Abstract

Limited data exist on the association of symptom burden, daily activity impairment, and work productivity (WP) in patients with advanced breast cancer. This cross-sectional analysis evaluated baseline patient-reported outcomes (PROs) in patients with locally recurrent or metastatic breast cancer (MBC) receiving first-line hormonal therapy or chemotherapy and/or targeted therapy in the VIRGO observational study. The primary PRO study endpoint, symptom severity and interference score, was measured using the MD Anderson Symptom Inventory (MDASI). Secondary endpoints included Activity Level Scale (ALS), health-related quality of life (HRQOL), and Work Productivity and Activity Impairment Questionnaire (WPAI:SHP) scores. Overall, 152 patients (chemotherapy cohort, 104; hormonal therapy cohort, 48) answered questionnaires. Fatigue, decreased sexual interest, disturbed sleep, emotional distress, and drowsiness were the most common severe symptoms, and were of moderate-to-severe intensity in 38.8%-52.0% of patients. Mean percent daily activity impairment was 30% for study patients, and WP impairment ranged from 20% to 40% across indices in employed patients (. n, 58). Significant positive correlations existed for MDASI severity and interference scores with activity impairment and WP indices (Pearson correlation coefficients [. R]=0.47-0.82; p<0.0001). ALS and overall HRQOL correlated negatively with these indices (. R=-0.41 to-0.60; p≤0.001). After adjustment for potential confounders, MDASI symptom interference and ALS were significant predictors of activity and WP impairment. Our results indicate patients receiving treatment for MBC are symptomatic with significant daily activity and/or WP impairment. Symptom severity and interference, functional status, and overall HRQOL were moderately correlated with perceived work-related ability.
