Active clinical trials for "Cholangiocarcinoma"

To determine the safety and efficacy of photodynamic therapy with a novel photosensitizer and a flexible laser probe in locally advanced hilar cholangiocarcinoma.

The purpose of this study is to determine whether everolimus is effective in the treatment of patients with advance cholangiocarcinoma.

Cholangiocarcinoma (CCA), cancer of the bile duct, is the first cause of cancer death of the people in the northeast of Thailand. The incidence of CCA in this region is highest not only in the country but in the world. CCA is a slow growing but highly metastatic tumor. At present, there is no standard chemotherapy or effective treatment for CCA. Most of the patients have short survival after diagnosis. Strong evidences from in vitro, animal and clinical studies indicate that vitamin D can prevent and control growth of cancer. Our preclinical studies in CCA cell lines, animal and patient tissue culture indicate that vitamin D effectively reduce growth of CCA. Supplementation of vitamin D to chemotherapeutic drugs enhance drug toxicity and better response. At present, there are several clinical trials in USA on supplementation of vitamin D or its analogs to cancer patients. The side effect or toxicity of using vitamin D supplementation is low, some patients had stable disease and some had good response. The current study is set up a clinical trial phase II of vitamin D (calcitriol) in combination with 5-fluorouracil, Mitomycin C and Leucovorin in an open label-non-randomized study to evaluate the tumor response in patients with advanced intrahepatic cholangiocarcinoma. This study will provide an alternative/effective chemotherapy treatment for CCA patients. Better survival and improved quality of life are also expected.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining gemcitabine, leucovorin, and fluorouracil in treating patients who have locally advanced or metastatic cancer of the pancreas or bile duct.

Cholangiocarcinoma (CCA) is the most common biliary malignancy and the second most common hepatic malignancy after hepatocellular carcinoma (HCC). A majority of the CCA (50-70%) was presented in the area of the biliary duct bifurcation. Recent retrospective study included heterogeneous group of malignant diseases demonstrate that draining more than 50% of was associated with a longer median survival. However, in recent European Society of Gastrointestinal Endoscopy (ESGE) biliary stenting clinical guideline and Asia-Pacific consensus recommendations for endoscopic and interventional management of hilar cholangiocarcinoma (HCCA), whether we should deployment bilateral or unilateral metal stent for patients with HCCA was not clearly recommended due to the absence of randomized controlled trials.

Selective Internal Radiotherapy is superior to Transarterial Chemoembolisation for the treatment of intrahepatic cholangiocellular carcinoma (CCC).

The purpose of this study is to evaluate the feasibility, efficacy and safety of FORFIRINOX in advanced or recurrent extrahepatic cholangiocarcinoma and gallbladder carcinoma.

The purpose of this study is to evaluate the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) of irinotecan, oxaliplatin, 5-fluorouracil and leucovorin compared systemic chemotherapy of gemcitabine and oxaliplatin in patients with unresectable intrahepatic cholangiocarcinoma.

Pancreatic cancer and cholangiocarcinoma are the most common causes of malignant biliary obstruction. They are diseases of increasing incidence and unfavorable prognosis. Only a minority of patients have a localized disease and are indicated for surgery with a chance of long-term survival. Locally advanced and metastatic tumors are treated with palliative chemotherapy or chemoradiotherapy; the results of such treatments are unsatisfactory. The average survival of patients with unresectable disease is 6 months and only 5 - 10 % of patients survive 5 years. Chemotherapy and radiotherapy can be used, however only with a palliative effect. Biliary drainage is an integral part of palliative treatment. Endoscopically or percutaneously placed stents improve quality of life, decrease cholestasis and pruritus, but do not significantly improve survival. Biliary stents get occluded over time, possibly resulting in acute cholangitis and require repeated replacement. Endoluminal biliary photodynamic therapy (PDT) and radiofrequency ablation (RFA), locally active endoscopic methods, have been increasingly used in recent years in palliative treatment of patients with malignant biliary obstruction. In photodynamic therapy, improved survival has been shown in two randomized controlled trials; however the technique suffers from technical complexity, high cost and low availability. In RFA, application of low voltage high frequency current during radiofrequency ablation results in tissue destruction by heat. Its antitumor effect may also be related to systemic changes in antitumor immunity. The use of endoluminal biliary RFA has so far been reported only in small retrospective cohorts of patients. The aim of this randomized study is to compare efficacy of RFA plus stenting to stenting alone in palliative treatment of malignant biliary obstruction with survival as primary outcome. Secondary outcomes are stent patency, immediate and late complications, quality of life and effects on anti-tumor immunity in the RFA group.

TQB2450 is a humanized monoclonal antibody targeting programmed death ligand-1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors.
