对原发性肺癌手术切除后纵隔预防照射的疗效进行分析。方法 :收集经纵隔淋巴结清扫 (均经病理证实有纵隔淋巴结癌转移 )且无肉眼可见残存病灶的Ⅲ期N2 肺癌 12 6例 ,分析术后预防性照射与否以及其他因素对预后的影响。结果 :术后纵隔预防照射组的 5年生存率为 19.0 % ,单纯手术组为 17.6 % ,两组之间无显著差异 ;该文还比较术后预防性照射在不同病理组织学类型、不同开胸侧别、隆突下淋巴结有否转移对生存率的影响 ,结果表明各因素两组间差别亦无统计学意义。结论 :术后预防性照射不宜一概而论 ,而应慎重进行 ,并提出了术后预防性照射的适用范围。
The curative effect of prevention of mediastinum after resection of primary lung cancer was analyzed. Methods: One hundred and sixty-six patients with stage Ⅲ N2 lung cancer who had undergone mediastinal lymph node dissection (pathologically confirmed mediastinal lymph node metastasis) and no residual lesions were collected. The effect of postoperative prophylactic exposure and other factors on prognosis were analyzed. Results: The 5-year survival rate of postoperative mediastinal irradiation prevention group was 19.0%, while that of the simple surgery group was 17.6%, there was no significant difference between the two groups. Preventive radiation was also compared in different histopathological types, Chest side, lymph nodes subluxed metastasis on the impact of survival, the results show that the differences between the two groups were not statistically significant. Conclusion: Prophylactic postoperative irradiation should not be generalized, but should be cautious, and put forward the scope of postoperative prophylactic irradiation.
