摘要

Background

Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis, with a 5-year survival rate of 13%. Surgical resection followed by adjuvant chemotherapy remains the only curative approach. However, complications such as postoperative pancreatic fistula (POPF) and postpancreatectomy hemorrhage (PPH) often delay or prevent further treatment. Reliable preoperative biomarkers for predicting these complications are lacking. This study investigated soluble CD40 (sCD40) as a potential predictive marker for pancreas-specific complications after pancreatoduodenectomy (PD) in patients with PDAC.

Methods

Preoperative serum samples from 185 patients with PDAC undergoing pylorus-preserving pancreatoduodenectomy or a Whipple procedure were analyzed using enzyme-linked immunosorbent assay to quantify sCD40 levels. Clinical and postoperative data were systematically collected and classified.

Results

Of the 185 patients, 151 underwent pylorus-preserving PD and 34 a Whipple procedure. Clinically relevant POPF occurred in 9.7% and PPH in 7.6% of patients. Preoperative sCD40 levels were significantly lower in patients who developed POPF or PPH (P = 0.025 and P = 0.008). The association remained significant in multivariable analysis. Receiver operating characteristic analysis demonstrated an area under the curve of 0.660 for sCD40. Adding leukocytes and body mass index improved predictive performance (area under the curve 0.705 for POPF and 0.752 for PPH).

Conclusion

Reduced preoperative sCD40 serum levels are associated with a higher risk of POPF and PPH after PD. Combining sCD40 with leukocytes and BMI may enhance preoperative risk assessment in patients with PDAC.
