Clinical features and prognosis analysis of gallbladder cancer after radical resection in elderly patients / 国际外科学杂志

ABSTRACT

Objective To clarify the characteristics and postoperative benefit of gallbladder carcinoma in elderly patients (≥ 65 years old).Methods Two hundred and seventy-three patients of gallbladder carcinoma were collected,who were treated intent resection from January 2004 to December 2012 in the Department of Hepatobiliary Surgery,Eastern Hepatobiliary Hospital,Second Military Medical University.More than 65 years old was defined as the elderly,else was defined as the younger.The clinical-pathological features and prognosis of 85 elderly patients(elderly group) and 188 younger patients (younger group) were retrospectively analyzed.The survival of patients were followed up by telephone or outpatient.The incidence of hypertension,incidence of diabetes,TNM staging,and median CA19-9 were compared between the two groups.Continuous variables using a two-sample t test or Mann-Whitney U test.Categorical variables were compared by the Chi-square test or Fisher probability method.The survival curve was drawn by the Kaplan-Meier method.The univariate analysis and multivariate analysis of prognosis were respectively done using the Log-rank test and COX regression model.Results The incidence of hypertension,incidence of diabetes,TNM stage ratio (Ⅲ + Ⅳ/Ⅰ + Ⅱ),and CA19-9 median in the elderly group were 30.6％,11.8％,27.6 and 69.3 U/ml,respectively.The differences in the younger group were 13.8％,4.8％,7.9 and 28.2 U/ml,respectively,with statistically significant difference between the two groups (all P ＜ 0.05).The incidence of complications was 54.1％ in the elderly group and 48.9％ in the younger group,with no significant difference between the two groups (P =0.302).The median survival of the elderly group was 28.01 months,and the median survival of the younger group was 36.20 months,with no statistical difference between the two groups (P =0.131).Cox analysis showed that independent prognostic risk factors for the elderly patients with gallbladder cancer included liver invasion (HR =2.386,95％ CI1.379-4.127,P =0.002) and lymph node metastasis (HR =1.866,95 ％ CI1.100-3.167,P =0.021).Conclusions Radical resection is safe and feasible for elderly patients with gallbladder carcinoma.Age is not a contraindication for surgery.Radical resection can get the same benefits as young people.Liver invasion and lymph node metastasis are independent risk factors affecting the prognosis of the elderly patients with gallbladder carcinoma.
