Abstract

Aim: While first-line palliative chemotherapy (CT1) improves survival and quality of life in advanced biliary cancer (ABC), there is no randomized evidence to support second-line chemotherapy (CT2) in ABC. We aim to explore to role of CT2 in ABC. Methods: We performed a retrospective review of all patients who received one or more lines of chemotherapy for ABC at four Australian cancer centers between 2008 and 2011. A Cox proportional hazard model was developed to determine the impact of clinicopathologic variables on overall survival (OS) from time of progression on CT1. Results: We identified 73 patients who received palliative chemotherapy for ABC. Twenty-five patients (34%) received two or more lines of chemotherapy. Patients with a preserved performance status on progression on first-line chemotherapy (CT1) were more likely to receive second-line chemotherapy (CT2) (P < 0.001). Disease control rate with CT2 was 36%, and mean progression-free survival was 3.2 months (95% confidence interval 1.5-4.9 months). The following variables were significant in the univariate analysis of OS from time of progression on CT1: lines of chemotherapy (P = 0.0001), Eastern Cooperative Oncology Group performance status at progression on CT1 (P < 0.0001) and disease control with CT1 (P = 0.027). Lines of chemotherapy received and performance status remained significant in the multivariate analysis for OS from progression on CT1. Conclusion: Second-line chemotherapy is feasible in a subset of patients with ABC. Even after accounting for confounding variables, CT2 appears to increase OS in ABC, although we are unable to exclude other unmeasured factors such as tumor biology. These findings warrant further evaluation with prospective trials.
