Zusammenfassung: | Background
Several randomized clinical trials (RCTs) have demonstrated the efficacy of trastuzumab-based adjuvant therapy in HER2-positive breast cancer (BC). However, RCT patients may not invariably be representative of patients routinely seen in clinical practice (CP). To address this issue, we compared the clinical and tumor features of RCT and CP patients with HER2-positive BC.
Patients and methods
From January to December 2012, 650 consecutive patients with HER2-positive early BC, treated in 36 different types of Italian healthcare facilities, were enrolled in this study. Age, treatment, tumor size (T), nodes (N), grade (G), estrogen receptor (ER) and progesterone receptor (PgR) status were prospectively collected in these CP patients. The same data were extracted from the main adjuvant trastuzumab RCTs and pooled using the random-effects model of DerSimonian and Laird. RCT and CP patients were compared by using the Cochran Q statistics.
Results
Versus RCT patients, CP patients were more likely to be older than 50 years (65 vs. 49 %;
