  1. * The Mann Whitney test was applied.
  2. † The stage was determined by pathological (p) examination. T1: Tumor invading submucosa, T2: Tumor invading muscularis propria, T3: Tumor penetrating muscularis propria and invading subserosa, and T4: Tumor invading other organs or structures or perforating visceral peritoneum.
