    Abstract:
    Although the therapeutic results of gastric cancer have markedly improved, it still remains the most common of cancer deaths in Korea. Annually more than 700, and all together 11,946, gastric cancer patients were surgically treated from 1970 to 1998 at Seoul National University Hospital. Stage III gastric cancer is already a systemic disease, Radical surgery alone cannot cure the patient, and about 35% recurred within 2-3 years. To improve the prognosis of advanced gastric cancer, systemic treatment such as immunotherapy and chemotherapy is required in the early postoperative period to kill the micrometastatic or remaining cancer cells after curative resection. We evaluated the survival rate and prognostic factors for 9,262 consecutive patients from 1981 to 1996. The clinicopathologic variables used for evaluating prognostic values were classified into patient, -tumor- and treatment-related factors. The prognostic significance of treatment modality was evaluated in stage III gastric cancer. The five-year survival rates were 55.9% for overall patients and 64.8% for patients who received curative resection. Radical lymph node dissection was found to produce survival gains in patients with stage II and IIIa. For postoperative adjuvant therapy, immunochemotherapy was most effective in patients with stage III. In multivariate analysis, curability of operation, depth of invasion, and ratio of involved-to-resected lymph nodes were the significant prognostic factors. Consequently, early detection and real curative resection with radical lymph node dissection, followed by immunochemotherapy (particularly in patients with stage III gastric cancer) should be recommended as a standard treatment principle for patients with gastric cancer.
