[Significance and Treatment Strategy of Glasgow Prognostic Score in High Risk Stage Ⅱ Colorectal Cancer].

In this study, we investigated the usefulness of Glasgow prognostic score(GPS)as a prognostic factor for Stage Ⅱ colorectal cancer, and the treatment strategy by individualizing adjuvant chemotherapy. We enrolled 86 patients with Stage Ⅱ primary colorectal cancer who underwent curative resection. This study examines the prognostic significance of clinicopathological factors and GPS, NLR, LMR, PLR. Multivariate analyses was performed to evaluate the factors affecting recurrence free survival. The 5-year OS was 92.5%, and the RFS was 86% in Stage Ⅱ colorectal cancer. The recurrence rate was 12.8%. In multivariate analysis, GPS(HR: 13.66, p=0.005)was extracted as an independent poor prognosis factor. In comparison of survival rates, RFS of GPS 0, 1 was 95.2% and that of GPS 2 43.8%, and GPS 2 had a significantly poor prognosis(p< 0.01). GPS 2 is an independent high risk factor for recurrence of Stage Ⅱ colorectal cancer. In order to improve the prognosis of Stage Ⅱ colorectal cancer, individualized adjuvant chemotherapy is important.
