Efficacy and safety outcomes of robotic radical hysterectomy in Chinese older women with cervical cancer compared with laparoscopic radical hysterectomy

摘要

BACKGROUND: Recently, as a complex integrating a number of modern high-tech means, robotic surgery system is a well-deserved revolutionary tool in globally minimally invasive surgical field. For the first time in China, the objective of this study was to evaluate the efficacy and safety outcomes of robotic radical hysterectomy (RRH) in Chinese older women with cervical cancer compared with laparoscopic radical hysterectomy (LRH). METHODS: In this prospective, randomized and double-blinded study, 60 Chinese older women with cervical cancer were evenly divided to accept the RRH or LRH. Follow-up period lasted for 24 months. RESULTS: Median age for the entire cohort was 65 (range: 61-69) years. There was no difference in International Federation of Gynecology and Obstetrics (FIGO) stages and cell types between two groups (p > 0.05 for all). Uterine size, tumor size, vaginal length and numbers of left and right pelvic lymph nodes did not differ between two groups (p > 0.05 for all). No difference was observed in numbers of left and right lymph node metastasis (p > 0.05 for all). All patients had negative margins without conversion to laparotomy. There were significantly less postoperative complications in the RRH group than in the LRH group (p < 0.05). Shorter indwelling time of bladder and drain catheters was observed in the RRH group than in the LRH group (p < 0.05 for all). Length of postoperative hospital stay in the RRH group was significantly shorter compared with that in the LRH group (p < 0.05). Patients in two groups similarly experienced the recurrence and death (p > 0.05 for all). CONCLUSIONS: This study demonstrated that RRH provided additional benefits for Chinese older women with cervical cancer because of less complications and faster recovery compared with LRH. Meanwhile, this study supported an equivalence of surgical qualities and survival outcomes of RRH to LRH. Robotics-assisted surgical method is effective, safe and feasible for Chinese older women with cervical cancer.
