Surgical Approach and Long-term Clinical Outcome in Women with Microinvasive Cervical Cancer

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
