放射治疗是肺癌局部治疗的重要方法之一, 近年来放射治疗技术有了很大的进步和提高, 照射技术已经从传统的二维常规放射治疗发展到了今天的精确放射治疗。精确放疗的实施主要表现在精确定位、精确计划、精确治疗三个方面的精度控制, 可以在不增加正常组织损伤的前提下增加肿瘤的照射剂量, 从而提高局部控制率和(或)提高患者的生活质量, 这要求除了减少系统误差, 还要求减少各阶段的随机误差[1]。在肺癌的放射治疗中, 呼吸运动的影响最大, 放疗时要考虑到整个呼吸周期中肺癌的位置变化。为解决呼吸补偿的问题, 我院于2010年1月~2010年12月采用呼吸门控技术放射治疗非小细胞肺癌(non-smallcelllungcancer, NSCLC)患者16例, 现将初步结果报道如下。

摘要:
目的 观察非小细胞肺癌呼吸门控放疗的近期疗效以及急性放射性肺炎发生率。 方法 16例病理明确的非小细胞肺癌患者采用呼吸门控放射治疗,总剂量60 Gy,分30次照射,观察放疗后肿瘤退缩情况及放射性肺损伤。 结果 近期总有效率为68.75%,5例患者发生II级放射性肺炎,其他患者均为0~1级放射性肺炎。 结论 呼吸门控放疗有较好的近期疗效,放射性肺炎的不良反应轻。 Abstract:Objective To observe the effect and acute radiation pneumonitis of respiratory gatedradiotherapy for non-small cell lung cancer patients. Methods Sixteen non-small cell lung cancer patientsreceived 3D conformal respiratory gating radiotherapy.The total dose is 60 Gy (2Gy/fraction). Results Therecent total effective rate was 68.75%, 5 cases have ll degree acute radiation pneumonitis, the other caseshave no obvious acute radiation pneumonitis. Conclusion Respiratory gated radiotherapy is safe and properfor non-small cell lung cancer patients. -
