Abstract

Background: Gallbladder cancer (GBC) is the second leading cause of cancer death in women in Chile. Even after curative surgery, prognosis is grim. To evaluate acute and late toxicity and efficacy of adjuvant chemoradiation (CRT) after curatively resected GBC. Materials and Methods: We retrospectively analyzed the cohort of patients diagnosed between January 1999 and December 2009, treated with adjuvant CRT at our institution. Treatment protocol considered external beam radiation (RT) (45-54 Gy) to tumor bed and regional lymph nodes with or without concurrent 5-fluorouracil (5-FU) (500 mg/m 2/day by 120-hours continuous infusion on days 1-5 and 29-33). Data was obtained from medical records, mortality from death certificates. Survival was estimated by Kaplan-Meier curves. Results: 46 patients with curatively resected GBC received adjuvant CRT. Median age was 57 years (range 33-76); 39 patients were female. After diagnosis, a second surgery was performed in 42 patients. Cholecystectomy with hepatic segmentectomy and lymphadenectomy was the curative surgery in 41 patients. All patients received RT with a planned dose of 45 Gy in 25 fractions, 11 patients received a boost to the tumor bed up to 54 Gy and 34 patients had concurrent 5-FU. Therapy was well tolerated. Five patients experienced grade 3 toxicities. No grade 4 or 5 toxicity was observed. No grade >2 late toxicity was observed. Three-and 5-year overall survival (OS) were 57% and 51%, respectively. Conclusions: Adjuvant chemoradiation is well tolerated and might impact favorably on survival in patients with curatively resected GBC.
