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 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...
What is your approach to pregnant patients with type 2B von Willebrand disease, particularly when thrombocytopenia is already present?
The gist of this challenging clinical problem is that the high estrogen levels in the third trimester of pregnancy raise the VWF level normally. In type 2B VWD, this effect raises the level of the abnormal VWF, which clears more platelets from the circulation, and can lead to severe thrombocytopenia...
What radiation doses and subsequent treatment monitoring would you recommend for multiple myeloma patients with multifocal bony lesions who decline chemotherapy?
Systemic therapy is the cornerstone of treatment for multiple myeloma, and the vast majority of patients initiate an appropriate regimen upon diagnosis. Occasionally, patients will have very limited disease and will be referred to Radiation Oncology for consideration of local therapy to delay the ne...
How do you manage anemia associated with belzutifan therapy?
Anemia is a common toxicity with belzutifan. In a recent pooled safety analysis (Choueiri et al., The Oncologist KCRS Meeting 2024), anemia was seen in 84% of patients (any grade; 29% grade 3) with a median time to onset of 29 days. It is an on-target effect resulting from HIF regulation of erythrop...
In a patient with high risk acute promyelocytic leukemia, when do you consider ATRA+ATO with GO vs ATRA+ATO with idarubicin?
Given the recent publications with ATRA/ATO and GO in high risk patients or low risk patients who develop leukocytosis (Blood 2017) and the long term follow up of the comparative study form the NCRI AML Working Group (Blood 2018), GO is my preference in all cases unless there is hepatic toxicity or ...
How would you treat a patient with two concurrent plasmacytomas whose bone marrow showed no evidence of multiple myeloma and has no other MM defining features?
This is by definition Multiple Myeloma and I would treat it as such with systemic induction chemotherapy followed by transplant. These patients do better than the standard MM oftentimes. IMWG Criteria for the Diagnosis of MM | Inl Myeloma Fn
What is your escalation strategy for chronic GvHD?
There are now several available options for steroid resistant cGVHD. The old standbys - ECP and rituxan are useful in about 30% of patients. Ibrutinib was the first new drug to get FDA approval. Unfortunately, I don't think the real-world experience is anywhere near as good as the trial (Chin et al....
Will you use vadadustat in place of an ESA in treating anemia of chronic kidney disease?
Vadadustat is approved by the FDA only for patients who have been on dialysis for at least 3 months. It is not approved for patients with CKD not on dialysis. Its efficacy and safety are comparable to that of ESAs. I would consider using vadadustat in two patient populations: those on home dialysis ...
