To investigate the clinicopathologic characteristics and the prognostic impact of PIK3CA gene amplification in curatively resected esophageal squamous cell carcinoma (ESCC). Using 534 curatively resected ESCCs, the PIK3CA gene copy number was evaluated with fluorescent in situ hybridization. PIK3CA amplification was defined as PIK3CA/centromere 3 ratio is ≥ 2.0 or average number of PIK3CA signals/tumor cell nucleus ≥ 5.0. PIK3CA mutations in exon 9 and 20, encoding the highly conserved helical a ...[more]
