Study Arms:
- Cryosurgery and NK immunotherapy (Type: EXPERIMENTAL): 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).
- Cryosurgery (Type: ACTIVE_COMPARATOR): In this group, the patients will receive comprehensive cryosurgery to destroy all big tumors. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets, circulating tumor cell).

Based on this trial design, predict the completion outcome and termination type (if applicable).
