N2 - Background: Patient-reported outcomes (PROs) are captured in validated tools to provide the patients’ perspective and voice on their physical, social, emotional, functional, and cognitive abilities. Pre-treatment PROs have shown prognostic importance in other cancer types, however, the prognostic value of PROs in breast cancer has been minimally explored. Methods: In a pooled analysis of contemporary clinical trial IPD from patients with breast cancer, cox-proportional hazard analysis and binary logistic regression was used to assess the association between potential predictors with overall survival (OS) and adverse event (grade ≥ 3) outcomes, respectively. PROs were recorded using the EORTC QLQ-C30 version 3.0 questionnaire in the pooled cohort. Statistical significance was set at a threshold of PResults: Within data available, the EORTC QLQ-C30 version 3.0 questionnaire was used in a pooled cohort of 8,544 patients across 8 clinicals trials. In the pooled cohort, the association between PROs and outcomes was best described by a linear association. Patient-reported physical functioning, appetite loss, and pain were significantly associated with OS. On forward-inclusion, only physical functioning remained within the OS prognostic model. Except for patient-reported financial difficulties, all PRO domains were significantly associated with grade ≥ 3 adverse events. On forward-inclusion, physical functioning, pain, and constipation all remained statistically significant. Conclusions: Within large high-quality IPD, pre-treatment PROs demonstrated significant prognostic relationships with therapeutic outcomes in patients with breast cancer initiating contemporary anticancer treatments. Patient-reported physical functioning was found to be the most prognostic PRO domain for OS, while patient-reported physical functioning, pain, and constipation were retained in a multivariable model prognostic of grade ≥ 3 adverse events.
