Text: Multivariate analyses showed that high ERCC1 expression [HR 1. 37 ; 95 % confidence interval (CI) 1. 08-1. 75 ; P = 0. 010], performance status 1 (HR 1. 45 ; 95 % CI 1. 13-1. 86 ; P = 0. 004), and number of metastatic sites 2 (HR 1. 66 ; 95 % CI 1. 28-1. 86 ; P < 0. 001) were associated with a poor prognosis, and recurrent disease (versus unresectable ; HR 0. 75 ; 95 % CI 0. 56-1. 00 ; P = 0. 049) was associated with a favorable prognosis.
