We conducted a retrospective study to investigate the impact of metabolic syndrome (MetS), its individual components, and the number of metabolic risk factors on the prognosis of pancreatic cancer (PC) following pancreatectomy.
MetS was defined as meeting any three of the following criteria: (1) waist circumference ≥85 cm in men or ≥80 cm in women; (2) triglycerides ≥150 mg/dL or receiving drug treatment for elevated triglycerides; (3) high-density lipoprotein cholesterol <40 mg/dL in men or <50 mg/dL in women or receiving drug treatment for reduced HDL-C; (4) systolic blood pressure ≥130 mmHg and/or diastolic blood pressure ≥85 mmHg or receiving drug treatment for hypertension; and (5) fasting glucose, (FG) ≥100 mg/dL or receiving drug treatment for elevated glucose. The hazard ratio (HR) and 95% confidence interval (CI) were calculated by the Cox regression model.
Six hundred and seven patients who underwent radical resection for PC were enrolled in this study. Among them, 352 patients presented with preoperative MetS. MetS was associated with shorter overall survival (OS) but not with shorter disease-free survival (DFS). The adjusted HR (95% CI) for the poor OS in patients with 3, 4, and 5 metabolic risk components (vs. ≤ 2) were 1.32 (1.03-1.84), 1.64 (1.18-2.29), and 1.96 (1.27-3.04), respectively (p < 0.05). Elevated FG emerged as a significant predictor for poor OS and DFS.
This study highlights that preoperative MetS serves as a significant predictor for OS in patients with PC, with its predictive value escalating as the number of metabolic risk components increases.
