Do you approach the treatment of post-lumpectomy DCIS which is only present within an intraductal papilloma differently, if it does not involve adjacent breast tissue?
From the medical oncology perspective, I would consider chemoprevention with endocrine therapy for this patient. Prior series have shown elevated relative risk in patients with papillomas with atypical cells (although not as high as DCIS itself). I am not sure about the size of the DCIS within the p...
Do you wait to treat small asymptomatic brain metastases until they reach a certain size?
I typically treat all lesions on MRI that are found to be concerning for brain metastases. This is after a discussion with our neuroradiologist colleagues. If there is uncertainty that a small lesion may not be a brain metastasis, then I will elect to follow with a surveillance MRI and treat in the ...
For gross hematuria from a primary bladder tumor, what palliative radiation regimen would you recommend?
I found that 36 Gy/6 Fx delivered weekly is a great option for palliation.This has been used in curative system, as well, but I find it to be particularly helpful in elderly patients or those with travel issues. There is a phase 2 study in patients who are medically inoperable and the local control ...
Have you changed your practice in treating CRAO with IV thrombolysis?
The recent THEIA trial had a limited sample size to draw conclusions, even though there was a non-significant trend of improved visual acuity initially in the thrombolysis group. Even the TenCRAOS trial had a small sample size with recruitment challenges, where subtle small differences cannot be acc...
When will you prescribe 3 v. 6 months of FOLFOX or XELOX for the adjuvant treatment of colon cancer?
This set of studies will do more to reduce toxicity for patients than any other studies presented at ASCO this year. Based on these results, I plan on treating stage III patients as follows: 1. For T4 and/or N2 patients, I will continue to recommend FOLFOX or CAPOX for 6 months, and continue to adju...
Does a very high Oncotype score influence your approach to adjuvant treatment in a patient with ER positive breast cancer?
This is a very intriguing question that has a simple answer. There is no data on choice or aggressiveness of chemotherapy and resulting benefit in patients with higher oncotype recurrence score. What regimen to use remains a judgement call, but for most patients with ER+/node negative tumors with a ...
In light of the recent results from STAMPEDE and LATITUDE, to which patients with newly diagnosed metastatic prostate cancer are you offering up-front abiraterone vs. up-front docetaxel?
The high volume patients who were getting chemo will be offered abiraterone provided the cost of the drug will be covered. I will hold off on the low volume patients for now- the median rPFS for the low volume patients on ADT alone on the GETUG 15 was 21 months. I would also not treat M0 patients . ...
Would you use bone marrow MRD status to guide stopping daratumumab early at 1 year instead of the recommended 3 years of therapy per the AQUILA trial for high-risk smoldering myeloma?
I would venture to say that there is probably a 0% chance that MRD negativity would be achieved with daratumumab alone. The CR rate was 8.8%, but MRD was not assessed, and I would doubt that MRD negativity was achieved in any patient. That said, we can't really extrapolate whether 1 year and stoppin...

In patients with advanced endometrial cancer who you plan to treat with chemotherapy + immunotherapy (per GY018 or RUBY), how and when do you utilize adjuvant EBRT and/or brachytherapy?
Reading the question at face value - does advanced endometrial cancer mean stage IVB? III/IVA? If IVB, there is not routinely a role of 'adjuvant' EBRT or BT.Given the discussion of adjuvant therapy, I presume the question is asking for the small fraction of RUBY and GY-018 patients who were stage I...
