Active clinical trials for "Nervous System Neoplasms"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combining temozolomide and O6-benzylguanine in treating children who have solid tumors that have not responded to previous therapy.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as pentoxifylline and hydroxyurea may make tumor cells more sensitive to radiation therapy. PURPOSE: Phase I trial to study the effectiveness of radiation therapy plus pentoxifylline and hydroxyurea in treating patients who have high-grade astrocytoma or glioblastoma.

RATIONALE: Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as temozolomide and carmustine, work in different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether erlotinib is more effective than temozolomide or carmustine in treating recurrent glioblastoma multiforme. PURPOSE: This randomized phase II trial is studying erlotinib to see how well it works compared to temozolomide or carmustine in treating patients with recurrent glioblastoma multiforme.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of efaproxiral when given with carmustine and to see how well they work in treating patients with progressive or recurrent malignant glioma.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of temozolomide when given with peripheral stem cell transplantation and to see how well they work in treating children with newly diagnosed malignant glioma or recurrent CNS tumors or other solid tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one chemotherapy drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy following radiation therapy in treating patients who have malignant glioma.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy alone is as effective as chemotherapy plus radiation therapy in treating germ cell tumor. PURPOSE: This randomized phase III trial is studying radiation therapy alone to see how well it works compared to chemotherapy and radiation therapy in treating patients with newly diagnosed primary CNS germ cell tumor.

RATIONALE: Everolimus may stop the growth of tumor cells by stopping blood flow to the tumor. Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Combining everolimus with gefitinib may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with gefitinib and to see how well they work in treating patients with progressive glioblastoma multiforme or (progressive metastatic prostate cancer closed to accrual 10/19/06).

Primary malignant and non-malignant brain tumors account for an estimated 21.42 cases per 100,000 for a total count of 343,175 incident tumors based on worldwide population estimates [1]. These entities result in variable but disappointing rates of survival, particularly for primary brain tumors (5-year survival rates: anaplastic astrocytoma 27%; glioblastoma multiforme 5%) [2, 3]. Metastatic brain tumors outnumber primary brain tumors (estimates as high as 10:1) as they affect approximately 25% of patients diagnosed with cancer [4-6]. In terms of brain tumor surgery, the extent of surgical resection-a factor that is greatly impacted by a Neurosurgeon's ability to visualize these tumors-is directly associated with patient outcomes and survival [7-9]. Although spinal cord tumors are lower in terms of their incidence [10], data correlating extent-of-resection to outcomes and survival have been demonstrated in patients with intramedullary tumors [11]. Using systemically delivered compounds with a high sensitivity of detection by near-infrared (NIR) fluorescence, it would be possible for us to improve surgical resection thus minimizing chances of recurrence and improving survival. Simply, if the tumor cells will "glow" during surgery, the surgeons are more likely to identify tumor margins and residual disease, and are, therefore more likely to perform a superior cancer operation. By ensuring a negative margin through NIR imagery, it would make it possible to decrease the rates of recurrence and thus improve overall survival. This concept of intraoperative molecular imaging requires two innovations: (i) a fluorescent contrast agent that can be injected systemically into the subject and that selectively accumulates in the tumor tissues, and (ii) an imaging system that can detect and quantify the contrast agent in the tumor tissues.[12, 13] Subjects undergo intraoperative imaging, receiving an injection of indocyanine green and then undergoing intraoperative imaging of the surgery site with a NIR imaging system. The imaging devices allow the operating field to be observed in real-time.

The aim of this study is to follow up with all of the pediatric brain tumor patients who received proton beam radiation therapy at Massachusetts General Hospital (MGH) for which there is baseline neuropsychological testing in order to measure changes, if any, in neurobehavioral functioning (executive skills, emotional/behavioral functioning, and adaptive abilities) and their use of special education services at one year or more post-treatment. The investigators will also correlate neurobehavioral data with pertinent clinical information. Participation will be maximized through the use of mail-in, parental- and self-report questionnaires.
