Abstract
To assess and compare the peri-operative, oncologic, and survival outcomes for women with cervical cancer (CC) treated with abdominal radical hysterectomy (ARH) versus robotic radical hysterectomy (RRH) approaches in Bulgaria. We retrospectively analyzed patients with histologically diagnosed CC operated via ARH or RRH methods during January-2008 to April-2019. The data analyzed include patients and tumor characteristics, peri-operative outcomes, and disease status. Kaplan–Meier method and Cox regression analysis were performed to determine disease-free survival (DFS) and overall survival (OS). There were consecutive 1347 patients (ARH = 1006, RRH = 341), which formed the basis of study analyses. Women in the RRH group had significantly shorter median hospital length-of-stay than ARH cases (7 vs. 11 days, p < 0.001), higher post-operative hemoglobin (116 vs. 108 g/L, p < 0.001), and fewer blood transfusions (7.3% vs. 21.5%, p < 0.001), respectively. The overall incidence of post-operative complications was also lower in the RRH vs. ARH group (2.1% vs. 9.4%, p < 0.001). Median follow-up time for ARH vs. RRH groups was 4.32 vs. 5.24 years, respectively (p < 0.001). Kaplan–Meier analysis demonstrated that the RRH cohort had a significantly higher survival rate compared to the ARH group (CC-specific death 8.5% vs. 16.5% respectively). Mean time to recurrence did not differ significantly in either surgical approach (p = 0.495). Cox multivariate regression showed no significant impact of surgical approach on DFS or OS. No significant difference in DFS or OS between ARH vs. RRH for CC was observed. RRH approach does not lead to inferior oncologic outcomes and is associated with better peri-operative outcomes. In regard to “all stages” of CC, we found robotic surgery safer compared to laparotomy, and thus consider RRH a better surgical treatment option for patients with CC.
