Overall survival of PGC patients who underwent R0 gastrectomy was much better than patients who underwent conservative treatment, repair or palliative partial gastrectomy. A The Kaplan–Meier curve of all 74 PGC patients, and the median survival for the whole cohort was 16 months (95% CI: 13–21 months). B Compared with patients who underwent conservative treatment, repair or palliative partial gastrectomy gastrectomy (median survival time was 4 months, 95% CI: 2–10 months), patients who underwent R0 gastrectomy had a significantly better OS (median survival time was 21 months, 95% CI: 18–39 months, P < 0.001)
