RESUMEN
Objective:To determine the risk factors for development of combined hepatocellular-cholangiocarcinoma (CHC) and intrahepatic cholangiocarcinoma (ICC).Methods:The clinical data of patients with ICC or CHC confirmed by pathology at Henan Provincial People's Hospital from January 2012 to December 2018 were retrospectively analyzed. Of 225 patients with ICC or CHC, there were 90 males and 135 females, aged (58.7±10.4) years old. Based on the pathological type, there were 172 patients in the ICC group and 53 patients in the CHC group. The healthy control group was selected from 450 individuals who underwent routine health examination in the same hospital, and there were 189 males and 261 females, aged (56.7±9.3) years old. Univariate and multivariate logistic regression were used to analyze the risk factors of ICC and CHC.Results:The risk factors of ICC included hepatitis B surface antigen (HBsAg) (+ )/hepatitis B core antibody (anti-HBc) (+ ) ( OR=9.373, 95% CI: 4.784-18.363, P<0.001), hepatitis C virus antibody (HCV-Ab) (+ ) ( OR=7.151, 95% CI: 1.195-42.776, P=0.031), diabetes mellitus ( OR=3.118, 95% CI: 1.733-5.612, P<0.001) and hepatolithiasis ( OR=18.650, 95% CI: 5.210-66.767, P<0.001). The risk factors of CHC included HBsAg (+ )/anti-HBc(+ )( OR=54.891, 95% CI: 17.434-172.822, P<0.001) and HCV-Ab (+ ) ( OR=37.785, 95% CI: 5.720-249.611, P<0.001). Conclusion:HBV infection, HCV infection, hepatolithiasis, diabetes mellitus and cirrhosis were risk factors for ICC. HBV and HCV infection were risk factors of CHC.
RESUMEN
Objective:To analyze the expression of mucin 1 (MUC1) and Ki67 in intrahepatic cholangiocarcinoma (ICC), and to explore the correlations between the expression of MUC1 and Ki67 and the clinicopathological features and prognosis of ICC patients.Methods:Clinical data of 398 patients with ICC admitted to Henan Provincial People's Hospital from January 2013 to March 2020 were retrospectively analyzed. A total of 104 patients were included in this study, including 67 males and 37 females, aged (56.6±9.3) years. Immunohistochemistry was used to detect the expression of MUC1 and Ki67 in cancer tissues. Univariate and multivariate Cox regression analysis were used to study the prognostic factors of ICC patients.Results:The expression of MUC1 was low in 65 patients and high in 39 patients. Ki67 expression was low in 52 patients and high in 52 patients. High expression of MUC1 was correlated with lymph node metastasis ( P<0.05), while high expression of Ki67 was correlated with tumor nodes number, lymph node metastasis and vascular invasion (all P<0.05). Multivariate analysis showed that ICC patients with high MUC1 expression ( HR=2.321, 95% CI: 1.420-3.792, P<0.001) and high Ki67 expression ( HR=2.012, 95% CI: 1.247-3.247, P=0.004) showed a poor prognosis after hepatectomy. ICC patients with high MUC1 expression ( HR=1.664, 95% CI: 1.058-2.618, P=0.028) and high Ki67 expression ( HR=1.883, 95% CI: 1.168-3.035, P=0.009) had a poor prognosis after hepatectomy. Conclusion:High expression of MUC1 and Ki67 is correlated with tumor growth and metastasis. MUC1 and Ki67 are independent risk factors for prognosis of ICC patients after hepatectomy.
RESUMEN
Objective:To analyze the clinicopathological features, diagnosis and treatment of neuroendocrine carcinoma of gallbladder (GB-NEC).Methods:The clinical data of 17 patients with GB-NEC confirmed by postoperative pathology managed at the People's Hospital of Zhengzhou University from March 2013 to January 2020 were analyzed retrospectively. There were 9 males and 8 females, with an age of (68.9±11.2) years. The clinical and follow-up data were analyzed.Results:The main clinical manifestations were abdominal pain ( n=9, 52.9%), anorexia ( n=5, 29.4%), jaundice ( n=2, 11.8%), abdominal mass ( n=2, 11.8%), and asymptomatic ( n=2, 11.8%). Radical resection of gallbladder carcinoma was performed in 9 patients, and palliative resection in 8 patients. Postoperative chemotherapy was given to 4 patients. Postoperative pathology showed small cell type in 11 patients and large cell type in 6 patients. Immunohistochemical staining showed synaptophysin positivity in 17 patients (100.0%), chromogranin A positivity in 12 (70.6%), Ki67 positivity in 17 patients (100%, >50% was defined as positive). All 17 patients were followed-up from 78 to 745 days, with a median of 237 days. At the time of censor of this study, 13 patients had died. The 1-and 2-year cumulative survival rates were 26.5% and 19.9%, respectively. The 1- and 2-year cumulative survival rates of radical gallbladder carcinoma resection ( n=9) were 44.4% and 33.3%, respectively. Eight patients underwent palliative resection, and the longest follow-up time was 276 days. Conclusion:This study showed the incidence of GB-NEC was low. There was no specific clinical manifestations, and the diagnosis mainly depended on immunohistochemistry. Patients with GB-NEC had high expressions of Ki67 and had poor prognosis. Early radical resection was helpful to improve survival of these patients.
RESUMEN
Objective To evaluate the role of tumor budding in the prognostic value of intrahepatic cholangiocarcinoma(ICC) after radical resection.Methods The clinicopathological data of patients undergoing radical resection for intrahepatic cholangiocarcinoma between 2011 and 2016 were retrospectively analyzed.The number of tumor budding was counted in a ×200 microscopic field (0.785mm2).Based on receiver operation curve (ROC),the number of tumor budding ≥ 15 was defined as high-grade group,and ＜ 15 was low-grade group.Multivariate analysis were performed on predictors of the tumor.Results Low-grade group was observed in 32 cases and high-grade group in 50.High-grade group appeared to develop tumors with higher CA199,poor differentiation,larger tumor diameter,advanced stage and high risks of lymphnode metastasis (respectively x2 =5.470,4.359,5.101,4.696,5.960,all P ＜ 0.05).Univariate analysis showed that tumor budding,CA199,differentiation,tumor diameter,T classification and lymphnode metastasis were related to the overall survival of patients with ICC (respectively x2 =11.704,4.876,5.056,5.152,8.442,16.725,all P ＜ 0.05).On multivariable analysis,high-grade group was a significant independent predictor of worse OS (HR =2.707 95％ CI 1.558-4.705,P ＜ 0.001).Conclusions High-grade tumor budding is an important negative prognostic factor for ICC.
