Prognosis of resected intrahepatic cholangiocarcinoma

2017

Introduction. Complete resection stands as the only curative option for intrahepatic cholangiocarcinoma (IHCC). Still, prognosis remains poor after resection due to a recurrence rate over 60% leading to actual 5-year survival rates below 20%. Reliable prognostic estimation and better understanding of tumor biology would be of interest for improving IHCC prognosis.Methods. Using clinical and biological data from two large cohort of resected IHCC (MSKCC, n=189 and AFC, n=522), three objectives have been explored. First, assessing the performances of different published prognostic models. Second, defining the reliability of preoperative prognostic estimation using imaging, tumoral genomic prof…

Metallothionein overexpression and its prognostic relevance in intrahepatic cholangiocarcinoma and extrahepatic hilar cholangiocarcinoma (Klatskin tu…

2009

Metallothionein is a group of small molecular weight cysteine-rich proteins with a broad variety of functions. Metallothionein has been shown to regulate apoptosis and proliferation. Overexpression of metallothionein frequently occurs in human tumors and is related to prognosis as well as therapy response. However, metallothionein expression and its clinical relevance in cholangiocarcinoma have not been investigated. The present study aimed to analyze metallothionein over-expression and its possible prognostic impact in intrahepatic cholangiocarcinoma and hilar extrahepatic cholangiocarcinoma (Klatskin tumors). We investigated the relationship of immunohistochemically demonstrated metalloth…

Targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement: diagnostic value for differentiating HCC from other primary live…

2021

To evaluate targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement as potential new LI-RADS features for differentiating hepatocellular carcinoma (HCC) from other non-HCC primary liver carcinomas (PLCs). This IRB-approved, retrospective study was performed at two liver transplant centers. The final population included 375 patients with pathologically proven lesions imaged between 2007 and 2017 with contrast-enhanced CT or MRI. The cohort consisted of 165 intrahepatic cholangiocarcinomas and 74 combined hepatocellular-cholangiocarcinomas, with the addition of 136 HCCs for control. Two abdominal radiologists (R1; R2) independently reviewed the imaging studies (112…

Nonalcoholic fatty liver disease is associated with intrahepatic cholangiocarcinoma and not with extrahepatic form: definitive evidence from meta-ana…

2020

Background Cholangiocarcinoma is a cancer with poor prognosis. The detection of risk factors is fundamental to identify subjects at higher risk of cholangiocarcinoma. Nonalcoholic fatty liver disease (NAFLD) represents a leading cause of chronic liver disease worldwide. Recent data suggested that NAFLD increases the risk of cholangiocarcinoma development. However, it is necessary to better explain the strength of association between NAFLD and cholangiocarcinoma. Methods A systematic research of current case-control, cohort, clinical trial and meta-analysis on the main electronic databases was made. A recent systematic review was recognized. We performed cumulative meta-analyses with sensiti…

Liver transplantation as a primary indication for intrahepatic cholangiocarcinoma: a single-center experience.

2008

Abstract Background Intrahepatic cholangiocarcinoma (ICC) is not a widely accepted indication for orthotopic liver transplantation (OLT). The present study describes our institutional experience with patients who underwent transplantation for ICC as well as those with ICC who underwent transplantation with the incorrect diagnosis of hepatocellular carcinoma (HCC). Patients and Methods Data corresponding to ICC patients were reviewed for the purposes of this study. Patients with hilar cholangiocarcinoma and incidentally found ICC after OLT for benign diseases were excluded from further consideration. Results Among the 10 patients, 6 underwent transplantation before 1996 and 4 after 2001. Tho…

Guidelines for palliative surgery of cholangiocarcinoma

2008

AbstractThe aims of the guidelines are to help assess the evidence for palliation surgery in patients with cholangiocarcinoma (CCA). The guidelines are classified in accordance with the location of the primary lesion, i.e. intrahepatic, hilar, and distal. They are based on comprehensive literature surveys, including results from randomized controlled trials, systematic reviews and meta-analysis, and cohort, prospective, and retrospective studies. Intrahepatic CCA, i.e. resection of lymph-node-positive tumors and R1/R2 resections have not been shown to provide survival benefit: Evidence levels: 2b, 4; Recommendation grade C. Hilar CCA: R1 resection is justified as a very efficient palliation…

Influence of Lymphangio (L), Vascular (V), and Perineural (Pn) Invasion on Recurrence and Survival of Resected Intrahepatic Cholangiocarcinoma

2021

(1) Background: Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy. Besides tumor, nodal, and metastatic status, the UICC TNM classification describes further parameters such as lymphangio- (L0/L1), vascular (V0/V1/V2), and perineural invasion (Pn0/Pn1). The aim of this study was to analyze the influence of these parameters on recurrence and survival. (2) Methods: All surgical explorations for patients with ICC between January 2008 and June 2018 were collected and further analyzed in our institutional database. Statistical analyses focused on perineural, lymphangio-, and vascular invasion examined histologically and their influence on tumor recurrence and survival. (3) Results: Of 2…
