How do you approach treatment for a patient with a biochemical relapse while on maintenance lenalidomide after autologous stem cell transplant for multiple myeloma?
Biochemical relapse (i.e. increase in M-spike or light chains meeting criteria for progression on two occasions without clinical progression) is an indication for starting treatment in my opinion. I have seen some recommend increasing the dose of lenalidomide to 25 mg in the hopes this will bring di...
Would you ever switch capmatinib to tepotinib or vice versa for patients with NSCLC with MET ex 14 skipping mutation who are responding to treatment but with ongoing edema despite dose reductions?
The MET TKIs universally cause edema that progressively develops and persists with these drugs. Unfortunately, switching from capmatinib to tepotinib or vice versa will not improve the peripheral edema. Symptomatic treatment and dose interruption or reduction are the best management strategies.
Would you offer neoadjuvant chemotherapy to cT1c N0 triple negative breast cancer with metaplastic features in a young patient?
I would argue to proceed with neoadjuvant chemotherapy in this patient - as one could monitor anti-tumor response and offer capecitabine if residual disease. As not a T2 tumor, this patient does not fit the criteria for the KEYNOTE-522 regimen. One may also consider hereditary genetic testing for th...
How long do you continue temozolomide in a patient receiving capecitabine/temozolomide for well-differentiated neuroendocrine tumor?
The true answer is that we do not know. There is no question the CAPTEM combo is effective and the highest quality data comes from ECOG E2211 which was just updated at this year's ASCO. In that trial, patients received up to 13 cycles. In the past, there was the temptation to continue CAPTEM as long...
If a patient had a grade 2 infusion reaction to initial dose of IV Rituximab, can you give subcutaneous Rituximab for cycle 2 or continue with IV Rituximab?
I would likely continue IV rituximab until no more infusion reactions are observed before switching to SQ.
If using durvalumab/tremelimumab for advanced HCC, must the tremelimumab be given with the first cycle of durvalumab?
Understandably, one may be nervous about the use of tremelimumab because of prior experience with other CTLA4 checkpoint inhibitors like ipilimumab. With tremelimumab being given only once, such concerns would be less or dissipate all together. Sure, durvalumab plus tremelimumab should be given toge...
Given several PARP inhibitors approved or with emerging positive data in castrate resistant prostate cancer, how do you decide which one and when to use?
At this point, it's easy. In the prechemo mCRPC state, the answer is olaparib, but it is expected that rucaparib will be an alternative. In the mCRPC state post chemo, could be either olaparib or rucaparib. The others are not yet approved. We are participating in the trial AMPLITUDE, which is lookin...
Do you continue endocrine therapy for women with HER2+/HR+ metastatic breast cancer when starting a HER2-directed antibody-drug-conjugate?
In general, no, I would not. I do think there is room for case-by-case evaluation in determining the right course of action for a particular patient, e.g., based on how strongly the patient's tumor seems driven by ER vs HER2, how they have historically responded to ER-directed vs HER2-directed thera...
Are there any unique toxicity concerns with combination of ramucirumab/pembrolizumab as compared with other available treatments for metastatic NSCLC?
Unique toxicities issues were not seen with ramucirumab and pembrolizumab. The adverse events aligned with known side effects of the individual agents as previously reported. Toxicities were less than those seen in the standard of care arm. Many patients are interested to learn about a potential reg...
How would positive ctDNA results after 12 cycles of adjuvant FOLFOX affect your management for patients with colon cancer?
I think the question should be, should you be testing ctDNA post adjuvant therapy? I do not want to order a test and then not know what to do with a positive result. I can imagine that this would cause fear and panic in certain patients.
