Filter by:The purpose of this prospective study is to compare the diagnostic utility of two techniques (brush cytology + FISH and brush cytology + free DNA analysis) in the diagnosis of biliary strictures. Histologic diagnosis (biopsies) in conjunction with clinical and/or imaging follow-up will serve as the gold standard for diagnosis of malignancy. In order to do this the investigators will ask study participants to have a small volume of fluid obtained from the bile duct sent for additional testing at RedPATH. In some patients additional brushings will be obtained for FISH testing (this adds <2 minutes to ERCP and only associated risk is increased procedure duration). The investigators hypothesize that the use of cytology +DNA analysis has a higher sensitivity and accuracy when compared to cytology +FISH in patients with biliary strictures. Primary aim: To compare the sensitivity and accuracy of the two techniques (brush cytology + FISH and brush cytology + free DNA analysis). Histologic diagnosis (histology from biopsy or cytology for fine needle aspiration) in conjunction with clinical and/or imaging follow-up will serve as the gold standard for diagnosis of malignancy. Secondary aims: 1. To evaluate the diagnostic yield of malignancy when all three techniques (cytology, FISH and DNA analysis) are used. 2. To evaluate the added value of biliary forceps biopsies, when used in conjunction with cytology, FISH and DNA analysis.
This phase II study was designed to evaluate the efficacy and safety of S-1 plus Abraxane as second-line treatment for cholangiocarcinoma.
This research study is evaluating a drug called cabozantinib as a possible treatment cancer of the bile duct. Cabozantinib is a drug that targets specific pathways inside the cells of the body. By blocking the c-MET and VEGFR2 pathways from sending signals, cabozantinib may prevent cells from multiplying. This drug has been used in other research studies and information from those other research studies suggests that this drug may help to stop the growth of bile duct cancer. In this research study, the investigators are looking to see how well cabozantinib works in slowing the growth of bile duct cancer. The investigators are also assessing the safety and tolerability of cabozantinib in participants with this type of cancer.
This is a Phase I study, which means we want to find out what effects, good and/or bad, this combination of drugs may have on the patient and the liver cancer at different dose levels. All patients will have an operation to remove tumors in the liver and may have a pump placed in their abdomen. On this study, both drugs given have been used in other patients for treatment of cholangiocarcinoma and other gastrointestinal cancers. Both drugs are approved by the food and drug administration (FDA) for treatment of liver cancer, but the two drugs have only been combined in a few patients. That means that in this trial we also want to find out if this combination is safe. The study will also evaluate if this treatment works in delaying or stopping the cancer from coming back after surgery.
The purpose of this study is to determine whether fit patients (with ECOG performance score of 0-1) with advanced biliary tract cancer (ABC) benefit from chemotherapy in the second-line setting (after prior therapy with cisplatin and gemcitabine) in terms of overall survival.
Cholangiocarcinoma is a rare and very aggressive neoplasm that arises from the biliary epithelium, constitutes approximately 2% of all reported cancer, and accounts for about 3% of all gastrointestinal malignancies. Up to date, there are many modalities to diagnosis and treat with a range of sensitivity and specificity, and also the advantage and disadvantage of its modality. Cholangiocarcinoma has a poor prognosis. Surgical resection offers the only curative option and usually requires a major hepatic resection in addition to resection of the cholangiocarcinoma. Unfortunately, curative resection is possible in only about 30% of patients due to locally advanced disease, distant metastases or comorbidity in elderly patients. Even after resection, the recurrence rate is approximately 60%, resulting in a low 5-year overall survival (OS). Patients with intra-hepatic Cholangiocarcinoma (ICC) have a very limited benefit from systemic chemotherapy, indeed, in unresectable cholangiocarcinoma Overall Survival with systemic chemotherapy is less than 1 year. Since most cholangiocarcinoma patients develop distant metastases at late stages only, locoregional therapy is an interesting therapeutic strategy. Locoregional therapy studies in patients with intrahepatic cholangiocarcinoma employing radiofrequency ablation (RFA), transarterial chemoembolization (TACE) or external as well as internal radiation therapy yielded promising results in the last couple of years. TACE is safe and may be effective for prolonging the survival of patients with nonresectable combined hepatocellular carcinoma (HCC) -cholangiocarcinoma, as compared with the historically reported survivals of these patients. Tumor vascularity is highly associated with tumor response. The patient survival period after TACE for combined HCC-cholangiocarcinoma is significantly dependent on tumor size, tumor vascularity, Child-Pugh class, and presence or absence of portal vein invasion. Currently, few centers perform TACE therapy for unresectable Cholangiocarcinoma. Several European studies have reported the efficacy and safety TACE for ICC. The establishment of a registry to obtain the majority of Cholangiocarcinoma cases treated with locoregional approach within and outside Europe can help the investigators evaluate a larger and non-ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of TACE for ICC.
The investigators study the VEGF signaling in ICC cell lines／human tissues and its mechanism in HCC growth, proliferation and apoptosis.
Background: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: - Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. - Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: - Before their procedure, participants will have a small blood sample taken. - Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. - For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. - Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.
The purpose of this study is to confirm that prognosis of Intrahepatic Cholangiocarcinoma (ICC) with resection and radiotherapy ,to find which is safe and effective treatment.
The purpose of this study is to assess efficacy and tolerance of intra-hepatic administration of Yttrium 90-labelled microsphere (Theraspheres®, Nordion) in association with intravenous chemotherapy with Gemcitabin and Cisplatin for the treatment of intra-hepatic cholangiocarcinoma.
