The aim of the study was to analyze serum tumor necrosis factor alpha (TNF-) levels in different neoplasm types qualified for surgical treatment and to evaluate their possible correlations with circulating immune complexes (CIC), IgG, IgM, and thecomplement (C) compounds: C1 inhibitor (C1i), C3c and C4 levels. Studies were performed in sera from 30 neoplasm patients before surgical treatment and in 10 persons from a control group (CG) with no malignancy. Serum TNF- levels were measured with the Cytogen ELISA kit. Average TNF- levels measured in neoplastic patient groups qualified for surgical treatment were not significantly different from the average TNF- level in the CG group.

In the sera of 30 neoplasm patients without metastases, the average IgG level was higher than in the control group (CG) (18.16 + 5.10 versus 12.62 + 2.14 g/l or 12.22 + 2.14 after excluding an out-lier). Average concentrations of CIC, IgM, C1i, C3c and C4 did not statistically differ between the groups. Dividing the patients' group into breast or ovary cancer (BC), melanoma (M), digestive tract cancer (DT) and other neoplasms (ON) subgroups revealed that the IgG increase did not apply to the BC group. Relatively decreased CIC concentrations in the BC and DT group and an increased C1i in the DT group were found. Several diversities detected in the humoral immunity indices' distributions and correlations suggest activation of different mechanisms depending on the neoplasm types.
