Objective: To compare the prognosis of patients with cervical cancer in stage Ⅰb2-Ⅱa2 undergoing laparoscopic radical hysterectomy or abdominal radical hysterectomy. Methods: From January 1, 2009 to December 31, 2018, patients with stage Ⅰb2-Ⅱa2 who underwent laparoscopic or abdominal radical hysterectomy (laparoscopic group and abdominal group) in Peking University People's Hospital were collected. The clinicopathological data were retrospectively analyzed. There were 237 cases in this study, including 115 cases in laparoscopic group and 122 cases in abdominal group. The clinicopathological characteristics, surgery-related complications, recurrence and death were analyzed between the two groups. The related factors of recurrence and death were also analyzed.During laparoscopic surgery, the pressure of the carbon dioxide pneumoperitoneum were controlled, to try avoid the tumor tissue in the vagina from being exposed to the abdominal cavity when taking out the uterine specimen through the vagina, and fully flushed the abdominal cavity with sterile water after the specimen was taken out. Results: (1) Clinicopathological characteristics: there was no significant differences between the two groups among age, pathological type, pathological grade, clinical stage, depth of interstitial infiltration, lymph node metastasis,parametrial infiltration, vaginal stump infiltration, lymph-vascular space invasion (LVSI), neoadjuvant chemotherapy, and postoperative adjuvant treatments (all P>0.05). (2) Surgery-related complications: the incidence of surgery-related complications in the laparoscopic group and the abdominal group were 32.2% (37/115) and 25.4% (31/122), respectively. There was no statistically significant difference between the two groups (P>0.05). (3) Recurrence and death: during the follow-up period, the recurrence rates of the laparoscopic group and the abdominal group were respectively 15.7% (18/115) and 12.3% (15/122). There was no statistically significant difference between the two groups (P=0.456). The 5-year overall survival rates of the laparoscopic group and the open group were 86.8% and 87.8%, and the 5-year tumor-free survival rates were 81.7% and 84.6%, respectively. There were no statistically significant differences between the two groups (P=0.405, P=0.429). (4) Analysis of related factors of recurrence and death: univariate analysis showed that neoadjuvant chemotherapy, lymph node metastasis, vaginal stump infiltration, LVSI and interstitial infiltration depth were risk factors for postoperative recurrence of cervical cancer patients (all P<0.05); neoadjuvant chemotherapy, lymph node metastasis, parametrial infiltration, vaginal stump infiltration, LVSI and interstitial infiltration depth were risk factors for postoperative death in patients with cervical cancer (all P<0.05). Multivariate analysis showed that neoadjuvant chemotherapy and lymph node metastasis were independent risk factors for postoperative recurrence and death of cervical cancer patients (P<0.05). Conclusion: There is no significant difference in the prognosis of patients with cervical cancer in stage Ⅰb2-Ⅱa2 undergoing laparoscopic radical hysterectomy with non-touch operative technique and abdominal radical hysterectomy.
目的： 比较Ⅰb2~Ⅱa2期子宫颈癌患者行腹腔镜与开腹子宫广泛性切除术的预后差异。 方法： 收集2009年1月1日—2018年12月31日北京大学人民医院10年间收治的Ⅰb2~Ⅱa2期、行腹腔镜或开腹子宫广泛性切除术患者（分别为腹腔镜组、开腹组）的临床病理资料进行回顾性分析，共有237例纳入本研究，其中腹腔镜组115例、开腹组122例，比较两组患者的临床病理特征、手术相关并发症、复发及死亡情况，并对影响复发及死亡的相关因素进行分析。本院腹腔镜手术采取控制CO2气腹压力，经阴道取出子宫标本时尽量避免阴道内肿瘤组织暴露于腹腔中，取出标本后用灭菌注射用水充分冲洗腹腔的无瘤措施。 结果： （1）临床病理特征：腹腔镜组、开腹组患者的年龄、病理类型、病理分级、临床分期、间质浸润深度、淋巴结转移、宫旁浸润、阴道残端浸润、淋巴脉管间隙浸润（LVSI）、新辅助化疗、术后辅助治疗分别比较，差异均无统计学意义（P>0.05）。（2）手术相关并发症：腹腔镜组、开腹组的手术相关并发症发生率分别为32.2%（37/115）、25.4%（31/122），两组比较，差异无统计学意义（P>0.05）。（3）复发及死亡情况：随访期内，腹腔镜组、开腹组的复发率分别为15.7%（18/115）、12.3%（15/122），两组比较，差异无统计学意义（P=0.456）。腹腔镜组、开腹组的5年总生存率分别为86.8%、87.8%，5年无瘤生存率分别为81.7%、84.6%，两组分别比较，差异均无统计学意义（P=0.405，P=0.429）。（4）影响复发及死亡的相关因素分析：单因素分析显示，新辅助化疗、淋巴结转移、阴道残端浸润、LVSI、间质浸润是影响子宫颈癌患者术后复发的危险因素（P<0.05）；新辅助化疗、淋巴结转移、宫旁浸润、阴道残端浸润、LVSI、间质浸润是影响子宫颈癌患者术后死亡的危险因素（P<0.05）。多因素分析显示，新辅助化疗、淋巴结转移是影响子宫颈癌患者术后复发和死亡的独立危险因素（P<0.05）。 结论： 对于行子宫广泛性切除术的Ⅰb2~Ⅱa2期子宫颈癌患者，经采用无瘤措施的腹腔镜手术与开腹手术的预后无显著差异。.
