Abstract
Up to 30% of patients with cancer continue to suffer from pain despite aggressive supportive care. The present study aimed to determine whether cordotomy can improve cancer pain refractory to interdisciplinary palliative care. In this randomized controlled trial, we recruited patients with refractory unilateral somatic pain, defined as a pain intensity (PI) ≥4, after more than three palliative care evaluations. Patients were randomized to percutaneous computed tomography-guided cordotomy or continued interdisciplinary palliative care. The primary outcome was 33% improvement in PI at 1 week after cordotomy or study enrollment as measured by the Edmonton Symptom Assessment Scale. Sixteen patients were enrolled (nine female, median age 58 years). Six of seven patients (85.7%) randomized to cordotomy experienced >33% reduction in PI (median preprocedure PI = 7, range 6-10; 1 week after cordotomy median PI = 1, range 0-6; p = .022). Zero of nine patients randomized to palliative care achieved a 33% reduction in PI. Seven patients (77.8%) randomized to palliative care elected to undergo cordotomy after 1 week. All of these patients experienced >33% reduction in PI (median preprocedure PI = 8, range 4-10; 1 week after cordotomy median...Continue Reading
