Nerve-sparing radical abdominal trachelectomy versus nerve-sparing radical hysterectomy in early-stage (FIGO IA2-IB) cervical cancer: A comparative study on feasibility and outcome

Objectives: Standard treatment in early-stage cervical cancer is a radical hysterectomy (RH) with pelvic lymphadenectomy. In women who wish to preserve fertility radical vaginal trachelectomy has been proposed; however, this is not feasible in larger tumors, and nervesparing surgery is not possible. Nerve-sparing radical abdominal trachelectomy (NSRAT) overcomes these disadvantages. Methods: Case-control study of women with early-stage cervical cancer (International Federation of Gynecology and Obstetrics IA2-IB) submitted to NSRAT from 2000 until 2011.Women submitted to nerve-sparing RH with early-stage cervical cancer were included as control subjects. Results: Twenty-eight patients and 77 control subjects were included. Neoadjuvant chemotherapy was administered in 3 women before NSRAT because the linear extension was or exceeded 40mm. Local recurrence ratewas 3.6%(95% confidence interval [CI], 0.00-10.6) in the NSRAT group compared with 7.8% (95% CI, 1.7-13.9) in the control group (P = 0.44). No significant difference was found between both groups regarding disease-free survival and survival. The overall pregnancy rate was 52.9% (95% CI, 28.7%-77.2%). The mean follow-up was 47.3 months (range, 6-122 months) for NSRAT and 51.8 months (11-129.6 months) for nerve-sparing RH. Conclusions: Nerve-sparing radical abdominal trachelectomy seems safe and effective in women with early-stage cervical cancer who wish to preserve fertility. Respective women should be informed about this treatment option, especially if the tumor is too large for radical vaginal trachelectomy.
