Psychosocial factors associated with quality of life in cancer patients undergoing treatment: an umbrella review.

BACKGROUND

Cancer treatment greatly impacts physical and psychological functioning of cancer patients, negatively affecting their quality of life (QoL). This Umbrella Review (UR) aims to systematically summarize psychological and social factors positively or negatively associated with QoL in cancer patients undergoing treatment.

METHOD

Four scientific databases (PubMed, Embase, Scopus, and PsycInfo) were searched to identify systematic reviews between 2012 and 2023 analyzing the relationship between QoL and psychosocial factors in cancer patients in treatment. The UR was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Joanna Briggs Institute (JBI) review guidelines. The methodological quality of the included studies was evaluated using Assessment of Multiple Systematic Reviews 2 (AMSTAR2).

RESULTS

Eighteen systematic reviews were included. The major psychological factors influencing QoL are depression, coping strategies, anxiety, and distress. Results also demonstrate the significant impact of social factors on QoL: perceived social support has a positive influence on QoL of cancer patients, while lowered social support, impaired social functioning, interactions, and role limitations worsen their QoL and overall well-being.

CONCLUSION

This UR provides a comprehensive overview of the psychosocial factors impacting QoL of cancer patients and serves as a prominent base for developing questionnaires and policies aimed at measuring QoL in cancer patients undergoing treatment. Moreover, the findings of the study can guide future research or the development of personalized clinical interventions aimed at improving QoL for this cancer population group.
