目的探讨三维适形放疗(3DCRT)方式对食管癌术后食管气管沟淋巴结转移的治疗效果。方法以40例食管癌术后食管气管沟淋巴结患者作为研究对象,对其采用3 DCRT,常规分割,总剂量55~70Gy/28~35次,5~7周,统计分析患者近期疗效、临床症状、生存时间和不良反应。结果 40例患者全部完成治疗,近期疗效的总有效率高达75.0%;治疗后相比于治疗前临床症状明显缓解,组间差异具有统计学意义(P<0.05);患者的平均生存期达到30个月;不良反应较少。结论 3DRCT对治疗食管癌术后食管气管沟淋巴结转移具有良好的效果,且安全方便,值得临床推广。
Objective To investigate the therapeutic effect of three-dimensional conformal radiotherapy (3DCRT) on the esophageal carcinoma after esophageal tracheal lymph node metastasis. Methods 40 patients with esophagectomy and esophagectomy postoperative esophageal ditch lymph nodes patients were studied by 3 DCRT, conventional segmentation, the total dose of 55 ~ 70Gy / 28 ~ 35 times, 5 to 7 weeks, the statistical analysis of the patient’s short-term efficacy, clinical symptoms , Survival time and adverse reactions. Results All the 40 patients completed the treatment. The total effective rate of the short-term effect was as high as 75.0%. After treatment, the clinical symptoms were significantly relieved compared with those before treatment. The difference between the two groups was statistically significant (P <0.05). The average survival time was 30 Month; adverse reactions less. Conclusion 3DRCT has good effect on the esophageal tracheal tubal lymph node metastasis after esophagectomy, and is safe and convenient. It is worthy of clinical promotion.
