To determine prognostic factors and optimal timing of postoperative radiation therapy (RT) in adult low-grade gliomas. ⋯ This study supports the association between aggressive surgical resection and better OS and PFS, and between postoperative RT and improved PFS in patients receiving STR/biopsy only. In addition, our findings suggest that delaying RT until progression is safe in patients who are eligible.
