IL2RG and neoplasm: Considering the pivotal role of IL15c‐IL15Rβ/γc interaction in IL15‐mediated anti‐tumor immunity, we evaluated the association between transcription of IL15 (encodes IL15) and IL2RG (encodes IL15Rγc) genes with survival benefit in two cohorts of TNBC patients (Sabatier: 83 patients; METABRIC: 216 patients).
