就头颈癌而言,即使以前做了一个疗程的放疗,对其复发或放疗后的第二原发癌在无条件手术的情况下,再次放疗常是唯一可行的治疗手段。我们分析了Gustave Roussy研究所在1973～1981年中用再次放疗的35名病人的疗效。男31例,女4例。年龄20～78岁(平均54岁)。表皮样癌31例,纤维肉瘤、软骨肉瘤、浆细胞瘤和未分化癌各1例。第一次和第二次照射的病变部位数:咽—喉部分别为10和11例;口腔和口咽 In the case of head and neck cancer, even if a course of radiotherapy was previously performed, recurrence or radiotherapy after the second primary cancer in the absence of conditional surgery, re-radiotherapy is often the only feasible treatment. We analyzed the efficacy of 35 patients treated with re-radiotherapy in the Gustave Roussy Institute between 1973 and 1981. There were 31 males and 4 females. Age 20 to 78 (mean 54). There were 31 cases of epidermoid carcinoma, 1 case of fibrosarcoma, chondrosarcoma, plasmacytoma and undifferentiated carcinoma. Number of lesions on first and second irradiation: 10 and 11 pharynx and laryngeal respectively; mouth and oropharynx
