Abstract
Background
Survival data for patients with advanced cholangiocarcinoma are very sparse in India. We performed this study to find the median overall survival of patients with advanced cholangiocarcinoma and to identify prognostic factors for survival.
Methods
This is a retrospective study of 30 patients with inoperable and metastatic cholangiocarcinoma treated with cisplatin and gemcitabine chemotherapy. Overall survival was estimated by the Kaplan–Meier method. Univariate and multivariate analyses were performed to determine the impact of age, gender, performance status, carbohydrate antigen (CA) 19.9, liver function test on survival. Data were analyzed using SPSS version 21.
Results
The mean age of the population was 47.5 years (±14.5). The most common presenting complaint was jaundice followed by abdominal pain. Extrahepatic cholangiocarcinoma comprised of 86%. Median number of cycles was 4 and the response rate was 46.6% (partial response and stable disease) The median overall survival was 9 months (95% confidence interval = 6.0–11.8 months). The median survival of patients with Eastern Cooperative Oncology Group performance score < 2 and ≥2 were 15.6 and 4.2 months (
p
= 0.002), respectively. The median overall survival for patients with albumin > 3.0 g/dL was 12.1 and 4.5 months for < 3.0 g/dL (
p
= 0.039). Patients with CA 19.9 < 200 U/mL had a better overall survival (13.2 months) than those above 200 U/mL (5.6 months) (
p
= 0.001). In the multivariate analysis, performance status was found to be the only independent prognostic factor.
Conclusion
Advanced cholangiocarcinoma has a poor prognosis. Performance status, serum albumin, and CA 19.9 were found to be prognostic.

Abstract
Background Surgical resection of gallbladder cancer with negative margins is the only potentially curative therapy. Most patients with gallbladder cancer are diagnosed in an advanced stage and, despite the availability of several chemotherapies, the prognosis remains dismal. We report a case of locally advanced gallbladder cancer that was successfully treated with effective cisplatin plus gemcitabine, followed by curative resection. Case presentation A 55-year-old Japanese female was hospitalized with right hypochondrial pain. Enhanced computed tomography revealed a 49 × 47 mm mass at the neck of the gallbladder, with suspected invasion of the liver and right hepatic artery. Endoscopic retrograde cholangiopancreatography demonstrated displacement of the upper bile duct. Intraductal ultrasonography showed irregular wall thickening and disappearance of the wall structure in bile ducts from the B4 branch to distal B2 and B3. Percutaneous transhepatic biliary biopsy revealed a poorly differentiated carcinoma. The patient was diagnosed with unresectable gallbladder cancer (T4N0M0 stage IVA). Cisplatin plus gemcitabine chemotherapy was initiated. After six courses of chemotherapy, enhanced computed tomography showed that the mass in the neck of the gallbladder had shrunk to 30 mm, Endoscopic retrograde cholangiopancreatography showed improvement of the hilar duct stenosis. A biopsy of the bile duct mucosa showed no malignant cells in the branch of the left and right hepatic ducts, the left hepatic duct, or the intrapancreatic ducts. The patient underwent conversion surgery with right and segment 4a liver resection, extrahepatic duct resection, and cholangiojejunostomy. The histopathologic diagnosis showed that the tumor cells had shrunk to 2 × 1 mm, and that R0 resection of the T2aN0M0 stage IIA tumor was successful. Conclusion Although conversion surgery for gallbladder cancer is rarely possible, curative resection may offer a better prognosis, and it is important to regularly pursue possibilities for surgical resection even during chemotherapy.

Role of Adjuvant Chemotherapy in Resected T2N0 Gall Bladder Cancer. J Gastrointest Surg 2019; 23:2232-2238. [PMID: 30706378 DOI: 10.1007/s11605-019-04104-4] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2018] [Accepted: 01/01/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Management of operable gall bladder cancer (GBC) is closely related to its tumor (T) and nodal (N) status. The magnitude of benefit with adjuvant chemotherapy in completely resected, node negative T2 cancers is not completely defined. MATERIALS AND METHODS Retrospective analysis of patients diagnosed with pathological T2N0 (stage II, 7th edition AJCC) GBCs from January 2011 to June 2016 was evaluated for adverse risk factors, adjuvant treatment received, recurrence-free survival (RFS), and overall survival (OS). Survival analysis was done using Kaplan-Meier and Cox regression tools. RESULTS Of the 88 patients included, 30 received adjuvant chemotherapy while 58 were observed. The OS and RFS in the entire cohort were 82.9% and 62.7%, respectively, at a median follow-up of 44.18 months. The OS and RFS in the chemotherapy group were 85.1% and 76.4% while it was 81.4% and 55.5% in the observation group (p = 0.50). Recurrent disease was seen in 30.7%.The presence of lymphovascular invasion predicted inferior RFS (p = 0.031). CONCLUSIONS Adjuvant chemotherapy may reduce distant failure rates but did not improve OS in completely resected T2N0 GBC patients in this study. LVI predicted inferior RFS in T2N0 patients. An evaluation of adverse prognostic factors would help design personalized treatment strategies for this select cohort of T2N0 GBC.

Abstract
BACKGROUND Little is known about the value of portal vein (PV) resection in distal cholangiocarcinoma. The aim of this study was to evaluate the clinical significance of PV resection in distal cholangiocarcinoma. METHODS Patients who underwent pancreatoduodenectomy (PD) for distal cholangiocarcinoma between 2001 and 2010 at one of 31 hospitals in Japan were reviewed retrospectively with special attention to PV resection. Short- and long-term outcomes were evaluated. RESULTS In the study interval, 453 consecutive patients with distal cholangiocarcinoma underwent PD, of whom 31 (6·8 per cent) had combined PV resection. The duration of surgery (510 versus 427 min; P = 0·005) and incidence of blood transfusion (48 versus 30·7 per cent; P = 0·042) were greater in patients who had PV resection than in those who did not. Postoperative morbidity and mortality were no different in the two groups. Several indices of tumour progression, including high T classification, lymphatic invasion, perineural invasion, pancreatic invasion and lymph node metastasis, were more common in patients who had PV resection. Consequently, the incidence of R1/2 resection was higher in this group (32 versus 11·8 per cent; P = 0·004). Survival among the 31 patients with PV resection was worse than that for the 422 patients without PV resection (15 versus 42·4 per cent at 5 years; P < 0·001). Multivariable analyses revealed that age, blood loss, histological grade, perineural invasion, pancreatic invasion, lymph node metastasis and surgical margin were independent risk factors for overall survival. PV resection was not an independent risk factor. CONCLUSION PV invasion in distal cholangiocarcinoma is associated with locally advanced disease and several negative prognostic factors. Survival for patients who have PV resection is poor even after curative resection.

Abstract
Most patients with intrahepatic cholangiocarcinoma (IH-CCA) are unresectable and treatment options are limited. This study evaluates the efficacy of hepatic artery infusion (HAI) chemotherapy in patients whose disease is not initially treatable with resection. We selected patients with unresectable IH-CCA treated only with HAI chemotherapy at our centre between January 2008 and December 2012. We compared our outcome, using mRECIST, with published results of patients treated with systemic chemotherapy during the same period. Eleven patients underwent HAI chemotherapy with fluorouracil and oxaliplatin after placement of an HAI pump. A CT scan performed after the sixth cycle of therapy revealed that 5 of them had partial hepatic response (more than 45 %), 2 stable disease and 4 showed clear signs of disease progression. The average survival of the entire group was 17.6 months. Three of the patients with partial hepatic response underwent resection and 2 had more than 70 % tumour necrosis, both of whom are still alive and disease free. The median survival of patients with liver-only disease treated with systemic chemotherapy, who were not submitted for resection, was 15.3 months. HAI chemotherapy enables this small group of patients to have their unresectable IH-CCA disease converted into a resectable one, thus confirming its role in treatment of this disease.

Abstract
BACKGROUND Pancreatic carcinoma is often inoperable, carries a poor prognosis, and is commonly complicated by malignant biliary obstruction. Phase I/II studies have demonstrated good safety and early stent patency using endoscopic biliary radiofrequency ablation (RFA) as an adjunct to self-expanding metal stent (SEMS) insertion for biliary decompression. AIM To analyze the clinical efficacy of endobiliary RFA. METHODS Retrospective case-control analysis was carried out for 23 patients with surgically unresectable pancreatic carcinoma and malignant biliary obstruction undergoing endoscopic RFA and SEMS insertion and 46 controls (SEMS insertion alone) in a single tertiary care center. Controls were stringently matched for age, sex, metastases, ASA/comorbidities. Survival, morbidity, and stent patency rates were assessed. RESULTS RFA and control groups were closely matched-ASA 2.35 ± 0.65 versus 2.54 ± 0.50, p = 0.086; metastases 9/23 (39.1%) versus 18/46 (39.1%), p = 0.800; chemotherapy 16/23 (69.6%) versus 24/46 (52.2%), p = 0.203. Median survival in RFA group was 226 days (IQR 140-526 days) versus 123.5 days (IQR 44-328 days) in controls (p = 0.010). RFA was independently predictive of survival at 90 days (OR 21.07, 95% CI 1.45-306.64, p = 0.026) and 180 days (OR 4.48, 95% CI 1.04-19.30, p = 0.044) in multivariate analysis. SEMS patency rates were equivalent in both groups. RFA was well tolerated with minimal side effects. CONCLUSIONS Endoscopic RFA is a safe and efficacious adjunctive treatment in patients with advanced pancreatic malignancy and biliary obstruction and may confer early survival benefit. Randomized prospective clinical trials of this new modality are mandated.

Abstract
BACKGROUND Several unfavorable prognostic factors have been proposed for peripheral cholangiocarcinoma (PCC) in patients undergoing hepatectomy, including gross type of tumor, vascular invasion, lymph node metastasis, a high carbohydrate antigen 19-9 level, and a positive resection margin. However, the clinical effect of a positive surgical margin on the survival of patients with PCC after hepatectomy still needs to be clarified due to conflicting results. METHODS A total of 224 PCC patients who underwent hepatic resection with curative intent between 1977 and 2007 were retrospectively reviewed. Eighty-nine patients had a positive resection margin, with 62 having a microscopically positive margin and 27 a grossly positive margin (R2). The clinicopathological features, outcomes, and recurrence pattern were compared with patients with curative hepatectomy. RESULTS PCC patients with hepatolithiasis, periductal infiltrative or periductal infiltrative mixed with mass-forming growth, higher T stage, and more advanced stage tended to have higher positive resection margin rates after hepatectomy. PCC patients who underwent curative hepatectomy had a significantly higher survival rate than did those with a positive surgical margin. When PCC patients underwent hepatectomy with a positive resection margin, the histological grade of the tumor, nodal positivity, and chemotherapy significantly affected overall survival. Locoregional recurrence was the most common pattern of recurrence. CONCLUSION A positive resection margin had an unfavorable effect on overall survival in PCC patients undergoing hepatectomy. In these patients, the prognosis was determined by the biology of the tumor, including differentiation and nodal positivity, and chemotherapy increased overall survival.

Differential expression of cholecystokinin A receptor in gallbladder cancer in the young and elderly suggests two subsets of the same disease? BIOMED RESEARCH INTERNATIONAL 2014; 2014:625695. [PMID: 25025063 PMCID: PMC4082861 DOI: 10.1155/2014/625695] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Revised: 05/27/2014] [Accepted: 05/27/2014] [Indexed: 12/18/2022]
Abstract
Background. Cholecystokinin type A receptor (CCKAR) is known to be overexpressed in variety of human malignancies but information regarding its expression in gallbladder cancer (GBC) is limited. Attempts were now made to investigate expression pattern of CCKAR mRNA and protein in controls and GBC patients and correlate it with various clinicopathological parameters following surgical resection. Materials and Methods. Gallbladder tissue samples from 64 subjects (GBC: 39; control: 25) were studied. Expression of CCKAR mRNA was evaluated by reverse transcriptase-polymerase chain reaction and confirmed using real-time polymerase chain reaction. Protein expression was studied by enzyme-linked immunosorbent assay. Results. Significantly higher expression of CCKAR mRNA (P < 0.0001) and protein (P < 0.0001) was observed in GBC tissues. Overexpression was also observed for stage III and in moderately and poorly differentiated tumors. When the clinicopathological parameters were compared, we found age dependent decrease in CCKAR expression. Relatively higher expression of CCKAR was observed in younger patients (age < 45 years) having more aggressive disease when compared with elderly ones (age ≥ 45 years). Conclusions. Age related differential expression of CCKAR in GBC may suggest two possible variants of the disease in this endemic belt.

Abstract
OBJECTIVE The aim of this study was to analyze the efficacy and feasibility of gemcitabine monotherapy in patients with unresectable advanced or recurrent biliary tract cancer (BTC). METHODS Six patients with unresectable advanced BTC and 12 patients with recurrent BTC received gemcitabine monotherapy. Gemcitabine (800-1,000 mg/m²) was administered intravenously over 30 minutes on days 1, 8, and 15 every 28 days. Disease and toxicity were assessed once a week in all patients until the completion of gemcitabine treatment. Computed tomographic/magnetic resonance imaging studies were done every 8 weeks during chemotherapy, and every 4 weeks if progressive disease was suspected. Tumor response was determined according to the Response Evaluation Criteria in Solid Tumors. Toxicity was assessed using the National Cancer Institute Common Toxicity Criteria version 2.0. The time to progression and survival time were also calculated. RESULTS In patients with unresectable BTC, the overall response rate and the median time to progression for patients with partial response or stable disease was 66.7% and 5.68 months, respectively. Clinical benefit was observed in 3 patients with stable disease (50%). The median survival time was 5.2 months. In patients with recurrent BTC, 4 patients (33%) obtained partial responses and 2 patients (17%) had stable disease. The median time to progression was 8.2 months. Six of 12 patients (50%) obtained clinical benefit. The median survival time for cancer of the intrahepatic bile duct, the extrahepatic bile duct, and the ampulla of Vater were 2.8 months, 8.5 months, and 10.7 months, respectively. No significant correlation between the survival time and the resectability of the initial procedure (R number) was detected. The survival time for patients with a performance status of 0 or 1 was significantly longer than that for patients with a performance status of 2 (P=0.0051). Neither grade 3/4 hematologic toxicity nor grade 3/4 nonhematologic toxicity was observed. No treatment-related deaths were observed. CONCLUSION Gemcitabine monotherapy may provide a more favorable prognosis in patients with advanced BTC than does best supportive care alone. Moreover, this regimen may represent a therapeutic option for the adjuvant setting in patients with BTC.

Abstract
BACKGROUND Many patients with intrahepatic cholangiocarcinoma (ICC) present with advanced and inoperable disease. Data on the safety and efficacy of intra-arterial therapy (IAT) for ICC are limited. METHODS Between 1992 and 2012, a total of 198 patients with advanced ICC treated with IAT were retrospectively identified from the databases of five major hepatobiliary institutions. Data on clinicopathological factors, morbidity, response rates, and overall survival were collected and analyzed. RESULTS Median patient age was 61 years. Median tumor size was 8.1 cm, and 47.5% patients had a solitary lesion. IAT consisted of conventional transarterial chemoembolization (cTACE) (64.7%), drug-eluting beads (DEB) (5.6%), bland embolization (TAE) (6.6%), or yttrium-90 radioembolization (23.2%). Median number of IAT sessions was 2 (range 1-8). The median time between IAT sessions was 48 days. The periprocedural morbidity was 29.8%; most complications were minor (n = 43); however, 16 patients had a grade 3-4 complication. Assessment of tumor response revealed complete or partial response in 25.5% patients, while 61.5% had stable disease; 13.0% had progressive disease. Median overall survival was 13.2 months and did not differ on the basis of the type of IAT (cTACE, 13.4 months vs. DEB 10.5 months vs. TAE, 14.3 months vs. yttrium-90, 11.3 months; P = 0.46). IAT response on modified response evaluation criteria in solid tumors (mRECIST; hazard ratio for complete-partial response 0.49, 95% confidence interval 0.30-0.81; P < 0.001) was independently associated with better survival. CONCLUSIONS IAT for ICC was safe and led to stable disease or partial to complete response in up to three-quarters of patients. Among patients with an IAT response, overall survival was prolonged. The role of IAT therapy for ICC warrants further prospective evaluation in clinical trials.

Abstract
BACKGROUND Systemic chemotherapy is the treatment of choice for inoperable (advanced or metastatic) cholangiocarcinoma. According to phase II and III trials, regimens combining 5-fluorouracil (5FU) or gemcitabine with a platinum salt have provided an overall response rate of 12-50% with a median overall survival of 5-16 months. METHODS This was a retrospective analysis of 78 consecutive cases of inoperable cholangiocarcinoma treated by palliative chemotherapy from July 2005 to November 2009 in one center. We firstly aimed to evaluate the impact of palliative chemotherapy in terms of survival and secondly to analyze possible related prognostic factors. RESULTS This cohort included 25 female and 53 male patients, with a mean age of 60.8 ± 11.4 years. Intrahepatic and extrahepatic cholangiocarcinoma were observed in 57 and 21 patients, respectively. First-line chemotherapy regimens were as follows: gemcitabine (n = 7), gemcitabine plus oxaliplatin (with or without cetuximab; n = 62) and 5FU plus cisplatin (n = 9). None of the patients achieved a complete response. The partial response rate was 35.9% (27/78), and the stable disease rate was 26.9% (21/78), giving a disease control rate of 62.8%. At the time of this analysis, with a median follow-up of 18 months, 13 patients were survivors. Median overall survival was 10 months [95% confidence interval (CI) 7-12], and median progression-free survival was 7 months (95% CI 6-8). Upon univariate analysis, only the distribution of the disease was significantly linked with prognosis, with a median overall survival of 10 months (95% CI 10-24) for solitary tumors versus 7 months (95% CI 6-11) in the case of infiltrative or multifocal tumors (p = 0.039). CONCLUSION The disease control rate, overall survival and progression free-survival in this single-center retrospective study were in agreement with earlier reports. Specific features of this cohort were a large proportion of cholangiocarcinoma with associated cirrhosis (n = 30/78, 38.5%), mostly intrahepatic (n = 25/30, 83.5%). This confirms the increasing incidence of intrahepatic localization and the epidemiological link recently reported between intrahepatic biliary tract carcinoma and cirrhosis.

Abstract
BACKGROUND Unresectable cholangiocarcinoma (CCC) has a poor prognosis. Patients with intrahepatic CCC have a very limited benefit from systemic chemotherapy (ChT). The aim of this prospective study was to evaluate the feasibility, safety, and efficacy of conventional transarterial chemoembolization (cTACE) with mitomycin-C and of irinotecan-eluting beads (iDEB-TACE), and to retrospectively compare them with ChT with oxaliplatin and gemcitabine. MATERIALS AND METHODS Between June 2002 and June 2010, three independent prospective trials were carried out and compared retrospectively. Following predefined study protocols, 26 patients with histologically proven intrahepatic CCC were treated with iDEB-TACE (200 mg irinotecan), 10 patients were treated with cTACE using 15 mg mitomycin-C mixed with 5-10 ml of ionized oil (lipiodol), followed by embolization with gelfoam, and 31 patients received systemic ChT with gemcitabine and oxaliplatin. Treatment response and progression-free survival (PFS) were assessed by computer tomography or MRI every 2 months according to Response Evaluation Criteria in Solid Tumors. Clinical and laboratory data were assessed for side-effects according to National Cancer Institute-Common Toxicity Criteria. RESULTS iDEB-TACE resulted in PFS of 3.9 months and overall survival (OS) of 11.7 months, compared with a PFS of 1.8 months and OS of 5.7 months, respectively, in patients treated with cTACE, and a PFS of 6.2 months and OS of 11.0 months, respectively, in patients treated with oxaliplatin and gemcitabine. The medium follow-up of patients treated with iDEB-TACE was 12 months; 2 months after treatment, 13 patients (50%) had progressive disease, 11 patients (42%) had stable disease, and one patient had a partial response and became eligible for secondary liver resection. Local tumor control was achieved in 66% of patients; 4% had a partial response, 62% had stable disease, and 27% progressive disease. Common Toxicity Criteria grade III or IV toxicities for iDEB-TACE were abdominal pain (n=7), hepatic abscess (n=1), pleural empyema due to biliary leakage (n=1), and one death due to cholangitis with hepatic failure in a patient with liver cirrhosis. No hematological side-effects were observed. Almost every patient experienced a 'postembolization syndrome' with low-grade fever, nausea, and abdominal pain for up to 2 weeks. CONCLUSION This is the first study demonstrating that treatment of patients suffering from intrahepatic CCC with iDEB-TACE is safe in patients with normal liver function, and results in a prolongation of PFS and OS. Local tumor control, PFS and OS seem similar to systemic ChT with oxaliplatin and gemcitabine, but superior to cTACE.

Abstract
Patients with cholangiocarcinomas often present with unresectable disease, which is associated with a poor clinical outcome and survival. A number of palliative options are available to patients; the evaluated article presented experience from a single institution of treating cholangiocarcinoma, either unresectable or locally advanced, with conformal radiotherapy and concurrent chemotherapy. Patients who had received biliary radiation for cholangiocarcinoma were identified from the hospital database, and information on the patients sourced from notes and reports. In total, 20 patients with a diagnosis of biliary tract cancer were included and received radical conformal radiotherapy with concurrent cisplatin/5-fluorouracil and sequential gemcitabine. The median overall survival was 20.4 months and the relapse-free survival was 9.6 months. Treatment failure within the radiotherapy field was recorded in 45% of patients; adverse events were minimal. This study adds to the retrospective data available regarding the management of patients with biliary tract carcinomas, and we have found in our own cohort of 45 patients that gemcitabine/platinum was a more effective combination than monotherapy.

Abstract
Background: Advanced biliary cancer is often treated with fluoropyrimidine-based chemotherapy. In this study, we evaluated the efficacy and tolerability of a combination of S-1, an oral fluoropyrimidine prodrug, and oxaliplatin in patients with metastatic biliary cancer. Methods: Patients with histologically confirmed metastatic biliary cancer and no history of radiotherapy or chemotherapy were enrolled. Oxaliplatin was administered intravenously (130 mg m−2), followed by 14-day administration of oral S-1 (40 mg m−2 twice daily) with a subsequent 7-day rest period every 21 days. Pharmacokinetic analysis of S-1 was performed at cycle 1. Patients were genotyped for CYP2A6 polymorphisms (*1, *4, *7, *9 or *10), and pharmacokinetic and clinical parameters compared according to the CYP2A6 genotype. Results: In total, 49 patients were evaluated, who received a median of four cycles. The overall response rate was 24.5%. Median progression-free and overall survival was 3.7 and 8.7 months, respectively. The most common haematological grade 3 out of 4 toxicity was neutropenia (14%), while non-hematological grade 3 out of 4 toxicities included anorexia (14%), nausea (12%), asthenia (10%), vomiting (10%), and diarrhoea (4%). Biotransformation of S-1 (AUC0−24 h of 5-fluorouracil/AUC0−24 h of tegafur) was 1.85-fold higher for the *1/*1 group than for the other groups (90% confidence interval 1.37–2.49). Diarrhoea (P=0.0740), neutropenia (P=0.396), and clinical efficacy (response rate, P=0.583; PFS, P=0.916) were not significantly associated with CYP2A6 genotype, despite differences in 5-FU exposure. Conclusion: The combination of S-1 and oxaliplatin appears to be active and well tolerated in patients with metastatic biliary cancer, and thus is feasible as a therapeutic modality. CYP2A6 genotypes are associated with differences in the biotransformation of S-1. However, the impact of the CYP2A6 polymorphism on variations in clinical efficacy or toxicity requires further evaluation.

Abstract
The prognosis of patients with nonresectable hilar biliary tract cancer (hBTC) is poor. Responsiveness to chemotherapy or radiochemotherapy is moderate at best, and patients are at a high risk of dying early from complications of local tumor infiltration (e.g., cholestasis, septic cholangitis, empyema or liver failure) rather than systemic disease. Therefore, palliative local therapy for the prevention of tumor complications plays a central role and still yields the longest survival times. Photodynamic therapy (PDT) is a local-ablative, tumor tissue-specific treatment currently representing the standard of care for nonresectable hBTC. Throughout the literature, PDT plus biliary drainage achieves median survival times in the range of 9-21 months (average 14-16 months), compared with approximately 6 months for drainage only. This article summarizes the recent advances in preclinical and clinical experience of PDT for hBTC, including experimental in vitro and in vivo studies, clinical studies and an overview of the ongoing clinical trials.

Abstract
OBJECTIVES No established therapy exists for unresectable intrahepatic cholangiocarcinoma (ICC). We conducted a phase I/II study to ascertain the recommended dose (RD) of hepatic arterial infusion using gemcitabine (GEM) for ICC and to assess the efficacy and safety. METHODS For patients with unresectable ICC, GEM was administered through the hepatic artery via the port system as a 30-minute infusion on days 1, 8, and 15 every 4 weeks for 5 cycles. In phase I, dosage for levels 1, 2, and 3 was set at 600, 800, and 1000 mg/m, respectively, and was increased in 3 to 6 patients at a time. Maximum tolerated dose was defined as a dosage resulting in dose-limiting toxicity in 2 of 3 patients or 3 of 6 patients, and RD was estimated during the first cycle. In the phase II, more RD patients were added to assess tumor response and toxicity. RESULTS During the phase I, 16 patients were enrolled. Maximum tolerated dose was not reached. Assuming RD at 1000 mg/m, the phase II enrolled a total of 13 patients. The following Grade 3 toxicities were observed: neutropenia 20%, increased gamma-glutamyl transpeptidase 8%, increased aspartate aminotransferase 4%, increased alanine aminotransferase 4%, increased bilirubin 4%, nausea 4%, and fatigue 4%. The tumor response rate was 7.7% (complete response 0, partial response 1, stable disease 8, and progressive disease 4). CONCLUSION Whereas the toxicity of hepatic arterial infusion with 1000 mg/m GEM for ICC was tolerable, expected efficacy could not be obtained, thus suggesting only minimal activity.

Abstract
PURPOSE OF REVIEW Primary sclerosing cholangitis (PSC) is being diagnosed with increasing frequency. The most feared complication is the presence or development of cholangiocarcinoma (CCA). The present review summarizes recent data with regards to diagnosis, pathobiology and treatment. RECENT FINDINGS Several investigations have focused on aspects of the molecular biology of CCA in general; such data should be explored now in the context of PSC-related CCA to yield new diagnostic markers and approaches for therapy. SUMMARY CCA has to be suspected in any new PSC patient presenting with jaundice. Exploration should include carbohydrate antigen19-9 and two imaging techniques. Endoscopic cholangioscopy might become very rewarding. Important progress has been achieved in liver transplantation by the use of preoperative radio-chemotherapy. Molecular biology points to inflammation-induced cytokines with mutagenic action and to the relevance of extracellular matrix proteins for invasion but also for proliferation. Micro-RNAs prove to be very important in the control of cell proliferation, differentiation and apoptosis. Mutated p53, cyclins, wnt/beta-catenin signaling, proliferation indices, mucins, carbohydrate antigen19-9, CRP and aneuploidy appear to hold significant potential as predictors of outcome in CCA. It is expected that the further unraveling of these molecular processes will ultimately lead to development of tests allowing early diagnosis and to development of medical approaches to retard tumor formation or recurrence following surgical interventions.

Decreased expression of focal adhesion kinase is associated with a poor prognosis in extrahepatic bile duct carcinoma. Hum Pathol 2010; 41:859-66.

Abstract
Extrahepatic bile duct (EBD) carcinoma is a relatively rare neoplasm worldwide, and its prognostic outcome remains unfavorable. Therefore, it is necessary to investigate molecular biologic features of EBD carcinomas. Focal adhesion kinase (FAK) plays a pivotal role in cell adhesion, survival, migration, and signal transduction, but FAK expression in EBD carcinomas has not been evaluated. We measured FAK expression in 76 EBD carcinomas using immunohistochemistry and evaluated its correlation with tumor progression, clinicopathologic factors, and patient outcome. FAK was expressed specifically in the cytoplasm of all normal biliary epithelia (100%). Most dysplastic epithelia also showed positive FAK expression except for 2 cases (92%), whereas EBD carcinomas showed positive FAK expression in 53 (77%) of 76 cases (P < .001, versus normal epithelia). FAK expression tended to be gradually reduced along as dysplasia progressed to carcinoma. Although FAK expression had no association with clinicopathologic factors, the positive FAK expression group showed significantly better survival than the negative FAK expression group (P < .05). However, FAK expression was not an independent prognostic factor by multivariate analysis. In conclusion, FAK expression was significantly lower in EBD carcinomas than in normal biliary epithelia and decreased expression of FAK seemed to be indicative of a poor prognosis, suggesting that FAK might play an inhibitory role for tumor progression in EBD carcinomas. It is important to notice the role of FAK in tumor progression when treatments targeting FAK are performed.

Abstract
BACKGROUND AND AIM The combination of photodynamic therapy and biliary stenting seems to be beneficial in the palliative treatment of unresectable cholangiocarcinoma. We aimed to assess the accuracy of photodynamic therapy in a single centre. METHODS Fourteen selected patients, with jaundice related to unresectable cholangiocarcinoma, underwent photodynamic therapy and biliary stenting (with or without chemotherapy). Photofrin was injected intravenously (2 mg/kg) 2 days before intraluminal photoactivation. In case of malignant progression, photodynamic therapy was repeated. The outcome parameters were overall survival and quality of life. RESULTS There were eight men and six women (median age: 67 [42-81]). Unresectability was related to a low Karnofski index (n = 2), peritoneal carcinomatosis (n = 4), vascular involvement (n = 3), invasion of the hepatoduodenal ligament (n = 2) and an under-sized liver remnant (n = 3). Biliary stenting was efficient (> or = 50% total bilirubin) in 78.5% of cases. Eight patients developed cholangitis. The mean number of photodynamic therapy procedures was two (1-4). Six (43%) patients needed > or = 2 procedures. No severe toxicity was noted. Photodynamic therapy improved the Karnofski index in 64% of cases. Six (42.8%) patients received concomitant chemotherapy (gemcitabine). The median survival time was 13.8 [0.7-29.2] months. The 3-, 6- and 12-month survival rates were 85%, 77% and 77%, respectively. CONCLUSION These results confirm the beneficial effect of biliary drainage, photodynamic therapy and chemotherapy for unresectable cholangiocarcinoma in selected patients with jaundice.

Abstract
This study reports a case of unresectable intrahepatic mass-forming cholangiocarcinoma which showed a dramatic response to gemcitabine that led to curative resection and a long-term survival of more than five years. Six and five cycles of gemcitabine monotherapy were administered separately over a three-year period and a radical excision was performed at 4.5 years after diagnosis. This case indicates the role of gemcitabine as a neoadjuvant chemotherapeutic agent for cholangiocarcinoma and guarantees a randomized controlled prospective study.
