Evaluation of MRI Sequences for Ultra-rapid Acquisition of Bile Ducts Images
GallstoneCholangitis3 moreThe Institute of Imaged-Guided Surgery (IHU Strasbourg) has two clinical Magnetic Resonance Imaging (MRI) scanners, one with a 3T (3 Teslas) magnetic field used for diagnosis, the other with a magnetic field of 1,5T (1,5 Teslas) used for the interventional (Pre / per / postoperative). The reference for the visualization of the biliary and pancreatic ducts is a relatively long sequence that needs a breathing-synchronized acquisition leading to artefacts on the images (blur effect). In order to reduce and/or standardize the acquisition time as well as to limit artefacts, accelerated sequences are developed. Such sequence is available in France recently in the form of WIP Siemens (Work In Progress: sequence in test phase at manufacturer to be marketed in the short or medium term on clinical machines). It incorporates a Compressed Sensing (CS) acquisition scheme allowing the acquisition of a 3D (3 dimensions) sequence similar to the usual sequence by drastically reducing the acquisition time, the sequence CS-SPACE. This sequence exists in two forms: An ultra-rapid sequence acquired in apnea An accelerated sequence but remaining synchronized with the breath. The study carried out here on a large number of patients, with two different magnetic fields, applied routinely for diagnosis or anticipation of surgery, could be used by the community of radiologists, hepatogastroenterologists and also digestive surgeons Hepatobiliary.

Efficacy of Intraductal Radiofrequency Ablation in Combination With Metallic Biliary Stenting in...
Hilar CholangiocarcinomaBiliary ObstructionThe study aim to evaluate the efficacy of intraductal radiofrequency ablation for unresetable hilar cholangiocarcinoma in addition to biliary stenting. The patient would be randomized into 1:1 ratio of conventional group who received biliary stenting alone, and RFA group who receive intraductal RFA before biliary stenting. Immediate complications as well as long term stent patency and patient survival would be studied.
RFA Combined With Chemotherapy for Unresectable Cholangiocarcinoma
CholangiocarcinomaExtrahepatic cholangiocarcinoma is a malignant tumor that is highly malignant and difficult to diagnose and treat early. Endobiliary radiofrequency ablation (RFA) has been reported to be a beneficial treatment option for palliation of malignant biliary strictures. Within the bile duct, RFA appears to be safe and may result in decreased tumor ingrowth. To date, little is known about the role of the addition of systemic chemotherapy to RFA for cholangiocarcinoma. The aim of this study is to compare the efficacy and safety of RAF combined with Gemcitabine and S-1 in patients with unresectable cholangiocarcinoma.

Bladder CancerPancreas Cancer1 moreThis multicenter, non-randomized, Phase II study will assess the efficacy, safety, and pharmacokinetics of trastuzumab emtansine in participants with HER2 overexpressing locally advanced (unresectable and not treatable with curative intent) or metastatic urothelial bladder cancer (UBC), locally advanced (unresectable and not treatable with curative intent) or metastatic pancreatic cancer/cholangiocarcinoma with advanced disease where cure is no longer possible and where no other treatment options are available anymore. Participants will receive intravenous (IV) infusion of trastuzumab emtansine as Regimen A (2.4 milligrams per kilogram [mg/kg], weekly [qw]) or Regimen B (3.6 mg/kg, every 3 weeks [q3w]) until unacceptable toxicity, withdrawal of consent, disease progression (PD), or death, whichever occurs first. Based on tolerability and safety aspects, steering committee and Independent Data Monitoring Committee (iDMC) will decide on expansion of the study to include more participants with other carcinoma types.
Stereotactic Body Radiation Therapy for Unresectable Perihilar Cholangiocarcinoma
Klatskin TumorRationale: For patients with perihilar cholangiocarcinoma, surgery is the only treatment modality that can result in cure. Unfortunately, in the majority of these patients the tumors are found to be unresectable at presentation due to local invasive tumor growth or the presence of distal metastases. For patients with unresectable cholangiocarcinoma palliative chemotherapy is the standard treatment yielding an estimated median overall survival of 12-15.2 months. There is no evidence from randomized trials that support the routine use of stereotactic body radiation therapy (SBRT) for cholangiocarcinoma. However, small and most often retrospective studies combining chemotherapy with SBRT showed promising results with overall survival reaching up to 33-35 months. Based upon these observations, the investigators designed a local feasibility trial with SBRT after chemotherapy in patients with unresectable perihilar cholangiocarcinoma in order to try to confirm the observed tolerability of adding SBRT to standard chemotherapy. The expected time to include the required patients for this pilot study will be one year. Objective: To assess feasibility of SBRT as add on treatment after standard chemotherapy. Study design: Local feasibility trial. Study population: Patients diagnosed with perihilar cholangiocarcinoma, 18 years of age or older, T1-4 N0-1 M0 (AJCC 7th Edition), after completion of standard chemotherapy. Exclusion criteria are local tumor growth into either stomach, colon, duodenum, pancreas or abdominal wall. Sample size will be 6 patients. Intervention: SBRT will be delivered in 15 fractions of 3 to 4.5Gy after 8 cycles of chemotherapy. In case of toxicity causing premature termination of systemic treatment, the patient can still proceed to SBRT. Main study parameters/endpoints: The primary endpoint of this study is feasibility measured by radiotherapy induced toxicity according to CTC v4.0.3. Secondary endpoints will be: Quality of life Local progression Progression free survival Overall survival Cellular radiosensitivity.
Safety and Efficacy of Modified Folfirinox Versus Gemcis in Bile Duct Tumours
Bile Duct CancerBile duct tumours are rare. They are the 6th most common type of digestive cancer. Their therapeutic management is complex and must be multidisciplinary in nature. Most of the time, an endoscopic or radiological biliary drainage is necessary before any tumour treatment. Their prognosis is poor due to the fact that they are normally diagnosed late, which makes curative surgery impossible. A population study in the Côte d'Or region of France reported a survival rate at 5 years of approximately 10%. For the locally advanced or metastatic forms, treatment has not been properly codified. With respect to chemotherapy, prospective studies, most often phase II, are difficult to interpret due to a limited number of patients and due to the heterogeneity of this type of tumour (bile duct and pancreas tumours). Treatment with 5FU alone provides an objective response in approximately 10% of cases. In combination with mitomycin or carboplatin, the objective response rate is 20%, with a median survival period of 5 months. Interferon combined with 5FU has a better response rate (30%), but occurrences of different types of toxicity are more frequent. More recently, gemcitabine and the 5FU-cisplatin combinations demonstrated objective tumour control in 50% of patients with a median survival period of 10 months. Gemcitabine combined with oxiplatin or with cisplatin has shown the same response rate but a median survival period of approximately 12 months. The benefit of this combination has been confirmed in a phase III trial that compared the gemcitabine-cisplatin combination to gemcitabine alone, in 410 patients with locally advanced unresectable and/or metastatic bile duct cancer. The results were in favour of the combined treatment with a median survival period of 11.7 months (versus 8.1 months - HR 0.64 [0.52 - 0.80]). This combination is currently the reference first-line treatment.
