Neoadjuvant bevacizumab and anthracycline-taxane-based chemotherapy in 678 triple-negative primary breast cancers; results from the geparquinto study (GBG 44).
Abstract Background We evaluated the pathological complete response (pCR) rate after neoadjuvant epirubicin, (E) cyclophosphamide (C) and docetaxel containing chemotherapy with and without the addition of bevacizumab in patients with triple-negative breast cancer (TNBC). Patients and methods Patients with untreated cT1c-4d TNBC represented a stratified subset of the 1948 participants of the HER2-negative part of the GeparQuinto trial. Patients were randomized to receive four cycles EC (90/600 mg/m2; q3w) followed by four cycles docetaxel (100 mg/m2; q3w) each with or without bevacizumab (15 mg/kg; q3w) added to chemotherapy. Results TNBC patients were randomized to chemotherapy without (n =…
Analysis according to prognostic factors in patients (pts) treated with first-line bevacizumab (BEV) combined with paclitaxel (PAC) for HER2-negative metastatic breast cancer (mBC) in a routine oncology practice study.
1077 Background: 1st-line BEV combined with weekly PAC significantly improves progression-free survival (PFS) and response rate (RR) vs PAC alone in HER2-negative mBC, as shown in E2100. We analyzed data from a German routine oncology practice study of 1st-line BEV–PAC according to prognostic factors. Methods: Pts who had received no prior chemotherapy for mBC received BEV–PAC according to the European label. Efficacy and safety were documented for up to 1 y (or until progression, death, or BEV discontinuation if earlier) with additional long-term follow-up. Efficacy was analyzed in clinically important subgroups. Results: Efficacy data were available for 818 pts. The median duration of fo…
