Abstract

Purpose: The role of postoperative therapy in extrahepatic cholangiocarcinoma (EHCC) or gallbladder carcinoma (GBCA) is unknown. S0809 was designed to estimate 2-year survival (overall and after R0 or R1 resection), pattern of relapse, and toxicity in patients treated with this adjuvant regimen. Patients and Methods: Eligibility criteria included diagnosis of EHCC or GBCA after radical resection, stage pT2-4 or N+ or positive resection margins, M0, and performance status 0 to 1. Patients received four cycles of gemcitabine (1,000 mg/m 2 intravenously on days 1 and 8) and capecitabine (1,500 mg/m 2 per day on days 1 to 14) every 21 days followed by concurrent capecitabine (1,330 mg/m 2 per day) and radiotherapy (45 Gy to regional lymphatics; 54 to 59.4 Gy to tumor bed). With 80 evaluable patients, results would be promising if 2-year survival 95% CI were > 45% and R0 and R1 survival estimates were ≥ 65% and 45%, respectively. Results: A total of 79 eligible patients (R0, n = 54; R1, n = 25; EHCC, 68%; GBCA, 32%) were treated (86% completed). For all patients, 2-year survival was 65% (95% CI, 53% to 74%); it was 67% and 60% in R0 and R1 patients, respectively. Median overall survival was 35 months (R0, 34 months; R1, 35 months). Local, distant, and combined relapse occurred in 14, 24, and nine patients. Grade 3 and 4 adverse effects were observed in 52% and 11% of patients, respectively. The most common grade 3 to 4 adverse effects were neutropenia (44%), hand-foot syndrome (11%), diarrhea (8%), lymphopenia (8%), and leukopenia (6%). There was one death resulting from GI hemorrhage. Conclusion: This combination was well tolerated, has promising efficacy, and provides clinicians with a well-supported regimen. Our trial establishes the feasibility of conducting national adjuvant trials in EHCC and GBCA and provides baseline data for planning future phase III trials.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
