Inclusion Criteria: * Confirmed diagnosis of advanced esophageal cancer (phase IIIb-IV) according to NCCN clinical practice guidelines in Oncology:Esophageal and Esophagogastric Junction Cancers (2018.V1). * MUC1 is highly expressed in malignancy tissues by immuno-histochemical (IHC). * Eastern cooperative oncology group (ECOG) performance status of 0-1 or karnofsky performance status (KPS) score is higher than 60. * Patients have a life expectancy \> 12 weeks. * Adequate venous access for apheresis or venous sampling, and no other contraindications for leukapheresis. * Negative pregnancy test for females of child-bearing potentials. * Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: White blood cell count (WBC) ≥ 2500c/ml, Platelets ≥ 50×10\^9/L, Hb ≥ 9.0g/dL, lymphocyte (LY) ≥ 0.7×10\^9/L, LY% ≥ 15%, Alb ≥ 2.8g/dL, serum lipase and amylase \< 1.5×upper limit of normal, serum creatinine ≤ 2.5mg/dL, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5×upper limit of normal, serum total bilirubin ≤ 2.0mg/dL.

Recent or current use of inhaled steroids is not exclusionary. * Previously treatment with any gene therapy products. * The existence of unstable or active ulcers or gastrointestinal bleeding. Patients with portal vein vascular invasion or extrahepatic, are excluded from this study. * Patients with a history of organ transplantation or are waiting for organ transplantation.
