Prostate cancer incidence on cystoprostatectomy specimens is directly linked to age: results from a multicentre study. | LitMetric

AI Article Synopsis

Article Abstract

Objective: To assess the incidence and age-related histopathological characteristics of incidentally diagnosed prostate cancer from specimens obtained via radical cystoprostatectomy (RCP) for muscle-invasive bladder cancer.

Patients And Methods: A retrospective review of the histopathological features of 2424 male patients who underwent a RCP for bladder cancer was done at eight centres between January 1996 and June 2012. No patient had preoperative suspicion of prostate cancer. Statistical analyses were performed in different age-related groups.

Results: Overall, prostate cancer was diagnosed in 518 men (21.4%). Incidences varied significantly according to age (5.2% in those aged <50 years to 30.5% in those aged >75 years, P < 0.001). Most of the prostate cancers were considered as 'non-aggressive', that is to say organ-confined (≤pT2) and well-differentiated (Gleason score <7). Tumour-Node-Metastasis (TNM) stage and proportion with a Gleason score of ≥7 were significantly greater in older patients (P < 0.001). Apart from age, there were no preoperative predictive factors for 'non-aggressive' prostate-cancer status. At the end of the follow-up, only nine patients (1.7%) had biochemical recurrence of prostate cancer, and no preoperative predictive factors were identified.

Conclusion: The rate of incidentally diagnosed prostate cancer from RCP specimens is ≈20%, most of them being organ-confined and well-differentiated. The probability of having a 'non-aggressive' prostate cancer decreases in older men.
