title: Evaluation of colloid size for sentinel nodes detection using radioisotope in early gastric cancer.
abstract: The purpose of this study was to investigate the relationship between colloid size and the detection of sentinel nodes (SN) in early gastric cancer. Three size of 99mTechnetium-tin colloids (500, 100 and 50 nm) were preoperatively injected into the submucosa under endoscopic control. Lymph node metastasis and micrometastasis was examined. RI-uptake in the hottest nodes and the total RI-uptake in the hot nodes were highest in the size of 100 nm. At least one lymph node metastasis, including micrometastasis, was included in the hot nodes. RI-labeled colloid size was one of the important factors to detect SN in early gastric cancer.
