For LS-SCLC with radiographic CR after chemotherapy, is there a time point beyond which you do not offer radiation if there is a delay in initiation of radiation?
I don't think we really have any data guiding this scenario. We know that optimal benefit is achieved when definitive RT is given within the first 2 cycles of chemo. However, I don't think that chemo alone is adequate for total eradication of disease. If the patient is within 1-2 mos of completing c...
How do you approach treatment of 1p19q non-codeleted high grade gliomas?
The question focuses on the management of 1p19q non-codeleted high-grade gliomas, which for all practical purposes translates roughly to the entity that by legacy terminology has been referred to as anaplastic astrocytoma. This question has come into focus with the recent publication of results of t...
Would you offer adjuvant chemotherapy to a post menopausal woman with T1-T3 primary tumor with 4 positive axillary LNs and OncotypeDX score less than 15?
The recurrence score and other genomic assays have been clinically useful in predicting chemotherapy benefit in HR+, HER2-, lymph-node–negative breast cancer and more recently in women with 1-3 positive lymph-nodes (Kalinsky et al., PMID 34914339). At this time, there is no role for genomic assays w...
In a patient with high risk acute promyelocytic leukemia, when do you consider ATRA+ATO with GO vs ATRA+ATO with idarubicin?
Given the recent publications with ATRA/ATO and GO in high risk patients or low risk patients who develop leukocytosis (Blood 2017) and the long term follow up of the comparative study form the NCRI AML Working Group (Blood 2018), GO is my preference in all cases unless there is hepatic toxicity or ...

In NSCLC, would you manage other MET alterations, such as a MET T618T mutation, in the same way as a MET exon 14 skipping mutation?
It depends on the specific MET alteration. For example, nonsynonymous SNV mutations in the juxtamembrane region that affect the Cbl binding site, such as Y1003F, may exhibit oncogenic potential similar to exon 14 skipping mutations. However, synonymous mutations such as the one in question, T618T, m...
How would you treat a patient with two concurrent plasmacytomas whose bone marrow showed no evidence of multiple myeloma and has no other MM defining features?
This is by definition Multiple Myeloma and I would treat it as such with systemic induction chemotherapy followed by transplant. These patients do better than the standard MM oftentimes. IMWG Criteria for the Diagnosis of MM | Inl Myeloma Fn

How does the presence of indeterminate lymphadenopathy on PSMA PET scan alter your management of unfavorable intermediate-risk prostate cancer?
Summary: In practice, I usually review the imaging myself and attempt to evaluate for common pitfalls of interpretation or evidence that may convince me of a true positive. Often, I find a second review by a blinded radiologist helpful. Unless I am highly suspicious of a false positive, I often err ...
What is your escalation strategy for chronic GvHD?
There are now several available options for steroid resistant cGVHD. The old standbys - ECP and rituxan are useful in about 30% of patients. Ibrutinib was the first new drug to get FDA approval. Unfortunately, I don't think the real-world experience is anywhere near as good as the trial (Chin et al....
