| 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 or lung 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.
16) For lung lesions: a. Lung lesions must not be cavitating. b. The index lesion must be more than 1 cm cranial to the dome of the diaphragm. c. Paramediastinal lesions should be avoided. d. Pleural lesions are acceptable if they meet all other criteria. e. Lymphatic tissue is not to be used as target lesions in this protocol |
