Does discovery of clonal hematopoiesis on liquid biopsy for solid tumors change your treatment approach in terms of which chemotherapy to offer for the solid tumor?
CHIP findings are relatively common. A small percentage of patients with CHIP abnormalities will evolve into a Hematological malignancy depending on the mutation in the 1-2% range. I am unaware of any data that indicates that this percentage increases due to treatment for solid tumors. Therefore, I ...
Does cytoreductive therapy in high risk PV reduce thrombotic events because of better normalization of blood counts as compared to phlebotomy, or through some other mechanism?
I suspect that several factors contribute to the decrease in thrombotic events. First, more consistent normalization of blood counts. However, probably more importantly is the reduction in inflammation. This would be supported by the lower thrombotic events in patients on ruxolitinib vs standard the...
What is the typical time course of cytopenias after CAR-T therapy, and how do you treat them?
There are no specific guidelines but most patients will have some degree of count recovery week 4-6 but albeit not always the strongest recovery.Management of neutropenia varies widely from institution to institution with regards to utilization of GCSF. Some places will start it in a prophylactic ma...
How would you manage a patient with history of follicular lymphoma treated with Bendamustine-Rituximab who now has a new FDG avid lesion that is biopsy proven CD30 positive CD20 negative DLBCL?
Certainly an unusual and challenging situation, and one that raises multiple questions. How long ago was the rituximab - is the CD20- status "true" or might it be a false-negative in the presence of blocking antibodies? Is it really totally negative or rare/dim?But taking at face value that the dise...
Is there experience/reports of using voxelotor in sickle cell patients who are Jehovah Witnesses with few crises but who have fatigue and/or dyspnea?
I would not hesitate to use voxelotor in most patients with sickle cell anemia, including Jehovah's Witnesses, if they have not responded to hydroxyurea with near cessation of acute vasoocclusive events and have continued hemolytic anemia. Voxelotor usually reduces hemolysis that results in an incre...
What is your preferred approach for patients with anti-phospholipid syndrome with recurrent thrombosis on coumadin and LMWH?
This is a difficult condition to manage and personalized approach/risk stratification is key. There are several potential considerations:Warfarin therapy could be intensified, anti-platelet agents could be considered (although not in combination with LMWH).For patients with an underlying autoimmune ...
Do you routinely check for copper deficiency as part of workup for bicytopenia with leukopenia/anemia or pancytopenia?
I do not usually check for this but not unreasonable if there is a clinical reason to check.
In patients with thrombocytosis with negative MPN workup from peripheral blood and bone marrow, is there a role for daily 81mg aspirin or other treatment?
In the absence of an MPN, there is no data to support the use of low-dose ASA. Unless there was extreme thrombosis and acquired von Willebrand syndrome, there would also be little reason to bring the platelet count down as well. In the absence of MPN, thrombocytosis itself is not a risk factor for t...
In what situations would you offer salvage radiotherapy for relapsed/refractory DLBCL?
There are a number of different clinical scenarios when I would consider RT in patients with relapsed/refractory DLBCL. NCCN guidelines (page BCEL-7 and BCEL-8) list RT as an option in several of these settings.1. Relapsed disease s/p autologous or allogeneic stem cell transplantation - In patients ...
When would you consider stopping chronic transfusion therapy in a sickle cell patient with history of abnormal TCDs but no stroke?
Fortunately, we have good data to answer this question. The TWiTCH trial aimed to determine the efficacy of hydroxyurea at maintaining TCD velocities after discontinuation of initial transfusion therapy to prevent primary stroke. Patients on this non-inferiority trial with a history of abnormal TCD ...
