Abstract:
[Objective] To explore the number of examined lymph nodes (ELN) and positive lymph node ratio (LNR) in the prediction of 5-year and 10-year overall survival (OS) and cancer-specific survival (CSS) of prostate cancer (PCa) patients, so as to provide reference for clinical practice. [Methods] Information of PCa patients screened in the Surveillance, Epidemiology and End Results (SEER) database during 2010-2020 were analyzed. A total of 1842 PCa patients were assigned to the training set (n=1290) and validation set (n=552) in a 7∶3 ratio with R 4.3.0 software. Significant factors in the multivariate Cox proportional risk regression model were adjusted, restricted cubic spline plots (RCS) were plotted, the optimal cut-off values of ELN and LNR were determined, and the 5-year and 10-year OS and CSS were analyzed with restricted mean survival time (RMST). [Results] Multivariate Cox analysis showed that there was a 2.9% reduction in the risk of death with an increase of 1-unit ELN and a 3.1% reduction in the risk of cancer-specific death. There was a 481.4% increase in the risk of death with a 1-unit increase in LNR and a 667.5% increase in the risk of cancer-specific death. The risk of overall death and cancer-specific death in ELN and PCa patients showing a non-linear relationship (P<0.001), while in the LNR and PCa patients showing a linear relationship (P>0.05). RMST results showed that the optimal ELN range for evaluating OS was 12-29, the optimal ELN range for assessing CSS was 12-25, LNR>0.152 indicated poor prognosis. [Conclusion] We have clarified the range of ELN and LNR, which can provide reference for the clinical precision diagnosis and treatment of PCa.
