We analyzed the expression of CD8, CD4, Foxp3 and Tim-3 in lymphocytes, and of Galectin-9 in tumour cells between paired primary and recurrent NPC from 95 patients and we noted that there was significant increase in the expression of Galectin-9+ tumour cells (p < 0.001) and Foxp3+ lymphocytes (p < 0.001) but a significant decrease in the expression of CD8+ lymphocytes (p = 0.01) between paired primary and recurrent NPC. This evidence concerns the gene LGALS9 and nasopharyngeal carcinoma.
