Comorbidity Assessment in the National Cancer Database for Patients With Surgically Resected Breast Colorectal or Lung Cancer (AFT-01 -02 -03)

摘要

Purpose:Accurate comorbidity measurement is critical for cancer research. We evaluated comorbidity assessment in the National Cancer Database (NCDB), which uses a code-based Charlson-Deyo Comorbidity Index (CCI), and compared its prognostic performance with a chart-based CCI and individual comorbidities in a national sample of patients with breast, colorectal, or lung cancer.
