Clinico-pathological features and prognostic analysis of gastric cancer patients in different age groups.

BACKGROUND/AIMS: The prognostic value of age on patients with gastric cancer is not well defined. The aim of this retrospective study is to analyze the impact of age on survival in patients with gastric cancer.

METHODOLOGY

A total of 1800 patients with gastric carcinoma, who had undergone gastrectomy between 1997-2007 years were included. They were divided into six different age groups (21-30, 31-40, 41-50, 51- 60, 61-70 and 71-80 years). We reviewed patient's clinico-pathological characteristics and the prognosis with special reference to their ages.

RESULTS

Among the six age groups, the younger patients have more female-dominated patients and poorly differentiated carcinoma, whereas the older patients have a higher incidence of large tumors (≥5 cm) and more patients with stage T3. Moreover, there were more liver metastases in the older age groups. Univariate analysis showed that there were significant differences in 5-year survival rates among the six age groups. Multivariate analysis confirmed age, tumor size, pT stage, pN stage and curability were independent prognostic factors.

CONCLUSION

There are several distinctive properties related to age of patients with gastric cancer, the older patients have more aggressive features and poorer prognosis than the younger patients.
