Abstract

Background: There are limited data comparing the prognosis and fertility outcomes of the patients with early cervical cancer treated by trans-vaginal radical trachelectomy (VRT) or abdominal radical trachelectomy (ART).The objective of this study was to compare the surgical and pathologic characteristics, the prognosis and fertility outcomes of the patients treated by VRT or ART.

Methods: Matched-case study based on a prospectively maintained database of patients underwent radical trachelectomy in 10 centres of China was designed to compare the prognosis and fertility outcomes of the patients treated by VRT or ART.

Results: Totally 150 cases, 77 in the VRT and 73 in the ART group, were included. VRT and ART provide similar surgical and pathological outcomes except larger specimens obtained by ART. In the ART group, no patient developed recurrent diseases, but, in the VRT group, 7 (9.8%) patients developed recurrent diseases and 2 (1.6%) patients died of the tumours (P=0.035). The rate of pregnancy in the VRT group was significantly higher than those of ART (39.5% vs 8.8%; P=0.003). The patients with tumour size >2 cm showed significant higher recurrent rate (11.6% vs 2.4%, P<0.05) and lower pregnant rate (12.5% vs 32.1%, P=0.094) compared with the patients with tumour size <2 cm.

Conclusion: Patients treated by ART obtained better oncology results, but their fertility outcomes were unfavourable compared with VRT. Tumour size <2 cm should be emphasised as an indication for radical trachelectomy for improving the outcome of fertility and prognosis.
