Anatomical location as a prognostic factor in surgical treatment of gallbladder carcinoma / 中华肝胆外科杂志

ABSTRACT

Objective:To explore the prognostic factors of patients with gallbladder cancer in different anatomical locations.Methods:A retrospective analysis of the clinical data of 140 patients with gallbladder cancer who were surgically treated in the 904 Hospital of the Joint Logistics Support Force from January 2015 to December 2015. Among them, 49 were males and 91 were females, with a median age of 64.0 years. According to the location of gallbladder cancer, they were divided into the neck of the gallbladder and the bottom of the gallbladder. The clinical data of the two groups were compared. The Kaplan-Meier method was used for univariate analysis, and Cox multivariate regression analysis was used to analyze the significant factors of univariate survival to determine the independent risk factors that affect the prognosis of patients with gallbladder cancer. Use Pearson correlation to analyze the correlation between clinicopathological characteristics.Results:Patients in the neck of the gallbladder group had higher levels of preoperative total bilirubin, preoperative albumin, carcinoembryonic antigen, carbohydrate antigen 19-9, extrahepatic bile duct resection (biliary-enteric anastomosis), radical resection, breakthrough of the liver/serous membrane invasion, lymph node metastasis, TNM staging, local recurrence in the operation area in the surgical area were statistically significant ( P<0.05). Univariate analysis suggested that preoperative jaundice, Glasgow prognostic score (GPS), C-reactive protein, carcinoembryonic antigen, carbohydrate antigen 19-9, accidental gallbladder cancer, surgical method, tumor pathological type, tumor differentiation degree, tumor growth location (neck than the bottom of the body) are related to the prognosis (all P<0.05). Cox regression analysis indicated that GPS ( RR=3.272, 95 CI 1.987-5.388), surgical method ( RR=4.149, 95 CI 2.561-6.723), tumor location ( RR=0.316, 95 CI 0.209-0.478), distant metastasis ( RR=1.695, 95 CI 1.036-2.775) and TNM staging ( RR=3.686, 95 CI 2.222-6.115) are independent risk factors affecting the prognosis of gallbladder cancer. Correlation analysis suggests that neck tumors are related to later staging, liver bile duct invasion, lymph node metastasis, high inflammation levels, and low radical cure rates. Conclusions:Gallbladder cancer that occurs in the neck of the gallbladder is an independent factor influencing the poor prognosis of patients with surgical treatment. In addition, TNM staging, distant metastasis and Glasgow score are important predictors of survival in patients with gallbladder cancer.
