Fig. 3From: HER2 gene (ERBB2) amplification is a rare event in non-liver-fluke associated cholangiocarcinogenesisSurvival analysis of CCA patients stratified for HER2 gene amplificationDisplayed are the survival curves for the HER2-negative patients (red curve) and the HER2-positive patients (blue curve) (n = 361). Median survival was nominally lower in the HER2-negative group (3.8 years) than in the HER2-positive group (6.9 years), though not statistically significant (p = 0.471)Back to article page
