How would you counsel a woman with a strong family history of thrombosis about oral contraceptives?
This can be a complex question for which there are likely no specific data or guidelines upon which to base a recommendation. ASH has published guidelines on thrombophilia testing in VTE (Middeldorp et al., PMID 37195076). They specifically recommend against testing prior to COC prescription. The ra...
Is your standard of care for newly diagnosed advanced classical Hodgkin now nivolumab-AVD based on SWOG 1826?
I think the new standard of care for newly diagnosed patients with advanced classical Hodgkins Lymphoma is now nivolumab-AVD based on the early data from SWOG 1826. While we often wait for more mature data, the early improvement in PFS and the more favorable toxicity profile of this regimen over BvA...
What is your approach to chronic non-immune mediated thrombocytopenia management in children?
There are whole textbook chapters on this topic, and we use a variant of this question to review the differential diagnosis of thrombocytopenia with our fellows as a didactic exercise. So I take from this question, which is an important one, what might be a framework to consider the differential dx ...
What is your preferred first-line therapy for transfusion-dependent beta-thalassemia?
Transfusions are the backbone of therapy for these individuals. Reducing transfusion burden is advantageous to minimize iron loading, space out transfusions, and improve quality of life. At present, there are 2 agents available - luspatercept and mitapivat. The clinical trial endpoints for both are ...
When consolidating DLBCL with radiotherapy, do you treat all originally involved sites, or just initially bulky and partial responder sites?
When consolidating DLBCL with radiotherapy, several parameters must be taken into consideration. a) Is radiation therapy part of the treatment plan "on top" of full systemic treatment because of a certain risk situation due to not-optimal response of disease to systemic treatment (for example, FDG-a...
Is enteric-coated aspirin acceptable to use in polycythemia vera or ET?
Admittedly, this is a question I had not considered before viewing this query, as I rarely, if ever, prescribe enteric-coated aspirin. In the absence of a bleeding diathesis such as von Willebrand disease, platelet count greater than one million/mm³, or active GI bleeding, low-dose aspirin (75/81/10...
Would you consider perioperative antifibrinolytics for mild factor 7 deficiency undergoing surgery?
I do use antifibrinolytics in factor VII deficiency; however, it depends on the specifics of the surgery (i.e., mucosal surface surgery, sequelae of bleeding should it occur - spine vs oral), the patient's bleeding history, and the factor VII level. Here, I wonder if the original diagnosis was corre...
Can aplastic anemia present with multiple infiltrative bone lesions, such as in the spine and pelvis?
There are several studies showing diffuse hypointense pictures with an infiltrative-like pattern on MRI in aplastic anemia and MDS. Some aplastic anemia and refractory cytopenia of childhood show patchy pattern of hematopoiesis with some regions having increased fat fraction and some remnants of hem...
Would you use routine PET scans after two cycles of R-CHOP to guide first-line treatment de-escalation in low-risk (aaIPI = 0) DLBCL patients?
This phase III trial suggests that in very low-risk limited-stage DLBCL (aaIPI = 0), patients who achieve a negative PET after two cycles of R-CHOP can safely receive only four total cycles instead of six, with similar 3-year PFS (92% vs 89%) and less toxicity. However, the results apply to a highly...
How do you approach relapsed idiopathic HLH?
This question is quite non-specific - the answer depends very much on the specific context (child, adult, relapsed after what treatment?) and as such, can only be answered in broad strokes.First, ensure that it is truly idiopathic – check EBV, CMV viral loads, and other viral/infectious triggers as ...
