[Superoxide-neutralizing activity of blood serum in cases of primary multiple malignant tumors].

: An earlier investigation of the superoxide-neutralizing activity of blood serum sampled from patients with primary multiple malignancies detected for the first time RF-proteins as well as their tropism to the target organ from which tumor was removed 2-30 years before. A possible explanation may be that a general reaction of the body presented itself. The present study has led to a conclusion that, in cases of polyneoplasia, successful complex treatment of primary malignancy, carried out however for back, might be masked by RF-protein function: the latter "indicates" the presence of foci of malignancy which are not there any longer.
