- 0:01Welcome to Talking FACS, and thank you for tuning in to Cancer Conversations
- 0:06on Talking FACS, a podcast collaboration between the University of Kentucky
- 0:10Markey Cancer Center and the UK Martin-Gatton College of Agriculture,
- 0:15Food and Environment's Cooperative Extension Service.
- 0:17We will share with you the latest developments in cancer prevention,
- 0:21diagnosis, treatment and research from the experts at Markey Cancer Center,
- 0:26Kentucky's only National Cancer Institute designated Comprehensive Cancer Center.
- 0:31Talking FACS is hosted by the UK Family and Consumer Sciences Extension Program.
- 0:36Our educators share research knowledge with individuals, families,
- 0:40and communities to improve quality of life.
- 0:44Complex issues require more than one solution and more than one voice.
- 0:49Thank you for joining Cancer Conversations on Talking FACS.
- 0:52I am your host, Mindy McCulley, Extension Specialist for instructional support
- 0:56with Family and Consumer Sciences Extension.
- 0:58Today, we will explore multiple modality management and interdisciplinary collaborations in action.
- 1:06From research to practice and from the university to the community,
- 1:10this show highlights how combining methods and working across disciplines leads
- 1:16to more responsive, effective treatment.
- 1:18My guests are Dr.
- 1:21Ayman Qasrawi and Dr. Ruta Arays, both assistant professors of medicine with
- 1:28the UK Markey Cancer Center.
- 1:30Dr. Qasrawi, or Dr. Q, specializes in hematology, and Dr.
- 1:35Arays specializes in medical oncology. Welcome to you both.
- 1:39Thank you so much. Thank you. I'm so glad that you are here to talk about something
- 1:44that I haven't heard a lot about. And so I'm guessing it is a new concept for our listeners as well.
- 1:51So let's just talk about what this type of treatment means for people across Kentucky.
- 1:58I am a medical oncologist, and I mostly see skin malignancy patients,
- 2:03the bulk of which are melanoma patients.
- 2:05And for a very long time, we have not had a lot of great options for our melanoma
- 2:10patients, but within the last 10 to 15 years,
- 2:13we've been fortunate to have things like immunotherapy appear on the scene that
- 2:18have really helped a fair bit in making outcomes for those patients a lot better,
- 2:22even for those with fairly advanced or what we would call metastatic disease.
- 2:26However, in those patients, sometimes the therapies are not effective or they
- 2:31stop working at a certain point.
- 2:33In those situations, sometimes those patients have specific mutations that we
- 2:37could target with oral therapies that can sometimes be good,
- 2:41but not every single person has that.
- 2:43Only about half of the patients with melanoma have what's called a BRF mutation
- 2:47for which we have targeted therapies. So again, those patients are kind of in
- 2:52a tough spot if they don't have the mutation or even if those drugs stop working.
- 2:56So once we run out of those options, so as you can tell, not that many to begin with.
- 3:02It's a really difficult place for a patient to be. So we've been very fortunate
- 3:07that in the last two years, about two years ago, exactly at this point.
- 3:11Something called tumor infiltrated lymphocytes has been approved for the treatment
- 3:15of advanced melanoma that's refractory or progressive on the therapies that I just mentioned.
- 3:21It's a wonderful treatment, but it's kind of a big effort among many,
- 3:25many groups, many specialists, not just medical oncologists,
- 3:29but other specialties as well.
- 3:32And that's kind of what we're here to talk a little bit about. And that's where Dr.
- 3:37Q's portion is probably the bulk of what's so important about the multidisciplinary
- 3:43approach to getting this done.
- 3:45So Dr. Q, tell us a little bit more about this multidisciplinary approach that is targeting melanoma.
- 3:55Yeah. So first, I'm one of the physicians with the Division of Hematogenic Cellular
- 4:00Therapy with the University of Kentucky. So I mostly see leukemias from a procedure
- 4:07called the bone marrow transplantation.
- 4:09But I also foresee many of the cellular therapies for what we call solid tumors,
- 4:14because if we classify cancer,
- 4:16we generally classify it into solid cancers, such as organ cancers and skin
- 4:21cancers, as well as the liquid malignancies or the liquid cancers.
- 4:25So for my role, basically, when the product got approved, I had conversation
- 4:31with Ruta and basically we said we need to bring the therapy for our patients in the Commonwealth,
- 4:37especially that we didn't have many other centers in the state that offered the therapy.
- 4:43So we went through a long process with contracting, training, and creating...
- 4:49Guidelines for our center, and then ultimately when we got activated,
- 4:54we have started treating patients.
- 4:57Maybe six months ago, when we started treating the patients,
- 5:01we have treated maybe six, seven patients so far.
- 5:04So we had a good experience with the treatment so far.
- 5:07And as the time passes by, there's a lot of hurdles that we passed,
- 5:12but I think the process is getting much smoother.
- 5:14So from my perspective, you know, what happens is Ruta identifies a patient
- 5:20that they are a candidate for this kind of therapy.
- 5:23And I call this treatment, you know, as kind of like a science fiction because
- 5:27you're essentially utilizing the patient's immune system to attack the cancer cells.
- 5:32So the product is actually alive.
- 5:35It's live cells that we extract from the cancer cells.
- 5:38So what happens is we identify the correct patient by looking at a lot of variables,
- 5:45including making sure that they are, they have adequate organ function,
- 5:48they have adequate organ, you know, and they also have adequate.
- 5:52Psychosocial support. So we do a comprehensive evaluation.
- 5:57And after that, we will have one of our experienced surgeons evaluate the patient.
- 6:02And then what happens is we extract a part of the tumor.
- 6:06We extract actually almost a golf-sized part of the tumor. So we need to have an adequent tissue.
- 6:13The surgeons will really help us in identifying which site of disease we have to extract.
- 6:18And after that, we send the tumor to the company that manufactured the product,
- 6:25and then they extract that part of the, that's called the lymphocytes.
- 6:31The lymphocytes are part of your immune system that attack the cancer cells,
- 6:34and they normally attack infected cells, but in this situation,
- 6:38they attack the cancer cells.
- 6:39So this is how the treatment works, is utilizes the patient's immune cells that
- 6:45are attacking the cancers.
- 6:47They grow these cells in the lab, and then they ship the products back to us.
- 6:52And after they ship, they are shipped to us, then basically they are admitted to the hospital.
- 6:56They get a week of chemotherapy, and that chemotherapy is designed to basically
- 7:01suppress the patient's immune system, to allow for these immune cells to grow in the patient's cells.
- 7:08I always try to mimic it by, you know, your immune cells system is kind of a closed room.
- 7:14There is only a very limited space of how many cells they can grow.
- 7:18So when we deplete the patient's immune cells, then these basically infiltrating
- 7:23lymphocyte cells or the TELT therapy product will grow in your body.
- 7:28Then we use a very short protein called interleukin-2 to grow these cells in
- 7:34your body. and then the patients stay in the hospital for roughly seven days
- 7:37and then they're monitored closely outpatient once they are getting discharged.
- 7:42The reaction to this type of treatment? Is it better than, say,
- 7:47standard chemotherapy where you're depleting everything?
- 7:50It sounds like to me what we're trying to do is just deplete those cancer cells, not,
- 7:56everything that cancer patient might come across. Yeah, and melanoma is a tricky
- 8:02thing because it doesn't really respond to chemotherapy.
- 8:06So it's normally not a huge part of treatment.
- 8:09That's why we talk about the immunotherapy and the other drugs,
- 8:11because melanoma doesn't really respond to chemo.
- 8:14And I love how Dr. Q talks about it as being almost science fiction,
- 8:18because it's a great way of thinking about it,
- 8:22because what we're trying to do with this kind of complicated process is sort
- 8:27of train the patient's immune system to go after the melanoma when we think
- 8:32the immune system was not recognizing it very well before and allowing it to
- 8:36grow and kind of get out of control.
- 8:39So the chemo is kind of meant to deplete everything that they have, kind of create, and Dr.
- 8:46Q, correct me if I'm wrong, because this is definitely your arena, not mine,
- 8:50but just create the right environment for the till that we harvested and amplified
- 8:55to take root and grow so that the immune system kind of can become strong again against the melanoma.
- 9:01So we're sort of rewiring your
- 9:03patient's immune system to try to get it to fight the melanoma better.
- 9:09Immunotherapy that we treat melanoma with does that to an extent, but not this well.
- 9:14And these cells are coming from the patient's tumor itself.
- 9:17So it's kind of personalized medicine in a lot of ways because it is coming
- 9:21from them. It is not a product that's meant to fit everyone.
- 9:25It's meant to fit their cancer.
- 9:26So that's the other thing that makes it very unique and complicated.
- 9:31Like Dr. Q said, there's the process of harvesting the tumor itself,
- 9:35which requires usually at least a minor surgery, depending on the spot we're choosing.
- 9:39Sometimes it's a lymph node. Sometimes it's a spot in the lung where the melanoma has grown.
- 9:44But that's the part that we take out of the patient and try to go after those
- 9:48lymphocytes, those wet blood cells that are kind of enmeshed in the tumor.
- 9:52That theoretically when grown and strengthened should be able to fight it better
- 9:56so it's kind of it's a very unique process.
- 10:00That has been theoretically in the works for a very long time,
- 10:05and it's very exciting that it's finally approved for us to use.
- 10:08It definitely works better than conventional chemo. It works better than some
- 10:11of the things that we try for some of these patients that stop working.
- 10:16Taking the immunotherapy as opposed to traditional types of therapies,
- 10:22and it sounds like to me also then it might help to fight against recurrence
- 10:27because they've already got the antibodies in them.
- 10:30That is exactly what I wanted to say, actually. So with all the cancers that
- 10:35are stage four or spread, with quite limited exceptions, most of the time,
- 10:43specific with solid cancers,
- 10:45the chemotherapy, what it does, it can stop growing the cancer for a short period of time.
- 10:51Then the cancer cells can outsmart the chemotherapy and start growing in other ways.
- 10:56But most of the time, the treatment effect is for a short period of time and
- 11:00usually measured in months.
- 11:02Sometimes in years, but most of the time it is measured actually in months for
- 11:05most of the cancers, especially like aggressive cancers like melanoma.
- 11:09And as Ruta mentioned, the traditional immunotherapy, the responses are good,
- 11:15but not good in everyone and limited in some of the patients, as I mentioned.
- 11:20So the advantage when you actually train the immune system by giving live cells
- 11:26or live cells is the responses can last for a long period of time.
- 11:32And it is exactly what you mentioned.
- 11:34It's like having an infection in the past, right? And then you are immune for
- 11:38the rest of your life, right?
- 11:40So we're not there yet to the degree that people are immune for the rest of
- 11:44their life, but I think it's improving with time.
- 11:47The responses are not for everyone, but people who respond, they can have a
- 11:51maintained response for years. That's at least what we know.
- 11:55So in an era where patients fail immunotherapy, and then the chemotherapy works
- 12:01in maybe not more than one out of 10 patients, and if it works for a short period
- 12:05of time, and they're very toxic too.
- 12:07So this is a remarkable achievement that you can actually have patients who
- 12:11survive 40 years and historically speaking, they didn't have any options at that time.
- 12:16Is it possible that in the future we will have, you know, a vaccination if your
- 12:23family has a history of, say, of some type of cancer and then you can test for
- 12:28that and then get vaccinated against it?
- 12:31There's actually some studies in that right now.
- 12:35There's a melanoma vaccine study actually combining it with immunotherapy.
- 12:40I believe there's other vaccines in the works as well. So it's not too far-fetched
- 12:44that maybe someday something like that would be possible.
- 12:47Right now, I think we're kind of far from that specificity, being able to kind
- 12:51of pinpoint something that you have a family history of or something like that.
- 12:55But someday it might be because we're already working on those things as cancer treatments now.
- 12:59That's exciting. It is.
- 13:02I want to mention also like people, let's say, are being treated at another
- 13:07institution in the Commonwealth.
- 13:09And they read and they want to hear about me. I think it's very important that
- 13:14the referral to us, or Dr.
- 13:16Ruta and myself, is as quickly as possible whenever we think that the patients
- 13:21are not responding well to immunotherapy.
- 13:23You know, we're learning with time, obviously, and this is a fairly new program, as I mentioned.
- 13:28But what at least Ruta and I have learned so far is the patients who have little
- 13:34amount of disease, if you know what I mean, is if you think about it the same
- 13:38way with an infection, right?
- 13:39If you have a massive infection, then you need to intervene with antibiotics
- 13:44as quickly as possible for your immune system to function better.
- 13:49But if you have a little bit of an infection, then you might not need the antibiotics
- 13:52and your immune system can't take over very easily.
- 13:55So it's kind of exactly the same way. So if you have a lot of cancer cells,
- 13:59a lot of the time the immune cells might not have time to learn how to attack
- 14:04those cancer cells. So I think it is very important that these patients are
- 14:08referred and evaluated properly.
- 14:10In a timely manner. Absolutely agree with that.
- 14:14Melanoma can get out of control very quickly, as Dr. Qand I have both found.
- 14:21So as soon as progression is seen with a melanoma patient who has advanced disease,
- 14:29they should really start strongly considering this option and being referred
- 14:32to a center who can offer them TILs.
- 14:35And you mentioned that this is available at UK and at UofL, correct?
- 14:40Correct. In Kentucky, yes.
- 14:42Of course, we talk about screenings and that sort of thing. Is there a screening
- 14:47where somebody might be referred after that screening for?
- 14:52Automatically, or would it be something that they're referred after meeting
- 14:56with their other oncologist?
- 14:59Usually probably after meeting with their other oncologist, but it's mainly just monitoring.
- 15:05We always monitor disease that's advanced with scans, so either CT scans or
- 15:10PET scans, and at the first sign that the current therapy really isn't working,
- 15:15meaning there's growth through the treatment, they should probably be referred.
- 15:19Our guidelines suggest as soon as possible.
- 15:22Sometimes there's even testing done in the blood to see if you can find a little
- 15:26bit of those cancer cells already starting to come up.
- 15:29And some institutions are even referring when you're not even seeing the progression
- 15:33on the scans, but when you're seeing the cancer cells in the blood a little
- 15:36bit, just because, again, there's no such thing as too soon.
- 15:41In some of these situations, you really want to start the process in a timely
- 15:47fashion, even if at the time that they see us, they might not have a perfect
- 15:51site to go after for procurement.
- 15:52At least we can get a lot of the things we need to get done kind of out of the way because Dr.
- 15:58Q kind of alluded to the fact that it's a pretty intensive chemotherapy.
- 16:02Usually patients need to have pretty much perfect organ function.
- 16:05So there's a lot of testing that needs to be done to make sure that they're
- 16:08good candidates for this process and me identifying it as part of it.
- 16:13But, you know, patients actually meeting the criteria to get the treatment is
- 16:17definitely a big part of it too.
- 16:19And I would guess that there probably is a point where it's too far gone. Is that right?
- 16:25Unfortunately, yes. We've had a couple of those situations too where the burden
- 16:30of disease was just too massive to really make any difference with any of the
- 16:35treatments we had to offer.
- 16:37And again, melanoma, sadly, is something that can become aggressive and grow
- 16:41quickly, which is again why we're both emphasizing the time frame so much.
- 16:46Yeah, I want to emphasize, as Ruta mentioned, she said, you know,
- 16:50there is no early referral.
- 16:51Definitely, there is not super early referral, but there is a super late referral, unfortunately.
- 16:58And I want to mention, unfortunately, we had a couple of cases where the melanoma
- 17:04grew on us while we're waiting for the product to be manufactured.
- 17:07So that whole process can take five to seven weeks and sometimes longer.
- 17:12So during that time, the melanoma is going to continue to grow.
- 17:15And if it's one of those aggressive diseases, then if you already failed in
- 17:20therapy, then you don't have much options to control the disease while you are
- 17:24awaiting the product to be manufactured.
- 17:27That's why the most important is the critical timing of the referral for us.
- 17:33I am I'm just sitting here with my mouth open thinking about all the things
- 17:37that can happen and how this can make a real difference in the lives of those
- 17:42who have been diagnosed with an aggressive form of cancer that maybe there wasn't a treatment for,
- 17:49previously so I thank you both for your time and I thank you for your expertise
- 17:53and your willingness to keep looking for those things that are going to make
- 17:58a difference in the lives of cancer patients,
