[Antirecurrence action of preparations made from Listeria in the surgical removal of sarcoma 180].

It is shown that in spite of the absence of the marked inhibition of the tumour growth in the preparative period listeria preparations decreased the percentage of recurrances. Based on the results obtained a conclusion is drawn that injection of listeria preparations into the tumour for several days before its surgical removal may be an effective prophylactic means of the relapse development.
