Abstract
PURPOSE: Chronic stress is associated with neuroimmune inflammation and adverse outcomes in breast cancer survivors. Some breast cancer survivors rely on religious and spiritual (R/S) variables to manage stress after breast cancer treatment. A spiritually based psychoneuroimmunological (PNI) model of health suggests that R/S variables influence neuroimmune activity; however, these associations are not well-established. A pilot study was conducted to assess the feasibility of studying associations between R/S variables and neuroimmune biomarkers in breast cancer survivors. METHOD: Salivary alpha-amylase (sAA) and interleukin-6 (IL-6) were sampled among women previously treated for breast cancer. The primary aim was to assess feasibility and acceptability of the sampling protocol. A secondary aim explored associations between sAA, IL-6, R/S variables, and health outcomes. RESULT: Forty-one women completed the study. Biomarker sampling yielded 246 acceptable specimens used for analysis. SAA was detectable in 96% of specimens and IL-6 was detectable in 44% of specimens. The R/S variables with the strongest associations to sAA were spiritual self-rank (rs = .39; p < .05) and forgiveness (rs = .40; p < .05). The R/S variable with the strongest association to salivary IL-6 was positive congregational support (rs = .42; p < .05). CONCLUSION: Feasibility and acceptability of the sampling protocol were confirmed. Reference ranges for sAA and IL-6 for female breast cancer survivors are presented. Results suggest that spiritual beliefs and religious practices are associated with neuroimmune activity, adding credence to a spiritually based PNI model of health. Findings lay the foundations for future R/S-based interventions to promote health and well-being in breast cancer survivors.
