The relationship between the ratios of TILs FOXP3+ /CD8+, FOXP3+/CD4+ and CD4+/CD8+ and tumor recurrence was analyzed and only high FOXP3+/CD8+ and high FOXP3/CD4 + ratios were found to be associated with a decreased recurrence-free survival (p = 0.02 and p = 0.036, respectively) [4]. Here, CD4 is linked to neoplasm.
