What Do Population-based Studies Tell Us about the Ideal Timing of Surgical Resection for Colorectal Cancer?

Timely access to curative-intent colorectal cancer (CRC) surgery is a central component of surgical quality. Yet contemporary evidence challenges historical assumptions that shorter wait times always confer better outcomes. Drawing on population-based studies which offer the most robust and generalizable data this article synthesizes what is known about the relationship between surgical delay and oncologic outcomes in CRC. We outline key conceptual considerations in defining wait-time intervals, discuss lessons from the coronavirus disease 2019 pandemic, and identify gaps for future research. Ultimately, wait times should be applied as flexible, evidence-informed quality indicators that support patient-centered, biologically sound, and operationally feasible cancer care.
