Most patients can be managed with pharmacological options but for some these pain control methods are inadequate. Ablative spinal procedures offer an alternative method of pain control for cancer patients with a terminal diagnosis that are failing to have their pain controlled sufficiently by other methods. This paper provides a review of ablative spinal procedures for control of cancer pain. Patient selection, surgical methods, outcomes and complicationsare discussed in detail for cordotomy, dorsal root entry zone(DREZ) lesioning and midline myelotomy. Cordotomy is primarily done by a percutaneous method and it is best suited for patients with unilateral somatic limb and trunk pain such as due to sarcoma. Possible complications include unilateral weakness possibly respiratory abnormalities. Approximately 90% of patients have significant immediate pain relief following percutaneous cordotomy but increasing portions of patients have pain recurrence as the follow-up period increases beyond one year. The DREZ lesion procedure is best suited to patients with plexus invasion due to malignancy and pain confined to one limb. Possible complications of DREZ procedures include hemiparesis and decreased proprioception. Midline myelotomy is best suited for bilateral abdominal, pelvic or lower extremity pain. Division of the commissure is necessary to address bilateral lower extremity pain. This procedure is relatively rare but published case series demonstrate satisfactory pain control for over half of the patients undergoing the procedure. Possible complications include bilateral lower extremity weakness and diminished proprioception below the lesion level. Unlike cordotomy and DREZ this procedure offers visceral pain control as opposed to only somatic pain control. Ablative spinal procedures offer pain control for terminal cancer patients that are not able to managed medically. This paper provides an in depth review of these pro展开更多
