ABSTRACT
Objective:
To study the relationship between morphologic classification and prognosis of patients with intrahepatic cholangiocarcinoma (ICC).Methods:
The clinicopathologic data of 125 ICC patients who underwent R 0 resection at the Ningbo Medical Center Li Huili Hospital from January 2011 to May 2019 were retrospectively analyzed. This cohort consisted of 67 males and 58 females, aged 26.0 to 82.0 (63.5±9.5) years old. Based on the resected specimens, the patients were divided into the mass forming type, periductal infiltrating type and mixed type. The survival rates and recurrence-free survival outcomes of the patients among the three types were compared, and the risk factors that influenced prognosis were analyzed.Results:
Using the predetermined inclusion and exclusion criteria, 16 patients with missing data and other causes of death were excluded from the initial 125 patients. Also, as the number of the mixed type was small, these patients were excluded. Finally 62 patients in the mass forming type and 42 patients in the periductal infiltrating type were analyzed. In the mass forming group, there were 32 males and 30 females, aged (63.1±9.1) years. In the perivascular infiltration group, there were 22 males and 20 females, aged (64.1±10.2) years. The 1-, 3-, 5-year survival rates of the mass forming group were 78.1%, 33.2%, 18.9% (median survival 25 months). The 1-, 3-, 5-year survival rates of the periductal infiltrating type were 63.3%, 8.3%, 6.1% (median survival 15 months). There were statistically significant differences between the two groups ( P<0.05). The median recurrence-free survival for the mass forming and the periductal infiltrating groups were 18 and 11 months, respectively, with a statistically significant differences between them ( P<0.05). Univariate and multivariate analysis showed that TNM staging Ⅲ~Ⅳ ( HR=2.966, 95% CI 1.549-5.679) and periductal infiltrating type ( HR=2.403, 95% CI 1.236-4.670) were independent risk factors for survival of these patients after operations. TNM staging Ⅲ~Ⅳ ( HR=2.466, 95% CI 1.325-4.589), low grade differentiation ( HR=0.528, 95% CI 0.299-0.934) and periductal infiltrating type ( HR=2.432, 95% CI 1.295-4.565) were independent risk factors for relapse-free survival of these patients ( P<0.05).Conclusions:
Morphological classification was found to be an independent risk factor for prognosis of ICC patients in this study, with significantly worse long-term prognosis when compared with the mass forming type.
