Unilateral Lower Extremity Pain Due to Malignancy Managed With Cordotomy: A Case Report.

UNLABELLED

Cancer pain management is comprehensive, and it generally begins with pharmacotherapy in a step-wise approach per analgesic guidelines established decades ago by the World Health Organization. This analgesic ladder involves the prescribing of co-analgesics, adjuvants, and opioids, with each step depending on pain severity. Although the majority of cancer pain responds to this strategy, there exist patients who do not respond adequately or experience significant side effects or intolerance to pain medications. It is in these patients whom clinicians consider interventional approaches. One approach to manage unremitting unilateral malignant pain includes evaluation for cordotomy, which is an approach that has been effective in such cases. We present a patient with breast cancer metastatic to the pelvis, with associated severe pelvic and right lower limb pain. Due to progressive disease, her pain worsened despite aggressive opioid dose escalations. She ultimately underwent percutaneous left anterolateral cervical cordotomy for malignant right leg pain, resulting in complete resolution of leg pain. We propose that, in select patients with neoplasm-related pain, cordotomy may prove very effective.
