摘要:

collected for 42 patients with cerebellar medulloblastoma diagnosed and treated in Western Australia between the years 1961 and 1984. Thirty‐one patients were male and 12 were over 14 years of age. In 31 patients the neoplasms were localized to the midline, while in 10 they were placed laterally in the cerebellar hemispheres. The remaining patient had a diffusely spreading neoplasm in the meninges of the posterior fossa. Thirty‐nine underwent surgical treatment followed by postoperative radiotherapy. Three patients died in the early postoperative period. Twenty‐four patients survived for one year or longer, 15 for two or more years, 10 for five years, and five survived longer than 10 years. The survival proportions estimated by the life‐table method were 66% at one year, 48% at two years and 32% at 5 and 10 years. In one patient who survived for 23 years a meningioma developed, possibly due to radiotherapy.

摘要:

Information which relates morbidity or mortality to environmental conditions (exposure‐response relationships) forms the basis for public health as well as for clinical action. For both types of action, the information base is the same, neither complete nor comprehensive. So, both types of action are based on hypothesis, the best available to explain the facts, but subject to review in the light of new facts. Even though the volume of information may be considerable, as in the case of asbestos, there are always gaps in knowledge to be bridged by judgement. This should be made on the basis of as complete an evaluation as possible of all the available evidence.
