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.
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 curative-intent surgical resection of confirmed adenocarcinoma originating from the biliary tract.
The median time to recurrence after surgery was 16.1 months (range, 4.5-77.8 months). Median follow-up 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.
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.
