89 Background: Preservation of EF is a goal of care for many men with newly diagnosed prostate cancer. In order to accurately counsel patients regarding their likely treatment outcome, an assessment of baseline EF, and screening for known risk factors, should form part of the assessment of all prostate cancer patients. Methods: We performed a retrospective review of prospectively-collected data regarding baseline EF in men with prostate cancer referred for a radiotherapy opinion. 1173 consecutive patients referred over a 5.5 year period from 2011-16 were included. All patients were offered the opportunity to complete the International Index of Erectile Function (IIEF-5) questionnaire in privacy. Information on known risk factors such as age, vascular comorbidity, smoking and alcohol history, and cardiovascular risk factors was recorded. Results: Of the 1173 patients, 233 were excluded due to metastatic disease at referral. Of the remaining 940 with localised disease, 812 (86%) completed the questionnaire. 561 (69%) successfully filled the questionnaire yielding a score. A further 251 (31%) commented on the questionnaire without completing the score (see table). Median age was 66years (IQR 62-71). 574(61%) had known risk factors for erectile dysfunction such as hypertension or diabetes. 173 (18.5%) had a history of peripheral, cardiovascular, or cerebrovascular disease. Smoking and alcohol history was available for 645 patients, 353(60%) had a smoking history, and 450(70%) had a history of alcohol use. Conclusions: In this population, there is a high prevalence of baseline erectile dysfunction (IIEF-5 ≤16), 242/561 (43%). Additionally, significant numbers of patients were sexually inactive or unconcerned regarding ED. Known risk factors for erectile dysfunction were common in this population, many of which are modifiable. [Table: see text]
