This correlates with previous studies that show dual inhibition of CXCR4‐CXCL12 (AMD3100) and PD‐1‐PD‐L1 (PD‐1 antibody) pathways reduce immunosuppression within ovarian tumours allowing the recruitment of effector T cells and a reduction in tumour growth.47 Here, CD274 is linked to ovarian neoplasm.
