Postoperative Chemotherapy With or Without Bevacizumab for Patients With Stage II or III Rectal Cancer

Stopped early · Phase 3

Conditions studied: Adenocarcinoma of the Rectum, Stage II Rectal Cancer, Stage III Rectal Cancer

In brief

Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, 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 tumor cells by blocking blood flow to the tumor. Giving more than one drug (combination chemotherapy) together with bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known whether oxaliplatin, leucovorin, and fluorouracil is more effective with or without bevacizumab in treating rectal cancer. This randomized phase III trial is studying combination chemotherapy to see how well it works with or without bevacizumab in treating patients who have had surgery for stage II or stage III rectal cancer.

• Hepatitis B and C negative (for patients with AP > normal) unless previously vaccinated
• Serum creatinine =< 1.5 times ULN

You may not qualify if…

• Pregnant or nursing

• Evidence of tumor outside of the pelvis, including liver metastases, peritoneal seeding, or metastatic inguinal lymphadenopathy
• Concurrent major surgery
• Active bleeding not related to the primary rectal tumor within the past 6 months
• Active inflammatory bowel disease or other serious medical illness which might limit the ability of the patient to receive protocol therapy
• Active gastroduodenal ulcer determined by endoscopy
• Serious or nonhealing wound, skin ulcer, or bone fracture
• Clinically significant peripheral sensory or motor neuropathy >= grade 2
• Nonmalignant systemic disease (e.g., cardiovascular, renal, or hepatic) that would preclude study treatment including, but not limited to, any of the following:
• New York Heart Association class III or IV congestive heart failure
• Concurrent symptomatic arrhythmia
• Transient ischemic attack or cerebrovascular accident
• Arterial thromboembolic event, unstable angina, or myocardial infarction within the past 12 months
• Significant peripheral vascular disease
• Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude study requirements
• Significant traumatic injury within the past 28 days
• Known allergy to platinum compounds
• Prior invasive procedure, including either of the following:
• Major surgical procedure or open biopsy within the past 28 days
• Core biopsy or other minor procedure, except placement of a vascular access device, within the past 7 days
