Gene Signature for Predicting Solid Tumors Patient Prognosis
HCC is the most frequent malignant tumor in the liver and the third leading cause of cancer death worldwide. A progressive sequence of somatic mutations and epigenetic changes of oncogenes or tumor suppressor genes are believed to cause tumor development. However, high genomic instability in tumors causes the accumulation of genomic aberrations that do not contribute to tumor progression. Therefore, it is important to distinguish between ''driver'' mutations that are functionally important and ''passenger'' mutations that do not provide a selective advantage to the tumor cells.
