Glomerular electron-dense deposits and circulating immune complexes in patients with malignant tumours.

39 patients with malignant neoplasms were studied for the presence of paraneoplastic glomerular disease. The nephrotic syndrome was found in none of the patients. From 24 patients an adequate renal biopsy specimen was available for examination by electron microscopy. Glomerular electron-dense deposits were found in the biopsies of 11 patients, and in four of them the deposits were subepithelial. Circulating soluble immune complexes were detected in the sera of 14 patients. Deposits and circulating immune complexes occurred simultaneously with a highly significant correlation. Cell-mediated immunity was studied using skin tests to tuberculin and dinitrochlorobenzene (DNCB). Negative tests were seen mainly in patients with circulating immune complexes and/or glomerular deposits. Median survival time in patients with deposits or circulating complexes tended to be shorter than in those without.

Clinical contribution of bcl-2, p53 and Ki-67 proteins in pancreatic ductal adenocarcinoma.

The expression of apoptosis suppressing protein bcl-2, tumour-suppressor protein p53, and proliferation marker Ki-67 and their possible prognostic value were analysed in pancreatic ductal adenocarcinoma. Fifty-two % (34/64) of the samples were positive for bcl-2 and immunostaining were mainly localized in the cytoplasm of tumour cells. Bcl-2 expression was not related to tumour grade, DNA ploidy or S-phase fraction or to any clinical parameters. In univariate analysis bcl-2 expression predicted favourable outcome (p = 0.008). Positive nuclear staining for p53 was found in 40% (24/59) of samples and 80% (60/74) of the tumours were positive for Ki-67. p53 and Ki-67 expressions were not related to patient survival. According to our results, bcl-2 expression seems to be a predictor of disease outcome and may have some clinical value in human pancreatic cancer.
