Abstract
INTRODUCTION: Colorectal cancer (CRC) in Podkarpackie in Poland is the third most common cancer in males (12.6% cancer diagnoses), and second among women (10.1% of recognised cancers). AIM: An analysis of the trends in CRC incidence in the years 1963-2014 in Podkarpackie in the south-east of Poland. MATERIAL AND METHODS: A total of 19,460 CRC cases recorded in the period 1963-2014 in the National Cancer Registry as ICD C18-C21 cases were analysed. RESULTS: The overall cancer incidence rate in Podkarpackie Province was 20.4 in men and 16.8 in women per 100 thousand, and was lower than the Polish population by 12.4% for men and by 17.6% for women, respectively, in comparison to general Polish population rates. The mean age of CRC diagnosis grew from 64.0 years in males and 64.5 years in females in 1963-1969 to 67.6 and 68.4 years in 2010-2014, respectively. CONCLUSIONS: In 1964-2014 the CRC incidence rate in the Podkarpackie region increased 12.7-fold in males and 8.1-fold in females. There was an observed stable growth of average annual increase in the CRC incidence rate in men in 1963-1999, but since 2000 a decline in this rate has been observed. In females there was a tendency towards increased average CRC incidence rate in Podkarpackie since 2000, while in the whole country the female population presented a stable decrease of this coefficient.
