Abstract
- The authors reviewed Niigata Cancer Center Hospital's experience treating patients with lumpectomy to evaluate the utility of three-dimensional helical computed tomography (3D-CT) image-guided made-to-order lumpectomy and determine a positive margin rate. From April 1993 to September 2000, 251 breasts in 248 patients were treated with lumpectomy with a 1 cm macroscopic free margin. In 213 breasts (85%), 3D-CT image-guided made-to-order lumpectomy was performed. Thirty-eight breasts (15%) underwent a lumpectomy without 3D-CT. The lumpectomy specimen was sectioned at 5 mm intervals. Margin status was classified as negative (no invasive or ductal carcinoma in situ (DCIS) within 2 mm from the cut surface) or positive. Positive margins were classified as focally positive (invasive or DCIS transected at the margin within 5 mm or one slide) or massively positive. With 3D-CT image-guided Iumpectomy, 21% (45/213) of lesions had a positive margin and 42% (16/38) of lesions without 3D-CT image-guided lumpectomy had a positive margin ( p = 0.0055). For lesions with massively positive margins, the rates were 9% (4/45) for 3D-CT image-guided lumpectomy and 38% (6/16) for lumpectomy without 3D-CT ( p = 0.0152). 3D-CT image-guided made-to-order lumpectomy decreased the positive surgical margin rate. Among patients with positive margins, those with 3D-CT image-guided lumpectomy have less residual cancer than those without 3D-CT. [ABSTRACT FROM AUTHOR]
