Background and objective Postoperative radiotherapy is usually indicated for both grade 3 glioma and grade 4 glioblastoma. However, the treatment results and tumor features of grade 3 glioma clearly differ from those of glioblastoma. There is limited

Tumor sphere-forming (TS) glioma stem cells and cancerous TS cells were analyzed in vivo and in vitro. The boron concentration in murine TS tumors was higher than normal tissue. The boron concentration at 24 h was 0.80 ± 0.09 μg/107 in the TS cells

Background Carmustine (BCNU) wafer (Gliadel(®) Wafer) implantation after tumor resection is an approved treatment for high-grade glioma (HGG). These wafers change various characteristics on early postoperative magnetic resonance imaging (ep-MRI) inc

We evaluated the feasibility of 5-aminolevulinic acid (5-ALA)-mediated photodynamic diagnosis (PDD) in the biopsy for primary central nervous system lymphoma (PCNSL). 5-ALA (20 mg kg(-1) ) was administered orally 4 hours preoperatively. Forty-one bio

Temozolomide (TMZ) as a concomitant and adjuvant chemotherapy to radiotherapy following maximal surgical resection is the established standard therapy for patients with newly diagnosed high-grade glioma. However, detailed analysis of chemotherapy-ind

An antiangiogenic approach is especially suitable for the treatment of malignant gliomas. Recently, two large clinical trials in newly diagnosed glioblastoma (the Avastin in Glioblastoma study and Radiation Therapy Oncology Group 0825 study) showed a

We report the unique case of a 69-year-old man with a cerebellar glioblastoma showing an exophytic growth pattern. Magnetic resonance imaging revealed a heterogeneously gadolinium-enhancing tumor in the right cerebellopontine angle. The preoperative

The present retrospective data analysis was performed to determine whether intraoperative pathological diagnosis (IOD) using frozen section (FS) could clearly distinguish high-grade glioma from WHO grade II gliomas. IOD was retrospectively compared t

A new boronated porphyrin compound (STA-BX909) was developed as a possible agent for boron neutron capture therapy. The boron concentration was measured by an in vivo rat experimental brain tumor model and an in vitro cell culture study. This agent w
