Lymphadenectomy in Primary Fallopian Tube Cancer is Associated with Improved Survival
Primary fallopian tube cancer (PFTC) shares the same diagnostic and management guidelines with epithelial ovarian cancer (EOC). The LION trail raised concerns regarding the role of systematic pelvic and para-aortic lymphadenectomy during debulking surgery. We aimed to evaluate the significance of lymphadenectomy in PFTC survival. This retrospective study analyzed the clinical features and survival of patients with PFTC who underwent primary surgery in our center between January 2013 and October 2020. Sixty-one patients diagnosed with PFTC were included in the study. Twenty-five (41.0%, 25/61) were diagnosed with FIGO (International Federation of Gynecology and Obstetrics) stages I/II and 36 (59.0%, 36/61) were diagnosed with stage III/IV. Twenty-nine (47.5%, 29/61) underwent pelvic lymphadenectomy with or without para-aortic lymphadenectomy, among which 12 (41.4%, 12/29) had lymph node metastasis confirmed by postoperative pathology. The mean progression-free survival was 60.4 months in the lymphadenectomy group and 37.8 months in the no-lymphadenectomy group ( PFTC is often diagnosed earlier and has a better prognosis than EOC. Most patients with PFTC would benefit from lymphadenectomy. However, the extent to which this association translates to a more diverse population needs to be further identified.
