Spinal Cord Stimulation for Chronic Pelvic Pain Secondary to Oncologic Complications: A Case Report

This case report presents the efficacy of spinal cord stimulation (SCS) in a patient with chronic, treatment-resistant pelvic pain secondary to oncologic complications and associated therapies. A 62-year-old male with a complex history of colorectal and prostate cancer, with metastatic involvement of the bladder and breasts, presented with severe, diffuse, generalized pelvic pain rated 10/10 in severity. The patient's pelvic pain was likely multifactorial in etiology, consisting of mixed neuropathic and nociceptive pain from extensive chemotherapy, radiation therapy, and surgery. He tried multiple conservative treatments, including opioids, IV ketamine infusions, and ganglion impar blocks, which provided only transient analgesia. The patient then underwent SCS implantation. After the procedure, he reported moderate improvement in his previously severe pre-procedural pain and continues to report sustained analgesia at his monthly follow-up visits.
