BACKGROUND/METHODS: This study determines the co-expression of mammaglobin-A, vascular endothelial growth factor receptor-3 (VEGFR3) and Ki67 by immunohistochemistry (IHC) in tissue samples from 80 patients undergoing breast surgery (cancer or benign disease). The tissue expression was compared with the tumour histopathology and Kaplan Meier 5-year survival analysis was performed.
Positive breast tissue expression was observed in 53% samples for mammaglobin, 41% Ki67 and 65% VEGFR3 with a significant positive correlation between Ki67 and VEGFR3 co-expression. Ki67 and VEGFR3 expression correlated with the breast tumour grade and Ki67 expression also correlated with oestrogen receptor (ER) status. At 5 years post-operatively, 6/80 patients had died and 3 patients were alive but had cancer recurrence. High Ki67 expression significantly correlated with poor survival (disease-free and overall).
In this study, VEGFR3 and Ki67 expression but not mammaglobin-A correlated with breast tumour pathology. Positive Ki67 expression was also associated with a poor 5-year survival outcome.
背景/方法:本研究通过免疫组织化学(IHC)检测了80例接受乳房手术(癌症或良性疾病)患者的组织样本中乳腺珠蛋白-A、血管内皮生长因子受体-3(VEGFR3)和Ki67的共表达情况。将组织表达与肿瘤组织病理学进行比较,并进行Kaplan Meier 5年生存分析。
乳腺珠蛋白在53%的样本中呈阳性表达,Ki67在41%的样本中呈阳性表达,VEGFR3在65%的样本中呈阳性表达,Ki67与VEGFR3的共表达之间存在显著正相关。Ki67和VEGFR3的表达与乳腺肿瘤分级相关,Ki67的表达也与雌激素受体(ER)状态相关。术后5年,80例患者中有6例死亡,3例存活但出现癌症复发。高Ki67表达与较差的生存率(无病生存率和总生存率)显著相关。
在本研究中,VEGFR3和Ki67的表达与乳腺肿瘤病理学相关,而乳腺珠蛋白-A的表达与之无关。Ki67阳性表达也与较差的5年生存结果相关。
