OBJECTIVE: Although bevacizumab and trastuzumab have been widely added to the standard regimen for metastatic breast cancer, the clinical outcomes remain controversial. The purpose of this study was to conduct meta-analysis to verify the clinical efficacy and safety of docetaxel and bevacizumab with or without trastuzumab as first-line treatment for patients with metastatic breast cancer (MBC).
MATERIALS AND METHODS: All available literature of clinical trials about docetaxel, bevacizumab, trastuzumab and metastatic breast cancer was pooled from PubMed, Embase and Cochrane library database. The meta-analysis combined the progression free survival (PFS), overall response rate (ORR) and incidence of all grades adverse events in MBC patients.
RESULTS: Seven clinical trials were included by two reviewers. Docetaxel and bevacizumab with trastuzumab show the pooled PFS was 16.53 months (95% CI: 13.95-19.11 months), the pooled ORR was 0.75 (95% CI: 0.69-0.80) in HER2-positive MBC patients. Docetaxel and bevacizumab show that the pooled PFS was 8.49 months (95% CI: 7.80-9.18 months), the pooled ORR was 0.51(95% CI: 0.47-0.55) in HER2-negative MBC patients.
CONCLUSIONS: Both for patients with HER2-positive and negative metastatic breast cancer, docetaxel and bevacizumab with or without trastuzumab as first-line treatment resulted in long survival, especially in terms of progression-free survival. Although the overall response rates are also significantly improved, it is still controversial based on the current evidence.
