title: Anti-elastin antibodies in patients with lung cancer.
abstract: The aim of this study was to investigate anti-elastin antibodies of the IgG and IgM types in sera of patients suffering from lung cancer, using the DOT immunobinding assay. We studied 96 pathological and 40 control sera. Anti-elastin antibodies were found to be present in 45% of patients with small cell lung cancer, 19% of subjects with adenocarcinoma and not-identified lung tumor and 15% of patients with squamous cell lung cancer. They circulated in 5% of control persons only. The highest values of their titers were observed in the advanced stages of disease. In 55% of anti-elastin antibody positive small cell lung cancer patients, antibodies were of the IgM type, suggesting the initial step of the autoimmunization to elastin.
