Clinical Outcomes in Early Cervical Cancer Patients Treated with Nerve Plane–sparing Laparoscopic Radical Hysterectomy

ABSTRACT Study Objective To explore the feasibility of nerve plane–sparing laparoscopic radical hysterectomy (NPS-LRH) as a simplified C1-type surgery for cervical cancer patients and to compare this technique with laparoscopic radical hysterectomy (LRH). Design A retrospective comparative study. Setting An academic tertiary hospital affiliated with the Chinese National Cancer Center. Patients Six hundred fifteen patients with Federation Internationale de Gynecologie et d'Obstetrique stage Ib and IIa cervical cancer who underwent laparoscopic radical hysterectomy between January 2010 and December 2017 were enrolled. Among them, 263 patients underwent the NPS-LRH surgery, and 352 patients underwent the LRH surgery. Intraoperative data and postoperative outcomes were compared between the 2 groups. Interventions NPS-LRH is a simplified type C1 procedure that preserves the ureteral mesentery and its nerve plane, whereas LRH is a type C2 procedure in the Querleu-Morrow surgical classification system. Measurements and Main Results There were no statistically significant differences in age, body mass index, Federation Internationale de Gynecologie et d'Obstetrique stage, tumor differentiation, pathological type, depth of invasion, lymphovascular space invasion, parametrial tissue invasion, lymphatic metastasis, neoadjuvant chemotherapy, or postoperative adjuvant radiotherapy and chemotherapy between the 2 groups. Compared with the LRH group, the NPS-LRH group had a shorter length of operation (238.7 ± 53.9 minutes vs 259.8 ± 56.6 minutes, p  Conclusion NPS-LRH is a simplified, safe, and feasible type C1 operation that had a shorter length of operation, less intraoperative bleeding, more resected lymph nodes, and better postoperative bladder function compared with the LRH group. Further studies are required to assess its benefits on rectal function and long-term prognosis.
