Age and extent of surgery affect attention in women treated for breast cancer

Women treated for breast cancer have shown attentional fatigue manifested as a decreased capacity to concentrate or direct attention in daily life activities. This study was conducted to determine if age and extent of surgery increase the risk of early development of attentional fatigue in 74 women newly diagnosed with Stage I or II breast cancer. Measures of capacity to direct attention (CDA) were obtained at two time points, about 12 days before, and 15 days after, breast-conserving surgery or mastectomy. ANOVA showed significant age and age by time interaction effects (p < .05). Women aged 65-79 showed a significant mean decline (p < .05) in CDA over time regardless of extent of surgery. Women aged 46-64, who underwent mastectomy, showed a mean loss in CDA, whereas those having breast-conserving surgery showed a significant mean gain (p < .05). Women aged 25-45 showed no significant mean change in CDA over time. Older age and more extensive surgery increase the likelihood of loss of attention due, in part, to greater risk of attentional fatigue.
