Evaluation of genetic instability of short tandem repeats in hepatocellular carcinoma.

ABSTRACT: Hepatocellular carcinoma (HCC) ranked as the sixth most common malignancy and the third leading cause of cancer-related mortality with approximately 830, 000 deaths worldwide annually. Genetic instability of short tandem repeats (STRs), which manifested as loss of heterozygosity (LOH) or microsatellite instability (MSI) in the cancerous cells, is a genetic feature of many types of human cancers. The status of STR instablility and its clinical significance in HCC, however, remains to be comprehensively elucidated. In this study, a total of 101 matched DNA samples from HCC individuals were analyzed with 20 "classical STR markers widely used in forensic genetics, our findings demonstrated that 79.21% (80/101) of HCC cases exhibited genetic alterations in at least 1 STR locus, with 16.73% of S
