Abstract

AIM: To describe survival trends in patients in Northeast China diagnosed as gastric cancer.

METHODS: A review of all inpatient and outpatient records of gastric cancer patients was conducted in the First Affiliated Hospital of China Medical University. All the gastric cancer patients who satisfied the inclusion criteria from January 1, 1980 through December 31, 2003 were included in the study. The main outcomes were based on median survival and 3-year and 5-year survival rates, by decade of diagnosis.

RESULTS: From 1980 through 2003, the median survival for patients with gastric cancer (n = 1604) increased from 33 mo to 49 mo. The decade of diagnosis was not significantly associated with patient survival for gastric cancer (P = 0.084 for overall survival, and P = 0.150 for 5-year survival); however, the survival rate of the 2000s was remarkably higher than that of the 1980s (P = 0.019 for overall survival, and P = 0.027 for 5-year survival).

CONCLUSION: There was no significant difference of survival among each period; however, the survival rate of the 2000s was remarkably higher than that of the 1980s.
