乳腺癌中医证型与临床分期及分子标志物关系

目的:探讨乳腺癌中医证型与临床分期及雌激素受体(estrogen receptor, ER)、孕激素受体(progesterone receptor, PR)和癌蛋白C-erbB-2关系.方法:选择经病理证实、有完整资料的乳腺癌病例95例,辨证分为肝郁痰凝、冲任失调、正虚毒炽3种中医证型,采用免疫组织化学法对各证型的临床分期及其分子标志物ER、PR、C-erbB-2表达进行分析.结果:95例中,肝郁痰凝型为71例,占74.74%,冲任失调型为9例,占9.47%,正虚毒炽型为15例,占15.79%.Ⅰ期、Ⅱ期乳腺癌中以肝郁痰凝型居多,而Ⅲ期、Ⅳ期中正虚毒炽型所占比例高于肝郁痰凝型和冲任失调型.肝郁痰凝型ER阳性率与正虚毒炽型比较,差异无显著性(P=0.074);肝郁痰凝型ER阳性率与冲任失调型比较,差异有显著性(P=0.022).各证型PR、C-erbB-2阳性率比较,差异无显著性.结论:乳腺癌早期多为肝郁痰凝型,后期以正虚毒炽型为主.肝郁痰凝型ER表达水平高于冲任失调型,而PR、C-erbB-2的表达与中医证型无明显相关性.

Relationship between Syndrome Type of Traditional Chinese Medicine and Clinical Stage and Molecular Biomarkers in Breast Cancer

Objective: To investigate the relationship between the syndrome type of traditional Chinese medicine(TCM) and clinical stage and the expression of estrogen receptor(ER),progesterone receptor(PR) and C-erbB-2 oncoprotein in breast cancer.Methods: Ninety-five cases of breast cancer with conformed pathological test and intact data were selected,and differentiated into 3 syndrome types,namely,the stagnation of the liver-qi and phlegm stasis,the disturbance of Chong and Ren channels and the weakened body resista...
