Cytokeratin 19-9 (CYFRA 21-1) protein is elevated in the urine of endometriosis patients, indicating its potential as an early diagnostic marker for this chronic inflammatory disease.

This narrative review discusses endometriosis as a chronic inflammatory disorder and proposes that invasion and proliferation processes could drive increased synthesis of certain proteins that are subsequently excreted in urine. It focuses on CYFRA 21-1, a protein derived from cytokeratin 19-9, stating that it is enhanced in urinary secretion in patients with endometriosis and may function as a potential marker, particularly in early stages where imaging cannot reliably suggest or target the diagnosis. The paper does not provide new primary data and, as a review, acknowledges etiopathogenesis remains insufficiently clarified with multiple theories. This paper is centrally about endometriosis—specifically evaluating CYFRA 21-1 in urine as a potential early-stage marker.

Abstract

Endometrioza je kronična upalna bolest karakterizirana pojavom i rastom endometrija izvan maternice. Etiopatogeneza nije razjašnjena, a postoji više teorija nastanka endometrioze. Patološki procesi prisutni u endometriozi jesu adhezija, invazija, proliferacija, angiogeneza i promijenjena imunost. Moguće je da procesi invazije i proliferacije uzrokuju povećanu sintezu određenih proteina koji se zatim izlučuju urinom. Protein citokeratin 19-9 (CYFRA 21-1) pojačano se izlučuje u urinu pacijentica s endometriozom te je potencijalni marker u ranim stadijima ove bolesti kada nije moguće slikovnim metodama postaviti sumnju na bolest ili ciljanu dijagnozu.
