title: Radiation therapy in operable breast cancer: results from the Stockholm trial on adjuvant radiotherapy.
abstract: In a randomized trial, 960 women with Stage 1-3 operable breast cancer were treated by a modified radical mastectomy alone, or by the same procedure, preceded or followed by radiotherapy (4500 rad to the breast/chest wall, and internal mammary, axillary and supraclavicular lymph nodes). Up to ten years after treatment, there is an increasing gap between the recurrence-free survival of the irradiated patients and the surgical controls. Between the two types of radiotherapy, there was no difference. There were significantly fewer distant metastases and a tendency for improved survival in node positive patients treated with postoperative radiotherapy, compared to the surgical controls, this difference was, however, statistically not significant.
