Task: Question Answering
Input (English): Context: Better prognosis of cancer including hepatocellular carcinoma (HCC) remains unsatisfactory due to recurrence and chemoresistance. In this respect it is important to identify molecular targets specific to the disease in order to design effective therapeutic strategies. In the present study, we investigated the prognostic role of Never-in-mitosis-A-related kinase 2 (NEK2) in HCC.', 'Fifty HCC patients who underwent hepatectomy were enrolled in the study. NEK2 gene and protein expression was examined by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry, respectively.', 'Higher expression of NEK2 was detected in HCC tumoral compared to adjacent non-tumor tissues (p<0.001), and protein expression was also relatively high in tumor than corresponding non-tumor tissues. Furthermore, high NEK2 expression was positively correlated with hepatic venous invasion (p=0.047), des-gammacarboxy prothrombin (p=0.003), and alpha-fetoprotein (AFP) (p=0.024). Patients with high NEK2 expression had significantly poor recurrence-free survival (p=0.042) and early recurrence.\Question: Does high NEK2 Expression be a Predictor of Tumor Recurrence in Hepatocellular Carcinoma Patients After Hepatectomy?
Output (English): Overall, these results suggest that NEK2 could be a promising biomarker for HCC recurrence.
