Clinical application of nano-carbon to improve the accuracy of lymph node staging in patients with advanced gastric cancer receiving neoadjuvant chemotherapy: a prospective randomized controlled trial

The significance of nano-carbon for lymph node staging in radical gastrectomy for gastric cancer (GC) has been confirmed, but studies on its application for GC patients treated with neoadjuvant chemotherapy (NCT) are rare. The purpose of this study was to explore the clinical value of using carbon nanoparticles suspension injections (CNS) to improve the accuracy of lymph node staging (N staging) of NCT for advanced GC.160 advanced GC patients...
