What are the factors that you would consider for the use of ESA in patients with anemia of CKD with a history of stroke or TIA?
Large clinical trials of ESA have indicated increased stroke risk with these medications with TREAT reporting the highest stroke incidence. In this study, "baseline history of cerebrovascular disease was a strong predictor of experiencing a stroke during follow-up; patients with a history of stroke ...
How would you treat an older patient with B symptoms and biopsy consistent with grade 3 follicular lymphoma but noted to have a PET scan with SUV readings of > 20?
If an adequate biopsy was performed of the most active (high SUV) mass/node and results as follicular grade 3 A, then can treat as you would a follicular lymphoma with BR. I have seen high SUVs with follicular lymphoma. Mir et al., PMID 31961926However, if it is follicular grade 3 B or has high Ki67...
What is your first line of therapy for refractory Hodgkin lymphoma in an AYA patient?
Our first approach in this setting is second line chemotherapy with the intention to achieve a complete metabolic remission (by PET) and then an autologous stem cell transplant. Our approach to the transplant includes total lymphoid irradiation followed by a conditioning regimen of Cyclophosphamide,...
How would you approach a patient with early-stage orbital MALT lymphoma with high proliferative index?
High proliferative index is uncommon in MALT lymphoma, seen more often with high grade histologic variants. For localized disease, it would not influence my management recommendations. For orbital MALT lymphoma, 24 Gy in 2 Gy fractions to the orbit. Efforts to shield part of the orbit should be unde...
Is there a role for DOAC use for patients with unprovoked PE, that have had recent sleeve gastrectomy with duodenal bypass?
Alterations in the gastrointestinal (GI) tract following bariatric surgery, as well as altered or reduced oral intake, have the potential to impair the absorption of both DOACs and VKAs in the acute setting. DOACs are absorbed in the upper GI tract, which is altered by the most common bariatric surg...
What is your approach to optimizing pre-operative hemoglobin in patients with sickle cell disease?
Unfortunately, I am not aware of a more comprehensive document than the ASH guidelines. These are what I use to define my default management strategy, often in coordination with our dedicated hematology consult subspecialist service.
How would you evaluate a patient with an isolated high RBC count but with a normal hemoglobin and hematocrit?
My first question would be, how long has the elevated red cell count been present? I ask this because, in a study of 10,000 individuals, erythrocytosis was initially found in 88 but after a year only 11 still had this finding (Ruggeri et al., PMID 13679323). If therefore, the observation is recent, ...
Would you extend the duration of anticoagulation in patients with a provoked DVT, but evidence of residual clot at 3 months?
This is a really interesting discussion. I do tend to get Dopplers at the end of the anticoagulation treatment period, but only to assess the new baseline and to help decision-making in the future if they develop new symptoms and have another Doppler. I find this to be very helpful to understand if ...
In patients with post-PV myelofibrosis who are ineligible for allogeneic stem cell transplant, how do you approach symptomatic splenomegaly refractory to splenic radiation and ruxolitinib?
This is always a tough situation. First, I would make sure the patient is truly not a candidate for transplant. With reduced intensity conditioning and the addition of ruxolitinib before and after transplant, transplant is better tolerated than it once was. Otherwise, would consider switching to ano...
How would you approach management and monitoring of AL amyloidosis with isolated renal involvement?
This is tough for sure, and my first question would be to ask how the renal biopsy was determined to be AL amyloidosis. Sometimes typing isn't required if the pattern is overwhelmingly lambda-restricted or kappa-restricted by immunofluorescence... but in this case, mass spectrometry typing may be wo...
