What does this research mean for the field?

While the impact of travel distance on cancer outcomes is mixed and moderated by sociodemographic factors, transportation barriers such as lack of vehicle ownership and inability to travel independently are consistently associated with worse cancer screening rates and later stage at diagnosis. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Scoping review evaluates transportation's role in cancer screening and diagnosis stage, suggesting improved measurement methods.

Key Points

To understand how transportation factors influence cancer screening and the stage at diagnosis.
Conducted a scoping review of quantitative observational studies from 2003 to 2025.
Included 53 studies on cancer screening and 43 on diagnosis stage, focusing on transportation barriers.
Two authors performed data extraction and quality assessment on the selected studies.
Travel distance/time accounted for 74% of analyses with mixed cancer outcome results based on distance.
Owning a vehicle and independent travel correlated with better clinical outcomes.
Quality assessment identified biases and neglect of data structure leading to potentially inflated effect sizes.
