Clinical Trial Summary

The aim of this study is the safety and efficacy of cryosurgery plus NK immunotherapy to advanced breast cancer.

Description:

By enrolling patients with breast 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 breast 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).
