Abstract
Objectives
This study investigated the use of standardized phase angle (SPA), determined by bioelectrical impedance analysis (BIA), as a nutrition status tool and prognostic factor for complications associated with pancreaticoduodenectomy (PD) in pancreatic cancer patients.
Methods
A cross-sectional study was conducted with 49 participants. All participants were assessed for nutritional risk and nutritional status using Nutritional Risk Screening 2002 (NRS-2002), Subjective Global Assessment (SGA) tools, Global Leadership Initiative on Malnutrition (GLIM) tool and BIA. The Clavien-Dindo classification method for surgical complications was used to identify and classify postoperative complications. Independent-samples T-tests, chi-square tests and Spearman correlation analyses were used to evaluate the association between SPA, nutrition and postoperative complications.
Results
A total of 49 patients were enrolled, and 20 patients (40%) had postoperative complications. The SPA value for the nourished group was significantly higher than the SPA value for the malnourished group (P = 0.021, 0.019, 0.023). Patients who were below the SPA cut-off values (−1.015, −1.065, and −0.69) were more likely to have postoperative complications (P = 0.009), whereas NRS-2002, SGA, and GLIM scores were not associated with postoperative complications. The SPA value of the group with complications was significantly lower than that of the group without complications (P = 0.004). The SPA threshold value for predicting postoperative complications in pancreatic cancer was −1.095 (AUC 0.737; 95% CI, 0.59, 0.88; P = 0.005).
Conclusions
The SPA is a prognostic indicator of postoperative complications in pancreatic cancer patients undergoing PD and is an effective tool for assessing nutritional status in pancreatic cancer patients.
