研究概览
简要总结
This is a multicenter Phase III study to demonstrate the diagnostic utility of 124I-cG250 PET/CT pre-surgical imaging in patients with operable renal masses.
详细描述
A preoperative 124I-cG250 PET scan may distinguish between clear cell and non-clear cell renal carcinoma in patients with renal masses. Studies of imaging characteristics of 124I by a variety of PET cameras, quantification of tumor uptake of 124I-labeled antibody and correlation with biopsy measurement of tumor and normal tissue have met with encouraging results. As clear cell renal cancers are associated with an aggressive phenotype their a priori determination may help guide appropriate surgical/therapeutic management.

研究组 & 干预措施
124-Iodine-cG250 (124I-cG250)
Single arm study, comparing 124I cG250 PET/CT and CT. Each patient underwent a PET/CT and CT scan days (+/-2days) after receipt of 124I cG250.

124-Iodine-cG250 (124I-cG250)

结局指标
主要结局
Sensitivity and Specificity of 124I-cG250 PET/CT Versus Diagnostic CT.
时间窗: 6 months
Average estimate of three independent, blinded central readers per imaging modality on the proportion of participants that were correctly identified on the 124I-cG250 PET/CT Images of having (sensitivity) or not having (specificity) clear cell renal carcinoma (ccRCC) compared to CT images. Histopathology provided the standard-of-truth because it is the only definitive method for accurately identifying ccRCC.
次要结局
- Accuracy of 124I-cG250 PET/CT Imaging Versus Diagnostic CT Imaging(6 months)
- Positive Predictive Value (PPV)(6 months)
- Negative Predictive Value (NPV)(6 months)
