[Surgical therapy for patients with thymoma or thymic carcinoma; based on WHO classification].

The treatment strategy for patients with thymoma or thymic carcinoma still has not been confirmed, and the molecular biologic characteristics of these tumors have not been defined also. We have emphasized the clinical significance of this classification so far by the research cooperation with professor Müller-Hermelink, the institute of pathology, Würzburg University. This time, We introduced clinico-pathological findings based on the new WHO classification in 59 Case of thymic epithelial tumor and reffered the treatment strategy for patients with thymic cancer.
