1980年1月至1991年12月,511例非小细胞肺癌术后,切除彻底且No者258例,72例作术后放疗,186例未放疗为对照组;切端残留或(和)N_(1-2)者253例,227例术后放疗,26例未行放疗。结果显示。术后残留或(和)N_(1-2)者经放疗可显著提高1、3和5年局部控制率和生存率(P<0.01),切除彻底且No者经术后放疗未能提高局部控制率,反而降低患者1年和3年生存率(P<0.05)。单纯切端残留经术后放疗的1、3和5年生存率要比N_(1-2)者为好(P=0.06～0.07)。
From January 1980 to December 1991, 511 cases of non-small cell lung cancer were treated with complete excision and 258 cases were No. 72 cases were treated by postoperative radiotherapy. 186 cases had no radiotherapy as the control group; residual and/or N_ 1-2) of 253 cases, 227 cases of postoperative radiotherapy, 26 cases did not perform radiotherapy. The results show. Residual or (and) N_(1-2) patients after radiotherapy can significantly improve the local control rate and survival rate (P<0.01) in 1, 3, and 5 years. The resection was thorough and no postoperative radiotherapy could improve the local The rate of control reduced the patient’s 1-year and 3-year survival rates (P<0.05). The 1-, 3-, and 5-year survival rates of residual radiosurgery after residual radiotherapy alone were better than those of N_(1-2) (P = 0.06 to 0.07).
