Circulating Tumor DNA Positivity Predicts Survival in High-Grade pT1 NMIBC

We read with great interest the article by BinHumaid and colleagues [1], who report that positive preoperative circulating tumor DNA (ctDNA) status in 93 patients with high-grade pT1 non–muscle-invasive bladder cancer (NMIBC) was strongly associated with significantly worse overall and disease-specific survival. This elegant and innovative work extends the prognostic relevance of ctDNA beyond muscle-invasive disease and suggests that a subset of NMIBC cases harbor biologically aggressive and systemically detectable disease.

Clinical Editorial

Study design and population

Cohort of 93 patients with high-grade pT1 non–muscle-invasive bladder cancer analyzed for preoperative circulating tumor DNA status.

Key signal and outcomes

Positive ctDNA status prior to treatment associated with notably worse overall survival and disease-specific survival.

Context and implications

Authors suggest ctDNA extends prognostic relevance beyond muscle-invasive disease, indicating a subset of NMIBC with biologically aggressive, systemically detectable disease.
