Y D Seo, V G Pillarisetty
Despite recent advancements in multimodal therapy, pancreatic ductal adenocarcinoma (PDA) continues to have a dismal prognosis. In the era of burgeoning immune therapies against previously difficult-to-treat malignancies, there has been growing interest in activating the immune system against PDA; however, unlike in other cancers such as melanoma and lymphoma, immunotherapy has not yielded many clinically significant results. To harness these mechanisms for therapeutic use, an in-depth understanding of T-cell programming in the immune microenvironment of PDA must be achieved...

Melanoma brain metastases (MBM) occur in 10% to 50% of melanoma patients. They are often associated with a high morbidity and despite the improvements in the treatment of advanced melanoma, including immunotherapy, patients with MBM still have a poor prognosis. Antiangiogenic treatment was shown to reduce the immunosuppressive tumor microenvironment. Therefore we investigated the effect of the combination of VEGFR- and CTLA-4 blockade on the immune cells within the tumor microenvironment. In this study we investigated the effect of the combination of axitinib, a TKI against VEGFR-1, -2 and -3, with therapeutic inhibition of CTLA-4 in subcutaneous and intracranial mouse melanoma models...

Immunotherapies have emerged as one of the most promising approaches to treat patients with cancer. Recently, there have been many clinical successes using checkpoint receptor blockade, including T cell inhibitory receptors such as cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death-1 (PD-1). Despite demonstrated successes in a variety of malignancies, responses only typically occur in a minority of patients in any given histology. Additionally, treatment is associated with inflammatory toxicity and high cost...

BACKGROUND: Cancer patients often report behavioral and cognitive changes following cancer treatment. These effects can be seen in patients who have not yet received treatment or have received only peripheral (non-brain) irradiation. Novel treatments combining radiotherapy (RT) and immunotherapy (IT) demonstrate remarkable efficacy with respect to tumor outcomes by enhancing the proinflammatory environment in the tumor. However, a proinflammatory environment in the brain mediates cognitive impairments in other neurological disorders and may affect brain function in cancer patients receiving these novel treatments...

Immunotherapy is heralded as one of the most important advances in oncology. Until recently, only limited immunotherapeutic options were available in selected immunogenic cancers like melanoma and renal cell carcinomas. Nowadays, there is an improved understanding that anti-tumor immunity is controlled by a delicate balance in the tumor microenvironment between immune stimulatory and immune inhibitory pathways. Either by blocking the inhibitory pathways or stimulating the activating pathways that regulate cytotoxic lymphocytes, anti-tumor immunity can be enhanced leading to durable anti-tumor responses...

Immunomodulatory drugs that leverages host immune mechanisms to destroy tumor cells has been met with great promise in the treatment of cancer. Immunotherapy, targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death 1 (PD-1) receptor and its ligand (PD-L1) have shown tremendous improvements in the survival of patients with advanced solid tumors. However, the development of dermatologic toxicity (DT) is a consequence to immunotherapy. Review of published reports of the DT to immunotherapy revealed patients receiving anti-CTCLA-4 antibody or anti-PD-1/PD-L1 antibody often develop a DT of any type and grade...

The sixth "Melanoma Bridge Meeting" took place in Naples, Italy, December 1st-4th, 2015. The four sessions at this meeting were focused on: (1) molecular and immune advances; (2) combination therapies; (3) news in immunotherapy; and 4) tumor microenvironment and biomarkers. Recent advances in tumor biology and immunology has led to the development of new targeted and immunotherapeutic agents that prolong progression-free survival (PFS) and overall survival (OS) of cancer patients. Immunotherapies in particular have emerged as highly successful approaches to treat patients with cancer including melanoma, non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's disease...

BACKGROUND: The treatment of early or locally advanced stages of non-small cell lung cancer (NSCLC) is based on surgical resection or radiotherapy. Metastatic disease is always incurable, treatment is palliative, systemic based on chemotherapy or target therapy. NSCLC is the most common cause of cancer-related death worldwide, and new therapeutic approaches are needed. Based on the emerging data on the role of immune system in shaping of tumor outbreak and outcome, immunotherapy is currently in the center of interest of cancer research and therapy of solid cancers including NSCLC...

In the past decade, several agents targeting angiogenesis and signal transduction pathways have replaced the use of cytokines as standard of care treatment for metastatic renal cell carcinoma (RCC) after showing improved clinical benefit and survival. Currently, several novel immunotherapy agents targeting the programmed cell death-1 (PD-1) and cytotoxic T-lymphocyte-associated protein-4 (CTLA-4) pathways are being tested in metastatic RCC and are bound to revolutionise the management of this disease. However, the success of both antiangiogenic drugs and new immunotherapy agents still depends on our ability to select patients most likely to respond to treatment...

Pediatric brain and extracranial solid tumors are a diverse group of malignancies that represent almost half of pediatric cancers. Standard therapy includes various combinations of surgery, cytotoxic chemotherapy and radiation, which can be very harmful to a developing child, and survivors carry a substantial burden of long term morbidities. While these therapies have improved survival rates for children with solid tumors, outcomes still remain extremely poor for subsets of patients. Recently, immunosuppressive checkpoint molecules that negatively regulate immune cell function have been described...

While cancer has been traditionally treated by chemotherapy, radiation, targeted therapies and surgery, a fifth pillar of cancer treatment, immunotherapy, has emerged over the past 10 years and revolutionized our war on cancer. The benchmark for drugs in this category has been set by the development of CD8 T cell checkpoint (CTLA-4 and PD-1/PD-L1) inhibitors. These therapies effectively expand and reactivate the pool of tumor-specific T cells leading to objective response rates of up to 50% in patients with certain cancers...

The usual treatments for patients with non-small-cell lung cancer (NSCLC), such as advanced lung adenocarcinoma, are unspecific and aggressive, and include lung resection, radiotherapy and chemotherapy. Recently, treatment with monoclonal antibodies and biological inhibitors has emerged as an effective alternative, generating effective results with few side effects. In recent years, several clinical trials using monoclonal antibodies presented potential benefits to NSCLC, and four of them are already approved for the treatment of NSCLC, such as cetuximab, bevacizumab, nivolumab and pembrolizumab...

We describe "photothermal immunotherapy," which combines Prussian blue nanoparticle (PBNP)-based photothermal therapy (PTT) with anti-CTLA-4 checkpoint inhibition for treating neuroblastoma, a common, hard-to-treat pediatric cancer. PBNPs exhibit pH-dependent stability, which makes them suitable for intratumorally-administered PTT. PBNP-based PTT is able to lower tumor burden and prime an immune response, specifically an increased infiltration of lymphocytes and T cells to the tumor area, which is complemented by the antitumor effects of anti-CTLA-4 immunotherapy, providing a more durable treatment against neuroblastoma in an animal model...

Remarkable clinical responses have been seen in patients with metastatic melanoma with targeted therapy (BRAFi vemurafenib, MEKi) and with modern immune cell-based approaches such as TCR engineered adoptive cell transfer (ACT) and earlier experiences with high-dose IL-2. The proximal mediators of these immune therapies are tumor-reactive CTL. Various mechanisms of resistance to immune-mediated apoptotic signals have been described, including phenotypic changes, effector cell exhaustion, functional tolerance, deficiencies in Ag processing and presentation, and mutation or down-regulation of antigenic epitopes...

Co-inhibitory and co-stimulatory receptors act in concert to regulate adaptive immune cell function, and the balance of these receptors is essential for the maintenance of immune homeostasis. Tumors constitute highly suppressive microenvironments in which elevated expression of co-inhibitory receptors on tumor-infiltrating lymphocytes (TILs) is often found. Functional blockade of the co-inhibitory receptors such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death 1 (PD-1) have yielded encouraging outcomes in tumors, generating substantial interest in seeking for additional co-inhibitory molecules that may act as potential interfering targets...

BACKGROUND: Multiple myeloma is an incurable plasma cell malignancy that is mostly restricted to the bone marrow. Cancer-induced dysfunction of cytotoxic T cells at the tumor site may be responsible for immune evasion and therapeutical failure of immunotherapies. Therefore, enhanced knowledge about the actual status of T cells in myeloma bone marrow is urgently needed. Here, we assessed the expression of inhibitory molecules PD-1, CTLA-4, 2B4, CD160, senescence marker CD57, and CD28 on T cells of naive and treated myeloma patients in the bone marrow and peripheral blood and collected data on T cell subset distribution in both compartments...

Cancer cells express tumour-specific antigens derived via genetic and epigenetic alterations, which may be targeted by T-cell-mediated immune responses. However, cancer cells can avoid immune surveillance by suppressing immunity through activation of specific inhibitory signalling pathways, referred to as immune checkpoints. In recent years, the blockade of checkpoint molecules such as PD-1, PD-L1 and CTLA-4, with monoclonal antibodies has enabled the development of breakthrough therapies in oncology, and four therapeutic antibodies targeting these checkpoint molecules have been approved by the FDA for the treatment of several types of cancer...

  Extensive research over 100 years has clarified that cancers are surely suppressed by human immune system. Unfortunately, a number of clinical trials with various approaches have fallen short of clinical application because of the lack of significant anti-tumor effect. However, recent approved immune checkpoint inhibitors, namely PD-1 and CTLA-4 blockers, provide even better prognosis than existing chemotherapy in patients with certain types of cancer. There is no doubt that immunotherapy is becoming a standard treatment as well as surgery, chemotherapy and radiotherapy...

Besides limited success in treatment of melanoma and renal cell carcinoma, immune treatments of cancer (cancer immunotherapy) had not until recently met the great expectations associated with them over the years. This failure appears now to be reversed with the introduction of checkpoint (immune blockade) inhibitors. Two receptor-ligand checkpoint inhibition pairs, the one based on the inhibition of inhibitory receptor cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and the other based on the inhibition of the programmed death-ligand 1/programmed cell death-1 (PD-L1/PD-1) pair have entered the clinical arena...
