Abstract

Purpose
This study aimed to report the projected cancer incidence and mortality for the year 2020 to estimate Korea’s current cancer burden.
Materials and Methods
Cancer incidence data from 1999 to 2017 were obtained from the Korea National Cancer Incidence Database, and cancer mortality data from 1993 to 2018 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against observed years and then by multiplying the projected age-specific rates by the age-specific population. A Joinpoint regression model was used to determine the year in which the linear trend changed significantly; we only used the data of the latest trend.
Results
In total, 243,263 new cancer cases and 80,546 cancer deaths are expected to occur in Korea in 2020. The most common cancer site is expected to be the lung, followed by the stomach, thyroid, colon/rectum, and breast. These five cancers types are expected to represent half of the overall burden of cancer in Korea. The most common type of cancer among people who die is expected to be lung cancer, followed by liver, colon/rectal, pancreatic, and stomach cancers.
Conclusion
The incidence rates for all types of cancer in Korea are estimated to decrease gradually. These up-to-date estimates of the cancer burden in Korea could be an important resource for planning and evaluating cancer-control programs.
