Comparative effectiveness of surveillance colonoscopy intervals on colorectal cancer outcomes in a national cohort of patients with inflammatory bowel disease.
The purpose of this study was to determine the comparative effectiveness of varying colonoscopy intervals on colorectal cancer (CRC) outcomes among patients with inflammatory bowel disease (IBD). Data was from the National Veterans Health Administration. Findings showed that, in a national cohort of patients with CRC-IBD, colonoscopy within 3 years prior to CRC diagnosis was associated with early tumor stage at diagnosis, and colonoscopy within 1 year was associated with a reduced all-cause mortality compared with no colonoscopy, supporting colonoscopy intervals of 1 to 3 years in patients with IBD in order to reduce late-stage CRC and all-cause mortality.

Population-based assessment of the association between magnetic resonance imaging background parenchymal enhancement and future primary breast cancer risk.
The purpose of this study was to evaluate comparative associations of breast magnetic resonance imaging (MRI) background parenchymal enhancement (BPE) and mammographic breast density with subsequent breast cancer risk. The investigators concluded that BPE was associated with future invasive breast cancer risk independent of breast density. They suggest that BPE should be considered for risk prediction models for women undergoing breast MRI.
