Primary Outcome Measures:
  • Comparison between VEGF haplotype and median overall survival (OS) and grade 3/4 hypertension (HTN) [ Designated as safety issue: No ]
  • Comparison between candidate SNP genotype and OS and HTN [ Designated as safety issue: No ]
  • Comparison between VEGF amplification/deletion and median OS [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Comparison between VEGF amplification/deletion and VEGF expression [ Designated as safety issue: No ]

Estimated Enrollment: 363
Study Start Date: April 2010
Estimated Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Detailed Description:



  • To demonstrate that vascular endothelial growth factor-A (VEGFA) haplotypes that are associated with an increased VEGFA expression will predict superior outcome for patients with metastatic breast cancer receiving bevacizumab in ECOG-E2100 (but not for the control arm).
  • To demonstrate that candidate single nucleotide polymorphisms (SNPs) will further improve the predictive capacity of outcome (efficacy and toxicity) in patients enrolled in ECOG-E2100.
  • To demonstrate that tumor VEGFA amplification or borderline amplification (estimated 14% frequency) will predict superior outcome for patients with metastatic breast cancer receiving bevacizumab on ECOG-E2100 whereas those with VEGFA deletion (estimated 11% frequency) will predict inferior outcome.
  • To demonstrate that VEGFA amplification/deletion will not predict outcome in the control arm of ECOG-E2100.


  • To demonstrate that tumor VEGFA amplification will predict increased protein expression as ascertained by IHC.
  • To demonstrate that a combined algorithm calculated from tumor-specific variability (VEGFA amplification/deletion) and host-specific variability (SNPs) will optimally predict outcome (efficacy) with bevacizumab in patients enrolled on ECOG-E2100.

OUTLINE: This is a multicenter study.

Previously collected tumor-derived DNA is analyzed for VEGFA amplification/deletion and haplotype as biomarkers for outcome after bevacizumab treatment. Gene expression, polymorphism, protein expression analysis, and IHC are performed on the samples.
