ABSTRACT
<p><b>OBJECTIVE</b>To study the expression and significance of granulocyte-macrophage colony-stimulating factor (GM-CSF) receptors in human prostate cancer.</p><p><b>METHODS</b>SP immunohistochemical method was employed to investigate the expression of alpha subunit of GM-CSF receptors in 48 cases of primary prostate cancer, 20 benign prostate hyperplasia samples and four kinds of cancer cell lines K562, PC-3M, HL-60 and MCF-7.</p><p><b>RESULTS</b>The total positive percentage of GM-CSF expression in prostate cancer was 79.2%. The positive percentages in the groups with Gleason score 2-4, 5-8, and 9-10 were 75%, 82.3% and 81.2% respectively. The four kinds of cancer cell lines had prominent GM-CSF receptor alpha subunit expression.</p><p><b>CONCLUSION</b>It suggests that both hyperplastic and neoplastic prostate tissues are responsive to GM-CSF and the extensive expression of GM-CSF receptors is an important characteristic of prostate cancer.</p>
