No metastasis in the lymph nodes of the lesser curvature of the stomach means that the lymph nodes of the lesser curvature of the stomach are cleared during the surgery for gastric cancer, and the results of the sent pathological examination suggest that no metastasis is found in the lymph nodes of the lesser curvature of the stomach. Early gastric cancer that is not suitable for endoscopic surgery as well as progressive gastric cancer need to be treated by radical surgery, and the nearby lymph nodes need to be cleared. The lesser curvature of the stomach is the upper edge of the anterior and posterior walls of the stomach, which is curved, and the lymph nodes in the lesser curvature of the stomach are the regional lymph nodes distributed near the lesser curvature of the stomach. Regardless of early or progressive gastric cancer, radical surgery needs to routinely clear the lymph nodes in the lesser curvature of the stomach, i.e. group 3 lymph nodes. The cleared lymph nodes in the lesser curvature of the stomach can be sent for pathological examination during the operation to determine whether they are non-metastatic, micrometastatic or macrometastatic. The lesser curvature lymph nodes are group 1 of the perigastric lymph nodes, and generally need to be combined with other perigastric lymph nodes, as well as more distant perivascular lymph node metastases. Consultation with a specialist is recommended to choose a subsequent surgical treatment plan based on the results of the pathology report.
