Introduction: Colorectal cancer is one of the most common cancers in both sexes and is one of the leading causes of death in Poland and the world. An effective method to prevent the development of colorectal cancer (CRC) is the detection of polyps during a screening colonoscopy and their removal. Objective: The aim of the study was to evaluate results of screening for early detection of colorectal cancer by colonoscopy. Material and methods: The study was based on analysis of medical records of 7965 patients who underwent colonoscopy as part of the National Screening Program (NSP) for Early Detection of Colorectal Cancer in the 2000–2014 period. Results: Polyps were removed in 2900 (36.4%) patients, among whom 1885 (23.6%) had adenomas, which were more frequent in men (32.9%). Tubular adenomas were observed in 1685 patients (21.1%), tubulo-villous adenomas were detected in 157 patients (2%) and villous adenomas – in 43 (0.5%) of them. Sixty-three (0.79%) colorectal cancers were detected in various clinical stages, including adenocarcinoma in situ in 3 patients. Probability of 5-year survival rate of colorectal cancer amounted to 74% while 10-years survival was reached in 63% of patients. Conclusions: The detection rate of polyps, adenomas and carcinomas thanks to screening colonoscopy was 36.4%, 23.6% and 0.79% respectively, while the probability of 5-year survival was 74%. An improvement in the quality of colonoscopy was observed in subsequent years of the NSP, which translated into better detection of adenomas.
