A polyclonal antihuman c-erbB-2 oncoprotein antibody recognized c-erbB-2 oncoprotein in routinely formaldehyde-fixed, paraffin-embedded specimens.
Specimens taken from 192 patients with Stage III squamous cell carcinoma of the cervix treated with radiation therapy alone were investigated for c-erbB-2 oncoprotein expression using an immunohistochemical method.
Cancer cells that were positive for c-erbB-2 oncoprotein showed a surface membrane staining pattern. Of the 192 patients, 143 were negative for c-erbB-2 oncoprotein, 12 were weakly positive or ambiguous, 31 were positive, and 6 were strongly positive. The 5-year survival rate of the 155 patients who tested c-erbB-2 negative or weakly positive was significantly better than that of the 37 patients whose results were positive or strongly positive (61% versus 41%, P = 0.022).
c-erbB-2 Oncoprotein expression in cancer cells may imply a poor prognosis for patients with Stage III squamous cell carcinoma of the cervix treated with radiation therapy alone.
一种多克隆抗人c-erbB-2癌蛋白抗体可识别常规甲醛固定、石蜡包埋标本中的c-erbB-2癌蛋白。
采用免疫组化方法对192例仅接受放射治疗的III期宫颈鳞状细胞癌患者的标本进行c-erbB-2癌蛋白表达研究。
c-erbB-2癌蛋白阳性的癌细胞呈现细胞膜染色模式。192例患者中,143例c-erbB-2癌蛋白阴性,12例弱阳性或结果不明确,31例阳性,6例强阳性。155例c-erbB-2检测为阴性或弱阳性患者的5年生存率显著高于37例结果为阳性或强阳性的患者(61%对41%,P = 0.022)。
癌细胞中c-erbB-2癌蛋白表达可能提示仅接受放射治疗的III期宫颈鳞状细胞癌患者预后不良。
