Ultrasound-assisted carbon nanoparticle suspension mapping versus dual tracer-guided sentinel lymph node biopsy in patients with early breast cancer (ultraCars): phase III randomized clinical trial.
Zhang L, Cheng M, Lin Y, Zhang J, Shen B, Chen Y et al.
Br J Surg 2022; 109: 1232–1238.
In this study that included 330 women, the sentinel node identification rate was similar: 94.5 per cent with ultrasound assistance versus 95.8 per cent with dual tracer. Number of sentinel nodes, number of metastatic nodes and duration of surgery were similar between the groups.
Comment: Ultrasound-assisted carbon nanoparticle mapping was non inferior.
