183 Background: Prostate cancer has long been considered as a disease of older men. However, age at diagnosis with prostate cancer has continued to decline. Since the introduction of prostate-specific antigen (PSA) test in 1986, the prostate cancer incidence rate has steadily and dramatically increased in men under age 50. This study aims to better understand demographic variations in prostate cancer screening and incidence, and clinical characteristics of prostate cancers in men under age 50. Methods: We examined prostate cancer testing data from the Behavioral Risk Factor Surveillance System (2002, 2004, 2006, and 2008) and prostate cancer incidence data from the CDC's National Program of Cancer Registries and the NCI's Surveillance, Epidemiology, and End Results programs (2001-2006). We estimated the weighted percentage of self-reported cancer testing using SUDAAN and age-adjusted cancer incidence rates and trends using SEER-STAT. Statistical significance for trends was determined by the annual percentage change (APC) differing form zero. Results: A total of 29,176 prostate cancer cases were identified from 2001-2006 among men under age 50. Of these, 551 (1.9%) were among men under age 40. Incidence rates remained stable from 2001-2006; however the incidence of well-differentiated tumors decreased significantly (APC=−24.7) during this time period. About 44% of men aged 40-49 years old reported having a prostate cancer test in the past two years. Prostate cancer testing and incidence rates were highest among men who were black, non-Hispanic, or lived in the northeast. Black men had more than a 2-fold increase in cancer incidence than white men. Conclusions: The magnitude of prostate cancer testing and incidence in men under age 50 reveals significant health/public health problems in this younger population. This study demonstrates substantial regional differences in prostate cancer testing and incidence in men under age 50. It also confirms that prostate cancer testing and incidence varies by race and ethnicity. We observed a large disparity in prostate cancer incidence between blacks and whites. The incidence rate remained stable over time; the dramatic decrease occurred in well-differentiated cancers. No significant financial relationships to disclose.

Psa Testing

Abstract Background The 2012 US Preventive Services Task Force recommendation against routine prostate-specific antigen (PSA) testing led to a decrease in prostate cancer screening, but the heterogeneity of its impact by race and ethnicity remains unclear. Methods The proportion of 40- to 74-year-old men who self-reported receiving a routine PSA test in the past year was estimated in the Behavioral Risk Factor Surveillance System (2012-2018). Odds ratios (ORs) of undergoing screening by race and ethnicity were estimated, adjusting for healthcare–related factors. Prostate cancer incidence rates and rate ratios (IRRs) by race and ethnicity were estimated using Surveillance, Epidemiology, and End Results registry data (2004-2017). Results PSA testing frequencies were 32.3% (95% confidence interval [CI] = 31.7% to 32.8%) among non-Hispanic White (NHW), 30.3% (95% CI = 28.3% to 32.3%) among non-Hispanic Black (NHB), 21.8% (95% CI = 19.9% to 23.7%) among Hispanic, and 17.7% (95% CI = 14.1% to 21.3%) among Asian and Pacific Islander men in 2012. The absolute screening frequency declined by 9.5% from 2012 to 2018, with a larger decline among NHB (11.6%) than NHW men (9.3%). The relative annual decrease was greater among NHB (OR = 0.86, 95% CI = 0.84 to 0.88) than NHW men (OR = 0.89, 95% CI = 0.89 to 0.90; Pheterogeneity = .005), driven by a larger decline among NHB men ages 40-54 years. The NHB to NHW IRR for total prostate cancer increased from 1.73 (95% CI = 1.69 to 1.76) in 2011 to 1.87 (95% CI = 1.83 to 1.92) in 2012 and has remained elevated, driven by differences in localized tumor incidence. Metastatic disease incidence is rising across all racial and ethnic groups. Conclusions The frequency of prostate cancer screening varies by race and ethnicity, and there was a modestly steeper decline in PSA testing among younger NHB men relative to NHW men since 2012. The NHB to NHW IRR for localized prostate cancer modestly increased following 2012.

The Impact

211 Background: The United States Preventive Services Task Force (USPSTF) recommended against routine PSA based prostate cancer screening in all men in 2012. This led to dramatic reductions in screening and rates of localized disease across all clinical risk groups. We sought to study the impact of this on rates of metastatic disease, specifically by patient race and age. Methods: We analyzed new prostate cancer incidence by stage at diagnosis between 1988-2013 within the Cancer Registry of Greater California. We further stratified cases by four major race/ethnicity groups (non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic and non-Hispanic Asian/PI (API)) and age. Incidence rates were calculated and compared per 100,000 and age-adjusted to the 2000 US Standard Population. Joinpoint regression was used to detect changes in incidence and to calculate the average percent change (APC). Results: Adjusted rates of remote prostate cancer incidence for NHW men increased slightly in the most recent decade (+0.28%) after steady declines in previous years with the inflection point occurring in 2002, however this was not statistically significant. In contrast, incidence of remote prostate cancer continued to decline for NHB (-2.73%), Hispanic (-2.04%), and API (-1.45%) men. The greatest increase of +1.1% a year since 2002 was observed for NHW men under age 65. The incidence of localized prostate cancer declined for all race/ethnicity groups over the most recent time period and also declined in all age groups. After remaining relatively flat since 1992, incidence of localized prostate cancer among NHW men declined by over 8% per year starting in 2007 compared with a more gradual decline of -3.52% a year since 2000 for NHB, and more recent declines of -14.41% and -16.64% for Hispanic and API men, respectively. Incidence of regional stage cancer also declined in all groups, but less dramatically. Conclusions: Incidence rates of newly metastatic prostate cancer have not significantly changed since PSA screening declined in the US although we noted a slight upward trend primarily for younger, white men since 2002.

AbstractRecent prostate cancer screening trials have given conflicting results and it is unclear how to reduce prostate cancer mortality while minimising overdiagnosis and overtreatment. Prostate cancer testing is a partially observable process, and planning for testing requires either extrapolation from randomised controlled trials or, more flexibly, modelling of the cancer natural history.An existing US prostate cancer natural history model (Gulati et al, Biostatistics 2010;11:707-719) did not model for differences in survival between Gleason 6 and 7 cancers and predicted too few Gleason 7 cancers for contemporary Sweden. We re-implemented and re-calibrated the US model to Sweden. We extended the model to more finely describe the disease states, their time to biopsy-detectable cancer and prostate cancer survival. We first calibrated the model to the incidence rate ratio observed in the European Randomised Study of Screening for Prostate Cancer (ERSPC) together with age-specific cancer staging observed in the Stockholm PSA (prostate-specific antigen) and Biopsy Register; we then calibrated age-specific survival by disease states under contemporary testing and treatment using the Swedish National Prostate Cancer Register.After calibration, we were able to closely match observed prostate cancer incidence trends in Sweden. Assuming that patients detected at an earlier stage by screening receive a commensurate survival improvement, we find that the calibrated model replicates the observed mortality reduction in a simulation of ERSPC.Using the resulting model, we predicted incidence and mortality following the introduction of regular testing. Compared with a model of the current testing pattern, organised 8 yearly testing for men aged 55–69 years was predicted to reduce prostate cancer incidence by 0.11% with no increase in the mortality rate. The model is open source and suitable for planning for effective prostate cancer screening into the future.Author summaryA naïve perspective is that cancer screening is simple: people are screened, some cancers are detected early, and cancer mortality rates decline. However, the mathematics for screening becomes difficult quickly, it is hard to infer causation from observational data, and even large randomised screening studies provide limited evidence. Simulations are therefore important for planning cancer screening.We found an older US prostate cancer natural history model to be poorly suited for contemporary Sweden. We therefore re-implemented and re-calibrated the US model using data from Swedish registries.Our revised model, the Stockholm “Prostata” model, provides predictions similar to those observed in the detailed Swedish registers on prostate cancer incidence and mortality. By modelling the mechanisms of the screening effect, we can predict the benefits and harms under a range of screening interventions.
