Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

By enrolling patients with recurrent laryngeal 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 natural killer (NK) 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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cryosurgery and NK immunotherapy

In this group, the patients will receive comprehensive cryosurgery to clear all big tumors and then receive multiple NK immunotherapies. The check indexes are CT scan and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell).

Group Type EXPERIMENTAL

Cryosurgery

Intervention Type DEVICE

Percutaneous ablation under CT or ultrasound guidance

NK immunotherapy

Intervention Type BIOLOGICAL

Each treatment: 8\~10 billion cells in all, transfuion in 3 times, i.v.

Cryosurgery
