TCP
Pronunciation: T-C-P
Also written as: TCP — Tumor Control Probability
Tumor Control Probability - mathematical model predicting likelihood of local tumor eradication.
Full Definition
Tumor Control Probability (TCP) is a radiobiological model that estimates the statistical likelihood of achieving local tumor control based on radiation dose, fractionation schedule, and tumor characteristics. TCP models incorporate factors such as tumor cell number, radiosensitivity, repopulation kinetics, and dose distribution heterogeneity to predict treatment outcomes. These models are valuable tools for treatment plan optimization, dose escalation studies, and comparative effectiveness research, providing quantitative frameworks for balancing tumor control probability against normal tissue complication probability in radiation therapy decision-making.
Usage
Usage note: Typically used as acronym in clinical contexts; spell out on first use in formal documents.
