Abstract:
Objective To evaluate the value of metal spring ring for localization of breast lesions. Methods Thirteen cases of nonpalpable breast benign lesion and 41 cases of breast cancer that had been treated by neoadjuvant chemotherapy were enrolled in this study. The lesion was localized with the margin being marked under the guidance of ultrasonography. Metal spring rings with proper length was used according to the maximum diameter of the lesion; and then via a 18G puncture needle, the metal spring ring was place exactly to the two ends of the biggest cross-section of the lesion by using a guide wire. Afterwards, the lesions were resected with the spring ring. The 41 patients with breast cancer received 2-to 3-week chemotherapy after the operation. Results For the 13 cases of benign breast lesion, the mass was resected accurately and completely with the spring rings. In the 41 cases of breast cancer, no residual tumor cells were found in the tissues around the margin of resection. During the postoperative chemotherapy, ultrasonography showed that the mass was reduced in 39 of the cases, among which 9 had no clear margin of the tumor before the operation shown by ultrasonography. Off the 9 cases, postoperative pathological examination found no tumor cells in the successive sections. Conclusions Localization of breast lesions under the guidance of ultrasonography is a new method for diagnosis and treatment of nonpalpable breast lesions. It is valuable for follow-up by ultrasonography, evaluation of chemotherapy, and postoperative biopsy, especially for the breast cancer patients who have received preoperative chemotherapy.
