Filter by:The purpose of this study is to evaluate the utility of the QLQ-GINET21 in making clinical and therapeutic decisions.
To evaluate safety and efficacy of everolimus (Afinitor®) in Chinese adult patients with local advanced or metastatic, well differentiated progressive pancreatic neuroendocrine tumors.
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.
This study will evaluate the potential immunomodulatory synergy of the association of metronomic cyclophosphamide (CMC) and interferon-alpha (IFN-alpha).
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 an observational and exploratory study. Participants will be asked for a blood collection and a 24- hour collection of urine. The indol profile and levels of catecholamine and metabolites in PRP, as well as in 24- hour collection of urine will be measured with LC-MS/MS and analyzed.
Phase-II, prospective, open label, no control group to assess the safety of 68Ga-DOTA-TATE injection in patients with suspected or diagnosed with tumors expressing somatostatin receptors. Each included patient will receive an administered dose of 50 mcg or less of the peptide (DOTA-TATE) and a range of activity between 100 - 200 MBq of 68Ga-DOTA-TATE. The efficacy of 68Ga-DOTA-TATE in assessing this kind of tumors has been proved by numerous studies.
A phase II trial to assess the activity and safety of PD0332991 in patients with well- and moderately-differentiated metastatic pancreatic neuroendocrine tumors (pNET) with overexpression of cell cycle markers (Cdk4 and/or phospho-Rb1 and/or cyclin D1)
Data from this study will contribute additional knowledge regarding patient outcomes and direct somatostatin analogue (SSA) treatment related costs in clinical practice in the Nordic countries. Such knowledge can be of importance in a treatment decision, decision support for development of care, follow up and training of both patients and primary care nurses.
