Associated factors of hope in cancer patients during treatment: A systematic literature review.

Abstract

To identify the associated factors of hope during treatment in cancer patients. Hope is very important to cancer patients at all stages of the disease process. Hope is seen as an important coping mechanism. Most research about hope in cancer patients considered the end of life or in palliative care. Several and different factors are associated with hope. It is not yet sufficiently clear which factors are associated with hope during the treatment. A systematic literature review of quantitative empirical studies on hope in cancer patients during treatment. Search in MEDLINE (PubMed interface), CINAHL (EBSCO interface), Psychinfo and Cochrane (January 2009-December 2018). Empirical quantitative studies were included regardless of the disease stage, written in English or Dutch, measuring hope from the perspective of cancer patients. Two authors independently screened all the studies and assessed their quality. Thirty-three studies were included. Positive relationship has been established between hope and quality of life, social support, spiritual and existential well-being. Hope appears to be negatively associated with symptom burden, psychological distress and depression. There appears to be no relationship between hope and demographic and clinical variables. The relationship between anxiety and hope remains unclear. Hope primarily seems to be a process that takes place in a person's inner being rather than being determined from outside. Health professionals may want to focus on the meaning of hope for cancer patients in relation to the associated factors. A better understanding of the meaning of hope during treatment can be of great value in supporting cancer patients with regard to treatment decisions, psychosocial support, the experienced quality of life and symptom burden and any wishes they may have with regard to advanced care planning.
