OBJECTIVE This single-arm, open-label, Phase II study evaluated the efficacy and safety of single-agent bevacizumab, a monoclonal antibody against vascular endothelial growth factor, in Japanese patients with recurrent malignant glioma. METHODS Patients with histologically confirmed, measurable glioblastoma or World Health Organization Grade III glioma,(More)
OBJECT Malignant gliomas remain incurable despite modem multimodality treatments. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), also known as Apo2L, a member of the TNF family, preferentially induces apoptosis in human tumor cells through its cognate death receptors DR4 or DR5, suggesting that it may serve as a potential therapeutic(More)
OBJECTIVE To study the expression and function of L-type amino acid transporter 1 (LAT1), a major catalytic subunit of system L that is responsible for the transport of large neutral amino acids, including most essential amino acids, in concert with the covalently bound 4F2 heavy chain, and is implicated in tumorigenesis. METHODS Human glioma cell lines(More)
A 38-year-old man gradually developed gait instability, dysarthria, and dysphagia over two months associated with an elevated blood pressure after starting hemodialysis therapy for diabetic nephropathy. Brain MRI studies indicated vasogenic edema in the brainstem, extending from the lower midbrain to the upper medulla oblongata. The patient's high blood(More)
BACKGROUND Temozolomide (TMZ) is active against newly diagnosed glioblastoma (GBM), and O(6)-methylguanine-DNA methyltransferase (MGMT) is implicated in resistance to TMZ and nitrosoureas. We evaluated the efficacy and safety of the standard 5-day TMZ regimen in patients with recurrent GBM after initial therapy including nitrosourea-based chemotherapy, in(More)
OBJECTIVE AND IMPORTANCE The authors report a rare case of meningeal melanocytoma presenting with unconsciousness, which was caused by an intracerebral hematoma and associated with a history of ipsilateral nevus of Ota. CLINICAL PRESENTATION A 75-year-old woman developed nevus of Ota in the first and second divisions of the right trigeminal nerve(More)
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/Apo2 L) preferentially induces apoptosis in human tumor cells through its cognate death receptors DR4 or DR5, thereby being investigated as a potential agent for cancer therapy. Here, we applied fully human anti-human TRAIL receptor monoclonal antibodies (mAbs) to specifically target one of(More)
Human chorionic gonadotropin (hCG) production has been utilized as a diagnostic marker for germinoma with syncytiotrophoblastic giant cells (STGC) and choriocarcinoma. Elevated hCG in germinoma is considered to predict less favorable prognosis, and an intensive treatment strategy may accordingly be applied. However, there is some evidence that any germinoma(More)
We report a case of a 51-year-old woman with newly diagnosed glioblastoma multiforme (GBM) who was treated with surgery followed by the standard concomitant temozolomide (TMZ) and radiotherapy (RT). Although TMZ is generally safe and well-tolerated, she developed a sudden onset of prolonged and severe thrombocytopenia as the most prominent event of(More)
Primary central nervous system lymphoma (PCNSL) is a rare malignancy confined to the central nervous system (CNS), and majority of PCNSL is pathologically classified as diffuse large B-cell lymphoma (DLBCL). We have now performed whole-exome sequencing for 41 tumor tissues of DLBCL-type PCNSL and paired normal specimens and also RNA-sequencing for 30(More)
