title: Long-term survival of transmural advanced gastric carcinoma following curative resection: multivariate analysis of prognostic factors.
abstract: Patients with transmural (T2N0-T3N2) advanced gastric carcinoma comprise the largest group with uncertain outcome. These patients must be stratified according to the prognostic variables so the high risk group can be precisely identified. A total of 152 patients with transmural advanced gastric carcinomas were uniformly treated with a curative intent between 1979 and 1989 with at least a 7-year follow-up. Results and prognostic factors of long-term survival were analyzed by univariate and multivariate analyses. Seventy-five (49%) patients with advanced gastric carcinoma survived more than 7 years, which indicates the curative nature of surgery for gastric carcinoma. Seventeen variables were evaluated by univariate analysis. In the multivariate analysis, patient's age [>70 years, relative risk (RR) 2.4)], intraoperative blood loss (>500 ml, RR 1.7), blood vessel invasion (RR 2.3), ratio of invaded dissected lymph nodes (>0.2, RR 3.0), and tumors penetrating the serosa (RR 3.9) were the independent prognostic variables. The results of this study indicate that extensive lymphadenectomy and minimal intraoperative blood loss might be helpful for improving patient survival following a curative resection. Patients with vessel invasion, serosal involvement, and those >70 years of age should be considered at high risk and require appropriate adjuvant therapy to prolong survival.
