Origen de la bandera roja

Definición	Aggressive HCC biology: macrovascular invasion (portal vein tumor thrombus segmental or main), AFP >1000 ng/mL at baseline (high tumor burden marker), tumor doubling-time <3 months, OR poorly differentiated histology on biopsy. Predicts worse OS regardless of BCLC stage; favors more-active 1L choice (atezo+bev > sorafenib).

Notas

IMbrave150 subgroup analysis: AFP >400 derives larger benefit from atezo+bev vs sorafenib (HR 0.55 vs 0.85 overall). Macrovascular invasion (Vp1-4) traditionally precluded surgical / loco-regional options, but doesn't preclude systemic ICI-combination.
