CT-guided percutaneous cordotomy for intractable pain in what is more than a disease: Lung malignancies

Abstract

Aim: Lung cancer is the leading cause of cancer-related mortality worldwide. Pain is a common problem in these patients, yet inadequate or dissatisfactory management is prevalent. MaterIal and Methods: Between 1987 and 2012, 224 patients with intractable pain were treated with computerized tomography (CT)- guided cordotomy. Among them, 210 had intractable pain due to malignancies. The majority of the cases were diagnosed as pulmonary malignancies (108 patients). Sixty-seven were pulmonary carcinoma, 26 mesothelioma and 15 Pancoast tumors. Results: After cordotomy, 98.13% of cancer patients reported initial pain relief. Minimum and maximum preoperative scores of the Karnofsky Performance Scale were 20 and 70, versus postoperative scores of 40 and 90 (p<0.001). The median preoperative VAS score was 8 (6-9). On the first postoperative day, the score dropped sharply to 0 (0-8) (p<0.001). In this selected series of 108 percutaneous cordotomy procedures, as well as in the total series of 224 patients, there was no mortality or major morbidity. Conclusion: CT-guided percutaneous cordotomy is an effective procedure that should be used in the treatment of cancer-related pain problems. We suggest that cordotomy should be preferred as soon as possible in patients who fail to respond to the classic analgesic therapy.
