Abstract: To explore the curative effects of preoperative concurrent chemoradiotherapy for Ⅱb cervical cancer. Methods:Fifty-eight cases with Ⅱb cervical cancer were divided into group A( 28 cases) and group B( 30 cases) . Group A and B were treated with chemotherapy and concurrent chemoradiotherapy before operation， respectively. The clinical effects，adverse reactions，operative time，blood loss，pathological features and recovery time of bladder function in two groups were analyzed. Results: The clinical effective rate in group B( 90. 00%) was higher than that in group A( 67. 86%) ( P ＜ 0. 05) . The differences of operative time，blood loss and recovery time of bladder function in two groups were not statistical significante( P ＞ 0. 05) . The preoperative chemoradiotherapy could decrease parametrial invasion and pelvic lymphnode metastasis ( P ＜ 0. 05). Conclusions: The preoperative concurrent chemoradiotherapy for Ⅱb cervical cancer can improve the clinical effects and resectable rate and decrease parametrial invasion and pelvic lymphnode metastasis，which is a practicable means.
