Abstract

Background: Cancer pain, particularly neuropathic pain, remains a significant clinical challenge, often refractory to conventional analgesic therapies.

Case report: This case study aims to assess the efficacy of the Freedom® peripheral nerve stimulation (PNS) System in managing chronic intractable cancer-related neuropathic pain. This particular case was managed at a specialized pain management center with access to advanced neuromodulation technologies. A 41-year-old woman with ductal mammary carcinoma and pectoral metastasis experienced severe pain in the right arm unresponsive to conventional treatments. A Freedom PNS System was implanted at the brachial plexus using a permanent surgical technique. Following the implantation of the Freedom PNS System, the patient's pain score decreased from 9/10 to 2/10, the Oswestry Disability Index improved from 66% to 12%, and Euro Quality of Life 5-Dimension 5-Level Version utility indexes increased significantly.

Conclusions: This case study demonstrates that the Freedom externally powered PNS System can be an effective and safe treatment for chronic cancer pain.

外供电外周神经刺激与单独接收器在臂丛神经治疗疼痛由于转移性侵袭晚期乳腺癌：1例报告。

背景：癌性疼痛，特别是神经性疼痛，仍然是一个重要的临床挑战，通常对传统的镇痛疗法是难治的。病例报告：本病例研究旨在评估Freedom®外周神经刺激（PNS）系统治疗慢性难治性癌症相关神经性疼痛的疗效。这个特殊的病例在一个专门的疼痛管理中心进行管理，该中心拥有先进的神经调节技术。41岁女性导管性乳腺癌合并胸转移，右臂剧烈疼痛，常规治疗无效。Freedom PNS系统采用永久性手术技术植入臂丛。植入Freedom PNS系统后，患者的疼痛评分从9/10下降到2/10，Oswestry残疾指数从66%提高到12%，欧洲生活质量5维5级版本效用指数显著提高。结论：本案例研究表明Freedom外源性PNS系统是一种安全有效的治疗慢性癌性疼痛的方法。
