Nineteen patients with biopsy-proven high-grade astrocytomas received as initial treatment whole-brain radiation and combination chemotherapy with 5-fluorouracil (5-FU), 1,000 mg/m2/24 h as a continuous infusion for 96 h, and bolus cisdiamminedichloroplatinum II (CDDP), 100 mg/m2. Chemotherapy
Twenty patients with astrocytomas recurrent after surgery +/- radiation were treated on a phase II protocol of the new anthracycline derivative menogaril 115 mg/m2 administered intravenously once per week. Sixteen patients were evaluable for treatment efficacy. No patient achieved a major
BACKGROUND
The primary objective of this prospective phase 2 study of CPT-11 in adult patients with recurrent temozolomide-refractory anaplastic astrocytoma (AA) was to evaluate 6-month progression-free survival (PFS).
METHODS
Forty patients (27 men and 13 women) ages 17 to 58 years (median age, 38
BACKGROUND
Clinical studies have shown that temozolomide (TMZ) and irinotecan demonstrate activity in high grade astrocytic tumors (HGAT). However, the optimal schedule of administration is unknown.
METHODS
In the present study, a total of 45 HGAT patients, 38 with glioblastoma multiforme (GBM) and
We evaluated the safety and survival benefits of orally administered erlotinib monotherapy for patients with relapsed/refractory glioblastoma multiforme (GBM) or anaplastic astrocytoma (AA). A dose escalation schedule was administered with a starting dose of 150 mg/day for the first cycle (28 days),
OBJECTIVE
Amplification of the epidermal growth factor receptor (EGFR) gene represents one of the most frequent gene alterations in glioblastoma (GBM). In the current study, we evaluated gefitinib, a potent EGFR inhibitor, in the treatment of adults with newly diagnosed GBM.
METHODS
Ninety-eight
The purpose of this investigation was to assess the toxicity and activity of chronic oral etoposide in the management of children with recurrent juvenile pilocytic cerebellar astrocytomas. Twelve children with recurrent juvenile pilocytic cerebellar astrocytomas, refractory to surgical resection,
BACKGROUND
A long-term regimen of oral etoposide, a type of chemotherapy, is used in oncology and is effective in treating germ-cell tumors, lymphomas, Kaposi sarcoma, and primary brain tumors.
OBJECTIVE
To examine the toxic effects and efficacy of long-term salvage chemotherapy using oral
Despite improvements in neurosurgical and neuroradiotherapeutic techniques, children with malignant brain tumors have a dismal prognosis. In an attempt to improve the efficacy of cytotoxic therapy, dose intensification of effective chemotherapeutic agents followed by autologous bone marrow
Patients with recurrence of high-grade glioma (HGG) after bevacizumab (BEV) have an extremely poor prognosis. Etirinotecan pegol (EP) is the first long-acting topoisomerase-I inhibitor designed to concentrate in and provide continuous tumor exposure throughout the entire chemotherapy cycle. Here we
Pediatric gliosarcoma (GS) is a rare variant of glioblastoma multiforme. The authors describe the case of an unusual pontine location of GS in a 9-year-old boy who was initially diagnosed with low-grade astrocytoma (LGA) that was successfully controlled for 4 years. Subsequently, his brain tumor
BACKGROUND
Glial neoplasms can infiltrate the central nervous system extensively with relative preservation of the underlying neuronal architecture. The differential diagnosis between cerebral glioma and infective lesions can be very difficult to distinguish by MRI only.
METHODS
We report a 7 year
In preclinical studies, BCNU, or 1,3-bis(2-chloroethyl)-1-nitrosourea, plus CPT-11 (irinotecan) exhibits schedule-dependent, synergistic activity against malignant glioma (MG). We previously established the maximum tolerated dose of CPT-11 when administered for 4 consecutive weeks in combination
BACKGROUND
We evaluated the efficacy of imatinib plus hydroxyurea in patients with progressive/recurrent low-grade glioma.
METHODS
A total of 64 patients with recurrent/progressive low-grade glioma were enrolled in this single-center study that stratified patients into astrocytoma and
To evaluate the anticancer agent flavone acetic acid (FAA), we conducted a Phase I trial involving 17 pediatric patients with various malignant solid tumors. Dosages investigated included 5,120 and 6,144 mg/m2 given as 3-hour intravenous infusions; and 10,000, 12,500, 15,000, and 17,500 mg/m2
