Use of Temporary Percutaneous Peripheral Nerve Stimulation in an Oncologic Population: A Retrospective Review

Objectives: Patients with an underlying cancer diagnosis may experience pain from many sources. Temporary, percutaneous peripheral nerve stimulation (PNS) is a minimally invasive procedure that can control pain in those who have failed conservative management. The purpose of this retrospective review is to show the use of PNS in managing pain in the oncologic setting. Materials and methods: Temporary, percutaneous PNS was placed under fluoroscopic or ultrasound guidance for 15 patients at a cancer pain facility. Cases were grouped by subtypes of cancer pain (ie, tumor-related, treatment-related, cancer-associated conditions, and cancer-independent). Before PNS, patients were refractory to medical management or previous interventional treatments. Patients were observed with routine clinic visits to monitor pain levels via visual analog scale (VAS) and quality-of-life measures. PNS was removed after the indicated 60-day treatment period. Results: This retrospective review presents ten successful cases of oncologic-related pain treated with PNS. Patients with subtypes of pain that were tumor related, from cancer-associated conditions, and cancer independent all experienced a similar degree of pain relief. However, patients with cancer-treatment–related pain experienced the least analgesia from PNS. We also present six cases in which PNS did not provide adequate pain relief. Conclusion: PNS is an emerging technology in neuromodulation that may be useful in managing pain, especially in the oncologic population. Patients with cancer-related and non–cancer-related pain localized to a specific nerve distribution should be considered appropriate candidates for PNS. Further research is needed to optimize patient selection and indications for PNS in the population with cancer.
