RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of colon cancer by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with bevacizumab works in treating patients with stage IV colon cancer that cannot be removed by surgery.
Further Study Information
- Determine the rate of major morbidity in patients with unresectable stage IV colon cancer and a synchronous asymptomatic primary tumor treated with fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX6) in combination with bevacizumab without resection of the primary tumor.
- Determine the rate of specific events related to the intact primary tumor requiring hospitalization or a major intervention but not requiring surgery.
- Determine the rate of ≥ grade 3 toxicity as defined by the Common Terminology Criteria for Adverse Events version 3.0 (CTCAE v3.0) that is related to study therapy prior to disease progression.
- Determine overall survival of patients treated with this regimen.
OUTLINE: This is a multicenter study.
Patients receive bevacizumab IV over 30-90 minutes, oxaliplatin IV given concurrently with leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV continuously over 46 hours on days 1 and 2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for 5 years after study entry.
PROJECTED ACCRUAL: A total of 90 patients will be accrued for this study.
- Histologically or cytologically confirmed adenocarcinoma of the colon
- No histological findings other than adenocarcinoma of the colon
- If the primary colon tumor and the metastatic lesions have been identified at the same time and it is not possible to biopsy the colonic lesion, the patient will be eligible without histologic confirmation of the primary cancer of the colon as long as other radiographic studies or scans document the characteristics of a colon cancer AND the biopsy of a metastatic site confirms diagnosis of adenocarcinoma suggestive of a primary tumor of the colon
- Unresected primary tumor of the colon AND radiographically confirmed metastatic colon cancer (single or multiple sites of metastases) that are not considered surgically resectable for cure by chest imaging and CT scan or MRI of the abdomen within the past 4 weeks and by endoscopy within the past 8 weeks
- Asymptomatic primary tumor
- No obstruction, perforation, or active bleeding requiring transfusion
- Distal extent of the tumor must be ≥ 12 cm from the anal verge on endoscopy
- Not a candidate for curative surgical resection of all metastatic and colon primary tumors

- Absolute neutrophil count ≥ 1200/mm³
- Platelet count ≥ 100,000/mm³
- Hemoglobin ≥ 9 g/dL
- Aspartate aminotransferase (AST) ≤ 2.5 times upper limit of normal (ULN) (≤ 5.0 times ULN if liver metastases are present)
- Alkaline phosphatase ≤ 3.0 times ULN (≤ 5.0 times ULN if liver metastases are present)
- Bilirubin ≤ 1.5 times ULN (≤ 2.0 times ULN if liver metastases are present)
- Creatinine < 1.8 mg/dL
- Urine dipstick indicating 0-1+ protein
- If dipstick reading is ≥ 2+, a 24-hour urine collection must demonstrate < 1 g of protein
- Prothrombin Time and International Normalized Ratio (PT/INR) ≤ 1.5 unless the patient is on therapeutic doses of warfarin, in which case the following criteria must be met:
- Patient must have an in-range INR (between 2 and 3) on a stable dose of warfarin
- Patient must not have active bleeding or a pathologic condition that is associated with a high risk of bleeding
- Patients with a history of non-colorectal malignancies must be disease free for ≥ 5 years prior to study entry and be deemed at low risk for recurrence
- Patients with the following cancers are eligible if diagnosed and treated within the past 5 years:
- Carcinoma in situ of the colon
- Melanoma in situ
- Basal cell or squamous cell carcinoma of the skin
- Carcinoma in situ of the cervix
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use effective contraception during and for 3 months after the completion of study therapy
- No uncontrolled blood pressure (BP), defined as BP > 150/100 mm Hg
- No nonmalignant systemic disease that would preclude any of the study therapy drugs, compromise the safety of the patient, or inhibit the patient's ability to participate in the study, including any of the following:
- New York Heart Association class III or IV cardiac disease
- Myocardial infarction within the past 6 months
- Unstable angina within the past 6 months
- Symptomatic arrhythmia
- No transient ischemic attack or cerebrovascular accident within the past 6 months
- No symptomatic peripheral vascular ischemia within the past 6 months
- No arterial thrombotic event within the past 6 months
- No gastroduodenal ulcer(s) determined by endoscopy to be active
- No gastrointestinal perforation within the past 12 months
- No serious or nonhealing wound, skin ulcer, or bone fracture
- No significant traumatic injury within the past 28 days
- No significant episodes of acute bleeding requiring blood transfusion within the past 6 months
- No clinically significant (≥ grade 2) peripheral neuropathy (neurosensory or neuromotor toxicity)
- No pulmonary fibrosis or interstitial pneumonitis by chest x-ray
- No psychiatric or addictive disorders or other conditions that would preclude the patient from meeting study requirements
