Summary
This review examines normal tissue complication probability (NTCP) models used in radiotherapy (RT). It highlights the assumptions, mathematical underpinnings, and limitations of empirical and mechanistic models for predicting radiation-induced late effects.
Area of Science:
- Radiation oncology
- Medical physics
- Biostatistics
Background:
- Radiotherapy (RT) necessitates accurate prediction of normal tissue complication probability (NTCP) to minimize adverse effects.
- Understanding NTCP is crucial for optimizing radiation treatment planning and patient outcomes.
Purpose of the Study:
- To provide a comprehensive overview of existing NTCP models for conventional radiotherapy.
- To critically analyze the assumptions, mathematical frameworks, and limitations of various NTCP modeling approaches.
Main Methods:
- Systematic review of empirical and mechanistic NTCP models.
- Analysis of the underlying mathematical formulations and biological assumptions.
- Evaluation of the strengths and weaknesses of each model type.
Main Results:
- Identified diverse NTCP models based on empirical and mechanistic principles.
- Detailed the mathematical translations and core assumptions of each approach.
- Highlighted the specific advantages and disadvantages inherent in different modeling strategies.
Conclusions:
- NTCP models are essential tools in radiotherapy, but their accuracy depends on underlying assumptions and model type.
- Further refinement of both empirical and mechanistic models is needed to improve prediction of radiation-induced late effects.
