Comparison of Autogenic and Allogenic NK Immunotherapy on the Outcome of Recurrent Solid Tumors

Study Overview
=================
Brief Summary
-----------------
The aim of this study is the efficacy of autogenic and allogenic natural killer (NK) immunotherapy on recurrent solid tumors.

Detailed Description
-----------------
By enrolling patients with multiple kinds of solid tumor adapted to enrolled criteria, this study will document for the first time the short/long term efficacy of auto/allogenic NK cells.The outcome will be evaluated according to local relief degree, progress free survival (PFS) and overall survival (OS).

Conditions
-----------------

Intervention / Treatment
-----------------
* Biological: NK immunotherapy
