Filter by:Patients treated with stereotactic radiotherapy for liver tumors undergo PET/CT using the galactose analogue 18-F-deoxy-galactose (FDGal) before and after radiotherapy. This technique provides volumetric mapping of liver function and it allows quantisation of liver function. The method may be used for selection of patients for stereotactic radiotherapy of liver tumors, for determination of radiation induced liver dysfunction and may be included into the treatment planning process of stereotactic radiotherapy.
The purpose of this study is to determine the rate of progression free survival of patients with inoperable cholangiocarcinoma 6 months after enrollment in the study. The patients are treated with combination chemotherapy supplemented by biological agents panitumumab or bevacizumab.
To test the efficacy of a combination chemotherapy of imatinib and 5-FU in advanced or metastatic cholangiocellular carcinoma.
The purpose of this study is to determine progression-free survival at 12 months for stereotactic body radiotherapy (SBRT) and chemotherapy for unresectable hilar cholangiocarcinoma (CCA). Investigators hope to learn more about neoadjuvant SBRT and chemotherapy for unresectable CCA, and if SBRT followed by chemotherapy can lead to successful liver transplantation. This knowledge is important for this patient group as this disease is a highly lethal malignancy that often presents as unresectable, however surgery or transplantation are the only curative options.
Cholangiocarcinomas (CCCs) are malignant tumors arising from the biliary epithelium. CCCs are characterised by a high mortality and the only curable therapy is complete tumor resection, if feasible, or in some cases liver transplantation. Since surgery for CCC is a procedure associated with a high mortality itself it needs to be ascertained that an accurate preoperative diagnosis has been established. However, it often appears to be difficult to get a preoperative pathological diagnosis, since it is difficult to obtain tumor specimens using cytologic brushings, biopsy forceps, bile aspiration or endoscopic ultrasonography guided-fine needle aspiration. This is reflected by a nearly 100% specificity but low sensitivity rates. The aim of this study is to compare a new method of biliary biopsy using a double-balloon enteroscopy (DBE) forceps to enable a safe and reliable tissue specimen collection within the proximal biliary tract with cytology brushings in patients with suspected malignant proximal biliary strictures.
We hope to determine the importance of different genes (including B receptors) in anthracycline-induced cardiomyopathy. This has important benefits to patients exposed to anthracyclines, as this could help determine whether certain individuals have increased susceptibility to cardiac injury.
PROTOCOL Introduction: The introduction of endoscopic retrograde cholangio-pancreatography (ERCP) and endoscopic sphincterotomy (ES) in 1974 has dramatically changed the treatment of biliary and pancreatic diseases. ES permits transection of Oddi's sphincter, allowing the endoscopist to remove stones and place stents. The main indications for ERCP are: 1. Removal of common bile duct stones 2. Dilation of benign biliary ducts strictures 3. Stent placement in patients with malignancy 4. Acute biliary pancreatitis 5. Removal of stones and dilation of strictures of the main pancreatic duct in patients with chronic pancreatitis and 6. Treatment of biliary fistulae after surgical operations . Complications of ES can be described as early (within one month after ES) and late. Early complications have approximately a 10% incidence and include: 1.acute pancreatitis (5,4%) 2.bleeding (2%) 3.acute cholangitis (1%) 4.acute cholecystitis (0,5%) 5. Perforation and others (1,1%). Late complications are mainly the recurrence of choledocholithiasis (2,5%), narrowing of the previous ES and recurrent acute cholangitis. Furthermore, there is a debate in the literature about late development of cholangiocarcinoma. Carcinogenesis after surgical sphincteroplasty and biliary-enteric anastomosis has been described. Previous studies have shown late development of cholangiocarcinoma after transduodenal sphincteroplasty and biliary-enteric anastomosis for benign disease. The incidence is up to 7% in a twenty-year follow up, while in the general population is approximately 1/ 100.000 . In addition, Tocchi et al showed that the rate of cholangiocarcinoma after transduodenal sphincteroplasty and choledochoduodenal anastomosis is up to 5-7% and after other choledochi-enteric anastomoses approximately 1,9%. It seems that the ablation of sphincter function causes prolonged pancreatobiliary and duodenobiliary reflux. Proteolytic pancreatic enzymes are activated and bacterial intestinal flora colonizes the biliary epithelium, causing recurrent inflammation. Chronic inflammatory irritation may lead to hyperplasia, dysplasia and atypia of epithelium, ultimately inducing carcinogenesis. Eleftheriadis et al, studied changes of the biliary epithelium in patients who underwent choledochi-duodenal anastomosis for benign disease, and hyperplasia of the biliary epithelium was demonstrated. The same results and atypia of biliary epithelium were reported by Kurumado et al, in mice models with choledochi-duodenal anastomosis. Anomalous pancreatobiliary junction and choledochal cysts produce the same histologic alterations of the biliary epithelium. These facts raise a great amount of concern about late development of cancer after ES. Bergman et al in a small trial argues that after ES, the function of the biliary sphincter is permanently lost. On the other hand, Sugiyama et al demonstrated the reduction of pancreatobiliary reflux 1 year after ES. In addition, large population-based studies have shown no causal association between ES and cholangiocarcinoma, but with enough limitations in study design. In conclusion, the long term cytologic changes of the biliary epithelium after ES for benign disease are not well known. During ERCP, brush cytology can be performed to evaluate bile duct strictures. The use of endoscopic brushing after ES has no reported complications . Objective: To evaluate cytologic alterations of the biliary epithelium after previous endoscopic sphincterotomy for benign disease.
Preoperative biliary drainage methods include percutaneous transhepatic biliary drainage (PTBD), endoscopic nasobiliary drainage (ENBD), and endoscopic retrograde biliary drainage (ERBD). Endoscopic biliary drainages often induce peritumoral inflammation and it increase difficulties in determining a proper resection margin. The purpose of this study is to compare the clinicopathological outcomes according to the methods of preoperative biliary drainage in periampullary cancers causing obstructive jaundice, and to find out a proper biliary drainage method.
This phase II trial is studying how well giving sorafenib tosylate together with erlotinib hydrochloride works in treating patients with locally advanced, unresectable, or metastatic gallbladder cancer or cholangiocarcinoma. Sorafenib tosylate and erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.
OBJECTIVES Primary objective: The primary objective of the trial is to determine the safety of adjuvant treatment with cisplatin plus gemcitabine for a period of 6 months after curative resection of cholangiocellular carcinoma Secondary objectives: Secondary objectives of the trial are to assess the feasibility and efficacy of the adjuvant therapy and to determine duration of response and patterns of failure compared to historical controls without postoperative treatment Exploratory objectives: To obtain blood samples and tumor tissue after resection for establishment and characterization of new cholangiocarcinoma cell lines and tumor antigens. Other aims are identification of tumor specific antibodies from blood samples, and characterization of tumor antigens with consecutive development of new specific immunological therapies, e.g. cancer-testis antigens (CTA) for tumor vaccination. - Trial with medicinal product
