Radical resection of chiasmatic-hypothalamic glioma (CHG) carries a significant risk of morbidity and the optimum treatment remains undecided. The authors reported 9 children with CHG, who were treated with surgical resection with or without postoperative chemotherapy. Age at the time of diagnosis ranged from 4 months to 7.7 years (mean 3.1 years), and no patient had evidence of neurofibromatosis type 1. Surgical resections of the tumors were performed in all patients because of severe visual impairment or intracranial hypertension caused by large tumors. All of the surgical interventions resulted in partial resections. Pathological examination revealed pilocytic astrocytomas in 7 patients, low grade astrocytoma in 1 and anaplastic astrocytoma in 1. Seven patients with residual tumors received postoperative chemotherapy consisting of cisplatin, cyclophosphamide, etoposide and vincristine. Reduction in tumor size was noticed in 5 patients, although 2 patients had no response and switched to local radiotherapy. Although minor complications of chemotherapy were noticed in 5 patients, severe sequelae such as neuropsychological deficits or endocrinopathies did not occur, and all patients completed chemotherapy programs. Additional treatments are recommended in case of incomplete tumor resections, because our experience demonstrates that the majority of the residual tumors have potential to progress. Our present data suggests that the chemotherapy of the aforementioned regimen is effective in controlling CHGs after partial resections and is relatively well tolerated even in young children who are vulnerable to radiotherapy.
