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.本数据集源自一项大型纵向研究（longitudinal study），该研究旨在评估高致吐性化疗方案（highly-emetogenic chemotherapies）对癌症患者的治疗效应，共采集两个时间点的观测数据：化疗前（基线）与首次化疗输注后第5天（输注后）。具体而言，本数据集包含619名乳腺癌患者的社会人口学特征、治疗相关特征，以及针对焦虑与睡眠的患者报告结局测量（Patient-Reported Outcome Measures）指标。
