How would you approach anticoagulation for a patient with acute bilateral pulmonary emboli related to malignancy, but with a concomitant cavitary lung mass experiencing episodic, small-volume hemoptysis?
This is an interesting question to which we need to apply the art of medicine, weighing the risks and benefits of treatment. The major fatal events in this exact scenario are: Recurrent PE from undertreatment. Sudden massive hemoptysis after aggressive anticoagulation. The physician's management s...
How do you decide between anticoagulation and observation for an incidentally detected subsegmental pulmonary embolism in elderly patients with a history of gastrointestinal bleeding?
We face this conundrum not infrequently because subsegmental emboli are subject to high inter-reader variability, and the accuracy of the finding in isolation is suspect (Batayneh et al., Blood 2023). I once mentioned this to a radiologist who reads CTAs and was told, tactfully, that I was full of i...
Would you consider restarting IMID therapy in a patient with recent stroke while on IMID?
This is a very good question, and practice likely differs across institutions as data is limited. The discussion below refers primarily to the immunomodulatory (IMID) agents lenalidomide and pomalidomide.As you are aware, IMID therapy is known to be associated with an increased risk for venous throm...
How do you approach ADT in patients with high-risk prostate cancer who have risk factors for VTE, such as Factor V Leiden?
My default recommendation for patients with localized, high-risk prostate cancer is to recommend the use of long-term ADT. This intervention seems to offer a relatively large, clinically significant OS benefit for patients in the modern era receiving dose-escalated ADT. This benefit has been observe...
Do you utilize D-dimer to inform anticoagulation duration in the treatment of VTE?
I had developed a policy during my last eight or ten years of practice evaluating how long patients should be treated after a thrombosis and I'd like to share some impressions over these years as well as conclusions that I reached. These conclusions formed the basis of my approach to this problem. I...
What are your top takeaways in Hematologic Malignancies from ASH 2025?
The PARADIGM study is a very important one that may result in a paradigm change for the treatment of AML. The study showed that outcomes are equal or better with AZA + VEN among patients with AML suitable for intensive chemotherapy. The efficacy was superior in response rate and EFS (but not overall...
Do you routinely stop ESA when starting myelofibrosis patients on JAK inhibitor therapy?
The management of myelofibrosis with anemia is becoming increasingly nuanced, given the several JAK inhibitors available to us and the potential for add-on therapies! An excellent resource to consider regarding decision-making is Jain et al., PMID 39808793. Regarding this specific question at hand, ...
How do you approach the outpatient management of bispecific antibody therapy for hematologic malignancies?
Multiple bispecific antibodies (BsAbs) targeting CD20 on lymphoma cells and CD3 on T-cells are now available in follicular and large B-cell lymphoma. A multi-disciplinary team with knowledge of the different BsAb indications and possible toxicities is an important aspect of safely administering thes...
How do you manage the side effects of ropeginterferon alfa 2b for polycythemia vera patients?
Great question. Although ropeginterferon is better tolerated than other interferons, it is still associated with adverse events. If counts are controlled, I would recommend lowering the dose or spacing out the dosing interval, as that usually helps. For flu-like symptoms, I recommend pre-emptive man...
Can post op RT be omitted in a surgically repaired pathological fracture site in multiple myeloma if the patient will receive systemic therapy?
For extremities (e.g., the femur), if the pain is largely from structural instability, which resolves after surgical stabilization, then proceeding with systemic therapy without post-op RT would be very reasonable. On the other hand, if the patient is having persistent pain after surgery from the os...
