Abstract:
Objective:To examine the correlation between perineural invasion and clinicopathological factors and the role of perineural invasion on the prognosis of patients with curatively resected gallbladder carcinoma.Methods:The clinicopathological and follow-up data of 548 patients with gallbladder carcinoma who underwent radical surgery from the First Affiliated Hospital of Xi′an Jiaotong University from January 2013 to December 2020 were analyzed retrospectively. There were 173 males and 375 females,with age( M(IQR)) of 62(14)years(range:30 to 88 years). The correlations between perineural invasion and the clinicopathological features were analyzed. The relationship between prognosis and clinicopathological factors were further analyzed. The survival curve was drawn using the Kaplan-Meier method. The univariate analysis and multivariate analysis were done using the Log-rank test and Cox proportional hazard model respectively. Results:Radical resection was performed in 548 cases,including 59 cases(10.8%) with perineural invasion. The results of univariate analysis showed that perineural invasion was related to serum bilirubin level,serum carcinoembryonic antigen(CEA) level,CA19-9 level,T stage,lymph node metastasis,liver invasion,vessel invasion and tumor location(all P<0.05).The results of multivariate analysis showed that jaundice,high-level serum CA19-9,high-level serum CEA,T4 stage,vessel invasion and tumor located in the neck or cystic duct of the gallbladder were independent risk factors of perineural invasion in gallbladder carcinoma. Survival of 367 patients in T3-T4 stages were analyzed. The prognosis of gallbladder carcinoma patients with perineural invasion was significantly worse than that of patients without perineural invasion(median survival time:12.0 months vs. 34.7 months, P<0.01). Univariate analysis showed that perineural invasion,gallbladder stones,gallbladder polyps,CA125,CEA,CA19-9,serum bilirubin level,tumor location,N stage,liver invasion and pathological differentiation were independent risk factors affecting prognosis of patients with gallbladder carcinoma(all P<0.05). The results of Cox proportional hazard model showed that perineural invasion,N stage,liver invasion,gallbladder stones,pathological differentiation were independent risk factors affecting prognosis of patients with gallbladder carcinoma(all P<0.05). Conclusions:Jaundice,high-level serum CA19-9,high-level serum CEA,T4 stage,vessel invasion and tumor located in the neck or cystic duct of the gallbladder are independent risk factors for perineural invasion of gallbladder carcinoma. Perineural invasion is one of the independent risk factors affecting the prognosis of T3-T4 stage gallbladder carcinoma.
