What if prostate cancer treatment weren't months of daily radiation—but five ultra-precise sessions guided in real time by MRI? Today, Dr. Michael J. Zelefsky (Professor of Radiation Oncology, NYU Grossman School of Medicine) explains how MRI-LINAC and adaptive planning are redefining accuracy, reducing side effects, and personalizing care. A pioneer behind IMRT and image-guided radiotherapy, Dr. Zelefsky breaks down SBRT vs. IMRT, protons vs. photons, HDR brachytherapy, when to add hormone therapy, and how genomics + AI are shaping what's next.In this conversation, Dr. Zelefsky charts the evolution from long-course radiation to short-course SBRT with outcomes comparable to 7–9 week regimens—thanks to precision imaging and planning. He clarifies where IMRT ends and SBRT begins, why protons haven't shown superiority over photons in prostate cancer, and where HDR brachytherapy (Ir-192) shines—especially as a boost in higher-risk disease. We dig into dose equivalence (why 5×8 Gy can match ~80–90 Gy long-course), risk-based treatment + ADT duration, and how Decipher/Artera scores can refine decisions. Most exciting: MRI-LINAC with continuous motion monitoring keeps the prostate in a virtual “bullseye,” enabling whole-gland treatment with focal boosts today—and potentially true focal therapy tomorrow as biologic imaging and AI mature.Time-Stamped Highlights00:00 – Welcome 02:00 – Why Dr. Zelefsky's work is so respected; career arc and impact04:00 – What changed: CT/MRI planning → 3D-CRT → IMRT → SBRT12:45 – IMRT vs. SBRT: definitions, session counts, who gets what19:10 – Energy sources overview: photons, protons, brachytherapy20:30 – Protons vs. photons: evidence, indications, cost, access24:00 – HDR brachytherapy (Ir-192) as a temporary “in-and-out” boost28:00 – Dose logic: why 5×8 Gy (~40 Gy) ≈ long-course 80–90 Gy29:30 – Risk groups (low/intermediate/high) and when ADT is crucial33:00 – ADT durations (6–36 months): what trials actually showed37:00 – Genomics (Decipher/Artera): resolving risk discrepancies39:00 – What MRI-LINAC adds: real-time adaptive planning43:00 – Continuous Motion Monitoring (CMM): beam stops if target moves47:00 – Treat whole gland + boost the DIL (FLAME study approach)49:00 – Toward focal therapy with better biologic imaging + AI54:00 – How to choose: values, side-effects, lifestyle, comorbidities01:01:00 – Final guidance: don't be overwhelmed—multiple good option

In this panel discussion, UROONCO RCC associate editor Dr. Teele Kuusk talks to EAU RCC guidelines panel members Prof. Axel Bex and Assoc. Prof. Saeed Dabestani on the 2025 updates in the EAU Guidelines for renal cell carcinoma (RCC). Their conversation includes the impact of KEYNOTE-564 on adjuvant therapy, recommendations for stereotactic body radiotherapy (SBRT), surgical approaches, systemic therapies for papillary RCC, and new trial data. They also share insights into ongoing research on liquid biomarkers and perioperative treatment strategies. 

In this episode of the Dr. Geo Prostate Podcast, we welcome Dr. Jonathan Lischalk, Director of Genitourinary Cancers at MedStar Georgetown University Hospital and former Medical Director at NYU's NYCyberKnife Center. Dr. Lischalk breaks down the evolution of radiation oncology and how cutting-edge imaging and targeted SBRT (Stereotactic Body Radiation Therapy) are reshaping prostate cancer treatment.We explore how imaging advances like MRI and PSMA PET scans are enabling unprecedented precision, the future of genetic-based personalization in prostate cancer therapy, and why fewer, more focused radiation sessions might soon become the new standard. From understanding the biology of radiation dosing to upcoming trials eliminating ADT in select patients, this is a must-listen for anyone looking to stay informed on the forefront of cancer care.

Last week the Edinburgh Cancer Centre begun treating prostate cancer patients within the framework of the so-called Precision Study. Patients receive only three radiation doses, with the Raypilot System used as a complement to ensure accurate motion control during treatment, thereby minimising potential side effects. The aim is to demonstrate that three sessions work as well as five in terms of both cancer eradication and the degree of side effects. The Pace-B study*, published in 2024, showed that SBRT** with five radiation sessions is just as effective in curing cancer as traditional treatment involving 20-40 sessions. The Precision Study aims to further streamline treatment while reducing side effects and improving patient convenience. The treatments in the study are carried out using the Raypilot System, which enables real-time monitoring of organ movement. This system allows for urethra-sparing techniques and tighter radiation margins - factors that both improve targeting accuracy and reduce the risk of side effects. Prostate Cancer Treatment Aiming for Improved Quality of Life The study includes 100 patients across multiple clinics in Europe and the US and is led by Professor Duncan McLaren at the Edinburgh Cancer Centre in Scotland. His aim is to make prostate cancer treatment more comfortable for patients and improving their quality of life post-treatment. "The goal of the Precision Study is to ensure that treatment with three radiation doses does not lead to greater side effects than those observed in the Pace-B study. I am confident that we can demonstrate effective cancer treatment with less side effects," says Professor McLaren. A Collaborative Effort for Improved Healthcare The study was initiated by researchers at various clinics using the Raypilot System. "Our customers are interested in developing and improving healthcare, always with patient quality of life in focus. At the same time, healthcare providers across the Western world are striving to reduce treatment times and enhance both quality and efficiency. This study could contribute to such progress, benefiting all stakeholders - healthcare providers reduce costs while improving care, and patients gain a better quality of life," says Thomas Lindström, MD at Micropos Medical AB, the company behind the Raypilot System. The first conclusions from the Precision Study are expected within one to two years, followed by a further five years of patient follow-up before final results can be presented.

This week on BackTable Urology, Dr. Aditya Bagrodia (UCSD), medical oncologist Dr. Rana McKay (UCSD) and radiation oncologist Dr. Shankar Siva (University of Melbourne) discuss the growing role of radiation therapy in kidney cancer treatment. --- SHOW NOTES Shankar first explains the original historical studies that provided evidence of the limited efficacy of low dose conventional radiation therapy (RT) in treating kidney cancer. However, he and Rana discuss how stereotactic body radiation therapy (SBRT), a newer technology which delivers a higher dose per fraction more accurately, has shown better outcomes in clinical trials than conventional RT. They also explain the associated risks with SBRT and how neoadjuvant therapies can be combined with radiation. They also consider the use of SBRT in bulky tumors and those with IVC thrombus. All three doctors agree that radiation therapy needs to be incorporated into a multimodal approach to kidney cancer. They also discuss the potential of radiation therapy in the cytoreductive setting and its role in delaying systemic therapy in patients with oligometastases. Finally, they explore the possibility of using PET imaging to detect oligometastatic disease. Although prostate-specific membrane antigen positron emission tomography (PSMA PET/CT) imaging is mostly used to stage prostate cancer, other solid tumors like renal cell carcinoma (RCC) may also express PSMA. For this reason, they agree that a next generation PSMA PET/CT equivalent for RCC could be revolutionary. Lastly, they predict what the future of RCC could hold by examining newer therapies, such as radioligand therapy and cyberknife. --- RESOURCES Kidney Cancer Association: 2023 International Kidney Cancer Symposium (Nov. 9-11) https://www.kidneycancer.org/ikcs/2023-ikcs-north-america/ Decipher by Veracyte https://decipherbio.com/ WellPrept https://wellprept.com/

Dr. Aggarwal: Hello and welcome to this Cancer.Net Research Round Up podcast. Today, we will be talking about the latest research from the Annual Meeting of the American Society of Clinical Oncology from June 2023, and I'm joined today by 2 experts in the field of lung cancer. Before I introduce them, I'd like to introduce myself. I'm Dr. Charu Aggarwal. I'm an associate professor for lung cancer excellence at the University of Pennsylvania's Abramson Cancer Center. I'd now like to introduce Dr. Melina Marmarelis. Dr. Marmarelis: Hi, so happy to be here. I'm Melina Marmarelis. I'm an assistant professor at the University of Pennsylvania and the medical director of the Penn mesothelioma program. Dr. Aggarwal: And Dr. Kristin Higgins. Dr. Higgins: Hi, everyone. I'm Kristin Higgins. I am a thoracic radiation oncologist at Winship Cancer Institute of Emory University. I'm a professor and vice chair for clinical research for radiation oncology. Dr. Aggarwal: Fantastic. So today, we'll talk about relevant research as it applies to practical implications in the clinic for practitioners, but most importantly, patients with lung cancer. I'd like to start off by discussing 2 key studies, and I would love for perspectives from our faculty here. The first study I want to highlight is the ADAURA trial. This is a trial that has already sort of changed practice in most recent years when the study was presented at the Annual Meeting of the American Society of Clinical Oncology in 2020, but we have new updates on this study as of 2023. So, in brief, this was a study that looked at the value of administering an oral pill called osimertinib that is a tyrosine kinase inhibitor against the EGFR, or the epidermal growth factor receptor, in patients with non-small cell lung cancer. We know that non-small cell lung cancer is quite a heterogeneous disease with some subsets of patients having mutations that may render them increasingly sensitive to the effects of these tyrosine kinase inhibitors. In fact, these pills have been used in the metastatic setting for several years based on an improvement in overall survival. What the ADAURA study tried to do was ask the question if this pill would add an incremental advantage after receiving curative-intent surgical resection in those with early-stage lung cancer. So this study enrolled patients with stage IB to IIIA non-small cell lung cancer after surgical resection and focused only on those patients that had sensitizing EGFR mutations with EGFR exon 19 deletion or L858R mutations. Patients could receive chemotherapy after having the surgery and then were basically randomized into 2 groups, one of whom received osimertinib at a dose of 80 milligrams once daily for a total of 3 years. Patients were followed up for recurrence. We already know from the earlier results that patients who received osimertinib had a better chance of delaying the recurrence of disease. However, what we found at the Annual Meeting this year is that the administration of this osimertinib also improved overall survival, which is really what we all look for in the oncology world. If you're administering a therapy, especially for a long duration, we want to be able to see a survival benefit, and that's what we saw. In fact, in patients who received osimertinib, there was a 49% less likelihood of dying from lung cancer compared to those who did not receive osimertinib. This, I think, is practice-affirming. It may not be practice-changing because some of the practitioners started using osimertinib after its FDA approval in December of 2020, but I think it just confirms our practice as it delivers an overall survival advantage in these patients. One thing that's increasingly important is to identify patients who have this mutation, so now we have efforts underway locally as well as nationally to perform molecular genotyping on all patients with lung cancer so that we can adequately and appropriately treat those with early-stage lung cancer following curative resection or following surgery. Melina and Kristin, what are your thoughts? Dr. Marmarelis: Well, I think these results are really important because it did, as you say, affirm kind of what we're already doing, but I think the most convincing part of this for me is the prevention of spread of disease to the brain. This is not comparing osimertinib after surgery versus osimertinib ever, which I think is a difficult part about interpreting this trial. But I think the fact that it prevented disease from going to the brain is really meaningful to everyone, to patients, to the physicians that are caring for them, so I think that's a really important endpoint. Dr. Higgins: I agree with Melina. I think this is really exciting for our patients. It's exciting to have more treatment options for early-stage lung cancer. I think patients that are diagnosed with early-stage lung cancer are highly motivated to do everything they can to improve their likelihood of being cured. So I tend to have a lot of conversations about side effects and toxicities with patients that have questions and are sort of wondering how it will affect their quality of life, and of course, that is an important piece of it because patients that do have curable lung cancer are probably starting off with a better overall quality of life, but I think generally speaking, our patients have tolerated it well. I'm also kind of excited from a radiation oncology point of view. We treat patients with stereotactic body radiation therapy [SBRT] that are medically inoperable. And we have another trial with a cohort looking at osimertinib for those patients that have EGFR mutations, too, and that's ongoing, again, applying the same concept of trying to really use these SBRTs that work really well in the advanced setting, moving them into earlier stages of disease to help us care for more patients. So overall, I think it's really exciting, and I think it's a huge win for the clinical research community. Dr. Aggarwal: Well, that's wonderful. And I think this certainly advances the field as this is the first targeted therapy approved for patients with early-stage non-small cell lung cancer. I should add that AstraZeneca, the company that makes this drug, has provided institutional research funding to my institution, and I also serve as an advisor to them, but I was not involved personally in the research of this clinical trial. I'd like to move on but stay within the field of early-stage lung cancer and talk about another study called the KEYNOTE-671 study, and this is important because it really applies the idea of using immunotherapy before and after surgical resection in patients with early-stage lung cancer. Just to give a little bit of background to our listeners, we now have 3 approvals for the use of immunotherapy in patients with early-stage lung cancer. Two of those are in the adjuvant setting, meaning that if a patient undergoes surgical resection or surgery for early-stage lung cancer, they can receive either atezolizumab or pembrolizumab following that surgery, and that has been shown to improve outcomes in terms of reducing the chances of recurrence. We also have another approval, which is the third approval in early-stage lung cancer, where 3 cycles of chemotherapy and immunotherapy are administered prior to surgery, also called as the neoadjuvant chemo-immunotherapy approach. This drug that has been approved in combination with chemotherapy is nivolumab, and this approval came from a clinical trial called CheckMate 816 that showed both that patients who received this neoadjuvant chemo-immunotherapy approach had a higher proportion of patients who had complete response or pathologic complete response in their tumors at the time of surgery and also showed that the chances of the disease coming back after surgical resection was much lower amongst those that had received this intervention. The current study, the KEYNOTE-671 study, builds upon this concept and adds both a before-surgery intervention as well as an after-surgery intervention. So what this study did was it enrolled patients with early-stage, stage II to IIIB non-small cell lung cancer, and patients in the intervention arm received 4 cycles of chemotherapy in combination with pembrolizumab, underwent surgery, and then received immunotherapy with pembrolizumab for up to 13 cycles. Patients in the control arm received only chemotherapy prior to surgery and then placebo for up to 13 cycles after. This was a large study with about 786 patients randomized, and what we found was that those patients that received the intervention had a much higher likelihood of remaining disease-free or event-free following surgical resection as well as in the early analysis, an improvement in overall survival with about a 27% reduction in the risk of death. So I do think that this is the first study that shows us that use of both neoadjuvant as well as adjuvant. So sort of this perioperative approach of using immunotherapy before and after surgical resection can actually lead to improved outcomes. This is ultimately what we want for our patients, improvement in overall survival, improvement in cure rates, etc. The study has been silent on the use of radiation therapy, although it has gone into details in terms of the kinds of surgery that was done. Kristin, what are your views about this? Dr. Higgins: I think postoperative radiation after resection for non-small cell lung cancer has sort of started to fall out of favor because of the Lung ART trial that was published in Europe, a randomized phase III trial that showed no differences in disease-free survival or overall survival. And that's not to say that there aren't more study questions on ways to give it safer and ways to incorporate radiation in with the chemo-IO approach, and there are some novel ways to do that, and we're going to see some data presented at the World Lung Cancer Conference looking at some of those novel approaches. But standardly, when patients receive neoadjuvant chemo-immunotherapy followed by surgery, we typically would not offer radiation. There are instances, though, when patients have positive margins, for example, and in that situation, it's sort of a discussion on a case-by-case basis. But ideally, we're hoping that most of these patients that go to surgery are able to get a complete resection, and that's really the key component of the decision-making for deciding if patients are eligible for this approach. Dr. Aggarwal: I agree. Melina, any additional thoughts on this trial? Dr. Marmarelis: I think it's an exciting trial for the reasons that you mentioned. I think it does bring up a number of questions about whether both neoadjuvant and adjuvant immunotherapy are needed. I tend to like the idea of having immunotherapy present when the tumor is present before surgery, so I like kind of having that on board, but I think we still don't know which is more important. Dr. Aggarwal: So it certainly raises many more questions, which hopefully will be answered in the future. KEYNOTE-671 trial was conducted by Merck that produces the drug Keytruda, or pembrolizumab. We have received institutional research funding for other trials. I was not personally involved in this clinical trial. I do serve as an advisor for Merck. I think we'll bring you more research from the ASCO Annual Meeting. And I'll turn it over to Dr. Marmarelis to discuss some more exciting research. Dr. Marmarelis: Thanks, Charu. So perhaps it's not surprising that one of the exciting things I picked from ASCO has to do with mesothelioma. And I just want to put into context a little bit about why this trial was important. This is IND227. It was a cooperative group trial done across Canada, France, and Italy, and this was chemotherapy plus or minus pembrolizumab in patients with pleural mesothelioma that did not undergo surgery. So this was their first treatment, and they were not undergoing surgery. And the reason this trial was important is that in the last few years, we had results from CheckMate 743, which was looking at IPI/NIVO, so a combination of immunotherapies versus chemotherapy. And there was an improvement in survival for those that received double immunotherapy, and that improvement was most pronounced in the non-epithelioid population, which is actually a smaller subset of pleural mesotheliomas. And so as we've seen in the lung when we look at immunotherapy versus chemo, it raises the question of whether combination immunotherapy plus chemotherapy would actually be better for all and, in particular, for all histologies in pleural mesothelioma. So this was looking at that concept. It took the standard chemotherapy, carboplatin-pemetrexed or cisplatin-pemetrexed, and then combined it with one immunotherapy, so slightly less than the combo immunotherapy seen in CheckMate 743, and that was pembrolizumab. And what they saw was that there was a small overall survival improvement in the group that got pembrolizumab. Again, that was most pronounced in patients in the non-epithelioid group, so those with sarcomatoid or biphasic histology. And this is really a prelude to several other trials that are coming out in mesothelioma, namely the DREAM3R trial, which is looking at chemotherapy plus or minus durvalumab. That control arm also includes IPI/NIVO, so that will be really important to be able to compare those, and then also the BEAT-meso trial, which is looking at chemotherapy-immunotherapy but also with an anti-VEGF agent, bevacizumab. So I think this was an important trial. It's a little bit of proof of concept, but there's still a lot that we're looking forward to. It's not quite practice-changing in the clinic, although I think it's certainly an option that people are using, but I'm looking for more data going forward. Dr. Aggarwal: It's incredible to see how far we've come in mesothelioma within the last decade. We are introducing immunotherapy. We're introducing novel agents in the first-line setting. Dr. Marmarelis: The other trial that I was interested in was KEYNOTE-789, which is looking also at patients with EGFR mutations and those that had the original osimertinib as their first-line treatment or another tyrosine kinase inhibitor and then had disease progression on that TKI. And this is an area of huge need. We have patients that do really well on targeted therapies, and then they have disease progression, and we're looking for additional targeted options, but we're also looking for effective chemotherapy options. And one of the questions that has risen from this is whether there's a role for immunotherapy. We know that immunotherapy alone in patients with EGFR mutations is not very effective when you look at a broad population, but in combination with chemotherapy, it's possible that it can add some benefit. So this trial looked at those that had EGFR mutations, had disease progression after a targeted therapy, and then it randomized them to chemotherapy plus or minus pembrolizumab, so chemotherapy plus or minus immunotherapy, and interestingly, it had no difference in the progression-free survival or the overall survival. So the 2 arms were really similar in terms of outcomes. There was also no difference in the overall response rates of the amount that the drug actually shrinks the tumor. So it really doesn't look like immunotherapy is adding much to chemotherapy for these patients. I think we still need to look a little bit closer because there are probably some patients with EGFR mutations that could benefit from immunotherapy, but we're really not very good at identifying those. One of the questions that comes up in this space is whether to add anti-VEGF treatment in addition to chemotherapy and immunotherapy. So there are some upcoming trials looking at that. Dr. Aggarwal: I think this was a trial that was actually very important and again, practice-affirming that this idea of continuing chemotherapy without adding immunotherapy, patients are not losing much. In fact, they're not gaining anything by adding immunotherapy as shown in this clinical trial. I think continuing immunotherapy, so continuing osimertinib, may be important in this setting also because we know that osimertinib can cross the blood-brain barrier. It can provide that CNS [central nervous system] protection. Dr. Marmarelis: Yeah, I think that's a great point that the comparison here is not chemotherapy plus osimertinib. It's chemotherapy alone. So I agree that the control arm is not quite what some of us do. I agree. I do the same as you do. I also just want to mention that the KEYNOTE trial and the previous trial about mesothelioma used pembrolizumab, which is made by Merck. We have received institutional funding, and I've served as an advisor as well as received honorarium from Merck.   Dr. Aggarwal: Melina, those were 2 very important studies and certainly, I think, answer some very relevant questions in clinic in the management of patients with EGFR-mutant lung cancer, for example. And then I think we look forward to more practice-changing data in mesothelioma. Kristin, I would love to hear research from ASCO from you. What caught your interest? Dr. Higgins: So I have a special interest in small cell lung cancer. And I think there was one important small cell lung cancer trial that I wanted to review with everyone. It was SWOG S1929. And SWOG is the Southwest Oncology Group, and it's a cooperative group that conducts clinical trials in cancer funded by the National Cancer Institute. And this is a randomized phase II trial of atezolizumab and chemotherapy followed by randomization to continuing the maintenance of atezolizumab with a PARP inhibitor. Now, we know from prior data that PARP inhibition is attractive for small cell lung cancer because PARP is expressed frequently in small cell lung cancer, and there is a biomarker called Schlafen-11 that preclinical data and prior data has shown can predict response to PARP inhibition. And this trial was sort of a proof-of-concept trial, a small, randomized phase II trial testing whether or not that Schlafen-11 biomarker could be used to direct therapy. Now, in this trial, there were 309 patients that were registered. They then had to have their tumor samples sent for central testing for the Schlafen-11 expression. One thing that I think is important to bring up is that in small cell lung cancer, there's this belief that it's really hard to get tissue samples from small cell lung cancer and it's a difficult thing logistically because it's just a lot harder to access these tumors. But interestingly, in this trial, 80% of patients had tumors that were evaluable for the biomarker, and the median time to the test result was only 7 days. So patients were able to get their tumor tested, get it sent out, get results in a rapid manner, and then be randomized based on these results. The primary endpoint for this trial was progression-free survival, and the primary endpoint was met. Progression-free survival was 4.2 months versus 2.8 months. Now, I think many people will say the magnitude of benefit here is not very much, but it's small cell lung cancer, and we don't have a lot of positive trials in this space, and we also don't have many trials that have used a biomarker to direct therapy. So I think for those reasons, it's really exciting to see these results. It was also conducted within a cooperative group with multiple different sites across the United States, and the fact of the matter is that we can do trials like this in small cell lung cancer patients, and I think it will sort of serve as a precedent for future trial design. Now, the overall survival for the trial is still premature. It didn't look that much different with the PARP inhibitor, but that doesn't mean that, again, things could change with more follow-up. And I really like the approach of this trial design, and I'm excited to see biomarker-driven trials in small cell lung cancer. Charu and Melina, what do you guys think about this study? And what do you think about our small cell lung cancer patients and our ability to conduct future trials like this? Dr. Aggarwal: I think this is certainly an advance. As you pointed out, Kristin, it shows us that we can conduct trials in the space. I think it offers a lens into the potential of personalized therapy in small cell lung cancer, which has eluded us for a very long time. The standard of small cell lung cancer has not changed significantly for a very long time, so I think this is very exciting and can't wait to see more things come in the future. Dr. Marmarelis: Yeah, I agree. I think we've always been asking for additional biomarkers, especially in such a difficult disease like small cell. And so this is really exciting to see potential biomarkers and that it was feasible to actually pose that question and study it. So that part's really exciting. Dr. Higgins: Great. And I should also say I was not involved in the study, and I'm not associated with any of the pharmaceutical companies that were involved in the study for S1929. And the final study that we wanted to talk about was the phase III LUNAR study, and this is sort of a different type of trial in the setting of advanced non-small cell lung cancer. It was studying tumor treatment fields with standard of care in metastatic non-small cell lung cancer after progression with platinum-based therapies. And first, I just want to step back and explain what tumor treating fields are. Tumor treating fields are applied to a patient with a transducer that's placed on the skin, and what it does is it applies an electrical field, and that disrupts mitosis when the cancer cells are trying to divide. And the mechanism of cell death is a little bit unclear. There are sort of many mechanisms that are postulated, one of which is immunogenic cell death, but we don't really know, I think, what's happening. But there have been studies that show improved results with tumor treating fields and other diseases. For example, particularly in glioblastoma multiforme, tumor treating fields are used in combination with surgery, radiation, and temozolomide (Temodar). So it's something that's being used in other disease sites, and this is some of the early data that we've seen in metastatic non-small cell lung cancer. And so in this trial, 276 patients were randomized to tumor treating fields plus standard of care or standard of care alone. Now, I should mention that this trial began enrolling patients in 2016, and so the standard of care was very different. After platinum-based therapies, the standard was considered docetaxel. Of course, platinum-based therapy alone for frontline treatment of advanced non-small cell lung cancer is also not the standard of care anymore. And so I think with that in the background, it does make interpretation of these results somewhat difficult, and that's probably the major caveat to this study. But nonetheless, patients were randomized, 276 patients. The primary endpoint of the study was overall survival. They were looking at progression-free survival and overall response rates as secondary endpoints as well as overall survival in patients that received immunotherapy versus just chemotherapy alone. And the trial was positive. Overall survival was improved. The median overall survival was 13.2 months for patients that received tumor treating fields with standard of care versus 9.9 months for standard of care alone. If you look at 3-year survival, it was 18% versus 7%. I think this is a new type of therapy for our patients with non-small cell lung cancer. It is somewhat of a difficult thing to wear the transducer, and you have to wear it for many, many hours. So that is one thing that I think can be difficult for patients that are using this treatment, but nonetheless, it is something new for advanced non-small cell lung cancer. I do know that the technology of tumor treating fields is being studied in other settings for non-small cell lung cancer, for stage III non-small cell lung cancer, for example, and also in the frontline setting. I think this trial kind of speaks to the fact that the landscape of advanced non-small cell lung cancer is changing so rapidly, and when we're studying something novel, we have to make sure that we make these trials feasible for enrollment so that we can get them completed rapidly, and we can get a readout and it doesn't become obsolete based on this shift in the standard of care. So I think it just really kind of drives home that we need to make sure that we're taking that into account with trial design. It's not standard of care changing right now, but it'll be interesting to see how the data evolves over time. Melina, I'm interested to hear your point of view because I know that these can be used in mesothelioma, maybe not that frequently. What is your experience with tumor treating fields, if any? Dr. Marmarelis: Tumor treating fields are approved as a device in pleural mesothelioma in the first-line setting in combination with chemotherapy. They have been used off-label in other settings, but that's the device approval. The trial that looked at tumor treating fields in mesothelioma was a single-arm trial, so there was no control arm, and it was really actually just looking at the safety of the device. So I have not used it personally in mesothelioma, although I know of patients and I know of real-world studies looking at its use, and I think it's potentially an interesting modality of treatment, especially in combination with immunotherapy, given that it really doesn't have a lot of additive toxicity. But I think the question is really, which patients are benefiting from it, and which patients are able to actually wear the vest in the case of mesothelioma? Dr. Higgins: Yeah. Any thoughts, Charu? Dr. Aggarwal: I agree, and I think this is going to be largely driven by patient experience. I think this is going to be quite onerous to wear this, carry the suitcase, so I would be very interested in patient reported outcomes as well as patient experiences and stories, which will really drive our use here. Dr. Higgins: Yeah, that's a great point. I should say that this trial was sponsored by Novocure. My institution does have other Novocure studies underway, and we receive research funding, but I was not involved in the study, and I did not personally receive any research funding. Dr. Aggarwal: Thank you, Kristin. This has been a wonderful review of practice-changing and some promising research that came out of the ASCO Annual Meeting.

On this episode of BackTable Urology, Dr. Aditya Bagrodia, Dr. Daniel Costa (UT Southwestern), and Dr. Xiaosong Meng (UT Southwestern) discuss patient selection and procedure for TULSA-PRO, a new transurethral ultrasound ablation system that incorporates real-time MR imaging, as a focal treatment option for prostate cancer. --- CHECK OUT OUR SPONSOR Profound Medical TULSA-PRO https://profoundmedical.com/ --- SHOW NOTES First, the doctors discuss the benefits of using MRI with transurethral ultrasound ablation (TULSA), which include direct visualization of anatomy, margins, and boundaries. They compare TULSA to other forms of focal management, such as cryoablation, brachytherapy, stereotactic body radiation therapy (SBRT). Compared to these methods, TULSA has lower risk of rectourethral fissures and preserves the posterior plane better, making salvage procedures more viable. Then, the doctors discuss ideal candidates for TULSA therapy, which include patients with intermediate risk and localized disease, patients with lesions in lateral or anterior portion of prostate, patients with medium sized prostates, low risk patients with lower urinary tract symptoms (LUTS) who do not want to undergo active surveillance. Patients with large calcifications may not be ideal candidates for TULSA, as the calcifications can be a shield for the ultrasound beam. The doctors recommend ordering a CT/MRI scan first to identify if calcifications are present to assess their sizes and locations. During imaging, it is also important to make sure the tumor is not close to key anatomical elements, such as the neurovascular bundle. When deciding between different focal therapies, it is important to balance oncological outcomes and quality of life preservation. Thus, the treatment decision should be a collaboration between patients, their families, the radiologist, and the urologist. The doctors also discuss special considerations for salvage therapy patients, brachytherapy patients, patient with urethral strictures, and patients with a prior history of TURP. Next, the doctors explain how to prepare patients for TULSA. The patient's colon has to be emptied in order to reduce MRI noise during the procedure. Additionally, the doctors help patients understand the immediate side effects of the procedure, which can include reduced semen volume, urgency incontinence from bladder and prostate irritation, and temporary erectile dysfunction, and semen retention. After the procedure, the urinary catheter will have to be left inside for five days to two weeks, depending on the volume of the prostate removed. There is a 20-25% chance of recurrence. Finally, they discuss specifics of the TULSA procedure. Dr. Costa and Dr. Meng perform these procedures at the university hospital, as they need access to MRI and anesthesia. They discuss the optimal MRI window for the procedure, patient positioning, as well as their two sweep method. The total procedure time is dependent on the volume of ablation and number of sweeps, but the average total time is 3 hours. Patients are discharged on the same day, and no narcotics are prescribed. Finally, they discuss the progress of a new prospective multi-center randomized trial comparing focal TULSA therapy to surgery for intermediate risk prostate cancer patients. --- RESOURCES TULSA Procedure https://tulsaprocedure.com/tulsa-procedure/about-tulsa-procedure/ Profound Medical https://profoundmedical.com/

Dr Kishan discusses the use of MRI-guided SBRT in prostate cancer to reduce acute genitourinary and gastrointestinal toxicity; findings from the MIRAGE study; and how MRI-guided SBRT allows for tighter planning margins, thereby reducing both physician-reported and patient-reported bowel and bladder toxicities.

Dr. Ehsan Balagamwala joins this episode of Butts and Guts during National Colorectal Cancer Awareness Month to discuss everything you need to know about how stereotactic body radiotherapy (SBRT) can be used to treat colorectal cancer. Listen to learn more about this type of treatment, how it differs from other radiation therapies, and who qualifies to receive it.

Andreas Rimner, MD, Memorial Sloan Kettering Cancer Center, joins us for a conversation about radiation oncology and currently available clinical trials. He discussed various ways patients can benefit from radiation therapy, including an overview of different types of radiation and different modes of treatment. Radiation therapy can be applied alone, or in combination with other treatments such as surgery, chemotherapy, or immunotherapy. Dr. Rimner is a radiation oncologist who specializes in caring for people with cancers of the chest, known as thoracic cancers. These include non-small cell and small cell lung cancers, pleural mesotheliomas, thymomas, lung metastases, sarcomas, and other rare tumors of the chest. He works closely with a highly skilled team of experts from many areas — including surgeons, medical oncologists, radiologists, medical physicists, and radiation therapists — to determine the best treatment options for his patients. HIs team uses the most advanced radiation techniques, including stereotactic body radiation therapy (SBRT) or stereotactic ablative body radiation (SABR), stereotactic radiosurgery (SRS), intensity-modulated radiation therapy (IMRT), image-guided radiation therapy (IGRT), intensity-modulated pleural radiation therapy (IMPRINT), MR-guided radiation therapy, and proton radiation to precisely target cancers while limiting damage to normal tissues.

Today, we are happy to introduce Dr. Bob Dess, a radiation oncologist from the University of Michigan, to our listeners!  Dr. Dess is joining us to discuss another type of radiation therapy called Stereotactic Body Radiation Therapy (SBRT). SBRT can be a faster and more efficient form of radiation therapy than conventional prostate cancer treatments.  Dr. Dess is an Assistant Professor in the Department of Radiation Oncology at the University of Michigan. He has published extensively in peer-reviewed journals on prostate cancer. He has collaborated to create novel prognostic models to characterize prostate cancer disease aggressiveness, to analyze racial outcomes, differences, and settings in which disparities are minimized, and to advance more convenient forms of treatment, including Stereotactic Body Radiation Therapy, and characterize the long-term quality of life post-treatment. Dr. Dess's guiding principle is to deliver the right treatment to the right patient at the right time. He is interested in maximizing efficiency, minimizing burden, and understanding the long-term toxicity risks of treatment.  Stay tuned to find out how SBRT compares with more conventional treatments for prostate cancer.
