Prognostic Factors for the Selection of Patients Eligible for Second-Line Chemotherapy in Advanced Biliary Tract
Background:
The efficacy of second-line chemotherapy (CT2) after the failure of first-line chemotherapy (CT1) for advanced biliary tract cancer (BTC) has not been established. We investigated the favorable prognostic factors for CT2 to determine which patients could be expected to benefit from CT2.
Methods:
From a total of 168 patients who were treated with chemotherapy at our institution between January 2003 and December 2012, we retrospectively reviewed 50 patients who received CT2. Patients were treated with various chemotherapeutic combinations as CT1 and CT2. RESULts: The median overall survival (OS) of patients who received and CT2 was 10.2 and 5.5 months, respectively. Good performance status (PS), a serum albumin level >3.5 g/dl and metastasis to only 1 organ were independent prognostic factors that affected the OS of the patients who received CT2. Patients who had only 1 metastastic organ, a good PS and a serum albumin level >3.5 g/dl at the beginning of CT2 demonstrated prolonged survival compared to patients who did not exhibit these 3 factors (9.5 vs. 4.3 months, p < 0.005).
Conclusions:
CT2 should be considered for patients with advanced BTC, especially for those who have only 1 metastatic organ and remain in generally good medical condition after the failure of CT1.
