To investigate the efficacy of autologous Natural killer (ANK) cell therapy in the treatment of advanced prostate cancer, we selected nine patients with advanced prostate cancer and metastatic lesions for this study. Approximately 1×109 ANK cells were injected into each patient every 2 weeks or every month. A combination of ANK cell injections were performed over 20 injections. During the course of therapy, we adopted face scale as measurement of quality of life (QOL) and the CD4+ to CD8+ T cell ratio served as a marker of immunological status. The administration of ANK cells resulted in prolonged survival (≥3 year) of all nine patients in our study. The QOL of each study participant remained satisfactory or improved, over the course of treatment and their immune status also improved following ANK cell therapy. The results indicate that ANK cell therapy is a safe and partially effective treatment for patients with advanced prostate cancer.
