Dose-based evaluation of delineation variation in radiotherapy: A scoping review

Key Points

• This research aims to assess the variability in delineation methods used in radiotherapy and their impact on treatment outcomes.
• Conducted a scoping review of existing literature on dose-based evaluation methods.
• Analyzed the heterogeneity of delineation methods reported.
• Identified gaps regarding clinically meaningful delineation differences.
• Found significant variation in dose-based evaluation methods across studies.
• Consensus on clinically meaningful delineation differences is lacking.
• Reported dosimetric impacts of auto-segmentation showed inconsistency.
