Breakthroughs in thymic malignancies using international collaborative data

Thymic epithelial tumors (TET) are rare with an overall incidence of 0.15 per 100,000, however, the incidence appears to be increasing (1) ( Figure 1 ). Like many rare tumors, there has been a paucity of data from which to derive best practices, leading to the development of numerous muticenter large databases. These efforts allow for pooling of data and better characterization of the biology, clinical characteristics, and patient outcomes of thymic tumors.
