Abstract

Background: Cancer treatment is often complicated by co-occurring substance dependence such as alcohol, cannabis, opioids, amphetamines, and tobacco. The objective of this study was to analyze the association between substance use (alcohol, cannabis, opioids, amphetamines, and tobacco) and mortality among cancer patients.

Methods: This retrospective study used de-identified data from the University of California, San Diego Health on 22,763 cancer patients aged ≥ 18 years. Substance dependance post-diagnosis was identified based on clinical observations from electronic health records. Tumor staging was determined using the TNM system, with missing data imputed via biomarker-based regression. Cox proportional hazards models were computed to assess severity-adjusted associations between substance dependance, by type, and mortality.

Results: Cannabis dependence was not significantly associated with mortality. Alcohol, tobacco, opioid, and amphetamine dependence were linked to increased mortality in both unadjusted and adjusted models. Adjusting for tumor stage reduced hazard ratios for opioid and tobacco dependence, suggesting stage as a confounding factor. Alcohol and opioid dependence remained significant predictors of mortality, while findings for cannabis and amphetamine were limited by small sample sizes.

Conclusion: Alcohol and opioid dependence in cancer patients was observed to be a significant predictor of mortality after adjusting for disease severity, emphasizing the need for targeted interventions among this subpopulation.

药物使用障碍对全系统癌症患者死亡率的影响。
背景:癌症治疗通常因同时发生的物质依赖而复杂化,如酒精、大麻、阿片类药物、安非他命和烟草。本研究的目的是分析药物使用(酒精、大麻、阿片类药物、安非他明和烟草)与癌症患者死亡率之间的关系。方法:这项回顾性研究使用来自加州大学圣地亚哥分校健康中心的去识别数据,研究对象为22,763名年龄≥18岁的癌症患者。诊断后的物质依赖是根据电子健康记录的临床观察确定的。肿瘤分期使用TNM系统确定,缺失数据通过基于生物标志物的回归输入。计算Cox比例风险模型来评估药物依赖(按类型)与死亡率之间经严重程度调整的关联。结果:大麻依赖与死亡率无显著相关。在未调整和调整的模型中,酒精、烟草、阿片类药物和安非他明依赖与死亡率增加有关。调整肿瘤分期降低了阿片类药物和烟草依赖的风险比,表明分期是一个混杂因素。酒精和阿片类药物依赖仍然是死亡率的重要预测因素,而大麻和安非他明的研究结果因样本量小而受到限制。结论:观察到癌症患者的酒精和阿片类药物依赖是调整疾病严重程度后死亡率的重要预测因子,强调需要对这一亚人群进行有针对性的干预。

期刊介绍: Psycho-Oncology is concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process. Psycho-oncology is an area of multi-disciplinary interest and has boundaries with the major specialities in oncology: the clinical disciplines (surgery, medicine, pediatrics, radiotherapy), epidemiology, immunology, endocrinology, biology, pathology, bioethics, palliative care, rehabilitation medicine, clinical trials research and decision making, as well as psychiatry and psychology. This international journal is published twelve times a year and will consider contributions to research of clinical and theoretical interest. Topics covered are wide-ranging and relate to the psychosocial aspects of cancer and AIDS-related tumors, including: epidemiology, quality of life, palliative and supportive care, psychiatry, psychology, sociology, social work, nursing and educational issues. Special reviews are offered from time to time. There is a section reviewing recently published books. A society news section is available for the dissemination of information relating to meetings, conferences and other society-related topics. Summary proceedings of important national and international symposia falling within the aims of the journal are presented.
