The traits positively correlated with thyroid cancer include the following: B cell panel: Memory B cell %lymphocyte, CD25 on IgD+ CD38dim, CD27 on PB/PC, CD38 on IgD‐ CD38dim; Treg panel: Activated and secreting Treg %CD4 Treg, CD28+ DN (CD4‐ CD8‐) %DN, CD28+ CD45RA+ CD8br %CD8br; Myeloid cell panel: CD33br HLA DR+ CD14‐ %CD33br HLA DR+; cDC panel: CD80 on plasmacytoid DC, CD80 on CD62L+ plasmacytoid dendritic cells (DC); TBNK panel: SSC-A on CD8br. This evidence concerns the gene CD27 and thyroid cancer.
