Oxaliplatin, Leucovorin Calcium, and Fluorouracil With or Without Bevacizumab in Treating Patients Who Have Undergone Surgery for Stage II Colon Cancer

Not Recruiting

Trial ID: NCT00217737


This randomized phase III trial studies oxaliplatin, leucovorin calcium, fluorouracil, and bevacizumab to see how well they work compared to oxaliplatin, leucovorin calcium, and fluorouracil in treating patients who have undergone surgery for stage II colon cancer. Drugs used in chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, 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. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving combination chemotherapy together with bevacizumab is more effective than combination chemotherapy alone in treating colon cancer.

Inclusion Criteria:


   - The distal extent of the tumor must be >= 12 cm from the anal verge on endoscopy; if
   this distance was not confirmed on endoscopy pre-operatively, then the distal extent
   of the tumor must be >= 12 cm from the anal verge as determined by surgical
   examination; colonoscopy should be performed postoperatively for those unable to have
   a preoperative colonoscopy to guarantee there are no synchronous lesions; (if tumor is
   located beyond sigmoid colon and centimeter distance unavailable, include anatomic
   region of colon, e.g. right colon, transverse colon, hepatic flexure descending colon,
   cecum etc.)

   - Patients must have paraffin-embedded tumor specimen available for evaluation of
   microsatellite instability and loss of heterozygosity at 18q, to determine high risk
   versus low risk

      - High-risk patients will be randomized to treatment Arms A or B

      - Low-risk patients will be registered to Arm C for observation

         - NOTE: Every effort should be made to submit blocks (tumor and normal mucosa)
         to the Principal Coordinates Analysis (PCO) immediately; blocks CANNOT be
         accepted after day 50 (post surgery) in order to allow for molecular

         - Specific laboratory requirements for Step 2 must be obtained within 2 weeks
         prior to Step 2 randomization

   criteria below:

      - Stage II adenocarcinoma (pT3/pT4a/pT4b pN0 M0 according to the definitions of the
      American Joint Committee on Cancer, 7th Edition, 2010): the tumor invades through
      the muscularis propria into pericolic tissues (pT3), penetrates to the surface of
      the visceral peritoneum (pT4a), or directly invades other organs or structures
      (pT4b); patients with mesenteric tumor deposits or satellites without
      identifiable residual lymph node in the absence of lymph node involvement are now
      designated pN1c, rather than pT3; patients with such tumor deposits are not
      eligible for E5202; patients must have had a complete resection (R0 resection)

   - Patients must have >= 8 lymph nodes evaluated and reported

   - Patients must not have presented with clinical complete obstruction or perforation of
   the bowel

   patients who meet any of the following conditions:

      - Non-melanoma skin cancer, in situ cervical cancer, or breast cancer in situ

      - Prior malignancy completely excised or removed and patient has been continuously
      disease free for > 5 years

      - Patients with completely excised or removed breast cancer and disease free > 5
      years, regardless of the continuation of hormonal therapy

      - Patients with previous radiation therapy (RT) to the pelvic region will be

   - Within 2 weeks prior to randomization, postoperative absolute granulocyte count (AGC)
   must be >= 1500/mm^3 (or < 1500/mm^3, if in the opinion of the investigator, this

   patient has a chronic grade 1 bilirubin elevation due to Gilbert's disease or similar
   syndrome due to slow conjugation of bilirubin
