Serum prostate-specific antigen (PSA) is a recognised biomarker for monitoring therapy response in metastatic hormone-sensitive prostate cancer (mHSPC), with clinical practice guideline recommendations. The modern treatment of mHSPC relies on the combination of androgen deprivation therapy and androgen receptor (AR)-targeted agents (ARTA), with/without chemotherapy and prostate-pelvic radiotherapy. Patients achieving a deep PSA response to intensified treatment for mHSPC have improved overall survival. However, treatment-emergent disease variants develop under intense AR inhibition that do not secrete PSA or are oligo-secretory, impairing the detection of disease progression. [...]
