A retrospective study incorporated 108 primary HCC specimens observed that the expression of Eg5 (KIF11) was about 8.3-fold elevated in tumor tissues compared to non-cancerous ones, and the relative Eg5 expression was demonstrated to be capable of indicating survival results of HCC patients, that patients with higher Eg5 expression were inclined to suffer worse OS and DFS. The gene discussed is KIF11; the disease is neoplasm.
