Filter by:RATIONALE: Current therapies for adults with recurrent or refractory mixed gliomas provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of adults with recurrent or refractory mixed gliomas. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adults with recurrent or refractory mixed gliomas.
RATIONALE: Current therapies for a brain stem glioma provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of brain stem gliomas. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children (> 6 months of age) and adults with newly-diagnosed or recurrent brain stem gliomas.
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 II trial to study the effectiveness of temozolomide and carmustine in treating patients with anaplastic glioma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of irinotecan in treating patients who have recurrent glioma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of O(6)-benzylguanine given before surgery to patients who have malignant glioma.
A dose escalation scale consisting of 5 dosage levels is being used to determine the maximum tolerated dose (MTD) of SU101. A minimum of 3 and a maximum of 6 patients will be enrolled at each dose level. MTD is defined as the dose level immediately below that at which 2 or more patients exhibit dose limiting toxicity. Each treatment cycle is 21 days. Patients receive a 96 hour continuous IV infusion of SU101 on days 1-4.
The presence of a highly selective blood-brain barrier (BBB) at the level of the brain capillary endothelium prevents chemotherapeutic agents from attaining therapeutic concentrations at the target site. RMP-7 is a synthetic bradykinin analog which specifically binds to B2 receptors expressed on the brain capillary endothelial cells and preferentially increases capillary permeability within CNS tumors. Carboplatin is an anticancer agent with preclinical and clinical antitumor activity against a variety of brain tumors. A pediatric phase I trial of the combination of RMP-7 and carboplatin will be conducted to determine the maximum tolerated dose of RMP-7 in children with refractory brain tumors.
Presently, patients with primary malignant brain tumors have a life expectancy of 15 weeks following surgery unless they receive additional types of therapy (chemotherapy, radiotherapy, and/or immunotherapy). Patients that receive additional therapy can increase life expectancy to 50 weeks. The statistics on the life expectancy and survival have increased efforts among researchers to develop new treatments for primary malignant brain tumors. This research project involves the growth and study of human brain tumor cells outside the body in the laboratory as part of an attempt to better understand these tumors and to develop more effective treatments for them.
Glioblastomas, the most frequent malignant brain tumor in adults, are widespread in the brain, despite their discrete appearance on computed tomography (CT) or magnetic resonance imaging (MRI). While this tumor tends to spread widely in the brain, unlike other tumors of the body, it rarely metastasizes, or spreads, to other organs. Approximately 10 percent of patients with glioblastoma develop metastatic disease after radiation or brain surgery. In the absence of radiation or brain surgery, few patients have developed disease spread outside the brain. During surgery to remove tumors of other organs of the body, such as the lung, prostate, kidney, or ovary, cells from these tumors are routinely found in the bloodstream. These cells are believed to be the reason for the spread of these tumors. In the case of malignant brain tumors, this process of glioma (tumor) cells shedding into circulation has not yet been investigated. This study will determine whether glioma cells can be detected in the bloodstream of patients undergoing surgery. If glioma cells are absent, it may mean they are unable to penetrate the blood-brain barrier. If they are present, they presumably can penetrate into blood vessels but they may be recognized and eliminated by the immune system, or they may escape detection yet not be able to take hold in the new microenvironment. The results of the study will add to the knowledge of the biology of these highly malignant tumors. Study participants will be admitted to the hospital for 8 to 10 days. They will undergo a complete physical and neurological exam and blood and urine tests. An electrocardiogram will be performed, and x-rays may be taken. On the morning of surgery, the patient will receive sedation intravenously. A tiny plastic tube called a catheter will be introduced into a vein in the groin through needles. The catheter will be passed through to the jugular bulb, right above the jugular vein, on the same side as the tumor. The patient will then be taken to the operating room for surgery. During surgery, not more than one quarter of a unit of blood will be removed through the catheter. The catheter will be removed before the patient enters the intensive care unit. Another MRI will be taken after surgery. The study will enroll participants for 2 years. Patients will be followed at 3 months and 6 months after the surgery to make sure the postoperative period is uneventful.
