Abstract

Purpose: The aim of this study was to compare survival outcomes of open radical hysterectomy and minimally invasive radical hysterectomy (MIS) in early stage cervical cancer.

Methods: A retrospective analysis of 148 patients with stage IB1 - IIA2 cervical cancer who underwent either minimally invasive or open radical hysterectomy. Tumor characteristics, recurrence rate, disease-free survival (DFS), and overall survival (OS) were compared according to surgical approach.

Results: In total, 110 and 38 patients were assigned to open surgery and MIS groups. After a medical follow-up of 42.1 months, the groups showed similar survival outcomes (recurrence rate, DFS, and OS). However, in patients with tumor size >2 cm, recurrence rate was significantly higher in MIS group (22.5% vs 0%; p=0.008). And in patients with tumor size >2 cm, MIS group showed significantly poorer DFS than open surgery group (p=0.017), although OS was similar between the two groups (p=0.252).

Conclusion: In patients with tumor size >2 cm, MIS was associated with higher recurrence rates and poorer DFS than open surgery. However, in patients with tumor size ≤2 cm, MIS did not seem to compromise oncologic outcomes.
