[Dr. Chris Beck]:
Today, we're going to be talking about Y90. We have certainly covered this topic in the past, but interventional oncology continues to evolve. Today we're going to be discussing some of that evolution with two doctors who are on the front lines of interventional oncology.
I'm proud and excited to bring to you two very excellent interventional radiologists, Dr. Juan Jimenez and Dr. Tyler Sandow. Juan and Tyler, welcome to the show.
[Dr. Juan Gimenez]:
Thank you.
[Dr. Tyler Sandow]:
Thank you for having us.
[Dr. Chris Beck]:
Yes, I actually had a lot of superlatives I was going to throw in there because it was like a big deal. What some of the BackTable listeners don't know is like all three of us right here, these are interventional radiologists who work in New Orleans. There's a lot of talent out of two of the three people here. I was excited.
[Dr. Tyler Sandow]:
Yes, it's you two. I'm just lucky to be involved.
[Dr. Juan Gimenez]:
Yes, absolutely.
[Dr. Chris Beck]:
Yes, right.
[Dr. Juan Gimenez]:
I feel like we've made it, we are on BackTable podcast. It's all downhill after this.
[Dr. Chris Beck]:
Yes, this is the pinnacle.
[Dr. Tyler Sandow]:
When do I get one of the sweatshirts? That has been a dream of mine for five years.
[Dr. Chris Beck]:
Actually, now you say that, I'll drop it off at your house.
[Dr. Tyler Sandow]:
Thank you.
[Dr. Chris Beck]:
I got a lot of hoodies. I got a large for both of you guys.
[Dr. Tyler Sandow]:
Perfect.
[Dr. Juan Gimenez]:
Yes.
[Dr. Chris Beck]:
I'll drop them off at Tyler's house.
[Dr. Tyler Sandow]:
Awesome.
[Dr. Chris Beck]:
All right. How about this, Juan, will you just go ahead and introduce yourself? Tell us a little bit about the practice and then we'll jump over to Tyler.
[Dr. Juan Gimenez]:
I'm Juan Jimenez, originally from Argentina. I moved here about 23 years ago and did all my training at Oxford. I've been in New Orleans for most of the time. I went out to fellowship. I came back two years later. I have had the pleasure to work with Tyler ever since. It's been great. We're 100% interventional radiologists. We do a ton of high-end work or what we consider high-end. I guess that's about it. I’ll let Tyler go ahead.
[Dr. Chris Beck]:
That's a very modest run-through of y'all's practice. All right, Tyler, tell us about yourself, your training, and about the practice.
[Dr. Tyler Sandow]:
I was thinking about this the other day. You and I have known each other for almost 10 years. Actually, it's been over 10 years. No, 2008. I remember when I was a first-year med student, you were a fourth-year med student. We had some fun times together.
[Dr. Chris Beck]:
I was such a prick.
[Dr. Tyler Sandow]:
Oh you were fun, man.
[Dr. Chris Beck]:
I was such a prick.
[Dr. Tyler Sandow]:
We had a good time.
[Dr. Chris Beck]:
Thank you, Tyler.
[Dr. Tyler Sandow]:
And then we wound up in New Orleans together only for you to leave me. I did my residency in New Orleans at Ochsner. I got abused by Juan for a solid couple of years after he came back. I learned a lot. I learned how to handle a lot of stuff and then went on to a fellowship to try to mimic what I wanted my future practice to be at Georgetown, knowing that I was coming back to Ochsner. Then, I've been here ever since. I’ve probably been on staff about five and a half years now. It's been a good time. It's been great. I'm happy to be back with you guys.
(1) Building an HCC Practice
[Dr. Chris Beck]:
Very nice. All right. Now, I really want to hear about the practice, because to just say you guys do some high-end work is an understatement. When you talk about just the day-to-day, we'll get into the interventional oncology. I just know from these guys, presenting it to my board, and from the cases y'all show me on your cell phones that it's the real deal. This is the absolute in the trenches. I guess you can call it kind of academic, but more balls to the wall, private practice, blowing and going right.
[Dr. Tyler Sandow]:
Yes, I would say we're a bit hybrid is probably the best way to call it because we don't – I'm jealous of some of these academic places where we hear that they do a couple high-end cases and then they go home, by like three or five o'clock. I feel like Juan built a monster, and now we're stuck trying to keep that monster going. I would say on a nice day, an easy day, we probably do about 20-25 cases between two or three IR staff. On a rough day, it's somewhere between 30 and 40.
We have an incredible team that we work with, nurses and techs that can turn over rooms and flip rooms fast. When we're doing those cases, they're not just abscess drains. It’s complex portal vein recans, TIPS. We do incredible biliary work, biliary scopes. Then on the flip side, our oncology volume is insane. Again, I think the majority of that credit goes to Juan and some of my predecessors for the product that they have built. Man, we probably do – I would say if we're not doing three or four mappings or deliveries on a day, it's a slow day for us. It's the monster that Juan built.
[Dr. Juan Gimenez]:
I was going to say, Tyler likes to give me a lot of the credit, but this is a team sport. It takes a lot of people to get this going and get it running. I think we got to give a shout-out to one of our old partners, Vijay Ramalingam. I would say our predecessor Vijay, Tyler and I did a good job getting the practice started. It was easy for us to come in and take it to the next level. We are lucky in that we work at one of the biggest transplant centers in the country, which brings a lot of people to our hospital. We're also one of the tertiary referral centers for the region as well.
On top of everything that Tyler said, we also have a growing practice when it comes to, even bread and butter stuff, GU, dialysis. We're going to get a little bit more into PAV. One or two of our newer colleagues are starting to grow and expand all of the venous side of the practice as well, including the reconstructions, IVC filter retrievals, and things like that.
[Dr. Chris Beck]:
Is there anyone else that helped build the Ochsner way that paved the way for you guys?
[Dr. Tyler Sandow]:
Yes, I think we definitely have to highlight when we talk about our predecessors, David Kirsch, Dan Devon, those guys laid the foundation for building local regional treatment at Ochsner, and because of the work that they've done and the presence that they established at our tumor boards, we've been able to build on those pillars and grow the practice the way that we have.
[Dr. Juan Gimenez]:
Yes, to Tyler's point, we wouldn't be here without them. They set the groundstone for everything that's happened since.
[Dr. Chris Beck]:
Very nice. I've just been texting with Ricky and Tim from TheraSphere. I'm guessing you guys probably don't keep up with this thing, but according to Ricky and verified by Tim, you guys have had more Y90 deliveries in 2023 than every other institution in the US.
[Dr. Tyler Sandow]:
It's what we hear.
[Dr. Chris Beck]:
Not that anyone's keeping track, but I'm just trying to paint a picture that we're talking to two guys who are doing a lot of Y90.
[Dr. Tyler Sandow]:
We do a little bit. We do a pretty fair amount.
(2) Adapting to Liver Transplant Regulation Changes
[Dr. Chris Beck]:
Okay, yes. We're going to talk about HCC. We can get a little bit into metastatic disease, but I wanted to talk about how Ochsner got to where you’re at because we're going to be talking about Y90, but obviously, that's not the only game in town for modality of treating HCC. Previously, I know that you guys were using resin but made the jump to glass. I was interested in why, and when looking back, in any pluses, or minuses.
[Dr. Juan Gimenez]:
Yes. I feel like it was all like the perfect storm, right? Around 2018 or 2019, we had several things happen. Vijay joined us in about 2017, and he really came in and upped our ablation game. It's one of the things he does really well, and he really pushed the envelope. When you also look at what was happening around that time, Premiere came out which was a new I guess way of looking at bridging HCC.
Around that same time, the organ allocation rules for transplant changed. Before all of this, it would take sometimes three weeks to a month for some of our patients to get transplanted, and now everybody had to wait at least six months to get a liver. We had to start thinking about if we needed to change not only with all of this new data coming out, but also with all of the changes that were going to affect our practice. We did realize that we had a pretty good working system. Everybody was getting TACEd, everybody was getting transplanted.
I guess there was a little bit of a resistance to trying to change our process. Tyler had an excellent relationship with transplant surgeons, and because of that, they trusted him and they confided in him. When we tried to implement some of these changes, there was not that much of a pushback. I think he was key in us being able to change our paradigm for treatment of these patients. I would say, little by little, as we changed, our results spoke for themselves. Then it just became, it was just simple. Tyler, what do you think?
[Dr. Tyler Sandow]:
I was going to say, to add to Juan's point, for a decade, we were – Ochsner, I should say, I shouldn't say we because this is a transplant thing, but Ochsner was the largest transplant center, year over year, for a solid decade. They did more liver transplants than any other place in the country. We didn't need to change at that point. TACE worked well because all we had to do was bridge to a certain point. Then they got transplanted in several weeks.
Then when you change the allocation scheme and now to get exception points, you’ve got to sit for six months, and it was Juan's pushing. He was like, it's time for us to change because we watched a few patients. By a few, I should say we started to notice a trend. We watched some patients start to progress or it was harder and harder to keep these patients stable or bridged on the transplant list. That was a big impetus to change. It was Juan's pushing that did it. For the longest time, man, when you're doing 250 livers a year, and you can turn and burn, we didn't need to. Things changed, so we did.
[Dr. Chris Beck]:
I do want to talk about the different modalities that you'll work through and your algorithm, so when you settle on Y90 and how you think about delivery. One of the things I wanted to talk about is referral patterns. Are all these patients coming through the transplant system or are some of them coming for oncology? I want to know, how does everyone get sent to you guys? Then once you put them into the IR process, what does that look like?
[Dr. Tyler Sandow]:
It used to be that it only came through our liver conference, our multidisciplinary transplant liver conference, because a lot of these patients with HCC would either have underlying cirrhosis and they would be referred by hepatology, or entered into the conference via hepatology for transplant eval. As we grew, as the conference grew, we started to notice that we had quite a few patients with more aggressive tumor burden, infiltrated disease. We had more of a buy-in from oncology. Now our referral patterns come from oncology, hepatology, transplant, and then we catch everything you can imagine across the Gulf Coast.
Anybody with HCC tends to get referred through the conference. Juan, you might have more to add to that, too.
[Dr. Juan Gimenez]:
Not much, I think you summarized it well. At the end of the day, I think our practice is a multidisciplinary approach and it's not only for HCC but also for metastatic disease, neuroendocrine. We truly believe in the value of all our colleagues and specialties to come to a table and work together to give the patients the best outcome. To Tyler's point, hepatology, oncology, surgeon, transplant, all of us participate. Every patient gets run through a conference, and the decisions are made collectively for the best outcome for the patient. Sometimes they come to us. Lately, we've been working very closely with oncology doing some of the combination therapies to treat these patients.
(3) HCC Practice Workflow
[Dr. Chris Beck]:
Okay, once they get plugged in with you guys and they've been through MDC, they get seen in clinic, labs, imaging. Take us through the process of getting your patients ready for what may end up being a procedure.
[Dr. Tyler Sandow]:
We have incredible APPs. I think we should plug everybody that is involved in our entire team in this process. We have some incredible APPs and schedulers that help coordinate the care of these patients. What tends to happen is after a liver conference, we try to get them scheduled in clinic that week or the following week. Then Juan pushes us to maintain the protocol. I can let him talk to that a lot more. We have an algorithm and a protocol for how we evaluate these patients and how we get them set up for treatment.
[Dr. Juan Gimenez]:
It's pretty straightforward. APPs come to conference with us. We, interventional radiology, run these conferences. We review all the imaging, make all treatment recommendations as it pertains predominantly to IR. Sometimes the recommendation is, hey, this patient is systemic. That's coming from us, which I think is very valuable to the entire team. APPs sit with us during conference. They know exactly what happens. The moment conference finishes, we just set them up for clinic. The entire team notifies the patient and then we move on.
We try to stratify patients, so the ones that tend to be more advanced jump to the top of the list, and we try to get them in for procedures sooner than somebody that's at an earlier stage has a single tumor and can wait a little bit longer. Having labs and imaging, within 30 days is very important. We typically don't biopsy these patients. If they have HCC imaging criteria, we will avoid it. We've had several patients that have had biopsies. We ended up seeing recurrences along track or track seating, I should say. Then they drop out of the transplant list. We don't favor biopsy unless it's absolutely necessary.
If it is somebody that we suspect has HCC and they have, let's say, an elevated AFP but they don't meet criteria, we'll map and biopsy them at the same time, effectively saving them one appointment. You avoid delay of care by doing that. To Tyler's point, everybody, not only within the transplant, hepatology, and oncology teams but even our teams, like he said, our APPs and our schedulers, everybody's plugged in, and it's become a very well-oiled machine to try to get patients seen and treated as soon as we can.
[Dr. Chris Beck]:
You've given us a rundown of the process, Juan. If you had to give advice to someone who's either at a big academic center or someone who's just on the cusp of forming a well-oiled machine, what were some of your big unlocks that led for increased throughput, or making sure the right patients were prioritized? I would always say MDC is at the core of that, but I just want to hear what you guys think.
[Dr. Juan Gimenez]:
It's ownership. You literally have to own every step of the way, particularly when you're first starting. I think there's this belief that IR just does what comes to them. Trying to change that thought process in people saying, look, I want to be an active participant in the patient's care. I'm going to take them from the beginning, own their imaging, see them in clinic. We'll take this patient and make sure that everything that pertains to us, we'll handle without you having to worry about it. I think that's been key.
We see a lot of sometimes particular patients come from other facilities or other regions. A lot of clinicians don't necessarily feel very comfortable dealing with HCC. For us to be able to bring them into our system and help them navigate that, has been very important and very good for patient care.
(4) Determining Optimal HCC Treatment
[Dr. Chris Beck]:
All right. Moving on, so past the workup, you're getting them ready for some kind of treatment. There's not just Y90. Can you guys talk about which patients end up with which treatments? We can exclude systemic therapies, but which treatments that you guys offer?
[Dr. Tyler Sandow]:
I'll say we follow the BCLC algorithm as closely to the T as possible. If there's a patient that meets criteria for ablation, then we're going to ablate it unless we feel like it's a high-risk ablation and Y90 made more sense. We go for, our process is, regardless of whether or not they're going to transplant, we want to give them, even if it's a bridging strategy, we want to give them the most durable outcome possible. I think if you look at the BCLC structure, the durability comes from ablative modalities, whether that be Y90 or ablation.
The majority of the patients that we see either have pretty advanced cirrhosis, so if they weren't transplant eligible, our surgeons don't necessarily want to take an advanced cirrhotic to resection. That's where an alternate ablated modality that probably provides just as durable of a result makes the most sense.
We have, and we can dive in, at some point, we can talk about the research we do. We've been tracking outcomes on these patients for a very long time. We've noticed trends in our outcomes to allow us to alternate a little bit, or deviate, I should say, a little bit away from a purist BCLC scheme. We don't necessarily ablate everybody anymore because we've noticed trends in our data that would probably push us more towards an intra-arterial therapy, and we know that Y90 is probably going to be the best for those. We can talk about that later, too, if we have time to talk about our research stuff.
[Dr. Chris Beck]:
Anything to add on that, Juan? Specifically, I guess one of the things I wanted to paint is, you guys don't shy away from ablation. You’re more than happy to ablate. I think one time you even told me sometimes patients are candidates for both, like you may ablate, then something else may be a better candidate for intra-arterial therapy.
[Dr. Juan Gimenez]:
Yes, I think at the end of the day, we want to provide them a complete response with whichever modality works best. To Tyler's point, being able to look at our data has allowed us to fine-tune the way we cater to every patient, but at the center of it is the BCLC algorithm.
[Dr. Chris Beck]:
Okay, what about anything else for intra-arterial, like is TACE on y'all's treatment list anymore, or TACE ablay, anything else?
[Dr. Tyler Sandow]:
I would say 2% of the time might be what we might TACE now. That's going from a place that was maybe 98% TACE six years ago. We'll TACE very rarely, only in patients that probably maxed out their lung dose for Y90, or have lung shunts that are through the moon, so we wouldn't be able to get a good treatment dose in. Those would be our candidates for TACE. Back to ablation, we're not afraid of ablating. We owe Vijay, he pushed us hard to do ablation. He made us ablate on the heart, he made us ablate at the hilum, he made us ablate on the IVC. We're not afraid of anything, and that's because he pushed us to do it. He helped us up our game when it comes to ablation. Regarding TACE, man, it's rare. It's I think high lung shunts or patients that don't have any more Y90 options available.
