FIELD: medicinal oncology. SUBSTANCE: oncologic patient's peripheral blood is subjected to analysis in order to determine following parameters: absolute number of T-and B-lymphocytes in blood (x109/1), number of o-cells, number of T-early, sedimentless, restored, stable, theophylline-sensitive and theophylline-resistant lymphocytes, circulating blood volume. Total number of populations of T- and B-lymphocytes, O-cells, populations of T-, sedimentless, restored, stable, theophylline- sensitive and theophylline-resistant lymphocytes is determined using formulae Ntot = N - lymphocytes or O-cells x CBV, followed by calculating ratio indices of total population numbers of immunocompetent cells to average diameter of tumor using formulae: Ttot/D, Btot/D, Otot/D, Tran tot/D, Tbez tot/D, Tvos tot/D, Tst tot/D, TFHtot/D, TFRtot/D. If two or less positive index values are obtained in relation to threshold level value, oncologist diagnoses absence of remote metastases, whereas in case of presence of three and more positive index values, oncologist diagnoses presence of remote metastases of malignant neoplasms in oncologic patients. EFFECT: greater accuracy in diagnosis. 2 tbl
