Liver toxicity was assessed using the Common Terminology Criteria for Adverse Events, version 4.0. Progression-free survival and overall survival were assessed using the Kaplan-Meier and log-rank methods.RESULTS: Of 261 patients, 34 (13%) had developed liver toxicity after a median of 29 days (range, 5-155 days). Grade 4, 3, and 2 alanine aminotransferase or bilirubin had increased in 2 (6%), 17 (50%), and 8 (24%) patients, respectively.

The UGT1A1 polymorphism was associated with improved median progression-free survival (TA6/TA6, 5.5 months; TA6/TA7, 34.2 months; TA7/TA7, 22.3 months; unknown UGT1A1 status, 9.2 months; UGT1A1 polymorphisms combined vs. unknown status, P = .021). UGT1A1 polymorphism was associated with improved median overall survival (TA6/TA6, 8.1 months, TA6/TA7 or TA7/TA7 not reached, unknown UGT1A1 status, 16.6 months; UGT1A1 polymorphisms combined vs. unknown status, P = .033).
