Dr. Nicole Rochester: 

We know that no two lung cancers are the same. Can you explain to the audience how biomarkers help with lung cancer treatment and they can be so important? 

Dr. Christian Rolfo: 

Yeah, we have different…as I say, we are looking at specific characteristics from the tumor when I’m referring to genomic alterations that I’m not referring to something that you can get from your family and bring to your descendants. So I’m talking about mutations that are occurring inside the tumors and only for the tumor, and so affecting only the subject that has this patient that has this alteration. So these biomarkers are an important way to identify populations that we can treat specifically, and I would like to be a little bit more specific on that. We have some of the alterations, for example, one of the mutations that we call EGFR or epidermal growth factor receptor mutation that is supported in different populations in different frequencies. For example, if we have patients that are with an Asiatic origin, we have there the possibility to have a…and I’m referring, for example, Chinese, Japanese, this area of the East Asia, we have a hyper-prevalence of these mutations in around 50 percent of the patients with lung cancer, non-squamous we’d say this is another characteristic of the tumor can have this specific alteration. If we are moving, for example to Latinos, the pains of the areas of Latinos they are coming from, if you have Mexican or, for example, Peruvian, they have also due to their ancestry, they are similar to the Asiatic population, 40 percent we’re going to white populations and Anglo-Saxons or Europeans, they have around 7 to 15 percent  according to the different regions. 

African Americans within 15 to 20 percent. So these kinds of alterations are giving us the opportunity to treat and we have nowadays inhibitors and that’s drugs that are from first, second and third generation, so we were evolving in January, this pharmaceutical in January to develop all drugs that are able to penetrate in the brain and acting not only in the tumor, but also in brain metastases. And patients who have this mutation, for example, are treated in first line, in front line, or the first treatment that they receive are pills, no chemotherapy. So for this reason, and that is something that is important because when we know that patients, when they start this journey of lung cancer diagnosis before they see an oncologist, they were struggling to get the diagnosis and then we’re passing through several doctors from the general practitioner or to the emergency room, going to CT scan and then a biopsy then a pulmonologist until they get the diagnosis, it’s a big period of time sometimes that we are very nervous because we want to each patient to have a treatment as soon as possible, and sometimes when they arrive to us, we say they need to wait until we have the results of these biomarkers. 

So it’s difficult to understand, I put in the place of the patients and the families are really difficult to understand that I was passing a lot, I went here, I came here and I want your treatment right away, but this period that we are asking to wait is really important, because we will have information that can change radically the treatment and the history of these patients. So one of the problems that we have in America is the lack of testing, so we have all the tools to test the patients, but if we are looking at some of the statistics, 50 percent of the patients have been tested. 39 percent if we are moving to groups, for example, of AfricanAmericans, so we need to be very careful that don’t push to get the treatment very quickly without having all the elements to this thing, which kind of treatment is the most adequate for the patient. 

Dr. Nicole Rochester:

That is such important information, and I really appreciate that, I appreciate it. That you put it in the perspective of the patients and family members. And that grueling, long wait, long time to diagnose this, and finally you’re in front of a specialist and the perception is that, Okay, now I’m going to get this treatment that I need, and then like you said to hear, now you have to wait a little bit longer, but also to understand that that wait is important to make sure that you get the treatment that is meant for your specific type of cancer, I think that is so incredibly important.

Dr. Christian Rolfo:

And believe me, we are trying to push as well from the that there are, unfortunately, technical times that we cannot overcome that are for testing and for having these results, and we can do that by like I said liquid biopsy, but also tissue biopsy, so we are sending the tissue that the patients gave for a biopsy in a biopsy or in a resection when they have surgery. We take these small biopsies and we send them for analysis and take longer sometimes, so it’s a pity and we know, but it’s the only way to go for the right treatment.

Hi, I’m Kendra. I’m a nurse practitioner and I specialize in lung cancer.

When diagnosed with lung cancer, it’s important to take steps to get a deeper understanding of your disease, and the available treatment options, so that you can feel confident in your care decisions.

Before we walk through the actions that can help you decide on a treatment path, I want to remind you that this video is intended to help educate lung cancer patients and their loved ones and shouldn’t be a replacement for advice from your doctor.

OK, let’s get started.

The first step is to understand your diagnosis—including the type of lung cancer and stage of disease—so that you can find out what treatments are available to you. Your physician will use tests, including biopsies and imaging, such as X-rays and CT scans, to ensure you have an accurate diagnosis.

The next step is to understand the approaches available for YOUR individual disease.
Depending on your stage and type of lung cancer, treatments can include:

  • Surgery
  • Radiation therapy
  • Chemotherapy
  • Targeted therapy or
  • Immunotherapy

Or, you may receive a combination of one or more of these treatments.

Other testing that can impact your treatment options is molecular testing, which is used to identify specific mutations that are unique to your lung cancer. This may help in deciding if targeted therapies are an appropriate option for you.

Before you start any treatment, it’s essential to ask your doctor if you have had relevant molecular testing.

Another option that your physician may discuss with you is clinical trials, which may provide access to treatments that are not yet approved. At different points on your path with lung cancer, it’s important to talk with your doctor about whether there is a clinical trial that could be right for you.

Once you understand the treatments that are available to you, it’s time to talk to your doctor about the risks and benefits of each option and walk through the goals of your treatment.

One of the most important factors that your healthcare team will consider is YOUR treatment goals. Remember, you are a partner in your care and have an active voice in finding the best treatment for you. Physicians also typically consider a patient’s age, overall health, and existing conditions before they suggest a course.

So, what questions should you address when you are discussing your treatment goals with your doctor? Consider asking:

  • Is the goal of the treatment to cure your disease or to obtain long-term control your disease?
  • How effective will the treatment be and how will it impact your quality of life and lifestyle?
  • What are the treatment side effects–both the short-term effects as well as long-term effects that may occur after you have completed treatment?
  • Is there a member of the team, such as a social worker, that can help you understand the potential treatment costs? And is there access to financial resources that can help you if needed?
  • Are there supportive care options that can help with symptoms and pain management at any stage of your cancer?

It also may be a good idea to consider a second, or even third opinion consultation with a specialist. And, if you don’t feel supported or you don’t feel heard by your healthcare team, then it is always best to get another opinion.

Finally, once you have gathered all the information, it may be helpful to talk it out with people you trust, such as a partner, friend or family member, to help you make a decision that you feel confident about.

Now, how can you put this information to work for you?

  • Make sure you understand your type and stage of your lung cancer and the goals of your treatment options.
  • Talk to your physician about what you’ve learned.
  • Consider a consultation with a lung cancer specialist.
  • Ask about molecular testing and what testing results mean for you.
  • Discuss whether clinical trials are an option for your cancer.
  • Visit credible online resources to stay up to date on lung cancer information.

Dr. Erin Schenk:

As a medical oncologist who takes care of lung cancer patients, I would recommend that if you or a loved one are diagnosed with lung cancer, going to your meeting with the cancer doctor report the surgeon or the radiation doctor with a couple of main questions to ask in order to better understand your diagnosis and the treatment options.

So, the first one is what stage and stage is a descriptor that we use that talks about how far the lung cancer has spread if it’s spread at all. And sometimes, this involves additional testing to give you the best, most accurate answer. Oftentimes, patients are diagnosed with scans, but what’s also – excuse me, scans of the chest, but what’s also really important is better understanding whether or not lymph nodes in the middle of the chest are also involved.

This can require either a PET scan or occasionally procedures where tissue, the lymph nodes biopsied, and tissue samples are taken to see if the lung cancer has spread to those lymph nodes. PET scans are also able to better tell us whether or not lung cancer has spread outside of the lungs. And additionally, and MRI of the head can often be a really critical piece of information to better understand whether or not the lung cancer has spread to the brain. Unfortunately, lung cancer is one of those cancers that can spread to the brain tissue.

So, the first piece of information and more tests might be needed, is stage.

The second piece of information that’s very important is what type of lung cancer, and sometimes, this occurs hand-in-hand with better understanding stage. Usually, this involves a biopsy, so a sample of the tissue needs to be taken and then looked at underneath a microscope by a pathologist who are doctors who help us identify which type of lung cancer it is that a patient has. And then the final thing to ask your care team or your doctor is do I need additional molecular testing?

Molecular testing is a critical piece of information in order for doctors like me to help take care of lung cancer patients. Molecular testing lets us know what role immunotherapy might play in your diagnosis. It also lets us know whether or not targeted therapy which are oral pills we sometimes call TKIs are appropriate for your disease and your stage. These pieces of information, so stage, what type of lung cancer, and if molecular testing is necessary, these are, I think, the three critical pieces that you need going forward to help your cancer doctor and team better formulate a plan that is right for you.

Finally, I’d like to add in that if you are in a situation where you would like a second opinion, or you would like to get more thorough answers, I would encourage you to look for an academic center or a large medical center that has specialists who focus in on lung cancer. We are often very happy to see patients and talk with them about their treatment plan if any other tests or evaluations are needed to help you feel confident in the plan that your doctors closer to home have put together. That’s it.

Dr. Erin Schenk:

We have a very active clinical trial practice in the lung cancer world for one reason alone, and that’s that while our current therapies are good, we can still do better. Lung cancer accounts for significant cancer-related deaths in the United States and the world. And we wanna work to try and improve how well patients do and also improve how many patients we are able to cure. Clinical trials can be at any step of your workup or treatment.

So, even patients with earlier-stage disease meaning lung cancer where we can resect it with surgery, there are a number of clinical trials going on right now to try to better improve the outcomes we see with our normal standards of care. So, whether you are having a lung cancer removed by surgery whether you’re receiving chemotherapy and radiation and immunotherapy whether your lung cancer has happened to spread outside of the lungs, there are clinical trials available at every step in the game.

And I would really encourage you to ask your cancer care team or your doctor about whether or not clinical trials might be available in your area. Because often, they can help identify new targets or other ways of trying to attack the vulnerabilities of your lung cancer.

If you are considering a clinical trial, there are a number of important questions to find out from the clinical trial team as well as your cancer care team. Some of the things are really practical, logistical questions and one of those is, “How often do I need to come to clinic? How many more schedule visits do I need?”

Usually, with clinical trials, upfront so before you get on the clinical trial or once you start receiving the clinical trial medicine or therapy, often there are more frequent visits in that initial time period. But after things are – after you’ve had several treatments with the trial medicine, often it becomes more standard of care meaning visiting once every three weeks for blood work and a visit with your team and then infusion.

So, it’s often a little more work up front, and then it gets back to the usual expectations of how often you have to be in our offices. So, I think those logistical concerns are very real because especially for larger institutions, sometimes, coming to our campuses can be a bit of a challenge. So, that would be one. I would recommend discussing logistics. Discussing with your team as to why they think this would be a trial for you is important.

Occasionally, we are able to screen for certain markers or certain things that are expressed on the cancer cells and then match you with clinical trials that try to target those specific molecules or proteins or flags that are on the surface of the cancer cell. So, oftentimes, we try to match patients up to a specific clinical trial, so better understanding why that one was recommended. And then I would ask your team to also discuss what are the side effects that have been noticed.

Often with these clinical trial medicines, we don’t have a lot of experience with how well patients do on these therapies. But sometimes, we can give you an idea in terms of what we expect and what we will watch closely for. So, I think logistics are important, why your doctor or your cancer team thinks this is a good trial for you, and then finally, what sort of side effects have been noticed as best we can tell with this new trial medicine.

Dr. Erin Schenk:

Some interesting research that’s coming to the forefront in the lung cancer field are using new medicines called antibody-drug conjugates. And so, these medicines, I think of as another type of targeted therapy. So, what happens is that cancer cells express certain proteins or certain flags on their surface that aren’t often found on other normal cells.

And what these ADC drugs are able to do is that they’re able to seek the cells that express certain flags, and then deliver a chemotherapy payload directly to those cancer cells. One trial from the recent ASCO annual meeting from this year, 2020, was looking at an ADC that targeted HER2 which can sometimes be over-expressed by lung cancer cells.

And they had good initial reports in terms of patients being able to have disease control for some time and minimal side effects.

So, I think in general the idea of ADCs or looking for surface markers on the cancer cells to try to in a more targeted fashion deliver the chemotherapy payload, I think this is a really exciting area of investigation as well as a new potential therapy for our patients with lung cancer.
