A new PET scan agent shows high accuracy in detecting kidney cancer, especially small tumors, and is now recommended in global guidelines.
TLX250-CDx (Zircaix), an investigational PET imaging agent targeting carbonic anhydrase IX in kidney cancer, has been included in new guidelines from major global nuclear medicine organizations for the first time.
The guidelines highlight its high accuracy in detecting clear cell renal cell carcinoma, with 86% sensitivity, 87% specificity, and 93% positive predictive value in the ZIRCON trial, particularly for small, hard-to-see tumors.
Unlike standard 18F-FDG PET, it offers better image clarity due to lower kidney excretion.
The agent is not yet approved but may accelerate clinical use as a tool for precise diagnosis and personalized treatment planning.
