ABSTRACT=Study Objective: To compare the surgical and oncologic outcomes between open abdomen radical hysterectomy (ARH) and laparoscopic radical hysterectomy (LRH) for cervical cancer.
Methods: Retrospective observational study with propensity score matching was used to ensure balanced groups for ARH and LRH. One-hundred-and-ninety-eight women with cervical cancer, 99 treated using ARH and 99 using LRH, between January 2012 and December 2014. Outcomes included disease-free survival (DFS), overall survival (OS), intra-operative factors, post-operator recovery, urinary retention, and adverse events. Moreover, the inverse probability of the treatment weighting (IPTW) method was also used.
Main Results: Compared with ARH, LRH was associated with a lower volume of blood loss (P < 0.001) and transfusion rate (P < 0.001), with a broader resection of the parametrium (P < 0.001). Post-operatively, the time to first flatus was shorter for LRH than ARH (P < 0.001) but the rate of urinary retention was higher for LRH (22.2%) than ARH (8.1%; P = 0.009). DFS and OS were similar between groups. By IPTW, laparoscopy was also not associated with poorer survival in terms of DFS (HR 1.52, CI 0.799–2.891, P = 0.202) or OS (HR 0.942, HR 0.425–2.09, P = 0.883).
Conclusion: Compared with ARH, LRH provided better intra-operative and post-operative outcomes, with no significant difference in oncologic outcomes and survival. Urinary retention remains a clinical issue to improve with LRH. The technology of LRH has been improved in China to address the inconsistent results of oncologic outcomes in previous studies. Whether these improvements could be effective needs to be investigated in the future.
