Active clinical trials for "Carcinoma, Islet Cell"

RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with neuroendocrine tumor that is metastatic or unlikely to respond to surgery or radiation therapy.

RATIONALE: Vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stopping blood flow to the tumor. Octreotide may help control symptoms, such as diarrhea, caused by the tumor. Giving vatalanib together with octreotide may be an effective treatment for neuroendocrine tumors. PURPOSE: This phase II trial is studying how well giving vatalanib together with octreotide works in treating patients with progressive neuroendocrine tumors.

This phase II trial studies how well dovitinib lactate works in treating patients with pancreatic neuroendocrine tumors. Dovitinib lactate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This study is the first randomized, open-label, national, multicenter, phase II study assessing the efficacy and safety of OCLU in subjects with pretreated progressive pancreatic, inoperable, somatostatin receptor positive, well differentiated pancreatic neuroendocrine tumors (WDpNET). Subjects must have experienced documented progression of disease within 1 year prior to the start of the study. The control group of patients receiving Sutent will be used as internal control to assess the hypothesis of 12 months PFS equal to 35% in patients receiving Sutent.

To assess the importance patients place on each of the attributes of value (i.e., outcomes, quality of life [QOL], cost, experience), and how these patients’ views differ depending on the stage of their therapy (pretreatment, preoperative therapy, post-operative, long-term surveillance, recurrence).

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.

Pancreatic cystic lesions (PCLs) comprise of a heterogeneous group of entities that are benign, premalignant or malignant. With increased use of modern imaging techniques in recent years, incidentally discovered PCL have become much more common. However, imaging modalities for characterising PCL is a known clinical uncertainty since imaging is capable of detecting these lesions but may often not be able to distinguish malignant from benign lesions. Incorrect assessment of PCL can lead to fatal consequences because a malignant lesion may not be treated and a benign may be unnecessarily resected. The aim of this study was to assess the performance of endoscopic ultrasound with fine-needle aspiration (EUS-FNA) in the diagnosis of pancreatic cystic lesions compared to cross-sectional imaging modalities (CT/MRI). Our hypothesis is that EUS-FNA has a higher accuracy for diagnosing PCLs compared with cross-sectional imaging.
