POSTOPERATIVE RADIATION THERAPY (RT) FOR BREAST CANCER CLINICAL ANALYSIS OF 314 CASES / 中华放射肿瘤学杂志

We analyzed retrospectively the result of postoperative RT by electron beam in 314 patients with breast cancer after a radical or modified mastectomy between 1976～1992. The radiation portals covered the supraclavicular, the axillary and the internal mammary lymph node chains and chest wall. D T40～50Gy/4～5w was delivered. The local regional failure and factors affecting the survival rates, such as the clinical stage, the status of axillary lymph nodes and radiation dose were analyzed. The symptomatic radiation pneumonitis (9.4%) was discussed.
