Abstract

The pleomorphic adenoma (PA) is the most common tumor of the salivary gland and although benign, it has chances of recurrence and malignant transformation to carcinoma ex pleomorphic adenoma (CXPA). The latter is an aggressive neoplasm occurring with metastasis and death in a large percentage of cases. Although both tumors have important discoveries in genetic and molecular areas, the changes found are focal and in specific genetic sites. There are still many questions about the diagnostic market, pathogenesis and target therapy of PA and CXPA. Since the pathogenesis of cancer is characterized by a complex mix of genetic and metabolic changes, we will study various metabolic pathways (glucogenesis, lipogenesis) through immunohistochemical markers. This way, in this project, we will study a group of PAs and CXPAs (subdivided according to histological type and degree of progression) through the immunohistochemical reaction. With this approach, analyzing metabolic changes involved in tumorigenesis PA, CXPA carcinogenesis and tumor progression, we intend to add knowledge to what is known today expecting to discovery markers for diagnosis, pathogenesis and target therapy.
