Preoperative Nutritional Evaluation of Elderly Patients with Prostate Cancer Undergoing Laparoscopic Radical Prostatectomy


 Objective

The purpose of this study is to evaluate the association and predictive value of geriatric nutritional risk index (GNRI) in elderly patients with prostate cancer(PCa) undergoing laparoscopic radical prostatectomy (LRP).
Methods

the clinical data of 72 elderly patients (aged ≥ 65 y) with PCa undergoing LRP in the Department of Urology, Affiliated Hospital of North Sichuan Medical College from January 2018 to December 2020 were retrospectively analyzed. The basic information, laboratory examination indexes, operation conditions, postoperative complications and postoperative recovery indexes of patients were included. Clavien-Dindo Classification System (CDCS) was used to assess the postoperative complications. T-test was used to analyze the grouping variables. ROC curve was drawn to study the predictive value of GNRI for postoperative complications.
Results

The body weight, BMI, preoperative HGB, ALB values of malnutrition group (MNg) and normal nutrition group (NNg) were significantly positively correlated (P༜0.01); the incidence and severity of postoperative complications of MNg were significantly higher than those of NNg (P༜0.05). The average hospitalization costs of MNg was higher, the duration of postanesthesia care unit (PACU), duration of antibiotic use was longer and the duration of indwelling drainage tube were longer than NNg (P༜0.05). The volume of indwelling drainage tube were more than NNg (P༜0.05).
Conclusion

GNRI is an effective and reliable tool to evaluate preoperative nutritional status of prostate cancer, which is closely related to postoperative recovery and complications,and has predictive value.
