Brief Summary:
The aim of this study is the safety and efficacy of cryosurgery plus NK immunotherapy to advanced esophageal cancer.

Condition or disease Intervention/treatment Phase
Metastatic Esophageal Cancer Device: Cryosurgery Biological: NK immunotherapy Phase 1 Phase 2

Detailed Description:

By enrolling patients with pancreatic cancer adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of the combined therapy using cryosurgery and nature killer (NK) cells for advanced esophageal cancer.

The safety will be evaluated by statistics of adverse reactions.The efficacy will be evaluated according to local relief degree, progress free survival (PFS) and overall survival (OS).
