Purpose To analyze the survival outcomes of patients in a Brazilian cohort who underwent minimally invasive surgery (MIS) compared with open surgery for early stage cervical cancer. Methods A multicenter database was constructed, registering 1280 cervical cancer patients who had undergone radical hysterectomy from 2000 to 2019. For the final analysis, we included cases with a tumor ≤ 4 cm (stages Ia2 to Ib2, FIGO 2018) that underwent surgery from January 2007 to December 2017. Propensity score matching was also performed. Results A total of 776 cases were ultimately analyzed, 526 of which were included in the propensity score matching analysis (open, n = 263; MIS, n = 263). There were 52 recurrences (9.9%), 28 (10.6%) with MIS and 24 (9.1%) with open surgery ( p = 0.55); and 34 deaths were recorded, 13 (4.9%) and 21 (8.0%), respectively ( p = 0.15). We noted a 3-year disease-free survival (DFS) rate of 88.2% and 90.3% for those who received MIS and open surgery, respectively (HR 1.32; 95% CI: 0.76–2.29; p = 0.31) and a 5-year overall survival (OS) rate of 91.8% and 91.1%, respectively (HR 0.80; 95% CI: 0.40–1.61; p = 0.53). There was no difference in 3-year DFS rates between open surgery and MIS for tumors ≤ 2 cm (95.7% vs. 90.8%; p = 0.16) or > 2 cm (83.9% vs. 85.4%; p = 0.77). Also, the 5-year OS between open surgery and MIS did not differ for tumors ≤ 2 cm (93.1% vs. 93.6%; p = 0.82) or > 2 cm (88.9% vs. 89.8%; p = 0.35). Conclusions Survival outcomes were similar between minimally invasive and open radical hysterectomy in this large retrospective multicenter cohort.
