Lack of Survival Benefit of Para-Aortic Lymphadenectomy in Advanced Cervical Cancer

Abstract

Introduction: The presence of positive para-aortic lymph nodes in advanced cervical cancer remains the most important prognostic factor for survival and also defines the treatment. Our aim was to define the influence of staging para-aortic lymphadenectomy in patients’ survival. Material and Methods: The medical records of 74 patients with advanced cervical cancer (FIGO IIB-IVA) were reviewed. In 31 patients (41.9%), the assessment of lymph nodes was performed with imaging test (group 1) and in 43 (58.1%) within a surgical staging para-aortic lymphadenectomy (group 2). We compared both groups according to stage of disease, treatment, progression-free survival (PFS), and overall survival (OS). Results: The extended-field radiotherapy was performed in 44.2 and 19.4% of patients in surgical and imaging staging group, respectively (p = 0.045). The disease-free survival rate was 17.4 ± 17.4 months in group 1 and 14.4 ± 12.6 months in group 2 (p = 0.456). No differences in OS were found between these 2 groups (p = 0.676). Conclusions: Despite the higher diagnostic accuracy of surgical staging and the higher number of patient who received extended field radiotherapy, we did not find differences between the overall and PFS rates in both the studied groups. Further prospective study on a higher number of patients would be necessary.
