Abstract
Primary liver cancer is the sixth most common cancer worldwide with a wide geographic distribution. The incidence of primary liver cancer is increasing and there is still a higher prevalence in developing countries. Early recognition remains an obstacle and lack of it results in poor outcomes for hepatocellular carcinoma (HCC), the most prevalent primary liver cancer, and cholangiocarcinoma. The most common risk factors associated with HCC are hepatitis B and chronic hepatitis C infections, alcohol use, smoking, and aflatoxin exposure. Emerging risk factors such as obesity might play an important role in the future because of the increasing prevalence of this condition.

[PMID: 20922056 PMCID: PMC2948219 DOI: 10.7150/jca.1.141] [Citation(s) in RCA: 44] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2010] [Accepted: 10/01/2010] [Indexed: 02/07/2023] Open
Abstract
Background: Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) are the two most common primary liver cancers, yet there have been no significant advances in effective therapeutics. Mesothelin has been reported as a new therapeutic target in various types of cancer. Here, we investigated the expression of mesothelin in liver cancer and its potential role as a novel therapeutic target for immunotherapy. Methods: HCC and CCA specimens were examined by immunohistochemistry for mesothelin expression. Protein expression was assessed by immunoblotting and flow cytometry. The SS1P immunotoxin targeting mesothelin was evaluated in the well-established CCA cell lines HuCCT1, HuH-28, KMBC, KMCH, Mz-ChA-1 and OZ. Results: We showed strong immunochemical mesothelin staining in 33% of the surgically resected CCA specimens and 3 of 6 CCA cell lines (OZ, KMBC and KMCH). No mesothelin staining was found in HCC or normal liver tissue. Mesothelin was primarily localized to the cellular plasma membrane and the mature form (molecular weight, ~40 kDa) was expressed at a high level in CCA tissues. Moreover, 22% of CCA specimens had a high mesothelin expression level which was comparable to the CCA cell line models. Interestingly, SS1P showed very high and specific growth inhibition when added to mesothelin-expressing CCA cells with IC50 values ranging from 0.5 to 11 ng/mL. Conclusions: Mesothelin is overexpressed in one-third of CCA tissues. SS1P targeting mesothelin reveals a remarkable single agent activity against CCA in vitro. These findings indicate a potential for SS1P in the immunotherapeutic treatment of CCA.

Abstract
Background/Aims We aimed to evaluate survival time and prognostic factors in patients with advanced unresectable cholangiocarcinoma who have not received surgery, chemotherapy, or radiotherapy. Methods A total of 1,377 patients, who were diagnosed with primary cholangiocarcinoma between 1996 and 2002, were reviewed retrospectively according to the following inclusion criteria: histologically proven primary adenocarcinoma arising from the bile-duct epithelium, advanced unresectable stages, no severe comorbidity that can affect survival time, and no history of surgery, chemotherapy, or radiotherapy. Results Of the 1,377 cases reviewed, 330 patients complied with the inclusion criteria and were thus eligible to participate in this study; 203 had intrahepatic cholangiocarcinoma and 127 had hilar cholangiocarcinoma. The overall survival time of the entire cohort (n=330) was median 3.9 months (range; 0.2 to 67.1). The survival time was significantly shorter in the intrahepatic cholangiocarcinoma group (3.0±5.3 months) than in the hilar cholangiocarcinoma group (5.9±10.1 months; Kaplan-Meier survival analysis). Multivariate analysis revealed that distant metastasis was a poor prognostic factor for intrahepatic cholangiocarcinoma (p< 0.001), baseline serum albumin >3.0 g/dL was a favorable prognostic factor (p=0.02), and baseline serum carcinoembryonic antigen level >30 ng/mL was a poor prognostic factor for hilar cholangiocarcinoma (p=0.01). Conclusions The median survival of advanced unresectable cholangiocarcinoma is dismal.

Abstract
Intrahepatic cholangiocarcinoma is the second most common primary liver cancer behind hepatocellular cancer. Although it is an uncommon malignancy, several reports have documented a significant rise in incidence, not only in the United States, but worldwide over the last several decades. As a result, interest in understanding the presentation, diagnosis, natural history, and efficacy of various treatment modalities has increased. This article reviews the clinical presentation, preoperative work-up, surgical management, and outcomes of patients undergoing resection for intrahepatic cholangiocarcinoma. Treatment options in unresectable patients are also reviewed.

Abstract
Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare primary liver malignancy composed of cells with histopathological features of both cholangiocarcinoma (CC) and hepatocellular carcinoma (HCC). It reportedly accounts for 0.4-14.2% of all primary liver carcinomas, with incidence varying in different regions. The clinical features are similar to those of either HCC or CC. Preoperative noninvasive diagnosis of cHCC-CC with conventional radiography is difficult. Because the origin of cHCC-CC is from two different tumour entities, despite intensive preoperative imaging studies, most studied patients were misdiagnosed either as HCC or CC. Accurate preoperative diagnosis is important because the most appropriate treatment depends on the major component of the tumour (HCC or CC). A high index of suspicion, imaging studies (ultrasound, computed tomography, positron emission tomography), levels of serum tumour markers (alpha-fetoprotein, carbohydrate antigen 19-9), and histology assist case detection and treatment choice. Patients who qualify for surgery should have a partial hepatectomy with hilar lymph node dissection, which can result in 5-year survival rates exceeding 50%. The role of liver transplantation is not yet known.

Abstract
OBJECTIVE Mucin-producing cholangiocarcinoma (MPCC) is an uncommon biliary tract malignancy. This retrospective study was designed to investigate the clinical presentations, associated diseases, the value of tumor markers, and treatment and prognosis of MPCC. MATERIAL AND METHODS The study included 24 MPCC cases (7 M, 17 F) from 132 histopathology-proven cholangiocarcinoma patients seen between 1988 and 2003. MPCC and non-mucin-producing cholangiocarcinoma (non-MPCC) were compared. RESULTS Common clinical symptoms and signs included epigastric or right upper quadrant pain, fever and chills, jaundice, and anemia. Seventeen patients had mucobilia in surgical, cholangiographic, or CT findings. Biliary stones were found in 71% of MPCC patients. In detecting MPCC, a serum CA-19-9 level > 120 U/ml had 73% sensitivity, 41% specificity, 25% positive predictive value, 85% negative predictive value, and 48% accuracy in the 132 cholangiocarcinoma patients. The 1-, 2-, 3-, 4-, and 5-year survival rates were 44.3%, 33.8%, 28.1%, 21.1%, and 21.1%, respectively. Univariate analysis showed that tumor type (MPCC) was the only significant factor predicting survival when compared with non-MPCC patients in 5-year cumulative survival rates (21.1% versus 5.4%). MPCC patients receiving surgical resection had a prolonged median survival time (13 months versus 6 months) than those without resection. CONCLUSIONS MPCC clinical presentations were similar to non-MPCC in Taiwan except for more jaundice, fever and chills. The major factor predisposing to MPCC was biliary stones. Using serum CA19-9 levels greater than 120 U/ml was a diagnostic aid to detecting MPCC patients. MPCC patients had a better prognosis than non-MPCC patients. The recommended treatment for MPCC is surgical resection.

Abstract
AIM: The diagnosis of cholangiocarcinoma is often difficult, making management approaches problematic. A reliable serum marker for cholangiocarcinoma would be a useful diagnostic test. The aims of our study were to evaluate the usefulness of a serum CA19-9 determination in the diagnosis of cholangiocarcinoma.
METHODS: We prospectively measured serum CA19-9 and CEA concentrations in patients with cholangiocarcinoma (n = 35), benign biliary diseases (n = 92), and healthy individuals (n = 15). Serum CA19-9 and CEA concentrations were measured by an immunoradiometric assay without knowledge of the clinical diagnosis.
RESULTS: The sensitivity of a CA19-9 value > 37 KU·L-1 and a CEA value > 22 μg·L-1 in diagnosing cholangiocarcinoma were 77.14% and 68.57%, respectively. When compared with the benign biliary diseases group, the true negative rates of serum CA19-9 and CEA were 84.78% and 81.52%, respectively. The false positive rates of serum CA19-9 and CEA were 15.22% and 18.48%, whereas the accuracy of serum CA19-9 and CEA were 82.68% and 77.95%, respectively. Serum CA19-9 and CEA concentrations were significantly elevated (P < 0.001 and P < 0.05) in patients with cholangiocarcinoma (290.31 ± 5.34 KU·L-1 and 36.46 ± 18.03 μg·L-1) compared with patients with benign biliary diseases (13.38 ± 2.59 KU·L-1 and 13.84 ± 3.85 μg·L-1) and healthy individuals (12.78 ± 3.69 KU·L-1 and 11.48 ± 3.37 μg·L-1). In 15 patients undergoing curative resection of cholangiocarcinoma, the mean serum CA19-9 concentration was decreased from a preoperative level of 286.41 ± 4.36 KU·L-1 to a postoperative level of 62.01 ± 17.43 KU·L-1 (P < 0.001), and the mean serum CEA concentration from 39.41 ± 24.35 μg·L-1 to 28.69 ± 11.03 μg·L-1(P < 0.05). In patients with cholangiocarcinoma, however, no correlation was found between serum CEA and CA19-9 concentrations (r = 0.036).
CONCLUSION: These data suggest that the serum CA19-9 determination is a useful addition to the available tests for the differential diagnosis of cholangiocarcinoma. Serum CA19-9 is an effective tumor marker in diagnosing cholangiocarcinoma, deciding whether the tumor has been radically resected and monitoring effect of treatment.

Abstract
Using an electrochemiluminescence immunoassay, CYFRA 21-1 concentrations were measured in sera from 187 patients with primary liver cancer (164 with hepatocellular carcinoma (HCC) and 23 with intrahepatic cholangiocarcinoma (ICC)) and 87 patients with benign liver diseases. Concentrations of CYFRA 21-1 were significantly higher in patients with ICC (5.0; interquartile range 3.1-10.7 ng ml(-1)) than in those with benign liver disease (1.4; 1.0-1.9; Mann-Whitney U-test, P<0.0001) or HCC (1.7; 1.1-2.7; Mann-Whitney U-test, P<0.0001). Using cutoff values selected for 95% specificity in the benign group (3.0 ng ml(-1)), CYFRA 21-1 showed higher sensitivity for ICC (87.0%) than three commonly used markers including alpha-fetoprotein (17.4%), carcinoembryonic antigen (34.8%), and carbohydrate antigen 19-9 (60.9%). Serum CYFRA 21-1 increased in ICC from stages I/II to IV (Kruskal-Wallis test, P=0.0102). CYFRA 21-1 concentration increased with extent of local invasion, but not nodal status. Serum CYFRA 21-1 represents a useful diagnostic test for ICC that offers high sensitivity. CYFRA 21-1 reflected differences in tumour burden, suggesting applicability to staging and follow-up.

Abstract
Cholangiocarcinoma (CC), a malignant neoplasm of the biliary epithelium, is usually fatal because of difficulty in early diagnosis and lack of availability of effective therapy. Furthermore, little is known about the genetics and biology of CC. Only a few reports concerning cytogenetic studies of CC have been published, and few cell lines have been established. We recently established four CC cell lines, designated as SCK, JCK, Cho-CK, and Choi-CK, and report the first application of cross-species color banding (RxFISH) and multiple chromosome painting for the characterization of the chromosomal rearrangements of these CC cell lines. Each cell line had unique modal karyotypic characteristics and showed a variable number of numerical and structural clonal cytogenetic aberrations. Chromosomes 3, 6, 7, 8, 12, 14, 17, and 18 were commonly involved in structural abnormalities. Homogeneously staining regions were determined in SCK and JCK, and double minute chromosomes were found in Cho-CK. The chromosomal aberrations of the four CC cell lines were effectively analyzed by RxFISH and FISH with multiple chromosome painting probes. The nonrandom rearrangements suggest candidate regions for isolation of genes related to CC.

Abstract
Expression of MET, the c-met-encoded receptor for hepatocyte growth factor, has not been investigated in proliferative biliary diseases of human liver, including hepatolithiasis and cholangiocarcinoma. Comparatively, we analyzed by immunohistochemistry the expression of MET in normal adult human livers (n = 20), normal postnatal preadult livers (n = 21), fetal livers (n = 36), hepatolithiatic livers (n = 32), and intrahepatic cholangiocarcinomas (n = 26). In normal adult livers, obvious MET immunoreactivity was not found in any cell types. In fetal liver, MET was weakly expressed in primitive biliary cells (ductal plate and immature bile ducts) and immature hepatocytes during 8 to 30 gestational weeks but was essentially negative thereafter. In hepatolithiasis, a condition of risk for cholangiocarcinoma development, MET was overexpressed in proliferated biliary cells in 26 of 32 cases (81%). In this nonneoplastic proliferative biliary condition, MET immunoreactivity was observed to be most prominent in the hyperplastic septal and large bile ducts of liver, and in the proliferated peribiliary glands associated with intrahepatic large bile ducts. In intrahepatic cholangiocarcinoma, MET overexpression in neoplastic biliary epithelium was observed in 15 of 26 cases (58%) and correlated with the degree of tumor differentiation, being highest in well-differentiated tumors and relatively low in poorly differentiated tumors. These data show for the first time that overexpression of MET is a common feature of hyperplastic and neoplastic biliary epithelial cells in human liver and suggest that MET/hepatocyte growth factor may be playing an important role in human biliary hyperplasia and in cholangiocarcinogenesis in vivo.
