Gedetailleerde beschrijving
Investigators hypothesize that hypofractionated radiotherapy is equal effective and safe as conventional radiotherapy in breast cancer patients undergoing regional nodal irradiation.
Eligible breast cancer patients are randomized 1:1 into the following two groups:
- Hypofractionated therapy: 40 Gy in 15 fractions of 2.67 Gy in breast or chest wall and nodal drainage with Concurrent boost 48.0 Gy / 3.2 Gy daily in tumor bed, in case of conservative surgery;
- Standard fractionation: 50 Gy in 25 fractions in breast or chest wall and nodal drainage with sequential tumor bed boost with 10 Gy in 5 fractions in tumor bed in case of conservative surgery.
Patients will be followed for 6 months after radiotherapy to evaluate acute toxicity and quality of life.
