title: Molecular aspects of thymic carcinoma.
abstract: Thymic carcinomas are tumors of the anterior mediastinum derived from the epithelial cells of the thymic gland. Due to their low incidence they are often investigated in combination with thymomas under the rubric of "thymic epithelial neoplasms" and studies exclusively addressing thymic carcinomas are sparse. Thymic carcinomas are characterized by their histologic variability, often resembling tumors seen in other organ systems. This morphologic variation coupled with their rarity has prevented large scale research of these tumors and little is known about the etiology, biologic behavior or best treatment for thymic carcinoma. In recent years, attempts have been made to investigate the molecular characteristics of these tumors in the hope that molecular profiling can be used to predict the prognosis or lead to the development of new treatment strategies. Herein we provide an overview of the recent advances of the molecular analysis of thymic carcinoma with particular emphasis on the potential use for molecularly targeted therapies.
