摘要:

目的 探讨乳腺癌患者活检组织石蜡标本中P53表达的变化及其在监测乳腺癌患者复发转移及预后中的意义。方法 采用免疫组化SP染色法和原位杂交法同时检测88例乳腺癌患者的活检组织石蜡标本中P53的表达情况,结合患者的转移复发情况分析P53表达水平与乳腺癌患者预后的关系。结果 免疫组化SP染色法结果显示P53高表达者27例,低表达者43例;原位杂交法结果显示P53高表达者28例,低表达者42例。2种检测方法P53高表达符合率为100%。P53高表达者对化疗的敏感性及5年生存率均明显低于P53低表达者(P<0.05),而P53高表达者的复发率、转移率明显高于P53低表达者(P<0.05)。结论 P53或可作为评估乳腺癌复发、转移和患者5年生存率的独立指标之一。

Abstract:

Objective To investigate the change of P53 expression in paraffin biopsy specimens of breast cancer patients and its role in monitoring recurrence,metastasis and prognosis of breast cancer patients. Methods Immunohistochemical SP staining and in situ hybridization were used to determine the expression of P53 in paraffin biopsy specimens of 88 patients with breast cancer. The relationship between the expression of P53 and the prognosis of patients with breast cancer was analyzed according to clinical metastasis and recurrence. Results Immunohistochemical SP staining showed that P53 was overexpressed in 27 cases and underexpressed in 43 cases. In situ hybridization showed that P53 was overexpressed in 28 cases and underexpressed in 42 cases. The consistency rate of high P53 expression between the 2 methods was 100%. The sensitivity to chemotherapy and 5-year survival rate of patients with high P53 expression were lower than those of patients with low P53 expression(P<0.05),while the recurrence and metastasis rates of patients with high P53 expression were higher than those of patients with low P53 expression(P<0.05). Conclusions P53 may be an independent indicator for evaluating the recurrence,metastasis and 5-year survival of breast cancer patients.
