N2 - Background The purpose of this study was to investigate the use and clinical utility of carbon nanoparticles as a lymph node tracer in the central neck lymph node dissection of patients with papillary thyroid cancer. Methods One hundred forty consecutive patients were divided into a carbon nanoparticle group (n = 70) and a control group (n = 70). All patients underwent total or near-total thyroidectomy with bilateral central neck dissection. Results The carbon nanoparticle and control groups had different rates of metastatic lymph nodes (P = .017), total detected numbers of lymph nodes (P = .0001), total numbers of dissected lymph nodes <5 mm (P = .0001), and numbers of metastatic lymph nodes <5 mm (P = .0001). Of the 682 lymph nodes dissected in the carbon nanoparticle group, 579 (85%) were stained black, and of these, 147 (25%) were metastatic lymph nodes. There were 63 metastatic lymph nodes <5 mm among the black-stained metastatic lymph nodes, while there were 12 non–black-stained metastatic lymph nodes <5 mm. Of the total number of metastatic lymph nodes (n = 193), 147 (76%) were stained black. Moreover, pathologic results revealed that 5 accidental parathyroid resections occurred in the carbon nanoparticle group, compared with 14 in the control group (P = .046). Conclusion Carbon nanoparticles might help to detect lymph nodes and increase the number of metastatic lymph nodes visualized and preserved. Therefore, use of carbon nanoparticles may reflect the metastatic condition of the central neck and have the potential to protect parathyroid glands.
