Pre-transplant AFP, AFP-L3 and DCP were measured in 113 patients transplanted for HCC from 2000 to 2008. Hazard ratios(HR) for recurrence and death were calculated. Univariate and multivariate regression analyses were conducted. C-statistics were used to compare biomarker-based to predictive models. RESULTS During a median follow-up of 12.2 years, 38 patients recurred and 87 died. The HRs for recurrence in patients with elevated AFP, AFP-L3, and DCP defined by BALAD cut-off values were 2.42(1.18-5.00), 1.86(0.98-3.52), and 2.83(1.42-5.61), respectively. For BALAD, the HRs for recurrence and death per unit increased score were 1.48(1.15-1.91) and 1.59(1.28-1.97). For BALAD-2, the HRs for recurrence and death per unit increased class were 1.45(1.06-1.98) and 1.38(1.09-1.76). For recurrence prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs. 0.64, 0.61, 0.53, and 0.53 for BALAD, BALAD-2, Milan, and UCSF, respectively. Similarly, for death prediction, the combination of three biomarkers had the highest c-statistic of 0.66 vs 0.65,0.61, 0.52, and 0.50 for BALAD, BALAD-2, Milan, and UCSF. A new model combining biomarkers with tumor size at the time of transplant(S-LAD) demonstrated the highest predictive capability with c-statistics of 0.71 and 0.69 for recurrence and death. CONCLUSION BALAD and BALAD-2 are valid in transplant HCC patients, but less predictive than the three biomarkers in combination or the three biomarkers in combination with maximal tumor diameter(S-LAD).展开更多

Therefore, early screening of high-risk groups of HCC through simple methods is the key toachieving early diagnosis and treatment and improving survival. At present, alpha-fetoprotein and otherhematological tests are still the main methods in the early screening of HCC, but the sensitivity andspecificity are limited, and the risk of missed diagnosis is high. In recent years, with the continuousdevelopment of science and technology, the improvement of traditional detection methods and theemergence of novel markers such as methylated deoxyribonucleic acid and microRNA have brought hopefor further improving the sensitivity and specificity of early HCC screening. This consensus summarizesthe research progress of traditional and new hematological test methods and puts forward expertguidance on the role of hematological markers in the early screening of HCC to provide a basis forimproving the prevention and control level in China.展开更多
