Body measurements were taken and the prevalence of major malformations and of 57 minor anomalies was determined in 106 children with malignant disease, in 81 of their sibs, and in 106 control subjects matched to the patients according to sex, age and ethnic origin. Leukaemic children had a significantly smaller head circumference than the corresponding control children, but no significant differences in height, anthropometric and syndromologic indices were found. No differences were observed in the frequency of associated major malformations including renal malformations detectable by sonography. The prevalence of minor anomalies was significantly higher in the patients with malignant disease and their sibs than in the control children: 69.2% of the patients, 63.0% of the sibs and 34.6% of the control subjects had at least one minor anomaly. When two and more minor anomalies were considered, the prevalence figures were 36.5%, 29.6% and 12.5%, respectively. Among the single minor anomalies only the Sydney line was significantly more frequent in patients with solid tumours. No specific association of an individual dysplasia or a pattern of minor anomalies with a given tumour could be established.
