The impact of adjuvant radiotherapy and cytotoxic chemotherapy on the outcome of immediate breast reconstruction by tissue expansion after mastectomy for breast cancer

In an attempt to evaluate the impact of radiation therapy and cytotoxic chemotherapy on the outcome of immediate breast reconstruction by tissue expansions after mastectomy a prospective study on 32 patients was performed. The radiation therapy significantly worsened the surgical outcome, because the irradiated patients more often had pectoral muscle stiffness making the expansion more painful and the reconstructed breast too small, hard and with insufficient ptosis to obtain a natural breast mould. These results indicate that this technique should be avoided in patients likely to receive postoperative adjuvant cytotoxic chemotherapy and radiation therapy, thus reducing the indication to a small group of patients undergoing mastectomy for widespread ductal carcinoma in situ.
