RESUMEN
OBJECTIVES: Cancer is the second leading cause of mortality in the world, and represents an economic, social and psychological burden. Scientific studies have focused on psychosocial coping mechanisms of patients and on factors improving their quality of life. Thus, the aim of the present study is to analyze the influence that spirituality would have on the quality of life of Lebanese cancer patients and to identify whether the influence on quality of life is mediated through a decreased depression. METHODS: This is a cross-sectional study targeting cancer patients in the hemato-oncology department of the Hôtel-Dieu de France Hospital (Beirut, Lebanon). It is based on a questionnaire composed of three parts: EQ-5D-5L, PHQ-9, and FACIT-Sp-12. Likewise, a control group suffering from chronic diseases and treated in the hospital was questioned. Univariate and multivariate analysis were conducted to assess the relationship between the different questionnaires for controls and for cancer patients. RESULTS: Thirty-nine cancer patients and eight control patients were questioned. In the univariate analysis, there was no relationship between depression and spirituality nor for spirituality and quality of life. After controlling for depression, an inverse correlation between quality of life and spirituality was shown. CONCLUSIONS: Our study is a pilot study which for the first time investigates the implication of depression in a "spirituality-quality of life" association. There is no clear association of spirituality with quality of life. In fact, the physical and psychological burden of chronically ill patients could exceed and render insignificant a possible impact of spirituality on quality of life.
