Open AccessImpact of tumor markers on diagnosis, treatment and prognosis in CNS germ cell tumors: correlations with clinical practice and histopathology
Tumor markers in CNS germ cell tumors (GCTs) include human chorionic gonadotropin (HCG) and alpha fetoprotein (AFP), which have significant diagnostic implications, as elevation of either one leads to clinical...

Histopathology and prognosis of germ cell tumors metastatic to brain: cohort study
Germ cell tumors (GCTs) are uncommon neoplasms predominantly arising in midline tissues. The prognostic significance of histopathology in predicting metastatic GCT behavior is poorly understood.

Prospective trial evaluating the sensitivity and specificity of 3,4-dihydroxy-6-[18F]-fluoro-l-phenylalanine (18F-DOPA) PET and MRI in patients with recurrent gliomas
Treatment-related changes can be difficult to differentiate from progressive glioma using MRI with contrast (CE). The purpose of this study is to compare the sensitivity and specificity of 18F-DOPA-PET and MRI...

Phase II trial of pre-irradiation and concurrent temozolomide in patients with newly diagnosed anaplastic oligodendrogliomas and mixed anaplastic oligoastrocytomas: long term results of RTOG BR0131
We report on the long-term results of a phase II study of pre-irradiation temozolomide followed by concurrent temozolomide and radiotherapy (RT) in patients with newly diagnosed anaplastic oligodendroglioma (A...

The impact of concurrent temozolomide with adjuvant radiation and IDH mutation status among patients with anaplastic astrocytoma
This study assesses the controversial role of temozolomide (TMZ) concurrent with adjuvant radiation (RT) in patients with anaplastic astrocytoma (AA). The impact of isocitrate dehydrogenase (IDH) status on the...

Interlaboratory comparison of IDH mutation detection
Isocitrate dehydrogenase (IDH) mutational testing is becoming increasingly important. For this, robust and reliable assays are needed. We tested the variation of results between six laboratories of testing for...

The role of LAT1 in 18F-DOPA uptake in malignant gliomas
Positron emission tomography (PET) imaging with the amino acid tracer 6-18F-fluoro-l-3,4-dihydroxy-phenylalanine (18F-DOPA) may provide better spatial and functional information in human gliomas than CT or MRI al...

Expression of CD74 in high grade gliomas: a potential role in temozolomide resistance
Temozolomide (TMZ) is the most effective chemotherapeutic agent for glioblastoma (GBM). Resistance to this methylating agent is linked to DNA repair enzyme O6-methylguanine-DNA methyltransferase (MGMT). Howeve...

Phase II NCCTG trial of RT + irinotecan and adjuvant BCNU plus irinotecan for newly diagnosed GBM
Irinotecan has radiosensitizing effects and shows synergism with nitrosoureas. We performed a Phase II study of RT and irinotecan, followed by BCNU plus irinotecan in newly-diagnosed GBM. The MTD for patients ...

Evaluation of MGMT promoter methylation status and correlation with temozolomide response in orthotopic glioblastoma xenograft model
CpG methylation within the O6-methylguanine-DNA-methyltransferase (MGMT) promoter is associated with enhanced survival of glioblastoma multiforme (GBM) patients treated with temozolomide (TMZ). Although MGMT prom...

Prognosis in patients with anaplastic oligoastrocytoma is associated with histologic grade
Anaplastic oligoastrocytomas (AOA) are relatively uncommon high-grade gliomas. While oligodendroglial elements are thought to be associated with better outcomes, the magnitude of the difference is not clear.
