Detaljeret beskrivelse
Eligible breast cancer patients with mastectomy and axillary dissection are randomized into 2 groups:conventional fractionation radiotherapy of 50 Gy in 25 fractions within 5 weeks to ipsilateral chest wall and supraclavicular nodal region,and hypofractionation radiotherapy of 43.5Gy 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.
