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."
