AbstractObjective: Investigate the relationship between surgical proficiency and oncological outcomes of minimally invasive surgery (MIS) in the treatment of early-stage cervical cancer. Methods: This retrospective study included patients with cervical cancer stage IB1, IB2 who were treated with minimally invasive radical hysterectomy from January 2010 to Dec 2020. Patients were divided into two groups based on the year of surgery: phase 1 (from January 2010 to December 2015) and phase 2 (from January 2016 to December 2020). Oncologic outcomes were compared between the groups. Results: In total, 142 patients were included in the final analysis. 73 and 69 patients underwent surgery in phase 1 (51.4%) and phase 2 (48.6%), respectively. Twelve recurrences (12/142, 8.5%) were observed in the entire cohort: ten (13.7%) in phase 1 and two (2.9%) in phase 2. The recurrence rate was significantly higher in phase 1 (p = 0.021). And the phase 1 group showed significantly shorter disease-free survival than the phase 2 group (p = 0.049). In the multivariate analysis, surgical proficiency, represented by the phase of operation, was the only significant predictor of disease-free survival (HR = 0.244, p = 0.042). Conclusions: Surgical proficiency in MIS is a significant factor associated with the outcomes in early-stage cervical cancer. More favorable outcomes can be obtained after operating on a certain number of MIS cases.© The author(s).
