Alcohol consumption in cancer patients receiving psycho-oncologic care analysis of socio-demographic, health-related and cancer-related factors.

Purpose: The carcinogenic effects of alcoholic beverages and the negative impact of alcohol consumption on cancer progression and treatment outcomes are well established in oncology research. Many cancer patients experience significant psychological distress, often manifesting as elevated levels of depression and anxiety. In the general population, alcohol consumption is commonly used as a coping mechanism for such distress. For cancer patients facing substantial psychological challenges, psycho-oncology care is available to help manage their symptoms and the overall impact of their condition. However, there is limited understanding of the alcohol consumption patterns in this particularly vulnerable group of patients, as well as the disease-related factors that may influence their drinking behavior. This study aims to examine the prevalence of potentially risky alcohol consumption in cancer patients receiving psycho-oncology care and to identify sociodemographic, health-related, and psychosocial factors associated with alcohol consumption after cancer diagnosis. By understanding drinking patterns and the factors associated with them, we aim to promote healthier behaviors and enhance treatment outcomes for cancer patients receiving psycho-oncology care.

Methods: A consecutive sample of 1.225 patients from the psycho-oncology outpatient clinic of the University Medical Center Hamburg Eppendorf (UKE) was analyzed with regard to their alcohol consumption behavior using the Alcohol Use Disorders Identification Test-Consumption Items (AUDIT-C). Self-report questionnaires were employed to assess sociodemographic, health-related, and cancer-specific information. For statistical analysis, multiple linear regression was utilized.

Results: In the sample of cancer patients receiving psycho-oncology support one in six of both female and male patients showed risky alcohol drinking behavior (e.g. AUDIT-C above three for women and four for men). In the analysis (R-Square: 0.056) male gender (regression coefficient B 0.686, 95% CI: 0.453-0.919) and patients reporting a higher physical health-related quality of life (SF8-PCS) (B 0.021, 95% CI: 0.011-0.032) were associated with higher levels of alcohol consumption, whereas having children (B -0.481, 95%CI: -0.700- -0.262) was associated with lower alcohol consumption. With regard to cancer type, a single-factor analysis of variance with gender as the centered covariate showed that patients with gastrointestinal cancer had had lower average consumption levels compared to the groups of patients with breast cancer, melanoma, genitourinary cancer, and lymphoma. Also, patients with sarcoma had lower average consumption levels than patients with lymphoma.

Conclusions: The results allow to identify patient characteristics and cancer types associated with higher or lower alcohol consumption levels and higher likelihood of risky consumption behavior in this sample of cancer patients receiving psycho-oncological support.

Implications For Cancer Survivors: Cancer patients are particularly susceptible to the hazardous effects of alcohol consumption. The results of this study help to identify cancer patients at risk of worsening prognosis due to alcohol consumption and to develop intervention programs to minimize alcohol consumption in this group.
