What is CLL?
Understanding CLL in layman’s terms
We spoke with CLL specialist, Dr. Kerry Rogers, about chronic lymphocytic leukemia, and how patients and their families can understand the disease.
“When thinking about CLL, it’s also important to realize that this is the most prevalent adult leukemia, meaning more adults live with CLL than any other type of leukemia.
People with CLL can expect to live a very long time, including their natural lifespan, and not everyone needs treatment. Because of that, it’s imperative to think about how well people are going to live with their CLL.
One thing that really helps people that’s not necessarily fancy is knowing how to look at your own blood counts.
People get these complete blood counts all the time, and you’ll see your white blood cell (WBC) count, hemoglobin, platelets, and then below that, you’ll see a differential that tells you what type of white blood cells those are.
You always want to look at the lymphocyte count, because the CLL cells are counted under lymphocytes. The other testing is something you do just on the leukemia cells.
It’s always very important to ask if this testing is done and what the results are so that you can know more about your CLL.
It helps you predict how much trouble you might have from the CLL in the future, the time before needing treatment, help in selecting a better course of treatment, how many treatments you might need in your lifespan, or if, at some point, a clinical trial might be appropriate for you.
The major ones are the IgHV and CLL FISH panel, which stands for fluorescence in situ hybridization. It is a chromosome analysis where they look at all the chromosomes because people with three or more changes in their chromosomes actually predict a higher risk of CLL.
They can expect to have more treatment and more difficulty with it in their lifetime. People with normal karyotype, like normal chromosomes, actually expect to have less difficulty.”
Is CLL leukemia or lymphoma?
Another CLL specialist, Dr. Jacqueline Barrientos, says there are two components of CLL:
- Blood cancer: it’s a disease of the blood. That’s the leukemia.
- Enlarged lymph nodes: the way that these cancer cells live and proliferate is by going to the lymph nodes. Once they grow in the lymph nodes, then they go back out into the blood.
Some patients present with only the enlarged lymph nodes and no evidence of leukemia in their blood. Those people are called SLL patients, which is like a sub-sub-type. They present a little differently, but it’s the same disease.
Categories and Stages of CLL
Dr. Rogers explains that the way to categorize and stage CLL is very different from solid tumors like breast cancer or lung cancer, where staging is determined by how much the cancer has spread in the body. For those solid tumor diseases, if the cancer has left the origin site, it complicates the prognosis and treatment options.
For blood cancers like CLL, the cancer goes where the blood goes, which is everywhere, so medical professionals cannot use the same basis.
The most common staging for CLL is called Rai Staging, developed by Dr. Kanti Rai.
- Stage 0: CLL cells are in the blood
- Stage 1: CLL cells are in large lymph nodes
- Stage 2: An enlarged liver or spleen from CLL
- Stages3 & 4: CLL cells are on the bone marrow that has caused people to have low hemoglobin, be anemic, or have a low platelet count from the CLL
How is CLL staged?
According to CLL experts we spoke with, patients go through physical exams and blood counts to get staged. Many people do not require a bone marrow biopsy, though some patients may undergo one to understand why their blood counts are low.
Dr. Rogers says the other focus here is on the main forms of CLL and if there’s a slow-growing or a fast-growing type.
Everybody’s a little bit different. You’ll see some people diagnosed with CLL, and they’ve had it longer than I’ve been a doctor, and they’re doing fine with it. Their white count is the same as it has been for the last couple of decades.
But there are people whose CLL isn’t moving very fast at all. Then, some were diagnosed 18 months ago, and their white count has gone from 15 to 200 over that time.”
Tests for CLL
There are multiple tests to determine whether someone has CLL, including some that help figure out whether the cancer is the slower or faster growing type. Here’s how Dr. Rogers described a couple tests:
IgHV mutational status
“One of those tests is called IgHV mutational status, or immunoglobulin heavy chain gene mutational status, where unmutated usually means a faster-growing, higher risk CLL.
I’d like to think of mutated as a special, low-risk slow-growing CLL, and that’s mutating your immunoglobulin as a normal process in B cells. This just says whether or not the CLL cells did that before they turned into leukemia cells.
FISH test for CLL
Some other tests that can help include FISH panel testing, which is just a fancy way to look at chromosomes in the CLL cells, not like the ones you pass onto your kid.
Things like deletion of the short arm of chromosome 17 or deletion of 17p can mean that we’d expect the CLL to be faster-growing, and deletion of 13q, which is part of the 13th chromosome, predicts slow-growing.
We can use a combination of these factors to guess how someone’s CLL will do.
Of course, sometimes we’re surprised. Sometimes, it looks like it will be slow-growing and it’s not, or people with some high-risk features really have an extended course but their CLL isn’t causing them any issues.”
When does a CLL patient need to start treatment?
This depends on a variety of factors, but a big one is focused on whether blood counts are abnormal, and if so, how much. According to Dr. Barrientos, “The majority of patients present with abnormal blood counts. The normal maximum number for white blood cell counts is 10,000.
Many patients present with 20 or 30. Over time this number can increase to even 40, 60, or 100. There is no magic number at which we decide to start therapy
We monitor and when patients show symptoms like anemia, low platelets or painful enlarged lymph nodes, then we’ll start therapy.Dr. Barrientos
There has been a significant amount of research dedicated to finding new treatments and therapies to help CLL patients of all ages.
But understanding what’s out there can feel so overwhelming. This page will feature all the programs and experts who highlight different treatment options and areas, taking out as much medical jargon as they can to help us patients and caregivers better understand what’s on the table.
Chronic Lymphocytic Leukemia (CLL) Patient Stories
From feeling their first symptoms, getting diagnosed, to managing through treatments like chemotherapy, stem cell transplants, and targeted therapy, explore the stories of chronic lymphocytic leukemia patients below.
Tony D., Chronic Lymphocytic Leukemia (CLL)
Cancer details: ~25% of new cases of leukemia, also classified as non-Hodgkin lymphoma (slow-growing)
1st Symptoms: Lump in back of neck that got bigger in a couple weeks
Treatment: Chemo pill (Imbruvica), takes 3 pills a night
Dr. Rogers, an associate professor and hematologist/oncologist at Ohio State University’s The James Cancer Center, shares in-depth insights into her work on CLL treatments, as well as a study on the much rarer hairy cell leukemia.
Many people diagnosed have no symptoms whatsoever and are sometimes somewhat confused about going to the cancer hospital to meet with me.
Dr. Barrientos, an associate professor of hematology/oncology and oncology research at Northwell Health, talks through what CLL is, treatment options, and the trend of drug research.
Many times, people don’t really want to know about it and just want to listen to their doctors. The field is changing so quickly that I think the most important thing you can do is to be an advocate for yourself.
Dr. Tim Fenske, an associate professor and hematologist/oncologist at the Froedtert Hospital Cancer Center, discusses what determines whether someone needs treatment, and the focus of newer CLL drug research.
Really, in the last year based on some recent studies, most experts in the field agree that there’s very little if any role for conventional chemotherapy in the frontline for CLL.
Navigating Life with Cancer
A cancer diagnosis leads to many more questions than ones about medical treatment. How do I break thew news to friends and family? Will I lose my hair? Do I need to advocate for myself right now?
