title: Long term remission of intrinsic brainstem gliomas: the case reports of two children.
abstract: Intrinsic brainstem gliomas carry the worst prognosis of all pediatric CNS tumors; only 10-25% of patients are expected to survive for more than two years. Over a period of four years seven intrinsic brainstem gliomas were diagnosed in children in one institution. Four of them underwent a rapidly fatal course, whilst one was diagnosed only two years ago, which is too recent for long-term evaluation. We report the case histories of the remaining two boys, who showed a favorable course of their disease. Presenting symptoms were headaches and signs of brainstem dysfunction with multiple bilateral cranial nerve palsies, ataxia and pyramidal tract signs. Diagnosis rested on neuroimaging (CAT scans and/or MRI scans). Both tumors were intrinsic brainstem gliomas, one diffuse and the other focal. They responded to treatment (radiotherapy and chemotherapy in the former patient and radiotherapy alone in the latter patient). The two boys became long-term survivors and have remained well, without evidence of disease, for more than 71 and 61 months, respectively, after completion of treatment. They are probably cured. Prompt therapy with curative intention is recommended, with consistent adherence to the chosen antitumor regimen even in poor-risk brainstem gliomas.
