metastin在乳腺癌的表达及临床意义

目的探讨K ISS-1基因编码产物m etastin在正常乳腺组织、乳腺良性病变、不同组织学类型乳腺癌中的表达及临床意义。方法应用免疫组化SP法检测正常乳腺组织12例、乳腺良性病变16例、不同组织学类型乳腺癌56例中m etastin的表达。结果m etastin在正常乳腺组织、乳腺良性病变、乳腺癌中的表达率分别是:75%、68.8%、30.4%;乳腺癌组织中M etastin的表达与乳腺良性病变组织、正常乳腺组织比较差异均有统计学意义(P<0.01);M etastin的表达均与乳腺癌的临床分期、淋巴结转移密切相关(P<0.01)。结论M etastin表达降低与乳腺癌转移密切相关,可能参与乳腺癌转移的调控。

The expression of metastin in breast cancer and its clinical significance

Objective To investigate the expression of metastin and its significance in benign breast disease,normal breast tissue and breast carcinoma.Methods SP immunohistochemistry was used to determine the expression of metastin in 16 benign breast disease,12 normal breast tissue and 56 breast carcinoma.Results The positive rates of metastin in benign breast disease,normal breast tissue and breast carcinoma were 68.8%,75% and 30.4%,respectively.The expression of metastin in breast carcinoma was much lower than that in benign breast disease and normal breast tissue(P<0.01).The expression of metastin in patients with breast carcinoma was correlated with its clinical stage and lymph node metastasis(P<0.01). Conclusion Metastin may play an important role in the metastasis of breast cancer,and may be involved in regulation of this process.
