Filter by:The goal of this proposal is to produce and test high specific activity Ultratrace iobenguane I 123 in normal human volunteers.
Intrapatient dose escalation of desipramine. Start at 75 mg daily. Increase by 75 mg weekly to maximum of 450 mg daily. Taper desipramine upon disease progression, unacceptable toxicity or patient withdrawal from study.
Determine wether 24 months treatment with everolimus prolongs progression free survival rate (based on a central assessment) after embolisation ou chemoembolisation for liver metastases. - H0 a 24 months progression free survival rate less than 35% is unacceptable - H1 a 24 months progression free survival rate greater than 35% would show that everolimus treatment is beneficial, the expected 24 months progression free survival rate being 50%
The diagnostic work-up of patients suspected of having neuroendocrine tumours (NETs) has traditionally been a challenging issue. The last two decades have been marked by the application to use in the diagnosis of NETs of 3 newly available diagnostic techniques: endoscopic ultrasonography (EUS), multidetector CT (MDCT), and more recently, positron emission tomography using 68Ga-labelled octreotide analogues (PET). In a prospective study conducted at a single referral centre that compared PET with conventional somatostatin receptor scintigraphy and MDCT in diagnosis, staging and follow-up of patients affected by NET, PET detected more primary and secondary lesions than other methods. Recent studies investigated the clinical impact of PET in the management of patients affected by NET, previously studied by MDCT. The investigators recently reported the results of the investigation of 19 patients suspected of having primary pancreatic NET and studied by PET, MDCT and EUS. The investigators preliminary data suggest that PET may be slightly more sensitive than MDCT in detecting small (<2cm) pancreatic lesions; accuracy of PET and EUS is probably similar. No prospective study has yet been devoted to evaluate the accuracy of PET in the diagnosis and staging of primary duodenal-pancreatic NETs. Furthermore, the clinical impact of the adjunct of PET to the traditional protocols of diagnosis and staging of these tumours waits to be thoroughly evaluated. Thus the appropriate place of PET in the diagnostic algorithm of patients suspected of having duodenal-pancreatic NET remains undefined. The main aim of this project is to prospectively compare the accuracy of PET and MDCT in the diagnosis and staging of patients suspected of having duodenal-pancreatic NETs. The investigators hypothesised that PET is superior to MDCT in the diagnosis of these neoplasm (the dimension of the study sample is estimated in order to detect a 10% difference). The impact of PET on management plan of affected patients will also be evaluated. As a secondary endpoint of the study, the investigators will compare EUS, PET and MDCT in the diagnosis of primary duodenal-pancreatic NET. The study is designed as a multicentre, prospective, non-randomised clinical trial. All patients will undergo MDCT, PET and EUS in this fixed order.
This is a Phase II study in 2 stages, evaluating BEZ235 plus best supportive care (BSC) versus placebo plus BSC in patients with advanced pancreatic neuroendocrine tumors (pNET) after failure of mTOR inhibitor therapy.
The purpose of this study is to explore the efficacy and safety of everolimus administered as a first-line treatment in newly-diagnosed patients with advanced or inoperable Gastrointestinal (GI) or pancreatic neuroendocrine tumors.
This phase I trial studies the side effects and best dose of romidepsin in treating patients with lymphoma, chronic lymphocytic leukemia, or solid tumors with liver dysfunction. Romidepsin may stop the growth of cancer cells by entering the cancer cells and by blocking the activity of proteins that are important for the cancer's growth and survival.
This study will estimate the treatment effect of BEZ235 relative to everolimus on progression-free survival (PFS) in patients with advanced progressive pancreatic neuroendocrine tumors.
This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.
Sunitinib and everolimus are two new treatments approved in 2011 for patients with pancreatic neuroendocrine tumors (NETs). In addition, some traditional chemotherapies are often used to treat pancreatic NETs. Traditional chemotherapy is also known as "cytotoxic therapy" and works by killing cells that are actively dividing. There have been no studies to compare the different types of treatment. Since the patient is eligible for treatment with either sunitinib, everolimus or traditional chemotherapy it can help us identify factors that may help future patients benefit from these therapies.
