Our
@JUrology paper looked at 251 patients with TaHG tumors. All treated with adequate BCG. We stratified them by risk groups - "intermediate-risk" vs "high-risk" - based on clinical factors like tumor size, age, multifocality.
All TaHG tumors behaved the same: BCG unresponsiveness: 14% vs 13%
Stage progression: 13% in both groups.
MIBC or metastasis: 6.5% vs 5.9%.
Multicenter cohorts and AI-based pathology studies have since shown the same thing: the clinical factors used to downgrade TaHG to intermediate risk do not meaningfully discriminate outcomes.
Once a Ta tumor is high grade, the biology drives the behavior.
