Experimental: Treatment (bevacizumab, mFOLFOX7)
Patients receive bevacizumab IV over 30-90 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil IV continuously over 46-48 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. Within 6-8 weeks after treatment, patients undergo surgery.

I. To determine if six cycles of modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX7) plus bevacizumab (Avastin) will yield complete pathologic response (cPR) of 25% or more in the primary tumor of patients with stage II and III rectal cancer.
I. To assess the rate of tumor regression (pathologic stage lower than clinical stage) after 6 cycles of mFOLFOX7 and bevacizumab in the primary rectal cancer.
II. To assess local recurrence rate over 3 years after 6 cycles of mFOLFOX7 and bevacizumab.
I. Correlation of the following marker with response (defined as CPR or down staging):
- Intratumoral Gene expression and germline polymorphism of genes involved in the vascular endothelial growth factor (VEGF) and VEGF independent pathways (VEGF, vascular endothelial growth factor receptor 1 [VEGFR1], VEGFR2, interleukin-8 [IL8], chemokine (C-X-C motif) receptor 2 [CXCR2], intercellular adhesion molecule [ICAM], VEGFR1 and VEGFR2, neuropilin 1 or 2 [NRP1,2], cluster of differentiation [CD] 44, aldehyde dehydrogenase [ALDH], leucine-rich repeats and immunoglobulin-like [LRIG].
- Circulating tumor cells (CTC) and VEGF-factor A (A) on the CTC.
II. Prediction of surgical resection margin by pretreatment magnetic resonance imaging (MRI).
Patients receive bevacizumab intravenously (IV) over 30-90 minutes, oxaliplatin IV over 2 hours, leucovorin calcium IV, and fluorouracil IV continuously over 46-48 hours on day 1. Treatment repeats every 14 days for 6 courses in the absence of disease progression or unacceptable toxicity. Within 6-8 weeks after treatment, patients undergo surgery.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
