Summary
Background: Low-grade gliomas WHO II (LGG) are mostly detected in patients with neurological symptomatology between 20 and 45 years of age very often as secondary epilepsy. We present two cases in which low-grade gliomas attacked neurological zones. Neurosurgical resection was subtotal because of the risk of the damage in neurocognitive functions in both these patients. After the operation, both patients were followed at neurosurgery department in regular intervals using different imaging methods (MRI, MRS and PET). After resections, the MRI detected the enlargement of the volumes of the tumor residua in both patients. Patients and methods: Owing to the risk of up-grading to high-grades glial tumors (overexpression of EGFR and VEGF), both patients were indicated for curative treatment by external beam radiotherapy combined with chemotherapy (Temodal®) and adjuvant chemotherapy. Results: After the end of this treatment, the MRI proved considerable partial regressions in both patients. Moreover, three months later, the MRI did not prove any residual disease. Conclusion: Radiotherapy combined with the administration of Temodal should prolong the OS and TTP in patients with a high risk of up-grading of low-grade gliomas of the brain. Both the patients are in a follow-up program, also because of the risk of duplicite brain tumor.
