Abstract
Introduction
It is accepted that preoperative chemotherapy can result in increased breast preservation for breast cancers greater than 4 cm. The benefits of preoperative chemotherapy are less clear, however, for patients who present with smaller tumors and are already candidates for breast-preserving surgery. The goal of this study is to assess the effect of preoperative chemotherapy on breast cancers between 2 and 4 cm diameter.
Methods
A retrospective chart review was conducted of patients diagnosed with new breast cancer at the Yale-New Haven Breast Center for the years 2002–2007. Patients were included in the study if their breast cancer was between 2 and 4 cm and their initial surgical treatment had been completed. Patients with distant metastases were excluded.
Results
There were 156 new cancers that met study requirements. Forty-seven patients underwent preoperative chemotherapy, and 109 patients had their surgery first, usually followed by chemotherapy. Initial surgery was lumpectomy for 31 out of 47 patients (66%) in the preoperative chemotherapy group compared with 62 out of 109 patients (57%) in the surgery group. For patients with lumpectomies, 2 out of 31 patients (6%) in the preoperative group had positive margins and required re-excision compared with 20 out of 62 patients (37%) in the surgery-first group (P < 0.01).
Conclusions
We conclude that, for tumors between 2 and 4 cm, preoperative chemotherapy is associated with a significantly decreased rate of re-excision following lumpectomy. This not only results in fewer mastectomies, but also avoids the morbidity and inferior cosmetic results associated with a re-excision lumpectomy.
