ABSTRACT
<p><b>OBJECTIVE</b>To study the Gleason histologic grading of prostate carcinoma in relation to the serum prostate-specific antigen (PSA) level and the PSA in situ of the tumor, and the immunohistochemical staining of basal cell-specific cytokertain(34 beta E12) and alpha-Methylacyl-CoA racemase(P504S) of the tumor.</p><p><b>METHODS</b>The serum PSA levels were measured in 40 cases of prostate carcinoma. The Gleason histologic grading was based on histopathologic examination of the tumors, and the immunohistochemical staining including PSA in situ (35 cases), 34 beta E12(12 cases) and P504S(10 cases) was examined.</p><p><b>RESULTS</b>The higher the Gleason histologic grading of prostate carcinoma, the higher the serum PSA level(P < 0.01), and the weaker the positive reaction of the immunohistochemical staining of PSA of the tumor(P < 0.05). And the tumor cells displayed positive reaction for P504S and negative for 34 beta E12.</p><p><b>CONCLUSION</b>The Gleason histologic grading of prostate carcinoma is positively related to the serum PSA level and negatively to PSA in situ of the tumor immunohistochemically. It is important to use immunohistochemical staining for 34 beta E12 and P504S in the pathologic diagnosis of prostate carcinoma.</p>
