Cervical cancer is the second most common cancer among women and is the most frequent cause of death from gynaecological cancers worldwide. Standard surgical management for selected early-stage cervical cancer is radical hysterectomy. Traditionally, radical hysterectomy has been carried out via the abdominal route and this remains the gold standard surgical management of early cervical cancer. In recent years, advances in minimal access surgery have made it possible to perform radical hysterectomy with the use of laparoscopy with the aim of reducing the surgical morbidity and promoting a faster recovery.
To compare the effectiveness and safety of laparoscopically assisted radical vaginal hysterectomy (LARVH) and radical abdominal hysterectomy (RAH) in women with early-stage (1 to 2A) cervical cancer.
We searched the Cochrane Gynaecological Cancer Group Trials Register, and Cochrane Register of Controlled Trials (CENTRAL) Issue 7, 2013, MEDLINE, and EMBASE up to July 2013. We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.
Randomised controlled trials (RCTs) that compared laparoscopically assisted radical hysterectomy and radical abdominal hysterectomy, in adult women diagnosed with early (stage 1 to 2A) cervical cancer.
Two review authors independently abstracted data and assessed risk of bias.
We found one RCT, which included 13 women, that met our inclusion criteria and this trial reported data on LARVH versus RAH.Women who underwent LARVH for treatment of early-stage cervical cancer appeared to have less blood loss compared with those who underwent RAH. The trial reported a borderline significant difference between the two types of surgery (median blood loss 400 mL (interquartile range (IQR): 325 to 1050) and 1000 mL (IQR: 800 to 1025) for LARVH and RAH, respectively, P value = 0.05). RAH was associated with significantly shorter operation time compared with LARVH (median: 180 minutes with LARVH versus 138 minutes with RAH, P value = 0.05).There was no statistically significant difference in the risk of perioperative complications in women who underwent LARVH and RAH. The trial reported two (29%) and four (57%) cases of intraoperative and postoperative complications, respectively, in the LARVH group and no (0%) reported cases of intraoperative complications and five (83%) cases of postoperative complications in the RAH group. There were no reported cases of severe perioperative complications.Bladder and bowel dysfunction of either a transient or chronic nature remain major morbidities after radical hysterectomy, and the one included study showed that there may be significantly less after LARVH.
AUTHORS' CONCLUSIONS: The included trial lacked statistical power due to the small number of women in each group and the low number of observed events. Therefore, the absence of reliable evidence, regarding the effectiveness and safety of the two surgical techniques for the management of early-stage cervical cancer, precludes any definitive guidance or recommendations for clinical practice. The trial did not report data on long-term outcomes, but was at moderate risk of bias due to very low numbers of included women.
宫颈癌是女性中第二常见的癌症,也是全球妇科癌症最常见的死亡原因。对于部分早期宫颈癌,标准的手术治疗方法是根治性子宫切除术。传统上,根治性子宫切除术是通过腹部途径进行的,这仍然是早期宫颈癌手术治疗的金标准。近年来,微创外科手术的进展使得利用腹腔镜进行根治性子宫切除术成为可能,目的是降低手术发病率并促进更快康复。
比较腹腔镜辅助根治性阴道子宫切除术(LARVH)与根治性腹部子宫切除术(RAH)治疗早期(1至2A期)宫颈癌女性的有效性和安全性。
我们检索了Cochrane妇科癌症组试验注册库、截至2013年第7期的Cochrane对照试验注册库(CENTRAL)、MEDLINE以及截至2013年7月的EMBASE。我们还检索了临床试验注册库、科学会议摘要、纳入研究的参考文献列表并联系了该领域的专家。
比较腹腔镜辅助根治性子宫切除术与根治性腹部子宫切除术的随机对照试验(RCT),研究对象为诊断为早期(1至2A期)宫颈癌的成年女性。
两位综述作者独立提取数据并评估偏倚风险。
我们发现一项符合纳入标准的RCT,该研究纳入了13名女性,报告了LARVH与RAH对比的数据。与接受RAH的女性相比,接受LARVH治疗早期宫颈癌的女性似乎失血更少。该试验报告两种手术方式之间存在临界显著差异(LARVH和RAH的中位失血量分别为400 mL(四分位间距(IQR):325至1050)和1000 mL(IQR:800至1025),P值 = 0.05)。与LARVH相比,RAH的手术时间明显更短(中位时间:LARVH为180分钟,RAH为138分钟,P值 = 0.05)。接受LARVH和RAH的女性围手术期并发症风险无统计学显著差异。该试验报告LARVH组分别有2例(29%)和4例(57%)术中及术后并发症,RAH组未报告术中并发症(0%),有5例(83%)术后并发症。未报告严重围手术期并发症病例。根治性子宫切除术后,无论是短暂性还是慢性的膀胱和肠道功能障碍仍然是主要的发病情况,纳入的一项研究表明LARVH术后可能明显更少。
由于每组女性数量少且观察到的事件数量少,纳入的试验缺乏统计学效力。因此,缺乏关于这两种手术技术治疗早期宫颈癌有效性和安全性的可靠证据,无法为临床实践提供任何明确的指导或建议。该试验未报告长期结局数据,但由于纳入女性数量极少,存在中度偏倚风险。
