Background: In recent years, the incidence of prostate cancer(PCa) is increasing. Advanced PCa has a poor
prognosis and high cost, which seriously affects the quality of life of patients. Therefore, how to improve the
diagnosis rate and prognosis of early PCa is the focus of clinical research. This paper aims to investigate the value
of P504s, 34βE12, Ki-67 and prostate-specific antigen (PSA) in the diagnosis and prognosis of PCa.
Objective: To investigate the expression of P504s, 34βE12, Ki67 and PSA in prostate tissues and their clinical
Methods: Twenty four cases in the study group were selected from PCa confirmed by pathology in the urology
department of Chengde Affiliated Hospital from October 2018 to August 2020, and 33 cases of Benign Prostate
Hyperplasia (BPH) confirmed by pathology in the same period were selected as the control group.The expression
of P504s, 34βE12 and Ki-67 in prostate tissues were determined by immunohistochemistry.
Results: The positive expression rates of P504s, 34βE12 and TPSA or F/TPSA in PCa patients were 95.8%, 12.5%
and 87.5%, respectively. The positive rates in BPH patients were 9.1%, 93.9% and 27.3%,The difference between
the two groups was statistically significant (p<0.05). PCa bone or lymph node metastasis was positively correlated
with Ki-67 (r=0.423, p<0.05) and Gleason score (r=0.446, p<0.05), indicating a stronger correlation with Gleason
Conclusion: The combined detection of P504s, 34βE12 and PSA is helpful for the diagnosis and differential
diagnosis of PCa.High Gleason score and ki-67 expression may indicate high risk of PCa metastasis and poor
