Abstract Background Breast cancer may impair health-related quality of life (HRQoL). We examined the mediating role of coping style (CS) in the relationship between resilience, perceived social support (PSS), and HRQoL in newly diagnosed breast cancer patients in the Chinese mainland. Methods A total of 431 patients completed a survey at two hospitals in Shaanxi Province, China, using self-report measures assessing HRQoL, resilience, PSS, and CS. A one-sample t-test analyzed differences between resilience, PSS, and CS in breast cancer patients and the corresponding norm. Multivariate linear regression analyzed the independent predictors of HRQoL. The mediating role of CS between resilience, PSS, and HRQoL were investigated using structural equation modeling (SEM). Results Participants had significantly lower scores for resilience and PSS and higher scores for the avoidance and resignation CSs than their corresponding norm. SEM analysis showed resilience had significant direct effects on CS (B:0.66, 95% CI: 0.54, 0.77) and HRQoL [0.32 (0.12, 0.49)]. PSS had significant direct effects on CS [0.18 (0.06, 0.29)]. Resilience [0.32 (0.19, 0.53)] and PSS [0.09 (0.03, 0.18)] had significant indirect effects, and resilience [0.64 (0.56, 0.71)] had significant total effects on HRQoL. CS had significant direct and total effects on HRQoL [0.48 (0.30, 0.72)]. Conclusions Newly diagnosed breast cancer patients of mainland China had lower resilience and PSS and higher negative CSs. CS appeared to mediate the influence of resilience and PSS on HRQoL. Multimodal intervention programs focusing on CS might increase the influence of resilience and PSS on HRQoL in breast cancer patients.

44 Background: Using murine mammary tumor models, recent research conducted by our laboratory at the Sloan-Kettering Institute indicates that select neutrophils are mobilized and entrained by a primary breast tumor and uniquely have the capacity to inhibit metastatic seeding in the lung (Granot Z et al. unpublished). We sought to determine whether entrainment of cytotoxic neutrophils also occurs in blood samples from women with newly diagnosed breast cancer as contrasted to those garnered from healthy women. Methods: Subjects were 21 newly diagnosed pre-operative breast cancer patients without evidence of metastatic disease, 9 healthy female volunteers with no history of any cancer, and 3 patients with newly diagnosed DCIS. Neutrophils were purified from the blood samples. Cytotoxicity was evaluated by incubating isolated neutrophils with luciferase labeled MDA-MB-231 cells. Luciferase activity, as a reflection of % cell kill, was measured using a Bio-Tek microplate luminescence reader. Results: Significant cytotoxicity was notably observed when MDA-MB-231 cells were co-cultured with neutrophils purified from patients with invasive tumors. Pre-operative breast cancer patients (n=21) had a cell kill range of 0-30% (mean = 12.1%), whereas healthy subjects (n=9) had a cell kill range of 0.2-8% (mean = 2.6%), p<0.004. DCIS patients (N=3) had a cell kill range of 3-4% (mean = 2.7). Conclusions: To date, this preliminary work is the first to demonstrate the cytotoxic role of select neutrophils in the peripheral blood of breast cancer patients as contrasted with those from women without breast cancer. Further studies are needed to evaluate the prognostic and therapeutic role of cytotoxic neutrophils.
