Interventional cancer pain therapies

Interventional pain therapies play a critical role in palliation of severe cancer pain. Anesthesiologists specializing in cancer pain management have developed minimally invasive techniques to: (1) optimize pain control; (2) minimize side effects, adverse outcomes, and costs; (3) enhance functional abilities and physical and psychological well-being; and (4) enhance the quality of life for cancer patients. A thorough understanding of the pathophysiology of the cancer pain is needed to implement interventional therapies. It is also important to understand the prognosis of the patient, associated comorbidities, and expectations of the patient and family. Interventional pain therapies are minimally invasive techniques that can be divided into direct drug delivery, neuroablation and neural blockade, and neurostimulation. © 2005 Elsevier Inc.
