Surgical/radiological interventions for cancer pain.

Pain is a major morbidity associated with cancer and up to 20% patients require invasive procedures for pain relief. Ablative techniques can be directed towards the spinal cord and brain to palliate pain or modify its perception. Anterolateral cordotomy, myelotomy, DREZotomy and cingulotomy are useful interventions for the management of refractory cancer pain. Advanced imaging modalities, including intraoperative computed tomography (CT) guidance, have increased safety and efficacy of these interventions. In this paper, authors review the recent literature regarding surgical interventions for the management of cancer pain.
