How do you manage patients with chemotherapy-induced paronychia?
I manage patients with chemotherapy-induced paronychia with a few tricks: First, ensure that there is no infection (active drainage, especially purulent) is more indicative of infection, as well as appropriate hygiene. Topical steroids and soothing soaks (such as Domeboro or diluted distilled white ...
Do you routinely offer antiviral prophylaxis for patients receiving chemoimmunotherapy?
Yes, with R-CHOP and similar therapies for anyone who may have had chickenpox. I have seen shingles during treatment. I have not been doing routinely for younger patients who had VZV vaccines. Yes also for anyone with a history of HSV. Usually acyclovir BID.
In light of ALK-directed therapy, what is the role of chemotherapy for patients with newly diagnosed ALK+ DLBCL?
I haven’t seen any data on ALK inhibitors in DLBCL, I’m assuming partly since it’s a small subset of DLBCL. Presumably, toxicity would be similar to, say, a BTKi + R-CHOP? Maybe would consider off label in the R/R setting, but would not use upfront.Those with ALK+ ALCL typically do well. In that sce...
Would you continue adjuvant FOLFOX for a patient with stage III colon cancer and triple-vessel coronary artery disease who developed NSTEMI after the first cycle?
This is a challenging scenario where the patient has existing triple vessel CAD and developed NSTEMI after 1st cycle. We all agree that 5-FU based therapy is the backbone for adjuvant therapy of stage III colon cancers. There are no clear cut guidelines in this case and management is per expert reco...
Are there situations in which neoadjuvant chemoimmunotherapy + surgery would be preferred over chemoradiation + consolidative immunotherapy for stage III lung cancer?
We are good at controlling tumors of one billion cells (1 cm size), less so for one trillion (10 cm). From a radiobiology point of view, when I see a resectable T4 tumor due to size over 7 cm, I usually ask my surgeons if they can please take it out. You suddenly get rid of half a trillion tumor cel...
How would you approach therapy for a patient with smoldering multiple myeloma whose light chain ratio has increased to greater than 100 over several years in the absence of any other myeloma-defining events?
I struggle with this as well, but the serum free light chain ratio (SFLC-R) at 100 is not magical for a patient that you've been following. An SFLC-R>100 is predictive of an increased risk to develop CRAB criteria of 60-90% w/in 2 years. This prediction is refined by measuring 24hr UPEP using a bar ...
Should IMPower010 results be extrapolated to superior sulcus tumors treated with chemoradiation and surgery?
No. Patients with superior sulcus NSCLC, for whom the standard of care is preoperative chemotherapy and radiation therapy followed by surgical resection, would all have been ineligible for IMpower010, which used chemotherapy +/- Atezolizumab in the purely adjuvant therapy setting. Therefore, the res...
What are your recommendations for management of patients with familial polycythemia due to EPOR mutation during pregnancy?
This is not a question that has a definitive answer since I know of no reports dealing directly with this uncommon situation and I have never treated such a patient. I have, however, successfully treated many pregnant vera patients, who have a constitutively-active erythropoietin receptor (EPOR) due...
How do you treat metastatic, wild-type GIST?
Majority of these are SDH deficient. For these patients, if a clinical trial is available, that would be preferable. From a SOC standpoint, EU investigators have data on Regorafenib. For the rare WT GIST with B-raf mutation or NTRK fusion, appropriate targeted therapy would be indicated.
What is your approach to CNS surveillance in resected superior sulcus tumors given high rates of intracranial metastasis in this population?
Despite the quantum improvement in complete surgical resection, pathologic complete remission, and overall survival rates in S9416/INT-0160 (the trial that established trimodality chemoradiation followed by surgery as the standard of care for superior sulcus NSCLC almost 2 decades ago), distant recu...
