Surgical approach and long-term clinical outcome in women with microinvasive cervical cancer.

ABSTRACT

AIM: To assess the efficacy and safety of conservative surgical approach for microinvasive cervical cancer with regards to cone margins status and lymph vascular space invasion (LVSI). PATIENTS AND METHODS: This was a multicentre retrospective cohort study of 153 women diagnosed with microinvasive cervical cancer over a 10 years period (1993-2003). RESULTS: In conservatively-treated women (n=80), neither cancer mortality nor disease relapse after 184.5 ± 20.5 months of follow-up was detected. Residual disease in women who underwent secondary surgery was significantly related to positive margins on the primary cone excision (p=0.005) while no correlation with LVSI emerged. CONCLUSION: Conization can represent the definitive treatment for stage IA1, if surgical margins are cancer-free, independently of LVSI. A conservative surgical approach could also be considered in women with IA2 cervical cancer when preservation of fertility is strongly requested. A close long-term surveillance should be scheduled for conservatively-treated women.
