PRAME Immunohistochemistry as an Adjunct for Evaluating Ambiguous Melanocytic Proliferation
Skin melanoma is a common form of skin cancer. Its diagnosis is usually clinically suspected and then affirmed by histopathological examination. In some cases, the histopathological analysis of these lesions is equivocal, and the malignant or benign nature of the proliferation is difficult to determine with certainty. In these cases, the use of expensive ancillary tests, which are hardly accessible and take a long time to set up (FISH - CGH-array), is usually required. Anti-PRAME immunostaining, an inexpensive and readily available technic, has recently been described as highly sensitive and specific for diagnosing malignant...

Preoperative PRRT Versus Surgical Cytoreduction in Metastatic Pancreatic Neuroendocrine Tumors to the Liver
Doctors and researchers leading this study hope to learn more about peptide receptor radionuclide therapy (PRRT) in combination with cytoreduction (surgically removing tumors). They hope to learn if combining PRRT in combination with cytoreduction would be more effective than cytoreduction alone. PRRT itself is approved by the U.S. Food and Drug Administration (FDA) for people with PanNETs however the combination with cytoreduction is considered experimental. Your participation in this research will last about 2 years. The purpose of this research is to gather information on the safety and effectiveness of PRRT.

Preoperative Radiosurgery for the Treatment of High Grade Glioma, The NeoGlioma Study
This phase I/IIA trial finds out the possible benefits and/or side effects of radiosurgery before surgery (preoperative) in treating patients with high grade glioma. Radiosurgery uses special equipment to position the patient and precisely give a single large dose of radiation to the tumor. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Giving pre-operative radiosurgery may improve the odds of brain tumor control and reduce treatment-related side effects.

Prevention of Neovascular Glaucoma by Intravitreal Injections of Anti-VEGF in Patients Treated With Proton Therapy for a Large Choroidal Melanoma
The reference treatment of ocular melanoma is a conservative treatment by proton therapy. Its goal is to treat the tumor while preserving the eyeball and visual acuity. However, ablation of the eyeball is sometimes necessary after proton therapy in the case of neovascular glaucoma. This complication occurs in 7 to 47% of cases (depending on the size of the tumor) and is associated with hypersecretion of Vascular Endothelial Growth Factor (VEGF) related to necrotic and inflammatory tumor tissue after proton therapy or ischemic retina. The intravitreal injections of anti-VEGF are used in the treatment of neovascular radicular glaucoma...

Prognostic's Factors of Head and Neck Paragangliomas Evolution
Cervical paragangliomas (HNPG) are rare tumors (0.6% of head and neck tumors) arising from chromaffin tissue, of cervical paraganglia (PGL). The most common locations are carotid body (60% of cases), jugulo-tympanic region and vagal body. More than 30% are proved to occur in a context of genetic predisposition, more often in young people, and genetic screening is recommended in all patients. Multifocal tumors represent 12% of all HNPG and until 50% of familial forms. Most of HNPG are non-secreting, benign and slow growing tumors, but up to 30% present complications of local growth, and up to 10% can develop distant metastasis that...
