Active clinical trials for "Pinealoma"

RATIONALE: Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This phase I/II trial is studying the best way to give proton beam radiation therapy and to see how well it works in treating patients with low grade gliomas.

Phase I trial to study the safety of combining O6-benzylguanine with temozolomide in treating children who have recurrent or refractory brain tumors. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. O6-benzylguanine may increase the effectiveness of temozolomide by making tumor cells more sensitive to the drug.

This is an open-label, single-arm, single-center, proof-of-concept study to assess the effects of melatonin on cardiac autonomic activity in melatonin non-proficient pinealectomized patients.

The aim of this observational study is to learn about the role of surgery with its different approaches and modalities in the management of pineal region tumors in pediatric population.the main question it aims to answer is : How can surgery affect the outcome in children with pineal region tumors ?

This randomized phase II trial studies how well giving temozolomide and irinotecan hydrochloride together with or without bevacizumab works in treating young patients with recurrent or refractory medulloblastoma or central nervous system (CNS) primitive neuroectodermal tumors. Drugs used in chemotherapy, such as temozolomide and irinotecan hydrochloride, 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. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether temozolomide and irinotecan hydrochloride are more effective with or without bevacizumab in treating medulloblastoma or CNS primitive neuroectodermal tumors.

This phase I trial is studying the side effects of fluorine F18 EF5 when given during positron emission tomography to find oxygen in tumor cells of patients who are undergoing surgery or biopsy for newly diagnosed brain tumors. Diagnostic procedures using fluorine F 18 EF5 and positron emission tomography to detect tumor hypoxia may help in planning cancer treatment

RATIONALE: Specialized radiation therapy that delivers radiation directly to the area where a tumor was surgically removed may kill any remaining tumor cells and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well proton beam radiation therapy works in treating young patients who have undergone biopsy or surgery for medulloblastoma or pineoblastoma.

This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with recurrent, progressive, or refractory CNS tumors. Lenalidomide may stop the growth of CNS tumors by blocking blood flow to the tumor. It may also stimulate the immune system in different ways and stop tumor cells from growing.

This phase I trial studies the side effects and best dose of gamma-secretase/Notch signalling pathway inhibitor RO4929097 (RO4929097) when given together with temozolomide and radiation therapy in treating patients with newly diagnosed malignant glioma. Enzyme inhibitors, such as gamma-secretase/Notch signalling pathway inhibitor RO4929097, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving gamma-secretase/Notch signalling pathway inhibitor RO4929097 together with temozolomide and radiation therapy may kill more tumor cells.

Children, adolescents and young adults with relapsed or treatment refractory pineoblastoma (rPB) represent a group of patients with dismal prognosis for whom a recommended standard salvage therapy is currently not available.
