Abstract:
Objective:To compare the clinicopathological features between patients with gallbladder adenosquamous carcinoma and gallbladder adenocarcinoma, and analyze the prognostic factors for overall survival.Methods:The clinical data of 135 patients with gallbladder cancer, confirmed by postoperative pathology, treated in Department of Hepatobiliary and Pancreatic Surgery of Ningbo Medical Center Lihuili Hospital within 5 years (from January 2018 to December 2022) were retrospectively analyzed. A total of 122 patients were enrolled in this study, including 55 males and 67 females, aged (68.0±9.8) years. Patients were divided into the adenosquamous carcinoma group ( n=14) and adenocarcinoma group ( n=108). The clinicopathological features (tumor size, differentiation of tumor, tumor TNM stage) and survivals of patients were compared. The survival rates were analyzed using the Kaplan-Meier method and log-rank test. Multivariate Cox regression analysis was performed to identify prognostic factors for overall survival. Results:Compared with the adenocarcinoma group, patients with adenosquamous carcinoma had a larger tumor size, higher incidence of liver invasion, higher proportion of poor differentiation of tumor, higher proportion of TNM stage Ⅲ-Ⅳ (all P<0.05). There was also a statistically significant difference in the extent of liver resection between the two groups ( χ2=9.22, P=0.016). The 1- and 2-year cumulative survival rates after surgery in adenosquamous carcinoma group were 28.6% and 9.5%, respectively, lower than those in adenocarcinoma group (78.7% and 60.5%, respectively; χ2=27.88, P<0.001). For patients with gallbladder adenosquamous carcinoma, the cumulative survival rate of patients who received postoperative adjuvant chemotherapy ( n=11) was significantly better than that of patients without postoperative adjuvant chemotherapy ( n=3) ( χ2=5.82, P=0.016). For patients with gallbladder adenocarcinoma, multivariate Cox regression analysis identified that the N stage (N 1/N 0HR=4.521, 95% CI: 1.399-14.612, P=0.012; N 2/N 0HR=8.644, 95% CI: 2.407-31.039, P=0.001) and M stage (M 1/M 0HR=4.699, 95% CI: 1.540-14.340, P=0.007) were associated with a poor survival. Conclusions:Compared to gallbladder adenocarcinoma, adenosquamous carcinoma had more aggressive features and a worse prognosis. For patients with gallbladder adenosquamous carcinoma, postoperative adjuvant chemotherapy was associated with an improved overall survival. For patients with gallbladder adenocarcinoma, N stage and M stage were independent risk factors for overall survival.
