Glioma biology and molecular markers.
Salt Lake City, United States. In Cancer Treat Res, 31 Dec 2014
Prognostic markers in diffuse gliomas include IDH mutation, 1p/19q codeletion, and MGMT methylation, and MGMT is also a predictive marker in elderly patients with glioblastoma treated with temozolomide monotherapy.
Molecular biology of high-grade gliomas: what should the clinician know?
Zürich, Switzerland. In Ai Zheng, Jan 2014
Recent practice-changing clinical trials have defined a role for routine assessment of O-6-methylguanine-DNA methyltransferase (MGMT) promoter methylation in glioblastoma patients, especially in the elderly, and 1p and 19q codeletions in patients with anaplastic glial tumors.
Case comparison and literature review of glioblastoma: A tale of two tumors.
Portland, United States. In Surg Neurol Int, Dec 2013
The following markers were assessed: O (6)-methylguanine DNA methyltransferase (MGMT) methylation, isocitrate dehydrogenase (IDH) 1 and 2 status, epidermal growth factor receptor (EGFR) amplification, phosphatase and tensin homolog (PTEN) status, Ki-67, p53, and 1p/19q status.
The somatic genomic landscape of glioblastoma.
New York City, United States. In Cell, Nov 2013
Correlative analyses confirm that the survival advantage of the proneural subtype is conferred by the G-CIMP phenotype, and MGMT DNA methylation may be a predictive biomarker for treatment response only in classical subtype GBM.
Intrinsic molecular subtypes of glioma are prognostic and predict benefit from adjuvant procarbazine, lomustine, and vincristine chemotherapy in combination with other prognostic factors in anaplastic oligodendroglial brain tumors: a report from EORTC study 26951.
Rotterdam, Netherlands. In J Clin Oncol, Feb 2013
They are prognostic for PFS independent of clinical (age, performance status, and tumor location), molecular (1p/19q loss of heterozygosity [LOH], IDH1 mutation, and MGMT methylation), and histologic parameters.
