Cancer patients and their caregivers in the face of opioid analgesic treatment - Opportunities and threats to the treatment process

Abstract

Failure to alleviate cancer pain may deteriorate mental functioning, increase depression symptoms, result in the clinical diagnosis of demoralization syndrome nonadherence of treatment, functioning discipline, which together, may precipitate desire for euthanasia. Increased incidence of pain in patients with advanced or terminal disease has been reported to range from 39% to 66.4% depending on the stage of the cancer being experienced. Further, the progressive aging of societies and increased life expectancy in cancer patients has changed the dynamics of modern treatment processes. Despite their efficacy, the use of opioids as an analgesic treatment during terminal disease has been affected by the quality, availability, and negative reputation of these scheduled drugs. This review aims to describe the specific factors and limitations of opioid pain management from the perspective of patients and their caregivers. Further, we aim to identify and discuss the key factors which determine the success or failure of opioid use for the treatment of pain with links to internationally recognized recommendations and current research.
