Postoperative strahlentherapie beim mammakarzinom

An adequate postoperative radiation therapy reduces the locoregional recurrence risk after a breast cancer surgery to about one third to one fifth of the risk, which is present without radiotherapy. The local relapse is an independent prognostic factor. During the last years there has been an increasing number of hints, that the postoperative radiotherapy has a significant influence on the long-term survival rates due to an improved locoregional tumor control. Therefore, a radiation therapy is basically induced in the case of a large local relapse risk, i.e. after all surgeries which save the breast and after mastectomy in advanced stages (pT3-4 or extensive LC infestation). The risk of a modern radiation therapy is low.
