Bone metastases are a significant prognostic factor in the history of cancer and often involve pain and a great impairment of the quality of life. The complete resection of tumor tissue is increasingly performed in patients with solitary bone metastases, to improve the survival of patients and their functional outcomes Methods: We report the case of a 65-year-old man with a painful, massive, highly perfused osteolytic lesion localized at the proximal third of the humerus, associated with extensive lesions of the rotator cuff tendons was diagnosed with keratoblastic squamous cell lung cancer metastasis.
The patient underwent shoulder and proximal humerus reconstruction with inverse tumor megaprosthesis after embolization of the lesion. At 3 and 6 months FU, a nearly complete resolution of painful symptoms, a significant improvement in functional skills, and better execution of most of the activities of daily life have been reported.
Accordingly with the literature the inverse shoulder megaprosthesis seems able to restore a satisfactory function and the silver-coated modular tumor system appears as a safe and viable treatment option in metastases tumor of proximal humerus.
在癌症病史中，骨转移是一个重要的预后因素，常伴有疼痛和生活质量的严重下降。对于单发骨转移患者，越来越多地进行肿瘤组织的完全切除，以提高患者的生存率和功能预后。
我们报告了一例 65 岁男性患者，其肱骨近端出现疼痛、巨大、高灌注溶骨性病变，伴有广泛的肩袖肌腱病变，诊断为角化细胞样鳞状细胞肺癌转移。
患者在病变栓塞后接受了反向肿瘤假体的肩部和肱骨近端重建。在 3 个月和 6 个月的 FU 时，报告了疼痛症状几乎完全缓解、功能技能显著改善以及日常生活活动的大部分得到更好执行的情况。
根据文献，反向肩部假体似乎能够恢复满意的功能，而镀银模块化肿瘤系统似乎是肱骨近端转移瘤的一种安全可行的治疗选择。
