To examine the incidence of interval colorectal cancer (CRC; diagnosed 6–59 months postcolonoscopy) across racial/ethnic groups in the U.S., researchers analyzed claims data among Medicare patients aged 66–75 years. Results were as follows:
Rates of interval CRC were 7.1% in black patients, 5.8% in white patients, 4.4% in Hispanic patients, and 3.8% in Asian patients. Relative to whites, the risk for interval cancer was higher in blacks (hazard ratio, 1.3) and lower in Asians (HR, 0.7).
Blacks had an elevated risk after both screening and nonscreening colonoscopies.
The colonoscopist's polyp detection rate (PDR) was inversely associated with interval CRC risk, and blacks were more likely to undergo colonoscopy by a doctor with a lower PDR (i.e…
