OBJECTIVE: Wire localization is the most common localization method for non-palpable breast lesions, but it is uncomfort for patients, and has too many complications and easy to shift.It is important to explore new methods to make up for this defect.The purpose of this paper is to explore the application value and the efficacy of radioactive seed localization for intraoperative localization of non-palpable breast lesions before breast-conserving therapy.METHODS: Totally 135 women with non-palpab...更多

OBJECTIVE: Wire localization is the most common localization method for non-palpable breast lesions, but it is uncomfort for patients, and has too many complications and easy to shift.It is important to explore new methods to make up for this defect.The purpose of this paper is to explore the application value and the efficacy of radioactive seed localization for intraoperative localization of non-palpable breast lesions before breast-conserving therapy.METHODS: Totally 135 women with non-palpable breast lesions underwent breast-conserving surgery treated by Shandong Cancer Hospital and Institute from January 3, 2016 to January 3, 2019 were collected.There were 143 lesions .Radioactive seed localization was performed within 5 days before the surgery.Pathological examination were performed after the surgery, and the specimens were taken to mammography, lesion morphology and calcification range were compared with preoperative radiographs.The precision rate of location, the rates of tumor-free margin as well as the localization-related complications were recorded.RESULTS: The radioactive seed of 143 lesions were all in the resected specimens.All lesions were located precisely and removed completely.The first tumor-free margin rate of RSL was 90.21%, and no localization-related complication occurred in RLS group.CONCLUSIONS: RSL can be used for accurate location and guided resection of non-palpable breast lesions, the positioning of RSL is not affected by the operation time.RSL also has the higher tumor-free margin rate and lower re-excision rate.收起
