Prognostic and Safety Roles in Laparoscopic Versus Abdominal Radical Hysterectomy in Cervical Cancer: A Meta-analysis

OBJECTIVE Studies comparing the prognostic results between laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) in cervical cancer reported contradictory results. We aimed to evaluate the prognostic and safety roles of LRH by pooling studies in a meta-analysis. MATERIALS AND METHODS Original articles were searched in PubMed, EMBASE, and the Cochrane Library. The survival results (5-year disease-free survival [DFS], 5-year overall survival [OS], and recurrence rate [RR]), safety parameters (intra-, peri-, and postoperative complication rates and postoperative bowel or bladder recovery days), efficiency parameters (pelvic/para-aortic lymph nodes removed), and other parameters (operative time, estimated blood loss, and hospital of stay) between the two approaches were reviewed. RESULTS For the 2922 cases identified, DFS, OS, and RR did not differ in balanced prognostic factors, including lymph node metastasis, Stage IIB or above, non-squamous cancer histology, grade G3, lymphovascular space invasion, tumor size ≥4 cm, and positive parametrial and vaginal margin rates. Meanwhile, LRH was associated with higher complication rates and a shorter time to the recovery of bowel or bladder function than for ARH. The number of removed pelvic or para-aortic lymph nodes did not significantly differ. Other parameters showed LRH was associated with a longer operative time, less blood loss, and a shorter length of hospital stay. The survival and prognostic results did not differ in balanced prognostic factors. CONCLUSIONS LRH is safe and has lower operative complication rates than ARH.
