Is the prostate cancer screening behaviour of men with familial predisposition predictable?

Little is known about the motives of German men to attend or refuse preventive checkups for prostate cancer. The aims of this study were to investigate if in men with familial predisposition screening behaviours are influenced by epidemiological or clinical parameters of prostate cancer of their affected relatives. 476 probands with one and 312 probands with at least two affected relatives were advised in writing to have a PSA-test and DRE done at their local urologists. We evaluated if the response rate was correlated to the proband's age, to the number and the age of onset of their affected relatives and also to the clinical course of their disease. Our data implicate that in men with familial predisposition the acceptance of prostate cancer screening is influenced only by individual characteristics and personal attitude and not by factors within the family. To which extent the awareness of disease risk is modified by familial predisposition remains to be evaluated.
