METHODS： Fifty patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were： （1） histological assessment of tumor grade by means of percutaneous biopsies; （2） determination of AFP mRNA status in the blood; （3） patient＇s eligibility for radical therapies. RESULTS： At preoperative evaluation, 54% of the study group had a well-differentiated HCC, 42% had AFP mRNA in the blood, 40% had a tumor larger than 5 cm and 56% had more than one nodule. Surgery （resection or liver transplantation） was performed in 29 patients, while 21 had percutaneous ablation procedures. After a median follow-up of 28 too, 12-, 24-, and 36-mo survival rates were 78%, 58%, and 51%, respectively. Surgical therapy, performance status and three tumor-related variables （AFP mRNA, HCC grade and gross vascular invasion） resulted as significant survival predictors at univariate analysis. Nodule size and number did not perform as significant prognosticators. Multivariate study selected only surgical therapy and a biologically early HCC profile （AFP mRNA negative and well-differentiated tumor without gross vascular invasion） as independent survival variables. CONCLUSION： The preoperative determination of tumor grade and blood AFP mRNA status may potentially refine the prognostic evaluation of HCC patients and improve the selection process for radical therapies.展开更多
