Abstract:
Objective:To date, a vast array of localization techniques for excisions of nonpalpable breast cancer (NBC) is available, but the best choice remains unclear. Although ultrasound localization (US) is a widely available and feasible tool, it has several disadvantages for excisions of NBC. The purpose of this study was to evaluate the use of indocyanine green-guided nonpalpable breast cancer lesion localization (INBCL) and to compare it with US.Methods:The clinical data of 78 consecutive patients who underwent breast-conserving surgery for NBC in Dalian Central Hospital from January 2014 to December 2019 were prospectively reviewed the. Of all 78 excision.42 (53.8%) were localized by INBCL and 36 (46.1%) by US. Patients with preoperatively diagnosed primary ductal carcinoma in situ and multifocal disease were excluded from the study.Results:Both techniques resulted in 100.0% retrieval of the lesions. The rate of clear margins was 90.5% (38/42) in the INBCL group compared to the 83.3% (30/36) in the US group ( P>0.05). The margin width at first excision for both INBCL and US series of patients was compared. In the INBCL series, 92.9% (39/42) of cases had a margin less than 5 mm, whereas for US series it was 72.2% (26/36)( P<0.05). When results of the excised tissue were taken into account, the mean specimen volume for INBCL was 58 cm 3, wheres for US excision it was larger at 73 cm3,but there was not significantly different ( P = 0.058). Conclusions:INBCL for NBCs is more accurate than US, because a smaller volume of the tissue may be excised by using the technique, without compromising margin status in nonpalpable lesions. Therefore INBCL is an attractive alternative to US.
