The records of 46 children treated with ifosfamide between 1987-1994 were analyzed. 24 received the drug as first-line chemotherapy in combination with vincristine and etoposide or with adriamycin, vincristine and cyclophosphamide. Complete remission was achieved in 8/10 children with soft tissue sarcoma, 7/8 with Ewing's sarcoma, 2/2 with ovarian carcinoma and 2/2 with clear cell sarcoma of the kidney. 22 children in whom first-line chemotherapy failed were then treated with ifosfamide and etoposide. Complete remission was achieved in 7/10 children with osteosarcoma, 1/2 with Wilms' tumor and 1/3 with neuroblastoma.

In contrast to the occurrence of brain metastases advanced malignant tumours in adult cancer patients, the dissemination of solid tumours to the brains of paediatric cancer patients is very uncommon. We present a neuro-pathological and clinical study of a group of children and adolescents with brain metastases (BM) from extracranial solid malignancies. The analysed patients were diagnosed with soft tissue sarcomas (three), germ cell tumours (three), or osteosarcoma, neuroblastoma, clear cell sarcoma of the kidney, or pleuropulmonary blastoma (one each). In our series, BM frequently coexisted with pulmonary metastases. Three different metastatic patterns were discernible: a solitary tumour, multiple lesions and diffuse parenchymal dissemination. Two cases showed haemorrhagic presentation. Most of the children died due to BM progression, while children with germ cell tumours showed the best prognosis. The histopathological pictures of BM can be different from the primary tumour, showing dedifferentiation or a diverse neoplastic component. The autopsy examination can still be helpful in the final diagnosis of certain cases with atypical clinical presentations.
