Marianne Ulcickas Yood, D.Sc., M.P.H., of Galt Associates, Sterling, Va., and colleagues determined the risk and the length of time between polypectomy and the return of polyps in 8,865 patients who were part of a large health maintenance organization (HMO) where colon cancer screening was a covered benefit.The participants were 50 years old or older and underwent a polypectomy between January 1, 1989, and December 31, 1999.Patients were followed up through September 1, 2001.
Of the 8,865 patients who underwent polypectomy, 2,704 patients (30.5 percent) were diagnosed as having recurrent polyps.After analysis, the researchers projected that an estimated 50 percent of patients will have a recurrence within 7.6 years.Among patients who underwent colon screening at least 9 months after their polypectomy (52 percent of the study group), the authors' analysis suggested that 50 percent would have a recurrent polyp within 3.9 years.

Dr. Marianne Yood from Galt Associates in Sterling, Virginia, and colleagues used the computerized database from a large health maintenance organization to identify recurrent polyps among 8865 individuals who underwent an initial polypectomy.
After a mean follow-up of 4.6 years, 30.5% of patients were diagnosed as having recurrent polyps, the authors report.Men were slightly more likely than women, and African-American patients were slightly less likely than others, to have a recurrence.
Kaplan-Meier projections indicated that half the patients who had an initial polyp would have a recurrence within 7.6 years and a quarter of the patients would have a recurrence within 3.3 years.An estimated 50% of patients would have a recurrence within 3.9 years, based on findings in the subset of patients who were rescreened at least 9 months after the index polypectomy.
"Efforts to increase and monitor ongoing screening of postpolypectomy patients and efforts to improve appropriate colorectal cancer screening activities are warranted," Dr. Yood
and colleagues conclude."In addition, further research is needed to better identify patients at risk for recurrence so that continued screening and other interventions can be targeted at these groups."
