Tumours of the thymus: a cohort study of prognostic factors from the European Society of Thoracic Surgeons database

2151 cases of surgery for thymomas were analyzed based on a retrospective EACTS database. Recurrence rate and survival were negatively associated with Masaoka stages III–IV, incomplete resection and non-thymoma histology, whereas adjuvant therapy after complete resection correlated to improved survival.
