Abstract
Purpose
Most clear cell renal cell carcinoma (ccRCC) overexpresses carbonic anhydrase IX (CAIX). [68Ga]Ga-NY104 is a small-molecule PET agent selectively targeting CAIX. This study aims to assess the efficacy of [68Ga]Ga-NY104 PET/CT to identify ccRCC.
Materials and methods
Participants were prospectively recruited in the study (ClinicalTrials.gov: NCT05902377). They were further divided into two groups: group 1, patients with primary renal mass who were scheduled for surgery, group 2, patients with suspected/confirmed metastatic ccRCC. All patients underwent [68Ga]Ga-NY104 PET/CT.
Results
A total of 47 patients (mean age, 58.8 years ± 13.5, 34 men) were recruited, including 20 patients in group 1 and 27 patients in group 2. The patient-level sensitivity, specificity, and accuracy of [68Ga]Ga-NY104 PET scan was 62%, 33%, 58% for group 1 and 95%, 100%, 96% for group 2. [68Ga]Ga-NY104 PET identified additional 26 disease regions in 67% (14/21) of patients that were previously unknown. The tumor uptake was correlated with immunohistochemical staining results.
Conclusions
[68Ga]Ga-NY104 PET/CT has a high diagnostic efficacy for patients with metastatic ccRCC, while it might be of limited value in the diagnosis of primary ccRCC.
