Abstract

Purpose

The aim of this study was to assess the security of radical trachelectomy (RT) in the treatment of IA–IIA cervical carcinoma and conducted a new survey based upon the results of previous researches.

Methods

The PMC, PubMed, Web of Science, Cochrane and EMBASE databases were retrieved to collect prospective clinical controlled trials (CCTs) published from 1984 to 2018. The oncologic outcomes were evaluated by meta-analysis, trial sequence analysis (TSA) and statistical analysis.

Results

Five prospective CCTs were collected in this study. The recurrence rate and mortality of RT was similar to that of radical hysterectomy (RH), which was consistent with the oncologic outcomes of meta-analysis and TSA. Patients with tumors 2–4 cm in diameter were more likely to receive RH, which may be a potential factor in the higher rate of adjuvant chemotherapy in the this group, and RH was significantly associated with the risk of intraoperative blood transfusion. It is notable that considerable negative margin was achieved by radical abdominal trachelectomy (RAT), and the clinical effect of RAT was slightly better than that of radical vaginal trachelectomy (RVT). However, the TSA results showed that the cumulative cases were not up to the required sample size to obtain the true negative or positive results.

Conclusions

It is safe and effective for early-stage patients with cervical cancer whose lesions are less than 2 cm to receive RVT. For those patients with lesions 2–4 cm who desire fertility preservation and without any evidence of infertility, RAT can be a feasible alternative to RH under fully informed consent. However, more CCTs with larger sample size are still required for further validation.
