Postoperative intra-abdominal infectious complications adversely affect OS and RFS. Meticulous surgery is needed to decrease the complication rate and improve the long-term outcome of patients following curative gastrectomy.

Malnutrition before gastrectomy and at 1, 3, 6 and 12 months after gastrectomy significantly and adversely affects overall survival. Nutritional interventions to lessen the impact of postoperative malnutrition offer hope for prolonged survival.

A detailed assessment of LVI is essential to the pathological evaluation of endoscopically resected specimens. An additional surgical resection should be strongly recommended for patients with LVI.

Prophylactic D4 dissection is not recommended for patients with potentially curable advanced gastric cancer.

Sarcopenia is related to poor survival in gastric cancer patients and appears to be a significant negative prognostic factor in patients with gastric cancer who underwent curative resection.
