What is the optimal frequency and duration of post-operative radiological surveillance following resection of a solitary fibrous tumor?
Partly depends on the subset of SFT. The classic variant is low-grade, indolent clinical behavior and can recur late (several years later) requiring (maybe less frequent) but long-term follow-up for 10 years or even beyond. The malignant SFTs have a shorter natural history and typical sarcoma follow...
Is there a role for DOAC use for patients with unprovoked PE, that have had recent sleeve gastrectomy with duodenal bypass?
Alterations in the gastrointestinal (GI) tract following bariatric surgery, as well as altered or reduced oral intake, have the potential to impair the absorption of both DOACs and VKAs in the acute setting. DOACs are absorbed in the upper GI tract, which is altered by the most common bariatric surg...

How do you treat metastatic RCC with fumarate hydratase mutation (Hereditary Leiomyomatosis and RCC [HLRCC])?
For patients with newly diagnosed brain metastases without a history of seizure activity, do you routinely start anti-seizure medication?
This is a common clinical question that has been repeatedly explored in meta-analyses and clinical guidelines. Consistently, there's no evidence to support primary prophylaxis for seizures in patients with brain tumors including brain metastases. In summary, the data does not support the routine use...
What is the role of surveillance imaging after first line therapy in patients with aggressive lymphomas?
Most relapses from complete remission in patients with diffuse large B-cell lymphoma are symptomatic. I am aware of no evidence that surveillance leads to the diagnosis of asymptomatic relapses that are more likely to respond to salvage therapy. My own concern about frequent surveillance is the adve...
What is your approach to optimizing pre-operative hemoglobin in patients with sickle cell disease?
Unfortunately, I am not aware of a more comprehensive document than the ASH guidelines. These are what I use to define my default management strategy, often in coordination with our dedicated hematology consult subspecialist service.
Would you consider a BRCA carrier patient for kidney transplantation?
I would certainly consider a potential recipient who is a BRCA carrier. Would involve genetic counseling as well as informed consent regarding the risk of malignancy post-transplant. The mortality risk, depending on co-morbidities, of remaining on dialysis is high and should certainly be considered ...
How would you evaluate a patient with an isolated high RBC count but with a normal hemoglobin and hematocrit?
My first question would be, how long has the elevated red cell count been present? I ask this because, in a study of 10,000 individuals, erythrocytosis was initially found in 88 but after a year only 11 still had this finding (Ruggeri et al., PMID 13679323). If therefore, the observation is recent, ...
Will you offer lurbinectedin with atezolizumab for patients with ES-SCLC during maintenance if they had brain metastases at baseline?
The IMforte trial specifically excluded these patients, a major drawback of this trial in my opinion. It may not be unreasonable to consider it, especially if the patient has a good performance status and is motivated to get it. However, I would discuss the pros and cons and make it clear that this ...
