Comparative Effectiveness of Palliative Chemotherapy in Metastatic Breast Cancer: A Real-World Evidence Analysis.

CONCLUSIONS: The frequency of combination COT use, particularly in first-line, warrants further research given published guideline recommendations. The observed TNT difference favoring single-agent treatment in later lines supports guideline recommendations. Variance between single-agent preference and observed TNT was noteworthy. IMPLICATIONS FOR PRACTICE: Although published data from evidence- and consensus-based guidelines recommend single-agent over combination chemotherapy, the extensive list of agents available for use and a gap in the comparative effectiveness research of these agents have resulted in significant variances in patterns of care. The aim of this study was to assess real-world treatment patterns and their effectiveness during palliative therapy of metastatic breast cancer. The objective was to understand when and how chemotherapy-only treatment is used in metastatic breast cancer and whether comparative effectiveness analysis supports the observed patterns of care.
