[Radiation therapy in inflammatory breast cancer]. / Radiothérapie des cancers du sein inflammatoires.

ABSTRACT

BACKGROUND: Inflammatory breast cancer accounts for 1-5% of all breast cancers. It is associated with a poor prognosis, because of an increased risk to develop metastases in comparison with all breast malignancies. The treatment is multimodal. We have evaluated the role of radiotherapy indications, techniques and impact for local control and overall survival. METHOD: The series of the literature with more than 40 patients irradiated for inflammatory breast cancer published since 1995 were analyzed. RESULTS: Chemotherapy was always delivered first. Adjuvant radiotherapy was associated with local control and overall survival at 10 years of 63-92% and 51-64 respectively. Without surgery, local control was 65% and overal survival 38% at 10years. Results of concomitant radiochemotherapy were reported the studies were heterogenous. Modalities of radiotherapy were detailed with respect to dose and fractionation, target-volumes and technical considerations (including bolus). CONCLUSION: The multimodal strategy comprises systematically radiotherapy with an evaluation of tumor response to maximise resecability.
