# Exploring the Link Between Nutritional and Functional Status and Short-Term Postoperative Outcomes in Patients Undergoing Pancreatic Cancer Surgery

## TL;DR

This study shows that poor nutrition and physical function before surgery increase risks of complications and longer hospital stays in pancreatic cancer patients.

## Contribution

The study identifies specific preoperative nutritional and functional risk factors linked to postoperative outcomes in pancreatic cancer surgery.

## Key findings

- Severe malnutrition and low GNRI were strongly associated with higher complication rates.
- Lower hemoglobin and hematocrit levels were linked to major complications and mortality.
- Weaker handgrip strength and slower gait speed correlated with longer hospital stays.

## Abstract

Background: Patients with pancreatic cancer are at increased risk of malnutrition and functional decline. This study aimed to identify preoperative nutritional and functional risk factors associated with postoperative complications. Methods: Adult patients with pancreatic cancer admitted to two university surgical departments in Athens, Greece, were included. Preoperative laboratory values, nutritional status, and functional status were assessed. Results: Among 96 patients included in this study, postoperative complications occurred in 69 (71.9%). Complication rates were significantly higher in patients with severe malnutrition (87.9% vs. 62.7%, p = 0.015), low Geriatric Nutritional Risk Index (GNRI) (90.5% vs. 66.2%, p = 0.023), low handgrip strength (91.7% vs. 61.5%, p = 0.037), and low gait speed (90.5% vs. 63.6%, p = 0.027). Major complications were linked to lower hemoglobin (Hb) (11.5 ± 1.9 vs. 12.8 ± 1.7 g/dL, p = 0.001), lower hematocrit (HCT) (34.7 ± 5.4% vs. 38.4 ± 4.7%, p = 0.001), and severe malnutrition (42.4% vs. 23.7%, p = 0.05). Lower Hb, lower HCT, malnutrition, and greater waist circumference were associated with postoperative mortality. Longer hospital stays were correlated with weaker handgrip strength and slower gait speed. Conclusion: Preoperative malnutrition and impaired functional status are significant predictors of adverse postoperative outcomes in pancreatic cancer surgery.
