A national case-control study of Ewing's sarcoma family of tumours in Australia.

Limited population-based epidemiologic information is available on Ewing's sarcoma family of tumours (ESFT), a rare group of neoplasms. Several associations have been noted on a few studies but results were not consistent, except for exposure to farming among cases and their parents. Here we present the non-farm findings of a nationwide case-control study of ESFT in children and young adults in Australia.

Farm exposures, parental occupation, and risk of Ewing's sarcoma in Australia: a national case-control study.

Objective: It has been suggested that parental occupation, particularly farming, increased the risk of Ewing's sarcoma in the offspring. In a national case-control study we examined the relationship between farm and other parental occupational exposures and the risk of cancer in the offspring.

Methods: Cases were 106 persons with confirmed Ewing's sarcoma or peripheral primitive neuroectodermal tumor.

Electronic telephone directory listings: preferred sampling frame for a population-based study of childhood cancer in Australia.

Purpose: We report our telephone-based system for selecting community control series appropriate for a complete Australia-wide series of Ewing's sarcoma cases.

Methods: We used electronic directory random sampling to select age-matched controls. The sampling has all listed telephone numbers on an up-dated CD-Rom.

Population density and childhood leukaemia: results of the EUROCLUS Study.

The EUROCLUS study assembled incidence data for 13,551 cases of childhood leukaemia (CL) diagnosed between 1980 and 1989 in 17 countries (or regions of countries). These were referenced by location at diagnosis to small census areas of which there were 25,723 in the study area. Population counts, surface area and, hence, population density were available for all these small areas.
