RESUMEN

Intensive chemotherapy (IC) is commonly used to achieve remission in patients with acute myeloid leukemia (AML). Venetoclax plus azacitidine (VEN-AZA) is FDA-approved to treat patients with AML aged ≥ 75 years or who are ineligible for IC. This retrospective analysis used de-identified electronic health records from the US-based Flatiron Health database from patients diagnosed 11/21/2018 to 10/31/2021 to compare treatment outcomes with VEN-AZA vs. IC. Patients were 1:1 propensity score-matched ([Formula: see text]). Assessments included rates of complete remission (CR) and hematopoietic stem cell transplant (HSCT), overall survival (OS), and relapse-free survival (RFS). CR and HSCT rates were higher with IC than with VEN-AZA (60.9% vs. 44.2% [P = 0.006] and 18.1% vs. 8.0% [P = 0.012], respectively). Median OS was 17.7 months in patients treated with IC and 11.3 months with VEN-AZA without censoring (P = 0.278) and 13.7 vs. 10.6 months, respectively, with censoring at HSCT (P = 0.584). Median RFS was 12.0 months in patients treated with IC vs. 9.5 months with VEN-AZA without censoring (P = 0.431) and 6.4 vs. 7.4 months, respectively, with censoring at HSCT (P = 0.444). No OS or RFS differences observed between the two arms reached statistical significance. Randomized controlled trials comparing the two approaches are warranted, as are novel approaches to reduce relapse rates following CR.

RESUMEN

OBJECTIVES: This study aims to describe the use of patient-reported outcome measures (PROMs) in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) studies and the PROMs landscape. METHODS: A comprehensive literature review was performed in Medline/Embase (since 2000) and ClinicalTrials.gov (since 2013) to identify PROMs used in MDS and AML clinical studies. Additionally, PROMs included in approved drug labels since 2000 were reviewed. RESULTS: Overall, 112 different PROMs were used in 168 published MDS studies and 152 PROMs were used in 172 AML studies. From ClinicalTrials.gov, 16 different PROMs were used in 22 ongoing registered studies in MDS, and 24 were reported in 41 AML studies. The most frequently used PROMs were cancer-specific (eg, EORTC QLQ-C30, FACT-An) or generic (SF-36, EQ-5D) instruments, whereas MDS- and AML-specific instruments (eg, QUALMS and QOL-E in MDS; FACT-Leu and EORTC QLQ-Leu in AML) were used in a minority of studies. Two EMA-approved drugs for MDS included PROMs in their label. EORTC QLQ-C30 is by far the most frequently used cancer-specific PROM in both MDS and AML studies. CONCLUSIONS: This research indicated an underuse of AML/MDS-specific PROMs for these two indications in clinical studies and labeling claims. However, AML/MDS-specific instruments in development might be considered in future studies.

RESUMEN

BRAF and NRAS are common targets for somatic mutations in benign and malignant neoplasms that arise from melanocytes situated in epithelial structures, and lead to constitutive activation of the mitogen-activated protein (MAP) kinase pathway. However, BRAF and NRAS mutations are absent in a number of other melanocytic neoplasms in which the equivalent oncogenic events are currently unknown. Here we report frequent somatic mutations in the heterotrimeric G protein alpha-subunit, GNAQ, in blue naevi (83%) and ocular melanoma of the uvea (46%). The mutations occur exclusively in codon 209 in the Ras-like domain and result in constitutive activation, turning GNAQ into a dominant acting oncogene. Our results demonstrate an alternative route to MAP kinase activation in melanocytic neoplasia, providing new opportunities for therapeutic intervention.
