The immunoreactivities of CYLD were seven (17.9%) negative, twenty-six cases (66.7%) were score = 1, and six (15.4%) were score = 2 in NPC tumors, whereas eight (22.2%) cases were score = 1, twenty-one (58.3%) were score = 2, and seven (19.4%) were score = 3 in adjacent nasopharyngeal epithelium (Fig. 4D).
