As the risk-benefit profile of anti-inflammatory drugs in cancer survivors (CS) is unclear, GPs and patients could benefit from alternative non-pharmacological treatment options for dysregulated inflammation. There is a potential for home built environment (H-BE) interventions to modulate inflammation, however, discrepancies exist between studies.Aim To evaluate the effectiveness of H-BE interventions on cancer-associated inflammation biomarkers.Design & setting A systematic review and meta-analysis of randomised and non-randomised trials in community-dwelling adults.Method PubMed-Medline, Embase, Web of Science, and Google Scholar will be searched for clinical trials published in January 2000 onwards. We will include H-BE interventions modifying air quality, thermal comfort, non-ionising radiation, noise, nature and water. No restrictions to study population will be applied to allow deriving expectations for effects of the interventions in CS from available source populations. Outcome measures will be inflammatory biomarkers clinically and physiologically relevant to cancer. The first reviewer will independently screen articles together with GPs and extract data that will be verified by a second reviewer. The quality of studies will be assessed using the Cochrane Risk-of-Bias tools. Depending on the clinical and methodological homogeneity of populations, interventions, and outcomes, we will conduct a meta-analysis using random-effects models.Conclusions Findings will determine the effectiveness of H-BE interventions on inflammatory parameters, guide future directions for its provision in community-dwelling CS and support GPs with safer anti-inflammatory treatment options in high-risk patients for clinical complications.
