For low/intermediate essential thrombocythemia not on cytoreduction, would you temporarily cytoreduce in anticipation of surgery?
First, I am going to answer this question with a question. What is low/intermediate essential thrombocytosis (ET)? I ask this question because we are living in the 21st century in the midst of the genomic era, and it is far past the time that we should be dwelling on phenotype instead of employing p...
What are your top takeaways in Classical Hematology from ASH 2025?
My top 3 takeaways in classical hematology:1) ITP - much controversy at the education program session about the draft 2025 guidelines, where TPO mimetic + steroids is going to be recommended in the front line. There does not appear to be compelling new data that supports the revision of this guideli...
Should other treatment options be considered for MALT lymphoma if the lacrimal gland will be included in the radiation field in a patient with Sjögren's disease?
The orbit is the second most common site of origin for extranodal marginal zone lymphoma (MZL). Involved orbital structures include the bulbar and/or palpebral conjunctiva, lacrimal gland, and periorbital soft tissues. Patients with Sjögren’s syndrome (SS) are at increased risk for developing extran...
For biopsy proven extranodal marginal zone lymphoma involving two small bilateral lung nodules, would you consider definitive treatment to both nodules with radiation therapy?
It has been observed that many patients treated with radiation therapy for an extranodal MZL in a paired organ (orbital and parotid, in particular) will develop metachronous disease recurrence in the contralateral organ (Goda et al., PMID 20564130). In fact, it is relatively common for patients with...
For stage III-IV Hodgkin's lymphoma, would you consider consolidative radiation for bulky disease after a complete response was seen using N-AVD per the S1826 trial?
I would offer consolidative radiation only for PET-positive residual disease.
Do you continue to check tryptase levels in your patients with idiopathic anaphylaxis despite normal levels >5 on repeated checks?
Baseline serum tryptase levels have been reported to be quite stable in the vast majority of patients, but can vary more in people with HaT or mastocytosis. With a bST <8 ng/ml, there is no obvious reason to continue to check it. However, even with normal bST, the Practice Parameters recommend furth...
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...
