Management of specific symptom complexes in patients receiving palliative care.
During the past 10 years there have been major changes in the management of the most common symptoms of terminal cancer. Opioid agonists remain the mainstay in the management of cancer pain. Slow-release preparations are currently available for several of these agents. The increased use of opioids has led to the recognition of opioid-induced neurotoxic effects and to the development of effective adjuvant drugs and other strategies to counteract these side effects. A number of drugs are available for the management of symptoms of cachexia, including corticosteroids and progestational drugs. Prokinetic drugs, either alone or in combination with other agents such as corticosteroids, are highly effective in the treatment of chronic nausea. For patients with asthenia, it should first be determined whether there are any reversible causes; if not, corticosteroids and psychostimulants may diminish the symptoms. Haloperidol, other neuroleptics and benzodiazepines may be required to manage hyperactive delirium. Oxygen and opioids are effective in treating dyspnea, whereas there is limited evidence that benzodiazepines provide any relief of this symptom. More research on the assessment and management of these devastating clinical symptoms of cancer is badly needed.
