AIM: To investigate remnant gastric cancer(RGC) at various times after gastrectomy, and lay a foundation for the management of RGC.METHODS: Sixty-five patients with RGC > 2 years and< 10 years after gastrectomy(RGC Ⅰ) and forty-nine with RGC > 10 years after gastrectomy(RGC Ⅱ) who underwent curative surgery were enrolled in the study.The clinicopathologic factors, surgical outcomes, and prognosis were compared between RGC Ⅰ and RGC Ⅱ.RESULTS: There was no significant difference in surgical outcomes between RGC Ⅰ and RGC Ⅱ. For patients reconstructed with Billroth Ⅱ, significantly more patients were RGC Ⅱ compared with RGC(71.9%vs 21.2%, P < 0.001), and more RGC Ⅱ patients had anastomotic site locations compared to RGC Ⅰ(31.0%vs 56.3%, P = 0.038). The five-year survival rates for the patients with RGC Ⅰ and RGC Ⅱ were 37.6%and 47.9%, respectively, but no significant difference was observed. Borrmann type and tumor stage were confirmed to be independent prognostic factors in both groups.CONCLUSION: RGC Ⅱ is located on the anastomotic site in higher frequency and more cases develop after Billroth Ⅱ reconstruction than RGC Ⅰ.
