Are there any alternative, hypofractionated RT courses for patients with DLBCL that can be used during the COVID-19 pandemic?
ILROG recently came out with guidelines pasted below: Synopsis of ILROG Recommendations for Administering Radiotherapy for Hematological Malignancies During Emergency Conditions of the COVID-19 Pandemic • We are facing an increased demand for RT to substitute or complement systemic therapy deemed i...
How would you treat AML in a pregnant patient at 12 weeks' gestation?
My answer is under the assumption that, after a multi-disciplinary discussion with the patient, oncology/leukemia team, and maternal fetal medicine, the objective is to initiate AML-directed therapy while maintaining the pregnancy. The highest risk of deleterious impact to the fetus from chemotherap...
Do you offer enasidenib with azacitadine in AML with an IDH2 mutation for patients ineligible for intensive induction chemotherapy?
I typically do not give enasidenib with azacitidine upfront for patients with AML with IDH2 mutation and ineligible for intensive induction chemotherapy. Based on the results of the VIALE-A study (DiNardo et al, NEJM 2020), I usually give venetoclax with azacitidine to those patients. In addition to...
For iron deficiency anemia due to heavy menstrual bleeding, what is your preferred method of controlling heavy menses?
Thanks for this important question. Too often, we see women in hematology clinics who have had terrible bleeding for years, and the menorrhagia has not been addressed, only the iron deficiency. From a hematology perspective, I make sure to do an ISTH bleeding score assessment to see if she needs to ...
In patients with inflammatory arthritis (RA, psoriatic arthritis) and a history of MGUS are there any concerns regarding use of biologics?
There is no absolute contraindication to any particular biologic used to manage active RA in a patient with MGUS. The literature does point out a small potential risk associated with tocilizumab in terms of development of myeloma influenced by the IL-6 pathway (and I would tend to extend that potent...
What is your approach to managing iron overload in children with transfusion-dependent beta thalassemia who have adherence challenges or toxicity with standard chelation regimens?
I would divide the adherence issues into two populations. The younger children where a caregiver is responsible for administering the chelation, and adolescents where caregivers have passed on the responsibility to the patient. For the former, adherence is reinforced with an explanation of the possi...
At what lab values (ferritin, TSAT%) would you offer IV iron therapy to patients with restless leg syndrome?
1. I am hopeful that practitioners will start understanding that ferritin alone is not enough to assess iron because of its acute phase reactivity. I like to order iron parameters after a 5-9 hour fast so the serum iron is not speciously elevated and get a ferritin and TSAT. If the ferritin is <30 a...
For atrial fibrillation patients with high risk of CVA who cannot tolerate full dose AC due to bleeding, do you consider low dose/extended dosing anticoagulation even if they do not meet age/GFR criteria for a dose reduction, if Watchman is not readily available as an option?
Most drugs, including anticoagulants, have a dose-response. Therefore, one could argue that even though DOACs were not studied at low doses, except in defined sub-groups such as the very elderly, using such a dose in other situations may have some benefit. The problem is that without data, we simply...
What GDMT do you recommend for patients with AL amyloidosis and systolic heart failure?
You are correct that cardiac amyloidosis patients do not tolerate most of the GDMT. SGLT2i may be helpful for both diuresis as well as HFpEF, and we do try to start this. Generally, they do not tolerate ARB/ACEI or even beta blockers. We find that torsemide seems to have better GI absorption and thu...
How do you decide whether to hold acalabrutinib or zanubrutinib in patients with indolent B-cell lymphoma/leukemias in a perioperative/periprocedural setting?
This is always a point of discomfort among providers, but it can actually be made quite easy. BTK inhibitors have known antiplatelet effects similar to low-dose aspirin. Consequently, if the surgeon holds aspirin for the planned procedure, I generally recommend that we hold the BTK inhibitor for 3 d...
