Plain-language summary
This phase III trial studies how well combination chemotherapy, bevacizumab, and/or atezolizumab work in treating patients with deficient deoxyribonucleic acid (DNA) mismatch repair colorectal cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Chemotherapy drugs, such as fluorouracil, oxaliplatin, and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of the tumor. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy, bevacizumab, and atezolizumab may work better in treating patients with colorectal cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* The patient must have signed and dated an Institutional Review Board (IRB)-approved consent form that conforms to federal and institutional guidelines
* Age \>= 18 years
* Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2
* Diagnosis of metastatic adenocarcinoma of colon or rectum without previous chemotherapy or any other systemic therapy for metastatic colorectal cancer except for one cycle of FOLFOX or capecitabine and oxaliplatin (CAPOX), either with or without bevacizumab prior to enrollment. Upon enrollment, the preceding single cycle of FOLFOX or FOLFOX + bevacizumab, if the patient received one, will not count towards patients' assessments per protocol. Cycle 1 day 1 (C1D1) of atezolizumab or C1D1 of mFOLFOX6/bevacizumab + atezolizumab will correspond to the first day the patient received therapy on trial
* Tumor determined to be mismatch-repair deficient (dMMR) by Clinical Laboratory Improvement Act (CLIA)-certified immunohistochemical (IHC) assay with a panel of all four IHC markers, including MLH1, MSH2, PMS2, and MSH6; alternatively, MSI-H diagnosed by polymerase chain reaction (PCR)-based assessment of microsatellite alterations (either Bethesda markers or Pentaplex panel) or by next-generation sequencing (NGS) are eligible
* Documentation by PET/CT scan, CT scan, or MRI that the patient has measurable metastatic disease per RECIST 1.1
* No immediate need for surgical intervention for the primary tumor or palliative …
