Nine children aged 2-7 years have been treated with anti-cancer immunotherapeutic vaccines. Before the onset of immunotherapy all patients exhibited signs of continued tumor growth. Over the follow-up period, patients received no systemic therapy other than immunotherapy. Two-year follow-up showed apparent long-term benefits from vaccine therapy in all patients. Final data analysis showed that all vaccine-treated patients were alive and led an active life. Although the results obtained in our clinical study are very promising, they must be interpreted with caution because of a small number of patients treated.
