Post Mastectomy Hypofractionated Radiotherapy in High Risk Breast Cancer
2017年10月22日 更新者：Ahmed Ahm
A Prospective Phase 3 Clinical Trial Of Postmastectomy Hypofractionated Radiotherapy in High Risk Breast Cancer
The purpose of this study is to compare the efficacy and toxicities of hypofractionated radiotherapy with conventional fractionated radiotherapy in high risk breast cancer patients treated with mastectomy.
It's hypothesized that the efficacy and toxicities are similar between the two groups.
研究概览
详细说明
Eligible breast cancer patients with mastectomy and axillary dissection are divided into two groups: conventional fractionated (CF) radiotherapy of 50 Gray (GY) in 25 fractions within 5 weeks to ipsilateral chest wall and supraclavicular nodal region, and hypofractionated (HF) radiotherapy of 43.5 Gray (GY) in 15 fractions within 3 weeks to the same region.
During and after radiotherapy , the patients are followed and the efficacy and toxicities of radiotherapy are evaluated.
