Twenty-six cases of advanced ampullary adenocarcinoma treated with systemic chemotherapy.

Abstract:

OBJECTIVE: Ampullary adenocarcinoma is a rare disease entity and little information regarding these tumors is available. The aim of the present study was to clarify the treatment outcome of systemic chemotherapy in patients with advanced ampullary adenocarcinoma.
METHODS: This study consisted of a retrospective review of data obtained from patients diagnosed as having advanced ampullary adenocarcinoma who received non-surgical treatment at a single institution between 1997 and 2010.
RESULTS: We identified 26 patients (15 men, 11 women; median age, 62.0 years) who received treatment for advanced ampullary adenocarcinoma. Twelve patients had Stage IV disease and 14 had recurrences. The chemotherapy regimens consisted of 5-fluorouracil-based regimens (5-fluorouracil + cisplatin, n = 3; tegafur-uracil + doxorubicin, n = 5 and tegafur, gimeracil and oteracil potassium, n = 3) and gemcitabine-based regimens (gemcitabine, n = 10 and gemcitabine + cisplatin, n = 5). The overall response rate was 7.7%. The median progression-free survival period was 3.2 months (2.5 months in the 5-fluorouracil group vs. 3.5 months in the gemcitabine group), and the median overall survival time was 9.1 months (8.0 months in the 5-fluorouracil group vs. 12.3 months in the gemcitabine group). The median overall survival was significantly longer in stage IV disease than in recurrent disease. The histological phenotype was determined in 10 of the 26 patients. Eight patients had intestinal-type adenocarcinomas and remaining two patients had pancreatobiliary-type adenocarcinomas.
CONCLUSIONS: The treatment outcome of patients with advanced ampullary adenocarcinoma was poor. Further development of novel treatments is necessary to improve the prognosis.
