Purpose
The purpose of this research study is to test the safety and of adding bevacizumab to the established regimen of vincristine, oral irinotecan, and temozolomide (VOIT) and see what effects it has in pediatric patients with relapsed or refractory solid tumors.

Detailed Description:
A recent Children's Oncology Group study evaluated the 3-drug combination of vincristine, oral irinotecan, and temozolomide (VOIT), and found it to be safe and tolerable in pediatric patients. This VOIT regimen may be useful for a variety of childhood cancers.
Additional data suggests that the beneficial effects of irinotecan can be improved by giving it with bevacizumab. Bevacizumab is a monoclonal antibody that works against a protein called "vascular endothelial growth factor" (VEGF). In cancer treatment, it is used to reduce tumor growth by blocking the formation of new blood vessels.
All of the drugs used in this study have been approved by the Food and Drug Administration (FDA) for use in adults with certain cancer types. However, the combination of drugs in this study is considered experimental because the FDA has not approved them to be used together.
Each drug has been given by itself to children before, and the combination of temozolomide, irinotecan, and vincristine has been given to children in more than one clinical trial. This is the first study in which all four of the drugs (vincristine, oral irinotecan, temozolomide, and bevacizumab) will be given together to children.
Up to 20 pediatric patients will receive therapy. The previously established bevacizumab dose of 15 mg/kg will be administered by intravenous infusion on day 1 at the start of every 3-week course. Intravenous vincristine will be given on day 1, oral irinotecan on days 1-5, and oral temozolomide on days 1-5. Courses will be repeated as frequently as every three weeks in patients who do not have evidence of disease progression and who have adequate recovery from previous courses. Cephalosporin antibiotics will be used to reduce irinotecan-associated diarrhea.
Patients will be monitored on the study for toxicity and response for up to 6 courses.

Inclusion Criteria:
- Between 1 and 30 years of age, inclusive, at the time of study entry
- Histologic verification of a solid tumor or CNS tumor at either original diagnosis or relapse. Exceptions to the requirement for biopsy include patients with primary brainstem or optic pathway tumors.
- Current disease state must be one for which there is no known curative therapy or therapy proven to prolong survival with an acceptable quality of life.

- Require IV antibiotics at time of enrollment, or who are currently receiving treatment for Clostridium difficile infection.
- Must not have been previously diagnosed with a deep venous or arterial thrombosis (including pulmonary embolism), and must not have a known thrombophilic condition.
- Experienced arterial thromboembolic events, including transient ischemic attacks or cerebrovascular accidents, within the last year. Must not have a history of myocardial infarction, severe or unstable angina, or clinically significant peripheral vascular disease.
