Aims and objectives
With the development of mammography and the gradual popularization of breast cancer screening,
more and more non-palpable breast lesions have been detected.This type of non-palpable breast lesion can be positioned under mammography guidance,
followed by needle biopsy or local excision.The current standard for preoperative localisation technique in China is wire-guided localisation(WL) [1]. Although WL is simple and effective,
it has the following disadvantages: (1) The wire is exposed outside the body and the patient's comfort is low. (2) Wire can be displaced due to patient activity,
affecting positioning accuracy. (3) Positioning must be performed on the same day as surgery. (4) The diameter of the wire anchor hook is about 2 cm,
so it is not conducive to the accurate positioning of the lesion, and the anchor hook,which can reduce the negative rate of the cutting edge also increase the risk of reoperation [2]. In view of this,
several new methods have been tried to replace WL.
Studies [3-6] reported that radioactive seed localisation(RSL) is safe,
accurate,
not easily displaced,
has a higher margin negative rate,
and not affected by the operation time.
The Purpose of this study to compare the efficacy of radioactive seed localisation (RSL) and wire-guided localisation (WL) for intraoperative localisation of non-palpable breast lesions,
and to evaluate the application value of RSLin the diagnosis and treatment of non-palpable breast lesions .
