ABSTRACT

BACKGROUND:

Ampullary cancer accounts for only 0.2% of gastrointestinal cancers. The objective of this study was to investigate the incidence, demographics, tumor characteristics, treatment, and survival of patients with ampullary tumors.

METHODS:

Data on ampullary cancer between 2004 and 2013 was extracted from the Surveillance, Epidemiology and End Results (SEER) Registry. The clinical epidemiology of these tumors was analyzed using SEER*Stat.

RESULTS:

A total of 6803 patients with ampullary cancer were identified. Median age at diagnosis was 71±13 years. The overall age-adjusted incidence of ampullary cancer was 0.59 per 100,000 per year. A higher incidence of ampullary cancer was observed in males compared to females (0.74 vs. 0.48 per 100,000 per year). Most tumors were moderately differentiated (39.5%). The most common stage at presentation was Stage I (21%), followed by Stage II (20%). The majority (63%) of these tumors were surgically resected while 20% of patients received radiotherapy. One and 5-year cause-specific survival for ampullary cancer was 71.7% and 38.8% respectively, with a median survival of 31 months. On Cox regression analysis, black race, increasing cancer stage and grade, N1 stage, and non-surgical treatment were associated with poorer prognosis. Those who were not treated with surgical intervention were at 4.5 times increased risk for death (hazard ratio 4.5, 95% CI 3.93-5.09, P=0.000).

CONCLUSIONS:

The annual incidence of ampullary cancer has been fairly constant, though males are more likely to be affected. While its incidence increases with age, patients who are treated by surgical intervention have significantly better outcomes. Additionally, through the use of endoscopic techniques, ampullary cancer can be detected and treated much earlier.
