Filter by:Primary sclerosing cholangitis (PSC) is a chronic inflammatory condition of the bile ducts of unknown etiology. It is characterized by diffuse inflammation and stricturing of the entire biliary tree, eventually resulting in cirrhosis of the liver. Patients with PSC are at increased risk for the development of cholangiocarcinoma (CCA), a cancer arising from bile duct epithelium. This risk is estimated to be approximately 1 to 1.5% per year. It is postulated that chronic inflammatory changes in the biliary epithelium promote CCA formation. The prognosis of CCA is fatal. The only potentially curative therapy is surgical; however, only a minority of patients qualify for surgical treatment. Several studies have demonstrated overexpression of the epidermal growth factor receptor (EGFR) in CCA cells. EGFR is a type 1 tyrosine kinase promoting cell proliferation, migration and altered cell adhesion - typical characteristics of malignant neoplasias. In CCA cells, EGFR-activation is sustained resulting in cancer progression. In human CCA samples, EGFR-expression correlates with higher histologic grade, poor prognosis, and risk of recurrence. The EGFR gene is located on the short arm of chromosome 7 (7p12). Chromosomal abnormalities of the bile duct epithelium, particularly trisomy 7 (i.e. three copies of chromosome 7) can be detected in biliary epithelial samples obtained by endoscopic retrograde cholangiopancreatography (ERCP) in PSC patients. The finding of cells with trisomy 7 has preceded the development of aneuploidy and multiple chromosomal abnormalities in a number of patients, the latter chromosomal abnormalities are characteristic of CCA. Trisomy 7 amplifies the gene for EGFR thereby presumably promoting overexpression of this growth factor receptor. In a cohort of patients with Trisomy 7 and Primary Sclerosing Cholangitis patients followed for 1 year, the rate of development of Cholangiocarcinoma was 35% (n=37, Dr. Gores, unpublished observation). Patients without cytologic abnormalities were at minimal risk for the development of CCA. Erlotinib (Tarceva) is a human EGFR type 1 tyrosine kinase inhibitor. Tarceva received FDA approval as single agent treatment for patients with locally advanced or metastatic non-small cell lung cancer. In a randomized, double blind, placebo controlled trial of 731 patients, receiving 150 mg of Tarceva or placebo once daily, median survival was prolonged to 6.7 months from 4.7 months (p<0.001). Analysis of epidermal growth factor receptor expression (45% of total study patients) demonstrated greater survival benefit in EGFR positive patients. Tarceva in combination with Gemcitabine is also FDA approved as first line therapy in patients with locally advanced, unresectable or metastatic pancreatic cancer. Our central hypothesis is that patients with trisomy 7 will have carcinogenic changes including EGFR overexpression. EGFR blockade will inhibit a growth/survival advantage for these premalignant clones eliminating them from the biliary epithelium. As an initial step towards testing this hypothesis, the tolerability of Tarceva in this patient population needs to be established. This study will assist in determining the safety and tolerability of Tarceva in patients with primary sclerosing cholangitis. This study will be followed by a Phase 2 randomized controlled trial of Tarceva in patients with Primary Sclerosing Cholangitis with Trisomy 7.
This randomized phase I trial is studying the side effects and best dose of everolimus, gemcitabine hydrochloride, and cisplatin in treating patients with unresectable solid tumors refractory to standard therapy. Drugs used in chemotherapy, such as everolimus, gemcitabine hydrochloride, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells.
This study evaluates the combination chemotherapy with gemcitabine, irinotecan and panitumumab in patients with advanced biliary cancer.
The purpose of this study is to test an investigational combination of drugs for bile duct or gallbladder cancers. Gemcitabine and cisplatin are two forms of chemotherapy commonly used in combination to treat bile duct and gallbladder cancers. We are looking to improve treatment results. We will attempt to do so by adding sorafenib (a type of monoclonal antibody) to your treatment plan. Sorafenib acts by attaching to blocking specific targets on cells. These targets may help the cancer cells grow and divide. This study will help answer the question of whether sorafenib is a helpful drug in patients with bile duct or gallbladder cancers when given with gemcitabine and cisplatin. This study is a phase 2 study. The purpose of a phase 2 study is to find out what effects, good and/or bad, sorafenib in combination with gemcitabine and cisplatin has on advanced bile duct and gallbladder cancers.
In patients with unresectable perihilar cholangiocarcinoma, photodynamic therapy with biliary stent has been known for palliation of jaundice and improving survival. But most of therapeutic effects were expected to delay bile duct obstruction rather than to decrease the tumor. Recently orally available chemotherapeutic agent, S-1 was reported as effective in patients with bile duct adenocarcinoma. The investigators' aims of study evaluate the combined effect of photodynamic therapy and S-1.
RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Specialized radiation therapy, such as yttrium Y 90 glass microspheres that deliver a high dose of radiation directly to the tumor, may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Capecitabine may also make tumor cells more sensitive to radiation therapy. PURPOSE: This phase I trial is studying the side effects and best dose of yttrium Y 90 glass microspheres when given together with capecitabine in treating patients with liver cholangiocarcinoma or liver metastases.

This registry will collect data from patients routinely undergoing an ERCP and Cellvizio endomicroscopy procedure (and optionally an additional cholangiopancreatoscopy procedure) due to suspected pancreatic or bile duct cancer. The objective is to determine if endomicroscopy images collected using the marketed Cellvizio device may help endoscopists more accurately diagnose, in conjunction with traditional tissue sampling techniques, whether a suspected lesion is malignant or benign.
The purpose of this study is partly to continue the good experience the investigators have with chemotherapy and partly to optimize treatment of inoperable cholangiocarcinoma by adding a biological antibody to the treatment of patients with wild-type Kirsten rat sarcoma viral oncogene homolog (KRAS).
The primary objective of the trial is to determine the efficacy of VANDETANIB monotherapy or VANDETANIB plus GEMCITABINE or PLACEBO plus GEMCITABINE in prolonging the progression-free survival (PFS) at the trial closure in patients with advanced (unresectable or metastatic) biliary tract cancer.
