Postmastecomy Internal Mammary Nodal Irradiation for High-risk Breast Cancer Patients
Postmastectomy Prophylactic Internal Mammary Nodal Irradiation for High-risk Patients With Non-metastatic Breast Cancer
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Eligible patients are randomized into 2 groups: chest wall and supraclavicular nodal +-axillary plus internal mammary nodal irradiation, and chest wall and supraclavicular nodal +-axillary nodal irradiation. The prescription dose is 50 Gy in 25 fractions over 5 weeks or 43.5Gy in 15 fractions over 3 weeks.
During and after radiotherapy, the patients are followed and the efficacy and toxicities of radiotherapy are evaluated.
