Evaluation of low-grade glioma clinical and volume response to concomitant and adjuvant chemo-radiotherapy.

Material and methods:
We describe a series of seven patients (five men and two women) with defined progression or an inoperable residual tumor after low-grade glioma surgery. Tumor volume regression was evaluated by means of manual computer volumetry.

Using computerized volumetric quantification in our pilot set of patients, we observed mean 90% (73–100%) reduction in tumor volume on T1W MRIs and 73% (41–100%) reduction of tumor volume on T2W MRIs. Following cancer treatment, regression of epileptic seizures occurred in three patients, Jacksonian sensory epileptic seizures stayed stable in one patient.

Combined cancer treatment in patients with inoperable low-grade glioma WHO grade II with low proliferation activity could lead to substantial tumor volume regression in a significant proportion of patients.

Key words:
low-grade glioma – chemotherapy – radiotherapy – temozolomide – computer volumetry
