A number of conventional histopathologic features have been associated with recurrence of ductal carcinoma in situ (DCIS) after surgery alone and are included in the Van Nuys Pathologic Classification and Prognostic Index. To the authors' knowledge, very little is known regarding the prognostic significance of the many biologic markers that have been studied in DCIS in the past decade. ⋯ The current results confirmed the value of conventional histopathologic parameters, as outlined in the Van Nuys classification system, in predicting local recurrence of DCIS. Using traditional logistic analyses, no significant correlation was found between a variety of biologic markers and disease recurrence.
