Prognostic Role of Serum Cytokeratin-19 Fragment (CYFRA 21-1) in Patients with Hepatocellular Carcinoma

Abstract: Keratin 19 (K19) is a cancer stem cell marker expressed by a subpopulation of hepatocellular carcinoma (HCC), associated with tumor aggressiveness. We evaluated the prognostic value of serum K19 fragment (CYFRA 21-1), in comparison or in combination with alpha-fetoprotein (AFP) and protein induced by vitamin-K absence or antagonist-II (PIVKA-II), in patients with HCC. A total of 160 patients (28F/132M; median age 62, range 44–86 years) with a new diagnosis of HCC and available serum samples collected at tumor … Show more

“…Serum levels of AFP and PIVKA-II were determined on the fully automated chemiluminescent enzyme immunoassay (CLEIA) system Lumipulse ® G600 II (Fujirebio Inc., Tokyo, Japan) using Lumipulse ® G AFP-N and Lumipulse ® G PIVKA-II reaction cartridges according to manufacturer's instructions. AFP concentrations were given in ng/mL, while PIVKA-II values were reported in mAU/mL [37].…”

“…The prognosis of HCC varies greatly according to the tumor stage at diagnosis and overall liver function status; therefore, a timely detection of the tumor is crucial in order to allow curative treatments and thus to improve patients’ survival [ 6 , 7 ]. According to international guidelines, surveillance for HCC should be performed in patients at risk for tumor development by means of ultrasound (US), with or without the measurement of serum alpha-fetoprotein (AFP) [ 8 , 9 ], while the Barcelona Clinic Liver Cancer (BCLC) staging system should be adopted for HCC prognostication and treatment allocation [ 8 , 9 ].…”

“…CSCs were reported to be associated with tumor growth, resistance to systemic chemotherapy and epithelialmesenchymal transition, and are related to the prognosis of solid cancer patients [30]. There are a few reports that high CYFRA21-1 level is related to increased tumor size, metastasis and microvascular invasion [31]. Furthermore, high CYFRA21-1 level in HCC patients is reported to reflect Keratin 19 (K19) expression.…”
