About
This pilot phase II trial studies how well giving bevacizumab and combination chemotherapy together before surgery works in treating patients with locally advanced esophageal or stomach cancer. 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. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab and combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain after surgery.
Full description
PRIMARY OBJECTIVES:
I. To investigate two-year disease-free survival in patients with resectable esophageal and gastroesophageal (GE) junction cancer treated with perioperative bevacizumab and leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX).
SECONDARY OBJECTIVES:
I. To assess, by pathological examination after surgical resection, complete and partial response to neoadjuvant therapy.
II. To characterize overall and progression free survival. III. To compare baseline and post-chemotherapy/bevacizumab tissues for biomarkers predicting response or resistance to this approach.
IV. To investigate safety in this setting.
OUTLINE:
NEOADJUVANT THERAPY: Patients receive bevacizumab intravenously (IV) over 30-90 minutes on day 1. Patients also receive FOLFOX chemotherapy comprising oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1, and fluorouracil IV continuously over 46 hours on days 1-2. Treatment with bevacizumab repeats every 2 weeks for 4 courses and treatment with FOLFOX repeats every 2 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.
SURGERY: Patients then undergo planned surgical resection 4-6 weeks after 6 courses of chemotherapy and at least 8 weeks since the last dose of bevacizumab.
ADJUVANT THERAPY: Beginning 8-10 weeks after surgery, patients receive bevacizumab IV, oxaliplatin IV, leucovorin calcium IV, and fluorouracil IV as in neoadjuvant therapy. Treatment repeats every 2 weeks for 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 4 months for 1 year, every 6 months for 2 years, and then annually thereafter.

Exclusion criteria
- Patients with prior chemotherapy for any malignant disorder, thoracic radiotherapy or prior surgical resection of an esophageal tumor are ineligible
- Patients with biopsy-proven invasion of the tracheobronchial tree or tracheo-esophageal fistula are ineligible
- Patients with a history of a curatively treated malignancy must be disease-free for at least two years and have a survival prognosis that is greater than five years
- Eligible patients of reproductive potential (both sexes) must agree to use an accepted and effective method of contraceptive during study therapy and for at least 6 months after the completion of bevacizumab; women must not be pregnant or breast-feeding because the study drugs administered may cause harm to an unborn fetus or breastfeeding child; all females of childbearing potential must have a serum pregnancy test to rule out pregnancy within 7 days prior to registration
- Patients with a history of hypertension must measure < 150/90 mmHg and be on a stable regimen of anti-hypertensive therapy; patients with a history of hypertension who have a blood pressure of 150/90 mmHg, or greater are not eligible; patients with a history of hypertension who have a blood pressure of < 150/90 mmHg but are not on a stable regimen of anti-hypertensive therapy, are not eligible
- Any prior history of hypertensive crisis or hypertensive encephalopathy

- Patients with PT (INR) > 1.5 are not eligible; the patient may not be receiving full-dose anticoagulation; prophylactic or full dose anticoagulation are permitted post-resection or for treatment of an intercurrent thrombotic event
- Patients with non-malignant systemic disease (cardiovascular, renal, hepatic, etc.) that would preclude any of the study therapy drugs are not eligible; specifically excluded are the following conditions: current symptomatic arrhythmia, symptomatic peripheral vascular disease

- Distant metastases
- History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to study enrollment
- Known hypersensitivity to any component of bevacizumab
