Is There a Tumor Proportion Score Threshold at Which Tumor-Cell PD-L1 Adds Prognostic Information Beyond the International Prognostic Index in Large B-Cell Lymphoma? (PubMed, Diagnostics (Basel)) - Sep 27, 2026 - "No definition improved model fit or discrimination beyond the IPI; the null result held in DLBCL-NOS and R-CHOP subgroups. Tumor-cell PD-L1 did not add prognostic information beyond the IPI for overall survival."
