“…In the present paper ( 1 ), Leng et al have evaluated the multidisciplinary management of operable clinical T2–3 esophageal squamous cell carcinomas (ESCCs) by presenting two case reports to several experts, within different professions, on three continents: East-Asia (China, Japan, and Korea), America (the Unites States) and Europe (the Netherlands). The authors conclude that further research is needed to address the challenges in clinical staging, as it is found to be very difficult to differentiate between T2 and T3 tumors.…”
