Abstract
Knowledge about interest in genetic testing and willingness-to-pay for a genetic test among men afected from prostate
cancer (PCa) is limited. This study aimed to gain insight into men’s attitudes in genetic testing for PCa. 4699 men with PCa
from the German multicenter prospective database “Familial Prostate Cancer” were included. Interest in, Willingness-to-
pay for and Willingness-to-recommend a genetic test for PCa were quantifed. Associations with several sociodemographic
and psychosocial variables were evaluated by logistic regression. 76.8% of the afected men with a median follow-up of
12.9 years were interested in a genetic test for PCa. Newly identifed variables signifcantly associated with interest were
having sons (OR 1.66, p < 0.001) and a high perceived severity of the PCa (OR 1.40, p < 0.001). 19% of men were willing to
pay more than 500 € for a genetic test. Men with higher education, men with a better self-reported economic situation and
men with a lethal PCa in their family were more likely to be willing to pay a larger sum for a test. 84.9% of men were willing
to recommend a test to their relatives. Interest in genetic testing for PCa among afected men was generally high with most
men willing to recommend a test to their relatives. Various characteristics associated with interest and willingness-to-pay
larger sums for genetic testing were uncovered and need to be addressed when designing both future educational material
and genetic tests for PCa.

Background
Prostate cancer (PCa) remains the most common non-cuta-
neous cancer among men in Germany and in the United
States. Lifetime risk for developing PCa in men is 12.8% in
Germany and 12.9% in the United States [1–3].
Established risk factors for developing PCa are higher
age [4], African American ethnicity [5] and positive family
history of PCa [6]. Men with a frst-degree relative diag-
nosed with PCa have a two to threefold increased risk for
the disease and men from hereditary prostate cancer (HPC)
families show an increase of risk up to sevenfold [7, 8]. The
widely used defnition of an HPC family by Carter defnes it
as (1) at least three afected frst-degree relatives with PCa or
(2) an afected man in each of three successive generations
or (3) two afected frst-degree relatives diagnosed with PCa
younger than 55 years [9].
Although shared environment cannot be excluded as an
explanation for familial aggregation, genetic susceptibility
