Stereotactic body radiation therapy and immunotherapy.

Immunotherapy has revolutionized the treatment of various types of cancers in recent years. Since the US Food and Drug Administration approval of the anti-cytotoxic T-lymphocyte-associated antigen 4 agent ipilimumab for late-stage melanoma in 2011, results from multiple clinical trials have proven the benefit of immunotherapy in the treatment of other cancers. However, therapeutic resistance to immunotherapy often develops. This has led investigators to combine immunotherapy with stereotactic body radiation...

Targeting PPAR ligands as possible approaches for metabolic reprogramming of T cells in cancer immunotherapy.

Despite the prominent progress in understanding cancer immunosurveillance mechanisms, there are some types of problems which have been identified to hinder effective and successful immunotherapy of cancers. Such problems have been ascribed to the tumor abilities in the creation of a tolerant milieu that can impair immune responses against cancer cells. In the present study, we represent possible approaches for metabolic reprogramming of T cells in cancer immunotherapy to overcome tumor metabolic impositions...


Normalization Cancer Immunotherapy for Melanoma.

Today, we are witnessing a revolution in the treatment of cancer through the use of immunotherapy. In the last decade, work from many laboratories and clinicians have unequivocally demonstrated that the immune system can eradicate established cancers and enhance patient survival. However, immunotherapies have distinct tumor response-to-toxicity profiles due to distinct mechanisms of action. We have previously termed immunotherapies that activate a general, systemic immune response as "enhancement cancer imm...

Immunological Complexity of the Prostate Cancer Microenvironment Influences the Response to Immunotherapy.

Prostate cancer is one of the most common cancers in men and a leading cause of cancer-related death. Recent advances in the treatment of advanced prostate cancer, including the use of more potent and selective inhibitors of the androgen signaling pathway, have provided significant clinical benefit for men with metastatic castration-resistant prostate cancer (mCRPC). However, most patients develop progressive lethal disease, highlighting the need for more effective treatments. One such approach is immunothe...

Such therapies range from bi...

Cancer immunotherapy: Pros, cons and beyond.

Cancer immunotherapy is an innovative treatment for tumors today. In various experiments and clinical studies, it has been found that immunotherapy does have incomparable advantages over traditional anti-tumor therapy, which can prolong progression-free survival (PFS) and overall survival (OS). However, immunotherapy has obvious complexity and uncertainty. Immunotherapy may also cause severe adverse reactions due to an overactive immune system. More effective and fewer adverse reactions immunological checkp...

To TAP or not to TAP: alternative peptides for immunotherapy of cancer.

Intracellular processing of antigens is crucial for the generation of T cell immunity towards cancers, since cleaved protein products are the molecular targets of these adaptive lymphocytes. The majority of antigenic peptides requires the TAP transporter to gain access to the peptide loading complex in the ER lumen where they bind MHC class I (MHC-I). This pivotal role of TAP in antigen processing makes the system vulnerable for modifications in cancer cells and indeed human cancers frequently silence this ...

Immunotherapy: Checkpoint Inhibitors in Lynch-Associated Gynecologic Cancers.

Research into novel therapies for gynecologic cancers is underfunded, and as a result, we are still playing catchup with other solid tumors in the realm of immune checkpoint inhibition. This is despite the fact that two of the most common gynecologic cancers in the USA have strong biologic rationales for response to these agents. Work is now underway to demonstrate safe and effective therapies for our patients. As we better understand the immune system, and more specifically the tumor microenvironment, we w...

Imaging of T-cells and their responses during anti-cancer immunotherapy.

Immunotherapy has proven to be an effective approach in a growing number of cancers. Despite durable clinical responses achieved with antibodies targeting immune checkpoint molecules, many patients do not respond. The common denominator for immunotherapies that have successfully been introduced in the clinic is their potential to induce or enhance infiltration of cytotoxic T-cells into the tumour. However, in clinical research the molecules, cells and processes involved in effective responses during immunot...

Immunologic Characteristics of Nonmelanoma Skin Cancers: Implications for Immunotherapy.

In this review, we summarize the immunology of nonmelanoma skin cancers (NMSCs) and the clinical data with immunotherapy in this heterogeneous group of cancers that include basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (CSCC), and Merkel cell carcinoma (MCC). NMSCs are exceedingly common, and their treatment consumes substantial health care resources. Annual global mortality from NMSCs is comparable to that from malignant melanoma. Although the majority of NMSCs are localized at diagnosis an...

Immunotherapy in Colorectal Cancer.

Colorectal cancer (CRC) is the third leading cause of cancer deaths, with only 15% of patients surviving 5 years in the metastatic setting. Recent exciting developments in cancer immunotherapy, which involves priming the host's natural immune defenses to recognize, target, and destroy cancer cells effectively, have brought some glimpse of hope in fighting this deadly disease. Although CRC has been shown to evade immune detection like many other cancers do, immunotherapy has been noted to produce some very i...

Repurposing of Cetuximab in antibody-directed chemotherapy-loaded nanoparticles in EGFR therapy-resistant pancreatic tumours.

The anti-Epidermal Growth Factor Receptor (EGFR) antibody Cetuximab (CTX) has demonstrated limited anti-cancer efficacy in cells overexpressing EGFR due to activating mutations in RAS in solid tumours, such as pancreatic cancer. The utilisation of antibodies as targeting components of antibody-drug conjugates, such as trastuzumab emtansine (Kadcyla), demonstrates that antibodies may be repurposed to direct therapeutic agents to antibody-resistant cancers. Here we investigated the use of CTX as a targeting a...

Current Status of Immunotherapy for Lung Cancer and Future Perspectives.

Lung cancer remains the most common cause of cancer-related deaths worldwide. Although there are many possible treatments, including targeted therapies such as epidermal growth factor receptor tyrosine kinase inhibitors and anaplastic lymphoma kinase inhibitors, new therapeutic strategies are needed to improve clinical outcomes. Immunotherapy through the use of immune checkpoint inhibitors has provided one of the most important breakthroughs in the management of solid tumors, including lung cancers, and has...

Immunotherapy-related hepatitis: real-world experience from a tertiary centre.

Immune checkpoint inhibitors like anti-programmed cell death protein 1 (PD-1) drugs Nivolumab and Pembrolizumab and anti-cytotoxic T-lymphocyte associated (CTLA-4) drug Ipilimumab have become standard of care in many metastatic cancers. Immunotherapy-related hepatitis and cholangitis present a diagnostic and management challenge, being rare and incompletely characterised. We aim to report the incidence, features and treatments used for this in a real-world setting and to identify useful biomarkers, which ca...

Perspectives on Recent Progress in Focused Ultrasound Immunotherapy.

Immunotherapy holds tremendous promise as a strategy for eradicating solid tumors. However, poor T cell infiltration and persistence within most solid tumor microenvironments, as well as mechanisms of adaptive resistance, continue to severely limit the accessibility of most immunotherapies to a broad patient population. This limitation perpetuates the demand for allied therapeutic strategies. Among such strategies is focused ultrasound (FUS), a non-invasive, non-ionizing technique for precisely targeted aco...

Neferine induces autophagy-dependent cell death in apoptosis-resistant cancers via ryanodine receptor and Ca-dependent mechanism.

Resistance of cancer cells to chemotherapy is a significant clinical concern and mechanisms regulating cell death in cancer therapy, including apoptosis, autophagy or necrosis, have been extensively investigated over the last decade. Accordingly, the identification of medicinal compounds against chemoresistant cancer cells via new mechanism of action is highly desired. Autophagy is important in inducing cell death or survival in cancer therapy. Recently, novel autophagy activators isolated from natural prod...

Improved Survival with Immunotherapy but Lack of Synergistic Effect with Radiation for Stage IV Melanoma of the Head and Neck.

Prospective randomized studies have demonstrated a survival benefit of immunotherapy in stage IV cutaneous melanoma. Some retrospective studies have hypothesized a synergistic effect of radiation and immunotherapy. Our objective was to identify whether there is a survival benefit for patients treated with radiation and immunotherapy in stage IV cutaneous melanoma of the head and neck (CMHN). The National Cancer Database was used to identify patients with stage IV CMHN between 2012 and 2014. These patients w...
