Abstract

Several recent trials have demonstrated that neoadjuvant chemotherapy can allow more patients to successfully undergo breast-conserving treatment (BCT), and does not confer a survival disadvantage compared with standard adjuvant chemotherapy. In addition, the pathological response of primary breast tumors to neoadjuvant chemotherapy appears to be a surrogate marker for patient outcome.

In our series, during the period from May 1995 to December 2000, 86 patients with tumors between 3.1 and 6.0 cm in diameter received epirubicin-based neoadjuvant chemotherapy. There were 55 (64.0%) responders and ultimately 64 patients (74.4%) were treated with BCT. The margin positive rate was 14.1% (9/64), similar to the rate after BCT for early-stage breast cancers, the largest diameter of which was smaller than 3 cm. At a median follow-up of 30 months, only 3 patients in the BCT group have developed local recurrence; the local recurrence rate appears to be comparable to that after BCT for early stage breast cancers. Long term follow-up is required, however, to establish whether this procedure is a safe alternative to mastectomy for patients with large breast cancers.
