Popis: OBJECTIVES: Health-related quality of life (HRQoL) and ability to work in patients treated for HER2+ early breast cancer (EBC) are poorly understood. This study compared HRQoL and ability to work in 3 HER2+ patient cohorts: EBC during adjuvant treatment, EBC after treatment, and metastatic disease (MBC). METHODS: A cross-sectional observational cohort study of 299 female consenting patients with HER2+BC, from 14 UK secondary care centres. Group1 (n=89): receiving targeted HER2 therapy±chemotherapy for EBC; Group2 (n=108): in follow up post-targeted treatment for eBC; Group3 (n=102): MBC on treatment. Data collected between Dec 2016-Mar 2017: HRQoL, demographic and employment status data collected via patient-reported questionnaires (including EQ-5D-5L and Functional Assessment of Cancer Therapy [FACT-B]); clinical data collected from medical records. Inter-group differences were assessed using univariate Analysis of variance (ANOVA) and chi-square tests as appropriate. [NCT03099200]. RESULTS: Table1 shows patient demographics, disease characteristics, employment status, and EQ-5D-5L scores. Group1 and Group2 patients did not differ in overall health utility or visual analogue scale (VAS) scores. However, Group3 patients reported significantly poorer health utility than Group1 (p CONCLUSIONS: HRQoL in patients with EBC was similar whether on or off treatment, and better than those with MBC. HRQoL scores reported on the generic EQ-5D will be compared with those from the disease-specific FACT-B. A smaller proportion of patients with MBC were employed compared to the EBC groups, reflecting the impact of advanced disease. Fewer patients with EBC reported being unable to work than we expected, suggesting these patients maintain function.
