ERBB2 and neoplasm: About two-thirds (65.5%) of the tumours were either intermediate or high Scarff–Bloom–Richardson grade, consistent with regional epidemiology [22–24].This study highlights the molecular classification of breast carcinoma immunohistochemical subtypes into Lumina A (ER+/PR+), Lumina B (ER+/PR+/HER-2+), Basal-like (triple negative) and HER-2 enriched tumours, unlike most local studies in literature which provide hormone receptor stratification in isolated patterns, presenting an unorganised reference for comparison.
