AIM:To compare histological endpoint assessment using noninvasive alternatives to biopsy during treatment in a chronic hepatitis C virus(HCV)***:Patients with chronic HCV were randomized to receive interferon-based therapy for 24(genotypes 2/3)or 48(genotype 1)***~TM(FS)was assessed at baseline and at week-12 post-treatment *** biopsy for METAVIR was assessed by a single ***~ transient elastogra-phy(TE)was performed during treatment in a patient ***:Two thousand and sixty patients(n = 253 in Asia)were classif ied as METAVIR F0-1(n = 1682)or F2-4(n = 378).For F2-4,FS(n = 2055)had sensitiv-ity and specif icity of 0.87 and 0.61,respectively,with area under the receiver-operating curve of 0.82;corre-sponding values for TE(n = 214)and combined FS/TE(n = 209)were 0.77,0.88 and 0.88,and 0.93,0.68 and *** FS/TE agreement for F2-4 was 71%(κ = 0.41)and higher in Asians vs non-Asians(κ = 0.86 vs 0.35;P < 0.001).Combined FS/TE had 97% accuracy in Asians(n = 33).Baseline FS(0.38 vs 0.51,P < 0.001)and TE(8.0 kPa vs 11.9 kPa,P = 0.006)scores were lower in patients with sustained virological response than in nonresponders,and were maintained through ***:FS and TE may reliably differentiate mild from moderate-advanced disease,with a potential for high diagnostic accuracy in Asians with chronic HCV.
