Individualization of dose prescription based on normal-tissue dose-volume and radiosensitivity data.
The aim of this paper is to illustrate the potential gain in tumor control probability (TCP) of prostate cancer patients by individualizing the prescription dose according to both normal-tissue (N-T) dose-volume and radiosensitivity data. ⋯ There is a potential gain (increase in local tumor control) from dose individualisation strategies based on both N-T dose-volume data and radiosensitivity (assuming that this is available). Dose prescription individualization based only on dose-volume data can be exploited provided that reliable N-T response models are available. There will be additional gains if some estimate of N-T radiosensitivity is available to allow further patient stratification, identification of patients with high radiosensitivity being particularly important.
