Abstract
19619 Background: Elderly patients with cancer have potential for multiple geriatric syndromes that influence treatment and outcomes. No single clinical assessment tool has targeted all the major geriatric syndromes and their interaction on cancer management and outcomes. We developed WCAS to evaluate cognitive and physical function, risk of falls and gait disorders, polypharmacy, and medical comorbidities. Methods: Eighteen newly diagnosed patients with breast cancer (age 55–82), were enrolled prior to cancer treatment. Cognitive function was evaluated with a comprehensive battery of neuropsychological tests targeting the domains of memory, executive function, attention, language, and praxis. Physical function skills were assessed with novel performance-based tasks (e.g., bed-making) and computerized assessments of balance, gait and risk of falls. Cancer treatment included surgery in all patients with variable use of adjuvant radiation and medical therapy. WCAS was administered at baseline and at month 6. Results: Ten subjects have completed both baseline and month 6 visits. Surgical treatment occurred at a mean of ten days after baseline assessment (SD 6.7). The mean (SD) of the age, years of education and baseline Mini Mental Status Exam (MMSE) was 66 years (7.3), 15.2 years (3.7) and 29.3 (1.1). From baseline to month six assessment performance on the WAIS Digit Symbol test, a measure of working memory and processing speed, declined (mean change −11.7, p<0.01). Likewise, the performance on the WAIS letter number sequence test (mean change −1.3, p=0.09) and the MMSE (mean change −1.1, p=0.12) declined. Interestingly, four subjects with pre-existing hypothyroidism on replacement treatment showed a greater decline (p<0.01) in memory than those without this common condition. Conclusions: Findings indicate that breast cancer diagnosis and therapy can be associated with significant decline in aspects of cognition in older adults with cancer. These changes can last at least 6 months and are more pronounced in those with hypothyroidism. Larger, longer term prospective studies utilizing WCAS are necessary to confirm our preliminary findings. No significant financial relationships to disclose.
