Diego Barreiro, Head of Oncological Urology, Hospital Carlos G. Durand, shared on X:
“We should move beyond the Phoenix criterion (PSA nadir + 2) for defining recurrence following prostate radiotherapy.
When using the ‘nadir + 2’ threshold, 40% of patients are found to have metastases upon PSMA-PET imaging.
By adopting ‘nadir + 1’ as the new criterion, we could potentially cure nearly 62% of patients.
What happens if we compare prostatectomy versus radiotherapy for prostate cancer using this new cutoff value?”
