Y Chromosome May Have Role in Prostate Cancer

NEW YORK JAN 02, 2007 (Reuters Health) - The Y chromosome may be

involved in prostate cancer, suggest findings of an Israeli study in

which fathers with only daughters had a higher risk of prostate cancer

than did fathers with at least one son.

" Overall, our findings are consistent with hypotheses that tie Y

chromosome loci to prostate cancer, although other explanations cannot

be excluded, " write Dr. Harlap of Columbia University, New York,

and colleagues in the January 3rd issue of the Journal of the National

Cancer Institute.

Among 38,934 fathers in a family-based research cohort who were followed

for up to 40 years after the birth of their children, 712 developed

prostate cancer.

Compared with men who had at least one son, men with only daughters had

an adjusted relative risk of prostate cancer of 1.40 (p < 0.0001).
