Effects of cellular repair and proliferation on targeted radionuclide therapy: a modelling study.
A previous targeted radionuclide therapy modelling study has been extended to include the radiobiological effects of cellular repair and proliferation. Dose distributions have been converted into biologically effective dose (BED) distributions using a previously published formulation. With suitable estimated parameters, corrected tumour control probability (TCP) values were derived. The dependence of BED on the physical half-life of the radionuclide was also modelled. Results indicate that the TCP is greater when a shorter physical half-life is employed.
