Clinicopathologic characteristics of serosa-positive gastric carcinoma in elderly patients

PURPOSE: The relationship between the prognosis and the age of patients with gastric carcinoma is controversial. This study examined the clinicopathologic features of elderly gastric carcinoma patients with serosal invasion. METHODS: We reviewed the hospital records of 136 elderly gastric carcinoma patients with serosal invasion retrospectively to compare the clinicopathologic findings in the elderly (aged > 70 years) and young (aged < 36 years). RESULTS: The 5-year survival rates of elderly and young patients with curative resection did not differ statistically (33.9% vs. 43.3%; P = 0.318). Multivariate analysis showed that two factors were independent, statistically significant parameters associated with survival: histologic type (risk ratio, 1.805; 95% confidence interval [CI], 1.041 to 3.132; P < 0.05) and operative curability (risk ratio, 2.506; 95% CI, 1.371 to 4.581; P < 0.01). CONCLUSION: This study demonstrated that elderly gastric carcinoma patients with serosal invasion do not have a worse prognosis than young patients. The important prognostic factor was whether the patients underwent curative resection.
