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.

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.

Objective To explore the feasibility and safety of laparoscopic hepatectomy in the treatment of hepatic malignant tumors.Methods 136 liver cancer patients were divided into:laparoscopic surgery group (LR group,51 cases) and open surgery group (OR group,85 cases).Serum enzyme,inflammatory factors and postoperative complications were compared between the 2 groups.Results The operative time of LR group was significantly longer than that of OR group (252 ± 123) min vs.(169 ± 63 min),hospitalization time (10 ± 5) d vs.(12 ± 5) d and intraoperative blood loss in LR group were lower than those in OR group (381 ±156) ml vs.(523 ±325) ml (all P＜0.05).ALT,AST,ALP in LR group was significantly lower than that in OR group [ALT:(227 ±101) U/L vs.(690 ±575) U/L,AST:(187±107) U/Lvs.(551 ±529) U/L,ALP:(63 ±25)U/Lvs.(86 ±40)U/L,allP＜0.05].Prothrombin time in LR group was shorter than that in OR group [(14.3 ±0.8) s vs.(15.3 ± 1.6)s,P =0.000].The postoperative IL-6,TNF-α in LR group was lower than that in OR group [IL-6:(154 ±31)pg/ml vs.(182 ±34) pg/ml,TNF-α:(22 ±6) pg/ml vs.(30 ±7) pg/ml,all P ＜0.05].Postoperative complications in laparoscopic group were significantly lower than those in laparotomy group (3.9％ vs.11.8％,P ＜ 0.05).Conclusions Laparoscopic resection of liver malignant tumors is safer and has less complications,lower inflammatory stress response and liver injury.
