The diagnostic value of urine heat shock protein 70 and prostatic exosomal protein in chronic prostatitis

Clinical Application of Prostatic Exosomal Protein and Prostate-Specific Antigen Levels in the Detection of Prostate-Related Diseases

OBJECTIVE

Our aim was to study the use of prostatic exosomal protein (PSEP) and prostate-specific antigen (PSA) in diagnosis of prostate-related diseases.

METHODS

A total of 54 cases of acute prostatitis (AP), 72 cases of chronic prostatitis (CP), and 36 cases of prostate cancer (PCa) were enrolled. Levels of PSEP and PSA were analyzed.

RESULTS

The positive rate and level of PSEP in CP was highest (both P < .05). The total PSA (tPSA) level in PCa was the highest (P < .05), followed by AP and CP. The free PSA (fPSA) level was lowest in CP (P < .05); fPSA/tPSA in AP was the highest (P < .05). The PSEP level in type II CP was higher than in type IIIa and type IIIb (both P < .05), and it was higher in type IIIa than in type IIIb (P < .05). The tPSA level in type IIIb was the lowest in the 3 types (both P < .05). The fPSA/tPSA in type IIIb was the highest in the 3 types (P < .05).

CONCLUSION

The PSEP combined with PSA better distinguishes prostate-related diseases.
