Antitumor and antinociceptive approaches to control cancer pain.

Patients with cancer pain often present with specific clinical syndromes that allow specific anti-tumor approaches. If these approaches are not feasible, neurosurgical procedures for pain relief should be considered. The major advantage of neurosurgical procedures is freedom from the excessive side effects of narcotic therapy. The most durable pain procedure is cordotomy, while intraspinal narcotics offer a rational treatment alternative in selected patients. Spinal and plexopathy syndromes that are amenable to more specific anti-tumor therapy should be looked for, since newer surgical approaches offer the prospect of both pain relief and tumor control.
