Origen de la bandera roja

DefiniciónPCWG3-defined PSA progression on systemic prostate-cancer therapy: ≥25% rise from nadir + ≥2 ng/mL absolute increase, confirmed by a second value ≥3 weeks later. Triggers re-imaging + MDT consideration of next-line therapy switch — but NOT alone sufficient to change line if radiographic + clinical disease stable (per PCWG3 + STAR criteria).

Notas

PSA-only progression on ARPI / chemotherapy is common (~30-40% of patients show PSA flare or transient rise). PCWG3 explicitly cautions against line switch on PSA alone — radiographic progression (RECIST 1.1 for soft tissue, PCWG3 bone-scan rules) or new symptomatic events must accompany the PSA finding. This RF surfaces the signal for MDT; it does not auto-switch tracks. Action lives in monitoring schedule (re-image at PSA-progression event), not in `shifts_algorithm`.
