对于术前放疗对食管癌切除术后预后的影响，我们进行了分组对比观察。手术治疗的５８２ 例食管癌患者分为术前放疗加手术切除综合治疗组，１１６ 例；单纯手术治疗组４６６ 例。分组为选择性，认为肿瘤不能切除或切除难度较大的行术前放疗加手术切除综合治疗；能够切除的则行单纯手术治疗。术前放疗方法为６０ 钴远距离照射，剂量（ 组织量）４０００ Ｃ Ｇ Ｙ４ 周。结果表明术前放疗，能够提高手术切除率；不增加术后并发症；能够提高术后远期生存率；能够减少癌瘤外侵及淋巴结转移率；不影响术后食管的愈合能力。对病期较晚而仍能手术切除者，术前放疗加手术切除可能是最佳治疗方法。
For the effect of preoperative radiotherapy on the prognosis of esophageal cancer resection, we performed a group comparison observation. The 582 cases of esophageal cancer treated with surgery were divided into preoperative radiotherapy combined with surgical resection group, 116 cases, and 466 cases treated with surgery alone. The group was selective and considered that the tumor could not be resected or the removal of the more difficult preoperative radiotherapy combined with surgical resection combined treatment; the resection can be treated with simple surgery. The preoperative radiotherapy method was 60 Co long-distance irradiation with a dose (tissue amount) of 4000 C G Y 4 weeks. The results showed that preoperative radiotherapy can improve the surgical resection rate; does not increase postoperative complications; can improve the long-term survival rate after surgery; can reduce the rate of cancer invasion and lymph node metastasis; does not affect the ability of postoperative esophageal healing. For patients who are still able to undergo surgical resection later, preoperative radiotherapy plus surgical resection may be the best treatment.
