Do you recommend adjuvant chemotherapy to a low risk T3N0 stage II colon cancer if there was bowel perforation upstream from the tumor, with mucosa underlying tumor itself being intact?
The upstream perforation is likely from another cause like inflammatory bowel disease, I am assuming. In this situation, I would offer chemo regardless of the upstream perforation. I would consider if they are eligible for a clinical trial that is incorporating ctDNA to help decide. But my understan...
How do you approach the treatment of HSCT-associated thrombotic microangiopathy?
TMA can be due to multiple insults: If the patient is on tacrolimus or cyclosporine, the dose should be reduced. These drugs cause the renal afferent arterioles to spasm, and RBC fragmentation can occur on that basis. It typically responds to a dose reduction If the patient was conditioning with TB...

How do you approach deciding which patients with hemophilia B to recommend for gene therapy?
There is no standard protocol for who gene therapy is recommended for, but certainly, potential candidates must meet all criteria according to the manufacturer's recommendations. Gray areas may exist if there is some preexisting liver disease, where hepatology consultation is desired to help determi...

What is your approach to managing iron overload in children with transfusion-dependent beta thalassemia who have adherence challenges or toxicity with standard chelation regimens?
I would divide the adherence issues into two populations. The younger children where a caregiver is responsible for administering the chelation, and adolescents where caregivers have passed on the responsibility to the patient. For the former, adherence is reinforced with an explanation of the possi...

Do you recommend definitive chemoradiation for unresectable gastric adenocarcinoma in a medically unfit patient?
Definitive is probably not the best term for what can be done. Only palliative doses are possible because the stomach is so sensitive, the GTV is difficult to clearly define, impossible to see on CBCT, the stomach changes shape from day to day, and moves with respiration. There would only be a less ...
How do the results of KEYNOTE-B15/EV-304 influence your preferred treatment for cisplatin eligible MIBC?
The management of urothelial cancer has undergone major changes in the last decade.We have seen a number of new drugs approved for relapsed BCG-refractory superficial bladder cancer. Additionally, we have seen a number of new approaches for the management of muscle-invasive bladder cancer (MIBC) or ...
What are the recommended prophylactic measures for managing or mitigating diarrhea when pertuzumab is combined with trastuzumab deruxtecan, given toxicity risk with each individually?
My understanding is that prophylactic anti-diarrheals were not required in the trial but left to institutional discretion. While the rate of diarrhea in DB-09 was 56%, most of these were Grade 1-2 (only 7% were Grade 3 or higher). As such, I am not starting antidiarrheals prophylactically, but I do ...
