Study Summary
Breast cancer is the most common malignancy affecting women in the US. Surgical management is the mainstay of therapy, and in general consists of resection of the primary tumor with either a partial mastectomy (aka "lumpectomy") or a total mastectomy. The investigators hypothesize that routine shave margins during partial mastectomy will significantly reduce positive margin rate. A positive margin means that cancerous cells were detected at the edge of the excised area. This generally mandates a return to the operating room for re-excision.
Primary Outcome
The effect is positive margin rate post-surgery as measured by local pathological reports. Positive margins were defined as tumor touching the edge of the specimen that was removed in patients with invasive cancer and tumor that was within 2 mm of the edge of the specimen removed in those with ductal carcinoma in situ.
Interventions
- PROCEDURE Partial mastectomy
- PROCEDURE Partial mastectomy plus additional Shave Margin
