Abstract | The present invention relates generally to methods of accurately quantifying total HER2 or p95 expression in patients with advanced breast cancer and correlating HER2 or p95 expression with the risk of brain relapse and time to brain metastasis (TTBM).cndot. in such patients. Embodiments of the invention described herein include methods that utilize VeraTagg technology to accurately quantify total HER2 and p95 protein expression in tumor 30 samples and correlate HER2 level and the risk of brain relapse in HER2-positive advanced breast cancer patients, including patients that received treatment, such as trastuzumab. Embodiments of the invention include a novel assay that precisely quantifies total HER2 expression (H2T), p95 and HER2 homodimers (H2D) in biological samples.
La présente invention concerne de façon générale des procédés permettant la quantification précise de l'expression de HER2 ou p95 totale chez des patients présentant un cancer du sein avancé et une corrélation de l'expression de HER2 ou de p95 avec le risque de rechute au niveau du cerveau ou de métastases cérébrales chez lesdits patients. Des modes de réalisation de la présente invention comprennent des procédés qui utilisent la technologie VeraTag® pour quantifier précisément l'expression des protéines HER2 et p95 totale dans des échantillons tumoraux et corréler le niveau d'expression de HER2 et le risque de rechute au niveau du cerveau chez des patients atteints d'un cancer du sein avancé HER2-positif, notamment des patients ayant reçu un traitement, comme le trastuzumab. Des modes de réalisation de l'invention comprennent un nouveau dosage qui quantifie précisément l'expression de HER2 totale (H2T), des homodimères de p95 et HER2 (H2D) dans des échantillons biologiques. |
