Testing the Safety and Effectiveness of Radiation-based Treatment (Lutetium Lu 177 Dotatate) for Metastatic Prostate Cancer That Has Neuroendocrine Cells
This phase II trial studies how well lutetium Lu 177 dotatate works in treating patients with prostate cancer with neuroendocrine differentiation that has spread to other places in the body (metastatic). Neuroendocrine differentiation refers to cells that have traits of both hormone-producing endocrine cells and nerve cells. These cells release hormones into the blood in response to a signal from the nervous system. Hormones are biological substances that circulate through the bloodstream to control the activity of other organs or cells in the body. Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called ...

Testing the Use of Chemotherapy After Surgery for High-Risk Pancreatic Neuroendocrine Tumors
This phase II trial studies the effect of capecitabine and temozolomide after surgery in treating patients with high-risk well-differentiated pancreatic neuroendocrine tumors. Chemotherapy drugs, 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. Giving capecitabine and temozolomide after surgery could prevent or delay the return of cancer in patients with high-risk well-differentiated pancreatic neuroendocrine tumors.

The Ailliance Post-Market Clinical Study
The purpose of this clinical study is to collect performance and safety data for post-market Medtronic devices indicated for cranial and/or spinal indication(s). Subjects are enrolled and followed postoperatively for up to 24 months. The Ailliance clinical study is intended to collect data congruous with routine clinical care practices.

The Assessment of Immune Response in Newly Diagnosed Glioblastoma Patients Treated With Pembrolizumab
To evaluate the short-term and longer-term safety, tolerability, and effectiveness of neoadjuvant and adjuvant Pembrolizumab on top of standard therapy (Stupp protocol) in patients with Glioblastoma Multiforme (GBM). Randomized comparison of safety, tolerability, and clinical efficacy of (1) neoadjuvant and adjuvant Pembrolizumab (on top of Stupp protocol, n=12 patients), (2) neoadjuvant Pembrolizumab (on top of Stupp protocol, n=12 patients), and (3) standard of care (Stupp protocol only, n=12 patients). Immuno-PET examination will be performed before and after surgery in all patients.

The circTeloDIAG: Liquid Biopsy for Glioma Tumor
Gliomas represent the most frequent primary brain tumor, with 2,500 to 3,000 new cases per year in France. Their diagnosis, although highly complex, is essential for determining patient management. While grade I gliomas (infrequent) are curable by surgery or present a slow progression, grades II to IV require heavy treatment (surgery and radio-chemotherapy), and are associated with a prognosis ranging from 10-15 years for grade II to only 15 months for glioblastoma. One of the key processes in glioma oncogenesis is the activation of a telomeric maintenance mechanism (TMM). Two TMMs ensure the maintenance of a telomere size...

The Cognitive-Behavioral Dysfunctions and the Potential of Neuroplasticity in Brain Tumors Patients During Radiotherapy
Primary and secondary brain tumors are a constant challenge for the medicine. Tissue sensitivity to ionizing radiation differs and depends on numerous factors and the same dose of radiation may produce different effects in particular structures of the CNS. It can also affect the surrounding healthy tissues and lead to adverse effects like the cognitive or physical function impairment. One of brain structures most sensitive to ionizing radiation is the limbic system, especially the hippocampus, because it is here that the postnatal neurogenesis takes place via neural stem cells, which are a self-renewing population of precursor cells....

The Cohort for Patient-reported Outcomes, Imaging and Trial Inclusion in Metastatic BRAin Disease (COIMBRA)
The incidence of brain metastases is expected to increase because of better treatments of primary tumours. Novel diagnostic and therapeutic techniques are continuously being developed, all of which need thorough evaluation before they can be implemented in clinical routine. Randomized Controlled Trials are the gold standard to do so, but they have shown many challenges, especially when applied in a cancer setting. .The 'cohort multiple Randomized Controlled Trial (cmRCT)' design is a promising design for multiple (simultaneous) randomized evaluations of experimental interventions, with potential for increased recruitment,...

The CyberChallenge Trial How Much is Too Much - What is the Role of Cyberknife Radiosurgery in Patients With Multiple Brain Metastases?
Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Therapy options for multiple brain metastases may vary and range from stereotactic radiosurgery (SRS), whole-brain radiotherapy (WBRT), chemotherapy, immunotherapy to palliative best supportive care. Especially the efficacy and toxicity of SRS compared to WBRT in patients with extensive brain metastases (>4) is not yet clear but of incremental relevance in this seriously ill cohort with a limited life span. These health-impaired patients might especially profit from a less toxic treatment...

The Effect and Safety of Omitting Preoperative Alpha-adrenergic Blockade for Normotensive Pheochromocytoma
Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors originating from catecholamine producing chromaffin cells in the adrenal medulla and extra-adrenal paraganglia. The overall age-standardized incidence rate is 0.18 per 100,000 person-years in Korea. The definitive treatment of PPGL is surgical excision of tumor. However, surgery is associated with a high risk of perioperative hemodynamic instability (HI). To avoid perioperative HI in patients diagnosed with PPGL, preoperative management including routine use of alpha blockade and volume expansion has been advocated by several guidelines. While...
