Advanced Masaoka-Koga stage as an independent predictor of thymoma recurrence after complete resection: myasthenia gravis was not an independent factor

Advanced Masaoka stage is the strongest independent predictor of thymoma recurrence after complete resection. Tumor size demonstrated a borderline association, suggesting a potential contributory role that requires further validation. MG, although clinically important for peri- and post-operative management, was not independently associated with recurrence.
