摘要
目的探讨p53蛋白在三阴性乳腺癌中的表达及其临床意义。方法回顾分析本院252例三阴性乳腺癌中资料完整的42例乳腺癌组织中p53蛋白的表达状态,分析其与三阴性乳腺癌患者临床病理特征及疾病进展时间的关系。结果42例乳腺癌组织中p53阳性表达率为52.38%(22/42),其表达与年龄、肿瘤大小、淋巴结转移、月经状态无关(P〉0.05)。p53阳性组中位疾病进展时间(TTP)为15个月(95%:8.3~21.7),P53阴性组中位TTP为21个月(95%:10.3~31.7),差异有统计学意义(P〈0.05)。结论p53阳性的三阴性乳腺癌患者的TTP明显低于p53阴性组,p53阳性可作为判断三阴性乳腺癌患者预后的一个重要指标。
Objective To investigate the expression of p53 in triple-negative breast cancer and its clinical significance. Methods The expression of p53 was examined immunohistochemically in tissue samples of 42 patients with informative triple-negative (ER, PR and Her-2 negative) breast cancer. Results The rate of positive p53 expression was 52.38% (22/42), which had no correlation with age, tumor size, axillary lymph node metastasis, and menstrual status (P〉0.05). Median time to progress (mTTP) in p53 positive group was 15 months (95% CI: 8.3-21.7 months), while that in p53 negative group was 21 months (95% CI: 10.3-31.7 months; P〈0.05). Conclusion P53 expression can be used as a prognostic indicator for patients with triple-negative breast cancer.
