This study aimed to determine whether cancer risk was elevated among patients exposed to radiation from diagnostic cardiac catheterization during childhood.
The study cohort included 3915 children who underwent at least one cardiac catheterization at a major children's hospital in Toronto, Canada, between 1950 and 1965, were <=18 years at the time of the procedure, and were residents of Ontario.
Follow-up of the cohort was done by linkage to the Ontario Cancer Registry up to 1986.
A total of seven cancer deaths were observed (0), compared with 5.7 expected (E) based on provincial cancer rates (mortality ratio [O/E]=1.2; 90% confidence interval [CI]:0.6-2.3).
In the analysis of cancer incidence, 13 cancers were detected, compared with 17.3 expected (O/E= 0.75; 90% CI:0.4-1.2).
