We then performed immunohistochemical (IHC) staining and blinded scoring on formalin-fixed, paraffin-embedded (FFPE) surgically resected tumor specimens from PDAC patients treated at UMass Memorial hospital to assess the relationship between EZH2 expression, NKp46+ NK cells and CD8+ T cell numbers, and patient survival. The gene discussed is NCR1; the disease is neoplasm.
