Impact of loss-of-function alterations on the response to PSMA radioligand therapy in metastatic castration-resistant prostate cancer patients.

PSMA-targeting radioligand therapy (PSMA-RLT) has shown promise in metastatic castration-resistant prostate cancer (mCRPC), particularly in PSMA-avid tumours. However, predicting response remains challenging. Preclinical data suggests aberrant p53-signalling as a predictor of poor response.
