Prevalence of Luminal A, Luminal B, HER2 enriched and triple negative breast carcinoma in population of Sindh
A tertiary care hospital experience
Keywords:
breast carcinoma, breast cancer, immunohistochemicalAbstract
The incidence of breast cancer has increased significantly in Asian countries in comparison to Western countries, and it is now one of the leading causes of cancer-related death among women worldwide. Each year, 1.5 million women (25% of all cancer women) are diagnosed with BC around the world, and this number is expected to rise to 2.2 million by 2025. In particular, breast cancer shows biologic heterogeneity in terms of risk factors, natural histories, responses to therapy, and prognostic features that vary considerably between ethnic and geographical groups. Many studies have focused on the distinctions between tumor subtypes because of the importance they play in guiding therapeutic decision making in breast cancer. These factors include histological grade, tumor type and size, and the presence of lymph node metastasis. As a proxy for profiling gene expression, immunohistochemical examination of breast cancer tissue with various biomarkers is employed. This method is cheap, widely accessible, reliable, and technically not demanding. The purpose of this research was to analyze the relationship between molecular subtypes of breast cancer and certain pathological characteristics.
