Abstract
Purpose The controlling nutritional status (CONUT) score has been reported to predict outcomes in patients with hepatocellular carcinoma (HCC). However, the prognostic significance of the CONUT score in patients with non-B non-C (NBNC) HCC remains to be established. Methods The study comprised 246 patients who had undergone elective hepatic resection for HCC between April 2003 and October 2017. We retrospectively investigated the relation between preoperative CONUT score as well as clinicopathological characteristics and disease-free survival (DFS) as well as overall survival (OS). Results In univariate analyses, CONUT score was associated with DFS and OS in patients with NBNC-HCC (p <= 0.01), while there was no significant association of CONUT score with DFS and OS in patients with HBV- and HCV-related HCC (p >= 0.1). Of the 111 patients with NBNC-HCC, 97 (87.4%) had CONUT score <= 3 (low CONUT score) and the other 14 (12.6%) had CONUT score >= 4 (high CONUT score). In the patients with NBNC-HCC, multivariate analysis identified age >= 65 years (p= 0.03), multiple tumors (p< 0.01), and high CONUT score (p= 0.03) as the independent and significant predictors of DFS, while multiple tumors (p= 0.01), microvascular invasion (p< 0.01), and high CONUT score (p= 0.01) were the independent and significant predictors of OS. Conclusions The CONUT score seems to be a reliable and independent predictor of both DFS and OS after hepatic resection for NBNC-HCC.

Abstract
Oncogenic viruses are among the apparent causes of cancer-associated mortality. It was estimated that 12% to 15% of human malignancies are linked to oncoviruses. Although modernist strategies and traditional genetic studies have defined host-pathogen interactions of the oncoviruses, their host functions which are critical for the establishment of infection still remain mysterious. However, over the last few years, it has become clear that infections hijack and modify cellular pathways for their benefit. In this context, we constructed the virus-host protein interaction networks of seven oncoviruses (EBV, HBV, HCV, HTLV-1, HHV8, HPV16, and HPV18), and revealed cellular pathways hijacking as a result of oncogenic virus infection. Several signaling pathways/processes such as TGF-beta signaling, cell cycle, retinoblastoma tumor suppressor protein, and androgen receptor signaling were mutually targeted by viruses to induce oncogenesis. Besides, cellular pathways specific to a certain virus were detected. By this study, we believe that we improve the understanding of the molecular pathogenesis of viral oncogenesis and provide information in setting new targets for treatment, prognosis, and diagnosis.
