180例Ⅱb期宫颈癌患者接受了不同治疗方法，比较其五年生存率。结果显示：单纯体外放疗组30．0％；术后放疗组62．5％；体外加腔内根治剂量放疗且80．1％；术前放疗组88．0％。术前放疗组与单纯体外放疗组及术后放疗组比较，（P<0．01），与体外加腔内根治剂量放疗组比较，（P>0．05）。结论：单纯体外放疗不宜作为宫颈癌治疗常规方法，术前体外加腔内放疗可能有助于生存率提高。
180 cases of stage IIb cervical cancer patients underwent different treatment methods, compared to its five-year survival rate. The results showed that: 30.0% in vitro radiotherapy alone group; 62.5% after radiotherapy group; in vitro radiotherapy plus radiotherapy and 80.1%; preoperative radiotherapy group 88.0%. The preoperative radiotherapy group was significantly lower than radiotherapy group and postoperative radiotherapy group (P <0.01), and compared with radiotherapy group (P> 0.05). Conclusions: External radiotherapy alone should not be used as a routine treatment for cervical cancer. Preoperative external plus intracavitary radiotherapy may help to improve the survival rate.
