Time-varying prognostic value of circulating tumor DNA in urothelial carcinoma: a systematic review and reconstructed patient-data meta-analysis

Tumor DNA in blood changes its ability to predict outcomes over time, suggesting when and how to use it matters for cancer monitoring.

This PubMed-indexed meta-analysis examines Time-varying prognostic value of circulating tumor DNA in urothelial carcinoma: a systematic review and reconstructed patient-data meta-analysis. The available abstract reports Circulating tumor DNA (ctDNA) increasingly guides adjuvant therapy and surveillance in urothelial carcinoma (UC), yet whether its prognostic effect is adequately summarized by a single pooled hazard ratio (HR), which assumes proportional hazards (PH), has not been formally evaluated We searched five sources for.
