Abstract:

Objective

To explore and compare the clinical application of biliary stent combined with 125I seeds implantation and palliative surgery (PS) in patients with advanced extrahepatic cholangiocarcinoma (EHCC).

Methods

136 advanced EHCC patients, who were admitted into Department of Hepatobiliary Surgery, the First Affiliated Hospital of Bengbu Medical College and received medical treatment between January 2014 and December 2019, were analyzed retrospectively. According to the treatment method, the patients were divided into two groups: combination group (received biliary stent combined with 125I seeds implantation, 91 cases) and PS group (underwent open choledochojejunostomy and cholecystectomy, 45 cases). The levels of serum bilirubin, aminotransferase and albumin (ALB) were observed at 1, 3 and 6 months postoperatively in the two groups. The length of stay, hospital costs, and postoperative overall complications were compared between the two groups. Kaplan-Meier curves were used to analyze the differences in overall survival (OS).

Results

The serum levels of bilirubin, transaminase, and ALB at 1, 3, and 6 months postoperatively were improved in both groups, compared with preoperative values. There was no statistically significant difference in postoperative overall complications between the two groups (P=0.073). Compared with the PS group, the length of stay was significantly shorter (P<0.001), hospital costs were significantly less (P<0.001), OS was significantly better in the combination group (P=0.017). The subgroup analysis further suggested that the advantage of combined therapy was more obvious in patients with hilar cholangiocarcinoma than that in distal cholangiocarcinoma. PS treatment (HR=2.665, 95% CI: 1.544-4.564, P<0.001), higher preoperative level of carbohydrate antigen 19-9 (HR=2.031, 95% CI: 1.201-3.432, P=0.008) and lower level of ALB (HR=1.908, 95% CI: 1.130-3.221, P=0.016) were independent predictors of worse OS.

Conclusions

Compared with PS, biliary stent combined with 125I seeds implantation may significantly shorten the length of stay, reduce hospital costs, and prolong survival, without increasing the overall complications in advanced EHCC patients, which is worthy of further popularization and application in clinical practice.
