Clinicopathological Characteristics and Prognoses of Elderly Gastric Cancer Patients after R0 Resection: A Multicenter Study in China.
The number of elderly gastric cancer (GC) patients has been rapidly increasing worldwide, but inadequate understanding regarding elderly GC patients has led to the paucity of appropriate treatment decisions. Our study evaluates clinicopathological characteristics and prognoses of elderly GC patients after R0 resection. Overall, 1877 consecutive GC patients who underwent R0 gastrectomy at four centers were enrolled. We divided patients into three groups according to age: young, middle, and elderly. We then analyzed clinicopathological characteristics and prognoses. Compared to the middle-aged group, the elderly group had a higher male-to-female ratio and number of patients with cardiac GC, trend of more advanced pathological stage, lower ratio of poor to moderate tumor grade, and fewer patients who received adjuvant chemotherapy or chemoradiotherapy. Moreover, 5 yr disease-free survival and overall survival rates of elderly patients were significantly less than those of middle-aged patients. A Cox analysis of middle-aged and elderly patients revealed that age and adjuvant chemotherapy were independent prognostic factors. Adjuvant chemotherapy improved long-term survival of elderly patients with stage III cancer. Elderly GC patients who underwent R0 resection had unique characteristics and poor long-term survival. We found that subjects should be stratified into the three aforementioned age groups when analyzing survival rates of GC patients. In addition, reasonable adjuvant treatment is recommended for elderly patients.
