Between 1966-1977, 250 patients with esophageal carcinoma were treated by radiotherapy alone. The 5-year survival rate was 10.4% (12 of 115) in the curative cases. 52 of 5-year survivors, including 40 cases from the literature, were analyzed according to age, sex and the extent, location and type of tumor. 37 patients (71.1%) were between 50 and 69 years of age. There were more female than male survivors. Patients whose esophagograms showed spiral-type tumor had a worse prognosis than other tumor types. 16 of the 52 (30.8%) patients had received intracavitary treatment. We posit that an additional boost dose by intracavitary techniques improves the local control of the primary lesion. Radiation-induced myelitis and carditis were noted in some patients.
1966年至1977年间，250例食管癌患者仅接受了放射治疗。治愈病例的5年生存率为10.4%（115例中的12例）。根据年龄、性别以及肿瘤的范围、位置和类型，对52例5年生存者进行了分析，其中包括文献报道的40例。37例患者（71.1%）年龄在50至69岁之间。女性生存者多于男性。食管造影显示为螺旋型肿瘤的患者预后比其他肿瘤类型更差。52例患者中有16例（30.8%）接受了腔内治疗。我们认为，通过腔内技术额外增加一次推量照射剂量可改善原发灶的局部控制。部分患者出现了放射性脊髓炎和心脏炎。
