Hypothesis

Do older parents have a higher risk of having children with Wilms' tumour?

Conclusion

The study found that older parental age is associated with an increased incidence of sporadic Wilms' tumour.

Supporting Evidence

  • An increasing incidence of sporadic Wilms' tumour was found with increasing paternal age.
  • A relative risk of 2.1 was observed for children of fathers over 55 compared to those under 20.
  • A similar effect for maternal age showed a relative risk of 1.4 for mothers over 40.

Takeaway

If your parents are older when you are born, you might have a higher chance of getting a type of kidney cancer called Wilms' tumour.

Methodology

The study compared parental age distributions of Wilms' tumour patients to the general population and analyzed subgroups based on various factors.

Potential Biases

Limitations

The study may be biased due to incomplete ascertainment of cases and geographical differences in parental age distributions.

Participant Demographics

Patients were white, born in the US, and had no confirmed family history of Wilms' tumour.
