Core Tip

Core Tip: Staging laparoscopy (SL) upstaged nearly one in five patients with clinically resectable gastroesophageal junction cancer by revealing occult peritoneal or hepatic metastases. This finding underlines the value of SL in refining staging and guiding treatment decisions. Diagnostic performance was especially high in Siewert II tumors, without any significant heterogeneity. However, key procedural and patient-related data were not appropriately reported across studies. These results support the routine use of SL in staging gastroesophageal junction tumors and highlight the urgent need for standardized reporting to improve risk stratification and clinical outcomes in this challenging and heterogeneous cancer subgroup.
