  • OBJECTIVES To determine in a prospective randomized clinical trial, the effect of extended lymph node dissection (R3 gastrectomy) versus conventional surgery (R0/1 gastrectomy) on tumor recurrence and survival in Chinese patients with advanced cancer of the stomach (adenocarcinoma invasion beyond submucosa).
  • STATISTICAL CONSIDERATIONS The major end points are disease free survival and survival. The log-rank test will be used as analytic method on disease-free survival and overall durvival. The follow-up time after treatment is five years.

Previous experience provides an estimation of a 20% 5-year survival rate with conventional surgery for gastric cancer. Assuming that this new treatment (radical surgery) may increase the 5-year survival rate to 40%, we estimate that 118 evaluable patients are required to detected a significance at a of 0.05 level and power of 0.8 using a one tailed test.

We expect to enter 50 patients per year and finish accrual of patient within 2.5 years.
