Trends and characteristics of colorectal and breast cancer in Croatia and Osijek-Baranja County

This study analyzes long-term trends in incidence and mortality for colorectal cancer (CRC) and breast cancer (BC) at the national and regional (Osijek-Baranya County, OBC) levels.It provides an overview of preventive strategies and screening program outcomes.Data from the Croatian National Cancer Registry and the Osijek-Baranja County Cancer Registry were used to evaluate temporal changes from 2001 to 2023.Trends were assessed by joinpoint regression, expressed as Annual Percent Change (APC) with 95% confidence intervals.The results show a gradual decline in mortality from both cancers since 2010, more pronounced in women for breast cancer, and a moderate decrease in CRC mortality after 2015, particularly in regions with higher screening participation.
