Long-term trajectories of self-reported cognitive function in a cohort of older survivors of breast cancer: CALGB 369901 (Alliance).

ABSTRACT:

Background

The number of survivors of breast cancer aged ≥65 years ("older") is growing, but to the authors' knowledge, little is known regarding the cognitive outcomes of these individuals.

Methods

A cohort of cognitively intact older survivors with nonmetastatic, invasive breast cancer was recruited from 78 sites from 2004 through 2011; approximately 83.7% of the survivors (1280 survivors) completed baseline assessments. Follow-up data were collected at 6 months and annually for up to 7 years (median, 4.1 years). Cognitive function was self-reported using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30); scores ranged from 0 to 100, with a higher score indicating better function.
