title: [Evaluation of the results of surgery of intracranial supratentorial tumors in 363 children over the past 50 years (1948-1997)].
abstract: At the Department of Neurosurgery, Hradec Králové, in the course of 50 years (1948-1997) 363 children, 199 boys and 164 girls (1.2:1) aged under 18 years were operated on for intracranial supratentorial tumours. The average age in children at the time of first operation was 9.3 years; most frequently they participated those of 8 and 11 to 14 years of age. Children aged 1, 2 and 3 years constituted 4.7%, 4.4% and 5% of operations. The tumours were located in: cerebral hemispheres 123 (33.8%), lateral ventricles 17 (4.7%), IIIrd ventricle 5 (1.4%), hypothalamus 26 (7.2%), thalamus 19 (5.2%), basal ganglia 24 (6.6%), sellar region 86 (23.7%), chiasmatic region 38 (10.5%) and pineal region 19 (5.2%). 223 of tumours (61.4%) were located in the midline and 140 of them (38.6%) laterally (in hemispheres and lateral ventricles of the brain). 268 of tumours were histologically verified (73.8%) and 95 of cases were evaluated according to the neurosurgeon's point of view and/or to the clinical and CT controls (26.2%), because of the biopsy (especially in the pre-CT era) was highly riskfull. Histological typing of tumours was retrospectively reevaluated according to the present WHO classification. Summarized 53 types of tumours were differentiated. The most frequent lesions were various variants of astrocytic gliomas (135 = 37.2%). Further on the craniopharyngiomas dominated (73 = 20.1%). The tumours were operated on through craniotomies 299 times, by primarily drainage operations 52 times, functions 6 times, stereotactically 8 times and or by combination of these operations 82 times. Reoperation was needed for postoperative complications in 1.7% (6 times) and for delayed recurrence in 11.3% (41 times). The postoperative mortality (up to 1 month after initial surgery) was in 156 children operated on in pre-CT era (between 1948 and 1977), as compared with 207 children operated on in the era of CT (between 1978 and 1997) in astrocytomas 3.8:0%, pilocytic astrocytomas 6.5:2.8%, craniopharyngiomas 15.4:0% and in all tumours 12.2:2.9%. 16 children with orbital tumours (the average age 5.8 years) operated on with orbitofrontal approach were also evaluated. 14 of them survive for 5-37 years (on the average 16.6 years). The chronological development of diagnostic and operative processes of supratentorial tumours in children's care is discussed. The prognostic elements of present histobiological classification of tumours are positively evaluated.
