Purpose: The purpose of this study was to investigate the clinical outcomes and prognostic factors of concurrent chemoradiotherapy (CCRT) for locally recurrent biliary tract cancer (BTC) after curative surgical resection. Methods: We performed a retrospective cohort study of patients with locally recurrent BTC treated with CCRT between October 2004 and December 2013. The study included and analyzed 42 patients with a history of curativeintent surgical resection of confirmed adenocarcinoma originating from the biliary tract. Results: The median time to recurrence after surgery was 16.1 months (range, 4.5-77.8 months). Median followup after CCRT was 26.9 months (range, 5.2-81.9) with no grade 3 or higher gastrointestinal toxicities. Analysis of the first site of failure showed local progression (LP) developed in 20 patients (47.6%); among these, 16 (38.1%) had isolated LP. The median values were 15.8 months (range, 1.7-81.7) for LP-free survival (LPFS), 10.6 months (range, 1.7 -81.7) for progression-free survival (PFS) and 41.2 months (range, 5.2-81.9) for overall survival (OS). Multivariate analysis showed that the level of pre-CCRT carbohydrate antigen (CA) 19-9 and the chemotherapy regimen were significant prognostic factors for LPFS and PFS; pT stage was the only significant prognostic factor for OS. Conclusions: CCRT for locally recurrent BTC showed promising outcomes as a salvage modality, but LP was still frequent. The pre-CCRT CA 19-9 level and the chemotherapy regimen were prognostic factors for LPFS and PFS.
