Pembrolizumab, a potent antibody against programmed death 1 (PD-1) receptor, has shown robust antitumor activity and manageable safety in patients with advanced solid tumors. Its pharmacokinetic (PK) properties were analyzed with population PK modeling using pooled data from the KEYNOTE-001, -002, and -006 studies of patients with advanced melanoma, non-small cell lung cancer (NSCLC), and other solid tumor types. Pembrolizumab clearance was low and the volume of distribution small, as is typical for therapeutic antibodies...

BACKGROUND: Pulmonary segmentectomy with radical lymphadenopathy has been considered effective to manage small primary lung cancers [1, 2]. This procedure provides the advantages of minimal invasive surgery and is reported sufficient for safe margin. However, segmentectomy is more difficult to be performed than lobectomy because intersegmental plane cannot be detected easily. Several methods have been reported for identifying the actual intersegmental plane [3-7], but the sensitivity of these methods is limited to the lung conditions like patients with emphysematous lung and needed skilled surgeon to perform...

Hepatocellular cancer (HCC) is increasing dramatically in incidence in Europe and the United States due mainly to the hepatitis C epidemic and, to a lesser extent, increased body mass index of the population. In the fairly recent past, HCC was largely considered as untreatable due to detection mainly at late stages and lack of effective drugs for treatment. Several advances have led to changes in the prognosis of HCC. Screening of high-risk populations has allowed for earlier detection in some studies. If found at an early stage, liver transplantation not only cures the usual underlying cirrhosis but has cure rates for HCC in the range of 60% in recent series...

BACKGROUND: Dermatomyositis (DM) is an autoimmune disease characterized by cutaneous Gottron papules, heliotrope rash, and proximal myopathy. It may also present as a paraneoplastic syndrome that can complicate a variety of different cancers, such as lung, cervical, and breast cancer. However, the association with hepatocellular carcinoma (HCC) is extremely rare. Moreover, to our knowledge, there are no previous reports of colonic perforation following steroid pulse treatment for a DM patient...

Chronic infection by hepatitis C virus (HCV) is a major risk factor for the development of hepatocellular carcinoma (HCC). Despite the clear clinical importance of virus-associated HCC, the underlying molecular mechanisms remain largely unclarified. Oxidative stress, in particular, DNA lesions associated with oxidative damage, plays a major role in carcinogenesis, and is strongly linked to the development of many cancers, including HCC. However, in identifying hepatocytes with HCV viral RNA, estimates of the median proportion of HCV-infected hepatocytes have been found as high as 40% in patients with chronic HCV infection...

Hepatitis B virus X protein (HBx) plays an important role in the development of hepatocellular carcinoma (HCC). In addition, hepatoma upregulated protein (HURP) is a cellular oncogene that is upregulated in a majority of HCC cases. We highlight here recent findings demonstrating a link between HBx, HURP and anti-apoptosis effects observed in cisplatin-treated HCC cells. We observed that Hep3B cells overexpressing HBx display increased HURP mRNA and protein levels, and show resistance to cisplatin-induced apoptosis...

We report a lung transplant recipient who developed BK polyoma virus (BKPyV) DNAemia and BKPyV nephropathy. With careful management of his immunosuppression he achieved significant reduction in BKPyV DNAemia and stabilization of his kidney function. He later developed a high-grade bladder cancer and shortly thereafter he experienced a major upsurge in the level of BKPyV DNAemia that coincided with the discovery of hepatic metastasis. Retrospectively, the bladder cancer and the hepatic secondary tumor stained uniformly for SV40 large T antigen, and the BKPyV DNA sequences identified in plasma corresponded to BKPyV DNA within hepatic tissue, indicating that the spike in BKPyV load was likely derived from the circulating tumor cells or cell-free tumor DNA following metastases of a BKV-associated cancer...

Acute liver disease is characterized by inflammation, oxidative stress and necrosis, which can greatly influence the long term clinical outcome and lead to liver failure or cancer. Here, we initially demonstrated the beneficial role of caspase-9-dependent autophagy in acute liver injury. Treatment with caspase-9 inhibitor z-LEHD-FMK in HepG2 cells, AML12 cells and C57BL/b6N mice exacerbated CCl4-induced acute hepatocellular damage, and also down-regulated autophagy markers expression levels, indicating that caspase-9 inhibition may aggravate acute liver damage by suppressing cytoprotective autophagy...

Upregulated gene 11 (URG11), a new gene upregulated by hepatitis B virus X protein, was found to be involved in the development and progression of several tumors. However, the role of URG11 in human non-small cell lung cancer (NSCLC) has not yet been determined. Therefore, the aim of the present study was to explore the role of URG11 in human NSCLC. Our results found that URG11 was highly expressed in human NSCLC tissues compared with matched normal lung tissues, and higher levels were found in NSCLC cell lines in comparison to the normal lung cell line...

Immunotherapy with checkpoint inhibitors is an effective strategy for several cancers. In some patients long-term remissions are seen. However, enhancement of the immune response can be accompanied by immune-related adverse events (irAEs). These patients often present with nonspecific symptoms. The most common irAEs are dermatitis, colitis, pneumonitis, hepatitis and endocrinopathies. IrAEs can occur in every organ, even simultaneously. Furthermore, irAEs can occur weeks or months after discontinuation of checkpoint inhibitors...

The programmed cell death protein 1 (PD1) is one of the checkpoints that regulates the immune response. Ligation of PD1 with its ligands PDL1 and PDL2 results in transduction of negative signals to T-cells. PD1 expression is an important mechanism contributing to the exhausted effector T-cell phenotype. The expression of PD1 on effector T-cells and PDL1 on neoplastic cells enables tumor cells to evade anti-tumor immunity. Blockade of PD1 is an important immunotherapeutic strategy for cancers. Pembrolizumab (Keytruda) is a humanized monoclonal anti-PD1 antibody that has been extensively investigated in numerous malignancies...

Early detection of hepatocellular carcinoma (HCC) is critical for successful treatment and favorable prognosis. To identify novel HCC biomarkers, we used the WHV/c-myc transgenic (Tg) mice, an animal model of hepatocarcinogenesis. By analyzing their gene expression profiling, we investigated differentially expressed genes in livers of wild-type and Tg mice. The cytochrome P450, family 17, subfamily A, polypeptide 1 (CYP17A1), a hepatic P450 enzyme, was revealed to be overexpressed in the liver tissues of Tg mice at both preneoplastic and neoplastic stages...

Several indices have been proposed to evaluate the systemic inflammatory response (SIR), which has been reported to be a useful prognostic factor in various types of cancer. We investigated the usefulness of the Glasgow Prognostic Score (GPS), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors in patients with advanced hepatocellular carcinoma (HCC) with extrahepatic metastasis (stage IVB). Between April, 1997 and March, 2013, a total of 434 HCC patients who developed extrahepatic metastasis were enrolled in the present study...

Solid organ transplantation has become the therapy of choice for patients with end-stage organ disease. The frequently transplanted organs in Taiwan include liver, kidney, heart, and lung, and the success rate has improved significantly worldwide for the past decades. However, organ recipients are known to be at a higher risk of post-transplant infections and de novo cancer due to immunosuppression and oncogenic viral infections. Organ recipients are known to be at a two- to fourfold increased risk of cancer and the risks are particularly high for malignancies caused by viral infections, including post-transplant lymphoproliferative disorders via Epstein-Barr virus, Kaposi sarcoma via Kaposi sarcoma herpesvirus, anogenital cancers via human papillomavirus, and hepatocellular carcinoma via hepatitis B and C virus...
