To compare the surgical and oncologic outcomes between open abdomen radical hysterectomy (ARH) and laparoscopic radical hysterectomy (LRH) for cervical cancer. Retrospective observational study with propensity score matching was used to ensure balanced groups for ARH and LRH. One-hundred-and-ninety-eight women with cervical cancer, 99 treated using ARH and 99 using LRH, between January 2012 and December 2014. Outcomes included disease-free survival (DFS), overall survival (OS), intra-operative factors, post-operator recovery, urinary retention, and adverse events. Moreover, the inverse probability of the treatment weighting (IPTW) method was also used. Compared with ARH, LRH was associated with a lower volume of blood loss ( < 0.001) and transfusion rate ( < 0.001), with a broader resection of the parametrium ( < 0.001). Post-operatively, the time to first flatus was shorter for LRH than ARH ( < 0.001) but the rate of urinary retention was higher for LRH (22.2%) than ARH (8.1%; = 0.009). DFS and OS were similar between groups. By IPTW, laparoscopy was also not associated with poorer survival in terms of DFS (HR 1.52, CI 0.799-2.891, = 0.202) or OS (HR 0.942, HR 0.425-2.09, = 0.883). Compared with ARH, LRH provided better intra-operative and post-operative outcomes, with no significant difference in oncologic outcomes and survival. Urinary retention remains a clinical issue to improve with LRH. The technology of LRH has been improved in China to address the inconsistent results of oncologic outcomes in previous studies. Whether these improvements could be effective needs to be investigated in the future.
比较开放性腹部根治性子宫切除术(ARH)和腹腔镜根治性子宫切除术(LRH)治疗宫颈癌的手术及肿瘤学结局。采用倾向评分匹配的回顾性观察性研究,以确保ARH组和LRH组具有均衡性。2012年1月至2014年12月期间,198例宫颈癌女性患者,99例接受ARH治疗,99例接受LRH治疗。结局指标包括无病生存期(DFS)、总生存期(OS)、术中因素、术后恢复情况、尿潴留及不良事件。此外,还采用了治疗权重反概率(IPTW)方法。与ARH相比,LRH术中失血量更少(<0.001)、输血率更低(<0.001),宫旁组织切除范围更广(<0.001)。术后,LRH组首次排气时间比ARH组短(<0.001),但LRH组尿潴留发生率(22.2%)高于ARH组(8.1%;P = 0.009)。两组间DFS和OS相似。通过IPTW分析,就DFS(风险比1.52,可信区间0.799 - 2.891,P = 0.202)或OS(风险比0.942,可信区间0.425 - 2.09,P = 0.883)而言,腹腔镜手术也未显示出生存率较差。与ARH相比,LRH在术中及术后结局方面表现更好,在肿瘤学结局和生存率方面无显著差异。尿潴留仍是LRH需要改善的临床问题。中国已改进LRH技术,以解决既往研究中肿瘤学结局不一致的问题。这些改进是否有效有待未来进一步研究。
