原发性乳腺癌 (PBC) 的 HER-2/neu 状态通过免疫组织化学和荧光原位杂交确定。然而,由于多种技术因素,PBC可能无法准确反映转移肿瘤的HER-2/neu状态。最近发布的指南建议,如果 30% 或更多的细胞为 3+,则将肿瘤定义为 HER-2/neu 阳性。可以使用美国食品和药物管理局批准的测试来测量血清中 HER-2 胞外结构域的循环水平,并且血清 HER-2/neu 水平增加至 15 ng/ml 以上可以反映肿瘤进展。还回顾了比较转移性乳腺癌患者 PBC 组织 HER-2/neu 状态和 HER-2/neu 水平高于 15 ng/ml 的研究。
HER-2/neu status of the primary breast cancer (PBC) is determined by immunohistochemistry and fluorescent in situ hybridization. Because of a variety of technical factors, however, the PBC may not accurately reflect the metastatic tumor in terms of HER-2/neu status. Recently published guidelines recommend that tumors be defined as HER-2/neu positive if 30% or more of the cells are 3+. Circulating levels of the HER-2 extracellular domain can be measured in serum using a test cleared by the US Food and Drug Administration, and increased serum HER-2/neu levels to above 15 ng/ml can reflect tumor progression. Studies comparing tissue HER-2/neu status of the PBC and HER-2/neu levels above 15 ng/ml in metastatic breast cancer patients are also reviewed.
