肺癌已非手术适应症时,放射治疗仍有治愈的可能性。作者报告197例肺癌,以鳞状细胞癌最多,未分化癌次之,腺癌最少。按生存曲线观察,1年半后曲线变平。肿瘤复发或转移半数在放疗后4个月以内出现,15个月以后出现者较少。若将治疗后2个月内失败者排除不计,则局部控制率1年时为52%,2年时为47.1%。局部复发但未出现远处转移者本组有49例,对于此类患者如改善放疗技术,有可能使局部控制有所改进。
When lung cancer has been non-surgical indications, radiotherapy is still possible. The authors reported 197 cases of lung cancer, with most squamous cell carcinomas, followed by undifferentiated carcinomas, and the least adenocarcinomas. Observed by the survival curve, the curve flattens after one and a half years. Tumor recurrence or metastasis occurred within 4 months after radiotherapy, and less than 15 months later. If the loser within 2 months after treatment is excluded, the local control rate is 52% at 1 year and 47.1% at 2 years. Local recurrences but no distant metastases occurred in 49 patients in this group. For such patients, the improvement of radiotherapy techniques may improve local control.
