NCT06188494

CompletedN/A

Sponsor: AstraZeneca

Conditions: Breast Cancer

Countries: Egypt

Breast cancer is a major public health concern worldwide. In Egypt, it was the most diagnosed cancer among females in 2020 with an incidence rate of 32.4%. Its age-standardized incidence and mortality rates were 48.7 and 20.4 per 100,000 population, respectively. The status quo of HER2 testing in Egypt is that all breast cancer cases are tested for HER2 protein expression on the surface of tumor cells by immunohistochemistry (IHC), and only those with score 2 (equivocal) and selected cases of score 3 are subjected for further analysis using in-situ hybridization technique (ISH) to detect HER2 gene amplification in tumor nuclei.
