Patient-reported outcome thresholds and their associations with survival, adverse events, and quality of life in a pooled analysis of breast cancer trials.

ABSTRACT: Researchers at the EORTC recently recommended clinical thresholds for the QLQ-C30 to facilitate actionable insights in clinical practice. We evaluate the distribution of these thresholds and associations with outcomes in breast cancer. Data were pooled from two early-stage and six advanced-stage breast cancer trials. EORTC thresholds were applied to available QLQ-C30 data to identify clinically important PRO domains. Associations between the number of clinically important PRO domains at baseline with overall survival (OS), invasive-disease-free survival (IDFS), progression-free survival (PFS), grade ≥3 adverse events (AEs), and serious AEs were evaluated using Cox-regression. Data from 8544 breast cancer patients, of whom 2428 (41%) of the 5893 early-stage and 1486 (56%) of the 2651 advanc
