How do Gleason score and surgical margin status interact with PSA doubling time to predict metastasis?

Gleason score and PSA doubling time (PSADT) are strong, largely independent predictors of metastatic progression after radical prostatectomy, with higher Gleason grades and shorter PSADTs both linked ...

How should PSA kinetics and PSMA PET findings be integrated with margin and Gleason data when planning salvage radiation?

Salvage radiotherapy (sRT) planning should synthesize PSA kinetics (especially PSA doubling time), PSMA-PET findings, pathologic Gleason Grade Group, and margin status to stratify risk, decide on targ...

How sensitive are modern ultrasensitive PSA assays and how do they affect the undetectable threshold?

Modern "ultrasensitive" PSA assays push analytic detection down into the picogram-per-milliliter range—commonly reported as limits between roughly 0.001 and 0.003 ng/mL (1–3 pg/µL) and historically as...

When should androgen‑deprivation therapy be added to salvage radiotherapy after prostatectomy?

Androgen‑deprivation therapy (ADT) should be added to salvage radiotherapy (SRT) after radical prostatectomy when biochemical recurrence (BCR) is accompanied by high‑risk features—most guidelines and ...
