The aim of the study was to analyze recurence of large intestine adenomas after polypectomy and its co-incidence with DNA microsatellite instability (MSI).Material and methods. Among 2880 patients who underwent polypectomy during colonoscopy in our department from June 2004 to February 2007 we revealed adenomas in 259 cases (8.99%). Then we chose 97 patients who agreed to participate in further study. Mean age of the group was 65.1 yrs. In these patiens we removed 207 adenomas of the large intestine. Within 90-360 days all of the patients underwent control colonoscopy in our department. All removed lesions were verified histologically and genetically to determine presence of microsatellite instability.Results. In 15 (17.4%) patients we revealed recurence of adenomas. Microsatellite instability was detected in 16 (18.6%) patients. The recurence of polyps was more frequent in patients with MSI (4 cases - 25%) than in patients without MSI (11 cases - 15.7%).Conclusions. In our opinion further study may help to determine the group of patients with faster adenoma recurence. In those cases more frequent colonoscopy may be justified.
