Objective: To establish a survival prediction model based on the independent prognostic factors of long-term prognosis after laparoscopic liver resection(LLR) for intrahepatic cholangiocarcinoma(ICC). Methods: The clinical and pathological data of 351 consecutive patients with ICC who received radical LLR in 13 Chinese medical centers from August 2010 to May 2021 were collected retrospectively. There were 190 males and 161 females,aged(M(IQR)) 61(14)years(range:23 to 93 years). The total cohort was randomly divided into a training dataset(264 cases) and a validation dataset(87 cases). The patients were followed up by outpatient service or telephone,and the deadline for follow-up was October 2021. Based on the training dataset,the multivariate Cox proportional hazards regression model was used to screen the independent influencing factors of long-term prognosis to construct a Nomogram model. The Nomogram model's discrimination,calibration,and clinical benefit were evaluated through internal and external validation,and an assessment of the overall value of two groups was made through the use of a receiver operating characteristic(ROC) curve. Results: There was no significant difference in clinical and pathological characteristics and long-term survival results between the training and validation datasets(all P>0.05). The multivariate Cox analysis showed that CA19-9,CA125,conversion to laparotomy during laparoscopic surgery,and lymph node metastasis were independent prognostic factors for ICC patients after LLR(all P<0.05). The survival Nomogram was established based on the independent prognostic factors obtained from the above screening. The ROC curve showed that the area under the curve of 1, 3 and 5-year overall survival rates of patients in the training dataset were 0.794(95%CI:0.721 to 0.867),0.728(95%CI:0.618 to 0.839) and 0.799(95%CI:0.670 to 0.928),and those in the validation dataset were 0.787(95%CI:0.660 to 0.915),0.831(95%CI:0.678 to 0.983) and 0.810(95%CI:0.639 to 0.982). Internal and external validation proved that the model exhibited a certain discrimination,calibration,and clinical applicability. Conclusion: The survival Nomogram model based on the independent influencing factors of long-term prognosis after LLR for ICC(including CA19-9,CA125,conversion to laparotomy during laparoscopic surgery,and lymph node metastasis) exhibites a certain differentiation,calibration,and clinical practicability.

OBJECTIVETo compare the predictive values of eight staging systems for primary liver cancer in the prognosis of combined hepatocellular-cholangiocellular carcinoma (cHCC-CC) patients after surgery.

METHODSThe clinical data of 54 cHCC-CC patients who underwent hepatectomy or liver transplantation from May 2005 to Augest 2013 in Chinese PLA General Hospital were collected. We evaluated the prognostic value of the Okuda staging system, Cancer of the Liver Italian Program (CLIP) score, French staging system, Barcelona Clinic Liver Cancer (BCLC) staging system, 7th edition of tumour-node-metastasis (TNM) staging system for hepatocellular carcinoma and intrahepatic cholangiocarcinoma (ICC), Japan Integrated Staging (JIS) score, and Chinese University Prognostic Index. The distribution, Kaplan-Meier method, Log-rank test, and area under a receiver operating characteristic curve were used to compare the prognosis-predicting ability of these different staging systems in 54 cHCC-CC patients after surgery.

RESULTSThe TNM staging system for ICC and JIS score had a better distribution of cases. The 12-and 24-month survivals of the entire cohort were 65.5% and 56.3%, respectively. A Log-rank test showed that there was a significant difference existing in the cumulative survival rates of different stage patients when using TNM staging system for ICC (stage 1 vs. stage 2, P=0.012; stage 2 vs. stage 3-4, P=0.002), Okuda staging system (stage 1 vs. stage 2, P=0.025), and French staging system (stage A and stage B, P=0.045). The 12-and 24-month area under curve of TNM staging system for ICC, BCLC staging system, JIS score, and CLIP score were 0.836 and 0.847, 0.744 and 0.780, 0.723 and 0.764, and 0.710 and 0.786, respectively.

CONCLUSIONThe 7th edition of TNM staging system for ICC has superior prognostic value to other seven staging systems in cHCC-CC patients undergoing surgical treatment.

Extrahepatic cholangiocarcinoma is often clinically challenging to diagnose. Even multidisciplinary approaches which include computed tomography, magnetic resonance imaging, and endoscopic retrograde cholangiography are unsatisfactory in some cases, especially with biliary stricture. Percutaneous transhepatic cholangioscopy (PTCS) with its direct visualization for biopsy appears to be a promising technique for detecting cholangiocarcinoma at an early stage. We report a case of adenocarcinoma in situ of the distal common bile duct (CBD) that was confirmed by PTCS. This case suggests the useful role of PTCS in the differential diagnosis of a distal CBD obstruction, particularly when other diagnostic modalities do not provide definitive information.

Xanthogranulomatous cholecystitis (XGC) is an unusual and destructive inflammatory process that is characterized by thickening of the gallbladder (GB) wall with a tendency to adhere to neighboring organs. XGC is often mistaken for GB carcinoma, and the frequency of the coexistence of these two lesions is approximately 10%. Therefore, in case of severe XGC, there is chance of either overlooking the carcinoma or other significant lesions. CA 19-9 is commonly measured in the serum of patients with hepatobiliary malignancies. Although CA 19-9 can be elevated in benign conditions such as cholestasis, pancreatitis, tuberculosis, thyroid disease etc., malignancy should be considered at first in setting of its significant and persistent elevation. We report a case of a 62-year-old man who showed continuously rising level of CA19-9 over 2000 U/mL after cholecystectomy for xanthogranulomatous cholecystitis and finally was diagnosed as cholangiocarcinoma by short-term follow up.

OBJECTIVETo report the experience in surveillance and early detection of cholangiocarcinoma (CC) and in using en bloc total hepatectomy-pancreaticoduodenectomy-orthotopic liver transplantation (OLT-Whipple) to achieve complete eradication of early-stage CC complicating primary sclerosing cholangitis (PSC).

METHODSAsymptomatic PSC patients underwent surveillance using endoscopic ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) with multilevel brushings for cytological evaluation. Patients diagnosed with CC were treated with combined extra-beam radiotherapy, lesion-focused brachytherapy, and OLT-Whipple.

RESULTSBetween January 1988 and February 2001, 42 of 119 PSC patients were followed according to the surveillance protocol. CC was detected in 8 patients, 6 of whom underwent OLT-Whipple. Of those 6 patients, 4 had stage I CC, and 2 had stage II CC. All 6 OLT-Whipple patients received combined external-beam and brachytherapy radiotherapy. The median time from diagnosis to OLT-Whipple was 144 days. One patient died 55 months post-transplant of an unrelated cause, without tumor recurrence. The other 5 were well without recurrence at 79, 82, 108, 128, 129 and 145 months.

CONCLUSIONSFor patients with PSC, ERCP surveillance cytology and intralumenal endoscopic ultrasound examination allow for early detection of CC. Broad and lesion-focused radiotherapy combined with OLT-Whipple to remove the biliary epithelium en bloc offers promising long-term, tumor-free survival. All patients tolerated this extensive surgery well with good quality of life following surgery and recovery. These findings support consideration of the complete excision of an intact biliary tree via OLT-Whipple in patients with early-stage hilar CC complicating PSC.

OBJECTIVETo investigate the surgical treatment for hilar cholangiocarcinoma(HCCA) of Bismuth-Corlette type IV.

METHODSThe clinical data of 73 HCCA patients admitted in Southwest Hospital, the Third Military Medical University from January 2002 to December 2008 were analyzed retrospectively. There were 41 males and 32 females, aged from 30 to 84 years old (averaged, 56.8 years old). All patients were diagnosed as hilar mass with hilar biliary obstruction by B-ultrasound, CT, magnetic resonance imaging, endoscopic retrograde cholangiopancreatography, magnetic resonance cholangiopancreatography or percutaneous transhepatic cholangiography, and confirmed by pathological examination in intra-operation and post-operation. Diagnosis of all patients were according to Bismuth-Corlette type IV.

RESULTSFifteen cases underwent percutaneous transhepatic cholangial drainage, stents were implanted in 8 patients. Simple internal drainage was performed on 25 of the 73 patients and 4 with palliative resection. Radical resection was performed on 19 patients. The radical resection rate of HCCA were 26.0%. The 1, 3 years of survival rates were 36.8%, 10.5% respectively. The 1 year survival rate was 6.3% in drainage group.

CONCLUSIONRadical resection is the potentially curative treatment for HCCA, a sufficient, reasonable use of internal and external drainage would improve the patient's quality of life.
