Abstract
BACKGROUNDS
There is still no consensus on the significance of Lymphadenectomy (LD) and the number of lymph nodes that need to be excised (ELNs) for adequate LD in patients with early-stage primary fallopian tube cancer (PFTC). Our endeavor is geared towards deepening comprehension of LD in early-stage PFTC and identify the optimal cut-off of ELNs.
METHODS
This SEER-based study analyzed the clinical data of patients with early-stage PFTC between 2000 and 2018. X-tile was employed to confirm the optimal cut-off of ELNs. The survival data between groups were analyzed by the Kaplan-Meier estimates, Log-rank test and Cox proportional hazards model.
RESULTS
There was significant improvement in both mean cancer-specific survival (CSS, p < 0.001) and overall survival (OS, p < 0.001) in LD group. Regardless of matched or not, LD was identified as an independent protective factor of CSS and OS. The optimal 3-year CSS-based cutoff of ELNs was 11 (p = 0.026) as determined by X-tile. Both the mean CSS (p = 0.001) and mean OS (p = 0.002) in adequate LD group (ELNs > 11, n = 574) were significantly longer than these in inadequate LD group (ELNs ≤ 11, n = 738). Adequate LD, FIGO stage, tumor grade and histology were significant prognostic factors for CSS and OS.
CONCLUSION
LD is an independent protective prognostic factor of patients with early-stage PFTC. The association between ELNs > 11 and an improved prognosis is evident. Future studies are needed to further clarify the results above.
