Cryosurgery and NK immunotherapy
Cryosurgery
In this group, the patients will receive comprehensive cryosurgery first to destroy all big tumors, then receive multiple NK immunotherapy (intensive treatment: 6 times in first 3 months; then interval treatment: once every 3 months). The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets, circulating tumor cell).
