To define the capability of DCE-CT as an imaging biomarker for monitoring treatment responses to anti-angiogenic therapy.
- Early changes in microvasculature functional imaging biomarkers measured by DCE-CT with response by RECIST criteria.
- Microvascular imaging biomarkers with plasma concentration of plasma sunitinib concentration;
- Progression-free survival with microvascular imaging biomarkers.
Define reproducibility of:
- Microvascular parameters through CT standard operating procedure (SOP) combining CT RECIST assessment with DCE-CT.
- DCE-CT derived microvasculature related imaging biomarkers in the assessment of sunitinib treatment of RCC.
- Assess imaging biomarkers variability across two different platforms (64-& 320-slice CT).

Evaluation of imaging biomarkers (BOLD-MRI and FLT-PET) for accessing/monitoring treatment response.
- Organize the infrastructure required to overcome the logistical challenges of integrating BOLD MRI and FLT-PET into clinical practice;
- Correlate BOLD MRI and FLT-PET and tumour markers with tumour histology pre-chemotherapy, with pathologic tumour response observed at mastectomy;
- Establish multi-centre SOPs and Q/A process for BOLD MRI and FLT-PET.

To improve the care of women with HER2-positive metastatic breast cancer (MBC) by using 111In-pertuzumab imaging to predict who will respond to treatment with trastuzumab.
- Study the safety, pharmacokinetics, radiation dosimetry, and tumour and normal tissue localization properties of 111In-pertuzumab in patients with HER2-positive MBC who are beginning trastuzumab therapy combined with chemotherapy;
- Examine whether SPECT imaging with 111In-pertuzumab can predict a clinical response to trastuzumab in patients with HER2-positive MBC who are beginning trastuzumab therapy combined with chemotherapy;
- In patients with HER2-positive MBC to conduct correlative biomarker studies that provide information on the binding of 111In-PmAb to tumour and to explore whether certain biomarkers in the primary tumour are associated with clinical response to TmAb.
