CD8A and neoplasm: MVA for luminal tumours showed low CD8 to again be predictive of recurrence (HR 1.7, CI 1.1–2.6, p = 0.011, Table S9), whilst in triple-negative cancers, low PD-1 (HR 8.6, CI 2.3–31.5, p = 0.001) predicted recurrence in a final model adjusted for lymph node status, lymphovascular invasion and radiotherapy boost (Table S10).
