“New genomic study compares metastatic male breast cancer (MaBC) with female breast cancer (FBC) across all subtypes:
ER+/HER2-:
More alterations in GATA3 (26.2% vs. 15.9%), BRCA2 (13.8% vs. 5.3%), MDM2 (13.3% vs. 6.14%), CDK4 (7.1% vs. 1.8%).
Fewer mutations in TP53 (11% vs. 42.6%) and ESR1 (5.7% vs. 14.6%).
ER+/HER2+:
More variants in ERBB2 (22.7% vs. 0.6%), GATA3 (36.3% vs. 6.2%), MDM2 (36.3% vs. 4.9%). Fewer alterations in TP53 (9.1% vs. 61.7%).
Triple negatives:
Fewer alterations in TP53 (25% vs. 84.4%).
This study reveals significant genomic differences between MaBC and FBC. These differences may affect how tumors respond to treatments, suggesting that therapies should be tailored specifically for each gender to be more effective.”
