Prediction of early death in peripheral T-cell lymphoma-NOS patients based on machine learning
A machine learning tool identifies aggressive T-cell lymphoma patients at highest risk of early death, enabling faster treatment decisions.
An XGBoost machine learning model built on SEER data (n=1,156) predicted early death within 3 months in PTCL-NOS patients with AUROC 0.842 in training and 0.774 in validation, using 7 clinically accessible variables. This interpretable tool addresses a critical unmet need in aggressive T-cell lymphoma, where early risk stratification could guide treatment intensity decisions.

Why it surfaced
Large retrospective SEER cohort; XGBoost model with good AUROC for a rare aggressive lymphoma; practical 7-variable model; SEER-based limitations (administrative data, no molecular features) noted.
