4. 4 Brief technology description Brief technology description prof. D.G.Zatula CAV prepared from autologous tumor cells and products of synthesis of a saprophytic microorganism B.subtilis B- 7025; CAV prepared from autologous tumor cells and products of synthesis of a saprophytic microorganism B.subtilis B- 7025; CAV introduced by hypodermic injections. The complete course consists of 3 injections with 7 day's interval. The revaccination will be carried out through 1 and 6 months; CAV introduced by hypodermic injections. The complete course consists of 3 injections with 7 day's interval. The revaccination will be carried out through 1 and 6 months; CAV prevented relapses and metastasis after surgery treatment, increased overall and relapse-free survival of patients; CAV prevented relapses and metastasis after surgery treatment, increased overall and relapse-free survival of patients; CAV is recommended as independent immunotherapeutic agent in the postoperative period. CAV is recommended as independent immunotherapeutic agent in the postoperative period.

5. 5 Advantages 1.Wide specter cancers forms, where CAV treatment could be used. 2.CAV produced from own cells of patients, so there is no any risk of SPID, or others infection diseases and its need no control methods concerning alien infection agents. 3.CAV is most effective at the late stages of cancer. 4.Effectiveness of CAV treatment may be compared, or better, then chemo- or radiotherapy, but without so characteristic for them toxic effects. 5.Cost of production and treatment by CAV more lower then chemo- or radiotherapy. 6.Combination to other methods of therapy: After radical operation (early stages of disease, the absence of metastasis) an effective utilization CAV without chemo- or radiotherapy. If it is necessary carryings out courses of chemo- or the radiotherapies immunotherapy by CAV may be started in 18-21 days after their end.
