PRIMARY outcome

Timeframe: At 15 days

Population: Per RECIST v1.0 for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the LD of target lesions; Progression (PD),20% increase in the sum of the LD of target lesions,or measurable increase in a non-target lesion,or appearance of new lesions.",

RECIST measurements will be performed on serial MRIs to evaluate the correlation with FDG-PET. The longest diameter (LD) of the target lesions will be measured and reported as the baseline LD. The baseline LD will be used as reference to further characterize the objective tumor response of the measurable dimension of the disease.Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Progression (PD), a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions

SECONDARY outcome

Timeframe: At baseline and after 14 days

Plasma will be collected for measurement of VEGF and soluble VEGFR2 (sVEGFR2) at baseline, after the 14 day Run-in period of pazopanib, after completion of neoadjuvant chemotherapy and approximately every 3 months thereafter until completion of pazopanib maintenance therapy, when indicated. Quantitative enzyme-linked immunosorbent assays (ELISA) for VEGF and sVEGFR2 will be performed on plasma and tumor extracts. Plasma will also be collected for micro RNA at baseline, after the 14 day Run-in period of pazopanib, following neoadjuvant chemotherapy and every 3 months thereafter until completion of pazopanib maintenance therapy, when indicated.
