BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common cancers in China and frequently occurs with chronic hepatitis B virus infection. To investigate whether cell-based cancer immunotherapy induces tumor specific immune responses in patients with HCC and provides clinical benefits, as well as to elucidate the most immunogenic tumor associated antigens (TAAs), multiple antigen stimulating cellular therapy (MASCT) was applied in addition to standard of care. METHODS: Mature dendritic cells (DCs) and activated T cells prepared for MASCT were generated from autologous peripheral blood mononuclear cells (PBMCs)...

Liver transplant is now an acceptable and effective treatment for specific nonhepatocellular malignancies. Worldwide, hilar cholangiocarcinoma accounts for 3% of all primary gastrointestinal malignancies and for 10% of primary hepatobiliary malignancies. For patients who have early-stage, unresectable cholangiocarcinoma, liver transplant preceded by neoadjuvant radiotherapy can result in tumor-free margins, accomplish a radical resection, and treat the underlying primary sclerosing cholangitis when present...

Antibody-drug conjugates (ADCs) are a promising class of anticancer agents which have undergone substantial development over the past decade and are now achieving clinical success. The development of novel site-specific conjugation technologies enables the systematic study of architectural features within the antibody conjugated drug linker that may affect overall therapeutic indices. Here we describe the results of a systematic study investigating the impact of drug-linker design on the in vivo properties of a series of homogeneous ADCs with a conserved site of conjugation, a monodisperse drug loading, a lysosomal release functionality and monomethyl auristatin E as a cytotoxic payload...

Systemic drug delivery to a solid tumor involves a sequence of steps that determine efficacy and survival. Extravasation from circulation at the tumor site is a critical step in this sequence since it regulates how much of the drug accumulates in the tumor. Despite its importance in determining outcomes, extravasation from circulation remains a "black box." The objective of this study is to develop predictive tools for optimization of drug delivery systems. By comparing pharmacokinetics of liposomal doxorubicin in tumor-free and tumor bearing mice we quantitatively assess the rate constants for distribution, elimination, and tumor accumulation...

BACKGROUND: Nodular fasciitis is a benign reactive proliferative lesion of fibroblast cells, which can occur throughout the body. However, it has rarely been reported in the breast of an elderly woman. CASE PRESENTATION: Our patient was an 88-year-old Asian woman who had noticed a mass in her right breast for 1 month before presentation to our hospital. The mass was elastic-hard and 20 mm in size. No qualitative diagnosis was made by core needle biopsy. Because of potentially malignant findings on mammography and ultrasonography, she underwent an excisional biopsy...

BACKGROUND: The local recurrence rate in oral squamous cell cancer (OSCC) hardly decreases. This is partly due to the presence of (pre)malignant cells in the remaining tissue after resection, that may lead to the development of a new tumor in time. Detection of histologically (pre)malignant cells in the tumor resection margins should predict these patients at risk for recurrence, however this appears to be difficult in routine practice. Purpose of this study was to apply easy-to-use molecular tests for more accurate detection of (pre)malignant cells in histopathologically tumor-free margins, to improve diagnosis of patients at risk...

MicroRNAs, a class of gene expression regulatory non-coding RNAs, participate in the pathogenic mechanisms of gastric cancer which is one of the life-treating cancers. Due to its aberrant expression in some types of human cancer, miR-383 has the value of being investigated in relation to cancer treatment and diagnosis. MiR-383 is placed in intron of SGCZ, a protein-coding gene, which is subject to dysregulation in various diseases. The purpose of the current study was to investigate the contribution of miR-383 to intestinal-type gastric adenocarcinoma tumorigenesis...

IL-6 produced by tumor cells promotes their survival, conferring a poor prognosis in cancer patients. IL-6 also contributes to immunosuppression of CD4+ T cell-mediated antitumor effects. In this study, we focused on the impact of IL-6 trans-signaling mediated by soluble IL-6 receptors (sIL-6R) expressed in tumor-bearing hosts. Higher levels of sIL-6R circulating in blood was observed in tumor-bearing mice, whereas the systemic increase of sIL-6R was not prominent in tumor-bearing mice with myeloid cell-specific conditional deletion of IL-6R even when tumor cells produced sIL-6R...

Tumor-associated or -infiltrating lymphocytes (TALs or TILs) co-express multiple immune inhibitory receptors that contribute to immune suppression in the ovarian tumor microenvironment (TME). Dual blockade of PD-1 along with LAG-3 or CTLA-4 has been shown to synergistically enhance T-cell effector function, resulting in a delay in murine ovarian tumor growth. However, the mechanisms underlying this synergy and the relative contribution of other inhibitory receptors to immune suppression in the ovarian TME are unknown...

GTL001 is a bivalent therapeutic vaccine containing human papillomavirus (HPV) 16 and HPV18 E7 proteins inserted in the Bordetella pertussis adenylate cyclase (CyaA) vector intended to prevent cervical cancer in HPV-infected women with normal cervical cytology or mild abnormalities. To be effective, therapeutic cervical cancer vaccines should induce both a T cell-mediated effector response against HPV-infected cells and a robust CD8(+) T-cell memory response to prevent potential later infection. We examined the ability of GTL001 and related bivalent CyaA-based vaccines to induce, in parallel, effector and memory CD8(+) T-cell responses to both vaccine antigens...

ARQ 087 is a multi-tyrosine kinase inhibitor with potent activity against the FGFR receptor family, currently in Phase I clinical studies for the treatment of advanced solid tumors. The compound has a very safe profile and induces tumor regressions in FGFR-driven models. The feasibility of combining ARQ 087 with chemotherapy was investigated in FGFR deregulated human xenografts. Nude mice were transplanted subcutaneously with H1581, and when tumor masses reached 150 mg, were randomized to receive vehicle, ARQ 087, paclitaxel, carboplatin as single agents or in combination...
