However, solid evidences regarding its oncologic benefit is still scarce.  Aim:  To evaluate the incidence of metastatic omental lymph nodes (LN) in patients undergoing curative gastrectomy for GC, as well as its risk factors and patients\u2019 outcomes.  Methods:  All consecutive patients submitted to D2\/modified D2 gastrectomy due to gastric adenocarcinoma from March 2009 to April 2016 were retrospectively reviewed from a prospective collected database.  Results:  Of 284 patients included, five (1.8%) patients had metastatic omental LN (one: pT3N3bM0; two: pT4aN3bM0; one: pT4aN2M0 and one pT4bN3bM0). Four of them deceased and one was under palliative chemotherapy due relapse. LN metastases in the greater omentum significantly correlated with tumor\u2019s size (p=0.018), N stage (p&lt;0.001), clinical stage (p=0.022), venous invasion growth (p=0.003), recurrence (p=0.006), site of recurrence (peritoneum: p=0.008; liver: p=0.023; ovary: p=0.035) and death (p=0.008).  Conclusion: The incidence of metastatic omental LN of patients undergoing radical gastrectomy due to GC is extremely low. Total omentectomy may be avoided in tumors smaller than 5.25 cm and T1\/T2 tumors. However, the presence of lymph node metastases in the greater omentum is associated with recurrence in the peritoneum, liver, ovary and death.<\/jats:p>","DOI":"10.1590\/0102-672020180001e1425","type":"journal-article","created":{"date-parts":[[2019,2,9]],"date-time":"2019-02-09T18:23:16Z","timestamp":1549736596000},"source":"Crossref","is-referenced-by-count":19,"title":["TOTAL
