A unified dose response relationship to predict high dose fractionation response in the lung cancer stereotactic body radiation therapy

Journal of Medical Physics, 2017
Aim: This study is designed to investigate the superiority and applicability of the model among the linear-quadratic (LQ), linear-quadratic-linear (LQ-L) and universal-survival-curve (USC) models by fitting published radiation cell survival data of lung ...

Dose response relationships for gamma radiation induced chromosomal instability [PDF]

, 2017
ABSTRACTDifferent cell lines demonstrate various dose response for radiation-induced chromosomal instability (RICI). To clarify the origin of differences we analyzed own and published data on RICI for four cell lines, V79, TK6, WTK1 and CHO-K1 on the basis of the mechanistic RICI model.

The Dose-response Relationships for Tumor Induction after High-LET Radiation.

Journal of Radiation Research, 1991
This paper presents a review of several studies conducted in our laboratory to examine the carcinogenic effects in mice of high-LET radiation and, for comparison, of low-LET reference radiation. For some specific end-points the following conclusions can be formulated: i) the dose-response curves for myeloid leukemia and malignant lymphoma can be ...
