[Salvage Surgery Following Chemoradiotherapy for Thymic Basaloid Cell Carcinoma].

We performed salvage surgery after chemoradiotherapy(CRT) in a patient with thymic basaloid cell carcinoma. A 46-year-old man with an abnormal chest shadow on X-ray findings was referred to our hospital. Computed tomography revealed a partially solid tumor along with a multilocular cyst in the anterior mediastinum with mediastinal lymph node swelling infiltrating to the superior vena cava(SVC). Positron emission tomography revealed FDG accumulation (SUVmax 7.94)in the tumor. Pathological findings of a tumor biopsy specimen obtained by thoracoscopy led to a diagnosis of thymic basaloid cell carcinoma. Following CRT (ADOC+RT:60 Gy), a complete resection (R0)with replacement of the SVC was performed. The postoperative course was uneventful, and the patient was alive at 20 months after surgery with metastasis to the cervical lymph nodes and bone.
