General Information



Disease Group:	Liver	Supported By:	N/A

Phase of Study:	N/A	Return Visit:	Each subject will need to return once to be scanned a second time between days 2-7.

Treatment Agents:	None	Home Care:	N/A

Treatment Loc:	Only at MDACC

Estimated Length of Stay in Houston:	N/A


Description/ Intervention:	The goal of this clinical research study is to find out if blood flow measurements to tumors can be repeated identically on two separate occasions using dynamic contrast enhanced (dce) CT.

Study Objectives / Outcomes

This pilot project will collect test-retest dceMRI and dceCT data in a setting relevant to Phase I oncology clinical trials. The data will be used to support the definition of a minimum magnitude of treatment-induced changes that can be considered an objective physiological vascular response. This information is useful for establishing proof of activity for angiogenesis inhibitors, a primary target for development of anti-cancer drugs.

The specific objective of this Companion Protocol is to enable a comparative and more comprehensive evaluation of reproducibility of perfusion parameters derived from dceCT, in patients with liver tumors already intended to be enrolled in Protocol 2003-0885, who will be undergoing dceMRI under that protocol.

Enrollment Eligibility

If you do not meet the enrollment eligibility, there may be other treatment options for you. Please Contact the Referral Office for more information.

Inclusion Criteria:

1) Subjects must be at least 18 years old.

2) Subjects must have an ECOG performance score of 0-2.

3) Subjects must have adequate organ function as determined by reviewing medical records for the following criteria a. Bone marrow function (within 30 days of study day 1): 1. Absolute neutrophil count (ANC) > or = 1500 cells/mm^3 2. Platelets > or = 100,000 cells/mm^3 b. Renal function (within 14 days of study day 1): 1. Serum creatinine < or = 1.5 mg/dL or a calculated creatinine clearance of > or = 60 ml/min c. Liver function (within 30 days of study day 1): 1. Bilirubin < or = 1.5 mg/dL 2. AST (SGOT) and/or ALT (SGPT) < or = 5X ULN (upper limit of normal range)

4) Subjects must be diagnosed with primary liver carcinomas or sarcomas, or metastases to these sites.

5) Index lesion selection criteria: Eligible subjects must have at least one primary or metastatic lung/liver malignancy

6) Index lesion selection criteria: Must have at least one lesion located in the lung/liver that is greater than 3cm, and less than 7 cm, in transaxial plane.

7) Index lesion selection criteria: Lesions must be well-demarcated.

8) Index lesion selection criteria: The index lesion should demonstrate visible contrast enhancement on the most recent CT or MRI scan (i.e. not cysts).

9) Index lesion selection criteria: When there are multiple lesions, one lesion should be chosen as the index lesion. Other tumors in the scan volume should be considered of lesser importance.

10) Index lesion selection criteria: The index lesion should be the most enhancing tumor which meets all other criteria.

11) Index lesion selection criteria: The imaging acquisition volume should be centered on the index lesion.

12) Index lesion selection criteria: When possible, the index lesion should be fully encompassed by the imaging acquisition volume.

13) Index lesion selection criteria: Index lesions should be chosen to avoid motion, cardiac pulsation, and beam hardening artifact, particularly from vascular structures, extending into the tumor.

14) Index lesion selection criteria: The volume of interest defined in the baseline study should be used for subsequent studies.

15) For liver lesions: a. Liver lesions must be solid masses, and show no radiographic signs of calcification. 1 If not documented in medical records, these tests will be performed at screening visit. b. For liver lesions, the primary target lesion should be more than 1 cm from the diaphragm. c. Less that 60% of liver should be involved by tumor.

Exclusion Criteria:

1) Chemotherapy/ biologic therapy/ endocrine therapy: Subjects may have received prior standard or investigational therapies for their primary disease, if discontinued for at least 4 weeks prior to start of study treatment.

2) Radiotherapy: Subjects may have received prior radiotherapy, if discontinued for at least 4 weeks prior to start of study treatment, and if not applied to the liver/lung index lesions being evaluated in this study.

3) Surgery: Subjects must have not received surgery for at least 30 days prior to day 1 on this study.

4) For liver lesions: Subjects with portal vein occlusion or ascites that requires regularly scheduled paracentesis.

5) Subjects with a known history of allergic reaction to iodine, iodinated contrast agent, and/or gadolinium.

6) Subjects with a previously known active infection, such as HIV, hepatitis B, or hepatitis C (no screening for seroconversion required).

7) Subjects with any mental disorder (e.g. hepatic encephalopathy) that would limit the understanding or rendering of informed consent and/or compromise compliance with the requirements of this protocol.

8) Female subjects who are pregnant or lactating.

9) Female subjects of childbearing potential unless they have a negative serum or urine pregnancy test within 3 days prior to start of study treatment.
