CCL27 and nasopharyngeal carcinoma: As shown in Fig. 1, the plasma levels of CCL27 in VCA-IgA–positive healthy donors (607.33 ± 218.81 pg/ml) were significantly higher than the pre-treatment levels in all NPC patients (437.09 ± 217.74 pg/ml, P < 0.0001) and the subset of patients with early stage NPC (Stage I + II, 463.85 ± 226.17, P = 0.0126).
