ABSTRACT：Objective

To explore the value of preoperative neutrophil-to-lymphocyte ratio （NLR） and platelet-to-lymphocyte ratio （PLR） in the prediction of inguinal lymph node metastasis of penile cancer to provide a new idea for the clinical evaluation.

Methods A total of 48 patients with penile cancer who received surgical treatment in our hospital during Jan. 2016 and Dec. 2021 were selected and divided into the metastatic group （n=19） and non-metastatic group （n=29）. The number of neutrophils， lymphocytes and platelets were recorded， and NLR and PLR were calculated. The value of NLR and PLR in predicting inguinal lymph node metastasis was analyzed with receiver operating characteristic （ROC） curve. The correlation between NLR and PLR was determined with Pearson correlation analysis. Results The levels of NLR and PLR were significantly higher in the metastatic group than in the non-metastatic group （P<0.05）. ROC curve showed that the optimal cut-off value of NLR was 2.39， the area under the ROC curve （AUC） was 0.838 （95%CI：0.730-0.947）， with sensitivity of 94.7% and specificity of 58.6%， respectively. The optimal cut-off value of PLR was 113.66， the AUC was 0.755 （95%CI：0.618-0.892）， with sensitivity of 89.5% and specificity of 58.6%， respectively. The AUC of the two combined together was 0.851 （95%CI：0.747-0.956）， with sensitivity of 89.5% and specificity of 69.0%. The Pearson correlation analysis showed that NLR was positively correlated with PLR in patients in both groups （r=0.504， r=0.645， P<0.05）.Conclusion Preoperative NLR and PLR levels are significantly increased in patients with penile cancer，and the combination of the two indexes can predict the possibility of inguinal lymph node metastasis.
