Background: Modern radiotherapy requires accurate contouring which may suffer in the postsurgical setting. We estimated post-prostatectomy interand intra-rater contouring reliability and assessed the effect on bladder and rectal normal tissue complication probability (NTCP). Methods: Four physicians each contoured two different treatment plans, separated by at least seven days, on 15 patients r...

The normal tissue complication probability (NTCP) is a measure for the estimated side effects of a given radiation treatment schedule. Here we use a stochastic logistic birth-death process to define an organ-specific and patient-specific NTCP. We emphasize an asymptotic simplification which relates the NTCP to the solution of a logistic differential equation. This framework is based on simple m...

INTRODUCTION The dose-volume effect of radiation therapy on breast tissue is poorly understood. We estimate NTCP parameters for breast fibrosis after external beam radiotherapy. MATERIALS AND METHODS We pooled individual patient data of 5856 patients from 2 trials including whole breast irradiation followed with or without a boost. A two-compartment dose volume histogram model was used with b...
