The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2019.
Incidence, survival, and prevalence rates of cancer were calculated using the Korea National Cancer Incidence Database, from 1999 to 2019, with survival follow-up until December 31, 2020. Deaths from cancer were assessed using causes-of-death data obtained from Statistics Korea.
In 2019, newly diagnosed cancer cases and deaths from cancer were reported as 254,718 (ASR, 275.4 per 100,000) and 81,203 (ASR, 72.2 per 100,000), respectively. For the first time, lung cancer (n=29,960) became the most frequent cancer in Korea, excluding thyroid cancer. The overall cancer incidence rates increased by 3.3% annually from 1999 to 2012, and decreased by 5.3% annually from 2012 to 2015, thereafter, followed by nonsignificant changes. The incidence of thyroid cancer increased again from 2016 (annual percentage change, 6.2%). Cancer mortality rates have been decreasing since 2002, with more rapid decline in recent years (annual decrease of 2.7% from 2002 to 2013; 3.3% from 2013 to 2019). The 5-year relative survival between 2015 and 2019 was 70.7%, which contributed to prevalent cases reaching over 2 million in 2019.
Cancer survival rates have improved over the past decades, but the number of newly diagnosed cancers is still increasing, with some cancers showing only marginal improvement in survival outcomes. As the number of cancer survivors increases, a comprehensive cancer control strategy should be implemented in line with the changing aspects of cancer statistics.
本研究提供了韩国 2019 年癌症的国家统计数据及其时间趋势，包括发病率、死亡率、生存率和患病率。
使用韩国国家癌症发病率数据库，从 1999 年至 2019 年计算癌症的发病率、生存率和患病率，生存随访截至 2020 年 12 月 31 日。使用韩国统计局的死因数据评估癌症死亡人数。
2019 年，新诊断癌症病例和癌症死亡人数分别为 254718 例（ASR，275.4/10 万）和 81203 例（ASR，72.2/10 万）。肺癌（n=29960）首次成为韩国最常见的癌症（不包括甲状腺癌）。1999 年至 2012 年，总体癌症发病率每年增长 3.3%，2012 年至 2015 年每年下降 5.3%，此后无显著变化。2016 年（年百分比变化，6.2%）甲状腺癌的发病率再次上升。自 2002 年以来，癌症死亡率一直在下降，近年来下降速度加快（2002 年至 2013 年每年下降 2.7%；2013 年至 2019 年每年下降 3.3%）。2015 年至 2019 年的 5 年相对生存率为 70.7%，这导致 2019 年患病病例超过 200 万例。
在过去几十年中，癌症生存率有所提高，但新诊断癌症的数量仍在增加，一些癌症的生存结果仅略有改善。随着癌症幸存者人数的增加，应根据癌症统计数据变化的各个方面实施综合癌症控制策略。
