The PGC patients who underwent one-stage R0 gastrectomy had poorer quality lymphadenectomy and worse overall survival compared with propensity score-matched regular GC patients. A Compared with propensity score-matched 29 regular GC patients, 29 PGC patients who underwent one-stage R0 gastrectomy harvested significantly fewer total lymph nodes (P < 0.001) and fewer positive lymph nodes, but not significantly (P = 0.054). B Compared with 29 PGC patients who underwent one-stage R0 gastrectomy, 29 propensity score-matched patients with regular GC had a significantly better OS (P = 0.024). C Compared to 15 propensity score-matched regular GC patients, 15 PGC patients who underwent two-stage R0 gastrectomy had a similar number of total and positive lymph nodes harvested (P = 0.506, P = 0.787). D Compared to 15 propensity score-matched regular GC patients, 15 PGC who underwent two-stage R0 gastrectomy had a similar OS (P = 0.096)
