Can a patient with MDS have ring sideroblasts in the absence of mutation such as SF3B1?
Yes, < 50% of MDS RS have SF3B1 mutation by NGS. Malcovati et al., PMID 32347921
What scenario would prophylactic Tocilizumab be considered to prevent Ipilimumab+Nivolumab (immunotherapy) induced toxicity in malignant melanoma?
Currently, there is no indication for prophylactic Tocilizumab with the data that is available. As a matter of fact, Tocilizumab is off-label for the treatment of immunotherapy-related toxicities (it’s indicated for the treatment of CAR-T-induced toxicities and cytokine release syndrome, though not ...
Would you be willing to give definitive chemo-radiation and chemotherapy to a MSI-stable T2N0 low lying rectal cancer in a young healthy patient who wants to avoid surgery?
More likely to recommend total neoadjuvant therapy hoping for induction of complete clinical response. In our hands, on average, we are able to conserve the rectum in about 55% of treated patients with excellent rectal function and a regrowth rate of less than 10%. Local excision will not address th...
Are you routinely using neoadjuvant cemiplimab for cutaneous squamous cell carcinoma of any site?
No
Would you offer a 2nd generation anti-AR or abiraterone after progression on ADT in patients with metastatic AR+, HER2 expressing salivary gland carcinoma?
Due to the rarity of the condition, there is limited data that strongly support any intervention in this situation. However, I see 2 potential targets in this case: HER 2 and AR. It would be helpful to know what these patients have been treated with before. If only AR was targeted, adding a HER2 age...
Would you consider a somatostatin analog for a patient with carcinoid involving ileum and appendix with positive mesenteric margin after right hemicolectomy and liver metastases that have been resected?
I generally would not unless there was a substantial amount of residual disease per se and/or there were symptoms of the carcinoid syndrome which is very unlikely after near total resection of metastases.Patients with small bowel NETs (carcinoid tumors) and liver metastases are rarely, if ever, cure...
How do you manage dry eye related to Pluvicto Lu-177?
This is a real but uncommon side effect of Pluvicto therapy. Per VISION, it will happen in maybe 3% of patients but almost never high grade. Interestingly, the absorbed dose for the lacrimal glands is 2.1 Gy/Gbq - which over 6 cycles full dose at 7.4 GBq/200 mCi per cycle means 92 Gy. There was a me...
How do you approach a patient with prostate cancer with sclerotic/lytic lesions found on a CT scan but not seen on a bone scan or PET-PSMA?
This can be a tough situation, as sometimes healthy individuals can have sclerotic or lytic foci in various bones for reasons unrelated to any type of malignancy. The first thing I would try to do is compare the CT scans to any prior imaging if possible. If these lesions are completely unchanged fro...
How would you approach grade 2 neurologic toxicity in a patient on daratumumab, dexamethasone, and lenalidomide for relapsed multiple myeloma?
Clarification of the question was made, and it was focused on peripheral neuropathy. The polyneuropathy in Dara/Rev/dex is mostly due to the Revlimid. Most neuropathy from rev, if any, is grade 1- 2. The first step will be to start with gabapentin without reducing the dose of Revlimid. It is a very ...
How would you treat ESRD patients on HD with locoregional squamous cell carcinoma of the anus?
Both FU and MMC may be used but one must modify the treatment around the dialysis since the FU infusion will be removed with dialysis. You could use 5 day bolus 5FU and give bolus after dialysis. It would be better to use capecitabine however and try to schedule between dialysis episodes (for exampl...
