    摘要:

    目的:研究活化的STAT3(pSTAT3)蛋白和STAT3 mRNA在皮肤黑素瘤和色素痣组织中的表达及其临床意义-方法:应用免疫组织化学S-P法检测90例皮肤黑素瘤和43例皮肤色素痣组织pSTAT3,原位分子杂交技术检测同一批组织STAT3 mRNA的表达情况,分析它们与患者临床病理特征的关系-结果:皮肤黑素瘤组织pSTAT3蛋白和STAT3 mRNA表达阳性率分别为56.7%和47.8%,显著高于色素痣的阳性率20.9%和23.3%(均P < 0.01); 黑素瘤pSTAT3蛋白和STAT3 mRNA表达均与肿瘤的厚度-浸润深度和淋巴结转移呈正相关(均P < 0.05);pSTAT3蛋白和STAT3 mRNA的表达呈显著正相关(r = 0.311,P < 0.01)-结论:皮肤恶性黑素瘤STAT3表达状况与肿瘤生长-侵袭和转移呈密切相关,提示STAT3可能在黑素瘤发生发展过程中发挥了重要作用-

    Abstract:

    Objective:To investigate the expression of pSTAT3 protein and STAT3 mRNA and their significance in cutaneous melanoma. Methods:The expression of pSTAT3 protein and STAT3 mRNA was examined in 90 cases of melanoma and 47 cases of nevus by immunohistochemistry and in situ hybridization, respectively. Results:The positive rates of pSTAT3 protein and STAT3 mRNA were 56.7% and 47.8%, which were significantly higher than those in the nevus. Both the expression of pSTAT3 protein and STAT3 mRNA were significantly correlated to depth of tumor invasion and tumor lymph node metastasis. Moreover, a significant correlation was found between the expression of pSTAT3 protein and STAT3 mRNA in melanoma. Conclusion:The expression of STAT3 was closely correlated to the tumor growth, invasion and metastasis, suggesting STAT3 might play an important role in the cutaneous melanoma development and progression.
