[Value of radiotherapy in breast cancer. Breast preservation rises to 80%]. / Stellenwert der Strahlentherapie beim Mammakarzinom. Brusterhaltung in bis zu 80%!

ABSTRACT

The indication for radiotherapy for mamma carcinoma is determined in particular by the macroscopic and microscopic tumor findings, the number of lymph nodes identified, receptor status, the surgical report and (neo)adjuvant chemotherapy. Irradiation is applied in particular in conjunction with breast-preserving first-line treatment in the case of ductal in situ carcinomas, and postoperatively following breast conservation in the case of invasive mamma carcinoma. The indication for irradiation following mastectomy is controversial and is determined by tumor size and location, together with further factors (see the Guidelines of the German Society of Senology). The indications applying to the irradiation of regional lymph nodes are determined by the sites of the respective metastases. The combination of radio- and chemotherapy is carried out in close cooperation between oncologists and radiologists.
