Fact or Fiction? CLL Causes and Symptoms


Transcript:

Dr. Brian Hill:

So, chronic lymphocytic leukemia is a term that refers to a cancerous condition in which the abnormal or cancerous white blood cells are a type of B-cells with certain characteristics that are present above a certain threshold in the blood. Those same cancer cells can also grow and divide and set up shop in other organs besides the blood and bone marrow.

And that can be a lymph node, spleen and sometimes we find the exact same type of cell in a lymph node or other parts of the body. And we don’t find it in large quantities enough in the blood. And when that happens, we call it small lymphocytic lymphoma or SLL. So, people get very confused by the terminology, “Do I have leukemia, or do I have lymphoma.” And so, a lot of times there’s a reference to a condition called CLL-SLL. CLL-SLL really is one disease.

And the term leukemia or lymphoma really just refers to where is the predominant location for the abnormal cancer B-cells. Are they in the blood or are they in the tissue?

If it’s in the blood, mostly above 5,000 cells per microliter, that’s the cut off. If it’s in the blood predominantly, it’s CLL. But if those same cells are in the lymph nodes or the spleen but not above that threshold of 5,000 in the blood, then the term is small lymphocytic lymphoma. And often times that diagnosis made from a tissue biopsy or a lymph node biopsy rather through a blood test or a bone marrow biopsy. Really, these are the same disease. And even physicians who don’t practice in this area get confused about it.

And it’s important to know that they can be treated exactly the same and are interchangeable. Rarely I’ve seen a mistake be made that someone who has a diagnosis of SLL or small lymphocytic lymphoma is treated with the types of chemotherapy drugs that we would typically use for indolent forms of lymphoma.

And some of those therapies overlap. So, there are biologic similarities and clinical similarities between B-cell lymphomas and CLL-SLL for sure. But there is a lot of nuance in B-cell lymphomas, and not every single treatment that works really well for B-cell lymphoma should be used in CLL or SLL.

Not to Worry! Your Guide to Watch and Wait

Not to Worry! Your Guide to Watch and Wait from Patient Empowerment Network on Vimeo.

 Watch and wait, or active surveillance, often feels like watch and worry to CLL patients. Dr. Brian Hill provides a comprehensive guide to the period of time before CLL treatment begins and shares approaches for managing anxiety.

Essential Lab Tests for CLL Patients

Dr. Brian Hill:

So, watch and wait is the term that’s referred to for not actively treating a patient with CLL after the diagnosis. As many people probably out there watching know, the diagnosis of CLL is often made incidentally or accidentally through routine laboratory tests that are done for some other reason.

Maybe they are going to have surgery. Or maybe they are going to have just a primary care checkup. And blood count shows too many white blood cells. And everything else is fine. The patient feels normal. There’s no symptom. But it leads to a referral usually to a hematologist who then does more testing and makes a diagnosis of chronic lymphocytic leukemia. The word leukemia is very scary because it often conjures up images of acute leukemia which is a disease that can make people very sick very quickly.

We’re taught in much of medicine and in much of cancer that early diagnosis and early treatment is very important. And it is very important for many conditions – breast cancer or we’re taught let’s get our mammograms.

And have an early detection and immediate treatment to cure the breast cancer. Similarly, colon cancer – get your colonoscopy, get your diagnosis sooner rather than later. And have surgery so you can have a higher likelihood of a cure. In the case of chronic lymphocytic leukemia, it’s never been shown despite multiple attempts over many decades, that treating someone with CLL is – earlier, is going to impact the outcomes and the big picture. But we do know that treating CLL earlier can lead to more side effects earlier.

So, in other words, if you feel fine and your blood counts are just a little abnormal, and there’s not compelling indication to treat, we can safely observe patients until an indication for treatment exists. And what I tell patients is that if we treat today, the treatment will work.

If we treat tomorrow, the treatment will work. And if we treat in five years, the treatment will work. So, there’s – we have very good evidence that delaying treatment until you need it does not compromise the likelihood of the treatment working. So, it’s a little bit of a different mindset from other types of cancer where we are taught to treat early and immediately. So, a lot of times people will call it watch and worry instead of watch and wait, and there’s a lot of anxiety about that.

Again, their diagnosis has the word leukemia in it. It can be a very scary time. And it takes a little bit of trust to be convinced that you don’t need to be treated just because you have it. And that’s often times when we do get second opinions if the first hematologist/oncologist says it’s okay to watch it and wait. We don’t need to treat. A lot of the time people then seek another opinion to confirm that’s accurate. And in most cases – I would say 90% of the time when I’ve had a second opinion for a patient who’s been recommended to watch and wait, I typically concur with that recommendation.

So, during watchful waiting or – I like to call it active surveillance because it’s not that we aren’t doing anything, we are surveilling or monitoring. And the two things that we monitor are symptoms and blood counts. So, it sort of begs the question that many people ask which is, “If you are not going to treat me now, when will you treat me? When will I need to be treated?” And the first indication – the first thing we look at is symptoms. So, if you have symptoms of significant fatigue to the point where you are really having a difficult time functioning.

Or if you have drenching night sweats that wake you up from night and make you change your nightclothes. Those type of symptoms would push us to treat. So, those are the things that are being asked of patients at their regular follow up which is usually every two or three months initially.

And sometimes can be spaced out to every four to six months if things are stable. But usually during the first year you want to be checking on folks every two to three months. Weight loss would be another symptom to look out for – sort of unintentional weight loss. The other thing we monitor is the blood counts. So, with a simple CBC or complete blood count, we can see what is happening with the white blood cell count which may and often goes up.

And a lot of folks focus on the white blood cell count and its trajectory and how that is rising. Some people’s white blood cell count can fluctuate. Others can stay relatively flat. And some people do have a continued rise on the white blood cell count. The white blood cell count in and of itself is not the final reason to recommend treatment.

But with time, as the white blood cell count goes up, we sometimes see the other numbers going down. And actually, the other numbers going down are the ones that are more important. Those numbers are – the red blood cell count measurement which is usually measured by hemoglobin concentration or hematocrit. And then the other is the platelet number. So, if either the hemoglobin or the platelet number gets below threshold, those are typically indications for treatment.

So, during this period of observation or active surveillance – watchful waiting, whatever term you choose. This can go on for years.

And it can be associated with anxiety. So, trying to do things to cope with managing anxiety is important. Other things that many people are interested in are – is diet. So, do we know of a particular food or food group that we should focus on? Or is there something we should avoid? And the short answer to that is that many – it’s a difficult topic to study. As you might imagine, diet can be so varied around people. And in a typical week the average person eats so many different types of foods that it’s difficult to focus in on one particular thing.

What we can say is that in general for health, clearly fresh fruits and vegetables are the best source of nutrition. And also, are best for your health.

Avoiding processed foods and processed meats and other foods that are high in saturated fats is probably important in general for your health. Although we can’t say specifically that it’s definitely going to make an impact in the white blood cell count or the trajectory of the CLL. In terms of supplements and natural products, many people are interested in this topic. And again, it is a difficult one to study. Some of the natural products out there are purified forms of things from plants and other ingestible herbs and so forth.

But the problem is, is that if you take any component – even if it’s natural occurring, take it in large quantities it can lead to other problems. There was a well-known study from – that studied the impact of green tea extract on the white blood cell count.

And if you took large quantities of green tea extract, it seemed as if it did sort of lower the white blood cell count a little bit. But some people also had abnormalities of their liver function as a result. So, I don’t recommend green tea extract. And I instead say, “If you like tea and you want to drink green tea, I think that’s probably fine.” But I wouldn’t do it in excess. And just maybe try to incorporate it into a balance diet otherwise.

Dr. Brander:

There are several factors to take in consideration when discussing individualized treatment approaches or options for patients.

Broadly, this can be divided into patient-specific factors, and then CLL-specific factors. And what I mean by that is patient’s age, even for patients very fit, we know from clinical trials that there’s a different processing, tolerability, and benefit of certain chemotherapies and a higher risk of certain side effects, even with the novel therapies as patients advance in age.

There are other patient-specific factors such as there are other medical problems. We often call these comorbidities. These are things like cardiovascular or a heart problem history, diabetes, kidney function differences. A lot of those factors play into individualizing when you know different treatment side effects what might be the best option for patients.

In the CLL-specific factors, these are some of the markers and characteristics that we have talked about in terms of FISH testing, TP53 mutation status, and IGHV mutation status. Based on recent clinical trials for patients receiving first treatment, if there are any changes, which historically chemotherapy didn’t treat the CLL for as long as we would have liked, we tend to err towards the novel agents for sure. And even across all markers, there can be a benefit of the newer drugs such as ibrutinib or venetoclax, or many of the other next-generation inhibitors that are in development. But for sure, patients with deletion 17p or TP53 mutation should never receive chemoimmunotherapy.

There’s a lot of research going into understanding what other CLL-specific markers may benefit for one treatment type versus the next. And we hope that all patients could potentially benefit from clinical trials both in the options that are offered as well as some of this other testing, which is how do you determine which markers are important for patients in the era of the drugs that we have today.
