Benefits of technology

[0010] This invention further provides a method for determining the prognosis of a subject afflicted with hepatocellular carcinoma (HCC), comprising: (a) obtaining a tumor sample from the subject; (b) determining the level of CLDN10 nucleic acid transcript in the tumor sample; (c) comparing the level of CLDN10 nucleic acid transcript from step (b) with the level of CLDN10 nucleic acid transcript in the normal tissue sample, whereby a higher level of CLDN10 nucleic acid transcript in step (b) indicates a poor prognosis.
[0011] This invention also provides a method for determining the prognosis of a subject afflicted with hepatocellular carcinoma (HCC), comprising: (a) obtaining a tumor sample from the subject; (b) determining the level of AA454543 nucleic acid transcript in the tumor sample; (c) comparing the level of AA454543 nucleic acid transcript from step (b) with the level of AA454543 nucleic acid transcript in the normal tissue sample, whereby a higher level of AA454543 nucleic acid transcript in step (b) indicates a poor prognosis.

Problems solved by technology

However, conventional clinico-pathological parameters have limited predictive power, and patients with the same stage of disease can have very different disease outcomes.

Synopsis:

[0118] Dynein, axonemal, light intermediate polypeptide 1 (DNALI1) expression was found to significantly associate with disease recurrence (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.1-2.6, P=0.014) as shown in our earlier genome-wide expression study by cDNA microarray approach on hepatocellular carcinoma (HCC). This study was performed on an independent sample set (n=50) and employed quantitative RT-PCR to examine the DNALI1 transcript level. The association of higher DNALI1 expression level with early disease recurrence was again confirmed. Our preliminary sequencing study indicated that DNALI1 had a polymorphism at nucleotide 194 (codon 65), which either harbored the C-allele (GCA, alanine) or T-allele (GTA, valine). We then further examined the blood samples of the patients for the nucleotide 194 polymorphism (n=50, paralleled samples where the HCCs had quantitative RT-PCR data). The tumor DNALI1 transcript level was significantly higher in patients with T...
