Intrahepatic cholangiocarcinoma (ICC) is the second most common primary malignant tumor in the liver after hepatocellular carcinoma. Its incidence and mortality rates have increased worldwide in recent years. Surgical resection is the best treatment modality for ICC;however,the overall prognosis remains poor. Accurate evaluation of post operative prognosis allows personalized treatment and improved long-term outcomes of ICC. The American Joint Commission on Cancer TNM staging manual is the basis for the standardized diagnosis and treatment of ICC;however,the contents of stage T and stage N need to be improved. The nomogram model or scoring system established in the analysis of commonly used clinicopathological parameters can provide individualized prognostic evaluation and improve prediction accuracy;however,more studies are needed to validate the results before clinical use. Meanwhile,imaging features exhibit great potential to establish the post operative prognosis evaluation system for ICC. Molecular-based classification provides an accurate guarantee for prognostic assessment as well as selection of populations that are sensitive to targeted therapy or immunotherapy. Therefore,the establishment of a prognosis evaluation system,based on clinical and pathological characteristics and centered on the combination of multidisciplinary and multi-omics,will be conducive to improving the long-term outcomes of ICC after surgical resection in the context of big medical data.

Combined hepatocellular-cholangiocarcinoma is a rare form of primary liver cancer showing features of both hepatocellular and biliary epithelial differentiation. We report here on a case with collision tumor, which apparently was the coincidental occurrence of both hepatocellular carcinoma and cholangiocarcinoma underlying schistosomiasis. A 39-year-old-Philippine female was transferred to our hospital for evaluation of a liver mass that was found on ultrasonography at a local hospital. HBsAg and Anti-HCV were negative and serum alpha-fetoprotein (AFP) level was normal. The tumor mass was histologically diagnosed as adenocarcinoma by sono-guided biopsy before the operation. Partial lobectomy was performed and we histologically identified the concurrent occurrence of hepatocellular carcinoma and cholangiocarcinoma, (a "collision type carcinoma").

OBJECTIVE: To explore the technique and effect of liver hanging maneuver in anterior approach for isolated complete liver caudate lobectomy. METHODS: We recruited 17 patients with liver caudate lobe tumor (13 primary hepatocellular carcinoma, 3 cholangiocarcinoma and 1 liver metastasis from colorectal cancer). Isolated complete caudate lobectomy with liver hanging maneuver was performed in 17 patients. RESULTS: All 17 patients were successfully received the above-mentioned operation. The operative time was 166-427 (211.5 ± 20.1) min and the intraoperative blood loss was 372-1 208 (472.7 ± 83.6) mL. There was no operative death. The survival rates of follow up for 1, 3 and 5 years were 76.5%, 52.9% and 23.5%, respectively. CONCLUSION Liver hanging maneuver for isolated complete resection of the caudate lobe is an ideal approach for liver neoplasms resection.

Objective: To examine the significance and prognostic value of the classification of hilar cholangiocarcinoma based on actual anatomical location. Methods: A retrospective study was conducted including 120 patients of hilar cholangiocarcinoma treated at the Second Affiliated Hospital,Zhejiang University School of Medicine and Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to December 2021. Patients with hilar cholangiocarcinoma were classified for seven types according to the site of tumor location. The clinicopathological and prognostic data of 120 patients were retrospectively analyzed(There were 57 males and 63 females,the age (M(IQR)) was 61(22)years(range:42 to 85 years)). All patients received radical resection without visible intraoperative tumor residue and negative bile duct resection margin according to intraoperative pathological biopsy. The classification variables were analyzed by Pearson χ² test or Fisher's exact probability test,one-way ANOVA or Kruskal-Wallis rank sum test.Kaplan-Meier method was used for survival analysis. Cox proportional risk model was used for prognostic factors. Results: The coincidence rate of preoperative surgical planning and actual operational styles was verified in 33 cases. Twenty-six cases were consistent,and 7 cases were inconsistent,with a coincidence rate of 78.8%. According to the actual anatomical location,patients in type of secondary branch experienced a significantly longer operation duration,a higher portal vein resection rate,margin positive rate and more advanced T stage(all P<0.05). The median overall survival time of the unilateral main trunck group was 27.0 months,and the bilateral group was 17.0 months. Survival analysis based on the tumor classification of the actual anatomical location showed that the unilateral or main trunck group predicted less aggressive clinical features and favorable outcomes(HR=1.931,95%CI:1.066 to 3.499,P<0.05). Multivariate analysis demonstrated that the actual anatomical location of the tumor type(HR=2.269,95%CI:1.333 to 3.861,P=0.003),combined liver resection(HR=0.464,95%CI:0.253 to 0.848,P=0.013) and N stage(HR=6.317,95%CI:3.083 to 12.944,P<0.01) were independent factors affecting the prognosis of patients. Conclusion: The classification based on the actual anatomy can be used as a promising scheme in refining patient stratification and predicting survival in hilar cholangiocarcinoma,and it can guide the selection of surgical methods,and predict operative safety and radical resection rate.

OBJECTIVETo investigate the resection technique for small hepatocellular carcinoma (SHCC) in special sites and discuss their outcome.

METHODSClinicopathological data of 30 patients with SHCC in special sites undergone liver resection were reviewed. There were 29 cases of hepatocellular carcinoma and 1 case of cholangiocarcinoma, confirmed by pathology. The tumor was close to the first porta hepatis in 8 cases, colse to the second porta hepatis in 15 cases, and close to the third porta hepatis in 7 cases. Twenty-five patients had one lesion, 4 patients had two and the other had three. The tumor diameter was (2.7 ± 1.2) cm.

RESULTSNo perioperative death occurred. The operation time was (279 ± 101) min, the mean intraoperative blood loss was 566 ml, and the postoperative hospitalization was (10.5 ± 2.7) days. The 1- and 3-year survival rates were 100% and 83.3%, respectively, and the 1- and 3-year disease free survival rates were 85.0% and 41.3%, respectively.

CONCLUSIONAlthough the surgery for SHCC in special sites is quite difficult and risky, surgical treatment is still safe with good perioperative management and is an effective treatment of SHCC in special sites.
