To investigate the risk factors affecting the prognosis of penile cancer after surgery.
We retrospectively analyzed the clinical data on 112 cases of penile cancer treated in Weifang People's Hospital from January 2013 to December 2023. Using the Kaplan-Meier survival curve, χ2 test, Fisher's exact test, and univariate and multivariate Cox risk regression analyses, we compared the clinical characteristics among different groups, and determined the independent prognostic risk factors for cancer-specific survival (CSS) of the patients.
The 1-, 3- and 5-year CSS rates of the penile cancer patients were 78.2%, 66.1% and 63.7%, respectively. Kaplan-Meier analysis indicated a significant correlation of a higher neutrophil-to-lymphocyte ratio (NLR) with a lower CSS rate (P < 0.001). Multivariate Cox regression analysis showed high NLR (HR = 2.6; 95% CI: 1.031－6.558; P = 0.043) to be an independent risk factor for CSS.
Preoperative NLR is an independent risk factor for the prognosis of penile cancer. In addition, older age, farmer or worker occupation, lower education, preoperative lymphocyte-to-monocyte ratio (LMR)≤2.81, preoperative fibrinogen (FIB)≥3.41 g/L, advanced tumor stage and tumor differentiation are associated with the poor prognosis the malignancy.
