Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All patients will be offered germline genetic testing by a member of their treating oncology team:
- Patients will receive pre-test genetic counselling by member of their treating team, including provision of a general information sheet about the testing
- Participants will then have testing performed by collection of a saliva sample, with testing performed for 16 prostate cancer genes (ATM, BRCA1, BRCA2, CHEK2, EPCAM, HOXB13, MLH1, MSH2, MSH6, NBN, PMS2, TP53, FANCA, PALB2, RAD51D, BRIP1)

Once patients have received their results, they will immediately be provided witha questionnaire evaluating acceptability of the testing process
- a reminder questionnaire will be sent in the mail 4 weeks after the initial questionnaire, if they fail to return a completed questionnaire

Efficacy
Statistical methods / analysis
Descriptive statistics will be used to analyse the survey responses.

A sample size of 44 men will provide 90% power to distinguish a proportion of men who are happy with mainstreaming of 80% vs. 60% or less, with a one-sided alpha of 0.05. Allowing for 25% drop-out, we aim to recruit 60 men. A rate of men happy with testing of over 80% will be considered worthwhile.
