Filter by:The Response Evaluation Criteria in Solid Tumors (RECIST), based on differences in tumor size, has been considered as a reproducible method that facilitates not only the measurement of the mass but the evaluation of response to given treatments; while classic chemotherapy induces a reduction of the tumor, new target therapies frequently produce the stabilization of the disease or a delayed progression. These new therapeutic alternatives have shade light on the limitations of the RECIST criteria, since the response to these type of treatments are basically associated with changes on the radiological characteristics of the tumor, as well as other findings in functional imaging. This study is aimed to compare the response rates according both Choi and RECIST criteria.
Positron emission tomography/computed tomography (PET/CT) is an advanced nuclear medicine scan. This technology allows precise and early cancer to be visualized and measured on whole body images. Patients with Neuro-Endocrine tumors (NETs), require specialized molecular imaging to stage, re-stage and assess eligibility and response to therapy. 68Ga-DOTATATE is a nuclear medicine imaging agent that is not yet approved by Health Canada but used extensively throughout the world. The Ki-67 index, a marker of cell proliferation in NETs, is one of the most important prognostic factors in this disease. The objective of this study is to evaluate if the maximal standard uptake value (SUVmax) on PET/CT in NETs inversely correlates with Ki-67 score on initial biopsy. If this hypothesized correlation between SUV and Ki-67 score is reproduced, then DOTATATE would serve as a non-invasive method to assess cellular proliferation and therefore prognosis of these patients.
Although gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) were considered for years as rare tumors, their incidences are increasing. Due to their potential of early metastases and their heterogenous response to therapy, these tumors are important clinical entities. A major problem remains the impossibility to adequately predict tumors' response to treatment, precluding an individualized therapy. Further, there is no method to efficiently screen these tumors. Protein based analyses (proteomic analyses) gain in interest as methods to address this problematic. The present study was designed to investigate epidemiologic data of patients with GEP-NEN and to answer following questions using proteomic analysis applied to existing pathology specimens (paraffin-embedded specimens, FFPE): is it possible to explore protein signatures in this type of tumors? Is the response to therapy predictable using specific protein signatures? Is the tumor's tendency to metastasize related to specific protein signatures?
This study will evaluate the potential immunomodulatory synergy of the association of metronomic cyclophosphamide (CMC) and interferon-alpha (IFN-alpha).
This phase II trial studies nivolumab and ipilimumab in treating patients with rare tumors. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

This phase I trial studies the side effects and best dose of veliparib when given together with capecitabine and temozolomide in treating patients with neuroendocrine tumor that has spread to other places in the body and usually cannot be cured or controlled with treatment, has returned after a period of improvement, and cannot be removed by surgery. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
Urinary measure of 5-hydroxyindolacetic acid (5HIAA) is an important marker for the diagnosis and follow-up of patients with small-intestine neuroendocrine tumors. Although this marker has good specificity, its sensitivity is moderate and its dosage is constraining, since it requires urine collection over 2-3 days and specific diet. Preliminary data suggested that overnight 5HIAA value may be representative of 24-hour 5HIAA value, and that plasma 5HIAA dosage could be a valuable alternative to urine 5HIAA dosage. The main objective of this study is to compare sensitivity and specificity of overnight 5HIAA value, 24-hour 5HIAA value and plasma 5HIAA value, in patients with small-intestine neuroendocrine tumors.
This is a Pilot, One-arm, Open-label, Prospective Study to evaluate Safety of Lanreotide 120 mg ATG in combination with Metformin in patients with advanced progressive GI or lung carcinoids.
