There is one clinical trial.
Metastatic Breast cancer (MBC) patients from ten Italian Divisions of Medical Oncology, with histologically confirmed HER2-negative MBC, treated with a first-line therapy including bevacizumab 10 mg/m2 i.v. on days 1 and 15 combined with first-line paclitaxel 90 mg/m2 i.v. on days 1,8 and 15, every 4 weeks, will be enrolled for the present pharmacogenetic study. MBC patients treated with first-line chemotherapy including paclitaxel without bevacizumab will be also enrolled as control group.
Prospective Evaluation of VEGFR-2 rs11133360/IL-8 rs4073 Genetic Interaction in Metastatic Breast Cancer Patients Treated With Paclitaxel and Bevacizumab vs. Chemotherapy Alone (BEVAPROS).
Statistical analysis: The first aim of this prospective analysis will be evaluate the possible role of VEGFR-2 rs11133360/IL-8 rs4073 polymorphism genetic interaction to predict the bevacizumab response in terms of PFS.
Description: progression free survival in an unselected population of metastatic breast cancer patients treated with first-line paclitaxel and bevacizumab or with chemotherapy alone, assessed through the multifactor dimensionality reduction methodology (genetic interaction analysis)
Measure: Progression free survival Time: 24 monthsDescription: overall survival in an unselected population of metastatic breast cancer patients treated with first-line paclitaxel and bevacizumab or with chemotherapy alone, assessed through the multifactor dimensionality reduction methodology (genetic interaction analysis)
Measure: Overall survival Time: 24 months
