【摘要】 我院于1964年5月至1978年12月采用⁶⁰Co治疗食管癌509例,其中病变位于中段者占74.66％,上段18.66％下段6.48％;病变长度大于5cm占69.16％。全组1、3、5年生存率分别为40.80％、16.11％、11.39％;而单纯放疗471例分别为39.07％,15.07％,10.62％;术前放疗21例分别为71.43％,42.86％,33.33％;术后放疗17例分别为29.41％,11.76％,5.88％。影响预后因素为:病变部位居于上段,病变长度≤5cm,定位准确,剂量6000至8000CGY,疗效较优。对中晚期食管癌,采用积极放疗加手术综合治疗,可以提高疗效。对足量（6,000CGy以上）放疗后X线检查病灶未消者加手术治疗,可以挽救部分病人生命。更多还原

【Abstract】 I A series of 509 cases of esophageal carcinoma were treatedwith tele-cobalt-60 radiotherapy at this hospital from May, 1964 to Dec., 1978. The age group of 40-59 years old was counted for 71.51%. Middle third segment of the esophagus was involved in 74.66% patients, respectively third segments were in 18.66%and 6.48%cases, respectively The lesions of 352 patients (69.16 %) were longer than 5cm in length. The 1, 3 and 5-year sur-vival rate were 40.8%. 16.11% and 11.39% in all cases after treatment, 39.07 %, 15.07% and 10.62% in 471 patients with radiotherapy only, 71.43%, 42.86% and 33.33% in 21 patients treated by pre-operative radiation but only 29.41%, 11.76 %, and 5.88%in 17 cases with post-operative radiation.The factors influencing prognosis has also been discussed in this paper. A better curative effect was obtained in patients whose lesion located in upper third segment and having 5 or less than 5 cm in length and in those received a dose of 6000- 8000cCy with a precisd localization of the target area. Operation combined with pre -late radiotherapy may improve the thera -pentic results in patients with middle -late stage especially in those with residue lesion after a radiation dose of more than dose 6000cCy.更多还原
