CD8A and neoplasm: This demonstrated that the highest risk was seen with CD8-low, CD20-high expression, which over the whole cohort was over three times the hazard of LR compared to CD8–CD20-double-high tumours (HR 3.4, CI 1.6–7.1, p = 0.001), and more than twice the hazard in luminal-only tumours (HR 2.7, CI 1.2–6.2, p = 0.016).
