Less-invasive surgery for gastric cancer prolongs survival in patients over 80 years of age.
This study was undertaken to determine the most appropriate form of surgery for elderly patients with gastric cancer in relation to postoperative complications and long-term survival. A total of 72 consecutive patients over 80 years of age who underwent partial or total gastrectomy were evaluated using an E-PASS scoring system. This system is comprised of a preoperative risk score (PRS), a surgical stress score (SSS), and a comprehensive risk score (CRS) determined by both the PRS and SSS. Patients with a CRS > or = 0.5 had significantly higher rates of morbidity and mortality at 45.0% and 20.0%, respectively, than those with CRS < or = 0.5, at 17.0% and 2.1%, respectively. A Cox regression analysis of long-term survival, including death from other causes, identified five significant prognostic factors, namely: stage, curability, SSS, CRS, and allogeneic blood transfusion. Among the patients without any apparent residual cancer, a significantly better survival was seen in those who underwent less invasive surgery (SSS < 0.25), those with a CRS < or = 0.5, and those who had not been given a blood transfusion. These results suggest that less invasive surgery not requiring a blood transfusion is advisable for patients over 80 years of age with gastric cancer. Furthermore, gastrectomy with a CRS > or = 0.5 may have a poor therapeutic effect on both early and long-term outcome.
