NCT00026884
Selected individuals suspected of having or with prior biopsy proof of malignant disease will be seen in the Urologic Oncology Branch, NCI. Blood samples may be collected at the time of the initial visit and at periodic intervals during the course of the disease. These samples will be stored in the tissue bank of the Urologic Oncology Branch. Aliquots of malignant and normal tissue will be collected at the time of surgery and stored in the tissue bank, Urologic Oncology Branch, NCI. These materials will be used in the research efforts of the Urologic Oncology Branch, NCI....
NCT05079334
Investigators from Vanderbilt University Medical Center (VUMC), Duke University, and Meharry Medical College (MMC) are collaborating on a family health history study to deploy a family health history (FHH) platform, MeTree. Recruited participants will complete surveys, the MeTree questionnaire, and MeTree will determine the participant's cancer risk based on current guidelines. The study team will offer genetic counseling to high-risk participants. Investigators will track participant outcomes and behaviors from the use of MeTree to determine the efficiency of the use of MeTree compared to completion of pedigrees in clinic.
NCT03108131
This phase II trial studies how well cobimetinib and atezolizumab work in treating participants with rare tumors that have spread to other places in the body (advanced) or that does not respond to treatment (refractory). Cobimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cobimetinib and atezolizumab may work better in treating participants with advanced or refractory rare tumors.
NCT06915103
This case illustrates the clinical, radiologic, and histopathologic features of Anti-NMDAR encephalitis and underscores the importance of MRI in detecting ovarian teratomas when pelvic ultrasound is inconclusive.
NCT05645185
Paraneoplastic neurological syndromes (PNS) are rare complications of cancer occurring in 0.01% of cases. Their clinical, biological and radiological presentation is heterogeneous and may constitute a diagnostic challenge. Anti-Ma2 PNS are rare diseases with a guarded prognosis. They are most often associated with a seminoma-like testicular tumor but can also be associated with lung cancer. Classically, they present as limbic, diencephalic and/or brainstem encephalitis. Anti-Ma2 antibodies target intracellular receptors and are characteristic of a particular form of encephalitis. Atypical manifestations including narcolepsy-cataplexy, weight gain, sexual dysfunction and motor neuron syndrome have been described and explain the difficulty in diagnosing anti-Ma2 associated PNS. It seems interesting to better characterize the phenotypes of Ma2 patients in order to optimize the diagnosis and follow-up.
NCT04903782
Assessment of the utility of family-based (trio) whole-genome sequencing for cancer predisposition testing in sequential newly diagnosed paediatric and adolescent cancer patients
NCT04653571
Auto-immune encephalitides involve auto-antibodies targeting the central nervous system, and particularly the synapse and its structure, such as protein CASPR2. CASPR2 antibody-associated auto-immune encephalitides lead to an inflammation of the limbic system and generate focal temporal seizures and cognitive impairment. Most patients are initially hospitalized because of the temporal seizures (Joubert et al., JAMA Neurology 2016). However, many already show at that time cognitive impairment, which has failed to elicit the appropriate investigations, therefore delaying the diagnosis. The study will hence investigate precisely the initial, sometimes neglected, clinical symptoms and those leading to the diagnosis, in the cohort of patients suffering from a CASPR2 antibody-associated encephalitis, from the French reference center on paraneoplastic neurological diseases and autoimmune encephalitis. This way, the study aims to delineate the symptoms that should trigger suspicions of a CASPR2 antibody-associated encephalitis
NCT00327236
The investigators believe that T cells, cells that are a part of the immune system, are what are causing the neurological problems while also attacking tumor cells. This protocol studies the clinical status of patients with paraneoplastic neurological disorder (PND) as well as their blood to understand the relationship between their neurological disease, their cancer, and their immune system.
NCT00433485
RATIONALE: Studying samples of blood and tissue from patients with basal cell nevus syndrome and from healthy participants in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to basal cell nevus syndrome. Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of sirolimus may keep basal cell skin cancer from forming in patients with basal cell nevus syndrome. PURPOSE: This phase I trial is studying topical sirolimus in patients with basal cell nevus syndrome and in healthy participants.
NCT00002947
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of indium In 111 pentetreotide in treating patients who have refractory cancer.
NCT00454376
RATIONALE: Questionnaires that measure quality of life may help doctors identify the effects of treatment and improve the ability to plan treatment for patients with gastrointestinal-related neuroendocrine tumors. PURPOSE: This phase IV clinical trial is studying how well a disease-specific questionnaire works in assessing the quality of life of patients with gastrointestinal-related neuroendocrine tumors.
NCT00001496
Women who are at high risk for breast cancer, either because of linkage to high risk breast and ovarian cancer families, or because of a carcinoma in the opposite breast, will be studied. Women will have a physical examination and mammography to ensure that no breast abnormalities are present. Eligible women will undergo biopsy of the breast to obtain normal breast tissue. Short-term cell cultures will be established from this tissue and early passages of the short-term cell lines will be stored. A bank of high risk normal mammary epithelial cells will be established. To further characterize the mammary epithelial cells in this population of women, cell cultures will subsequently be analyzed for their growth and metabolic properties, sensitivity to chemopreventive agents, steroid receptor characteristics, oncogene expression and regulation, and genetic changes.
