High-activity Natural Killer Immunotherapy for Small Metastases of Non-small Cell Lung Cancer

Study Overview
=================
Brief Summary
-----------------
The aim of this study is the safety and efficacy of high-activity natural killer immunotherapy to small metastases of non-small cell lung cancer.

Detailed Description
-----------------
By enrolling patients with small metastases of non-small cell lung cancer adapted to enrolled criteria, this study will document for the first time the safety and the short and long term efficacy of high-activity natural killer cells. 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).

Conditions
-----------------
Non-small Cell Lung Cancer Metastatic

Intervention / Treatment
-----------------
* Biological: high-activity natural killer

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: High-activity natural killer<br>In this group, the patients will receive multiple times of high-activity natural killer (HANK) immunotherapies. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell). | Biological: high-activity natural killer<br>* Each treatment: 8 10 billion cells in all, transfuion in 3 times, i.v.<br>* Other names: HANK cell;|
| No Intervention: ControL<br>In this group, the patients will receive no special treatment and as a control group. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell). | |
