BACKGROUND Despite the increased rate of complete response to initial chemotherapy, most patients with advanced ovarian cancer relapse and succumb to progressive disease. Dendritic cell (DC)-based immunotherapy has been developed as a novel strategy for generating antitumor immunity as part of cancer treatments. The present study aimed to assess the(More)
OBJECTIVES In the current study, we have evaluated the clinical and immunological responses in patients with advanced pancreatic carcinoma who received dendritic cell (DC)-based immunotherapy in combination with gemcitabine and/or S-1. METHODS Dendritic cell-based immunotherapy (DC vaccine alone or DC vaccine plus lymphokine-activated killer [LAK] cell(More)
OBJECTIVE Dendritic cell (DC)-based cancer vaccines may have a significant benefit to patients with advanced pancreatic cancer. However, variations among clinical studies make it difficult to compare clinical outcomes. Here, we identified factors that determined the clinical benefits by analyzing data obtained at seven Japanese institutions that employed(More)
BACKGROUND The streptococcal agent OK-432 has been used for immunotherapy of head and neck cancer, among other malignancies, but its mechanism of action is unknown. Because the Toll-like receptor 4 (TLR4)/MD-2 complex is important in enabling the mammalian immune system to recognize bacterial components, we investigated whether expression of the TLR4 and(More)
It is important to augment the anti-cancer host response in cancer treatment. Recent studies suggested that the signaling via Toll-like receptors (TLRs) which are newly identified receptor molecules recognizing many pathogens, are involved in the induction of anti-cancer immunity. Seya et al. demonstrated that maturation of dendritic cells (DCs) and(More)
A lipoteichoic acid-related molecule OK-PSA is an active component of OK-432, a Streptococcus-derived anticancer immunotherapeutic agent. In the present study, we first examined the effect of OK-PSA on the maturation of dendritic cells (DCs) in vitro by using the DCs derived from 5 healthy donors and 10 patients with head and neck cancer with or without(More)
PURPOSE Dendritic cell (DC)-based vaccines have been expected to serve as new therapeutic approaches for advanced non-small cell lung cancers (NSCLCs); however, their clinical outcomes have not been fully elucidated. We report a single-centre clinical study analysing factors affecting the survival of patients with advanced NSCLCs who received DC vaccines(More)
The European Union's Harmonized Index of Consumer Prices (HICP) is the single most important indicator of inflation used by the European Central Bank. This paper investigates the methodological foundations of the HICP. Sections 2 to 4 of the paper look at the theory of inflation indexes that could be used as central bank target indexes of inflation. A(More)
BACKGROUND We previously reported a phase I study of a cancer vaccine using five novel HLA-A*2402-restricted peptides, and demonstrated the safety and the promising potential of our five-peptide cocktail for advanced colorectal cancer. The objective of this analysis was to investigate predictive biomarkers for the prior selection of patients who are likely(More)
The authors investigated the in vivo anti-tumor effect of intratumoral administration of bone marrow-derived dendritic cells (DCs) after chemotherapy using an oral fluoropyrimidine anti-cancer drug TS-1, and followed by immunotherapeutic agent OK-432, in two syngeneic tumor-bearing mouse models. Both in Meth-A fibrosarcoma-bearing BALB/c mice and in(More)
