Bruton's tyrosine kinase (BTK) is a non-receptor intracellular kinase that belongs to the TEC-family tyrosine kinases together with bone marrow-expressed kinase (BMX), redundant-resting lymphocyte kinase (RLK), and IL-2 inducible T-Cell kinase (ITK). All these proteins play a key role in the intracellular signaling of both B and T lymphocytes. Recently, some preclinical data have demonstrated that BTK is present in certain tumor subtypes and in other relevant cells that are contributing to the tumor microenvironment such as dendritic cells, macrophages, myeloid derived suppressor cells and endothelial cells...

Resistance to targeted therapy is an ongoing problem for the successful treatment of Stage IV metastatic melanoma. For many patients, the use of targeted therapies, such as BRAF kinase inhibitors, were initially promising yet resistance inevitably occurred. Even after combining BRAF kinase inhibitors with MEK pathway inhibitors to offset re-activation of the MAP kinase pathway, resistance is still documented. Similarly, outcomes with immune checkpoint inhibitors as monotherapy were optimistic for some patients without relapse or progression, yet the majority of patients undergoing monotherapy have progressive disease...

Cancer immunotherapy for urological tumors had made progress for several decades, but recent advances in immunotherapy, as therapeutic vaccines or immune checkpoint inhibitors, have drastically changed the present treatment strategy. Recently, nivolumab and atezolizumab have been approved by the Food and Drug Administration for treatment of urological cancers. Additional immune checkpoint inhibitors and vaccines are being tested in clinical trials. Despite advances in these therapeutic modalities, benefits are limited to a subset of patients...

Prostate cancer is the most common cancer in men, and the second leading cause of cancer-related death in Western countries. Prostate cancer-related death occurs in patients with metastatic castration-resistant prostate cancer. Although several new drugs for castration-resistant prostate cancer have been approved, each of these has prolonged survival by just a few months. Consequently, new therapies are sorely needed. Recently, it has been recognized that immunotherapy is an effective treatment for prostate cancer patients...

Anti-tumor immunity is a new line of research for the treatment of patients with solid tumors. In this field, negative regulators of the immune system called immune checkpoints play a key role in limiting antitumor immunologic responses. For this reason, immune checkpoint-inhibiting agents, such as those directed against cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed death-1 receptor (PD1) and its ligand PD-L1, have been developed as antitumor drugs, producing interesting results in preclinical and clinical studies...

Oncolytic viruses (OV) represent a promising strategy to augment the spectrum of cancer therapeutics. For efficacy, they rely on two general mechanisms: tumor-specific infection/cell-killing, followed by subsequent activation of the host's adaptive immune response. Numerous OV genera have been utilized in clinical trials, ultimately culminating in the 2015 Food and Drug Administration approval of a genetically engineered herpes virus, Talminogene laherparepvec (T-VEC). It is generally accepted that OV as monotherapy have only modest clinical efficacy...

Purpose: Novel partners for established immune checkpoint inhibitors in the treatment of cancer are needed to address the problems of primary and acquired resistance. The efficacy of combination RANKL and CTLA4 blockade in anti-tumor immunity has been suggested by recent case reports in melanoma. Here we provide a rationale for this combination in mouse models of cancer. <br />Experimental Design: The efficacy and mechanism of a combination of RANKL and CTLA4 blockade was examined by tumor infiltrating lymphocyte analysis, tumor growth and metastasis using a variety of neutralizing antibodies and gene-targeted mice...

Background: Immune checkpoint inhibitors improve outcomes compared to chemotherapy in lung cancer. Tumor PD-L1 receptor expression is being studied as a predictive biomarker. The objective of this study was to assess the cost-effectiveness and economic impact of second-line treatment with nivolumab, pembrolizumab, and atezolizumab with and without the use of PD-L1 testing for patient selection. Design: We developed a decision-analytic model to determine the cost-effectiveness of PD-L1 assessment and second-line immunotherapy versus docetaxel...

Perioperative chemotherapy is likely to improve survival in both the neoadjuvant and the adjuvant setting. Therefore, it is an integral part of the modern treatment of patients with muscle-invasive urothelial bladder cancer. All patients who are suitable for cisplatin-based chemotherapy should be involved in a corresponding concept.Cisplatin-based combinations are standard regimens in the perioperative and palliative systemic treatment of urothelial cancer. Carboplatin is only an inferior substitute for "unfit" patients in the palliative treatment situation...

Cytokine-Induced killer (CIK) cells are raising growing interest in cellular antitumor therapy, as they can be easily expanded with a straightforward and inexpensive protocol, and are safe requiring only GMP-grade cytokines to obtain very high amounts of cytotoxic cells. CIK cells do not need antigen-specific stimuli to be activated and proliferate, as they recognize and destroy tumor cells in an HLA-independent fashion through the engagement of NKG2D. In several preclinical studies and clinical trials, CIK cells showed a reduced alloreactivity compared to conventional T cells, even when challenged across HLA-barriers; only in a few patients, a mild GVHD occurred after treatment with allogeneic CIK cells...

Immunotherapy has become a new modality of cancer treatment, but has had a limited success in treating PDAC. A combination approach to immunotherapy, using both immune checkpoint inhibitors and immune activating agonists, is needed, as PDAC does not respond to single-agent checkpoint inhibitors. Studies have also supported using vaccine-based therapies to prime the tumor microenvironment of PDAC with effector T-cells. Other therapeutic strategies including epigenetic agents, stroma modulators, radiotherapy, and T-cell transfer therapies may also prime the tumor microenvironment to overcome resistance to immune checkpoint inhibitors...

Patients with resected stage II or III melanoma are at high risk of recurrence, with 5-year mortality rate of 40-60%. Adjuvant interferon-alfa has demonstrated a small RFS and OS benefit versus observation in this patient population. However, the adjuvant treatment landscape is evolving rapidly. Areas covered: This review aims to summarize the safety and efficacy profiles of adjuvant IFNα/PEG-IFNα, revisit the controversy surrounding its application, and reappraise its position in the rapidly changing treatment landscape of resected melanoma...

Leptomeningeal metastasis (LM) is reported in 3.8% of non-small-cell lung cancer (NSCLC) patients, more frequently in adenocarcinoma, and it correlates with poor prognosis. Data regarding the activity of immune checkpoint inhibitors in LM is lacking. We present a case report about the efficacy of nivolumab in a patient with advanced NSCLC and symptomatic LM.

Lung cancer is the leading cause of cancer-related death worldwide. The most common type, non-small cell lung cancer (NSCLC), is further divided into two main types, squamous cell and non-squamous cell (which includes adenocarcinoma). Nivolumab, a fully human IgG4 programmed death-1 immune checkpoint inhibitor antibody, has shown not only an overall survival advantage when compared to docetaxel, but also a relatively good side-effect profile among patients with previously treated advanced squamous and non-squamous NSCLC...

Immune checkpoint inhibitors, notably antibodies targeting programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1), have modified the management of patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). Several PD-1/PD-L1 inhibitors have been approved by health authorities for this indication and others are in clinical development. However, only a subset of patients truly benefits from these agents. For patients with mutated EGFR or translocated ALK NSCLC, for whom an immune checkpoint inhibitor can be prescribed after progression on tyrosine kinase inhibitors and chemotherapy, information is scarce and sometimes contradictory...

Despite recent advances in treatment for melanoma patients through using immune checkpoint inhibitors, these monotherapies have limitations and additional treatments have been explored. Type I IFNs have been used to treat melanoma and possess immunomodulatory effects including enhancement of T-cell infiltration. T-cell plays a critical role in immune checkpoint therapies via restoration of effector functions and tumor infiltration by T-cells predicts longer survival in a variety of cancer types. Moreover, tumor-infiltrating T-cells are associated with the expression of chemokines such as CCL5 and CXCR3 ligands in tumor tissues...

The use of cytotoxic and/or targeted agents is the gold standard in first- and second-line treatment of metastatic head and neck cancer. Currently the focus of oncologic research is shifting to the implementation of immune checkpoint inhibitor regimens. Many trials are being performed evaluating the survival benefit of various PD-1/PD-L1 blocking antibodies in both solid and haematological malignancies. Also, evaluation of the predictive value of PD-L1 expression on tumour cells and immune cells is being explored...

Immune checkpoint inhibitors (ICI) have shown great promise in a wide spectrum of adult solid and hematological malignancies, achieving objective tumor responses and prolonging survival. However, there is limited clinical success amongst pediatric patients. In this review, we summarize the current understanding of ICI and present an up-to-date overview of recent and ongoing clinical trials of ICI in pediatric malignancies. In addition, we will discuss immunologic and clinical difficulties in this young population, as well as future prospects for combination of ICI with other immune-based and conventional treatments...
