There have been significant advancements in diagnostic radiology and pathology, and in the technical aspects of surgery, radiation therapy, and temozolomide (TMZ) used for treatment of this disease.

Serial multiparametric magnetic resonance imaging–based follow-up ensured early detection of disease progression. Appropriate salvage therapy was determined based on clinicopathological attributes.
