Abstract

NY-ESO-1 is one of the most immunogenic tumor antigens known to date. Spontaneous humoral and cellular immune responses against NY-ESO-1 are detected in a substantial proportion of patients with NY-ESO-1 positive cancers. NY-ESO-1 serum antibody is dependent on the presence of NY-ESO-1+ cancer cells, and antibody titers correlate with the clinical development of the disease. NY-ESO-1 serum antibody is associated with detectable NY-ESO-1-specific CD8+ T cell reactivity. High titers of NY-ESO-1 serum antibodies are found in patients with advanced NY-ESO-1+ malignancies. Urine samples of seropositive patients with normal kidney function were tested for NY-ESO-1 antibody by Western blotting and enzyme-linked immunosorbent assay (ELISA). Antibodies to NY-ESO-1 were found in the urine of patients whose NY-ESO-1 serum antibody titers were 1:10,000 or higher by Western blotting. In patients with weak (positive at 1:250, negative at 1:1,000) or no reactivity, urine antibody was not detectable. No urine NY-ESO-1 antibody was found in patients without detectable NY-ESO-1 serum antibody. Our results show that urine analysis for NY-ESO-1 antibody identifies patients with strong NY-ESO-1 immunity. Urine antibody detection may also be of value in the monitoring of spontaneous and vaccine-induced immunity against other defined tumor antigens.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
