title: Pre-operative levels of serum immunoglobulins, circulating immune complexes and complement proteins in patients with different types of neoplasms.
abstract: 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 vs. 12.62+/-2.14 g/l or 12.22+/-2.14 after excluding an outier). Average concentrations of circulating immune complexes (CIC), IgM, complement 1 inhibitor (Cli), 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 Cli 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.
