Study: Multiple factors linked to interval colorectal cancer

A study of colorectal cancer diagnosed after a negative colonoscopy linked cases to a number of procedural and biologic factors. University Hospitals Case Medical Center researchers reported an overall prevalence of interval cancer of 7.2% in a study population of more than 57,000 patients aged 69 and older diagnosed with colorectal cancer. The analysis of Medicare patients showed increased comorbidity, proximal tumor location, previous diverticulosis and a history of polypectomy all were associated with interval cancer cases.
