Arm && Interventions

Group	Intervention	Description
POF	paclitaxel ,oxaliplatin,fluorouracil	A 3-hour infusion of paclitaxel (135 mg/m2) followed by oxaliplatin (85 mg/m2) and leucovorin (400 mg/m2), administered simultaneously over a 2-hour infusion period. Subsequently, a 46-hour infusion of fluorouracil (2400 mg/m2) was administered using an ambulatory pump, repeating every 14 days for 4 cycles

Primary Outcome Measures

Name	Time	Method
Pathological complete and subtotal regression (TRG1a/b by Becker)	after 4 cycles (each cycle is 14 days) + surgery; i.e. after 12 weeks in total	Pathological complete and subtotal regression (TRG1a/b by Becker). TRG1a/b is defined as \< 10% residual tumor per tumor bed based on evaluation of the resected esophagogastric specimen in the primary by a pathologist.
