BACKGROUND: Reports of liver transplantation (LT) in patients with mixed hepatocellular carcinoma/cholangiocarcinoma (HCC/CC) and intrahepatic cholangiocarcinoma (ICC) are modest and have been mostly retrospective after pathological categorization in the setting of presumed HCC. Some studies suggest that patients undergoing LT with small and unifocal ICC or mixed HCC/CC can achieve about 40%-60% 5-year post-transplant survival. The study aimed to report our experience in patients undergoing LT with explant pathology revealing HCC/CC and ICC...

Isolated brain metastases prior to locoregional recurrence from hilar cholangiocarcinoma (HCCA) following curative resection are an extremely rare event. Very few reports regarding brain metastasis prior to locoregional recurrence following curative resection have been published due to the fact that to differentiate brain metastases from HCCA recurrence is challenging, particular in the early stages, since the neurological findings of brain metastasis are occult and subtle. Any patient with HCCA who has undergone radical resection and subsequently presented with a further onset of neurological symptoms should be evaluated for brain involvement...

The epidemiology of infection after liver transplantation for hilar cholangiocarcinoma has not been systematically investigated. In this study of 124 patients, 255 infections occurred in 105 patients during the median follow-up of 4.2 years. The median time to first infection was 15.1 weeks (IQR 1.6 - 62.6). The most common sites were the abdomen, bloodstream and musculoskeletal system. Risk factors for any post-transplant infection were pre-transplant VRE colonization (Hazard Ratio [HR] 1.9, p=0.002), living donor transplantation (HR 6...

BACKGROUND: Extensive resection for hilar cholangiocarcinoma is the most effective treatment, but high morbidity and poor prognosis remain concerns. Previous data have shown marked differences in outcomes between comparable Eastern and Western centers. We compared the outcomes of the management for hilar cholangiocarcinoma at one Japanese and one British institution with comparable experience. METHODS: Of 298 consecutive patients with hilar cholangiocarcinoma evaluated at Hirosaki University Hospital, Japan and St...

REVIEW
Amar Gupta, Elijah Dixon
Intrahepatic cholangiocarcinoma (ICC) is a rare entity with a distinct clinical course and epidemiology from hilar and extrahepatic cholangiocarcinoma. ICC makes up 8-10% of cholangiocarcinomas and 10-20% of all primary liver tumors. There remains a considerable amount of geographic variation in the incidence of ICC worldwide; however, the overall incidence of this malignancy appears to be rising. Several risk factors have been identified, such as infectious causes (liver flukes, viral hepatitis), biliary tract disease [primary sclerosing cholangitis (PSC), hepaticolithiasis, biliary cystic diseases], metabolic syndrome, lifestyle choices (alcohol abuse, tobacco use), and cirrhosis...

BACKGROUND: To investigate the predictive values of preoperative and postoperative serum CA19-9 levels on survival and other prognostic factors including early recurrence in patients with resectable hilar cholangiocarcinoma. RESULTS: In univariate analysis, increased preoperative and postoperative CA19-9 levels in the light of different cut-off points (37, 100, 150, 200, 400, 1000 U/ml) were significantly associated with poor survival outcomes, of which the cut-off point of 150 U/ml showed the strongest predictive value (both P < 0...

Percutaneous transhepatic biliary drainage (PTBD) catheter site metastasis in cases of cholangiocarcinoma is reported sporadically. But it is unusual to see left-sided tumour metastasising to the right PTBD catheter site. Metastasis, in general, has a poor prognosis, but recurrence along the catheter tract in the absence of other systemic diseases can be a different scenario altogether. To date, there is no consensus on the management of this form of metastasis. But carefully selected patients can benefit from aggressive surgical resection...

Cholangiocarcinoma (CC) is a type of relatively rare neoplasm in adenocarcinoma. The characteristics of CCs as well as biliary epithelial cells are heterogeneous at the different portion of the biliary tree. There are two candidate stem/progenitor cells of the biliary tree, i.e., biliary tree stem/progenitor cell (BTSC) at the peribiliary gland (PBG) of large bile ducts and liver stem/progenitor cell (LPC) at the canals of Hering of peripheral small bile duct. Although previous reports suggest that intrahepatic CC (ICC) can arise from such stem/progenitor cells, the characteristic difference between BTSC and LPC in pathological process needs further investigation, and the etiology of CC remains poorly understood...

BACKGROUND: Radiofrequency ablation (RFA) causes coagulative necrosis of tissue and may be beneficial prior to biliary stenting. We report our experience using RFA for malignant biliary obstruction and review the literature. METHODS: Retrospective analysis of all patients undergoing RFA for malignant biliary obstruction over the last two years. Success, complications and re-intervention following RFA were assessed. Controls were age, sex and disease matched who had stenting alone...

Intrahepatic cholangiocarcinomas were classified into two types based on their microscopic appearance. Tumors with histologic similarities to hilar cholangiocarcinomas (predominantly ductal adenocarcinomas with minor tubular components, if present, restricted to the invasive front) were defined as the perihilar type, whereas the others were classified as peripheral cholangiocarcinomas. Among the 47 cases examined in the present study, 26 (55%) were classified as the perihilar type, whereas 21 (45%) were the peripheral type...

BACKGROUND: Although hemihepatectomy with total caudate lobectomy (hemiHx-tc) is essential for the surgical treatment of hilar cholangiocarcinoma, the advantage of an anterior approach for hemiHx-tc has not been fully discussed technically; the significance of an anterior approach without liver mobilization for preventing infectious complications also remains unknown. METHODS: The liver parenchyma transection-first approach (Hp-first) technique is an early transection of the hepatic parenchyma without mobilization of the liver that utilizes a modified liver-hanging maneuver to avoid damaging the future remnant liver...

Liver transplant is now an acceptable and effective treatment for specific nonhepatocellular malignancies. Worldwide, hilar cholangiocarcinoma accounts for 3% of all primary gastrointestinal malignancies and for 10% of primary hepatobiliary malignancies. For patients who have early-stage, unresectable cholangiocarcinoma, liver transplant preceded by neoadjuvant radiotherapy can result in tumor-free margins, accomplish a radical resection, and treat the underlying primary sclerosing cholangitis when present...

BACKGROUND: We present results of patients diagnosed with unresectable hilar cholangiocarcinomas treated with high dose radiotherapy and concurrent chemotherapy. METHODS: From Aug 2005 to Dec 2012, 68 consecutive patients were treated. Fifty patients (group 1) presenting to us with obstructive jaundice were planned for endobiliary brachytherapy (EBBT 14 Gy) followed external beam radiotherapy (EBRT 45 Gy). Twenty-two patients (group 2) who had previously undergone biliary drainage underwent EBRT (57 Gy)...

Patients with immunoglobulin (Ig) G4-related sclerosing cholangitis typically have a high serum IgG4 level. However, here we describe our experience of a patient with a normal serum IgG4 level for whom the cholangitis was diagnosed by liver biopsy. A 61-year-old male presented with elevated liver enzymes and a normal serum IgG4 level. The hilar, intrahepatic, and upper extrahepatic bile ducts were stenotic, with no evidence of a pancreatic lesion. We therefore performed a liver biopsy to differentiate between cholangiocarcinoma and primary sclerosing cholangitis...

BACKGROUND: IgG4-related sclerosing cholangitis (IgG4-SC) is the biliary manifestation of IgG4-related disease (IgG4-RD) but the presence of IgG4-SC in the porta hepatis is difficult to differentiate from hilar cholangiocarcinoma (HCCA). IgG4-related autoimmune hepatitis (IgG4-related AIH) is extremely rare and it is not fully clear whether IgG4-related AIH is a hepatic manifestation of IgG4-RD or a subtype of AIH. CASE PRESENTATION: We present a rare case of a 52-year-old male who was admitted with obstructive jaundice and itchy skin...
