Should we be utilizing prophylactic G-CSF in our patients with intermediate risk of febrile neutropenia due to the COVID-19 pandemic?
There are many functions of G-CSF, including repression of T-cell and NK cell function. Unless you are certain that growth factors are not modifying the immune network to the detriment of viral clearance—there is no data that growth factors help clear viral infections.
Given results of the IDEA study presented at ASCO, would you consider truncating adjuvant therapy with stage II colon cancer?
The question asked is how one would consider incorporating the recent findings from the IDEA study into the utilization of adjuvant chemotherapy for patients with stage II colon cancer. The findings from this landmark study indicated that under certain circumstances, specifically those of patients w...
What disease characteristics will guide your choice of alpelisib plus fulvestrant (per SOLAR-1) versus capivasertib plus fulvestrant (per CAPItello-291) in PIK3CA mutated advanced ER+/HER2- breast cancer after progression on 1L ET regimen, given both are now approved in this population?
In the absence of head-to-head comparison, I would use cross-trial comparison to compare the efficacy and safety of alpelisib vs capivasertib. mPFS are similar for both: HR 0.65 (11 vs 5.7 months) for alpelisib (SOLAR-1); and mPFS HR 0.6 (7.2 vs 3.6 months) for capivasertib (CAPItello-291). Therefor...
What are the current official guidelines regarding managing patients during COVID-19?

What is the drug of choice in order of preference for neuropathy associated with different agents used for breast cancer treatment?
Unfortunately, many of the large trials have not identified a strategy that is effective for CIPN. It is important to tell patients to avoid some supplements. Studies have shown that acetyl-l-carnitine can make the symptoms worse. There is some evidence that exercise may result in decreased symptoms...
How do you approach an otherwise healthy patient with an incidental 1 mm GIST involving the serosal surface in terms of staging workup, EGD, and surveillance?
We will need more information like location and mitoses per 50 HPF (or 5 mm). Please use the Sloan Kettering nomogram to determine the risk of relapse. Seems like a very low risk of relapse. NCCN recommends 6-month scans for the first 2 years and then once a year to finish 5 years. There is no need ...
How do you approach a patient with recurrent VTE who develops VTE again after reduction of apixaban to 2.5 mg bid?
Several factors play into this decision for me. Is the patient obese? Obese patients tend to give me pause for dose-reduction of DOACs. As such, half-dose apixaban may have been relatively underdosed for an obese patient and I would not call it DOAC failure, rather I would increase the dose to usua...
Do you recommend MSI testing to any tumor that is not already eligible for immunotherapy?
The accelerated approval of pembrolizumab in MSI-H tumors was based on data from 149 pateints with MSI-H or dMMR cancers from five different single arm studies. Ninety of those patients were colorectal, the remaining 59 were a mix of 14 different types. The ORR for the entire group was almost 40% wi...
How do you approach adjuvant therapy for resected Stage I Ewing sarcoma of the kidney?
From a chemotherapy standpoint, all stages of Ewing Sarcomas are approached the same way. There are differences in surgical approach between localized disease versus metastatic disease. We give VAC alternating with IE for six cycles, each. Since this is resected, this regimen should be given in the ...
How well does a negative non-contrast MRI of the brain exclude metastasis in a patient with squamous cell carcinoma of the lung?
I don't think the question has enough information to give a good answer. For example, if it was a T3, N2 NSCLC, or a small cell, then "yes" I'd repeat the MRI with contrast. On the other hand, if it was a T1, N0 NSCLC, then "no", I wouldn't. In other words, if I thought there was a real risk of havi...
