Zhang JJ, et al. - Experts performed a study in which ^99mTc-Rituximab was contrasted with filtered ^99mTc-sulfur colloid (fTcSC) for sentinel lymph node (SLN) detection in individuals with breast cancer. The variation existed in the internal mammary and clavicular area, and not in the axillary. ^99m-Rituximab showed a notably quicker injection site clearance rate in comparison with fTcSC. In conclusion, between the two tracers, no notable variation was seen in the recognition rate and the number of axillary SLN imaging and SLN biopsy. Furthermore, in comparison with fTcSC, ^99mTc-Rituximab based imaging exhibited a less number of secondary lymph nodes and had a quicker injection site clearance rate.
