Core Tip
Core Tip: Gastric cancer (GC) is a major concern worldwide. According to Globocan there were 1089000 new cases of GC and 768000 GC related deaths worldwide in 2020 with almost twice the prevalence and mortality in males than in females. The highest prevalence is observed in Eastern Asia whereas the lowest in Africa. Gastrectomy is the mainstay approach in patients that can undergo surgery and in recent years with the advances in chemotherapy, neoadjuvant chemotherapy (NAT) has shown potential for better survival chances. That is particularly relevant in patients with locally advanced GC as NAT could potentially lead to tumor downsizing thus allowing for higher complete resection rate. In our review we compare patients receiving NAT and then undergoing D2 gastrectomy to those undergoing upfront surgery.
