Short- and Long-term outcomes of robotic gastrectomy for gastric cancer: multi-institutional retrospective study - Robotic gastrectomy

Of the 1,127 patients in the previous study, 326 and 752 patients in the RG and LG groups, respectively, completed the study. In the weighted population, 3yOS was 96.3% and 89.6% in the RG and LG groups, respectively (hazard ratio [HR], 0.34 [0.15, 0.76]; p = 0.009), whereas there was no difference in three-year recurrence-free survival rate (3yRFS) between the two groups (HR, 0.58 [0.32, 1.05]; p = 0.073). Sub-analyses showed that RG improved 3yOS and 3yRFS in patients with pStage IA disease.
