[Evaluation of treatment results in glioma using computed tomography]

A total of 1,020 CT-studies were conducted in 234 patients with glial tumors of the brain before treatment and in different periods after operation, radiotherapy, and polychemotherapy. The CT findings were compared with the clinical and morpological findings. The author formulated the CT-syndrome of glioma regression after treatment, which corresponded to the stage of clinical remission, and the CT-signs of glioma growth activation, which corresponded to the initial stage of a clinical recurrence. The CT-symptoms of continued glioma growth appear 4-6 months ahead of a clinical recurrence in patients with gliomas of I-II degree of malignancy and 2-3 months ahead in those with III-IV degree malignancy.
