Abstract:Although opioid analgesics are the cornerstone of cancer pain management, the stigmatization surrounding their use is severely hampering the standardization of treatment. This paper delves into the causes, manifestations, and clinical impacts of opioid-related stigma among cancer pain patients. This stigma arises from multiple factors, including policy restrictions, biased media coverage, knowledge gaps among healthcare professionals, and patients' misconceptions about the risks associated with opioid use. Specifically, the stigma manifests as public misunderstanding, patient internalized stigma, and structural barriers within the healthcare system. These interconnected dimensions of stigma mutually reinforce each other, creating a "stigma-inadequate treatment-worsening pain" vicious cycle that severely compromises patients' quality of life and health outcomes. Future research needs to develop standardized measurement tools for opioid use stigma, explore stigma characteristics across different subgroups, and construct multi-level destigmatizing intervention strategies to enhance treatment outcomes and quality of life for patients with cancer pain.
