Global Mapping of Interventions to Improve Quality of Life of Patients with Cancer: A Protocol for Literature Mining and Meta-Analysis.

Cancer led to nearly 10 million deaths in 2020, as reported by the World Health Organization (WHO). Consequently, both biomedical therapeutics and psychological interventions have been implemented to decrease the burden of this non-communicable disease. However, the research conducted so far has only described some aspects of these interventions, which may increase the health-related quality of life of cancer patients. Therefore, a systematic review is necessary to depict an overall picture of the cancer interventions globally. Then, the impact of these interventions on the preference-based health-related quality of life of cancer patients may be synthesized. The protocol is developed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Web of Science database is used to retrieve the literature using four keyword terms: quality of life (QoL), cancer, interventions, and health utility. Then, we draw the global mapping diagram and conduct the meta-analysis for this research. Additionally, longitudinal measurements are used to estimate the changes in the health utility of patients during the interventions. Thus, this systematic review can provide insight into the impact of interventions on increasing the health-related quality of life (HRQL) of cancer patients.
