PURPOSE For prostate cancer that is thought to be locally recurrent after prostatectomy, the optimal timing, dose and techniques for salvage radiotherapy (SRT) have not been established. Here we perform a systematic review of published reports including regression meta-analysis and radiobiologic modelling to identify predictors of biochemical disease control and late toxicity. METHODS We perf...
Background: Radiation-induced hypothyroidism (RHT) is one of the side effects that might have an impact on quality life patients with breast cancer treated radiotherapy. Objectives: The aim current study was to evaluate performances Lyman-Kutcher-Burman (LKB) and Log-Logistic models in prediction (HT) as well estimation model parameters for incidence RHT among cancer. Methods: Fifty-two radiati...
In order to study the radiobiological effects of low dose radiation, microbeam irradiation facilities have been developed in the world. This type of facilities now becomes an essential tool for studying bystander effects and relating signaling phenomena in cells or tissues. This review introduces you available microbeam facilities in Japan and in China, to promote radiobiology using microbeam p...
Brachytherapy treatment is primarily used for the certain handling kinds of cancerous tumors. Using radionuclides study tumors has been studied a very long time, but introduction mathematical models or radiobiological made planning easy. helps to compute survival probabilities irradiated tissues and cancer cells. With expansion using HDR-High dose rate LDR-low cancer, it requires fractionated d...
