Clinical value of K-ras codon 12 analysis and endobiliary brush cytology for the diagnosis of malignant extrahepatic bile duct stenosis. (1/179)

Extrahepatic biliary stenosis can be caused by benign and malignant disorders. In most cases, a tissue diagnosis is needed for optimal management of patients, but the sensitivity of biliary cytology for the diagnosis of a malignancy is relatively low. The additional diagnostic value of K-ras mutational analysis of endobiliary brush cytology was assessed. Endobiliary brush cytology specimens obtained during endoscopic retrograde cholangiopancreaticography were prospectively collected from 312 consecutive patients with extrahepatic biliary stenosis. The results of conventional light microscopic cytology and K-ras codon 12 mutational analysis were compared and evaluated in view of the final diagnosis made by histological examination of the stenotic lesion and/or patient follow-up. The sensitivities of cytology and mutational analysis to detect malignancy were 36 and 42%, respectively. When both tests were combined, the sensitivity increased to 62%. The specificity of cytology was 98%, and the specificity of the mutational analysis and of both tests combined was 89%. Positive predictive values for cytology, mutational analysis, and both tests combined were 98, 92, and 94%, whereas the corresponding negative predictive values were 34, 34, and 44%, respectively. The sensitivity of K-ras mutational analysis was 63% for pancreatic carcinomas compared to 27% for bile duct, gallbladder, and ampullary carcinomas. K-ras mutational analysis can be considered supplementary to conventional light microscopy of endobiliary brush cytology to diagnose patients with malignant extrahepatic biliary stenosis, particularly in the case of pancreatic cancer. The presence of a K-ras codon 12 mutation in endobiliary brush cytology per se supports a clinical suspicion of malignancy, even when the conventional cytology is negative or equivocal.  (+info)

Metachronous bile duct cancer in a patient surviving for a decade and undergoing curative surgery twice. (2/179)

We report a 75-year-old woman with metachronous bile duct cancer who underwent curative resection twice and has survived for a decade. In 1989, she was admitted because her serum alkaline phosphatase level was elevated. Computed tomography (CT) showed a low-density mass, 2 cm in diameter, at the left hepatic duct and intrahepatic bile duct dilatation in the left lobe. We diagnosed the lesion as an intrahepatic bile duct cancer and performed extended left hepatic lobectomy with systematic lymph node dissection. The histological diagnosis was a well differentiated cholangiocellular carcinoma with hepatic hilar and celiac lymph node metastases (T1N2M0, Stage IVB). In 1996, she was re-admitted with obstructive jaundice. CT showed a slightly enhanced mass, 4 cm in diameter, in the pancreatic head. After reducing the jaundice by percutaneous transhepatic biliary drainage, pancreatoduodenectomy was performed. The histological diagnosis of this lesion was a moderately differentiated adenocarcinoma originating from the intrapancreatic bile duct. Ten years after the first operation, she is leading a normal daily life with no cancer recurrence. These findings suggest that repeated curative surgery can result in a long-term survival of patients with metachronous bile duct cancer.  (+info)

Partial hepatectomy and bile duct ligation in rainbow trout (Oncorhynchus mykiss): histologic, immunohistochemical and enzyme histochemical characterization of hepatic regeneration and biliary hyperplasia. (3/179)

Hepatic regeneration following partial hepatectomy (PH) and biliary hyperplasia subsequent to bile duct ligation (BDL) were characterized in rainbow trout (Oncorhynchus mykiss) by light microscopy using routine and special (immunohistochemical and enzyme histochemical) stains. Both PH and BDL involved initial hypertrophy and hyperplasia of bile preductular epithelial cells (BPDECs). BPDECs are small oval cells that form junctional complexes with hepatocytes and bile ductular cells and are commonly found in hepatic tubules of teleost liver. Proliferating BPDECs transitioned through intermediate cell types before final differentiation into large basophilic hepatocytes (following PH) or biliary epithelial cells (after BDL). Normal BPDECs and hepatocytes were both negative for cytokeratin intermediate filaments in control fish when screened with the monoclonal antibody AE1/AE3. In contrast, hyperplastic BPDECs and their progeny (intermediate cells, immature hepatocytes, ductal epithelial cells) were all strongly cytokeratin positive. Cytokeratin expression was transient in newly differentiated hepatocytes (expression decreased as hepatocytes acquired characteristics consistent with full differentiation) but was permanent in biliary epithelial cells (expression was very strong in large mature ducts). BPDECs, intermediate cells, and immature ductal cells were also strongly positive for alkaline phosphatase following BDL. Chronology of histologic events and cytokeratin and enzyme expression all support the hypothesis that BPDECs possess the capacity to differentiate into either hepatocytes or biliary epithelial cells. Thus, BPDECs may be the teleost equivalent of a bipolar hepatic stem cell in mammals.  (+info)

Postoperative bile duct strictures: management and outcome in the 1990s. (4/179)

OBJECTIVE: To describe the management and outcome after surgical reconstruction of 156 patients with postoperative bile duct strictures managed in the 1990s. SUMMARY BACKGROUND DATA: The management of postoperative bile duct strictures and major bile duct injuries remains a challenge for even the most skilled biliary tract surgeon. The 1990s saw a dramatic increase in the incidence of bile duct strictures and injuries from the introduction and widespread use of laparoscopic cholecystectomy. Although the management of these injuries and short-term outcome have been reported, long-term follow-up is limited. METHODS: Data were collected prospectively on 156 patients treated at the Johns Hopkins Hospital with major bile duct injuries or postoperative bile duct strictures between January 1990 and December 1999. With the exception of bile duct injuries discovered and repaired during surgery, all patients underwent preoperative percutaneous transhepatic cholangiography and placement of transhepatic biliary catheters before surgical repair. Follow-up was conducted by medical record review or telephone interview during January 2000. RESULTS: Of the 156 patients undergoing surgical reconstruction, 142 had completed treatment with a mean follow-up of 57.5 months. Two patients died of reasons unrelated to biliary tract disease before the completion of treatment. Twelve patients (7.9%) had not completed treatment and still had biliary stents in place at the time of this report. Of patients who had completed treatment, 90. 8% were considered to have a successful outcome without the need for follow-up invasive, diagnos tic, or therapeutic interventional procedures. Patients with reconstruction after injury or stricture after laparoscopic cholecystectomy had a better overall outcome than patients whose postoperative stricture developed after other types of surgery. Presenting symptoms, number of stents, interval to referral, prior repair, and length of postoperative stenting were not significant predictors of outcome. Overall, a successful outcome, without the need for biliary stents, was obtained in 98% of patients, including those requiring a secondary procedure for recurrent stricture. CONCLUSIONS: Major bile duct injuries and postoperative bile duct strictures remain a considerable surgical challenge. Management with preoperative cholangiography to delineate the anatomy and placement of percutaneous biliary catheters, followed by surgical reconstruction with a Roux-en-Y hepaticojejunostomy, is associated with a successful outcome in up to 98% of patients.  (+info)

Genetic alterations and growth pattern in biliary duct carcinomas: loss of heterozygosity at chromosome 5q bears a close relation with polypoid growth. (5/179)

Biliary duct carcinomas (BDCs) are relatively rare and the carcinogenic mechanisms underlying their induction are poorly understood. There are two growth patterns, polypoid and non-polypoid infiltrative type, but little information is available concerning the relation between growth pattern and genetic alterations. A comparative study was therefore conducted to clarify if differences in genetic changes, including loss of heterozygosity (LOH) at 5q, 9p, 17p, and 18q, and K-ras mutations exist between polypoid and non-polypoid infiltrative type BDCs. LOH analysis was performed using microsatellite markers and K-ras point mutations were analysed by dot blot hybridisation. The incidences of changes for polypoid and non-polypoid infiltrative types were 73% and 26% on 5q, 63% and 59% on 9p, 55% and 50% on 17p, and 20% and 18% on 18q, and 25% and 27% for K-ras mutations. Most importantly, we found the frequency of 5qLOH to be significantly higher with polypoid growth than in the non-polypoid infiltrative type (p<0.05), especially in extrahepatic duct carcinomas (p<0.05). The incidences of other genetic alterations (LOH at 9p, 17p, and 18q, and K-ras mutations) showed similar rates with both tumour types. The present data suggest that 5qLOH may have a close relation with polypoid growth in BDCs.  (+info)

Is preventive resection of the extrahepatic bile duct necessary in cases of pancreaticobiliary maljunction without dilatation of the bile duct? (6/179)

BACKGROUND: No consensus has been reached on whether preventive resection of the extrahepatic bile duct is necessary in cases of pancreaticobiliary maljunction (PBM) without dilatation of the extrahepatic bile duct (undilated type). METHODS: Sixty-eight patients with PBM underwent corrective surgery and several clinical characteristics and pathological findings including K-ras point mutation were evaluated. RESULTS: Unlike dilated bile duct, none of the patients with undilated type duct had clinical symptoms in early childhood. In patients with either cystic or spindle type duct, amylase levels in the bile duct were >10(4) U/l, whereas those in patients with undilated type duct were <10(4) U/l. Postoperative scintigraphy of the biliary system of undilated type revealed no evidence of cholestasis. After surgery, eight patients with undilated type duct, in whom the bile duct had been preserved, had no further clinical symptoms and no evidence of malignancy. Bile duct tissue specimens revealed no hyperplasia, dysplasia or cancerous lesions and they had no K-ras mutation in undilated type. CONCLUSION: The results showed that there was little bile stasis, injury to the mucosa was mild and less genetic changes could be seen in patients with undilated type duct. Therefore, in patients without dilatation of bile duct and advanced cancer, cholecystectomy alone is sufficient.  (+info)

Restrictive cardiomyopathy in a patient with extrahepatic biliary atresia. (7/179)

The most commonly associated anomalies in patients with extrahepatic biliary atresia are cardiovascular, digestive and splenic defects. Of the cardiovascular anomalies, there are very few reports of biliary atresia with cardiomyopathy. We report the first case of a child with extrahepatic biliary atresia and restrictive cardiomyopathy. The patient was a 13-month-old boy diagnosed with extrahepatic biliary atresia at the age of 2 months, when he underwent laparotomy for definite diagnosis.Hepatic portoenterostomy was performed after confirmative cholangiogram. Recently, he developed severe cough and dyspnea, and his respiratory symptoms worsened. Chest radiograph showed cardiomegaly. Two- dimensional echocardiography showed marked biatrial enlargement. On M- mode echocardiogram, a slight increase in left ventricular dimension was seen in early diastole with a relatively good left ventricular function. Mitral inflow Doppler tracing showed an increased E-velocity (1.1 m/sec) with decreased deceleration time (75 m/sec), and increased E/A ratio (0.33). He was diagnosed as having restrictive cardiomyopathy with characteristic echocardiographic features.  (+info)

Immunohistochemical and ultrastructural study of ito cells (fat-storing cells) in response to extrahepatic bile duct ligation in broiler chickens. (8/179)

The Ito cell (fat-storing cell) lies in perisinusoidal space of liver and has a variety of functions. We investigated the immunohistochemistry and ultrastructure of Ito cells in normal and cholestatic livers of broiler chickens. Immunohistochemistry demonstrated that Ito cells expressed HHF35 muscle actin, vimentin, desmin, glial fibrillary acidic protein (GFAP), neuron-specific enolase (NSE), chromogranin A and cytokeratins in normal livers. These cells were diffusely scattered throughout the lobules. Livers treated with extrahepatic bile duct ligation (BDL) showed cholestasis, fibrosis, proliferation of biliary ductules and Ito cells. The Ito cells were frequently found in fibrotic areas and were larger in size with more extensive immunoreactivity than those of normal livers. Ultrastructural study demonstrated that Ito cells were closely associated with the production of collagen fibers in BDL livers. These findings suggest that Ito cells actively react against hepatocytic injuries and play a major role in the hepatic fibrogenesis of cholestatic livers of chickens.  (+info)

N2 - Fifty-two patients with carcinoma of the extrahepatic bile ducts were reviewed. There were 28 men and 24 women whose ages ranged from 31 to 78 years, with a mean age of 58 years. Symptoms, signs and laboratory results were primarily the result of bile duct obstruction. The most valuable diagnostic procedures were percutaneous transhepatic cholangiography and endoscopic retrograde cholangiopancreatography. In 28 patients the tumor was located in the upper, 9 in the middle and 12 in the lower common bile duct. In the other three patients the tumor was diffuse. The resectability rate was 21.2% (11/52). Of the remaining patients, 10 (19.2%) had T-tube drainage, 5 (9.6%) had biliary digestive anastomosis, 18 (34.6%) had percutaneous transhepatic biliary drainage and 8 (15.4%) had biopsy only. The histologic diagnosis was sclerosing in ...
The current Fascicle contains new information accumulated during the last ten years on tumors and tumor-like lesions of the gallbladder, extrahepatic bile ducts and Vaterian system. Because of the increasing number of laparoscopic cholecystectomies and Whipple procedures performed, surgical pathologists now have the opportunity to examine more cancer precursors, early cancers, and adenomas of the gallbladder, extrahepatic bile ducts and ampulla of Vater than previously. These lesions are discussed in detail and profusely illustrated. Likewise, lesions that closely simulate malignant neoplasms are also described and illustrated. Also included are the giant cell neoplasms and the gastrointestinal stromal tumors as well as the new subtypes of carcinomas such as large cell neuroendocrine carcinomas and adenocarcinomas with pyloric gland or foveolar phenotype. The role of immunohistochemistry in the diagnosis of a wide variety of neoplasms is emphasized, as well ...

High-grade dysplasia/carcinoma in situ (HGD/CIS) of the biliary duct margin was found to not affect the prognosis of patients with extrahepatic cholangiocarcinoma by recent studies, but it has not yet reached a conclusion. Eligible studies were searched by PubMed, PMC, MedLine, Embase, the Cochrane Library, and Web of Science, from Jan. 1, 2000 to Jun. 30, 2019, investigating the influences of surgical margin status of biliary duct on the prognosis of patients with resectable extrahepatic cholangiocarcinoma. Overall survival (OS) and local recurrence were evaluated by odds ratio (OR) with 95% confidence interval (CI). A total of 11 studies were enrolled in this meta-analysis, including 1734 patients in the R0 group, 194 patients in the HGD/CIS group, and 229 patients in the invasive carcinoma (INV) group. The pooled OR for the 1-, 2-, and 3-year OS rate between HGD/CIS group and R0 group was 0.98 (95% CI 0.65~1.50), 1.01 (95% CI 0.73~1.41), and 0.98 (95% CI 0.72~1.34), respectively. The pooled OR for

Although ductal margin status is an established prognostic factor in patients with extrahepatic cholangiocarcinoma,4-17 a small proportion of patients with positive resection margins may still survive in the long term.7-12 We also observed four 5-year survivors with positive ductal margins (Fig. 2), a fact that inspired the current study. To our knowledge, the current study is the first to demonstrate that residual carcinoma in situ differs prognostically from residual invasive ductal disease in patients with extrahepatic cholangiocarcinoma.. In the current study, which examined extrahepatic cholangiocarcinoma, 4 patients with residual carcinoma in situ at the ductal stumps died of local disease recurrence 26 months, 54 months, 99 months, and 112 months after surgical resection, respectively (Table 3). For gallbladder carcinoma, we previously reported that 2 patients with residual carcinoma in situ at the cystic ductal stumps died of local recurrence 66 months and 76 months, respectively, after ...

Evidence on the association between physical activity and risk of hepatobiliary cancers is inconclusive. We examined this association in the European Prospective Investigation into Cancer and Nutrition cohort (EPIC). We identified 275 hepatocellular carcinoma (HCC) cases, 93 intrahepatic bile duct cancers (IHBCs), and 164 non-gallbladder extrahepatic bile duct cancers (NGBCs) among 467,336 EPIC participants (median follow-up 14.9 years). We estimated cause-specific hazard ratios (HRs) for total physical activity and vigorous physical activity and performed mediation analysis and secondary analyses to assess robustness to confounding (e.g. due to hepatitis virus infection). In the EPIC cohort, the multivariable-adjusted HR of HCC was 0.55 (95% CI 0.38-0.80) comparing active and inactive individuals.

Cholestasis is defined as a decrease in bile flow due to impaired secretion by hepatocytes or to obstruction of bile flow through intra-or extrahepatic bile ducts. Therefore, the clinical definition of cholestasis is any condition in which substances normally excreted into bile are retained.
Confocal laser endomicroscopy (pCLE) provides real-time histologic imaging of human tissues at a depth of 60-70 μm during endoscopy. pCLE of the extrahepatic bile duct after fluorescein injection demonstrated a reticular pattern within fluorescein-filled sinuses that had no known anatomical correlate. Freezing biopsy tissue before fixation preserved the anatomy of this structure, demonstrating that it is part of the submucosa and a previously unappreciated fluid-filled interstitial space, draining to lymph nodes and supported by a complex network of thick collagen bundles. These bundles are intermittently lined on one side by fibroblast-like cells that stain with endothelial markers and vimentin, although there is a highly unusual and extensive unlined interface between the matrix proteins of the bundles and the surrounding fluid. We observed similar structures in numerous tissues that are subject to intermittent or rhythmic compression, including the submucosae of the entire gastrointestinal tract and

Langerhans cell histiocytosis (LCH) is an abnormal accumulation of Langerhans cells in various organs that sometimes induces organ dysfunction. LCH can affect the liver, resulting in sclerosing cholangitis and biliary cirrhosis. However, liver and bile duct involvement is usually observed in the disseminated form of LCH. We herein report a rare case of LCH localized only in the extrahepatic bile duct that resulted in severe liver cirrhosis. A 3-year-old boy with elevated liver enzymes, obstructive jaundice, and dilation of the common bile duct was referred to our institution. Contrast-enhanced computed tomography showed atrophy of the right hepatic lobe, relative hypertrophy of the left hepatic lobe, choledocholiths, and biliary debris extensively with biliary duct dilation. Magnetic resonance cholangiopancreatography revealed dilation of the intrahepatic and extrahepatic bile ducts and multiple choleliths in the gallbladder and common bile duct.

Percutaneous transhepatic cholangiography (PTC) revealed erosive disruption of the extrahepatic bile ducts by a cavitating metastasis in the porta hepatis, as well as a biliary-duodenal fistula. External-internal biliary drainage via the fistula was plagued by recurrent drain occlusion by necrotic debris. This was ultimately alleviated by successful catheterization of the distal common bile duct (CBD) through the cavity, and linking the common hepatic duct (CHD) and CBD with a Wallstent, across the cavity. This succeeded in improving internal biliary drainage and isolating the exfoliating debris of the cavity from the bile ducts.. AB - A 45-year-old woman ...

Pathologically, her tumor was diagnosed as adenosquamous carcinoma of the lower extrahepatic bile duct with final stage IVb [pT3pN3M (-)]. The prognosis of patients with adenosquamous carcinoma of the bile duct is very poor, and the reason is thought to be its tendency to invade the pancreas.

In a phase II Intergroup study (SWOG S0809) reported in the Journal of Clinical Oncology, Ben-Josef et al found that adjuvant capecitabine and gemcitabine followed by concurrent radiotherapy and capecitabine produced good survival results in patients with extrahepatic cholangiocarcinoma or gallbladder carcinoma.. Study Details. The study included 79 patients who had undergone radical resection and had stage pT2-4 or N+ or positive resection margins, M0, and a Zubrod performance status of 0 to 1. Patients received four cycles of gemcitabine 1,000 mg/m2 on days 1 and 8 and capecitabine 1,500 mg/m2/d on days 1 to 14 every 21 days followed by concurrent capecitabine 1,330 mg/m2/d and radiotherapy consisting of 45 Gy to regional lymphatics and 54 to 59.4 Gy to the tumor bed. The study was designed to estimate 2-year survival overall after R0 or R1 resection.. Of the 79 patients, 68% had extrahepatic cholangiocarcinoma, and 32% had gallbladder carcinoma; 68% had R0 resection, and 32% had R1 ...

Biliary atresia is a fibroinflammatory obstruction of extrahepatic bile duct that leads to end-stage liver disease in children. Despite advances in understanding the pathogenesis of biliary atresia, very little is known about the role of microRNAs (miRNAs) in onset and progression of the disease. In this study, we aimed to investigate the entire biliary transcriptome to identify miRNAs with potential role in the pathogenesis of bile duct obstruction. By profiling the expression levels of miRNA in extrahepatic bile ducts and gallbladder (EHBDs) from a murine model of biliary atresia, we identified 14 miRNAs whose expression was suppressed at the times of duct obstruction and atresia (≥2 fold suppression, P | 0.05, FDR 5%). Next, we obtained 2,216 putative target genes of the 14 miRNAs using in silico target prediction algorithms.

We found sensitivity for the ascertainment of pancreatic and periampullary cancer cases from the hospital data of 87.5% for the 2005-2009 period. The accuracy of hospital coding varied by tumour primary site and histology, with higher sensitivity of case ascertainment for pancreatic (88.6%) and duodenal cancers (87.1%) compared with extrahepatic bile duct and ampullary cancers (78.8%) and with lower sensitivity for extrahepatic cholangiocarcinomas (67.9%). Misclassification of pancreatic and periampullary cancers in the hospital data was often to closely related sites, for example, intrahepatic bile duct carcinoma, or to less specific sites such as cancers of ill-defined or unspecified primary sites. Whereas hospital coders might only have information from a particular admission available, coders at a cancer registry often have multiple sources of information from diagnostic procedures and treatment which can enable more accurate coding of tumour characteristics.. Several aspects of the coverage ...
In the definitive and palliative setting, concurrent chemoradiation leads to a median OS of 2.2- 27 months and 3 y-years survival rates ranging from 6 to 73 months [24]. Local recurrence is the primary site of progression and dose escalation seems to be promising in terms of LC and OS. In a retrospective series using different fractionation regimes, Tao et al. could show that a BED greater than 80.5 Gy correlated with prolonged OS and LC (p = 0.017 and p = 0.04 respectively).These results, could not be reproduced in another retrospective study from Jung et al. [25] who treated patients using SBRT in 1-5 fraction. In his study a BED higher than 86 Gy did not correlate with better LC or survival (p = 0.4 and p = 0.1 respectively) which is in concordance with our findings. Furthermore, Jung et al. did not find any differences between patients treated for IHCCC (n = 33) vs EHCCC (n = 25) (p = 0.54) but they reported in 10% of the patients grade ≥ 3 complications such as duodenal and gastric ...
For cases of inoperable bile duct carcinoma, we perform intraluminal irradiation using an 192iridium wire following endoprostheses implantation. However, the effectiveness of this procedure is uncertain, and may lead to decreased patient quality of life in some cases. Therefore, we obtained samples of bile duct carcinoma either by percutaneous transhepatic cholangioscope (PTCS) or by surgery, and studied whether expression levels of Ki-67 and p53 in these tissues could predict the effectiveness of radiotherapy (RT). Immunohistochemistry was used to determine the expression of p53 and Ki-67 in 40 resected and 18 biopsy specimens. All biopsy specimens were stage IVA according to UICC classification. Labeling indices were calculated as percentage of positively stained tumor cell nuclei of total tumor cells counted. Samples were divided into two groups according to labeling index (LI). In the resected specimens, Ki-67 LI was significantly higher in cases positive for lymphatic invasion than in ...
Bile duct cancer information with its causes along with various treatments available. A parasitic infection called the liver fluke is known to be responsible for causing the bile duct cancer. Detailed description of bile duct cancer symptoms also given.
Anatomy. Bile canaliculi in the liver combine to form the hepatic ducts. The number of hepatic ducts varies from 3-5; they join the extrahepatic biliary system at the cystic duct. The gallbladder lies in the right medial and quadrate liver lobes in the gallbladder fossa. One duct, the cystic duct, leaves the gallbladder and receives the hepatic ducts. After the last hepatic duct has joined the cystic duct, the duct travelling towards the duodenum becomes the bile duct or common bile duct. The common bile duct enters the duodenum on the major duodenal papilla. The bile duct tunnels submucosally aboral to the serosal attachment of the duct; this is more pronounced in dogs than cats. The gallbladder wall contains smooth muscle and the bladder is lined with epithelium, which is rich in mucous-secreting goblet cells.. Diagnostic Imaging. 1. Radiography. Plain film radiography can demonstrate radiodense choleliths. In addition, focal or generalised peritonitis can be suspected when poor abdominal ...

Choledochal Cyst: A congenital anatomic malformation of a bile duct, including cystic dilatation of the extrahepatic bile duct or the large intrahepatic bile duct. Classification is based on the site and type of dilatation. Type I is most common.
Predominantly extrahepatic bile duct which is formed by the junction of the right and left hepatic ducts, which are predominantly intrahepatic, and, in turn, joins the cystic duct to form the common bile duct.
All the patients undergoing LC between June 2012 and July 2013 were asked to participate in this institutional review board (IRB) approved study. Fluoroscopic and fluorescent cholangiographies were performed to delineate the extrahepatic biliary ducts. For the FC a single dose of 0.05 mg/kg of indocyanine green (ICG) was administered intravenously one hour prior to surgery. During the procedure, alternate exposure from xenon to infrared lights was used to identify the biliary structures before and after dissection. A questionnaire to assess the surgeons visibility of extrahepatic bile ducts was administered.. Results ...

The benefit of adjuvant radiotherapy (ART) for extrahepatic cholangiocarcinoma (EHCC) and gallbladder carcinoma (GBC) is unclear, with conflicting results from nonrandomized studies. We reported a meta-analysis to determine the impact of adjuvant radiotherapy on survival. PubMed, EMBASE, Cochrane Library and CNKI databases were searched to identify clinical trials of postoperative ART versus no radiotherapy for EHCC and GBC. The obtained data were analyzed using RevMan 5.3 and Stata 14.0 statistical software. Differences between two groups were estimated by calculating the odds ratio (OR) and 95% confidence interval (CI). A total of 21 clinical trials involving 1465 EHCC and GBC patients were selected according to the inclusion and exclusion criteria and included in this meta-analysis. The meta-analysis showed the following: The 5-year overall survival (OS) rate was higher in the ART group than in the no radiotherapy group (OR = 0.63; 95% CI = 0.50-0.81, p = 0.0002). The 5-year OS rate was significantly
Our previous studies have demonstrated that up-regulated lung cancer 10 (URLC10) has been identified as a new target of tumor associated antigen using cDNA microarray technique combined with the expression profiles of normal and cancer tissues. We have also found that 100% of tissue samples from bile duct cancer express URLC10. We have determined the HLA-A*2402 and HLA-A*0201 restricted epitope peptides derived from URLC10.These epitope peptides have shown to induce specific Cytotoxic T Lymphocytes (CTL). Furthermore, 60% and 20% of Japanese population have HLA-A*2402 and HLA-A*0201, respectively. Therefore, these peptides are suitable for clinical trial. On the other hand, gemcitabine is a drug approved against bile duct cancer. Recent studies has reported that gemcitabine has an additional ability to improve immune response. From these results, synergistic effect between vaccine therapy and chemotherapy using gemcitabine will be expected.. In this clinical trial, we evaluate the safety, ...
