Stromal TILs, namely CD3, CD8, and CD45RO, were evaluated in the formalin-fixed paraffin-embedded (FFPE) tumor tissues by immunohistochemistry (IHC) as a percentage of area occupied by CD3, CD8, and CD45RO positive mononuclear inflammatory cells over the total intratumoral stromal area. The gene discussed is CD8A; the disease is neoplasm.
