Test characteristics of the Centers for Medicare and Medicaid Services (CMS) disease-free survival algorithm*

Censoring Period Sensitivity (95% CI) Specificity (95% CI) Area under ROC (95% CI)
2 y 83% (36% to 100%) 95% (83% to 100%) 84% (66% to 100%)
5 y 100% (81% to 100%) 97% (83% to 100%) 97% (90% to 100%)
*

The test characteristics were estimated by comparing CMS files with gold-standard clinical trial data pertaining to 45 elderly women with lymph node–positive breast cancer treated on the adjuvant chemotherapy trial CALGB 9344. CI = confidence interval; ROC = receiver operator curve.
