Metastatic prostate cancer (PCa) has been increasing in incidence since 2007, particularly among men in an age group believed most likely to benefit from definitive treatment, according to a new report.
Using the National Cancer Data Base (2004–2013), researchers led by Edward M. Schaeffer, MD, of the Northwestern University Feinberg School of Medicine in Chicago, identified 767,550 men diagnosed with PCa at 1089 different healthcare facilities in the United States. Of these, 3% had metastatic disease at diagnosis.
From 2007 to 2013, the incidence of metastatic PCa increased by 7.1% annually, the investigators reported online ahead of print in Prostate Cancer and Prostatic Diseases.In 2013, the incidence was 72% higher than in 2004. The greatest incidence of metastatic PCa was found among men aged 55–69 years (a 92% increase from 2004 to
2013). The incidence of low-risk PCa decreased by 9.3% annually from 2007 to 2013, and was 37% lower than in 2004.
