Q1 (a) This data map illustrates the metastasis rate of perigastric lymph nodes in proximal gastric cancer patients after neoadjuvant chemotherapy. Lymph nodes surrounding the proximal part of the stomach, such as No. 1/2/3/7, exhibit the highest metastasis rate (17.3% ~ 30%). Key distal lymph nodes, including No. 5/6/12a, have a collective metastasis rate of 10%. b This heatmap provides a visualization of the metastasis rate of grouped perigastric lymph nodes
