Do you favor 24 hour urinary metabolites over random urine collection when screening for MCAS?
In my practice, I currently use 24-hour urine metabolites. The 24-hour urine collection has been extensively validated and its use is supported by the literature (see review: Butterfield et al, PMID 35346887).That being said, a spot urine collection is now available and this is far more convenient f...
How would you work up a mildly neutropenic patient (ANC >800) with family history of neutropenia and personal history of occasional mouth sore?
The first question is whether to evaluate the neutropenia at all. With ANCs >800 and only occasional mouth sores, is a diagnosis necessary, and should the term “neutropenia” be used at all? If the family’s origin is in a part of the world where the Duffy null phenotype is common (e.g. Africa, parts ...

Do you use liver SBRT to areas previously treated with Y90 and subsequently failed?
Prior Y90 is a risk factor for liver decompensation that's hard to quantify. If there is relatively low volume disease and I am retreating with complete overlap of the prior TARE, I don't think there isn't any increased risk with retreatment. If the TARE went to more than 1-2 segments, I would be co...
How do you choose between neoadjuvant and adjuvant chemo-immunotherapy for patients with resectable stage II-IIIA NSCLC?
The billion dollar question. For patients with resectable stage II-IIIA NSCLC, how do you choose between neoadjuvant and adjuvant chemo-immunotherapy in light of the recent FDA approval of the CheckMate-816 regimen? Of course, this approval quickly followed in the footsteps of the FDA approval of at...
What is a reasonable hemoglobin goal for patients with chronic anemia presenting with acute MI?
The diversity of acute myocardial infarction (AMI) does not allow a monolithic answer to this question. The recent MINT study—an important contribution presented at AHA 2023 and published in NEJM—highlights this complexity. Although MINT, which randomized anemic patients with AMI to liberal versus r...
Do you diagnose MCAS if a patient is concurrently on drugs known to cause non-specific mast cell degranulation?
Yes, MCAS may be diagnosed if a patient is on drugs known to cause non-specific mast cell activation.The reason for this answer requires a better understanding of MCAS criteria and etiology. In 2022, an expert consortium proposed revisions to the classification of mast cell activation disorders. (Va...
How do you manage patients desiring home hospice but with severe thrombocytopenia and/or anemia due to advanced malignancy?
As a pediatric hematologist/oncologist and pediatric palliative care physician, I can only speak to our approach with children, which may be quite different than the adult world. In our community, we are not able to provide blood or platelet transfusions in the home. For children who are profoundly ...

What are your top takeaways from ASCO GU 2025?
In terms of practice-informing presentations in prostate cancer here are my top 3: GROUQ-PCS 9 trial (Canada, abstract 22). This trial led by Niazi et al tested whether metastasis-directed radiotherapy based on conventional imaging to up to 5 sites provided benefits in delaying rPFS or PSA progressi...
