Comparison of Long-Term Survival of Total Abdominal Radical Hysterectomy and Laparoscopy-Assisted Radical Vaginal Hysterectomy in Patients with Early Cervical Cancer: Korean Multicenter, Retrospective Analysis.
Gynecologic oncology(2020)
Abstract
Purpose. The aim of this study was to compare survival outcomes of total abdominal radical hysterectomy (TARH) versus laparoscopy-assisted radical vaginal hysterectomy (LARVH) in stage IA2-IB2 cervical cancer. Methods. 812 patients who underwent RH between 2008 and 2017 were evaluated in 3 institutions. Progression-free survival (PFS) and overall survival (OS) were analyzed with Kaplan-Meier method and compared by log-rank test. The clinical noninferiority of the LARVH to TARH was assessed with a margin of -7.2%. Noninferiority was demonstrated if the low limit of 95% confidence interval (CI) exceeded its predefined margin. Results. 258 patients were treated with TARH and 252 patients with LARVH. TARH and LARVH group had similar 5-year PFS (84.4% vs 86.6%, p = 0.467) and OS rates (85.8% vs 88.0%, p = 0.919). Noninferiority of LARVH to TARH were confirmed with 5-year PFS and OS difference rates of 2.2% (95% CI-2.9-7.3, p = 0.001) and 2.2% (95% CI-2.7-7.1, p = 0.001), respectively. In subgroup of patients with tumors size >2 cm, 5-year PFS (77.6% vs 79.0%, p = 0.682) and OS rates (79.2% vs 81.5%, p = 0.784) did not differ statistically between the two groups. Noninferiority of LARVH to TARH were also confirmed with 5-year PFS and OS difference rates of 1.4% (95% CI-7.0-9.8, p = 0.046) and 2.3% (95% CI-5.8-10.4, p = 0.027), respectively. Conclusion. LARVH showed significant noninferiority for PFS and OS versus TARH in early cervical cancer, suggesting the potential oncologic safety of LARVH. (C) 2020 The Author(s). Published by Elsevier Inc.
