Among the therapeutic options for gastric cancer, surgery is an essential pillar for its treatment. Gastric cancer surgery consists of gastric resection with negative margins and radical lymphadenectomy in patients without distant metastases. It has been demonstrated over the years that radical lymphadenectomy in gastric cancer allows for adequate staging and improved long-term survival.\n\nIn order to perform a correct staging using the TNM system, it is necessary to resect at least 15 lymph nodes in the radical lymphadenectomy. For radical lymphadenectomy staging, the Japanese Gastric Cancer Association defined and subdivided nodal stations. Three types of lymphadenectomy are described according to oncologic gastric resections (D1, D1+ and D2), with D2 lymphadenectomy being the standard of treatment for locally advanced gastric tumors. Performing an insufficient or inadequate lymphadenectomy has been shown to negatively impact survival after gastrectomy in such a cohort.\n\nThe development of technology based on fluorescence guided by indocyanine green could improve the technique and results of D2 lymphadenectomy in patients with gastric cancer. There is evidence that the application of ICG in D2 lymphadenectomy increases the number of resected nodes, however, studies of higher scientific quality (randomized clinical trials) are needed. Furthermore, most studies in this field have focused on Eastern countries (Japan, Korea and China), where the percentage of early tumors and chemotherapy treatment is different from Western centers.\n\nTherefore, we propose a multicenter randomized clinical trial aimed at evaluating whether the application of ICG-guided fluorescence-based technology in D2 lymphadenectomy of locally advanced gastric cancer increases the number of resected nodes, improves the oncologic quality of the lymphadenectomy, and thus may increase overall survival and disease-free survival at 2 and 5 years postoperatively.",[78,79,80,81,82],"GASTRIC CANCER","Indocyanine Green (ICG)","Lymph Node Excision","Lymphadenectomy","Laparoscopic Gastrectomy",[84,85,86],"Multicenter randomized 1:1 clinical trial","indocyanine green","Laparoscopic gastrectomy with D2 lymphadenectomy","NOT_YET_RECRUITING","2025-03-18",{"date":90,"type":91},"2025-03-24","ACTUAL",{"date":93,"type":72},"2026-03-01",{"date":95,"type":72},"2032-12",{"name":5,"class":6},1]
