ⅠB期和ⅡA期宫颈癌患者的预后因素分析

目的 探讨影响ⅠB期和ⅡA期宫颈癌预后的高危因素。方法 1992年12月-2001年12月手术治疗的111例宫颈浸润癌,中位年龄40岁。按FIGO(1994)分期标准,ⅠB期80例(ⅠB1期和ⅠB2期各40例),ⅡA期31例。鳞癌93例(8318％),腺癌17例(15.3％),小细胞癌1例。111例患者均采用广泛性子宫切除加以撕剥式为主的盆腔淋巴清扫术,术前辅助放疗74例(66.7％),术后辅助治疗24例(21.6％)。生存率统计采用Kaplan-Meier方法,预后相关因素分析采用Cox模型和x^2检验。结果 全组患者5年生存率为85.9％,其中ⅠB1期为89.1％,ⅠB2期为90.7％,HA期为78.4％。经单因素分析显示,肿瘤大小(HR=1.479,P=0.152)、肿瘤局部类型(HR=1.440,P=0.264)、临床分期(HR=1.380,P=0.354)、术前和(或)术后辅助治疗(HR=1.210,P=0.450)、淋巴结转移(HR=1.432,P=0.540)、颈管受侵(HR=2.244,P=0.036)、深肌层浸润(HR=3.295,P=0.06)和多个性伴侣 合并妊娠(HR=10.172,P=0.000)与早期宫颈癌预后有关。经多因素分析显示,宫颈深肌层浸润和多个性伴侣 合并妊娠是影响预后的重要因素。结论 宫颈深肌层浸润和多个性伴侣 合并妊娠与早期宫颈癌预后密切相关,对具有高危因素的ⅠB期和ⅡA期宫颈癌患者应加强术前和(或)术后的辅助治疗。

Prognostic factors of stage IB and IIA carcinoma of the cervix treated by surgery

OBJECTIVE: To evaluate prognostic factors in patients with stage IB-IIA of cervical carcinoma treated by surgery. METHODS: Between December 1992 and December 2001, 111 patients with stage IB-IIA cervical cancer surgically treated were analyzed. Median age 40 years. According to 1994 FIGO Staging System: IB 80 (IB1 40, IB2 40) and IIA 31. There were 93 cases of squamous cell carcinoma (83.5%), 17 cases of adenocarcinoma (15.3%) and one case of small cell carcinoma. All patients were treated by radical hysterectomy and pelvic lymphadenectomy, 74 patients had preoperative adjuvant radiotherapy, 24 patients had postoperative adjuvant treatment. Kaplan-Meier method was used to evaluate the survival, the related prognostic factors were assessed by Cox regression and chi(2) test. RESULTS: The overall 5-year survival rate was 85.9%, being 89.1%, 90.7% and 78.4% for stage IB1, IB2 and IIA, respectively. Univariate analysis showed that tumor size (hazards ratio HR] = 1.479, P = 0.152), tumor type (HR = 1.440, P = 0.264), clinical stage (HR = 1.380, P = 0.354), adjuvant treatment (HR = 1.210, P = 0.450), lymph node metastasis (HR = 1.432, P = 0.540), endocervical involvement (HR = 2.244, P = 0.036), depth of myometrial invasion (HR = 3.295, P = 0.06) and multiple sexual partners during pregnancy (HR = 10.172, P = 0.000) were of prognostic significance. The latter two were the most important factors indicative of poor prognosis. CONCLUSION: The depth of myometrial invasion and multi-partners combined with pregnancy are closely related to the prognosis while the pre- and/or postoperative adjuvant therapy should be considered for stage IB-IIA cervical cancer with deep myometrial invasion and in pregnant patients with multiple sexual partners.
