TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To determine the effect of a large prostate at radical retropubic prostatectomy (RRP) on the pathological outcome, biochemical recurrence rates, potency and continence.', 'From a database of 440 patients treated with RRP, retrospective information was obtained on prostate weights, patient and tumour characteristics, and follow-up. Potency and continence after RRP was obtained using a self-reported validated questionnaire. Patients with prostates of > 75 or < or = 75 g were compared.', "The median (range) prostate size was 87 (76-182) and 42 (4.1-75) g in the two groups. The response rate to the questionnaire was 78% (344 men). Patients with prostates of > 75 g were older, with a median (range) age of 65 (51-74) years, than the other group, at 61 (40-76) years (P = 0.01), and had higher initial prostate-specific antigen (PSA) levels, at 9.6 (3.4-37.8) and 7.6 (0.1-30.0) ng/mL, respectively (P = 0.001). Tumours within larger prostates were of a lower stage (P = 0.035), lower Gleason grade (median 6 and 7, P = 0.015), of smaller volume (median 1.0, 0.1-12.4; and 1.5, 0.1-21.1 mL; P = 0.04) and more often 'clinically insignificant' (23% and 6%, P = 0.001). There was no difference in the number or distribution of positive surgical margins. For a limited median follow-up of 20-25 months, patients with prostates of > 75 g were less likely to have biochemical recurrence (5% vs 24%, P < 0.001). Potency and continence rates were similar between the groups."] Does a large prostate at radical retropubic prostatectomy adversely affect cancer control , continence or potency rates?
