In this study, we present the results of surgery and chemotherapy and the impact of various prognostic factors on survival in patients with gastric carcinoma with a follow-up of 6 years. All of the 328 cases were adenocarcinoma histologically and had a median age of 55 years. Median survival was 11 months, and the 5-year survival rate was 18%. Nonmetastatic cases were associated with improved survival as compared with the cases with metastatic disease (p < 0.001). Patients with gastrectomy had improved survival (p < 0.001). Subtotal gastrectomized patients had better survival rates in comparison to the total gastrectomized patients (p = 0.03). Addition of splenectomy to total gastrectomy and adjuvant chemotherapy did not influence survival rates (p > 0.05). In metastatic patients, we determined beneficial effects of gastrectomy and chemotherapy on survival. The benefit was most predominant in chemoresponsive patients (p < 0.001). Higher serum CA 19.9 levels in patients without metastases, higher serum lactate dehydrogenase and carcinoembryonic antigen levels in patients with metastases, and lower serum albumin levels in both stages were determined as significant predictors of poor survival. On multivariate analysis, only higher serum CA 19.9 level was the independent unfavorable prognostic factor of survival time in nonmetastatic patients (p = 0.008). In metastatic disease, older age (p = 0.03) and male gender (p = 0.05) were associated with poorer survival. In conclusion, gastric cancer is a great health problem, especially in developing countries, and we need more optimal approaches and treatment modalities for gastric cancer.
