How do you differentiate primary from secondary iron overload?
Medical history helps- transfusion history, chronic hemolytic anemias, ESRD on HD, and inflammatory conditions increase the risk of secondary iron. In my practice, I use MRI to help distinguish between primary and secondary iron overload. In primary iron overload, the iron will only be seen in the l...
Do you consider bleeding risk in elderly, frail patients with atrial fibrillation to be similar for all NOACs?
I believe that apixaban carries a lower risk of bleeding, with particular reference to GI bleed, when compared to rivaroxaban and dabigatran. This is true in the population of AF patients at large and most probably in frail patients as well.
Would it be reasonable to offer a patient with CLL a treatment break from acalabrutinib or any BTK inihibitor after a period of time, assuming good response?
It is certainly reasonable to take breaks and I have done this for certain patients in my practice. For example, in older or frail patients whose disease is already under great control, I think it is reasonable to have a “drug holiday”. With continuous long-term use, it is almost inevitable to run i...
When would you consider testicular RT prior to TBI for BMT?
In children with ALL treated with systemic chemotherapy alone (no transplant), the risk of testicular recurrence is ~15-20% (Br J Haematol 2003;123:396, Br J Haematol 1998;102:656). In adults with AML treated with standard chemotherapy, with or without transplant using a chemotherapy alone condition...
Will you recommend pirtobrutinib following a prior covalent BTKi in patients with cardiac comorbidities?
In the MCL patients treated on the BRUIN trial, treatment was well tolerated in general with a low rate of treatment discontinuation or dose reduction. As far as cardiac toxicities, no grade ≥3 treatment emergent AEs of hypertension were observed. Atrial fibrillation/flutter (AF) was reported in 6 (...
In a patient with cardiac light chain amyloid who has significant heart failure symptoms, including inotrope dependence at presentation, how much clinical benefit does treatment provide?
In patients with cardiac light chain (AL) amyloidosis who present with significant heart failure symptoms and inotrope dependence, the clinical benefit of treatment is a complex and nuanced issue. This scenario often reflects an extreme end of the disease spectrum. Historically, patients with advanc...
For patients with a history of pregnancy loss, do you evaluate for PAI-1 polymorphisms as part of a thrombophilia workup?
I do not.The relationship between PAI-1 polymorphisms and thrombosis is complicated, and general guidance suggests against assessing for PAI-1 overexpression as part of a thrombophilia workup. While there is some data to suggest an association between PAI-1 polymorphisms and pregnancy loss, ALIFE2 s...
Would you consider prophylactic anticoagulation for May-Thurner syndrome in pregnancy if prior endovascular intervention has been completed?
In general, I have a very low threshold to initiate prophylactic anticoagulation in pregnancy. For a patient with a history of May-Thurner that has been endovascularly corrected and who has been maintained off of anticoagulation without issue, I would have a risk-benefit discussion about prophylacti...
How long would you anticoagulate a patient with recurrent VTE who has ongoing risk factors for intracranial bleeding?
In general, my preferred agent outside of the inpatient setting in patients with a risk of intracranial bleeding is LMWH. In the inpatient setting, utilizing a bivalirudin or heparin gtt is most appropriate. I would monitor carefully, including potentially imaging 24 hours after the therapeutic anti...
Can RT to non-bulky sites be omitted in an early stage (stage I or II) classical Hodgkin's lymphoma case with a CR by PET/CT?
Randomized studies have consistently demonstrated that combined modality therapy is superior to chemotherapy alone in regards to progression-free survival in early-stage Hodgkin lymphoma. The magnitude of the benefit varies across studies, but a relative risk reduction of ~50% can be expected which ...
