Because most cancer pain involves multiple anatomic sites, invasive techniques are intended to be analgesic adjuvants and not serve as the definitive treatment. These procedures often allow patients to reduce their dosages in their current drug regimens or to derive greater pain relief from their present doses in order to improve their quality of life. Medical care of the suffering pain patient requires a multimodality, multispecialty approach combining psychotherapy, social support, and pain management to provide the best possible quality of life or quality of dying.
