Living with mesothelioma: a systematic review of mental health and well-being impacts and interventions for patients and their informal carers.

ABSTRACT

OBJECTIVES: Mesothelioma is an aggressive cancer predominantly affecting the lung and abdominal linings. It can have a unique impact on mental health and well-being (MHWB) due to its incurability, poor prognosis and asbestos-exposure causation. This review's aims were to identify/synthesise international evidence on mesothelioma's MHWB impacts; explore MHWB interventions used by patients and carers; and identify evidence of their effectiveness. DESIGN: Systematic review. DATA SOURCES Databases, searched March 2022 and March 2024, were MEDLINE; CINAHL; PsycINFO; Cochrane Library; ASSIA. ELIGIBILITY CRITERIA We included study designs focusing on psychological impacts of living with mesothelioma and MHWB interventions used by patients and informal carers, published in English since January 2002. DATA EXTRACTION AND SYNTHESIS: A team of reviewers screened included studies using standardised methods. Quality was assessed using validated tools Mixed-Methods Appraisal tool for primary research and Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews. RESULTS: Forty-eight studies met the inclusion criteria 20 qualitative, 16 quantitative, nine reviews, two mixed-methods, one combined systematic review/qualitative study. UK studies predominated. Many MHWB impacts were reported, including traumatic stress, depression, anxiety and guilt. These were influenced by mesothelioma's causation, communication issues and carer-patient relational interactions. Participants used wide-ranging MHWB interventions, including religious/spiritual practice; talking to mental-health professionals; meaning-making. Some strategies were presented as unhelpful, for example, denial. Participants reported lack of access to support. CONCLUSIONS: Most qualitative studies were rated high quality. The quality of the quantitative studies and reviews varied. The sparse literature regarding MHWB in mesothelioma means more research is needed into impacts on patients and carers, including trauma. To enable access to evidence-based support, research is recommended concerning MHWB interventions' effectiveness in mesothelioma. PROSPERO REGISTRATION NUMBER CRD42022302187.
