What is your preferred first-line treatment for metastatic melanoma in a patient with a class 2/non-V600 BRAF mutation?
Class II BRAF mutations have intermediate kinase activity and are much less likely than V600E or V600K mutations to respond to traditional BRAF+MEK inhibitor therapy. Targeted therapy should not be used as a front-line therapy in these patients. Immunotherapy (and immunotherapy-based front-line clin...
What is your preferred chemotherapy backbone (FOLFOX or FOLFIRI) when combining with encorafenib + cetuximab in the 1L setting for BRAF V600E-mutant mCRC?
In my practice, the treatment backbone regimen decision is driven by patient factors - thoughts about hair loss, current bowel function, performance status, existing neuropathy, and other comorbid conditions. All things equal, I prefer FOLFOX. Recent updates from ASCO GI show good activity for FOLFI...
What are your top takeaways from ASCO GI 2026?
GLP1 agonist use is associated with improved outcomes for colorectal cancer in a retrospective United States study. Now we need to incorporate this into randomized trials. I think this also provides more evidence that metabolic syndrome type issues may help explain early-onset colorectal cancers. W...
Prior to gender affirming surgery, do you hold estrogen (or convert to transdermal) to minimize postoperative VTE risk?
I'd divide this into 2 sub-questions: what to do in a patient who has a history of thrombosis, and what to do in a patient without a history of thrombosis. In a patient with prior thrombosis, I would generally have them on indefinite anticoagulation alongside ongoing estrogen use. We know that trans...
How would you approach anticoagulation for a patient with acute bilateral pulmonary emboli related to malignancy, but with a concomitant cavitary lung mass experiencing episodic, small-volume hemoptysis?
This is an interesting question to which we need to apply the art of medicine, weighing the risks and benefits of treatment. The major fatal events in this exact scenario are: Recurrent PE from undertreatment. Sudden massive hemoptysis after aggressive anticoagulation. The physician's management s...

Given the emerging benefit of neoadjuvant immune checkpoint inhibitors in selected patients with cutaneous melanoma, when should lymph node basin ultrasound or cross-sectional imaging (CT/PET) be considered prior to wide local excision (WLE) with or without sentinel lymph node biopsy (SLNB) in patients with clinically node-negative disease?
We usually would argue for cross-sectional imaging for T4 tumors and above. In the end, it will be clinical gestalt. If the pathologist confirms "no dermal attachment", then it is an argument for doing cross-sectional imaging. There is no guidance or evidence to support the idea that imaging for thi...
What is the current paradigm for breast cancer diagnosed with isolated metastases prior to initial treatment?
Surgery of the primary did not significantly improve overall survival in which patients were randomly allocated to receive systemic therapy alone or (for responding patients) to systemic therapy followed by primary tumor resection in the trial conducted by ECOG-ACRIN (Khan et al., PMID 34995128), at...
Are there reasons to not use prostate SBRT when treating the prostate +\- proximal SV?
Early trials such as HYPO-RT-PC which aimed to validate a 7-fraction SBRT dose schedule by comparing it to the standard of care at the time, conventionally fractionated EBRT, utilized a treatment volume consisting of the prostate alone without the seminal vesicles (SVs). While there was some suggest...
What is the optimal duration of ADT for unfavorable intermediate risk or high risk localized prostate cancer treated with SBRT instead of conventionally fractionated or hypofractionated RT?
There is no available data from randomized trials to support any modification in the choice of ADT (GnRH agonist vs antagonist) or use of abiraterone acetate, or on the duration of ADT (4-6 mo vs 2-3 years) based on the form of radiation, and thus I follow the NCCN guidelines that provide recommenda...
