Abstract
Background Cancer is one of the major health problems worldwide, which in addition to physical disorders, causes stress and anxiety in patients and affects the quality of life of cancer patients. Mindfulness can affect stress and improve the quality of life. This research explained the correlation between stress, quality of life, and mindfulness. Materials and Methods Two hundred five cancer patients participated in this cross-sectional study. Patients completed the EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), the Mindfulness Attention and Awareness Scale (MAAS), and Perceived Stress Scale (PSS). Results Perceived stress and mindfulness predict nearly 39% of the changes of QOL in cancer patients. In addition, perceived stress was negatively associated with mindfulness and quality of life (P < 0.05). Mindfulness was positively correlated with quality of life (P < 0.05). Mindfulness played a mediating role in the relationship between perceived stress and quality of life (standardized β = −0.13; SE = 0.07, 95% confidence interval = −0.28 to −0.01; P value = 0.04). Conclusion In the present study, the variables of mindfulness and perceived stress affected the quality of life of cancer patients. Mindfulness can affect the quality of life of cancer patients directly and indirectly. These results emphasize the importance of mindfulness in the lives of cancer patients.
Highlights
Cancer is a major health problem worldwide, and the US has the second highest rate of victims [1]. e World Health Organization declared 10 million cancer patients in 2000, which is expected to go up to 15 million by 2020, with 60% of them in underdeveloped countries [2].Cancer and its treatments often cause physical and mental disorders in patients, and the biggest problem of the cancer patients is the stress and anxiety caused by the disease
Despite insufficient knowledge about specific mechanisms involved in stress-induced tumorigenic processes, clinical studies have shown that stress can lead to cancer progression [7]
Mindfulness can reduce stress and anxiety; improve sleep disorders; reduce depression and stress, self-harm, and aggressive behaviors, increase patience and relaxation in the treatment process; create enthusiasm and motivation to fight against disease; improve quality of life; reduce pain and suffering caused by illness; and strengthen the immune system [11, 12, 15,16,17,18,19,20,21,22,23]
