RESUMO
AIM: Lately, the safety of minimally invasive surgery (MIS) in the treatment of cervical cancer (CC) has been questioned. This study aimed to evaluate the risk of recurrence and survival after a nationwide adoption of robotic MIS for the treatment of early-stage CC in Denmark. METHODS: Population-based data on all Danish women with early-stage CC, who underwent radical hysterectomy January 1st 2005-June 30th 2017 were retrieved from the Danish Gynecologic Cancer Database and enriched with follow-up data on recurrence, death and cause of death. The cohort was divided into two groups according to the year of robotic MIS introduction at each cancer centre. Chi-squared or Fischer test, the Kaplan Meier method and multivariate Cox regression were used for comparison between groups. RESULTS: One thousand one hundred twenty-five patients with CC were included; 530 underwent surgery before (group 1) and 595 underwent surgery after (group 2) the introduction of robotic MIS. The 5-year rate of recurrence was low: 8.2% and 6.3% (p = 0.55) in group 1 and 2, respectively. In adjusted analyses, this corresponded to a five-year disease-free survival, hazard ratio (HR) 1.23 [95% confidence interval (CI) 0.79-1.93]. No difference in site of recurrence (P = 0.19) was observed. The cumulative cancer-specific survival was 94.1% and 95.9% (P = 0.10) in group 1 and 2, respectively, corresponding to a HR 0.60 [95% CI 0.32-1.11] in adjusted analyses. CONCLUSION: In this population-based cohort study, the Danish nationwide adoption of robotic MIS for early-stage CC was not associated with increased risk of recurrence or reduction in survival outcomes.

INTRODUCTION: Robot-assisted surgery has become more widespread in gynecological oncology. The purpose of this systematic review is to present current knowledge on robot-assisted surgery, and to clarify and discuss controversies that have arisen alongside the development and deployment. MATERIAL AND METHODS: A database search in PubMed and EMBASE was performed up until 4 March 2016. The search strategy was developed in collaboration with an information specialist, and by application of the PRISMA guidelines. Human participants and English language were the only restrictive filters applied. Selection was performed by screening of titles and abstracts, and by full text scrutiny. From 2001 to 2016, a total of 76 references were included. RESULTS: Robot-assisted surgery in gynecological oncology has increased, and current knowledge supports that the oncological safety is similar, compared with previous surgical methods. Controversies arise because current knowledge does not clearly document the benefit of robot-assisted surgery, on perioperative outcome compared with the increased costs of the acquisition and application. CONCLUSIONS: The rapid development in robot-assisted surgery calls for long-term detailed prospective cohorts or randomized controlled trials. The costs associated with acquisition, application, and maintenance have an unfavorable impact on cost-benefit evaluations, especially when compared with laparoscopy. Future developments in robot-assisted surgery will hopefully lead to competition in the market, which will decrease costs.
