How would you confirm the diagnosis of splenic marginal zone lymphoma without utilizing splenic biopsy or splenectomy?
You can usually make the diagnosis by immunophenotyping of peripheral blood and bone marrow. The typical morphology of circulating cells is "villous cells"; cells with long cytoplasmic projections around the entire perimeter of the cell. The typical phenotype is CD20+ (bright), CD5-, CD10-, CD23- as...
In patients with multiple basal cell carcinoma lesions on vismodegib, would you hold vismodegib while delivering radiation therapy to one locally advanced BCC lesion that was not amenable to surgery?
I agree. Based on the recently published paper in JCO (Barker et al., PMID 38630954), vismodegib can be safely administered with radiation therapy for locally advanced BCC. RT + vismodegib yielded high rates of control and progression free survival.
What is your approach to counseling patients who require definitive radiation therapy to the head and neck but for whatever reason, cannot/will not undergo recommended extractions?
I am fortunate to work at a center where we have dentists and oral surgeons on-site. They carefully evaluate all our patients scheduled to undergo H&N RT, make recommendations, and perform the extractions. In the unusual scenario where the patient refuses recommended extractions, I proceed with trea...
What treatment would you recommend for a patient with non-mutated Stage III lung squamous cell carcinoma with relapse following neoadjuvant chemoimmunotherapy, surgery, and during adjuvant immunotherapy?
If relapse is later than 6 mo since chemo discontinued, retreat with the same chemo. If relapse is less than 6 mo, can consider alternative therapy such as doce +/- ram, a clinical trial, or pembro/ramicirumab as in SWOG trial.
In a patient with a Factor V Leiden heterozygous mutation but no prior thrombosis, would you consider using a JAK inhibitor for the treatment of spondyloarthritis or rheumatoid arthritis if other options have been ineffective?
1. I'd love to hear others' thoughts who are more versed in thrombotic diastheses and JAKi's.2. The only article I could find assessing this showed no differences between the JAKi arm and the tumor necrosis factor inhibitor arm regarding patients with thrombophilia mutations (Weitz, et al., PMID 363...
How would you manage an elderly patient with mild pancytopenia who refuses bone marrow biopsy and whose flow cytometry is suggestive of CMML/MDS?
It depends on the actual age of the patient - 70s, 80s versus 90s. If 80s or 90s and not transfusion dependent - suggest observation as likely low-risk disease. Alternatively, if there is a need to start hypomethylating agents then would send peripheral blood for NGS and cytogenetics especially if h...

How do you approach the management of basal cell carcinoma with single lymph node involvement?
If all the tumor has been resected, I would recommend adjuvant XRT on the nodal basin, depending on the age of the patient. For very old patients or patients with comorbidities, observation might be warranted. If there is remaining BCC visible on examination or scans, I would treat systemically with...
What is your preferred graft source and conditioning regimen in a patient with Fanconi anemia and AML undergoing stem cell transplant?
I'm assuming that the patient has now secondary AML evolving from FA. If this is the case, I would suggest a reduced-toxicity MAC with Flu-based regimen and avoiding TBI (for obvious reasons). An IV BU PK-directed regimen such as Bu4Flu seems to be a reasonable regimen. As for the source, BM is pref...
