Abstract

A 74-year-old Asian man presented with sacral bone metastasis-related pain caused by a metastatic thymoma. Computed tomography revealed an approximately 6-cm sacral mass, which was confirmed as a metastatic thymoma. The patient was referred to our department and underwent stereotactic ablative radiation therapy (SABR) using volumetric modulated arc therapy and received a total dose of 35 Gy in five fractions. One year after SABR, the sacral lesion had decreased in size, and the pain medication was reduced. After two years, the patient no longer required pain medication, indicating successful management of bone metastases in recurrent Type A Thymoma.

摘要

一名74岁的亚洲男性因转移性胸腺瘤出现骶骨转移相关疼痛。计算机断层扫描显示骶骨有一个约6厘米的肿块，经证实为转移性胸腺瘤。该患者被转诊至我科，接受了容积调强弧形放疗的立体定向消融放疗（SABR），共5次分割，总剂量为35 Gy。SABR治疗一年后，骶骨病变大小减小，止痛药物用量减少。两年后，患者不再需要止痛药物，表明复发性A型胸腺瘤骨转移得到成功控制。
