Estimates of Alpha/Beta (α/β) Ratios for Individual Late Rectal Toxicity Endpoints: An Analysis of the CHHiP trial.
Abstract
Changes in fraction size of external beam radiotherapy (EBRT) exert non-linear impacts on subsequent toxicity. Commonly described by the linear-quadratic model, fraction size sensitivity of normal tissues is expressed by the α/β ratio. Here we study individual α/β ratios for different late rectal side effects after prostate EBRT.
