutation.

Something we see most frequently, though certainly not exclusively, in patients with scant or no smoking history, they may be approached with immunotherapy or chemotherapy combined with immunotherapy.

And there are many considerations that go into those decisions. And even in advanced stage, there are certainly roles for surgery and radiation depending upon whether there are structural abnormalities, occasionally whether there are relatively few areas or several areas of metastatic disease. And in the localized and locally advanced disease, our goal is cure in those, though we certainly are not there for every patient yet.

And in advanced disease, it’s extension of life, which is now quite considerable compared to untreated disease. And I think in certain situations, particularly those who only have a single area of metastatic disease, curative treatment is a realistic possibility. And even those with more disseminated disease, we’re now beginning to see a substantial fraction of patients who are still alive at five years or more. So, we’re beginning very cautiously to think that perhaps some of those patients may even be cured of their disease, though I’m not quite ready to say that.

Patricia:

How is genetic testing changing the landscape?

Dr. Edelman:

So, genetic testing – and in this case the testing of the tumor, not the germline, not the individual – has been very, very crucial. If you go back about 20 years ago, there was a family of drugs called epidermal growth factor receptor inhibitors or EGFR inhibitors.

And the basic science at the time made it look like these would be best combined with chemotherapy in squamous cell carcinoma. And as it turned out, combined with chemotherapy they weren’t very useful. But as single agents, there were these occasional very dramatic results.

So, that came at a time when we were able to evaluate tumor DNA, sequence it with some degree of ease at a reasonable cost. So, there was a discovery of specific mutations, which were targeted by these drugs. So, it was sort of interesting in that it was the clinical observation that led to the discoveries in biology, not really the other way around.

But then that in turn resulted in looking for other mutations, which were found, and then the development of other drugs – in some cases, the repurposing of other drugs for those. And now we have about a half a dozen very validated targets, each one of which in a small slice of the population – between say 1 percent and 5 percent – 10 percent of the lung cancer population – but these – if the patient has within their cancer that particular mutation, these are drugs that are 80 percent-plus effective and frequently can be administered with relatively little toxicity.

And usually they’ll give them benefit for one-plus years or more. So, that’s been an example of progress there.
