Postoperative Chemotherapy in Resected Gastric Cancer: Results of a Single Center Experience

AbstractGastric cancer remains a major health problem despite its decline in incidence in Western countries. Although radical surgery represents the primary curative option for gastric cancer patients, most of them relapse and die due to their disease despite an R0 resection. At present the routine use of postoperative adjuvant therapy to reduce disease recurrence is still considered an investigational approach. Out of a total of 275 patients (stage IB through IV M0 AJCC/UICC) who underwent surgery for gastric cancer at our Surgery Unit between 1993 and 2001, 156 were eligible for adjuvant chemotherapy, of whom only 52 accepted to undergo this treatment. This group of patients was retrospectively compared with a control group (1:2) and overall survival was assessed using hazard ratio and Kaplan-Meier estimates. Five-year survival was 40% in the chemotherapy group and 37.8% in the group which underwent surgery alone. Indeed, chemotherapy did not reduce the risk of death (HR 0.87, 95% CI = 0.57-1.34, p=0.54...
