Breast cancer patient characteristics and patient-reported outcomes at chemotherapy initiation

These data were collected as part of a larger longitudinal study aiming to examine treatment effects of highly-emetogenic chemotherapies among cancer patients at two timepoints: pre-chemotherapy (baseline) and 5 days after the first infusion (post-infusion). Specifically, this dataset includes sociodemographic and treatment characteristics and patient-reported outcome measures of anxiety and sleep among 619 breast cancer patients.
