子宫颈鳞癌复发患者化疗的临床分析

Clinical Analysis of Chemotherapy on Recurrent Squamous Carcinoma of the Cervix: A Review of 54 Cases

  • 摘要: 目的:探讨有效的治疗复发宫颈癌患者的化疗方案。方法:回顾性分析中国医学科学院肿瘤医院1998年1 月至2007年12月治疗54例宫颈癌复发的治疗情况。结果:54例复发患者中,11例为根治术后复发,43例为放疗(包括术后放疗)后复发,照射野内复发患者24例;照射野外复发(包括初次手术后未行辅助放疗的复发患者)30例。复发诊断时平均年龄为(46.7 ± 1.442)岁(27~70岁),中位年龄45岁。距初次治疗结束后的平均复发时间为(13.80±2.344)个月(3~96个月),中位复发时间8 个月。54例患者中,43例SCC 升高,升高比例达79.6% 。54例复发患者中,紫杉醇联合卡铂/顺铂化疗24例患者,另有12例采用顺铂加其他药物化疗肿瘤进展而改用紫衫醇联合顺铂/卡铂化疗;顺铂加其他药物化疗30例患者,另有6 例因紫杉醇联合顺铂/卡铂化疗无效而改为顺铂加其他药物化疗。紫杉醇联合卡铂/顺铂化疗的24例患者中,有效率(CR+PR)58.33%(14/24),其中照射野内复发化疗的有效率40%(4/10),低于照射野外复发患者化疗的有效率66.7%(10/14);顺铂加其他药物化疗的患者30例,有效率13.33%(4/30),其中15例照射野内复发者有效率6.67%(1/15),15例照射野外复发者有效率20%(3/15)。 紫杉醇联合铂类化疗的有效率高于顺铂加其他药物化疗的有效率(χ2=14.351,P<0.001)。 在紫杉醇联合化疗患者中,虽然照射野外复发灶的有效率为66.7% ,高于照射野内复发灶40% 的有效率,但差异不显著(χ2=1.67,P=0.20);顺铂加其他药物化疗方案的患者,照射野内复发灶的有效率6.67% ,照射野外复发灶的有效率为20% ,差异性不显著(χ2=1.17,P=0.30)。 两组化疗患者Ⅲ~Ⅳ度骨随抑制无显著性差异(χ2=0.069,P=0.80)。 54例患者生存时间3~54个月,平均生存(11.96± 1.246)个月,中位生存时间10个月。总的1、2 年生存率分别为48.9% 、26.33% 。单因素分析发现,肿瘤复发部位(照射野内、外复发)、肿瘤分级、化疗方案(紫杉醇联合铂类方案vs 顺铂加其他药物方案)、化疗中SCC 是否下降、化疗是否有效与生存有关(P<0.05),而多因素分析发现仅紫杉醇联合铂类、化疗有效是独立的预后因素。结论:本回顾性研究发现,紫杉醇联合铂类较其他铂类为主的联合化疗方案治疗宫颈癌复发患者有效。但需要大样本多中心的随机对照研究。

     

    Abstract: Objective:To discuss effectual chemotherapeutic regimens of recurrent carcinoma of the cervix. Methods:A retrospective analysis and study of the data of 54patients with recurrent cervical cancer, who were treated with combined therapy of paclitaxel plus carboplatin/cisplatin with other drugs in the Cancer Hospital of Peking Union Medical College and Chinese Academy of Medical Sciences during the period from1998to 2007, were conducted. Results: Recurrence after rad-ical surgery occurred in 11of the 54patients, and post-radiotherapeutic relapse occurred in the other 43patients (including those undergoing postoperative radiotherapy). In 24of the 54patients, relapse occurred at the irradiated sites and in the other 30patients (including those without radiotherapy after undergoing initial surgery), the recurrent cancer occurred out-side of irradiated sites. The mean age of the patients at diagnosis of the recurrence was 46.7 ± 1.442 (range, 27-70) years, with a median of45. The mean recurrence time after initial surgery was 13.80± 2.34(range, 3-96) months, and the median time of the relapse was 8 months. The serum SCCAg rose in 43of the 54recurrent patients, with a ratio of 79.6%. Of the 54patients, 24were treated with paclitaxel plus cisplatin (PT) or carboplatin (PC), and12also received the same regimens because of progression of the disease after undergoing other cisplatin-based combined chemotherapy. Thirty of the 54pa-tients were treated with combined chemotherapy of cisplatin plus other drugs. In addition, 6 patients received PT or PC regi -men because of ineffective cisplatin-based chemotherapeutics. The overall response rate was 58.33% (14/24), including CR+PR, in the 24patients receiving PT or PC regimen, whereas the response rate was 40% (4/10) in the patients with recurrence at the irradiated sites, which was lower than that of 66.7% (10/14) in the patients with relapse outside of the irradi -ated sites. The response rate of 30patients receiving other cisplatin-based chemotherapeutics was 13.33% (4/30), where -as the response rate was 6.67% (1/15) in 15patients with recurrent disease at the irradiated sites and 20% (3/15) in anoth-er 15with the relapse outside the irradiated sites. The effectual rate was higher in the patients with PT or PC regimens than in those with cisplatin-based regimens ( 58.33% vs.13.33%,χ2 value = 14.351 , P<0.001 ). There were no significant differ -ences in comparison of the response rates between the patients with the relapses inside and outside the irradiated sites (66.7% vs.40%,χ2 value = 1.67, P=0.20, i.e. > 0.05). The median survival time of the 54patients was 10months and the mean survival time was11.96± 1.246 months (range, 3 ~ 54months). The 1- and 2-year overall survival rates were 48.9% and 26.33%, respectively. It was shown by univariate analysis that recurrent sites (inside or outside the irradiated field), tumor grading, chemotherapeutic regimens (PT or PC vs. other cisplatin-based combined therapy), decline of SCCAg during or after the chemotherapy and effectiveness of the chemotherapy significantly affect the survival rates (P <0.05), while only PT or PC chemotherapy and efficacy of chemotherapy were revealed by the multivariate analysis as the independent prog-nostic factors.Conclusion : According to our retrospective study, the combination therapy of paclitaxel with cisplatin or carbo -platin is more effective than the combined regimens of other cisplatin-based drugs in recurrent carcinomas of the cervix. However, further randomized studies are needed.
