When treating a patient with classic early stage diffuse large B-cell lymphoma (Stage I/II), when is it appropriate for patients to receive 3 versus 6 cycles of R-CHOP chemotherapy when the treatment is followed by ISRT?
The SWOG 8736 study included patients with stage I (bulky or non-bulky) and nonbulky stage II aggressive non-Hodgkin lymphomas (mostly DLBCL). Bulky was defined as a mediastinal mass >1/3 maximal chest diameter or any mass > 10 cm. Patients were randomized to 8 cycles of CHOP or 3 cycles of CHOP + R...
How do you manage anxiety in patients prior to bone marrow biopsy procedure in the clinic?
With the use of the drill procedure for bone marrow biopsies, my experience is that the pain element of this procedure has essentially been eliminated. Prior to this, we offered conscious sedation, when possible, to our patients because of the painful nature of the biopsy procedure, which is not aba...
What is your approach to systemic anticoagulation for patients with hypoalbuminemia and nephrotic syndrome secondary to a non-membranous nephropathy condition?
Patients with nephrotic syndrome (NS) and hypoalbuminemia have a several-fold higher risk of venous thromboembolism (VTE) than the general population and also a somewhat higher risk of arterial thromboembolism (ATE), such as MI and stroke. This risk seems to be higher in membranous nephropathy (MN) ...
How do you decide whether to use pharmacologic VTE prophylaxis in hospitalized patients with decompensated cirrhosis?
For all patients, I begin by using a standard risk prediction tool to determine if the patient is appropriate for pharmacologic VTE prophylaxis. At our institution, the Padua risk prediction tool is embedded in our electronic health record/admission set. Clinical guidelines- including those from the...
Do you consider bleeding risk in elderly, frail patients with atrial fibrillation to be similar for all NOACs?
I believe that apixaban carries a lower risk of bleeding, with particular reference to GI bleed, when compared to rivaroxaban and dabigatran. This is true in the population of AF patients at large and most probably in frail patients as well.
How do you approach the outpatient management of bispecific antibody therapy for hematologic malignancies?
Multiple bispecific antibodies (BsAbs) targeting CD20 on lymphoma cells and CD3 on T-cells are now available in follicular and large B-cell lymphoma. A multi-disciplinary team with knowledge of the different BsAb indications and possible toxicities is an important aspect of safely administering thes...
How would you manage relapsed DLBCL in a patient who received second line CD19 CART treatment?
With commercial CD19 CAR-T therapy moving into earlier lines of therapy, post-CAR-T relapses are now more common. There are still many options depending on what first-line/bridging therapy was given, CD19/20/30 expression, and patient preferences. I always get a biopsy if feasible to confirm relapse...
What initial workup do you perform when there is a concern for porphyria?
This is a terrific question. But a broad question. Porphyria refers to a defect in heme biosynthesis leading to the accumulation of porphyrins and porphyrin precursors. We should remember that there are three general categories of porphyria based on clinical manifestations: acute hepatic porphyria (...
When would you opt for a chemotherapy free approach in the first line treatment for hairy cell leukemia?
This is an outstanding question and there are a few reasons to consider treatments other than cladribine or a chemotherapy-free approach. I have considered and used alternatives in special situations, mostly those with infections. I will limit this to the treatment of classic hairy cell leukemia as ...
Has your practice changed to PLEX-free initial therapy for iTTP?
I am not. The reason is that caplacizumab is not on formulary at my institution, and so implementing PLEX rapidly while obtaining caplacizumab (which typically arrives in 24-48 hours) is my current practice. If I had caplacizumab on formulary, I would utilize it as it was utilized in the MAYARI tria...
