USA: A recent cohort study published in JAMA Network Open has revealed that delays in initiating colorectal cancer treatment were associated with a higher risk of metastasis, with the impact varying across different treatment pathways. Although timely treatment is considered an important component of colorectal cancer (CRC) management, the duration of delay that may adversely affect outcomes has remained uncertain. Longer time-to-treatment initiation was associated with a higher risk of metastasis, with the delay threshold varying according to the treatment pathway. The researchers suggested that a single treatment initiation benchmark may not be suitable for all colorectal cancer patients, recommending pathway-specific timelines to improve outcomes and optimize healthcare delivery.
