Primary and secondary glioblastomas: From concept to clinical diagnosis

Open access
Kleihues, Paul, Ohgaki, Hiroko·1999·Neuro-Oncology

Abstract

Glioblastomas may develop de novo (primary glioblastomas) or through progression from low-grade or anaplastic astrocytomas, (secondary glioblastomas). These subtypes of glioblastoma constitute distinct disease entities that evolve through different genetic pathways, affect patients at different ages, and are likely to differ in prognosis and response to therapy. Primary glioblastomas develop in older patients and typically show EGFR overexpression, PTEN (MMAC1) mutations, CDKN2A (p16) deletions, and less frequently, MDM2 amplification. Secondary glioblastomas develop in younger patients and often contain TP53 mutations as the earliest detectable alteration. These characteristics are derived largely from patients selected on the basis of clinical history and sequential biopsies. Currently available data are insufficient for a substitution of histologic classification and grading of astrocytic tumors by genetic typing alone. More subtypes of glioblastomas may exist with intermediate clinical and genetic profiles, a factor exemplified by the giant-cell glioblastoma that clinically and genetically occupies a hybrid position between primary (de novo) and secondary glioblastomas. Future research should aim at the identification of criteria for a combined clinical, histologic, and genetic classification of astrocytic tumors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
