Trial Information

Avastin/[18-F]-5-fluorouracil PET/CT Imaging Feasibility Project

Inclusion Criteria:

1. Patients must have histologically or cytologically confirmed adenocarcinoma of the

2. Patients must have metastatic disease to the liver with at least one lesion that is
measurable by RECIST criteria within 4 weeks prior to entry of study

3. Patients with a history of colon adenocarcinoma treated by surgical resection who
develop radiological or clinical evidence of metastatic cancer do not require
separate histological or cytological confirmation of metastatic disease unless an
interval of > 5 years has elapsed between the primary surgery and the development of
metastatic disease. Clinicians should consider biopsy of lesions to establish
diagnosis of metastatic colon adenocarcinoma if there is substantial clinical
ambiguity regarding the nature or source of apparent metastases.

4. Patients must have ECOG performance status of 0-2

5. Patients must be >= 18 years of age

6. Laboratory values <= 2 weeks prior to enrollment:

- Absolute Neutrophil Count (ANC) >= 1.5 x 10^9/L (>= 1500/mm^3)

- Platelets (PLT) >= 100 x 10^9/L >= 100,000/mm^3)

- Hemoglobin (Hgb) >= 9 g/dL

- Serum creatinine <= 1.5 ULN

- Serum bilirubin <= 1.5 ULN

- Aspartate aminotransferase (AST/SGOT) and alanine aminotransferase (ALT/SGPT) <=
3.0 x ULN (<= 5 x ULN if liver metastases present). Note: ERCP or percutaneous
stenting may be used to normalize the liver function tests.

- Negative for proteinuria based on dip stick reading OR, if documentation of +1
result for protein on dip stick reading, then total urinary protein <= 500 mg
and measured creatinine clearance (CrCl) >= 50 mL/min from a 24-hour urine

7. Life expectancy >= 12 weeks

8. Ability to give written informed consent according to local guidelines

Exclusion Criteria:

1. Patients receiving prior 5-FU for the treatment of metastatic colorectal
adenocarcinoma will be excluded from enrollment. Previous use of 5-FU for adjuvant
treatment of resected stage II or III colorectal adenocarcinoma will be allowed,
provided the time from last 5-FU administration to enrollment is > 3 months.

2. Prior full field radiotherapy <= 4 weeks or limited field radiotherapy <= 2 weeks
prior to enrollment. Patients must have recovered from all therapy-related
toxicities. The site of previous radiotherapy should have evidence of progressive
disease if this is the only site of disease.

3. Prior biologic or immunotherapy <= 2 weeks prior to registration. Patients must have
recovered from all therapy-related toxicities

4. Prior therapy with anti-VEGF agents

5. Patients with a history of another primary malignancy <= 5 years, with the exception
of inactive basal or squamous cell carcinoma of the skin

6. Concurrent use of other investigational agents and patients who have received
investigational drugs <= 4 weeks prior to enrollment.

7. Female patients who are pregnant or breast feeding, or adults of reproductive
potential not employing an effective method of birth control. Barrier contraceptives
must be used throughout the trial in both sexes. Women of childbearing potential must
have a negative serum pregnancy test 48 hours prior to administration of study

8. Patients unwilling to or unable to comply with the protocol
