Observational BGOG Study of the Results of Robot-assisted Laparoscopy in 166 Patients with FIGO 2009 Stage IA1-IB1 Cervical Cancer.

STUDY OBJECTIVE: Two recent studies (the Laparoscopic Approach to Cervical Cancer [LACC] trial and a cohort study based on the National Cancer Database) raise the question of whether minimally invasive surgery (conventional and robot-assisted laparoscopy) is inferior to open abdominal surgery in early-stage cervical cancer. In the laparotomy group of the LACC trial, the low rates of recurrence and death are notable. The present study wants to elucidate the current situation of patients with early-stage cervical cancer treated with robot-assisted laparoscopy in hospitals of the Belgium and Luxembourg Gynaecological Oncology Group (BGOG). DESIGN: This is a prospective follow-up study. SETTING: The combined data obtained from different BGOG hospitals were analyzed regarding patients similar to those included in the LACC trial in terms of cervical cancer recurrence and survival. PATIENTS: We included patients with stage IA1, IA2, or IB1 cervical cancer with a histologic subtype of squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma. INTERVENTIONS: All patients were treated with robot-assisted laparoscopy. MEASUREMENTS AND MAIN RESULTS: The outcomes were disease-free and overall survival at 3 and 5 years after surgery. A total of 270 patients were included, and 166 were found suitable for analysis. The median age was 45 years. Most patients had International Federation of Gynecology and Obstetrics stage IB1 cervical cancer (84.9%) and squamous cell carcinoma as the histologic subtype (71.7%). The median follow-up time was 44 months, with a range of between 1 and 131 months. Twenty-one recurrences and 12 deaths were noted. Of the deaths, 8 were related to cervical cancer. Disease-free survival was 86% at 3 years (95% confidence interval [CI], 78.52-90.80) and 85% at 5 years (95% CI, 77.03-89.95). Overall survival was 96% at 3 years (95% CI, 90.11-98.22) and 91% at 5 years (95% CI, 82.54 95.17). CONCLUSION: The results of this BGOG study show disease-free and overall survival rates after robot-assisted laparoscopy in early-stage cervical cancer that are at least similar to previous reported recurrence and survival data. We expect that the results of the Robot-assisted Approach to Cervical Cancer trial will elucidate the place of robot-assisted laparoscopy in early-stage cervical cancer.
