Abstract

The goal of this study was to estimate prevalence of HER-2 positive tumors in a population-based sample of 1026 women diagnosed in 2005 with early stage breast cancer. We modeled the relationship between patient and tumor characteristics and HER-2. HER-2 positive estimates were 19% for women aged ≤ 49 years and 15% aged ≥ 50 years. HER-2 varied by tumor grade and size in women aged ≤ 49 years but was not significant in multivariate analysis. Tumor grade and race were associated with HER-2 for women aged ≥ 50 years after controlling for other variables. HER-2 varies by age and by race and tumor in older women.

摘要

本研究的目的是在一个 2005 年确诊为早期乳腺癌的 1026 名女性的基于人群的样本中,估计 HER-2 阳性肿瘤的患病率。我们建立了患者和肿瘤特征与 HER-2 之间的关系模型。年龄≤49 岁的女性中 HER-2 阳性的估计值为 19%,年龄≥50 岁的女性中 HER-2 阳性的估计值为 15%。在年龄≤49 岁的女性中,HER-2 随肿瘤分级和大小而变化,但在多变量分析中无统计学意义。在控制其他变量后,年龄≥50 岁的女性中,肿瘤分级和种族与 HER-2 相关。在老年女性中,HER-2 随年龄、种族和肿瘤而变化。
