Background/objectives: Research on the relationship between small-area-level deprivation and cancer survival, particularly for colorectal cancer (CRC), is lacking. Therefore, we investigated the relationship among small area-level deprivation, individual-level factors, and CRC survival using data from the Busan Regional Cancer Registry.
Methods: We analyzed 34,999 patients with CRC from the Busan Regional Cancer Registry from 2003 to 2020.
