New PET imaging approach detects almost all lesions in common form of kidney cancer
A new PET imaging approach detected 97.9% of lesions in clear cell renal cell carcinoma (ccRCC), potentially giving clinicians a more complete picture of the location and extent of a patient's disease, according to research presented at the 39th Annual Congress of the European Association of Nuclear Medicine (EANM'26).
A novel PET imaging technique has shown promising results in detecting nearly all lesions in clear cell renal cell carcinoma (ccRCC), a common form of kidney cancer. According to research presented at the 39th Annual Congress of the European Association of Nuclear Medicine, this new approach, targeting carbonic anhydrase IX (CAIX), achieved 97.9% detection of ccRCC lesions, compared to 47.1% with the commonly used ¹⁸F-FDG PET/CT.
The researchers believe that CAIX's high expression in ccRCC, coupled with minimal expression in normal renal tissue, allows for clearer distinction of tumors from healthy tissue. This imaging method could potentially improve clinical decisions, including staging and management, with changes in clinical management or disease stage observed in 30.9% of patients when compared to 5.9% with ¹⁸F-FDG PET/CT.
However, further research is needed to validate the findings in larger studies and across various RCC subtypes.
