Is 99mTc-phytate better than 99mTc-human serum albumin as a radioactive tracer for sentinel lymph node biopsy in breast cancer?
Our historical analysis of the two radioactive agents used in different periods could not exclude the influence of the improved skill of the surgeons. However, because the specific accumulation of phytate in SLNs was greater than that of HSA, phytate might result in a higher SLN identification rate. Thus, 99mTc-phytate is better than 99mTc-HSA as a radioactive agent for SLNB in breast cancer.
This study suggests IMA harvesting is indeed a risk factor for PND following CABG.
