Abstract:
OBJECTIVETo explore the expressions of trefoil factor 1 (TFF1) and trefoil factor 3 (TFF3) in prostate cancer (PCa) and prostate intraepithelial neoplasia (PIN) and their clinical significance.
METHODSUsing immunohistochemistry, we detected the expressions of TFF1 and TFF3 in the prostatic tissues of 89 cases of PCa, 50 cases of PIN, and 65 cases of benign prostate hyperplasia (BPH), and evaluated their clinical significance.
RESULTSThe positive rates of TFF1 and TFF3 expressions were 77. 53% and 48. 31% in PCa and 66.00% and 30.00% in PIN, significantly higher than 49.23% and 13. 85% in BPH (P <0. 05). The expression of TFF1 was not correlated with Gleason score (P >0. 05), while that of TFF3 was significantly higher in the PCa cases with Gleason score ≤7 than in those with Gleason score > 7 (70. 00% vs 42. 03%, P <0. 05). No significant correlation was observed between TFF1 and TFF3 expressions in PCa (P >0. 05).
CONCLUSIONThe expressions of TFF1 and TFF3 may contribute to the occurrence and progression of PCa, and therefore could be used as laboratory indexes in the diagnosis, differential diagnosis, and prognosis of PCa.
