1) Histologically proven Grade II astrocytoma by WHO2016 classification. A large single tumor extending 3 lobes is included when it is histologically diagnosed as grade II astrocytoma.
For those who had additional surgery, he/she must meet a) or b).
a) diagnosed with Grade II astrocytoma after both primary and addtional surgeries by WHO2016 classification.
b) undiagnosed after ptimary surgery and diagnosed with Grade II astrocytoma after additional surgery by WHO2016 classification.
2) No history of previous therapy for tumor except resection or biopsy.
3) No clinically systemic metastasis (Imaging study except chest X-ray is not mandatory).
4) 50% or more of the tumor existing in the cerebrum and diencephalon on preoperative MRI.
5) Postoperative MRI within 42 days after surgery revealed residual tumor and the extension of removal of the tumor by volumetric method shows either (A) or (B).
(A) Tumor resection < 90%
(B) Tumor resection >=90% and <100%, and classified as high risk by EORTC low grade glioma score

(1) age >= 40 years
(2) largest diameter of the tumor >= 60 mm
(3) tumor crossing the midline
(4) astrocytoma histology subtype
(5) presence of neurologic deficit
6) Preoperative MRI revealed no multiple legions or dissemination.
7) Preoperative and postoperative MRI revealed measurable or non-measurable disease.
