Abstract
Overexpression of casein kinase 2 (CK2) has an oncogenic and pro-survival role in many cancers. CX-4945 (Silmitasertib) is a CK2 inhibitor with anti-cancerous and anti-angiogenic effects. Up to date, the anti-cancer effect and mechanism of CX-4945 on human cholangiocarcinoma (CCA) remain unclear. This study investigated whether CX-4945 inhibits growth and induces apoptosis of HuCCT-1 cells, a human CCA cell line. Of note, treatment with CX-4945 at 20 μM markedly reduced survival and induced apoptosis of HuCCT-1 cells, as evidenced by nuclear DNA fragmentation, PARP cleavage, activation of caspase-9/3, and up-regulation of DR-4. Although CX-4945 did not affect the phosphorylation and expression of CK2, it vastly inhibited the phosphorylation of CK2 substrates, supporting the drug's efficacy in inhibiting CK2 and its downstream pathway. Importantly, knockdown of CK2 that partially suppressed the phosphorylation of CK2 substrates resulted in a significant reduction of HuCCT-1 cell survival. In addition, CX-4945 reduced the phosphorylation and expression of STAT-3 and STAT-5 in HuCCT-1 cells, and pharmacological inhibition or respective knockdown of these proteins resulted in significant growth suppression of HuCCT-1 cells. CX-4945 also had abilities to decrease Mcl-1 expression while increasing eIF-2α phosphorylation in HuCCT-1 cells. Furthermore, there was a time-differential negative regulation of HIF-1α expression by CX-4945 in HuCCT-1 cells, and knockdown of HIF-1α caused a significant reduction of the cell survival. In summary, these results demonstrated that CX-4945 has anti-growth, anti-angiogenic, and pro-apoptotic effects on HuCCT-1 cells, which are mediated through control of CK2, caspase-9/3, DR-4, STAT-3/5, Mcl-1, eIF-2α, and HIF-1α.

Medicine (Baltimore) 2021; 100:e27349. [PMID: 34797273 PMCID: PMC8601323 DOI: 10.1097/md.0000000000027349] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Accepted: 09/09/2021] [Indexed: 01/05/2023] Open
Abstract
RATIONALE Presence of synchronous double hepatocelluar carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) (sdpHCC-ICC) located separately within a single liver is extremely rare. The purpose of this study is to investigate the clinical, imaging, pathological characteristics, and prognosis of patients with sdpHCC-ICC, in order to enhance our understanding of the disease and improve diagnostic and therapeutic effect. PATIENT CONCERNS A 49-year-old, female with the diagnosis of hepatitis B virus with obvious liver cirrhosis, was admitted to our hospital. On admission, the levels of α-fetoprotein and carbohydrate antigen 19-9 were found to be elevated. Abdominal ultrasonography and enhanced computed tomography revealed 2 solid masses located in segments (S) 4 and 6 of the liver, with malignant behaviors. DIAGNOSES In the light of above investigations, preoperative diagnosis of multiple primary hepatocellular carcinomas was made. INTERVENTION Hepatic resection of both segments was done. The resected specimens revealed the presence of well-defined tumors in segments 4 and 6 measuring 5.0 cm and 2.5 cm respectively. OUTCOMES Histopathological examination confirmed the tumor of the 4th segment to be moderately and poorly differentiated ICC, and the tumor of the 6th segment to be poorly differentiated HCC. Immunohistochemically, the ICC in S4 was positive for CK19 and negative for Heppar-1, whereas the HCC in S6 was positive for Heppar-1 and negative for CK19. Unfortunately, metastasis to multiple organs and lymph nodes were observed 3 months later. The patient died of liver failure 16 months after surgery. LESSONS The clinical characteristics of sdpHCC-ICC are usually atypical and nonspecific making its preoperative diagnosis quite difficult. Hepatitis B virus and hepatitis C virus infection were both the independent risk factor for the development of sdpHCC-ICC. In patients with chronic liver disease, careful observation with imaging is of utmost necessity. Tumor markers may also play a valuable role in the diagnosis. The definite diagnosis depends on pathological examination. Hepatic resection is considered the most effective mode of treatment. The prognosis of synchronous occurrence of double hepatic cancers is worse than either HCC or ICC, and the origin of the disease needs further study.

Abstract
The performance of data-independent acquisition (DIA) mass spectrometry (MS) depends on the separation efficiency of peptide precursors. In Orbitrap-based mass spectrometers, separation efficiency of peptide precursors is limited by the relatively slow scanning rate compared to time of flight (TOF)-based MS. Here, we present PulseDIA, a multi-injection gas-phase fractionation (GPF) strategy for enhanced DIA-MS. This is achieved by equally dividing the conventional DIA analysis covering the entire mass range into multiple injections for DIA analyses with complementary windows. Using mouse liver digests, the PulseDIA method identified up to 50% more peptides and 29% more protein groups than that by conventional DIA with the same length of effective gradient time. Compared to conventional multi-injection GPF, PusleDIA exhibited higher flexibility and identified up to 18% more peptides and 8% more protein groups using two injections. The gain of peptides per effective time unit was the highest in PulseDIA compared to conventional DIA and GPF. We further applied the PulseDIA method to profile the proteome of 18 human tissue samples (benign and malignant) from nine cholangiocarcinoma (CCA) patients. PulseDIA identified 7796 protein groups in these CCA samples, with a 14% increase of protein group identification compared to the conventional DIA method. The missing value for protein matrix dropped by 7% using PulseDIA compared to DIA. A total of 681 significantly altered proteins were detected in CCA samples using PulseDIA, including several dysregulated proteins, which were absent in the conventional DIA analysis. Taken together, we present PulseDIA as an enhanced DIA-MS method with improved sensitivity and reproducibility.

Abstract
BACKGROUNDS We aimed to investigate the diagnostic accuracy of multidetector-row computed tomography (MDCT), mapping biopsy, and other imaging modalities to predict the longitudinal extension and depth of invasion of extrahepatic cholangiocarcinoma at possible surgical ductal margins. METHODS Of 102 patients with surgical resection of extrahepatic cholangiocarcinoma between January 2010 and October 2015, 32 evaluated by multidetector-row computed tomography (MDCT) performed before biliary drainage and mapping biopsy were enrolled. Mapping biopsies were performed at 74 sites to determine the resection point of the bile duct (at 74 possible surgical ductal margins). Diagnostic accuracy was evaluated by histopathology. RESULTS The diagnostic accuracy of MDCT for longitudinal cancer spread was 79.7%, that of biopsy was 73.0%, and combining the two modalities showed highest accuracy (83.8%). The depth of tumor invasion could be predicted by combination of the ductal wall thickness and contrast enhancement on MDCT, that is, at 11 of 13 sites (84.6%) with submucosal invasion, ductal wall thickness was > 2.5 mm with high contrast enhancement. CONCLUSIONS MDCT demonstrated highest accuracy of diagnosing longitudinal extension at possible surgical ductal margins in patients with extrahepatic cholangiocarcinoma. The depth of tumor invasion could be predicted by ductal wall thickness and contrast enhancement of MDCT.

Abstract
The overall survival (OS) rate of extrahepatic cholangiocarcinoma (ECC) remains much lower than that for other gastrointestinal malignancies. A variety of factors have been used to predict prognosis after surgical resection for ECC, but no consensus has been reached. Therefore, this study sought to identify useful prognostic factors for patients with ECC. In our institution, within the study period, 76 patients received surgical resection for mid to distal cholangiocarcinoma. Clinicopathological data were retrospectively collected, along with survival and prognosis. In multi-variate analysis for OS, ductal margin status (P = 0.008) and pT category (P < 0.02) presented independent predictors of survival. In the R0 resection group, N stage and adjuvant chemotherapy presented independent predictors of recurrence in the multivariate model. The three- and five-year survival rates were significantly better in patients with negative ductal margins (77.% at three years and 63.6% at five years) than in those with positive ductal margins (33.3% at three years and 25.0% at five years) (P < 0.05). Survival rates were similar between cases of R0 resection without gemcitabine-based chemotherapy and R1 resection with gemcitabine-based chemotherapy (P = 0.6193, Log-rank test). However, survival rates between R0 resection with gemcitabine-based chemotherapy and R1 resection with gemcitabine-based chemotherapy were significantly different (P = 0.0086, Log-rank test). For good prognosis, radical resection to ensure adequate margin may be recommended for middle common bile duct cancer. In addition, regardless of margin negativity, gemcitabine-based chemotherapy is recommended for prolongation of relapse-free time and OS time.

Abstract
Chimeric antigen receptor modified T cell-based immunotherapy is revolutionizing the field of cancer treatment. However, its potential in treating bile duct carcinoma has not been fully explored. Herein, we developed the second-generation mesothelin-targeting chimeric antigen receptor-modified T cells with the 4-1BB co-stimulatory module by the piggyBac transposon system. Mesothelin-targeting chimeric antigen receptor was expressed by 66.0% of mesothelin-targeting chimeric antigen receptor-modified T cells post electrophoretic transfection and stimulation with K562-meso cells; the expressions of activation markers were tested by flow cytometry assay and showed greater activation of mesothelin-targeting chimeric antigen receptor-modified T cells than control T cells (CD107α: 71.9% vs 48.6%; CD27: 92.1% vs 61.8%; CD137: 55.5% vs 8.4%; CD28: 98.0% vs 82.1%; CD134: 37.5% vs 10.4%). Furthermore, mesothelin-targeting chimeric antigen receptor-modified T cells exerted cytotoxicity toward mesothelin-expressing EH-CA1b and EH-CA1a cells in an effector-to-target ratio-dependent manner, while leaving mesothelin-negative GSC-SD and EH-GB1 cells and normal liver L02 cells almost unharmed. Mesothelin-targeting chimeric antigen receptor-modified T cells secreted cytokines at higher levels when co-cultured with mesothelin-positive EH-CA1a and EH-CA1b cells than with mesothelin-negative GSC-SD and EH-GB1 cells. Enhanced cytotoxicity and cytokine secretion of mesothelin-targeting chimeric antigen receptor-modified T cells compared to control T cells were also observed when co-cultured with 293-meso cells (interferon γ: 85.1% ± 1.47% vs 8.3% ± 2.50%, p = 0.000; tumor necrosis factor α: 90.9% ± 4.67% vs 18.5% ± 3.62%, p = 0.0004; interleukin 2: 60.8% ± 2.00% vs 15.6% ± 2.06%, p = 0.002; interleukin 6: 6.4% ± 2.95% vs 1.7% ± 0.63%, p = 0.055). In addition, mesothelin-targeting chimeric antigen receptor-modified T cells showed greater inhibitory and proliferative capability than control T cells within EH-CA1a cell xenografts. This study shows the potential of mesothelin-targeting chimeric antigen receptor-modified T cells in treating bile duct carcinoma.

Double primary hepatic cancer (hepatocellular carcinoma and intrahepatic cholangiocarcinoma) originating from hepatic progenitor cell: a case report and review of the literature.

Abstract
BACKGROUND Synchronous development of primary hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) in different sites of the liver have rarely been reported before. The purpose of this study is to investigate the clinicopathological characteristics of synchronous double cancer of HCC and ICC. CASE PRESENTATION A 56-year-old Chinese man without obvious liver cirrhosis was preoperation diagnosed with multiple HCC in segments VI (SVI) and VII (SVII) by the abdominal computed tomography (CT) and contrast-enhanced ultrasonography (CEUS). We performed hepatic resection of both segments. The tumors in SVI and SVII were pathologically diagnosed as ICC and HCC, respectively. Immunohistochemically, the HCC in SVII was positive for HepPar-1 and negative for CK19, while the ICC in SVI tumor was positive for CK19 and negative for HepPar-1. Interestingly, the immunohistochemical results also showed that the classic hepatic progenitor cell (HPCs) markers CD34 and CD117 were both positive of the two tumors. The patient still survived and at a 1-year follow-up did not show evidence of metastasis or new recurrent lesions. We speculate that the two masses may have originated from HPCs based on the findings of this patient. CONCLUSIONS Synchronous development of HCC and ICC is very rare with unique clinical and pathological features. The correct preoperative diagnosis of double hepatic cancer of HCC and ICC is difficult. Hepatitis B virus (HBV) and hepatitis C virus (HCV) infection were both the independent risk factor to the development of double liver cancer. Hepatic resection is the preferred and most effective treatment choice. The prognosis of synchronous occurrence of double hepatic cancer was poorer than for either HCC or ICC, and the origin of it needs further study.

Co‑expression of the carbamoyl‑phosphate synthase 1 gene and its long non‑coding RNA correlates with poor prognosis of patients with intrahepatic cholangiocarcinoma. Mol Med Rep 2015; 12:7915-26. [PMID: 26499888 PMCID: PMC4758274 DOI: 10.3892/mmr.2015.4435] [Citation(s) in RCA: 38] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2015] [Accepted: 09/01/2015] [Indexed: 12/25/2022] Open
Abstract
The mechanisms leading to high rates of malignancy and recurrence of human intrahepatic cholangiocarcinoma (ICC) remain unclear. It is difficult to diagnose and assess the prognosis of patients with ICC in the clinic due to the lack of specific biomarkers. In addition, long non-coding RNAs (lncRNAs) have been reported to serve important roles in certain types of tumorigenesis however a role in ICC remains to be reported. The aim of the current study was to screen for genes and lncRNAs that are abnormally expressed in ICC and to investigate their biological and clinicopathological significance in ICC. The global gene and lncRNA expression profiles in ICC were measured using bioinformatics analysis. Carbamoyl-phosphate synthase 1 (CPS1) and its lncRNA CPS1 intronic transcript 1 (CPS1-IT1) were observed to be upregulated in ICC. The expression of CPS1 and CPS1-IT1 was measured in 31 tissue samples from patients with ICC and a number of cell lines. The effects of CPS1 and CPS1-IT1 on the proliferation and apoptosis of the ICC-9810 cell line were measured. In addition, the clinicopathological features and survival rates of patients with ICC with respect to the gene and lncRNA expression status were analyzed. CPS1 and CPS1-IT1 were co-upregulated in ICC tissues compared with non-cancerous tissues. Knockdown of CPS1 andor CPS1-IT1 reduced the proliferation and increased the apoptosis of ICC-9810 cells. Additionally, clinical analysis indicated that CPS1 and CPS1-IT1 were associated with poor liver function and reduced survival rates when the relative expression values were greater than 4 in cancer tissues. The comparisons between the high CPS1 expression group and the low expression group indicated significant differences in international normalized ratio (P=0.048), total protein (P=0.049), indirect bilirubin (P=0.025), alkaline phosphatase (P=0.003) and disease-free survival (P=0.034). In addition, there were differential trends in CA19-9 (P=0.068), globulin (P=0.052) and total bilirubin (P=0.066). The comparisons between the high CPS1-IT1 expression group and the low expression group indicated significant differences in lymphatic invasion (P=0.045), carbohydrate antigen 19-9 (P=0.044), disease-free survival (P=0.026), and non-significant differential trends in alkaline phosphatase were observed (P=0.085). In conclusion, CPS1 and CPS1-IT1 may serve an important role in ICC development by promoting the proliferation of ICC cells. Furthermore, CPS1 and CPS1-IT1 were associated with poor liver function and reduced survival rates. Thus, CPS1 and CPS1-IT1 may be potential prognostic indicators for patients with ICC.

Survival outcomes and progonostic factors of extrahepatic cholangiocarcinoma patients following surgical resection: Adjuvant therapy is a favorable prognostic factor.

Abstract
This study was conducted to investigate survival and prognostic factors for extrahepatic cholangiocarcinoma (ECC) following surgical resection and evaluate the effects of postoperative adjuvant therapy (AT) on overall survival (OS). We retrospectively collected clinical and pathological data between March, 2008 and December, 2013. The Kaplan-Meier method and the COX regression model were used to evaluate the OS and prognostic factors of 105 postoperative ECC patients, of whom 32 had received AT. The patients were stratified into seven risk subgroups and the survival rates were compared within each subgroup between patients who received AT and those who did not. The results demonstrated a median OS of 17.6 months, with 1- and 3-year survival rates of 67.9 and 19.5%, respectively, for the entire cohort. On univariate analysis, preoperative cholangitis, non-R0 surgical margins, poor differentiation grade, stage 3/4 and lymphatic metastasis were identified as adverse prognostic factors. AT was not significantly associated with improved OS. However, the subgroup analysis revealed that the effect of AT was significant only in the lymphatic metastasis group (median OS, 21.6 vs. 10.4 months; and 3-year OS, 16.6 vs. 0%, respectively; P=0.02). The survival curves of the AT and non-AT groups were significantly different only for node-positive patients. The COX regression model identified lymphatic metastasis, surgical margins and AT as independent prognostic factors for ECC. A negative resection margin may reduce the mortality rate following surgery by 47%. By contrast, lymph node metastasis was associated with a 2.18-fold higher mortality rate for ECC patients. Postoperative AT contributed to a 0.45-fold mortality rate compared to non-AT ECC patients. Therefore, we concluded that AT is a favorable prognostic factor for ECC patients and it may prolong the survival of patients with lymphatic metastasis. Our data suggest that postoperative AT should be recommended for node-positive ECC patients.

Abstract
Cholangiocarcinoma (CCA), or tumor of the biliary tree, is a rare and heterogeneous group of malignancies associated with a very poor prognosis. Depending on their localization along the biliary tree, CCAs are classified as intrahepatic, perihilar, and distal, and these subtypes are now considered different entities that differ in tumor biology, the staging system, management, and prognosis. When diagnosed, an evaluation by a multidisciplinary team is essential; the team must decide on the best therapeutic option. Surgical resection of tumors with negative margins is the best option for all subtypes of CCA, although this is only achieved in less than 50% of cases. Five-year survival rates have increased in the recent past owing to improvements in imaging techniques, which permits resectability to be predicted more accurately, and in surgery. Chemotherapy and radiotherapy are relatively ineffective in treating nonoperable tumors and the resistance of CCA to these therapies is a major problem. Although the combination of gemcitabine plus platinum derivatives is the pharmacological treatment most widely used, to date there is no standard chemotherapy, and new combinations with targeted drugs are currently being tested in ongoing clinical trials. This review summarizes the biology, clinical management, and pharmacological perspectives of these complex tumors.

Abstract
microRNAs (miRs) play an important role in tumor initiation and progression in many types of cancer, including cholangiocarcinoma (CC). miR-138 dysregulation is frequently observed in a variety of tumors. In the present study, miR-138 was found to be downregulated in CC tissues by quantitative real-time RT-PCR. Furthermore, its potential target molecule, Ras homolog gene family, member C (RhoC) protein, was found to be highly expressed in CC tissues examined by western blot analysis. Luciferase reporter assay further demonstrated that miR-138 directly targeted RhoC. We found that the introduction of miR-138 mimics to RBE and QBC939 CC cells could reduced RhoC mRNA and protein expression, and suppressed the proliferation, G1/S transition, migration and invasion of CC cells. However, transfection with a miR-138 inhibitor induced an inverse effect in CC cells. The expression of phosphorylated extracellular signal-regulated kinase (p-ERK), matrix metalloproteinase (MMP)-2 and MMP-9 decreased following transfection with miR-138, and increased following transfection with miR-138 inhibitor in CC cells. In conclusion, RhoC upregulation induced by miR-138 downregulation promotes the malignant progression of CC cells and the underlying mechanisms of this effect involve the increase in the expression of p-ERK/MMP-2/MMP-9. Consequently, miR-138/RhoC is a potential target for the clinical diagnosis and treatment of CC.

Abstract
Cholangiocarcinoma is the second most common primary hepatobiliary malignancy after hepatocellular carcinoma and remains among the most difficult management problems faced by surgeons. Curative surgery is achieved in only 25% to 30% of patients. Local tumor extent, such as portal vein invasion and hepatic lobar atrophy, does not preclude resection. Long-term survival has been seen only in patients who underwent extensive liver resections, suggesting that bile-duct excision alone is less effective. The majority of patients have unresectable disease, with 20% to 30% incidence of distant metastasis at presentation. Unresectable patients should be referred for nonsurgical biliary decompression, and in potential curative resection candidates the use of biliary stents should be reduced. Liver transplantation provides the option of wide resection margins, expanding the indication of surgical intervention for selected patients who otherwise are not surgical candidates due to lack of functional hepatic reserve.

Abstract
AKT1 signaling pathway is important for the regulation of protein synthesis and cell survival with implications in carcinogenesis. In this study, we explored the prognostic significance of AKT1 pathway in intrahepatic cholangiocarcinomas. We investigated the status of phosphatase and tensin homolog deleted on chromosome 10 (PTEN), phosphorylated (p) AKT1 (p-AKT1), p-mammalian target of rapamycin (p-MTOR), p-p70 ribosomal protein S6 kinase (p-RPS6KB2) and p-eukaryotic initiation factor 4E-binding protein-1 (p-EIF4EBP1) in 101 intrahepatic cholangiocarcinomas by immunohistochemistry. Western blot analysis was performed to verify the expression levels of p-AKT1 and p-MTOR. The relationship of protein expression with clinicopathological data and the correlations of protein expression levels were explored. The overexpression of p-AKT1, p-MTOR, and PTEN was associated with a better survival in patients with intrahepatic cholangiocarcinoma (P=0.0137, 0.0194, and 0.0337, respectively). In a multivariate analysis, PTEN was an independent prognostic factor, and p-AKT1 showed tendency (P=0.032 and 0.051, respectively). The overexpression of p-MTOR was correlated with well-to-moderately differentiated tumors (P<0.001) and tumors without metastasis (P=0.046). Expression levels of the AKT1 signaling pathway proteins in this study showed positive correlations with each other, except for PTEN. Aberrant expressions of p-AKT1 and p-MTOR in intrahepatic cholangiocarcinoma were associated with a favorable prognosis, possibly in a PTEN-independent manner. Our results indicate that dysregulation of the AKT1 pathway may have an important role in the development of intrahepatic cholangiocarcinoma, but not necessarily in the progression of the disease.

Abstract
The aim of the study was to evaluate the effectiveness of transarterial chemoembolization (TACE) with four chemotherapeutic protocols in terms of local tumor control and survival of patients with unresectable cholangiocarcinoma (CCC) and to identify the prognostic factors governing treatment success. In the single-centre study, 115 patients (mean ages = 60.4 years) with unresectable CCC were repeatedly treated with TACE. In total, 819 chemoembolization sessions were performed in 4 week intervals with a mean of 7.1 (range, 3-30) sessions per patient. The chemotherapeutic used was Mitomycin C only in 20.9% of patients, Gemcitabine only in 7%, Mitomycin C with Gemcitabine in 47% and combination of Gemcitabine, Mitomycin C and Cisplatin in 25.1%. Local tumor response was evaluated by MRI according to RECIST. Survival data were calculated according to the Kaplan-Meier method. Prognostic factors for patient's survival were evaluated using log-rank-test. The local tumor controls were: partial response 8.7%, stable disease 57.4% and progressive disease 33.9% of patients. The median and mean survival times from the start of TACE were 13 and 20.8 months. Survival rate from the start of TACE was 52% after 1-year, 29% after 2-years and 10% after 3-years. Initial tumor response, high tumor vascularity and Child-Pugh class A were statistically significant factors for patient's survival. No statistically significant difference between patients treated with different chemotherapy protocols was noted. In conclusion, TACE is a palliative and safe treatment option for patients with unresectable CCC. Child Pugh class B, tumor hypovascularity and initially progressive disease were poor prognostic factors for patient survival.

Abstract
Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare form of primary liver cancer composed of cells with histopathologic features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). Because of its low incidence, the information on clinical outcomes of cHCC-CC is very limited and there are no published reports describing non-surgical treatment options for cHCC-CC. We report a case of cHCC-CC exhibiting a favorable response to systemic chemotherapy with doxorubicin and cisplatin. A 62-year-old man who recurred after a right lobectomy for cHCC-CC received sorafenib for palliative systemic therapy, but follow up imaging studies showed disease progression. He received 2nd line chemotherapy with doxorubicin at 60 mg/m2 together with cisplatin at 70 mg/m2. After 2 cycles of chemotherapy, a computed tomography scan of the chest showed markedly decreased size and number of the multiple lung metastases. After completing 8 cycles of 2nd line therapy, we changed the regimen to a fluorouracil (5-FU) mono therapy because of the toxicities associated with doxorubicin and cisplatin. To date, the patient has completed his 15th cycle of 5-FU mono therapy with the disease status remaining stable during 18 months of follow-up.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (IHC) is a rare liver malignancy with a rising incidence worldwide. Since no standard treatment has been established so far, the aim of this study was to assess the safety and efficacy of repeated liver resection and/or radiofrequency ablation (RFA) in selected cases with recurrent IHC. PATIENTS AND METHODS The outcome of 13 patients who had been treated at least once for recurrent IHC by repeated liver resection and/or RFA was retrospectively analyzed. A total of 12 repeated liver resections and 8 radiofrequency ablations were performed in these patients between 2002 and 2008. RESULTS After a median follow-up period of 28 months after primary liver resection (12-69 months), seven patients (54%) are still alive and three of these patients (23% of the entire cohort) are regarded as disease-free. The median survival for all patients was 51 months (12-69 months). One- and three-year survival after primary surgery was 92 and 52%, respectively, with an overall complication rate of 7.6%. CONCLUSION According to the present data, repeated liver resection and radiofrequency ablation are feasible in select patients with recurrent IHC. Both procedures can be regarded as safe and might lead to a prolongation of patient survival.

Abstract
BACKGROUND/AIMS This study was conducted to analyze the prognostic factors in patients with intrahepatic cholangiocarcinoma (ICC) who did not receive surgery. METHODS Between August 1997 and November 2007, the medical records of 175 patients (mean age; 66 years, male/female 126/49), who were diagnosed as ICC, were reviewed retrospectively. RESULTS Clonorchiasis and hepatolithiasis was found in 14.9%, and 6.3% of all patients, and no risk factors were identified in 77.8% of them. Surgical resection was performed in 29.1% (51 patients), chemotherapy +/- radiotherapy in 12.6% (22 patients), and palliative therapy in 58.3% (102 patients). The proportion of patients with stage I was 23.4% (41 patients). The prognostic factors in patients who did not receive surgery were alkaline phosphatase (ALP) and bilirubin levels by univariate and multivariate analysis. The median survival of patients with normal ALP and bilirubin levels was six months, whereas only one month in patients with elevated ALP and bilirubin levels (p<0.001). Tumor characteristics of patients with elevated bilirubin and ALP levels were infiltrative tumor, bile duct involvement, and very huge tumor. CONCLUSIONS The prognostic factors of ICC in patients who did not receive surgery were ALP and bilirubin levels, but not lymph node metastasis.

Abstract
Several advances in diagnosis, treatment and palliation of cholangiocarcinoma (CC) have occurred in the last decades. A multidisciplinary approach to this disease is therefore recommended. CC is a relatively rare tumor and the main risk factors are: chronic inflammation, genetic predisposition and congenital abnormalities of the biliary tree. While the incidence of intra-hepatic CC is increasing, the incidence of extra-hepatic CC is trending down. The only curative treatment for CC is surgical resection with negative margins. Liver transplantation has been proposed only for selected patients with hilar CC that cannot be resected who have no metastatic disease after a period of neoadjuvant chemo-radiation therapy. Magnetic resonance imaging/magnetic resonance cholangiopancreatography, positron emission tomography scan, endoscopic ultrasound and computed tomography scans are the most frequently used modalities for diagnosis and tumor staging. Adjuvant therapy, palliative chemotherapy and radiotherapy have been relatively ineffective for inoperable CC. For most of these patients biliary stenting provides effective palliation. Photodynamic therapy is an emerging palliative treatment that seems to provide pain relief, improve biliary patency and increase survival. The clinical utility of other emerging therapies such as transarterial chemoembolization, hepatic arterial chemoinfusion and high intensity intraductal ultrasound needs further study.

Abstract
BACKGROUND/AIMS Multiple genes have been implicated in cholangiocellular carcinoma (CCC) development. However, the overall neoplastic risk is likely associated with a much lower number of critical physiological pathways. METHODS To investigate this hypothesis, we extracted all published genetic associations for the development of CCC from PubMed (genetic association studies, but also studies associating genes and CCC in general, i.e. functional studies in cell lines, genetic studies in humans, knockout mice etc.) and integrated CCC microarray data. RESULTS We demonstrated the MAPK pathway was consistently enriched in CCC. Comparing our data to genetic associations in HCC often successfully treated by a multityrosine kinase inhibitor, sorafenib, we demonstrated a similar overrepresentation of MAPK. In contrast, most cancer-related genetic studies focusing on genes related to transcription and cell cycle control, we consistently found genes coding for products in the extracellular environment to be significantly enriched. Thus, CCC must be regarded as developing in the context of an altered extracellular environment. CONCLUSIONS Our study suggests the liver microenvironment holds essential functions and structures key to CCC progression. Furthermore, we identified the MAPK signaling pathway consistently enriched, pointing towards a critical role in CCC development. These data may provide a rationale for treatment of CCC with sorafenib.

Abstract
PURPOSE To evaluate the response to lapatinib, an inhibitor of epidermal growth factor receptors 1 and 2, in patients with advanced bilary tree cancer (BTC) and hepatocellular cancer (HCC). METHODS Lapatinib was dosed at 1,500 mg/day orally continuously. RESULTS Fifty-seven patients were accrued (BTC 17, HCC 40). Therapy was well tolerated. The response in BTC was 0% and in HCC was 5%. The progression free survival (PFS) for BTC and HCC patients was 1.8 (95% CI: 1.7-5.2) months and 2.3 (95% CI: 1.7-5.6) months. The median survival for BTC and HCC patients was 5.2 (95% CI 3.3-infinity) months and 6.2 (95% CI: 5.1-infinity) months. EGFR genotyping indicated HCC patients with <20 repeats have the lowest PFS. The occurrence of any skin rash significantly prolonged PFS and survival. CONCLUSIONS Lapatinib was well-tolerated. There was evidence of activity in HCC, but therapy with lapatinib did not meet the predefined efficacy rate.

Sirica AE. Role of ErbB family receptor tyrosine kinases in intrahepatic cholangiocarcinoma. World J Gastroenterol 2008; 14:7033-58.

Abstract
Aberrant expression and signaling of epidermal growth factor receptor (ErbB) family receptor tyrosine kinases, most notably that of ErbB2 and ErbB1, have been implicated in the molecular pathogenesis of intrahepatic cholangiocarcinoma. Constitutive overexpression of ErbB2 and/or ErbB1 in malignant cholangiocytes has raised interest in the possibility that agents which selectively target these receptors could potentially be effective in cholangiocarcinoma therapy. However, current experience with such ErbB-directed therapies have at best produced only modest responses in patients with biliary tract cancers. This review provides a comprehensive and critical analysis of both preclinical and clinical studies aimed at assessing the role of altered ErbB2 and/or ErbB1 expression, genetic modifications, and dysregulated signaling on cholangiocarcinoma development and progression. Specific limitations in experimental approaches that have been used to assess human cholangiocarcinoma specimens for ErbB2 and/or ErbB1 overexpression and gene amplification are discussed. In addition, current rodent models of intrahepatic cholangiocarcinogenesis associated with constitutive ErbB2 overexpression are reviewed. Select interactive relationships between ErbB2 or ErbB1 with other relevant molecular signaling pathways associated with intrahepatic cholangiocarcinoma development and progression are also detailed, including those linking ErbB receptors to bile acid, cyclooxygenase-2, interleukin-6/gp130, transmembrane mucins, hepatocyte growth factor/Met, and vascular endothelial growth factor signaling. Lastly, various factors that can limit therapeutic efficacy of ErbB-targeted agents against cholangiocarcinoma are considered.

Abstract
UNLABELLED Cholangiolocellular carcinoma (CLC), a subtype of cholangiocellular carcinoma (CC), is thought to originate from the ductules/canals of Hering, where hepatic progenitor cells (HPCs) are located. We investigated the clinicopathological features of 30 CLCs and their relationship to HPCs. We evaluated the expression of hepatocytic markers (hepatocyte paraffin-1, canalicular polyclonal carcinoembryonic antigen, and CD10), biliary/HPC markers (keratin [K]7, K19, and neural cell adhesion molecule), the adenosine triphosphate binding cassette transporters: multidrug resistance protein 1, multidrug resistance-associated protein (MRP)1, MRP3, and breast cancer resistance protein, using immunohistochemistry and electron microscopy. In addition, gene expression profiling of CLC was performed and compared with the profile of hepatocellular carcinoma (HCC) with or without HPC features (K19 expression). In surrounding nontumoral tissue, K7-positive and K19-positive HPCs/ductular reaction were observed. More than 90% of the tumor was composed of CLC areas that showed small monotonous and/or anastomosing glands, strongly positive for K7 and K19. Especially at the tumor boundary, all cases showed a HCC-like trabecular area characterized by canalicular CD10/polyclonal carcinoembryonic antigen expression, and submembranous K7 expression, similar to intermediate hepatocytes. K7-positive/K19-positive HPCs were also seen. Out of 30 cases, 19 showed papillary and/or clear glandular formation with mucin production, representing CC areas. These three different areas showed transitional zones with each other. We observed an increased expression of MRP1, MRP3, and breast cancer resistance protein in the tumor. Electron microscopy findings in HCC-like trabecular areas confirmed the presence of HPCs and intermediate hepatocytes. HPC markers, K7, K19, prominin-1, receptor for stem cell factor c-kit, octamer-4 transcription factor, and leukemia inhibitory factor were upregulated (P < 0.05), while albumin was downregulated in CLC (P = 0.007) toward K19-negative HCCs. Comparison of CLC with K19-positive HCCs indicated a high homology. CONCLUSION All these findings highly suggest a progenitor cell origin of CLC.
