[A case-control study of testicular cancer].

ABSTRACT

PIP: A study on the possible association of maternal factors with testicular cancer was undertaken. Comparisons were made among 2 group of women: those mothers of testicular cancer cases (n=37) and those mothers of men without the disease (n=37). Cases were collected from the records of 9 hospitals, and controls were selected from 5 public health centers by individually matching the sex and year of birth with the testicular cancer cases. Mothers of the cases had significantly fewer livebirths than those mothers of the control group (the adjusted odds ratio per livebirths=0.4, p=0.02) when the 5 following variables were simultaneously adjusted by the logistic regression analysis: Quetelet's Index of mothers before pregnancy, age at index birth, duration of breastfeeding for an index child, birth order of an index child, and number of induced abortions. The endogenous hormonal milieu of a mother may also be associated with the occurrence of testicular cancer in her child. (author's modified)
