Does myasthenia gravis influence overall survival and cumulative incidence of recurrence in thymoma patients? A Retrospective clinicopathological multicentre analysis on 797 patients

our study showed that MG was significantly associated with female, lower age and B2-B3 thymoma; it demonstrated a slight protective effect on OS at the univariate analysis which was not confirmed in multivariate as well as no impact on CIR. Advanced tumor stages and thymic carcinoma histology for OS and induction therapy and advanced stages for CIR were negative prognostic variables.
