Would you ever consider stopping immunotherapy in a patient with metastatic melanoma after achieving a good response?
Yes, I would consider stopping immunotherapy in a patient with metastatic melanoma after achieving a good response.Data of 655 melanoma patients treated in pembrolizumab phase 1 KEYNOTE-001 study has shown 95 patients (14.5%) achieved CR after a median follow-up of 32 months. Treatment was discontin...
What are your top takeaways in GU Cancers from ESMO 2025?
KEYNOTE-905: These impressive results change the management paradigm of patients with MIBC who are surgical candidates but are not cisplatin-eligible. Over time, it may be that EVP perioperative therapy becomes the standard of care for all patients with MIBC with plans to proceed with cystectomy. I...
Are there any trials currently studying low-dose RT for confirmed COVID-19 infections with associated pneumonia?
This is a joint reply from a team developing a prospective trial to answer this question:Minesh Mehta, Arnab Chakravarti, Walter Curran Jr, James Fontanesi, Vinai Gondi, Michael Kasper, Deepak Khuntia, Rupesh Kotecha, Ramesh Rengan, Leland Rogers, Charles B. Simone II, James Welsh, George WilsonThis...
Are there any contraindications to Pluvicto therapy you personally use, given that there are none directly provided by the manufacturer?
In this situation, it is helpful to review the eligibility and exclusion criteria from the VISION protocol directly. These can be found at NCT03511664 (Sartor et al., PMID 34161051). Many of these patients have been heavily pretreated, including prior taxane therapy, so my main concern is that they ...
Given the final publication of NSABP B-51, for which patients meeting trial eligibility would you still recommend regional nodal irradiation?
The very first thing that should occur before one makes a decision about what they are going to do is to understand how the trial was designed and who was actually accrued to it. The first point is that B51 was a superiority and not a non-inferiority trial. A very related point to that is that they ...
What is your treatment paradigm for rectal cancer in the setting of COVID-19?
We haven't changed our standard recommendation: short course radiation -> 3-4 months of FOLFOX. In a very timely manner, the RAPIDO ASCO abstract was released here in May. It showed that the patients who received short course radiation -> FOLFOX had improved pCR, less disease related treatment failu...
How would you boost a high-risk prostate cancer patient who received standard fractionation treatment and is not able to get LDR boost given COVID-19?
I will assume for the sake of argument that he is also getting ADT as part of his treatment. If he has responded well to ADT (I like to see about a 90% drop in the PSA within 3 months), my preference would be to try to delay until it's reasonable from an infectious disease perspective to proceed wit...
How do you apply the concept of a lumpectomy bed boost in the setting of oncoplastic surgery?
This is a very common and often frustrating issue in patients I absolutely feel the need to boost (younger, larger tumors, high grade). I now consistently request my surgeons place a 3D tissue marker (brand name Biozorb) which preserves the location of the lumpectomy despite oncoplastic reconstruct...
When would you recommend abiraterone concurrently with RT for high-risk prostate cancer?
The trial got published in NEJM. It confirms survival advantage and skeletal mets advantage with abiraterone for metastatic disease similar to the Latitude study. This will certainly be an option for metastatic disease at presentation (along with docetaxel until comparative studies comparing docetax...
Would you give PMRT to a young woman with a T1-2 breast cancer with a micromet on SLNB?
No great data as far as I know. In general, I treat micromets as ~pN0. @Dr. First Last and colleagues reported on LRR rates and prognostic factors for failure in pN0 patients treated with mastectomy to identify subsets of node-negative patients with sufficiently high risk of LRR who might benefit fr...
