Abstract:

Objective To investigate the clinical value of serum inflammatory factors with prostate-specific antigen(PSA) and free prostate-specific antigen(f-PSA) in the auxiliary diagnosis of prostate cancer. Methods From July 2020 to November 2022,49 prostate cancer patients(prostate cancer group),50 prostate hyperplasia patients(benign prostate hyperplasia group) and 33 healthy subjects(healthy control group) were enrolled from Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital. The serum levels of tumor necrosis factor-alpha(TNF-α),interleukin(IL)-1β,interleukin-2 rceptor(IL-2R),IL-8,IL-10,PSA and f-PSA were determined,and the clinical data of prostate cancer patients were collected. The efficacy of single and combined determinations of various indicators in the diagnosis of prostate cancer was evaluated by receiver operating characteristic(ROC) curve. Results The serum levels of TNF-α and IL-8 in prostate cancer group were higher than those in healthy control group and benign prostate hyperplasia group(P<0.05). The serum levels of TNF-α in benign prostate hyperplasia group were higher than those in healthy control group(P<0.05). There was no statistical significance in serum levels of IL-1β,IL-2R and IL-10 among the 3 groups(P>0.05). The serum levels of TNF-α and IL-8 in prostate cancer patients with different ages,Gleason scores,TNM stages,the International Society of Urological Pathology(ISUP) grades,hypertension history,diabetes mellitus history and nerve invasion had no statistical significance(P>0.05). Using the healthy control group and the benign prostate hyperplasia group as control,ROC curve analysis results showed that the areas under curves(AUC) of TNF-α,IL-8,PSA and f-PSA single determinations for diagnosing prostate cancer were 0.704,0.642,0.892 and 0.811,respectively,and the AUC for the combined determination of TNF-α,IL-8,PSA,f-PSA and f-PSA/PSA ratio was 0.946,which was higher than the other AUC(P<0.05). Conclusions The combined determination of serum TNF- α,IL-8,PSA,f-PSA and f-PSA/PSA ratio can improve the diagnostic efficiency of prostate cancer.
