Abstract
For older unfit patients receiving venetoclax-based induction, data on the significance of interim bone marrow biopies (BMBx) findings on clinical outcomes is lacking. We retrospectively evaluated interim BMBx results performed on Cycle 1 days 21-28 of venetoclax-based therapy in 69 adults with myeloid malignancies to determine whether blast clearance was associated with overall survival (OS) and overall response rate (ORR). Median age was 75 years (range 69-78). Results demonstrated blast reduction (BR, <5% blasts) in 71%. Venetoclax was held to allow count recovery in 86% of these patients. Achieving interim BMBx BR was significantly associated with OS (p = 0.0033) and ORR (Cohen's kappa 0.39). Patients whose venetoclax was held experienced low rates of infection and reduced cytopenias. These findings support the importance of cycle 1 BMBx assessment during venetoclax-based therapies, specifically in predicting which patients will achieve optimal outcomes and in mitigating toxicity.
期刊介绍:
Leukemia & Lymphoma in its fourth decade continues to provide an international forum for publication of high quality clinical, translational, and basic science research, and original observations relating to all aspects of hematological malignancies. The scope ranges from clinical and clinico-pathological investigations to fundamental research in disease biology, mechanisms of action of novel agents, development of combination chemotherapy, pharmacology and pharmacogenomics as well as ethics and epidemiology. Submissions of unique clinical observations or confirmatory studies are considered and published as Letters to the Editor
