ABSTRACT

The efficacy of eculizumab as a perioperative treatment in patients with thymoma-associated myasthenia gravis (TAMG) has not been evaluated. This prospective study included patients with TAMG who received standard-of-care therapy (Soc group, n = 20) or combined with eculizumab (Ecu group, n = 13). At 1 week, the Ecu group showed a marked improvement compared to the Soc group, as evidenced by a reduction in Quantitative Myasthenia Gravis (QMG) (7.39 ± 3.47 vs 0.25 ± 5.13, P = 0.0001), Manual Muscle Test (MMT) (6.39 ± 4.66 vs 0.15 ± 3.96, P = 0.0003), and MG Activities of Daily Living (MG-ADL) (4.85 ± 3.16 vs 0.30 ± 3.47, P = 0.0006). No significant differences were observed in operative time, or intraoperative blood loss. The rate of postoperative myasthenic crisis was 9.1 % (1/13) in the Ecu group, compared to 20 % (4/20) in the Soc group (P = 0.33). This study highlights the role of eculizumab in TAMG as a rapid symptom-control treatment before thymomectomy.
