Molecular pathology in adult gliomas: diagnostic, prognostic, and predictive markers.Jansen, Michael; Yip, Stephen; Louis, David N; Pathology Service, Massachusetts General Hospital, Boston, MA 02114, USA. (Elsevier, 2010-07)Over the past 10 years, there has been an increasing use of molecular markers in the assessment and management of adult malignant gliomas. Some molecular signatures are used diagnostically to help pathologists classify tumours, whereas others are used to estimate prognosis for patients. Most crucial, however, are those markers that are used to predict response to certain therapies, thereby directing clinicians to a particular treatment while avoiding other potentially deleterious therapies. Recently, large-scale genome-wide surveys have been used to identify new biomarkers that have been rapidly developed as diagnostic and prognostic tools. Given these developments, the pace of discovery of new molecular assays will quicken to facilitate personalised medicine in the setting of malignant glioma.
