Key Points

To evaluate key methodological concerns regarding exposure–outcome overlap, component redundancy, and the potential mediating role of molecular residual disease in the aging shock index for colorectal cancer surgery.
Conceptual and methodological appraisal of the aging shock index applied to surgical oncology outcomes.
Identifies unresolved methodological issues regarding redundancy among index components and potential overlap between surgical exposures and measured clinical outcomes.
Emphasizes the necessity of determining whether molecular residual disease acts as a biological mediator influencing post-surgical prognosis.
