Abstract
INTRODUCTION
Obtaining negative margins for patients undergoing breast-conserving surgery (BCS) for invasive lobular carcinoma (ILC) can be difficult because of the unique histologic pattern of ILC. Our goal was to determine whether any specific patient- or disease-related factors influenced margin status.
PATIENTS AND METHODS
We retrospectively reviewed 211 patients with ILC treated from 1994 through 2004 to determine if specific clinical and pathologic factors influenced the ability to obtain negative margins.
RESULTS
We identified 110 patients (52%) who underwent total mastectomy and 101 (48%) who underwent BCS. Among patients who underwent BCS, 50 (50%) had close or positive margins. Patients with close or positive margins were more likely to have architectural distortion on ultrasonography (vs. mass or calcifications; P = .049), to have undergone excisional biopsy (vs. core or fine-needle aspiration; P = .008), and to have associated ductal carcinoma in situ (P = .021). On multivariate analysis, only biopsy method retained significance (P = .006).
CONCLUSION
Core needle biopsy is the preferred method of diagnostic biopsy before surgical intervention. With appropriate patient selection, most patients with early-stage ILC can undergo successful BCS.
