Objectives : The aim of this study was to examine the details of breast-conserving surgery using a surgical instrument for circular partial mastectomy that we developed.
Patients and Methods : We performed partial mastectomy using our new instrument in 24 breast cancer patients. Breast cancer tumor was located in the central part of the breast tissue planned for excision. After grasping breast tissue with the instrument, we performed resection close to the circumference of the instrument and measured the time required for resection in a circular form. The specimen was sectioned into 5-mm-thick slices after formalin fixation, then we measured the distance from the tumor to both edges of the tissue specimen.
Results : Partial mastectomy was performed safely using the 5-, 6- and 7-cm diameter instruments for all 24 patients. Median resection time was 3 min 27 s (range, 1 min 32 s to 6 min 46 s) . T-test showed no significant difference between sides in mean distance from tumor to the section edge (left, 1.98 ± 0.12 cm ; right, 2.02 ± 0.11 cm) , confirming that tumors were located without deviation to one side of the resection margin in the resected specimen.
Conclusions : This device is a useful tool in the circular partial mastectomy of the breast in breast-conserving surgery.
