Prostate cancer incidence and disease-specific survival in men participating in the ERSPC with an initial PSA less than 3.0 ng/mL

7 Background: The European Randomized Study of Screening for Prostate Cancer (ERSPC) applies a prostate- specific antigen (PSA) cut-off >3.0 ng/mL as an indication for biopsy. We analyzed the incidence and disease-specific mortality for prostate cancer (PC) within ERSPC Rotterdam for men with an initial PSA Methods: From 1993-1999, a total of 42,376 men identified from population registries in the Rotterdam region (55-74 yrs) were randomized to a screening or control arm. During the first screening round 19,950 men were screened, with biopsies being initially recommended in case of abnormal DRE or PSA >4.0 ng/mL. From 1997 on, solely PSA >3.0 ng/mL was used. The screening interval was 4 yrs. A total of 15,758 men (79%) had an initial PSA Results: From 1993-2008, 915 PC cases were diagnosed in 15,758 men (5.8%, median age 62.3 yrs) with an initial PSA T2c, Gleason score >8, PSA >20 ng/mL, positive lymph nodes or metastases at diagnosis) was detected in 65/733 screen detected PC (8.9%) and 102/182 interval detected PC (56.0%). PC death occurred in 23 cases (5 screen detected and 18 interval detected) in the total population (0.15%), with increasing risk in men with higher initial PSA values. Conclusions: The risk of (aggressive) PC and PC mortality in a screening population with initial PSA [Table: see text] [Table: see text]
