Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) may put men at increased risk for colorectal cancer, a study found. The association was most prominent among men younger than 60 years.
Herng-Ching Lin, MD, of Taipei Medical University in Taiwan and collaborators conducted a study that included 2,899 men with colorectal cancer (cases) and 14,995 randomly selected men as controls. Case patients were 45% more likely than controls to have had a prior diagnosis CP/CPPS, after adjusting for hypertension, diabetes, renal disease, monthly income, geographic location and other potential confounders, the researchers reported online ahead of print in BJU International.
In a subgroup analysis, the association was strongest among men younger than 60 than other age groups. Case patients aged 40-49 and 50-59 were twice as likely as controls to have CP/CPPS.
