[Comparative analysis of the prognosis of patients with locally advanced cervical cancer undergoing laparoscopic or abdominal surgery].

To compare the prognosis of patients with cervical cancer in stage Ⅰb2-Ⅱa2 undergoing laparoscopic radical hysterectomy or abdominal radical hysterectomy. 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. (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 >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 (>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 (=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 (=0.405, =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 <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 <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 (<0.05). 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.
