In addition, patients with longer survival had higher frequencies of tumor-infiltrating non-proliferating (Ki-67−) conventional and regulatory (Foxp3+) CD4 T cells (Extended Data Fig. 6e and Supplementary Table 8) and lower frequencies of infiltrating proliferating (Ki-67+) CD4 T cells (Supplementary Table 8). This evidence concerns the gene FOXP3 and neoplasm.
