自1992年4月至1993年4月,采用前疗程常规分割放疗—后疗程超分割放疗方案对27例经病理证实的、不能手术切除的局部晚期非小细胞肺癌进行了临床初探。放疗后病人临床症状改善明显,肿瘤完全消退33.3％(9/27),部令消退37％(10/27),总有效率70.3％(19/27),较单纯全程常规分割为高。急性放射性肺炎和急性放射性食管炎乏主要的急性毒副反应。 From April 1992 to April 1993, 27 cases of locally advanced non-small cell lung cancer with pathologically confirmed local advanced non-small cell lung cancer (NSCLC) were treated with conventional segmented radiotherapy and post-treatment hyperfractionation radiotherapy. After the radiotherapy, the patient’s clinical symptoms improved significantly, the tumor completely resolved 33.3% (9/27), the department order regressed 37% (10/27), and the total effective rate was 70.3% (19/27), which was higher than the normal routine segmentation. Acute radiation pneumonitis and acute radiation esophagitis lack major acute toxicity.
