Preoperative Geriatric Nutritional Risk Index is an independent prognostic factor for postoperative survival after Gallbladder carcinoma radical surgery

Abstract Background Surgical results of gallbladder cancer (CBG) are currently inadequate. The Geriatric Nutritional Risk Index (GNRI) can effectively assess nutritional status. The present study attempted to delve into investigating whether preoperative GNRI can act as a predicting factor for CBG. Methods 202 consecutive GBC patients treated from 2010 to 2017 were taken retrospectively. By conducting univariate and multivariate Cox regression analyses on overall survival (OS) and recurrence-free survival (RFS), their preoperative GNRI was studied. Results Of the 202 patients, 103 (51.0%) had GNRI<100. The patients with low GNRI before surgery had the median OS of 26 months, less than that of patients having received high GNRI before surgery (39 months, P<0.001). GNRI displayed associations with less survival times in univariate (HR, 3.656; 95%CI, 2.308-5.790; P<0.001). As indicated from the results of multivariate analysis, patients exhibiting low GNRI showed a lower OS (HR, 2.386; 95%CI, 1.170-4.868; P=0.017) and RFS (HR, 7.610; 95%CI, 3.181-18.207; P<0.001) than those exhibiting high GNRI. Conclusions GNRI is an independent indicator of poor prognosis in GBC patients after GBC radical surgery.
