For pediatric patients with iron overload (high ferritin and transferrin saturation), do you perform HFE screening first, or proceed to non-HFE gene sequencing upfront to evaluate for HJV mutation as well?
Because there is no recommended "screening" scenario for iron overload in pediatrics (especially with no family history), the question for me revolves around "why did the patient get tested in the first place?" If it were a routine screen for iron deficiency, which affects millions of children at an...
How do you approach management of a patient with mast cell leukemia?
Mast cell leukemia (MCL) is a rare and aggressive subtype of systemic mastocytosis defined by ≥20% mast cells in the bone marrow aspirate. A recent multicenter analysis of 92 patients with MCL had a median overall survival (OS) of 1.6 years. Midostaurin was the most common first-line therapy (45% of...
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...
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.
