Brief Summary

Papillary thyroid cancer (PTC) is the most common subtype of thyroid cancer. The most common site of PTC nodal metastases is the central neck, which has a reported rate of lymph node metastases as high as 50%\~70%. Central neck dissection has important value to ensure accurate clinical staging and surgical planning. As a novel lymphatic tracer, carbon nanoparticles (CN) have been applied successfully in the detection of sentinel lymph nodes in breast and gastric cancers, while not been used as a lymphatic tracer for PTC. The goal of this study was to evaluate whether the use of CN facilitates the detection of lymph nodes, increases the number of metastatic lymph nodes removed, accurately reflects the metastatic condition of the central neck, and has the potential to protect the parathyroid glands.

Outcome Measures

Primary Outcomes (3)

  • lymph node metastatic rates between the carbon nanoparticles and control group

    one year

  • total dissected lymph nodes less than 5mm between the carbon nanoparticles and control group

    one year

  • the number of metastatic lymph nodes with diameter < 5mm between the carbon nanoparticles and control group

    one year

Study Arms (1)

carbon nanoparticles

EXPERIMENTAL

0.1 ml of CN suspension was injected per spot into the tissue surrounding the tumor using a skin test syringe. Two or three randomly selected spots were injected slowly for each tumor, and the total amount injected was no more than 0.5 mL per lobe.

Drug: carbon nanoparticles

Interventions
