ObjectivesTo assess the association between physical activity, evaluated by the Physical Activity Scale for the Elderly (PASE) questionnaire, and prostate cancer risk in a consecutive series of men undergoing prostate biopsy. Patients and MethodFrom 2011 onwards, consecutive men undergoing 12-core prostate biopsy were enrolled into a prospective database. Indications for a prostatic biopsy were a prostate-specific antigen (PSA) value of ≥4 ng/mL and/or a positive digital rectal examination. Body mass index (BMI) and waist circumferences were measured before the biopsy. Fasting blood samples were collected before biopsy and tested for: total PSA, glucose, high-density lipoprotein cholesterol, and trygliceride levels. Blood pressure was recorded. Metabolic syndrome (MetS) was defined according to the Adult Treatment panel III. The PASE questionnaire was completed before the biopsy. ResultsIn all, 286 patients were enrolled with a median (interquartile range, IQR) age and PSA level of 68 (62-74) ConclusionIn our single-centre study, increased physical activity, evaluated by the PASE questionnaire, is associated with a reduced risk of prostate cancer and of high-grade prostate cancer at biopsy. Further studies should clarify the molecular pathways behind this association.

Contrast-enhanced transrectal colour power-Doppler sonography increases specificity in the detection of local recurrence after prostatectomy. Magnetic resonance imaging yields equivalent accuracy. Biopsy remains the diagnostic gold standard, but the use of imaging methods may reduce the number of biopsies.

In our study, a moderate/high CVR is associated with an increased risk of a high-grade Gleason score when PCa is diagnosed on biopsy. Although these results should be confirmed in multicentre studies, patients with moderate/high CVR should be carefully evaluated for PCa diagnosis.
