Low-grade gliomas in children: tumor volume response to radiation.

摘要: Object. The authors conducted a retrospective review to examine and document the frequency, degree, timing of radiologically confirmed response radiotherapy low-grade gliomas in children. Methods. Between 1963 1995, 80 patients 17 years age or younger were referred London Regional Cancer Centre London, Ontario after diagnosis glioma. All underwent surgical resection biopsy procedures 47 (40 postoperatively seven at time tumor progression). Nineteen with residual measurable lesions who received radiation therapy selected for volumetric analysis this treatment. extent determined by process comparing postoperative, preirradiation computerized tomography (CT) scans postirradiation, follow-up CT scans. For one patient comparison was made using serial magnetic resonance images. Residual found on postoperative ...
