The genetic features of isocitrate dehydrogenase-wild-type (IDH-wt) lower-grade gliomas (LGGs; World Health Organization grades II and III) are not well defined. This study analyzed the genetic and other features of IDH-wt LGGs to develop a subclassification that can be used to predict their prognosis. Clinical, histopathological, and genetic features of 35 cases of diffuse IDH-wt astrocytoma and IDH-wt anaplastic astrocytoma were analyzed. The following genetic factors were examined: mutations of B-rapidly accelerated fibrosarcoma, telomerase reverse transcriptase promoter (TERTp), histone 3 family 3A, and alpha-thalassemia/mental retardation syndrome, X-linked; and copy number aberrations. In the univariate analysis, the following factors were associated with poor overall survival (OS): the histopathological diagnosis, TERTp mutation, the gain of chromosome 7 (+ 7), and the loss of chromosome 10q (− 10q). In the multivariate analysis, + 7, − 10q, and TERTp mutation were independent prognostic factors associated with poor OS. The median OS was significantly worse for patients who harbored at least one of these factors than for those without any of them (18.5 vs. 54.5 months, P = 0.002). The subclassification of IDH-wt LGGs according to the genetic factors + 7, − 10q, and TERTp mutation is potentially useful for predicting the prognosis.
