BACKGROUND The combination of alpha-fetoprotein(AFP)and squamous cell carcinoma antigen immunocomplex(SCCA-IgM)have been proposed for its use in the screening of hepatocellular carcinoma(HCC).Current screening programs for all cirrhotic patients are controversial and a personalized screening is an unmet need in the precision medicine *** To determine the role of the combination of SCCA-IgM and AFP in predicting mid-and long-term appearance of *** Two-hundred and three cirrhotic patients(Child A 74.9%,B 21.2%,C 3.9%)were followed-up prospectively every six months to screen HCC by ultrasound and AFP according to European Association for the Study of the Liver *** estimation cohort was recruited in Italy(30.5%;62/203)and validation cohort from Spain(69.5%;141/203).Patients underwent to evaluate SCCA-IgM by enzyme-linked immunosorbent assay(Hepa-IC,Xeptagen,Italy)and AFP levels at *** were followed-up for 60 mo,being censored at the time of the appearance of *** There were 10.8%and 23.1%of HCC development at two-and five-years *** with HCC showed higher levels of SCCA-IgM than those without it(425.72±568.33 AU/mL vs 195.93±188.40 AU/mL,P=0.009)during the fiveyear *** multivariate analysis,after adjusting by age,sex,aspartate transaminase and Child-Pugh,the following factors were independently associated with HCC:SCCA-IgM[Hazard ratio(HR)=1.001,95%CI:1.000-1.002;P=0.003],AFP(HR=1.028,95%CI:1.009-1.046;P=0.003)and creatinine(HR=1.56495%CI:1.151-2.124;P=0.004).The log-rank test of the combination resulted in 7.488(P=0.024)in estimation cohort and 11.061(P=0.004)in the validation cohort,and a 100%of correctly classified rate identifying a low-risk group in both cohorts in the two-year *** We have constructed a predictive model based on the combination of SCCA-IgM and AFP that provides a new HCC screening method,which could be followed by tailored HCC surveillance for individual patients,esp

Clinical applications of squamous cell carcinoma antigenimmunoglobulins M to monitor chronic hepatitis C

引用

World Journal of Hepatology 2015年第29期7卷 2913-2919页

作者： Andrea Martini Andrea Gallotta Patrizia Pontisso giorgio fassina Department of Medicine University of Padua Xeptagen S.p.A. VEGA Science Park

Hepatitis C virus(HCV) is the main cause of chronic liver disease and cirrhosis in Western countries. Over time, the majority of cirrhotic patients develop hepatocellular carcinoma(HCC), one of the most common fatal cancers worldwide- fourth for incidence rate. A high public health priority need is the development of biomarkers to screen for liver disease progression and for early diagnosis of HCC development, particularly in the high risk population represented by HCV-positive patients with cirrhosis. Several studies have shown that serological determination of a novel biomarker, squamous cell carcinoma antigen-immunoglobulins M(SCCA-Ig M), might be useful to identify patients with progressive liver disease. In the initial part of this review we summarize the main clinical studies that have investigated this new circulating biomarker on HCV-infected patients, providing evidence that in chronic hepatitis C SCCA-Ig M may be used to monitor progression of liver disease, and also to assess the virological response to antiviral treatment. In the last part of this review we address other, not less important, clinical applications of this biomarker in hepatology.

To the Editor: As we all know, even with the current advancements regarding novel chemotherapy regimens, patients affected by pancreatic cancer(PC) have an extremely dismal prognosis(5-year survival rate 12% for all stages in the National Cancer Institute SEER database). Among the patients undergoing surgical treatment, the prognosis is mostly affected by recurrence. PC after surgery has mainly four patterns of recurrence, isolated or variously associated with each other: local, lymph nodal, peritoneal or distant(liver, lung, other sites).
