Brief Summary
The purpose of this study is to see if an antibody (cG250) attached to a radioactive substance (Iodine-124) safely detects clear cell renal cancer in patients with kidney tumors scheduled for surgery.

Outcome Measures
Primary Outcomes (1)
Positive Predictive Value (PPV) of 124I-cG250 Based on Positron-Emission Tomography/Computed Tomography (PET/CT) Imaging in the Detection of Clear Cell Renal Cell Carcinoma (RCC) Compared to Pathology of Tumor Mass at Surgical Resection.
Patients were listed as PET-positive based on a tumor to nontumor radioactive uptake ratio of \> 3 and PET-negative if less than or equal to 3. The resected renal mass (tumor) was subjected to pathological evaluation, and a diagnosis of clear cell RCC or non-clear cell RCC was made. PPV is the proportion of patients with a positive PET scan who actually have the disease based on pathology. Patients who have a positive PET scan on imaging and clear cell RCC on pathology will be considered true-positives. Patients who have negative PET scans on imaging and non-clear cell RCC on pathology will be considered true-negatives. Patients with positive PET scans on imaging and non-clear cell RCC on pathology will be considered false positives and those with clear cell RCC on pathology but negative PET scans on imaging will be considered false negatives.

Secondary Outcomes (3)
Negative Predictive Value (NPV) of 124I-cG250 Based on Positron-Emission Tomography/Computed Tomography (PET/CT) Imaging in the Detection of Clear Cell Renal Cell Carcinoma (RCC) Compared to Pathology of Tumor Mass at Surgical Resection.

Study Arms (1)
124I-cG250
EXPERIMENTALPatients who were scheduled for surgical resection of renal masses received a single intravenous (IV) dose of 10 mg of 5 milliCurie (mCi) /10 mg 124I-cG250. Patients underwent Positron-Emission Tomography/Computed Tomography (PET/CT) imaging of the whole body on at least 2 occasions: once following injection and once immediately prior to surgical resection. Patients were scheduled for surgical resection of their renal masses on day 8.

Eligibility Criteria
You may qualify if:
- Presence of a renal mass.
- Scheduled for surgical resection of renal mass.
- Expected survival of at least 3 months.
- Karnofsky performance scale ≥70.
- The following laboratory results should be within the following limits within the last 4 weeks prior to study day 1:
- Absolute neutrophil count (ANC) ≥ 1.5 x 10E9/L

- Pregnancy Test to be performed on female patients of childbearing potential within 24-48 hours before administration of radioactive material.
- Recovered from toxicity of any prior therapy.
- Able and willing to give valid written informed consent.
You may not qualify if:

- New York Heart Association Class III/IV cardiac disease.
- History of autoimmune hepatitis.
- Chemotherapy, radiotherapy, or immunotherapy within 4 weeks prior to the first cG250 dose.

- Lack of availability for immunological and clinical follow-up assessments.
- Participation in any other clinical trial involving another investigational agent within 4 weeks prior to enrollment.
- Women who are pregnant or breastfeeding.
- Allergy to iodine.
