Negative affectivity, restriction of emotions, and site of metastases predict mortality in recurrent breast cancer

Objective: To assess whether negative affectivity and restriction of emotio ns predict survival time with recurrent breast cancer. Methods: Thirty-two patients with recurrent breast cancer, diagnosed 6-19 months earlier and st abilized using surgical, medical and/or radiation therapies, were enrolled. Cox regression survival analyses, including initial severity of metastases (RR = 4.3 [1.3-14.3]; p = 0.02), were used to explore the association of p sychological variables with survival. Results: Low chronic anxiety in the c ontext of low emotional constraint predicted low mortality (RR 0.07 [0.01-0 .52]; p = 0.007). However, patients with low chronic anxiety scores but wit h high constraint had higher mortality (RR = 3.7 [1.2-11.5; p = 0.02). High chronic anxiety, with or without high constraint, also predicted earlier d eath, as did high control of feelings. Conclusion: An integrated model of n egative affectivity in the context of restriction of emotions appears to st rengthen the prediction of survival based on severity of breast cancer meta stases.
