Abstract
Recent meta-analyses and a prospective multicenter trial of sentinel lymph node (SLN) mapping and biopsy for early-stage gastric cancer have shown acceptable SLN detection rates and accuracy for determination of lymph node status. Although a combination of radioactive colloids with blue dyes as tracers is currently considered the most reliable method for stable gastric cancer SLN mapping, the new technologies such as indocyanine green infrared or fluorescence imaging may improve the SLN mapping procedures in gastric cancer. For early gastric cancer, the establishment of individualized, minimally invasive gastrectomy based on SLN concept can retain the patients’ quality of life. A recently developed full-thickness partial gastrectomy with SLN mapping and lymphatic basin dissection is expected to become a promising, ideal minimally invasive, function-preserving surgery to cure patients with clinical node-negative early gastric cancer.
