Abstract: Objective The aim of this study was to explore the predictive value of the systemic inflammatory immune nutrition score(SIINS)for the prognosis of immunotherapy for advanced gastric cancer. Methods A retrospective analysis was conducted on the clinical data of 202 patients with advanced gastric cancer who received treatment with programmed death-1(PD-1)inhibitors at the Harbin Medical University Cancer Hospital from October 2018 to July 2022.The LASSO regression analysis was used to screen prognostic indicators,construct SIINS indicator,determine the optimal cutoff value for predicting prognosis using subject operating characteristic curves,and divide patients into the high SIINS and low SIINS groups.Independent prognostic factors for overall survival(OS)were determined using univariate and multivariate Cox regression analyses. Results Four indicators,including lymphocyte count,lactate dehydrogenase,and neutrophil lymphocytes,were selected to construct the SIINS index.The prognosis of patients in the high SIINS group was significantly lower than that in the low SIINS group(P<0.05).The results of the multifactorial Cox regression analysis showed that the Eastern Cooperative Oncology Group(ECOG)score,Geriatric Nutritional Risk Index(GNRI),SIINS,treatment regimen,and number of treatment lines(P<0.05)could serve as the independent predictive prognosis of immunotherapy for advanced gastric cancer. Conclusion SIINS can predict the prognosis of patients with advanced gastric cancer treated with PD-1 inhibitors.
