The usefulness of postoperative radiotherapy for breast cancer was investigated in 152 patients. A dose of 50 Gy was given to the axillar, supraclavicular and internal mammary lymphnode areas using a 12 MeV electron and to the chest wall using a 6 MeV electron. The five and 10-year survival rates were 79.1% and 50.8%, respectively. The five-year survival rates according to the TNM staging were 100% for stage I, 78.4% for stage II, 58.8% for stage III and 0% for stage IV. The local recurrence rate was 8.8%, the metastasis rate was 33.1% and the recurrence rate in the ipsilateral supraclavicular regions previously treated by prophylactic irradiation was 2.6%, while it was 8.9% in the ipsilateral chest wall.
对152例乳腺癌患者术后放疗的有效性进行了研究。使用12兆电子伏特的电子束对腋窝、锁骨上和内乳淋巴结区域给予50戈瑞的剂量，使用6兆电子伏特的电子束对胸壁给予该剂量。5年和10年生存率分别为79.1%和50.8%。根据TNM分期，I期的5年生存率为100%，II期为78.4%，III期为58.8%，IV期为0%。局部复发率为8.8%，转移率为33.1%，先前接受预防性照射的同侧锁骨上区域的复发率为2.6%，而同侧胸壁的复发率为8.9%。
