Use Of Epidemiological Analyses In Development Of Colorectal Cancer Clinical Practice Guidelines In The Czech Republic

Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the fourth most common cause of cancer death worldwide. Crucial in CRC as well as for other effective diagnostics and treatment is the knowledge translation and implementation of the current best available evidence into clinical practice and public health. Clinical practice guidelines are one of the useful tools to be able to improve diagnostics and increase survival rate.The epidemiological analysis was performed based on the data of the Czech National Cancer Registry from 1977 to 2017. We have analysed incidence, prevalence, mortality and primary treatment of CRC in the Czech Republic.The incidence of CRC increased significantly from 1982 to 2002 and is higher in men compared with women based on the data from the National Health Information System in the Czech Republic. The majority of the patients with CRC were diagnosed in early stages. Women were diagnosed at slightly higher age than men. An increase in surgical therapy performed in primary treatment of early CRC was reported from 2006 to 2016. Relative time of survival increased in reported patients with CRC.This analysis reported significant changes in incidence of CRC in the last 40 years as well as in diagnostics and primary therapy in early stages of CRC in the last 12 years. The first ever evidence-based clinical practice guideline on diagnostics and therapy of early CRC in the Czech Republic was developed and disseminated.
