ABSTRACT
BACKGROUND & AIMS: The prognosis of biliary tract cancer (BTC) is poor. Standard treatment for advanced BTC is a chemotherapy (CT) with gemcitabine and cisplatin. Phase III evidence for a second-line (2L) CT is lacking. We aimed to investigate the feasibility of a 2L CT, to estimate the outcome and to identify prognostic markers. METHODS: Patients of our institution with advanced BTC between 2000 and 2015 receiving CT were included. Data were analysed in univariate and multivariate analysis. RESULTS: Three-hundred and fifteen and 144 patients (45.7%) received first-line (1L) and 2L CT respectively. The OS of patients receiving 2L CT was 16.67 and 9.9 months from the beginning of 1L and 2L CT respectively. The overall response rate and the disease control rate after 3 months were 9.7% and 33.6% respectively. Adverse events of grade 3 or more were observed in 26.1%. One patient died of gemcitabine-related haemolytic uraemic syndrome. Age of more than 70 years was not associated with a poor outcome. In multivariate analysis, CEA levels of >3 µg/L (P = 0.004, hazard ratio [HR] 1.89, 95% CI 1.22, 2.91), cholinesterase (CHE) levels of <5 kU/L (P = 0.001, HR 2.11, 95% CI 1.34, 3.31) and leukocytosis (P = 0.001, HR 2.90, 95% CI 1.51, 5.56) were associated with poor survival. CONCLUSIONS: Despite a relevant toxicity, our data suggest that 2L CT may be feasible in fit BTC patients. CEA elevation, leukocytosis and low CHE levels are unfavourable prognostic markers. Results from prospective randomized trials are urgently awaited.

PURPOSE: The purpose of this study was to identify prognostic factors of patients with intrahepatic cholangiocarcinoma (ICC) treated with resection and to investigate the effect of adjuvant chemotherapy (CT). METHODS: Patients with ICC diagnosed between 2000 and 2015 treated at Hannover Medical School were included. Clinicopathologic characteristics were analyzed in univariate and multivariate analysis. In a matched pair survival analysis, patients with or without adjuvant CT were matched by these prognostic factors. RESULTS: Two hundred and ten patients were included. Median survival was 28.7 months, 1-, 3-, and 5-year survival rates were 72.8%, 29.6%, and 14.1%, respectively. In multivariate analysis, lymph node involvement (p = 0.006, HR 1.84), larger tumor size (p = 0.013, HR 1.79), vascular invasion (p = 0.038, HR 1.70), and prolongation of prothrombin time (p < 0.001, HR 4.20) were significantly related to poor survival. Thirty-nine patients received adjuvant CT of which 60% had lymph node involvement. Each 25 patients with and without adjuvant CT were matched to the identified prognostic factors. The median survival of patients with adjuvant CT was 33.5 months, compared to 18 months in the control group (p = 0.002). The 1-, 3-, and 5-year survival rates were 96, 36, and 12%, compared to 60, 4, and 0% in non-treated patients. CONCLUSIONS: We identified several prognostic factors for patients with ICC treated with resection. Our data support the use of adjuvant CT in patients with ICC. The results of prospective randomized controlled studies will clarify the role of adjuvant CT in the future.
