“…Cancer patients with sepsis are part of the main reasons for entering the ICU 15 . In a series of recent studies, when cancer patients in the ICU had sepsis, the mortality rate varied from 20% to 60% 16,17 . For the special population of cancer patients with sepsis, it is very important to find some simple and sensitive clinical variables to predict the risk of mortality from sepsis.…”

Background To develop a multiparameter‐based, easy‐to‐use nomogram and to predict the prognosis of cancer patients with sepsis in the intensive care unit (ICU). Methods Clinical data on cancer patients with sepsis who met the definition of sepsis 3.0 admitted to the ICU from January 2016 to October 2021 were collected. All patients were randomly entered into the development cohort or validation cohort according to the ratio of 7:3. Patients in the development cohort were divided into the survivors and the nonsurvivors according to the outcome of 28 days in ICU. The independent risk factors of mortality due to sepsis were screened out from the two groups (the survivors and the nonsurvivors) in the development cohort through multivariate logistic regression analysis. A nomogram was established with these independent risk factors, and the calibration plot was subsequently evaluated. Finally, the predictive power of the nomogram was verified in the validation cohort. Results A total of 317 cancer patients with sepsis who met the requirements were enrolled in this study, of which 229 entered into the development cohort and 88 entered into the validation cohort. The 28‐day mortality rates of the two cohorts were 17.5% and 20.5%, respectively. The neutrophil‐to‐lymphocyte ratio (NLR) on day 3 (d3), brain natriuretic peptide (BNP) d3, fluid accumulation at 72 hours (h), and Sequential Organ Failure Assessment (SOFA) score were independent risk factors for the 28‐day mortality between the survivors and the nonsurvivors in the development cohort. A nomogram was established on the above variables. The calibration plots fit well with the nomogram and had good statistical consistency in predicting the 28‐day mortality of sepsis (the C value was 0.938 and 0.968 in the two cohorts, respectively). With a nomogram score of 83.8 points, the diagnostic accuracy was 90.8% vs 92.0%, the sensitivity was 72.5% vs 77.7%, the specificity was 94.7% vs 95.7%, the positive predictive value was 72.3% vs 82.4%, and the negative predictive value was 94.2% vs 94.4% for predicting the 28‐day mortality in the development cohort and the validation cohort, respectively. Conclusion This easy‐to‐use nomogram based on NLR d3, BNP d3, and fluid accumulation at 72 h and SOFA score provides an accurate 28‐day prognosis prediction for cancer patients with sepsis admitted to the ICU.
