Sinonasal carcinomas: recent advances in molecular and phenotypic characterization and their clinical implications.
Sinonasal carcinomas are rare tumors with an aggressive clinical behaviour which frequently pose a number of problems regarding the interpretation of diagnostic findings and the treatment. In addition, in comparison with other malignancies of the head and neck region, an elevated fraction of sinonasal carcinomas can be attributed to occupational exposure. This review is focused on the recent advances in the molecular and phenotypic characterization of sinonasal carcinomas, and their possible implications for the interpretation of epidemiological data, as well as for the diagnosis and treatment of these rare malignancies. The increasing knowledge on their phenotypic and genotypic features is progressively leading to a refinement in diagnosis, especially for poorly differentiated and undifferentiated lesions, as well as to the identification of markers which can be potentially useful to identify the early phases of carcinogenesis, to detect subclinical disease, to predict the response to therapy, and finally, that may represent potential targets for alternative treatments.
