BackgroundThis study investigated trends in national expenditures on anticancer and immunomodulating agents from 2013 to 2022.MethodsInformation was obtained from the National Health Insurance claims data spanning a period of 10 years, from 2013 to 2022. The subjects of this study are patients diagnosed with cancer who used anticancer agents between January 1, 2013, and December 31, 2022. Trends were examined across various categories, including sex, age groups, routes of healthcare use, and types of healthcare institutions. We calculated the compound annual growth rate in both the number of patients and expenditures by year.ResultsIn 2013, pharmaceutical expenditures amounted to USD 11,984 million, representing 25.5% of the total healthcare expenditures, which were USD 46,984 million. Within this pharmaceutical expenditure, anticancer medications constituted USD 584 million, or 4.9%. By 2022, pharmaceutical expenditures had risen to USD 22,093 million, accounting for 22.8% of the total healthcare expenditures of USD 96,904 million. Of this amount, USD 1,566 million was allocated to anticancer drugs, which represented 7.1% of the total pharmaceutical expenditures. Between 2013 and 2022, total healthcare expenditures experienced a significant increase of 106.2%, reaching USD 49,920 million. Concurrently, pharmaceutical expenditures rose by 91.1% to USD 10,919 million, while expenditures on anticancer drugs surged by 168.2% to USD 982 million. In 2022, the category with the highest expenditures was ATC L01FF, which includes programmed cell death protein 1/death ligand 1 inhibitors such as nivolumab, totaling USD 266.2 million. This was followed by L01FD at USD 198.8 million and L01EA at USD 140.4 million. Since 2018, however, spending on immune checkpoint blockers targeting cell death proteins or ligands has continued to rise and currently ranks first.ConclusionThe number of patients using anticancer drugs and the associated drug expenditures have risen between 2013 and 2022. As the share of anticancer drugs in total drug expenditures grows, so too do the overall expenditures. This escalating financial burden highlights the necessity for policymakers to thoroughly understand the appropriate and cost-effective usage of anticancer drugs, as it directly influences the affordability and accessibility of healthcare services.© 2025 The Korean Academy of Medical Sciences.
