An abundance of inflammatory CD45RA(−)FOXP3(lo) T cells was correlated with a better prognosis in colorectal cancer.76 Therefore, the distinct predominant subpopulations of FOXP3+TILs during the dynamic process of tumor formation and progression may account for the different influences on prognosis in SCLC. This evidence concerns the gene FOXP3 and small cell lung carcinoma.
