1Hepatocellular carcinoma: Review of disease and tumor biomarkers显示文摘Hepatocellular carcinoma(HCC) is a common malignancy and now the second commonest global cause of cancer death. HCC tumorigenesis is relatively silent and patients experience late symptomatic presentation. As the option for curative treatments is limited to early stage cancers, diagnosis in non-symptomatic individuals is crucial. International guidelines advise regular surveillance of high-risk populations but the current tools lack sufficient sensitivity for early stage tumors on the background of a cirrhotic nodular liver. A number of novel biomarkers have now been suggested in the literature, which may reinforce the current surveillance methods. In addition, recent metabonomic and proteomic discoveries have established specific metabolite expressions in HCC, according to Warburg's phenomenon of altered energy metabolism. With clinical validation, a simple and non-invasive test from the serum or urine may be performed to diagnose HCC, particularly benefiting low resource regions where the burden of HCC is highest.Jin Un Kim Mohamed I F Shariff Mary M E Crossey Maria Gomez-Romero Elaine Holmes I Jane Cox Haddy K S Fye Ramou Njie Simon D Taylor-Robinson 2016World Journal of Hepatology2016,8,10:13
2Alpha-fetoprotein before and after pegylated interferon therapy for predicting hepatocellular carcinoma development显示文摘AIM: To investigate factors that accurately predict hepatocellular carcinoma(HCC) development after antiviral therapy in chronic hepatitis C(CHC) patients. METHODS: CHC patients who received pegylated interferon and ribavirin were enrolled in this cohort study that investigated the ability of alpha-fetoprotein(AFP) to predict HCC development after interferon(IFN) therapy. RESULTS: Of 1255 patients enrolled, 665 developed sustained virological response(SVR) during mean follow-up period of 5.4 years. HCC was occurred in 89 patients, and 20 SVR patients were included. Proportional hazard models showed that HCC occurred in SVR patients showing AFP ≥ 5 ng/m L before therapy and in non-SVR patients showing AFP ≥ 5 ng/m L before and 1 year after therapy besides older age, and low platelet counts. SVR patients showing AFP ≥ 5 ng/m L before therapy and no decrease in AFP to < 5 ng/m L 1 year after therapy had significantly higher HCC incidence than non-SVR patients showing AFP ≥ 5 ng/m L before therapy and decreased AFP(P = 0.043). AFP ≥ 5 ng/m L before therapy was significantly associated with low platelet counts and high values of alanine aminotransferase(ALT) in stepwise logistic regression analysis. After age, gender, platelet count, and ALT was matched by propensity score, significantly lower HCC incidence was shown in SVR patients showing AFP < 5 ng/m L before therapy than in those showing AFP ≥ 5 ng/m L.CONCLUSION: The criteria of AFP < 5 ng/m L before and 1 year after IFN therapy is a benefical predictor for HCC development in CHC patients.Yasuto Takeuchi Fusao Ikeda Toshiya Osawa Yasuyuki Araki Kouichi Takaguchi Youichi Morimoto Noriaki Hashimoto Kousaku Sakaguchi Tatsuro Sakata Masaharu Ando Yasuhiro Makino Shuji Matsumura Hiroki Takayama Hiroyuki Seki Shintarou Nanba Yuki Moritou Tetsuya Yasunaka Hideki Ohnishi Akinobu Takaki Kazuhiro Nouso Yoshiaki Iwasaki Kazuhide Yamamoto 2015World Journal of Hepatology2015,7,19:3
