Different serum levels of miRNAs in NPC patients with or without recurrence or distant metastasis. Data showed that the difference in the expression level of miRNA-26b, miRNA-29a and miRNA-125b was not significant when NPC with recurrence or distant metastasis and without before CCRT were compared. Whereas the difference in the expression level of miRNA-143 and miRNA-29b was not significant between the two groups after CCRT. The experiment was conducted in triplicate and the relative expression level in each miRNA were normalized to miRNA-16. * P < 0.05 versus NPC cases of clinical remission patients
