THYMOMA: A clinicopathological correlation of 1470 cases

We present 1470 surgical resections for thymoma identified in the pathology files of 14 institutions from 11 countries with the purpose to determine and correlate a simplified histological classification of thymoma and pathological staging with clinical outcome. The study population was comprised of 720 men and 750 women between the ages of 12 and 86years (average: 54.8years). Clinically 137 patients (17%) had a history of myasthenia gravis, 31 patients (3.8%) of other autoimmune disease, and 55 (6.8%) patients of another neoplastic process.
