OBJECTIVE: Clinical benefit of surgical staging in locally advanced cervical cancer has not yet been proved. The goal of this study was to analyze the prognostic and therapeutic value of laparoscopic para-aortic lymphadenectomy with selective excision of suspicious pelvic nodes in patients with locally advanced cervical cancer. METHODS: This is a retrospective study including 109 women treated in a single institution from 2000 to 2009. The International Federation of Gynecology and Obstetrics stage was IB2 in 12 women, IIB in 58 women, and IIIB in 39 women. None had suspicious para-aortic nodes by presurgical imaging evaluation. All patients underwent extraperitoneal para-aortic laparoscopic lymphadenectomy with selective excision of enlarged pelvic nodes and received pelvic radiotherapy with concomitant chemotherapy. Extended lumboaortic radiation therapy was added to patients with metastatic para-aortic nodes. The mean ± SD follow-up time was 43.1 ± 33.7 months. RESULTS: Metastatic lymph nodes were identified in 23 (21.1%) of 109 patients in the para-aortic area and in 24 (53.3%) of 45 patients who underwent selective excision of pelvic nodes. Patients with nodal metastases had increased risk of mortality than those with negative nodes independently of the location (pelvic and/or para-aortic) of the metastases (hazard ratio, 4.07; 95% confidence interval, 1.36-12.16 for patients with pelvic metastases [P = 0.012]; and 3.73; 95% confidence interval, 1.38-10.09 for patients with para-aortic metastases [P = 0.010]). In the subset of women with para-aortic metastases treated by extended lumboaortic radiation therapy, neither the number of lymph nodes removed nor the number of positive nodes were associated with survival (P = 0.556 and P = 0.195, respectively). CONCLUSION: Para-aortic and pelvic lymphadenectomy provides valuable information about mortality risk in patients with locally advanced cervical cancer.
目的:手术分期在局部晚期宫颈癌中的临床获益尚未得到证实。本研究的目的是分析腹腔镜腹主动脉旁淋巴结清扫术联合选择性切除可疑盆腔淋巴结在局部晚期宫颈癌患者中的预后和治疗价值。
方法:这是一项回顾性研究,纳入了 2000 年至 2009 年在一家机构接受治疗的 109 名女性患者。国际妇产科联合会(FIGO)分期为 IB2 期 12 例,IIB 期 58 例,IIIB 期 39 例。所有患者术前影像学检查均未发现可疑腹主动脉旁淋巴结。所有患者均行腹膜外腹腔镜腹主动脉旁淋巴结清扫术,选择性切除肿大的盆腔淋巴结,并接受盆腔放疗联合化疗。转移性腹主动脉旁淋巴结患者加行扩展腰主动脉放疗。平均随访时间为 43.1±33.7 个月。
结果:109 例患者中有 23 例(21.1%)在腹主动脉区发现转移性淋巴结,45 例选择性切除盆腔淋巴结的患者中有 24 例(53.3%)发现转移性淋巴结。有淋巴结转移的患者死亡风险高于无淋巴结转移的患者,无论转移部位(盆腔和/或腹主动脉)如何(危险比,4.07;95%置信区间,1.36-12.16,用于有盆腔转移的患者[P=0.012];和 3.73;95%置信区间,1.38-10.09,用于有腹主动脉转移的患者[P=0.010])。在接受扩展腰主动脉放疗的腹主动脉转移患者亚组中,切除的淋巴结数量和阳性淋巴结数量均与生存无关(P=0.556 和 P=0.195)。
结论:腹主动脉和盆腔淋巴结清扫术可提供局部晚期宫颈癌患者死亡风险的有价值信息。
