FP2.2 - Does preoperative nutritional assessment correlate with postoperative outcomes of patients undergoing surgery due to colorectal cancer? A bicenter prospective observational study
Year: 2024
Type: article
Study design: Observational Study
Abstract: Aims Preoperative nutritional status has been investigated as a risk factor for postoperative complications in patients undergoing surgery due to colorectal surgery. The aim of the present study was to investigate the predictive role of preoperative nutritional assessment in terms of morbidity and mortality in such patients. Methods Patients undergoing surgery due to colorectal cancer from March 2022 until March 2023 at two university surgical departments were included in the present study. Patients’ demographics and postoperative parameters, such as complications’ severity according to Clavien-Dindo classification and mortality, along with malignancy stage were reported. Preoperative nutritional assessment was conducted according to the Patient-Generated Subjective Global Assessment (PG-SGA) tool and the Geriatric Nutritional Risk Index (GNRI) tool. The present study was registered in ClinicalTrials.gov (NCT05795374). Results The present study included 159 patients with a mean age of 69 ± 12 years old. Severe malnutrition according to the PG-SGA tool was associated with advanced disease stage (66% vs 59%, p=0.006). In addition, the high risk of malnutrition according to the GNRI tool was correlated to major (Clavien-Dindo≥3) postoperative complications (19% vs 15%, p=0.026) and increased 30-day mortality (34% vs 9%, p=0.026). Conclusions Postoperative morbidity and mortality of patients undergoing surgery due to colorectal cancer seem to be associated with preoperative nutritional stratification, especially with the high malnutrition risk.
