Factors Associated With Underestimation of Invasive Cancer in Patients With Ductal Carcinoma In Situ

Abstract

When selecting patients for active surveillance of DCIS, factors other than tumor biology associated with invasive carcinoma based on final pathologic findings may need to be considered. At the time of randomization to active surveillance, a significant proportion of patients with non-high-grade DCIS will harbor invasive carcinoma.
