Abstract:
PURPOSE: The incidence of multiple primary malignant neoplasms increases with age. An unforeseen finding is the high number of prostate and bladder cancers pairs. Of prostate and bladder cancers pair as first primary and second primary cancers and vice versa, we investigated the differences in clinicopathological features between synchronous and metachronous primary carcinomas of the bladder and prostate. MATERIALS AND METHODS: Fifty-three patients diagnosed with dual prostate and bladder cancer in a 12-year period (2004–2015) excluding cases with incidental prostate cancer after radical cystectomy were reviewed. Enrolled patients were divided into 3 groups according to cancer development (group I, synchronous cancer; group II, prostate cancer with metachronous bladder cancer; group III, bladder cancer with metachronous prostate cancer). Each group was compared according to clinicopathological features. RESULTS: Median age was 72 years (range, 54–83 years). Groups I, II, and III comprised 29 (54.7%), 8 (15.1%), and 16 patients (30.2%), respectively. Age, prostate-specific antigen, tumor stage, grade, multifocality of bladder tumor, and treatment modality did not show statistical differences between groups. However, group III showed a lower prostate cancer stage (National Comprehensive Cancer Network anatomic stage; p=0.009) and had low-risk of prostate cancers (p=0.025). CONCLUSIONS: Bladder tumor showed no differences in the clinicopathological features between synchronous and metachronous primary carcinomas. However, metachronous prostate cancer showed better clinicopathological features of prostate cancer. It is important for clinicians to counselling and decision making in clinical situations
