Years of life lost due to colorectal cancer in Poland between 2000 and 2014 according to voivodships

Background
Colorectal cancers (CRC s) are among the most important oncological causes of death in Europe. Poland belongs to countries where the mortality rates due to this cause exceed the average values for EU -28.

Objectives
Comparison of the number of years of life lost (YLL s) due to CRC between 2000 and 2014 in Poland by voivodships

Material and methods
The study was based on a dataset containing information from the death certificates of Poles who died in 2000 and 2014 (368,028 and 376,467 records, respectively). The data on deaths caused by CRC (C18–C21 according to IC D-10) was used for the analysis (8,517 deaths in 2000 and 11,411 deaths in 2014). SEYLL (Standard Expected Years of Life Lost) was implemented to assess YLL s.

Results
Results. In 2000, the highest number of YLL s per 10,000 men was recorded in Zachodniopomorskie (55.7 years), and in 2014 – in Opolskie (77.5 years). The increasing tendency of this measure between 2000 and 2014 in the group of men was observed in all voivodships. In the group of women, in 2000 the highest number of YLL s per 10,000 was reported in Lodzkie (46 years), and in 2014 – in Warminsko- Mazurskie (49.6 years). In women, an SEYLL p decline over time was noted only in Lodzkie and Dolnoslaskie, and in other voivodships, its values increased.

Conclusions
Between 2000 and 2014, an upward tendency of YLL s due to CRC was observed in Poland, though with territorial differentiation. It is advisable to search for more effective methods of reducing existing inequalities between individual provinces of Poland.
