Objective: To analyze the effect of surgical experience with laparoscopic radical hysterectomy (LRH) on oncological outcome in cervical cancer patients. Methods: We retrospectively compared the oncological outcomes of 1469 patients with stage IB1 cervical cancer receiving LRH from 2004 to 2016. The surgical volume for each surgeon was defined as low (fewer than 50 surgeries), mid (51-100 surgeries), and high (100 surgeries or more). Kaplan-Meier curves and the Cox proportional hazards model were used to estimate the effect of surgical experience on the oncological outcomes of patients. Results:A total of 1405 cases were included in this study. The average operative times of the low-volume (n = 427), mid-volume (n = 396) and high-volume (n=582) groups were 270, 260 and 227 minutes, respectively (P < 0·001), and mean blood loss was 218 ml, 197 ml and 179 ml, respectively (P = 0·004). The 5-year OS of the low-volume, mid-volume and high-volume groups was 96·1%, 93·1% and 92·5%, with 5-year DFS rates of 92·0%, 87·5% and 87·6%, respectively. There was no significant difference among the three groups. However, surgery volume was not an independent risk factor for shorter OS or DFS after controlling for case mix, nor was surgeons’ experience after 1:1 PSM (Propensity score matching) between each two of the three groups. Conclusion: The results showed that surgeons’ surgical volume did not affect the oncological outcome of LRH but that operative time and blood loss were significantly improved with a higher surgical volume.

Objective Explore the difference of oncology outcome of laparotomy and laparoscopy in the new FIGO2018 stage of early cervical squamous cell carcinoma without any high risk pathological factors. Methods The 5-years OS and DFS of cervical squamous cell carcinoma undergoing laparotomy and laparoscopy from 2004 to 2018 were compared by the total study population and propensity score from China. Result There was no difference in 5-year OS between laparotomy (2,478 cases) and laparoscopy (1,504 cases), but the 5-year DFS of laparotomy was higher (92.2 %vs. 90.4%, P=0.022). Cox analysis showed that laparoscopy was not an independent risk factor for the death of cervical squamous cell carcinoma (OS: P=0.598), but it was an independent risk factor for the recurrence/death (HR = 1.468,95% CI 1.131 ~ 1.906, P=0.004). There was no difference in 5-year OS between laparotomy (2,391 cases) and laparoscopy (1,495 cases) after 1:2 PSM, but the 5-year DFS of laparotomy was higher (92.7% vs. 90.8%, P = 0.006), Cox analysis showed that laparoscopy was not an independent risk factor for the death of cervical squamous cell carcinoma (OS: P=0.521), but it was an independent risk factor for the recurrence/death (HR=1.512, 95%CI 1.151~1.971, P=0.002). Conclusion There is no difference in 5-year OS between these groups for early cervical squamous cell carcinoma in new stage of FIGO2018 without any high-risk pathological factors, the 5-year DFS of laparotomy is higher than that of laparoscopy group, and laparoscopy is an independent risk factor for recurrence/death, so laparoscopy has a higher risk of recurrence.

Objective To compare long-term survival outcomes between laparoscopic radical hysterectomy (LRH) and open radical hysterectomy (ORH) in early-stage cervical adenocarcinoma under the new FIGO 2018 staging guideline. Design Retrospective study Setting and population Early-stage cervical adenocarcinoma received LRH and ORH; 47 Chinese hospitals. Methods We matched patients with early-stage cervical adenocarcinoma in the new FIGO 2018 staging guideline with known risk factors for recurrence who underwent ORH and LRH. Main Outcome Measures 5-year overall survival and 5-year disease-free survival rates Results In total, 549 patients were enrolled in our study, including 235 patients in LRH group and 314 in ORH group. After matching some factors that may affect the prognosis, each group had 223 patients. There was no difference in DFS between LRH and ORH in risk-adjusted analysis (HR1.258, 95% CI: 0.507-3.125, P=0.621). There was no difference in OS between LRH and ORH in risk-adjusted analysis (HR1.961, 95% CI: 0.536-7.183, P=0.309). LRH resulted in significantly lower estimated blood loss (361.2 versus 165.3 ml, P < 0.001) and shorter postoperative anal exhaust time (2.8 versus 2.5 days, P = 0.003) . Intraoperative complication ( 2.7% versus 5.8%,P=0.101) and postoperative complication ( 5.8% versus 6.3%, P=0.843) rates were similar in the two groups. Conclusions LRH has comparable survival outcomes with ORH and was associated with earlier recovery in early-stage adenocarcinoma of the uterine cervix. LRH may be an appropriate option for early-stage cervical adenocarcinoma compared with ORH.

Objective: Compare the outcomes associated with laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) for cervical cancer. Design: Retrospective, multicenter observational analysis Setting: Select patients of LRH and ARH from cervical cancer database and compare their outcomes. Population: Patients with stage IA1 (Lymphovascular space invasion [LVSI]-positive) and stage IIA2 cervical cancer (N=6804) were enrolled, of whom 3003 underwent laparoscopy (LRH group), and 3801 underwent laparotomy (ARH group). Methods: Kaplan-Meier survival analysis,propensity score matching (PSM) and Cox regression. Main Outcome Measures: Five-year overall survival (OS) and 5-year disease-free survival (DFS) Results: Before PSM, there was no difference in outcomes between the groups (5-year OS: LRH 89.2% vs. ARH 90.6%, P=0.903.; 5-year DFS: LRH 84.5% vs. ARH 87.1%, P=0.155). Surgical approach did not affect 5-year OS; however, it did affect 5-year DFS (hazard ratio [HR]=0.827, 95% confidence interval [CI]: 0.711-0.962, P=0.014). After PSM, there was no difference in 5-year OS between the LRH (N=1828) and ARH (N=1828) groups (91.0% vs. 93.1%, P=0.220); but there was a significant difference in 5-year DFS between the LRG and ARH groups (86.2% vs. 90.6%, P=0.002). Cox regression revealed that the surgical approach did not affect 5-year OS; however, it did affect 5-year DFS (HR=0.701, 95% CI: 0.563-0.874, P=0.002). Conclusions: For IA1 (LVSI-positive) and IIA1 cervical cancers, the recurrence rate following laparoscopic surgery was higher than that following open surgery, regardless of the surgeon’s experience.
