AimThe aim of this study is to describe the effects of percutaneous cervical cordotomy (PCC) on pain, opioid consumption, adverse events, and satisfaction in palliative care patients with cancer pain after PCC until end of life.MethodsThis is a prospective observational case series of 58 PCCs in 52 consecutive patients. Indication for PCC was unilateral cancer pain with a maximum numeric rating scale (NRS) of pain above 5 despite maximal conservative treatment. The PCC was fluoroscopy guided. A radiofrequency lesion was made at 95°C for 20 seconds. The pain location and pain scores, analgesic medication, the cranial and caudal borders of dermatomes hypoesthetic for pin pricks, dysesthesia, urinary retention, Horner's syndrome, muscle strength, Karnofsky performance scale (KPS) score, patient satisfaction, hospital anxiety and distress score (HADS), and RAND 36 score were evaluated at 1 day; 1 and 6 weeks; and 3, 6, 9, 12 18, and 24 months after PCC, or until death if death occurred during the follow-up period.ResultsPain relief after PCC was intense (change in median maximum NRS from 9 to 0) and persistent. Median opioid use per day was 240 mg (145 to 565 mg) before PCC and 55 mg (0 to 120 mg) after PCC. The upper and lower borders of dermatomes hypoesthetic for pin pricks were stable over time. The most common side effects were short-term (< 1 week) neck pain (28%), dysesthesia (40%), and mild loss of muscle strength (11%). Approximately 83% of the patients were satisfied or very satisfied with the results of PCC 1 week after the procedure, and this percentage remained high in the long term. There was no significant change in the KPS score, HADS, and RAND 36 score.ConclusionPercutaneous cervical cordotomy is an effective treatment for unilateral cancer pain. The reduction in pain, reduction in opioid consumption, and hypoesthetic area remain stable until death.© 2020 World Institute of Pain.
