How do you manage perioperative anticoagulation for a patient with a history of recent, surgically provoked VTE?
In most cases, bridging is rarely indicated because the bleeding risk usually outweighs the risk of VTE recurrence during a short (1–2 day) interruption of anticoagulation. However, after a recent VTE (defined as <3 months), the estimated risk of VTE recurrence is high (>15–20% per year) (still low ...
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...
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...
Would you give adjuvant radiation after complete resection of a small primary cutaneous follicular lymphoma of the scalp?
Not a lot of data, but here goes. First, one has to go back decades in the literature to find series of patients with lymphoma rx'd with surgical resection alone. In general addition of RT improved outcome even when ostensibly resected with neg margins. With today's technology risk of additional RT ...
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...
