Commentary on “Multidisciplinary tumor board decision-making for postoperative radiotherapy in thymic epithelial tumors: insights from the RYTHMIC prospective cohort”

Abstract

Thymic epithelial neoplasms, including thymoma, thymic carcinoma, and thymic neuroendocrine tumors, are rare intrathoracic malignancies that may act in an aggressive manner (1,2). At least 15 different stage classification systems for these lesions have been proposed and used to varying degrees clinically, most of which have been derived from small data sets (3). Until recently, the most widely used staging classifications were the Masaoka and Masaoka-Koga staging systems, both based on a single institution cohort of less than 100 patients.
