The authors review the value of radiotherapy in the multidisciplinary treatment of early (stage 0-II) breast cancer and describe past achievements, current scientific evidences and possible future prospects of clinical research. Results of randomized studies proved that conservative surgery with radiotherapy is equally effective to mastectomy for the treatment of in situ and invasive breast cancer, both in terms of local control and overall survival. In the nineties, findings of prospective clinical trials indicate that the use of irradiation in high-risk patients provides both a significant improvement in loco-regional control and survival rate. The magnitude of survival benefit with appropriate patient selection and radiotherapy technique is similar to that seen with adjuvant systemic therapy. Radiotherapy of early breast cancer is based on level I scientific evidences in the vast majority of cases. Remaining controversial issues are subjects of several ongoing international and Hungarian prospective randomized studies.
