[摘要] 目的 探讨小剂量紫杉醇周疗联合放疗与单纯放射治疗中晚期宫颈癌的疗效和毒副反应。 方法 回顾性分析我院近年来收治的144例中晚期宫颈癌患者的临床资料。两组同样的放疗方法及剂量,同步放化疗组给予紫杉醇40 mg/m2周疗,共6次,比较两组的治疗效果及不良反应。 结果 同步放化疗组的有效率、3年生存率、局部复发率、远处转移率分别为90.8%、77.8%、11.8%、7.9%,单纯放疗组的有效率、3年生存率、局部复发率、远处转移率分别为69.1%、57.7%、20.6%、16.2%,两组差异有统计学意义(P<0.05)。两组不良反应发生率差异无统计学意义(P>0.05)。 结论 放疗加紫杉醇周疗能提高中晚期宫颈癌的疗效和生存率,毒副反应与单纯放疗组相比无明显增加。

[Abstract] Objective To investigate the efficacy and side effects of low-dose paclitaxel weekly therapy combined with radiotherapy and radiotherapy alone for middle and advanced cervical cancer. Methods The clinical data of 144 patients with middle and advanced cervical cancer admitted in our hospital in recent years were retrospectively analyzed. The same radiotherapy method and dose were given in the two groups. The concurrent radiotherapy and chemotherapy group was given paclitaxel 40 mg/m2 weekly therapy for a total of 6 times. The therapeutic effects and adverse reactions of the two groups were compared. Results The effective rate, 3-year survival rate, local recurrence rate, and distant metastasis rate of the concurrent radiotherapy and chemotherapy group were 90.8%, 77.8%, 11.8%, and 7.9%, respectively. The effective rate, 3-year survival rate, local recurrence rate, and distant metastasis rate of the radiotherapy group were 69.1%, 57.7%, 20.6%, and 16.2%, respectively. The difference was statistically significant between the two groups(P<0.05). There was no significant difference in the incidence of adverse toxic side effects between two groups(P>0.05). Conclusion Radiotherapy and paclitaxel weekly therapy can improve the efficacy and survival rate of middle and advanced cervical cancer, and the toxicity and side effects of the combined treatment are not significantly increased compared with those in the radiotherapy alone group.

宮颈癌是最常见的妇科恶性肿瘤之一,近年来发病率无明显下降趋势,发病年龄逐渐年轻化,部分患者发病时已经处于局部晚期,严重危害了女性的身心健康[1-2]。手术和放疗是主要的治疗方法,中晚期宫颈癌的治疗效果差,5年生存率为40%~50%[3],主要原因是远处转移和局部复发。近年来,随着新化疗药物的不断开发及给药途径和方法的改进,化疗已逐渐成为宫颈癌综合治疗的一个重要组成部分。紫杉醇是一种广谱抗肿瘤药物,在宫颈癌治疗方面的研究也倍受关注[4-7]。本研究采用小剂量紫杉醇每周化疗联合放疗治疗局部晚期宫颈癌患者,现报道如下。

1 资料与方法

1.1 一般资料

对2007年1月~2010年1月本院收治的144例一般情况均良好,无明显心、肝、肾功能异常的初治局部晚期宫颈癌患者的临床资料进行回顾性分析,所有病例均经宫颈活检病理确诊。其中同步放化疗组76例,年龄27~79岁,中位年龄57.5岁,病理类型为鳞癌70例,腺癌6例,根据国际妇产科联盟(international federation of gynecology and obstetrics,FIGO)标准,临床分期Ⅱb期30例,Ⅲ期43例,Ⅳa期3例。单纯放疗组68例,年龄34~81岁,中位年龄60岁,病理类型为鳞癌65例,腺癌3例,FIGO临床分期Ⅱb期35例,Ⅲ期32例,Ⅳa期1例。两组患者的年龄、分期和病理类型差异无统计学意义(P>0.05),具有可比性。

本院减少化疗药物剂量及缩短化疗间隔时间并同步放疗,降低了住院费用及时间,减少了药物毒性,提高疗效。因此,本研究认为,使用小剂量紫杉醇(40 mg/m2)每周化疗联合放疗可提高近期疗效及3年生存率,且并不增加毒副反应,不失为一种较有发展景途的治疗方法,但最佳的宫颈癌化疗药物及剂量仍有待进一步对比研究。
