Increasing low risk prostate cancer incidence in United States Air Force servicemen and selection of treatments.

ABSTRACT: Periodic Health Assessments have been mandated for United States Air Force servicemen since the mid 1990s. Thus, we determined whether United States Air Force prostate cancer incidence rates increased thereafter and how these tumors segregate into low and intermediate/high risk categories. We also identified treatment choices.We queried the Department of Defense Automated Central Tumor Registry for prostate cancer diagnosed in United States Air Force servicemen between 1991 and 2008 to determine incidence rates, disease risk category and treatments.Age adjusted rates in white active duty servicemen diagnosed for the most recent period of 2005 to 2008 increased 3-fold relative to the rate in the earliest period of 1991 to 1994. A similar trend was evident in black servicemen. Relative to the Surveillance, Epidemiology and End Results population prostate cancer rates in active duty United States Air Force men between 1995 and 2008 were significantly increased for the 2 racial groups. A significantly greater proportion of active duty servicemen than retirees (62% vs 40%) presented with low risk disease, defined as prostate specific antigen less than 10 ng/ml, Gleason sum less than 7 and clinical stage T1a-T2a. Of those with low risk disease significantly more active duty servicemen elected curative surgery than retirees (93% vs 53%).Prostate cancer incidence rates in United States Air Force servicemen have increased with time, exceeding rates in the Surveillance, Epidemiology and End Results population. While most cases are characterized as low risk, aggressive management is elected.

Project description:Although annual mortality trends for prostate cancer were stabilized in recent years, understanding the exact treatment changes is necessary for optimal management. Utilization of not-otherwise specified (NOS) treatments for prostate cancer was unclear. Thus, this study aimed to analyze trends in treatment for prostate cancer in the U.S. from 2010 to 2015 and examine whether the treatment for the prostate cancer in the U.S. is compliant with clinical practice guidelines. Using joinpoint regression models, we examined trends in the rate and proportion of age-standardized utilization (ASUR and ASUP) of treatments for prostate cancer diagnosed during 2010-2015 in the U.S. based on the data from the Surveillance, Epidemiology, and End Results (SEER, 2018 data-release, with linkage to active surveillance/watchful waiting [AS/WW]) cancer registry program. Among 316,690 men with prostate cancer diagnosed during 2010-2015, ASUR and ASUP for radical prostatectomy, radiotherapy, AS/WW and NOS treatment were 32.7, 34.4, 10.0 and 40.1 per 100,000, and 27.9%, 29.3%, 8.5% and 34.2%, respectively. Trends in the overall ASUR for prostate cancer treatments differed by cancer risk group, patients' age, race/ethnicity, Gleason score, insurance status, and the average education level, average poverty-level and foreign-born person percentage of the patient's residence-county, but not by rural-urban continuum or region. ASUP of radical prostatectomy decreased from 9.8% in 2010 to 4.8% in 2015 (annual percent change [APC] = -12.0%, 95% CI, -15.9 to -7.9%), and the decrease was observed in all different risk groups. ASUP of AS/WW increased from 16.4% in 2010 to 30.2% in 2013 (APC = 22.7%, 95% CI, 4.6 to 44.0%) and then remained stable through 2013 to 2015 (APC = 1.9%, 95% CI, -24.1 to 36.9%). The increasing tendency of AS/WW only occurred in the low-risk and intermediate-risk groups. The ASUP of NOS treatment has increased from 32.3% in 2010 to 36.8% in 2015 (P<0.01). In conclusion, ASUR and ASUP for prostate cancer treatments, including NOS treatment, had changed during 2010-2015. Their trends appeared to differ by cancer risk-group, age, race/ethnicity, Gleason score and socioeconomic factors. Future studies are warranted to understand the impacts of upward trends in ASUP of NOS treatments and AS/WW on patient survival and prostate cancer mortality.

Project description:BACKGROUND:Prostate-specific antigen (PSA) testing has dramatically changed the composition of prostate cancer (PCa), making it difficult to interpret incidence trends. New methods are needed to examine temporal trends in the incidence of clinically significant PCa and whether trends vary by race. OBJECTIVE:To conduct an in-depth analysis of incidence trends in clinically significant PCa, defined as cases in which PCa was the underlying cause of death within 10 yr of diagnosis. DESIGN, SETTING, AND PARTICIPANTS:We extracted incident PCa cases during the period 1975-2002 and associated causes of death and survival through 2012 from nine cancer registries in the population-based Surveillance Epidemiology and End Results program database. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS:We applied joinpoint regression analysis to identify when significant changes in trends occurred and age-period-cohort models to examine longitudinal and cross-sectional trends in the incidence of fatal PCa. RESULTS AND LIMITATIONS:Among 51 680 fatal PCa cases, incidence increased 1% per year prior to 1992, declined 15% per year from 1992 to 1995, and further declined by 5% per year through 2002. Age-specific incidence rates of fatal disease decreased >2% per year among men aged ?60 yr, yet rates remained relatively stable among men aged ?55 yr. Fatal disease rates were >2-fold higher in black men compared with white men, a racial disparity that increased to 4.2-fold among younger men. CONCLUSIONS:The incidence of fatal PCa substantially declined after widespread PSA screening and treatment advances. Nevertheless, rates of fatal disease among younger men have remained relatively stable, suggesting the need for additional attention to early onset PCa, especially among black men. The persistent black-to-white racial disparity observed in fatal PCa underscores the need for greater understanding of the causes of this difference so that strategies can be implemented to eliminate racial disparities. PATIENT SUMMARY:We assessed how the incidence of ultimately fatal prostate cancer (PCa) changed over time. We found that the incidence of fatal PCa declined by >50% since the introduction of prostate-specific antigen testing and advances in treatment options; however, incidence rates among younger men remained relatively stable, and younger black men exhibited a 4.2-fold higher risk for fatal disease compared with white men.
