Sarcoma of the chest wall is a relatively rare consequence of radiotherapy for breast cancer. Sarcoma treatment involves radical surgical resection of the tumour whenever possible.
The surgery is mostly followed by radiotherapy which, however, is impossible in a patient after breast-preserving surgery for carcinoma with radiotherapy. Chemotherapy is not very effective in sarcomas.
Therefore, the operation needs to be performed by an experienced surgeon in a sufficiently radical way.
