Weekly administration of bendamustine as salvage therapy in metastatic breast cancer: final results of a phase II study.

Single-agent bendamustine has shown promise in the treatment of metastatic breast cancer. As toxicity was low after weekly administration of this drug in other solid tumors, the present double-center phase II trial was conducted to evaluate the efficacy and toxicity of weekly bendamustine as salvage treatment in metastatic breast cancer. A total of 34 patients with anthracycline (88%) and/or taxane (71%) pretreated for metastatic breast cancer received 60 mg/m bendamustine on day 1, 8 and 15 every 28 days for six cycles.

Doxorubicin/pemetrexed followed by docetaxel versus doxorubicin/ cyclophosphamide followed by docetaxel as neoadjuvant treatment for early-stage breast cancer: a randomized phase II trial.

Background: Microarray gene expression profiling has indicated that complex molecular gene expression signatures might be predictive of outcome after systemic treatment for early breast cancer. Neoadjuvant systemic therapy (NST) with its assessment of pathologic complete response (pCR), so far the best surrogate parameter for cure, provides a unique opportunity to rapidly identify such molecular predictors.

Patients And Methods: Currently, an international, randomized phase II study of 2 sequential regimens as NST is being conducted in patients with primary invasive breast cancer T2-4a-c N0-2 M0.

Safety and pharmacokinetics of bivatuzumab mertansine in patients with CD44v6-positive metastatic breast cancer: final results of a phase I study.

The purpose of this study was to investigate the safety, pharmacokinetics and preliminary efficacy of bivatuzumab mertansine in patients with CD44v6-positive metastatic breast cancer. Anthracycline and taxane-pretreated patients with metastatic breast cancer that expressed CD44v6 received one single infusion of bivatuzumab mertansine and were observed for 21 days within one treatment course. Starting dose was 25 mg/m, while dose was escalated by increments of 25 mg/m.

Dose-dense primary systemic chemotherapy with gemcitabine plus epirubicin sequentially followed by docetaxel for early breast cancer: final results of a phase I/II trial.

We recruited 50 patients with T2-4 N0-2 M0 primary breast cancer into a phase I/II study to define the maximum tolerated dose (MTD), efficacy and tolerability of preoperative gemcitabine (1250 mg/m fixed dose) plus epirubicin (doses escalated from 90 mg/m) for 5 cycles followed by 4 cycles of docetaxel (scheduled fixed dose 100 mg/m) given on day 1 every 2 weeks (q2w) with pegfilgrastim support. The MTD for epirubicin was 100 mg/m, but the docetaxel dose had to be reduced to 80 mg/m. Dose-limiting toxicities included fatigue, stomatitis, diarrhea and dyspnea (all grade 3) during gemcitabine plus epirubicin, and fatigue (grade 3) and allergic reaction (grade 4) during docetaxel treatment, respectively.
