Survival of young patients after gastrectomy for gastric cancer.

It has been suggested that gastric cancer has a worse prognosis in young patients, but the data are controversial. The aim of this study was to compare the 5-year survivals after gastrectomy for gastric cancer in two groups of patients (those < or = 45 years of age and those (> 45 years) and to determine some of the prognostic factors. The 5-year survival was significantly better for patients < or = 45 years of age. Survival was also better for young patients with a curative resection and also for those with lymph node metastases. However, survival was not significantly different for the two groups when the resection was not curative and when the lymph nodes were not involved. Survival was no different for the two groups when compared at each stage, although a multivariate analysis showed that age > 45 years, moderate or poor degree of differentiation of the tumor, advanced tumors, the presence of lymph node involvement, and a noncurative resection were independent negative prognostic factors. Long-term survival after gastrectomy for gastric cancer depends on the stage of the disease; the age of the patient is not a decisive factor.
