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.

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.
