Abstract

Age-specific (<50, 50–69 years) 10-year survival proportions in four European trials for node-negative, Stage I and II breast cancer patients differ significantly. These patients, identified as having the same stage as localized-breast cancer patients in the End Results Registry of the U.S. National Cancer Institute, had pooled survival proportions for the two age groups (0.713, 0.579) close to those of the registry (0.713, 0.607).
