目的 :探讨超长食管癌放射治疗的价值及影响预后因素。方法 :1985年 3月～ 1992年 12月收治超长食管癌 12 0例 ,均采用60 Co外照射 ,DT60～ 70Gy。结果 :治疗后的 1、3、5年生存率分别为 30 %、6.7%、5.8% ;病变 <11cm和≥ 11cm的 5年生存率分别为 7%、0 ;疗终X线表现基本消失与部分消失的 5年生存率分别为 13.7%、0 (P <0 .0 5) ;超长食管癌的锁骨上淋巴结转移率 2 4 .2 % ,明显高于同期食管癌锁骨上淋巴结转移率 13.5% (P <0 .0 1)。结论 :超长食管癌应积极治疗 ,食管癌锁骨上淋巴结转移率及远处转移率与病灶长度呈正相关 ,食管病灶长度、疗终X线表现、放疗剂量是影响预后的主要因素
Objective: To investigate the value of radiation therapy for long esophageal cancer and prognostic factors. Methods: From March 1985 to December 1992, 120 patients with super long esophageal cancer were treated with 60Co external irradiation and DT60 ~ 70Gy. Results: The 1, 3, 5-year survival rates after treatment were 30%, 6.7% and 5.8% respectively. The 5-year survival rates of lesions <11cm and ≥ 11cm were 7% and 0 respectively. The 5-year survival rates of partially disappeared were 13.7% and 0 (P <0.05) respectively. The supraclavicular lymph node metastasis rate of super-long esophageal cancer was 24.2%, which was significantly higher than that of supraclavicular lymph node metastasis of esophageal cancer % (P <0 .0 1). Conclusion: Long esophageal cancer should be actively treated. The supraclavicular lymph node metastasis rate and distant metastasis rate of esophageal cancer are positively correlated with the length of the lesion. The length of the esophageal lesion, final radiographic X-ray findings and radiation dose are the main factors affecting the prognosis
