SSB and neoplasm: The lupus-associated (La) antigen, also known by the HUGO Gene Nomenclature Committee approved name of Sjögren Syndrome B (SSB), is an abundant, essential, and ubiquitously expressed ribonucleoprotein that is revealed preferentially in dead tumour cells because La is over-expressed in malignancy[8-10] and dead tumour cells are inefficiently cleared in vivo unlike dead normal cells[10,11].
