Lisa:

Dr. Gong, how do you explain stomach cancer to your newly diagnosed patients and care partners? And really important too, how do you explain disease staging to them?

Dr. Jun Gong:

So the way I explain stomach cancer or gastric cancer, is another term for this disease, to my patients is that we all are familiar somewhat with our organ that is the stomach. This is the organ that helps digest and process our foods. And it’s the organ that connects to the esophagus and then to the small bowel. And unfortunately, cancers can arise from this organ. And this is where it’s a little bit unique in the sense that unlike other cancers, the stomach is almost like a tube. It’s a hollow structure.

Unlike breast cancer, for example, where you can have a discrete mass where you can actually draw on a caliper and say this is 2 centimeters or 3 centimeters in dimension, stomach cancer tends to grow along the walls of this tube infiltrating to the inside of the lumen. Or it can even spread to the outside of the stomach as well. 

And so this is how the staging is a little bit different for stomach or gastric cancer. And the way, instead of measuring by size, we measure how the depth of the infiltration of the tumor is along the thickness of the wall. And so the staging is similar to other cancer types where there’s a stage I, II, III, or IV connotation. And stage IV means that the cancer has spread outside the stomach and into distant sites such as the liver or lungs, while tumors of the stomach that are confined to the stomach and even to the lymph nodes around the stomach are still classified as I, II, or III. So this is a little bit about, a background, about how we explain what stomach cancer is and how the staging system works.

My activation tip for patients and care partners who are newly diagnosed with gastric or stomach cancers and are unsure about their stage is that it is always more than appropriate to ask the physician or care provider, “What is my stage of stomach or gastric cancer?” and we will do our best to explain the stage. And, of course, this is dependent oftentimes on the availability of information from a diagnostic workup. And how we stage the patient is usually dependent on imaging such as CT or MRIs or PET scans. And it’s often combined with ultrasound or endoscopic procedures such as an upper endoscopy or an endoscopic ultrasound, which is a specialized procedure that allows you to look within the thickness of the stomach to see how deep or how depth of the invasion of the stomach cancer is.

Katherine:

Yeah. Well, now that we understand a bit more about what it is, let’s walk through the process. When a patient goes through CAR T, what happens first? 

Dr. Richard:

So, the first step is being referred to a CAR T physician. Right now, CAR T therapies can only be done in certain tertiary care institutions, not even all tertiary care institutions.  

They have to have the ability to manage and process cellular therapies. So, that’s limited right there. So, patients have to be referred to centers, so actually do these CAR T kind of therapies. Once they meet with the myeloma physician who deals with CAR Ts as well, then the way it works in our institution is then we assess them for which is the best kind of CAR T product the patient may be eligible for. Are they eligible for clinical trials? Do they fit the profile for clinical trial? Are the patients willing for clinical trails? If not, are they candidates for one of the commercially approved products? As I said, there is specific criteria. Patients have to have had at least four lines of therapy to be able to receive a commercially approved CAR T product.  

If that is the case, and once the process has been explained to the patient, they have to go through all the financials, the insurance approval. These are very expensive propositions. So, the insurance goes through all of the criteria to make sure that they will approve the product. Once the insurance approves, they also going through the institutional approval process to make sure that these are again being done for the right patient, and that they go through the institutional approval.

There are several patient specific characteristics. For instance, we want a patient who has the support structure to be able to support a therapy like this. They have to have a good performance status. They have to be relatively able to be able to handle these kinds of therapies. I went through all of those side effects that are possible. We look at their cardiac status. We look at the neurological status.  

We look at the pace at which their disease is escalating because these are again advanced patients. So, if somebody is relapsing very quickly, they may not have the time to wait to get to a slot for the apheresis, and then to wait again for the manufacturing to happen. So, we look at all of that. We look at their kidney function. And then finally in terms of their psychosocial, do they have their caretakers, the support system? Where do they live? Are they able to access our center? Are they from out of state?

If so, how are we going to manage during those initial months until they’re able, stable enough to be discharged back to their referring physician? So, we look at several things, so we have multiple teams of people, social work, pharmacy who looks at all of these different – and explains the pharmaceutical aspects of all of this, our finance team, our coordinators who put all of this together.  For the apheresis, we are involved with an apheresis team.  

And then the cell therapy lab that processes the cells, the vascular team to put in the lines required for the apheresis. So, there are several, several groups. And then if we need to get a consultation from our expert cardiologist or neurooncologist, we need to have those teams involved as well.  

Katherine:

How long does it take to know whether the treatment has been successful? 

Dr. Richard:

So, we get a sense depending on what their blood markers look like, we can get a sense within the first month if the patient is actually responding to the treatment or not. I generally wait for the first three months to do a actual formal assessment with their bone marrow and their PET scans and everything else because right around then they’ve gone through the initial acute post CAR T period. And so, at the time of the bone marrow we assess what it looks like, we send for a test called MRD which is minimal residual disease to see where they’re at with that. 

And PET scans to look at any areas of skeletal lesions or even extramedullary disease that they may have. So, I would say within the first month we get a sense, but by three months we do that first formal assessment.

Transcript:

Katherine:

I’d like to talk about what goes into deciding on a treatment path. What testing is used to understand a patient’s individual disease?  

Dr. Gao:

There is a lot of testing that we do for – to try and characterize a patient’s individual disease and try to select an optimal management strategy for their specific cancer and their specific situation.  

We look at the biopsy, the pathology. The most common type of prostate cancer is called adenocarcinoma, but rarely we see certain other types under the microscope, things like neuroendocrine or small cell prostate cancers that tend to be treated in a different way. We look at things like the Gleason score.  

That tells us a bit more about sort of the aggressiveness of this cancer, as well as the PSA, you know, it’s a very good correlate for how the cancer is doing in general once somebody has been diagnosed with prostate cancer. For imaging tests, we commonly rely on imaging. We look at prostate MRIs to get an idea of the local extent of the prostate tumor. We get things like bone scans and CAT scans to look at the entire rest of the body to see if or where the cancer may have spread to.  

And there are newer imaging tests like the PSMA PET scan, which we commonly use now, which is a much more sensitive test for detecting prostate cancer in 2023 compared to traditional scans like CAT scans and bone scans. I also commonly make use of genetic testing and molecular information.  

So, for any patient with an advanced prostate cancer, I do recommend both what we call a germline test, which is testing for inherited cancer genes that a patient could have gotten from the parents and pass onto their kids, as well as somatic testing, which is testing the cancer itself to see what genetic mutations or alterations might’ve developed within their cancer. And that can actually factor into certain treatments that the patient may or may not be more likely to benefit from if they have these genetic mutations. 

Katherine:

Dr. Gao, a patient sent in this question prior to the program. What other genetic testing, beside BRCA markers, are important for deciding future targeted therapies and how are each of them used? 

Dr. Gao:

Yeah, that’s a great question. Targeted therapies have been used in a lot of different cancers and it’s only really within the past few years that we’re using them as a standard of care routinely in prostate cancers. So, BRCA2 and BRCA1 mutations are some of the more common mutations or genetic alterations that are targetable in prostate cancer. Recently, there have been multiple FDA approvals of different drugs that are called PARP inhibitor, which are able to target the cancer if they have BRCA1 or BRCA2 mutations.  

Beyond BRCA2 and BRCA1, there’s a panel of what’s called homologous recombination repair genes and that’s defined differently in varying extents, depending on the specific drug. That has been FDA approved, but in general, it’s about 12 to 14 genes total and they actually include the BRCA2 and BRCA1 genes.  

So, some of the ones that have been…it seems like the data shows maybe more activity or better efficacy with these PARP inhibitors include a gene called PALB2, P-A-L-B 2. It’s not a very common mutation that we see, but it is something that we should look for because even if it’s not common overall for the patient who has it, it could be a very helpful and useful gene to know that that they have and it certainly would warrant treatment with a PARP inhibitor. 

The other sort of dozen  or so…10-12 genes in this homologous recombination repair pathway, the data, I would say, is still early and it is still somewhat limited in terms of how much people with those gene mutations truly benefit from these PARP inhibitors, but I do think it’s important to look for them, to know that if they do have one of these genetic mutations that it does make a PARP inhibitor an option for them. And then, beyond these HRR genes, I always look for something called a microsatellite instability or mismatched repair deficiency. These are sort of genetic features or really a panel of about four genes involved in a cellular process called – a DNA repair process called mismatch repair.  

For those patients that have either mismatched repair deficiency or microsatellite instability high cancers, I do recommend that they consider an immunotherapy medication called pembrolizumab which is FDA-approved regardless of cancer type for any MSI high or mismatched repair cancer and they’ve shown pretty solid activity for those kinds of cancers. 

Becoming an Empowered and [ACT]IVATED DLBCL Patient

/in , , , , , , , , , /by

Patient Empowerment Network (PEN) is committed to helping educate and empower patients and care partners in the diffuse large B-cell cancer (DLBCL) community. DLBCL treatment options are ever-increasing with research advancements in treatments and testing, and it’s essential for patients and families to educate themselves with health literacy tools and resources on the latest information in DLBCL care. With this goal in mind, PEN kicked off the [ACT]IVATED Diffuse Large B-Cell Lymphoma (DLBCL) program, which aims to inform, empower, and engage patients to stay abreast of up-to-date information in DLBCL care.

The [ACT]IVATED DLBCL program is aimed at newly diagnosed DLBCL patients, yet it can help patients at any stage of disease. The initiative aids patients and care partners stay abreast of the latest options for their DLBCL, provides patient activation tools to help overcome barriers to accessing care, and powerful tips for self-advocacy, coping, and living well with cancer.

Diffuse Large B-Cell Lymphoma Disparities

Clinical trials are the primary way to forge DLBCL research and treatment advancements. Yet Black and Hispanic patients have been subject to clinical trial exclusion criteria at a higher rate than white patients. A recent DLBCL study showed that levels of lab test criteria of platelet count, hemoglobin, neutrophil count, bilirubin, and creatinine was responsible for the exclusion of 24 percent of patients who applied for clinical trial participation. And Hispanic and non-white DLBCL patients were more likely to be excluded from trials based on these lab test values – a clear disparity in DLBCL care.

Dr. Shah's [ACT]IVATION Tip

Access to specialized DLBCL care and clinical trials are important for all patients. Cancer patient Lisa Hatfield interviewed Dr. Nirav Shah, Associate Professor at the Medical College of Wisconsin. He explained about the barriers to care that some patients experience. “…I think that just simple geography is an issue that creates accessibility and impacts the type of care that a patient is able to get. I think beyond that, there are obviously economic factors that drive a patient’s ability to get specialized treatment. Do they have money to afford the gas to get to a larger center? Do they have the resources or the support system available to get a complex therapy where you would need those treatments, especially for relapsed disease? And then I think there are always going to be racial factors and accessibility issues that happen, where patients aren’t referred in time or patients aren’t getting necessarily the best care that they can.”

Solutions for Improved DLBCL Care 

Dr. Nirav Shah shared about the impact of clinical trial participation. “We wouldn’t have CAR T if hundreds of patients didn’t go on these clinical trials and be willing to be a subject and go through a treatment that was at the time undefined and without knowing how efficacious it was going to be.…clinical trials are important because without patients participating in clinical trials, how can we do better?”

In order to improve and refine DLBCL treatments, more research must be carried out. Dr. Nirav Shah shared where things stand with DLBCL types and how optimal treatments may be found in the future. “…there’s something called the germinal center phenotype. The other one is called the activated B-cell phenotype and prognostically, these sort of behave differently. Currently, we’re treating them the same, but we’re hoping that in the future, we’ll actually have algorithms that are more refined so that they are giving the best treatment for each subtype.” 

“So I know that in the world of diffuse large B-cell lymphoma, we have lots of great treatments, which is the exciting part for me. My biggest concern remains that not all of those treatments are accessible to all the patients that they need them, and I think we all need to do a better job of educating our community, of making people aware that these options are available, and then also facilitating patients who have less money, patients who have less resources to be able to provide them what they need to be able to get the treatments that are best for them.”

Healthcare providers are available to help DLBCL patients. Make sure to ask about a phone number for you or your loved one experiences concerning side effects. Dr. Nirav Shah explained the importance of staying in touch with the care team. “…call us. Let us know what’s going on. We can’t help you with your symptoms if we’re not aware, and we don’t mind those phone calls because we want to help patients through that journey.”

Dr. Shah also shared his perspective about DLBCL treatment advances and how hopeful he is about the future of DLBCL treatment. “…there have just been incredible advances, not just in chemotherapy, but immune therapy and targeted therapy, and so the goal is to keep getting better. I see a future where more and more patients with diffuse large B-cell lymphoma are cured in the front line, and more and more patients are cured in the second line.”

[ACT]IVATED DLBCL Program Resources

The [ACT]IVATED DLBCL program series takes a three-part approach to inform, empower, and engage both the overall DLBCL community and patient groups who experience health disparities. The series includes the following resources:

Though there are DLBCL disparities, patients and care partners can take action to educate themselves to help ensure optimal care. We hope you can take advantage of these valuable resources to assist in your DLBCL care for yourself or for your loved one.

Biomarker CA-125 and Renal Medullary Carcinoma: What Do We Know? from Patient Empowerment Network on Vimeo.

What is known about the renal medullary carcinoma (RMC) biomarker called CA-125? Expert Dr. Nizar Tannir explains how the CA-125 biomarker has been analyzed and further studies of the biomarker used along with other RMC testing.

[ACT]IVATION TIP

“…another valuable information to have, but it has to be interpreted in the context of other things in the context of how the patient is doing, whether they have symptoms that are improving or getting worse, and imaging studies. So all of this has to be incorporated, integrated together as one package and not just look at it individually and make decisions, right, only based on that. So it’s a good tool, it’s something to use, and we are learning more about it, and pretty soon, hopefully we will publish our results about that.”

Cora:

Dr. Tannir, there is news about monitoring levels of the biomarker CA-125 and renal medullary carcinoma and how it may help predict disease development. What do we know about CA-125 as a biomarker in renal medullary carcinoma?

Dr. Tannir:  

The CA-125 biomarker has been established as a good serological marker that you test in serum in women with ovarian cancer. So in women with ovarian cancer or suspected to have ovarian cancer, that blood test can be very valuable and elevated blood level of CA-125 in women with suspected ovarian cancer or established already women already diagnosed with ovarian cancer can provide information about the activity of the disease and response to therapy. So when a patient with ovarian cancer, for example, a response has, say, a debulking surgery and then the blood test is drawn, is tested after surgery the blood level will go down. You give them chemotherapy and the blood level goes down indicating that they’re responding. If they achieve a complete remission, complete response that CA-125 level could go down to undetectable level or normal range level as physiologic and women who don’t have ovarian cancer. Likewise, we use it in ovarian cancer to see if it’s rising, that the patient could be developing a recurrence of that disease. So it’s been very helpful in that regard.

And actually the pioneer this researcher, the physician scientist who led the initial work with CA-125 as a biomarker in cancer, was Dr. Robert Bast from MD Anderson. Now recently Dr. Msaouel and our team at MD Anderson looked at a battery, a panel of serology to really see if one of them is associated or could be linked to RMC and among a battery, a panel of several of these serological biomarkers. We found that CA-125 actually is a valuable blood test that we use to monitor RMC, not just in women like ovarian cancer, women with ovarian cancer, but in men and women with RMC the CA-125 could be valuable. Now, it’s not as they say panacea, it’s not like it’s if a patient has…the patient could have high tumor burden with obvious disease when you do CAT scans and MRIs and PET scans and other imaging studies.

But CA-125 may not be elevated but in many patients it can track the disease response to therapy that you are treating the patients with. And it could be valuable in that sense. But more recently we found that this could be also a relevant or a potentially relevant and important target to use therapy against RMC with that. So we are developing, Dr. Msaouel is preparing and hopefully we will launch this trial before the end of the year where we are using novel therapy based on that link based on that CA-125, whether this therapy will be more effective than chemotherapy, time will tell. So my activation tip on this is it’s good information to have, I encourage providers who treat patients with RMC at other institutions to test draw the blood order this test on their patients and see if in their patients it’ll be valuable.

It’ll be helpful to help them to track the disease. So that’s my activation tip is another valuable information to have, but it has to be interpreted in the context of other things in the context of how the patient is doing, whether they have symptoms that are improving or getting worse, and imaging studies. So all of this has to be incorporated, integrated together as one package and not just look at it individually and make decisions, right, only based on that. So it’s a good tool, it’s something to use, and we are learning more about it, and pretty soon, hopefully we will publish our results about that.

Lisa Hatfield: 

Okay. So, Dr. Shah, you have a patient that comes into your office newly diagnosed with DLBCL, maybe from their…or they’ve heard it from their primary care provider, they understand, they looked it up on the Internet, diffuse large B-cell lymphoma, they see the lymphoma, I would anyway, I’d see lymphoma, and I know it’s cancer. What’s included in your initial evaluation, how do you explain in basic terms to a newly diagnosed patient what DLBCL is? 

Dr. Nirav N. Shah: 

Yeah, great question, Lisa. I think that any time somebody gets that diagnosis with a cancer label on it, it’s incredibly overwhelming, and so what I try to do when I see my new patients is first simply just learn about them. How did this come about, what symptoms led to this diagnosis? Learn about their past medical history, which impacts how I might treat them and what options I’m going to give them, and sort of learn about who they are a little bit, learn about their family, what they do for a living, because I think those are important values to know about your patients, when trying to make a treatment decision.

What I try to explain to these patients is that DLBCL, yes, it is a cancer. Yes, it is, unfortunately, an aggressive cancer, one that can be very rapidly growing, but unlike a lot of cancers, it is a curable type of cancer, and I really try to highlight that like all cancers, unfortunately, not every single patient is cured with diffuse large B-cell lymphoma, but initially, I think there’s reason to have optimism and hope because the goal is, for me, when I meet a new DLBCL patient to provide a curative intent treatment approach for them.

As a part of that initial evaluation, we need to know more about where their disease is and in lymphoma. We often use a PET-CT, which is a special type of scan that sort of lights up areas that can be involved with lymphoma. In some cases, we do a bone marrow biopsy, although that is less indicated now because of how good the PET scans are, and then we talk about other testing, a lot of the chemotherapies can cause problems to your heart, so we often do an ultrasound of your heart to make sure it’s healthy enough to be able to tolerate some of the regimens that we consider for this disease, and then we talk about access in terms of how are we going to get the chemotherapy into the patient, and whether or not they would need a device like a port. But the main focus of the conversation is explaining the disease, teaching about the disease and focusing on that unlike other cancers, even stage III or IV diffuse large B-cell lymphoma is a curable entity, and the key is moving promptly getting the workup done in an efficient but complete manner and then initiating a treatment plan. 

Lisa Hatfield:

Right, thank you. And if you had one tip for patients when they first come in, what would you tell this patient that’s coming to see you in? 

Dr. Nirav N. Shah:

Yeah. I think my activation tip would be to learn as much as they can about this diagnosis and take notes, because I know that often patients in that first visit don’t really register everything. Just because they’re feeling overwhelmed.

 How is Multiple Myeloma Staged

Transcript:

So how is multiple myeloma diagnosed? The International Myeloma Working Group (IMWG) confirms diagnosis with both:

  • Presence of malignant plasma cells in the bone marrow at greater or equal to 10 percent or presence of extramedullary or bony plasmacytoma, confirmed with biopsy
  • CRAB features:
    • Calcium elevation: serum calcium greater than 0.25 mmol/L (> 1mg/dL) higher than the upper limit of normal or greater than 2.75 mmol/L (> 11 mg/dL)
    • Renal failure (or kidney failure): creatinine clearance less than 40 mL per minute or serum creatinine greater than 177 μmol/L (> 2 mg/dL)
    • Anemia: hemoglobin concentration of greater than 2 g/dL below the lower limit of normal, or a hemoglobin concentration of less than 10 g/dL
    • Bony lesions: one or more osteolytic lesions found on X-ray, CT scan, or PET‑CT scan
  • Ratio of involved/uninvolved serum free light chain ratio greater than or equal to 100
  • Clonal plasma cells in the bone marrow greater than or equal to 60 percent
  • One or more focal lesions found on MRI studies (measuring a minimum of 5 mm in size)

Dr. Elizabeth O’Donnell:

Testing really does depend a little bit on the stage at which your disease is found. In general, we use a very specific blood test that lets us know that there is clonal protein present. Remember, plasma cells are a type of white blood cell, and they make something called antibodies. We use a test called a serum protein electrophoresis, which is a blood test – an SPEP, we call it – that can tell us the difference between normal, healthy antibody and clone that are made from the plasma cells that we see in MGUS, smoldering, and multiple myeloma…once we identify that there’s a plasma cell disorder, then that can set in place a workup, depending on the amount of clonal, monoclonal, M-protein that we see.

So, sometimes that involves bone imaging. Historically that was a skeletal survey where we took lots of X-rays of your body. Now we have other tests we use. PET scans, CT scans, whole body MRIs. Sometimes it depends where you’re getting your treatment, and also it depends a little bit on your doctor’s degree of suspicion. 

 Lisa Hatfield:

So my myeloma was diagnosed using a scan. An MRI was done of my spine, and that’s when my doctor saw the plasmacytoma in my spine. Further testing indicated that I had something called kappa light chain myeloma. So a lot of patients will have regular tests done, blood work that may show anemia. I think if anybody has an indication of myeloma, further testing should be looked at. There’s something called a light chain assay, a normal CBC, a metabolic panel, a light chain assay was critical in my case, because all my protein levels were coming back normal. Some patients have an elevated level of protein in their blood. Mine was normal. So having all the standard blood work plus having the light chain assay done.

And then really the gold standard for diagnosing myeloma, unfortunately, right now is a bone marrow biopsy. It’s not fun. It’s not horrible. So for patients who are anticipating that, you can get through it. It will be okay. That is the gold standard for diagnosing the myeloma,  the type of myeloma, and then any cytogenetics related to that myeloma that help guide the therapy that you might be getting going forward.

Katherine:      

Let’s start by understanding what DLBCL is and how it progresses. How would you define DLBCL?

Dr. Kline:       

Well, diffuse large B-cell lymphoma is a malignancy of a normal counterpart cell called a B-cell, which is part of our immune system. Its job is to make antibodies, to help protect us from various types of infections. Diffuse large B-cell lymphoma, or DLBCL, initiates when normal B-cells acquire changes in their genetic machinery, like any cancer. And DLBCL is the most common form of non-Hodgkin lymphoma. We classify it as aggressive, as an aggressive lymphoma, which means if left untreated it tends to grow pretty quickly.

Katherine:      

How is it typically diagnosed?

Dr. Kline:       

Well, it varies. But like any cancer, a diagnosis requires some sort of a biopsy, either a surgical removal of a lymph node or a needle biopsy of a lymph node or another structure where the tumor seems to be growing.

Katherine:      

How does somebody know if they have DLBCL?

Dr. Kline:       

Well, there are certain symptoms that are more common amongst folks with DLBCL. And they’re not specific to DLBCL, they can be seen in other lymphomas, but they include symptoms like fatigue that’s unrelenting, unintentional weight loss, sometimes fevers, typically at similar times throughout the day, drenching night sweats, swollen lymph nodes, and then certainly pain in any area of the body that comes and doesn’t go. Those are some of the general symptoms.

Katherine:      

And how does the condition progress?

Dr. Kline:       

Well, as I mentioned, DLBCL tends to be an aggressive lymphoma, so sometimes folks will notice enlarged lymph glands that continue to grow and grow and grow. Sometimes they’re painful, sometimes not so much. DLBCL, it can really grow anywhere, so we think of it as a lymphoma and so involving lymph nodes, but DLBCL can grow in any organ, even outside of lymph nodes. And so it sometimes progresses locally, but it also can spread and start to grow in other areas of the body.

Katherine:      

And how is it staged, Dr. Kline?

Dr. Kline:       

Well, there’s a special staging system for all lymphomas that is somewhat similar to what folks might think of with solid tumors like a breast cancer, a lung cancer. But in other ways, it’s different.

The staging tools for DLBCL are really most importantly PET scans and CT scans, really PET scans and in some cases bone marrow exams or bone marrow biopsies. The PET scan is a very sensitive scan that uses radioactive glucose to identify very sensitively where in the body lymphoma might be growing, because lymphoma cells really preferentially prefer to use glucose as their primary energy source. So, they preferentially take up the radioactive glucose that’s given through the vein before the PET scan is taken.

As I mentioned, in some cases, a bone marrow test is also done, although less and less frequently. Which is good, because that’s a more invasive and uncomfortable test. And so folks who have early stage DLBCL that typically involves one lymph node group, like for example, a lymph node in the neck or several lymph node groups on the same side of the breathing muscle, of course you can’t see my breathing muscle here, called the diaphragm.

Those are stage I and stage II DLBCLs. stage III DLBCLs are those that involve lymph nodes on either side of the breathing muscle, so in other words, lymph nodes involved in the neck and then maybe in the groin area, where stage IV DLBCLs are those that involve sites outside of lymph nodes like the liver or the lungs or the bones.

Katherine:                  

What are the subtypes of DLBCL?

Dr. Kline:       

Well, that’s a good and somewhat complicated question. So there, probably most importantly, there’ve been two subsets, if you will, of DLBCL identified, and they really have to do with where along the normal maturation course a B-cell becomes lymphoma or where the DLBCL develops in that normal maturation course. Some DLBCLs arise from what we call germinal center B-cells, which are B-cells that are sort of just seeing their natural antigen or what they’re supposed to recognize.

And then there are DLBCLs that arise in more differentiated or more mature B-cells, and those are called activated B-cell type DLBCLs. So, there’s germinal center and activated, the B-cell type DLBCLs. And I don’t know that that’s super important for your listeners to know, but it is important because these two subtypes of DLBCL are driven by largely separate mutations or alterations in the DNA, and they also respond differently to initial treatment. There are other rare subtypes that involve specific mutations and genes like MYC and BCL2, and these are the so-called double-hit lymphomas. They’re officially classified as high-grade lymphomas, but they’re very similar to DLBCLs. There are other rare subtypes of DLBCL, for example, a type that comes on typically in young men and women called primary mediastinal B-cell lymphoma.

But I think for the sake of simplicity, the most common two subtypes are the germinal center derived and then the activated B-cell type of DLBCL.

Katherine:      

All right. That’s good to know, thank you. It helps us understand the disease a little bit better.

Dr. Kline:       

Good.
