Maximal tumor diameter in the preoperative tumor magnetic resonance imaging (MRI) T2 image is associated with prognosis of Grade II Glioma.

摘要: ABSTRACT Factors associated with the prognosis of low-grade glioma remain undefined. In this study, we examined whether maximal tumor diameter in preoperative magnetic resonance imaging (MRI) T2 image is grade II gliomas patients, aiming to provide insights into clinical prediction patient outcome.We retrospectively analyzed data patients Grade glioma, who were hospitalized Xiangya Hospital, Central South University, from 2011 2016. Kaplan-Meier and Cox proportional hazards analyses performed determine association between prognosis.A total 90 included study. Mean age was 37.7 ± 13.0 years, 58.9% them male. survival analysis overall (overall [OS], P = .009) event-free (EFS, P = .002) revealed statistically significant differences lesion <7 cm those ≥7 cm. The MRI identified as a prognostic factor OS (P = .013), while constituting an independent risk for EFS (P = .002) alongside elevated histological after recurrence (P = .006).The independently predicts glioma.
