Assessed by Common Terminology Criteria for Adverse Events version 4.0. The number of patients experiencing a grade 3 or greater adverse event (AE) regardless of attribution will be reported.

Analysis population: Only patients that received treatment were included in AE analysis

Groups in this outcome

Arm I (Combination Chemotherapy, Atezolizumab)

Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1, and fluorouracil IV as a bolus on day 1, then continuously over 46 hours on days 1-3 of each cycle. Treatment repeats every 14 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive atezolizumab IV over 30-60 minutes on day 1 of each cycle, beginning in cycle 1 or 2. Treatment repeats every 14 days for up to 25 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo CT or MRI every 6 months for the first 2 years, then for years 3-5 or until evidence of relapse, whichever comes first. Patients may also undergo blood sample collection throughout the trial.\> \> Atezolizumab: Given IV\> \> Biospecimen Collection: Undergo blood sample collection\> \> Computed Tomography: Undergo CT\> \> Fluorouracil: Given IV\> \> Leucovorin Calcium: Given IV\> \> Magnetic Resonance Imaging: Undergo MRI\> \> Oxaliplatin: Given IV\> \> Quality-of-Life Assessment: Ancillary studies
