Nivolumab is a fully human immunoglobulin (Ig) G4 antibody that selectively inhibits the programmed death 1 (PD-1) immune checkpoint molecule, and has recently been launched for the treatment of renal cell cancer (RCC) in Japan. Based on its promising anti-tumor efficacy and manageable safety profile demonstrated in the phase III Checkmate 025 trial, nivolumab therapy is rapidly being introduced in metastatic RCC clinical practice. The phase Ia study of atezolizumab, which is a humanized anti-PD-ligand 1 (PD-L1) monoclonal IgG1 antibody, also demonstrated excellent treatment results...

BACKGROUND: Investigation of brain cancer can detect the abnormal growth of tissue in the brain using computed tomography (CT) scans and magnetic resonance (MR) images of patients. The proposed method classifies brain cancer on shape-based feature extraction as either benign or malignant. The authors used input variables such as shape distance (SD) and shape similarity measure (SSM) in fuzzy tools, and used fuzzy rules to evaluate the risk status as an output variable. We presented a classifier neural network system (NNS), namely Levenberg-Marquardt (LM), which is a feed-forward back-propagation learning algorithm used to train the NN for the status of brain cancer, if any, and which achieved satisfactory performance with 100% accuracy...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has an extremely poor prognosis. For the development of more effective immunotherapies, it is first necessary to elucidate the immunological escape mechanisms. In this study, we applied our recently developed highly sensitive immunostaining method employing fluorescent phosphor-integrated dot (PID) nanoparticles to evaluate the prevalence of programmed death ligand 1 (PD-L1) in patients with PDAC. METHODS: This study included 42 patients with PDAC who underwent pancreatectomy...

BACKGROUND: Although patients with metastatic colorectal cancer (CRC) are often unable to undergo treatment after resection of primary tumors, identifying such patients before surgery is not easy. In this study, we evaluated the association among clinicopathological findings, survival outcomes, and ability to undergo multimodal therapy after primary tumor resection in patients with Stage IV CRC. METHODS: We collected clinicopathological findings and preoperative laboratory data, including carcinoembryonic antigen (CEA) and systemic inflammatory response markers for 92 patients who were treated for Stage IV CRC between 2005 and 2014...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are clinically malignant, having metastatic potential. Histological tumor grade is an accepted indicator of malignant potential, but noninvasive prognostic markers have not yet been identified. This study assessed whether the preoperative neutrophil-to-lymphocyte ratio (NLR) could predict clinical outcomes of PNET patients. METHODS: Fifty-eight patients who underwent curative resection for PNETs between 2001 and 2015 were retrospectively evaluated...

BACKGROUND: The redox regulatory protein, thioredoxin-interacting protein (TXNIP), has been confirmed as an important tumor suppressor gene in various types of human cancers. In previous studies, we found that overexpression of tumor suppressor gene RIZ1 in meningiomas can significantly improve the expression of TXNIP by microarray data analysis. Therefore, we hypothesized that TXNIP was associated with the initiation and progression of meningiomas. METHODS: First, we evaluated the expression of TXNIP and Ki-67 in meningioma tissues from 65 patients using immunohistochemistry...
