Description
In colorectal cancer, PIK3CA mutations were associated with reduced relapse-free survival in stage II/III patients (HR:2.587, 95% CI:1.108-6.039, P=0.0280, univariate analysis; HR:2.478, 95% CI:1.028-5.973, P=0.0433, multivariate analysis) and reduced disease-specific survival in patients of any stage (n=18 vs. n=140, P=0.0357) compared to wildtype PIK3CA.
