Then, patients were randomly split into the training (125 patients, 69.8%) and validation (54 patients, 30.2%) sets. To identify distant metastasis-associated lipids, univariate Cox regression was applied to the training set (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). A deep survival method called DeepSurv was employed to develop a proposed model based on significant lipid species (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01) and clinical biomarkers to predict DMFS. Concordance index and receiver operating curve analyses were performed to assess model effectiveness. The study also explored the potential role of lipid alterations in the prognosis of NPC.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Forty lipids were recognized as distant metastasis-associated (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05) by univariate Cox regression. The concordance indices of the proposed model were 0.764 (95% confidence interval (CI), 0.682\u20130.846) and 0.760 (95% CI, 0.649\u20130.871) in the training and validation sets, respectively. High-risk patients had poorer 5-year DMFS compared with low-risk patients (Hazard ratio, 26.18; 95% CI, 3.52\u2013194.80; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001).
