摘要

Severe, treatment-resistant pain is a significant challenge for patients with cancer. Percutaneous Cervical Cordotomy (PCC) is an effective but underutilized procedure for managing severe cancer-related pain. PCC works by interrupting pain transmission through targeted lesioning of the lateral spinothalamic tract. This study aims to evaluate the efficacy and safety of PCC in treating cancer-related pain. A systematic search was conducted in PubMed, Scopus, and the Cochrane Database for randomized controlled trials evaluating PCC in cancer pain management. Studies were included if they reported outcomes on: (1) pain reduction (assessed via pain scales); (2) reduction in opioid use; (3) changes in Karnofsky Performance Status (KPS); and (4) adverse effects. 3A systematic search was conducted in PubMed, Scopus, and the Cochrane Database for randomized controlled trials evaluating PCC in cancer pain management.
