Complete Resection of Masaoka Stage IVb Thymic Carcinoma After Chemoradiotherapy

We report a case of Masaoka stage IVb thymic carcinoma that had metastasized to right supraclavicular lymph nodes, where it would have been difficult to achieve complete resection. Thus, we performed concurrent chemoradiotherapy, which decreased the tumor's size and facilitated complete resection. The patient had an uneventful postoperative course and 30 months of recurrence-free survival. Concurrent chemoradiotherapy followed by complete surgical resection may be a useful strategy in cases of stage IVb thymic carcinoma with supraclavicular lymph node metastasis.
