Incidence and mortality projections for major cancers among Korean men until 2034, with a focus on prostate cancer

Abstract

Purpose The Korean population is rapidly aging, and the cancer burden is expected to change significantly. This study aimed to generate projections of incidence and mortality of major cancers among men in Korea until 2034, with a special focus on prostate cancer. Materials and Methods Cancer incidence data from 1999 to 2016 were obtained from the Korea National Cancer Incidence Database. Mortality data were obtained from Statistics Korea. The most common cancers among Korean men (stomach, colorectum, liver, lung and prostate) were analyzed. To predict the future trends of these cancers, the age-period-cohort method was conducted and extrapolated up to 2034. Results In Korean men, prostate cancer was the fourth most commonly diagnosed cancer in 2016. Based on newly diagnosed cases, the leading cancer site in the year 2034 is expected to be the lung, and the prostate is expected to be the second most frequently diagnosed cancer among Korean men. Age-standardized incidence rates of the most common cancers in men, except prostate cancer, are expected to decrease until 2034. Lung cancer is projected to remain the most common cause of cancer-related mortality until 2034, and the highest estimated change in cancer deaths is expected to be for prostate cancer. Conclusions In Korea, the incidence and mortality of prostate cancer is expected to increase markedly in the period up to 2034, particularly in older men. Concerted efforts in screening, diagnosis, and treatment strategies should be considered by healthcare planners and providers.

The Short- and Long-Term Anticipation of Prostate Cancer Incidence in Korea: Based on Social Aging Trends and Prostate-Specific Antigen Testing Rate during the Last Decade

“…However, utilizing the same data source of the National Cancer Incidence database, Park et al anticipated that PCa would remain in second place among the most common male cancers by 2035, following lung cancer. The expected incidence of PCa in 2034 was 29,339 cases [22]. The International Agency for Research on Cancer (IARC) is an agency of the World Health Organization (WHO) responsible for managing and conducting the GLOBOCAN project that provides estimates of cancer incidence, mortality, and prevalence worldwide.…”

“…PC has been reported as the fourth most common cause of cancer globally. World health organization (WHO) estimated the prevalence of PC in 2018 as 1.3 million cases worldwide (Pak et al 2022 ). PC comes in second place as the most common cancer in men (13.5% of total cancer cases in men) after lung cancer (14.5%) (Maldonado Ortiz 2022 ).…”

“…한국은 급속한 고령화 사회로 진입하고 있으며, 이로 인해 전립선암과 관련된 사회경제적 부담이 증가할 것으로 예측된다( 1 ). 따라서 전립선암의 조기 발견과 정확한 진단의 필요성은 더욱 높아지고 있다( 2 ). 그럼에도 불구하고, 수십 년 동안 이 질환의 진단은 무작위적으로 전립선으로부터 생검을 하는 방식인 체계적 생검에 의존해 왔다.…”
