CYP2A6 Genotypes Affect Survival in Pancreatic Cancer Patients

Decreased-function CYP2A6 genotypes correlate with worse outcomes for pancreatic cancer patients on S-1 therapy.

• 56.6% of patients had decreased-function genotypes, increasing lymph node metastasis (78% vs. 52.4%, p=0.001).
• Median recurrence-free survival was significantly shorter for poor metabolizers (19.2 months vs. 32.3 months, p=0.040).

Understanding genotype impact may guide treatment personalization and improve patient outcomes.

• Poor metabolizer status was linked to a 3.17 times higher risk of reduced overall survival (p=0.039).
