Does 4G/5G polymorphism in the plasminogen activator inhibitor (PAI-1) gene increase the risk of thrombosis?
Venous thromboembolism (VTE) is a classical example of a multifactorial disorder where genetic and environmental factors interact to result in VTE. Of the genetic disorders, in isolation, many are weak risk factors but when combined with other genetic or one or more environmental risk factors increa...
Is there any benefit of using aspirin to mitigate VTE risk in testosterone-induced polycythemia?
Erythrocytosis is a common adverse effect of testosterone therapy, and results from several studies suggest an association between elevated hematocrit (Hct) and risk of VTE (Braekkan et al., PMID 19833630; Ory et al., PMID 35050717). There is currently no data to support the routine use of aspirin o...
What level of 24h urine M protein do you consider to define active myeloma in a patient with renal insufficiency, proteinuria and monoclonal gammopathy?
When in doubt, a renal biopsy is preferred to define what is the exact disease process leading to renal dysfunction. If cast nephropathy is seen, this supports a diagnosis of myeloma. If amyloid or light chain deposition disease is seen, this also supports a diagnosis of amyloidosis or MGRS/myeloma,...
How do you manage copper deficiency?
Copper supplements are available. Would need to exclude zinc excess as a cause and to discontinue zinc supplements.
What factors do you consider when choosing between asciminib vs TKI in a newly diagnosed CML patient?
I think any patient is a good candidate for asciminib, with the exception of those with atypical transcripts (e.g., b2a3, b3a3). The decision would mostly depend on the goals of the patient and the availability and access. Asciminib is particularly well suited for patients who would be interested in...
How would you manage a pre-menopausal woman with extranodal marginal zone lymphoma confined to the bladder wall?
Marginal Zone Lymphoma (MZL) when localized is curable in most instances with modest doses of RT (24-30 Gy), perhaps even less when the primary site is the orbit. It typically responds to rituximab but relapses occur in most cases. Therefore, definitive RT is the treatment of choice in the great maj...
For primary MZL of the breast, do you do whole breast to 24 Gy or ISRT?
Without knowledge of the age of this patient and whether the concern of carcinogenicity from half the normal dose of traditional whole breast radiation (which we obviously do all the time for breast cancer) is enough to warrant omission of curative intent therapy in what is otherwise described as a ...
Is there a role to continue aspirin in patients with myeloproliferative disorders who have never had a thrombotic event that are starting DOAC for stroke prophylaxis with newly diagnosed atrial fibrillation?
Aside from treating erythromelalgia, transient ischemic attacks (TIA) such as ocular migraine or documented atherosclerotic disease, aspirin has no role in the management of the MPN, despite the widely published recommendations for its use, particularly in so-called "high risk" polycythemia vera (PV...
What are your top takeaways in Hematology from ASCO 2025?
I would say: CARTITUDE-1 updates – first time we are seeing a plateau in a MM trial, that too in the relapsed/refractory setting with 5+ years follow-up. JNJ-5322 Trispecific – dual antigen targeting with less frequent dosing; 100% response rate in BCMA/GPRC5D naïve relapsed/ref MM patients; safety...
When would you treat mild anemia from low testosterone in an older male?
The primary indication for testosterone treatment is symptomatic hypogonadism and not anemia. Given the risk for adverse events in terms of erythrocytosis, cardiovascular events, and potential prostate diseases, the risk of providing testosterone for asymptomatic, mild anemia outweighs its benefits,...
