Thoracotomy Versus Thoracoscopic Management of Pulmonary Metastases in Patients With Osteosarcoma
Recruiting
This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer. Thoracoscopy is a type of chest surgery where the doctor makes several small incision... Read More

A Study to See if Memantine Protects the Brain During Radiation Therapy Treatment for Primary Central Nervous System Tumors
Recruiting
This phase III trial compares memantine to placebo in treating patients with primary central nervous system tumors. Memantine may block receptors (parts of nerve cells) in the brain known to contribute to a decline in cognitive function. Giving memantine may make a difference in cognitive function (attention, memory, or other thought processes) in children and adolescents receiving brain radiation therapy to treat a primary central nervous system tumors.

A Safety and Dose-finding Study of PRL-02 Depot in Men With Advanced Prostate Cancer
Recruiting
Medicines that reduce the amount of testosterone in the body are commonly used to treat prostate cancer. PRL-02 depot is a potential treatment for men with advanced prostate cancer. It is given by an injection into the muscle. Men with advanced prostate cancer can take part in this study. Their cancer has come back after previous cancer treatment, or the previous cancer treatment they had didn't work. The main aims of the study are: * to check the safety of PRL-02 depot given with and without... Read More

A Study of a New Way to Treat Children and Young Adults With a Brain Tumor Called NGGCT
Recruiting
This phase II trial studies the best approach to combine chemotherapy and radiation therapy (RT) based on the patient's response to induction chemotherapy in patients with non-germinomatous germ cell tumors (NGGCT) that have not spread to other parts of the brain or body (localized). This study has 2 goals: 1) optimizing radiation for patients who respond well to induction chemotherapy to diminish spinal cord relapses, 2) utilizing higher dose chemotherapy followed by conventional RT in patients...

Brain Tumor-Specific Immune Cells (IL13Ralpha2-CAR T Cells) for the Treatment of Leptomeningeal Glioblastoma, Ependymoma, or Medulloblastoma
Recruiting
This phase I trial investigates the side effects of brain tumor-specific immune cells (IL13Ralpha2-CAR T cells) in treating patients with leptomeningeal disease from glioblastoma, ependymoma, or medulloblastoma. Immune cells are part of the immune system and help the body fight infections and other diseases. Immune cells can be engineered to destroy brain tumor cells in the laboratory. IL13Ralpha2-CAR T cells is brain tumor specific and can enter and express its genes in immune cells. Giving IL1... Read More

Bevacizumab Treatment For Type 1 ROP
Recruiting
Type 1 retinopathy of prematurity in zone I represents the most severe type of ROP and has the worst prognosis. It is unknown whether low-dose bevacizumab will be successful in these severe cases. Also unknown is the timing and extent of peripheral retinal vascularization after low-dose bevacizumab compared with the standard dose. The current study will evaluate whether doses of 0.063 mg and 0.25mg are effective as treatment for type 1 ROP, with ROP and retinal vessels all in zone I.
