内容記述タイプ Abstract
内容記述 The aim of this study was to determine the expression of human epidermal growth factor receptor type 2 (HER2), epidermal growth factor receptor (EGFR), peroxisome proliferator-activated receptor γ (PPARγ), CD44 and androgen receptor (AR) in adenoid cystic carcinomas (ACC), carcinoma ex pleomorphic adenomas (CXPA) and mucoepidermoid carcinomas (MEC) of the salivary glands, to investigate their molecular difference and to estimate the availability of molecular-targeted and hormonal therapy in salivary-gland tumors. Forthy patients with a salivary gland tumor, diagnosed and treated at our hospital, were studied. On the basis of histopathology, 10, 19 and 11 patients were identified with ACC, CXPA and MEC, respectively. The associations between histological types were evaluated by the chi-square test. Differences were considered statistically significant at P < 0.05. HER2-positive expression was observed in 10% of ACC, 84% of CXPA and 18% of MEC. EGFR-positive expression was observed in 40% of ACC, 68% of CXPA and 91% of MEC. CD44-positive expression was observed in 40% of ACC, 47% of CXPA and 91% of MEC. PPARγ-positive expression was observed in 10% of ACC, 53% of CXPA and 18% of MEC. AR-positive expression was observed in 20% of ACC, 32% of CXPA and 9% of MEC. Compared with other histological types, CXPA demonstrated significant HER2 and PPARγ staining and MEC demonstrated significant EGFR and CD44 staining. The differences in expression of markers between histological types in our study suggests the possibility that HER2- and PPARγ-targeted therapy may be effective in CXPA, and that EGFR-target therapy may be effective in MEC of the salivary glands.
