Salivary gland carcinoma, including well-differentiated carcinoma (secretory carcinoma, acinic cell carcinoma, etc.), high-grade adenoid cystic carcinoma, and mucoepidermoid carcinoma, also show an increased level of FASN, suggesting its potential role as an indicator of cancer aggressiveness and differentiation (78). The gene discussed is FASN; the disease is cancer.
