How do you handle hypogammaglobulinemia detected in patients prior to maintenance rituximab infusion?
That is a good question. Adding on to Dr. @Dr. First Last's response, rituximab has been shown to cause hypogammaglobulinemia that can persist or worsen with ongoing therapy. In a study published by Barmettler and colleagues, 133 patients out of a cohort of 8633 patients had serum IgG levels checked...
Does the recent publication of EPCORE FL-1 (Epcoritamab + R2) change your preferred 2L SOC for R/R FL?
Partially! Epcoritamab certainly has a role in patients with FL who have more aggressive behaving disease but there is a plethora of choices in that setting. It may not be suitable for patients treated in the community away from my center because of the unique toxicities. It does have a role in that...
How do you manage anticoagulation/antiplatelet therapies with strong indications for uninterrupted therapy in setting of urgent procedures?
If anticoagulation is absolutely contraindicated because of the bleeding risk of the procedure, then "bridging" will usually make the most sense, most of the time, with low molecular weight heparin such as enoxaparin. If dual antiplatelet agents are contraindicated, particularly in the first month a...
How does pirtobrutinib compare to other available therapies for relapsed/refractory CLL after BTK inhibitor treatment, particularly in terms of efficacy and tolerability?
BRUIN trial enrolled patients with a median of 3 prior lines of treatment. The response rate with pirtobrutinib is close to 80%. However, overall PFS is about 1.5-2 years. So, most patients will eventually relapse after pirtobrutinib.It is possible that the use of pirtobrutinib in earlier lines of t...
Would involved site radiation therapy be recommended in a patient with POEMS syndrome whose myelopathy symptoms worsened after one cycle of CyBorD?
I would swiftly treat this patient with a common schedule, for instance, 5 x 4 Gy. I do not see any risk of concurrent rituximab.
How does the CLL17 trial presented at ASH 2025 change current practice guidelines?
The CLL17 study provides some tangential support for time-limited therapy in a subset of patients that I would consider now--those who have low-risk disease with IGHV mutated (non-3-21) and absent TP53 mutation or deletion. Here, we would expect patients to do quite well, and long-term follow-up exi...
For primary CNS lymphoma, when do you refer for whole brain radiation therapy (WBRT)?
When data are limited, consensus guidelines tend to rely on the personal clinical experiences of the guideline committee members. That may explain the NCCN guidelines. Recently, remarkable progress has been noted in the treatment of CNS lymphoma with drugs alone. Ibrutinib is particularly effective ...
How would you approach a referral for concern for hemochromatosis with ferritin elevation but otherwise normal iron studies?
Interesting questions, but lack of specifics about the degree of elevation and what constitutes normal iron studies makes it difficult to directly answer this question. However, there are well-recognized causes of elevated ferritin due to non-iron overloaded conditions, including increased apoferrit...
How would you approach the management of a patient with elevated iron saturation (60%) and ferritin (500s) with negative genetic testing for hemochromatosis?
I would approach this clinical scenario in the following manner: Always starting with good medical and family history first. Is there any history compatible with secondary hemochromatosis (i.e., history of blood or multiple iron transfusions)? Could the patient be tested for other non-282Y genetic ...
What is your treatment approach for MAG antibody associated polyneuropathy?
When patients have a classic Distal acquired demyelinating sensory (DADS) Neuropathy phenotype (by clinical +/- EDX criteria), typically an SPEP/IFE is checked first, and if an IgM monoclonal gammopathy is observed, then I typically check MAG antibodies at that point (if clinical and EDX features ar...
