Cytosteatonecrosis after breast accelerated conformational partial irradiation at 40 Gy in 10 fractions a week: multicentre prospective study

Conformational accelerated partial irradiation is always more often used but the optimal dose is not yet known. Therefore, the authors report an assessment of the cytosteatonecrosis rate within a multicentre prospective study which delivered 40 Gy over 5 days. They analyse and comment the results obtained on a range of more than 150 women treated for breast cancer. Results are discussed in terms of age, tumour size. The method resulted in an acceptable cytosteatonecrosis rate in comparison with other accelerated partial irradiation. But a more precise assessment of the toxicity rate requires further investigations. Short communication
