Questions About a Risk Prediction Model of Mortality After Esophagectomy for Cancer

JAMA Surg. 2022;157(3):279. doi:10.1001/jamasurg.2021.5698

To the Editor D’Journo and colleagues1 must be commended for having developed and validated a risk prediction model of death within 90 days after esophagectomy for cancer using the International Esodata Study Group database. However, as the area under the receiver operating characteristic curve was only 0.64 (95% CI, 0.60-0.69), improving the variables to factor into the prognostic score is necessary.
