Abstract
Introduction: The cure for early breast cancer (EBC) is increasing over the last decades due to the improvement of diagnosis and therapy. Individualization of cancer treatment in EBC requires constant optimization by implementing current guidelines. The AGO (working group gynecologic oncology) QS-Mamma initiative, a quality assurance program (QS) of the AGO Breast Committee, was introduced to provide insight in guideline adherence in real-world practice in Germany. We evaluated 10 years of QS-Mamma data to identify gaps and trends implementing those guidelines.
Methods: QS-Mamma is a retrospective sample survey providing a representative overview of the treatment landscape of breast cancer in Germany. The last six cohorts were analyzed over a period of 10 years. Across all cohorts, an average of 264 centers documented a total of n = 4,577 patients with EBC.
Results: Testing for BRCA mutations in triple-negative patients increased significantly. Breast conserving surgery has been standard of care since the start of data collection; choice of surgical procedure depends primarily on tumor size and nodal status according to the patient's preference, if possible. Axillary intervention has shifted toward SLNE or targeted axillary procedures in patients with negative preoperative nodal staging. Neoadjuvant systemic therapy in operable EBC is established. Anthracycline administration in the adjuvant setting decreases. We noted an uptake on using platinum-containing CTx in TNBC, corresponding to AGO recommendations. Dual HER2 blockade is established in HER2-positive EBC with increased risk of relapse. Changes in guidelines are reflected in real-world data.
Conclusion: Guideline adherence in breast cancer care is high and new treatments and diagnostic options are implemented promptly. Finally, escalation and de-escalation of treatment depend on individual tumor characteristics resulting in the individual risk of recurrence. Guidelines should be flanked by real-world evidence to ensure and survey their impact.
期刊介绍:
''Breast Care'' is a peer-reviewed scientific journal that covers all aspects of breast biology. Due to its interdisciplinary perspective, it encompasses articles on basic research, prevention, diagnosis, and treatment of malignant diseases of the breast. In addition to presenting current developments in clinical research, the scope of clinical practice is broadened by including articles on relevant legal, financial and economic issues.
