How would you approach management of bleeding risk and factor VIII replacement in a patient with severe hemophilia A undergoing stem cell transplant?
Same way as anyone with severe hemophilia: Prophy with QOD factor or weekly hemlibra Extra correction for procedures, trauma, or bleeding
What are your top takeaways from ASH 2022?
1. Late Breaking Abstract (LBA-1): Consolidation Therapy with Blinatumomab Improves Overall Survival in Newly Diagnosed Adult Patients with B-Lineage Acute Lymphoblastic Leukemia in Measurable Residual Disease Negative Remission: Results from the ECOG-ACRIN E1910 Randomized Phase III National Cooper...
How do you approach low to moderate titer of APLS when working up unprovoked DVT if it is persistent on repeat testing?
I have a low threshold to recommend long term (indefinite) anticoagulation for unprovoked thrombosis, regardless of whether there is positive APLS testing. I do agree with Dr. @Dr. First Last, however, that shared decision-making is important when committing a patient to prolonged anticoagulation, a...
Are there any possible scenarios where you would do phlebotomies for heterozygous hemochromatosis?
The answer is yes but unusual. Occasionally, a heterozygote or double heterozygote will be weakly phenotypically positive. If the ferritin and TSAT (on overnight fasting sample) are high, I will. I prefer that blood donation be used but if not an option, I will take it. The iron parameters must be...
What is the role of local control +/- whole lung irradiation in a patient with relapsed/refractory Ewing sarcoma to the hilum plus multiple lung nodules?
I would boost residual thoracic disease to at least the usual Ewings gross disease dose of 55.8 (total, including WLI dose). Doses in this range are well known to be safe in the thorax and this multiply relapsed disease is likely to be more treatment refractory than primary disease. SBRT boost seems...
How would you approach a low to moderate titer of one of the APLS antibodies in a patient with a strong family history but no personal history of thrombosis?
I do not do anything as there are no data to support intervention in this case.
Do you typically see peripheral neuropathy in patients with castleman syndrome?
Castleman's is a rare disorder. It has been associated with POEMS in which severe neuropathy is part of the syndrome, but is not as common an association as myeloma. But neurologists only see the patients who have neurologic symptoms. My brief look at review articles on Castleman's suggests that POE...
Do you switch from imatinib to another TKI in patients with chronic phase CML who develop renal insufficiency?
Imatinib has been associated with a decline in GFR. It is not certain (and probably doubtful) that this represents kidney damage. If no other causes can be identified, a change could be appropriate. Bosutinib has been associated with a similar decline so nilotinib or dasatinib might be better option...
Based on recently published data from COG ANHL12P1, how will you use crizotinib in pediatric and AYA patients with ALK+ anaplastic large cell lymphoma?
I would discuss brentuximab (plus ALCL chemo backbone) with newly diagnosed ALCL with patients and families in the absence of any open trials. The published COG data looks favorable but hasn't been shown in a randomized setting to improve EFS/OS. With the VTE data (and the availability of Brentuxima...
When patients develop headaches from luspatercept, do they tend to improve over time?
I've seen two common scenarios with this. One is headaches related to hypertension as a result of luspatercept. By treating the hypertension, the headaches often improve. If the headaches are in the absence of hypertension, I do use a low dose beta blocker to see if it helps, and have had some resul...
