Abstract

Background: Pretreatment cognitive impairment in cancer patients is well established but unexplained. Similar cognitive compromise has been observed in post-traumatic stress disorder (PTSD) patients, and PTSD symptoms are a frequent concomitant of cancer diagnosis. We tested the hypothesis that pretreatment cognitive impairment is attributable to cancer-related post-traumatic stress.

Methods: Women aged 65 years or younger who were diagnosed with breast cancer (case patients) or had undergone negative routine breast imaging (control patients) at one of six participating breast centers underwent traditional and computerized neuropsychological testing, clinician-administered diagnostic assessment of stress disorders, and self-report assessments of cognitive function and depression. To minimize confounding, case patients were evaluated prior to any local or systemic treatment. Cognitive indices of case patients, control patients, and normative samples were compared. The patients' risk of overall cognitive impairment was determined. Linear regression and a mediation model were used to test the study hypothesis. All statistical tests were two-sided.

Results: The 166 case patients and 60 well-matched control patients showed near-identical deviations from population norms. Case patients scored worse than control patients on two of 20 cognitive indices (Go/Nogo commission errors, Go/Nogo omission errors). Self-reported cognitive problems were associated with Go/Nogo omission errors and more pronounced in case patients. Only PTSD symptoms (Beta = 0.27, P = .004) and age (Beta = 0.22, P = .04) statistically significantly predicted Go/Nogo errors. The effect of having cancer on Go/Nogo errors was mediated by PTSD symptoms. Case patients did not have an increased risk of overall cognitive impairment.

Conclusion: Prior to any treatment, breast cancer patients may show limited cognitive impairment that is apparently largely caused by cancer-related post-traumatic stress.
