Objective To investigate the differences between indocyanine green (ICG) plus methylene blue and radioactive nuclide plus methylene blue for sentinel lymph node biopsy (SLNB) after Neoadjuvant chemotherapy (NAC) in breast cancer patients. Methods  A total of 77 breast cancer patients who accepted SLNB and axillary lymph node dissection (ALND) after NAC from June 2017 to February 2019 were involved, among them, 46 breast cancer patients accepted SLNB by ICG plus methylene blue and 31 breast cancer patients accepted SLNB by radioactive nuclide plus methylene blue, pathological and clinical data were collected and analyzed.Results There were 43 patients in the ICG plus methylene blue group and 30 patients in radioactive nuclide plus methylene blue group, which totally 73 patients were detected at least one sentinel lymph node in all the 77 patients, and the detection rate was 94.80%. The SLN detected rate, SLN detected numbers, sensitivity, false negative rate, and accuracy of the ICG plus methylene blue group were 93.48% (43/46), 2.32 per case, 82.61% (19/23), 17.39% (4/23), and 90.70% (39/43) respectively, as well as 96.77% (30/31), 2.6 per case, 83.33% (10/12), 16.67% (2/10), and 93.33% (28/30) in the radioactive nuclide plus methylene blue group. There was no significant difference between the ICG plus methylene blue group and radioactive nuclide plus methylene blue group in terms of SLN detected rate, SLN detected numbers, sensitivity, false negative rate, and accuracy (P>0.05).Conclusion ICG plus methylene blue showed similar SLN detection rate, SLN detected numbers, sensitivity, false negative rate, and accuracy as radioactive nuclide plus methylene blue for SLNB in breast cancer patients after NAC, and both of them can be performed easily and conveniently.
