PURPOSE OF REVIEW: Cardiotoxicity is an important complication of cancer therapy. With a significant improvement in the overall survival and prognosis of patients undergoing cancer therapy, cardiovascular toxicity of cancer therapy has become an important public health issue. Several well-established as well as newer anticancer therapies such as anthracyclines, trastuzumab, and other HER2 receptor blockers, antimetabolites, alkylating agents, tyrosine kinase inhibitors, angiogenesis inhibitors, checkpoint inhibitors, and thoracic irradiation are associated with significant cardiotoxicity...

Angiogenesis is defined as the formation of new blood vessels from preexisting vessels and has been characterized as an essential process for tumor cell proliferation and viability. This has led to the development of pharmacological agents for anti-angiogenesis to disrupt the vascular supply and starve tumor of nutrients and oxygen, primarily through blockade of VEGF/VEGFR signaling. This effort has resulted in 11 anti-VEGF drugs approved for certain advanced cancers, alone or in combination with chemotherapy or other targeted therapies...

Advances in cancer immunotherapy have offered new hope for patients with metastatic disease. This unfolding success story has been exemplified by a growing arsenal of novel immunotherapeutics, including blocking antibodies targeting immune checkpoint pathways, cancer vaccines, and adoptive cell therapy (ACT). Nonetheless, clinical benefit remains highly variable and patient-specific, in part, because all immunotherapeutic regimens vitally hinge on the capacity of endogenous and/or adoptively transferred T-effector (Teff) cells, including chimeric antigen receptor (CAR) T cells, to home efficiently into tumor target tissue...

PURPOSE OF REVIEW: Currently, our ability to accurately predict a patient's risk of developing severe gastrointestinal toxicity from their cancer treatment is limited. Risk stratification continues to rely on traditional patient-related and treatment-related factors including age, ethnicity, sex, comorbidities, genetics, agent, dose and schedule. Although informative, these crude measures continue to underestimate toxicity risk, and hence alternative methods of risk prediction must be investigated...

Primary central nervous system lymphoma (PCNSL) is an extra-nodal non-Hodgkin lymphoma. PCNSL is defined as lymphoma involving the brain, leptomeninges, eyes, or spinal cord without evidence of lymphoma outside the CNS. Treatment includes induction with chemotherapy and consolidation with whole-brain radiotherapy or high-dose chemotherapy supported by autologous stem cell transplantation. High-dose methotrexate is the most important drug in cases with PCNSL, and this drug will be used in combination with small molecules, BTK inhibitors, new monoclonal antibodies, and checkpoint blockers...

Many new or relatively new cancer drugs-personalized anticancer agents-have been approved for use in various clinical settings in oncology or are still under evaluation in clinical trials. Targeted therapies as well as new immune checkpoint blockers have toxicity profiles that differ from conventional cytotoxic chemotherapy, and many can cause adverse effects that affect the mouth and pharynx, the nasal cavities, and the larynx. This review aims to provide an overview of current knowledge concerning these side effects and contemporary management...

Cancer immunotherapy has produced impressive clinical results in recent years. Despite the success of the checkpoint blockade strategies targeting cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed death receptor 1 (PD-1), a large portion of cancer patients have not yet benefited from this novel therapy. T cell immunoglobulin and mucin domain 3 (TIM-3) has been shown to mediate immune tolerance in mouse models of infectious diseases, alloimmunity, autoimmunity, and tumor Immunity. Thus, targeting TIM-3 emerges as a promising approach for further improvement of current immunotherapy...

Immune checkpoint blockades induced by antibodies are revolutionizing cancer therapy. Combinations of checkpoint immunotherapies with kinase inhibitors (KIs) are being clinically evaluated as oncogenic mutations arise. Off-target KI cross-reactivity will often compromise synergistic efficacy, with KIs suppressing T-cell functionalities that checkpoint blockers are purportedly boosting. This incompatibility may be removed through molecular optimization.

The use of antibodies to target immune checkpoints, particularly PD-1/PD-L1, has made a profound impact in the field of cancer immunotherapy. Here, we identified KN035, an anti-PD-L1 nanobody that can strongly induce T-cell responses and inhibit tumor growth. The crystal structures of KN035 complexed with PD-L1 and free PD-L1, solved here at 1.7 and 2.7 Å resolution, respectively, show that KN035 competes with PD-1 (programmed death protein 1) for the same flat surface on PD-L1, mainly through a single surface loop of 21 amino acids...

Immunotherapy with immune checkpoint blockers such as the CTLA-4 antibody ipilimumab and PD-1 antibodies has revolutionized oncological treatment options(1) . MCC is an immunogenic tumor and the efficacy of PD-1 blockade has recently been demonstrated(2,3,4) . Here, we present a retrospective analysis of five patients with metastatic MCC individually treated with ipilimumab between 2012 and 2015. Administration of four cycles (3 mg/kg every three weeks) was planned. Informed consent was obtained from all patients...

Newly available immune checkpoint blockers (ICBs), capable to revert tumor immune tolerance, are revolutionizing the anticancer armamentarium. Recent evidence also established that ionizing radiation (IR) could produce antitumor immune responses, and may as well synergize with ICBs. Multiple radioimmunotherapy combinations are thenceforth currently assessed in early clinical trials. Past examples have highlighted the need for treatment personalization, and there is an unmet need to decipher immunological biomarkers that could allow selecting patients who could benefit from these promising but expensive associations...

Uveal melanoma (UM), a rare cancer of the eye, is distinct from cutaneous melanoma by its etiology, the mutation frequency and profile, and its clinical behavior including resistance to targeted therapy and immune checkpoint blockers. Primary disease is efficiently controlled by surgery or radiation therapy, but about half of UMs develop distant metastasis mostly to the liver. Survival of patients with metastasis is below 1 year and has not improved in decades. Recent years have brought a deep understanding of UM biology characterized by initiating mutations in the G proteins GNAQ and GNA11...

Although anticancer therapy with immune checkpoint blockers has seen unprecedented success, it fails to control neoplasia in most patients and often causes immune-related adverse events (irAEs). Our recent research shows the immunostimulatory and antitumor effects of CTLA-4 blockade depend on distinct Bacteroides species of the gut microbiota, signifying novel approaches to improve such immunotherapies.

The immunosuppressive action of regulatory T (Treg) cells is one mechanism attributed to the limited success of cancer immunotherapies with checkpoint blockers. Two recent studies report distinct transcriptional profiles of tumor-infiltrating Treg cells and expression of specific molecules, suggesting novel strategies to overcome resistance to cancer immunotherapy.

Current criteria for identifying cancer patients suitable for immunotherapy with immune checkpoint blockers (ICBs) are subjective and prone to misinterpretation, as they mainly rely on the visual assessment of CD274 (best known as PD-L1) expression levels by immunohistochemistry (IHC). To address this issue, we developed a RNA sequencing (RNAseq)-based approach that specifically measures the abundance of immune transcripts in formalin-fixed paraffin embedded (FFPE) specimens. Besides exhibiting superior sensitivity as compared to whole transcriptome RNAseq, our assay requires little starting material, implying that it is compatible with RNA degradation normally caused by formalin...

  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...

PURPOSE OF REVIEW: Tumors contain not only cancer cells but also nontransformed types of cells, the stromal cells. A bidirectional interplay exists between transformed and nontransformed cells leading to tumor progression and metastasis. Tumor-associated macrophages (TAMs) are the most abundant tumor-infiltrating leukocytes characterized by a high heterogeneity and plasticity. TAMs exhibit strong protumoral activities and are related to bad prognosis and worse overall survival in various cancer types...

With the recent development of novel molecular targeted drugs for advanced stage malignant melanoma (MM), including RAF and mitogen-activated protein kinase kinase inhibitors and immune checkpoint blockers, the early detection of relapse is important for managing patients with MM. In this study, we retrospectively analyzed two conventional serum biomarkers, 5-S-cysteinyl-dopa and lactate dehydrogenase, in patients with MM (n = 140) who were treated at a single Japanese institute from June 2007 to June 2015...

Malignant cells succumbing to some forms of radiation therapy are particularly immunogenic and hence can initiate a therapeutically relevant adaptive immune response. This reflects the intrinsic antigenicity of malignant cells (which often synthesize a high number of potentially reactive neo-antigens) coupled with the ability of radiation therapy to boost the adjuvanticity of cell death as it stimulates the release of endogenous adjuvants from dying cells. Thus, radiation therapy has been intensively investigated for its capacity to improve the therapeutic profile of several anticancer immunotherapies, including (but not limited to) checkpoint blockers, anticancer vaccines, oncolytic viruses, Toll-like receptor (TLR) agonists, cytokines, and several small molecules with immunostimulatory effects...
