Have you utilized a dose-reduced approach for elderly patients receiving frontline Pola-R-CHP, similar to R-miniCHOP?
I have utilized a dose-reduced approach for Pola-R-CHP for patients who are elderly, whom I would normally treat with R-miniCHOP, based on the early safety data from the POLAR BEAR trial. This randomized trial compared pola-r-miniCHP to R-miniCHOP in patients >80 years of age or >/=75 with comorbid ...
What is your approach to cancer patients who inquire about alternative or complementary treatments?
It depends a little bit on what specifically they want to use, and if they are truly investigating alternative medicine or complementary medicine. For people seeking full alternative medicine without any conventional treatment, I tell them that a research study showed that people who pursued the alt...
What guides your choice between prophylactic, intermediate, and full therapeutic dosing of enoxaparin in a woman with APLS and prior fetal loss with no hx of thromboembolic disease?
First, it is essential to confirm that patients meet criteria for obstetric antiphospholipid antibody syndrome (OAPS), based on the 2023 ACR/EULAR classification criteria. This includes persistently positive laboratory criteria (confirmed on repeat testing >12 weeks apart), plus otherwise unexplaine...
Do you consider co-prescribing hormone therapy and anticoagulation in a patient with prior DVT and uncontrollable VSM uncontrolled by non-hormonal therapies?
While I agree that you need to be thoughtful about adding additional VTE risk to patients with a history of VTE, I am much less concerned when patients are already on full-dose anticoagulation. Especially when the medication is transdermal estrogen, which has the lowest effect on thrombotic risk. I ...
What is your approach to AYA patients with B-cell ALL who relapse after CD19 CAR-T?
This is a somewhat nuanced question based on when the patient relapsed after CAR-T, what CAR-T product they received, whether the patient prior received hematopoietic stem cell transplantation (HSCT), other salvage therapies that were prior received as well as number of prior relapses. Multiple stra...
Do you perform genetic testing when patients have persistent hypogammaglobulinemia after rituximab therapy?
I would not routinely perform genetic testing. Multicenter studies (Labrosse et al., PMID 33862010; and Otttaviano et al., PMID 35892275) show that genetic testing returns a low yield, <5%. Several authors suggest that the risk of persistent hypogammaglobulinemia due to PID is increased if there is ...
How would you work up a patient with cutaneous mastocytosis?
In adults, consider mastocytosis as being systemic until you prove it is not. A single normal or low-elevated tryptase does not eliminate the possibility of systemic mastocytosis. All patients should go to Heme/Onc for consideration of bone marrow biopsy and ideally high-sensitivity PCR to look for ...
What is the utility of a hypercoagulability workup in recurrent cryptogenic stroke, and what specific tests would you recommend?
Ambulatory monitoring for AFib is probably more helpful than such a thorough clotting workup.
What induction regimen would you consider for KMT2A-rearranged AML in a young patient with multiple medical co-morbidities who is ineligible for clinical trials?
Given the mention of medical comorbidities and ineligibility for trials, I am going to assume that the patient cannot be treated with an intensive induction regimen. With this in mind, a lower-intensity approach such as azacitidine + venetoclax would be my recommendation. Survival outcomes in adult ...
Does anyone utilize P2Y12 assays to determine if clopidogrel may be ineffective when used for DAPT?
Yes, I use P2Y12 assays in two distinct settings. Medical management: If a patient on clopidogrel mono/dual therapy has disease progression with ICAD or experiences a recurrent ischemic event, I obtain a P2Y12 assay to assess responsiveness. This helps guide the decision to switch to ticagrelor and ...
