Trends in United States Prostate Cancer Incidence Rates by Age and Stage, 1995-2012

Area of Science:

• Oncology
• Public Health
• Epidemiology

Background:

• Prostate-specific antigen (PSA) testing increased prostate cancer incidence significantly in the late 1980s.
• Guidelines issued around 2000 recommended against routine PSA screening due to concerns about overdiagnosis and overtreatment.
• This study examines prostate cancer incidence trends, including late-stage diagnoses, from 1995 to 2012.

Observation:

• Localized/regional prostate cancer incidence rates have declined since 2001, with a sharp decrease between 2010 and 2012.
• Distant-stage prostate cancer incidence rates declined overall since 1995, but showed varied trends across different periods.
• While distant-stage rates decreased in older men (70+), they increased in younger men (50-69) from 2004 to 2012.

Findings:

• Declining localized/regional prostate cancer incidence correlates with guidelines advising against routine screening.
• Incidence rates of distant-stage prostate cancer are rising among men aged 50-69.
• The study utilized joinpoint regression analysis on Surveillance, Epidemiology, and End Results (SEER) data, stratifying by age groups.

Implications:

• The rise in distant-stage prostate cancer in younger men may negatively impact future mortality rates.
• Continued monitoring of prostate cancer trends and screening practices is crucial.
• Understanding these trends is vital for refining screening recommendations and public health strategies.
