食管癌放疗的临床应用研究

目的食管癌放疗的临床应用研究。方法 102例食管癌术后患者均采用医用电子直线加速器采用6¹5MV-X线对食管癌患者进行放射治疗。用CT模拟定位,设三野或四野,无肿瘤残留者肿瘤照射剂量为50 Gy,有肿瘤残留者肿瘤照射剂量为6015MV-X线对食管癌患者进行放射治疗。用CT模拟定位,设三野或四野,无肿瘤残留者肿瘤照射剂量为50 Gy,有肿瘤残留者肿瘤照射剂量为60⁶6 Gy。肿瘤照射剂量控制在5066 Gy。肿瘤照射剂量控制在50⁶6 Gy。结果利用食管癌放疗治疗102例,有效研究病例102例,治疗后1年和3年局部控制率为69.6%和49%。结论食管癌放疗采用666 Gy。结果利用食管癌放疗治疗102例,有效研究病例102例,治疗后1年和3年局部控制率为69.6%和49%。结论食管癌放疗采用6¹5MV-X线照射,能够对除存在远处转移及严重并发症等病患以外的患者减轻痛苦,提高生存质量,延长生存期。

Clinical Study of Radiotherapy for Esophageal Carcinoma

Objective To analyze the changes and clinical application of radiotherapy of esophageal carcinoma after image.Methods 102 patients with esophageal carcinoma after operation were treated with medical electron linear accelerator with 6~15MV- X-ray of esophageal carcinoma patients treated with radiotherapy. Simulation with CT, with Sanye or the country, no tumor residual tumor dose was 50 Gy, with tumor residual tumor dose was 60~66 Gy. Tumor dose control in 50~66Gy.Results Treatment of 102 cases of the use of radiotherapy, effective on 102 cases, 1 years after treatment and 3 year local control rates were 69.6% and 49%.Conclusion Radiotherapy for esophageal cancer by 6~15MV-X-ray irradiation to patients, except for the presence of distant metastases and severe complications of patients to relieve pain, improve life quality, prolong the survival period.
