Natural Killer (NK) cells play a critical role against tumor cells in hematological malignancies. Their activating receptors are essential in tumor cell killing. In Multiple Myeloma (MM) patients, NK cell differentiation, activation and cytotoxic potential are strongly impaired leading to MM escape from immune surveillance in tissues and bone marrow. Mechanisms used by MM to affect NK cell functions are mediated by the release of soluble factors, the expression of activating and inhibitory NK cell ligands, and the expression of immune check-point inhibitors...

Conventional therapeutic approaches for advanced prostate cancer - such as androgen deprivation, chemotherapy, radiation - come up often against lack of effectiveness because of possible arising of correlative cancer cell resistance and/or inadequate anti-tumor immune conditions. Whence the timeliness of resorting to immune-based treatment strategies including either therapeutic vaccination-based active immunotherapy or anti-tumor monoclonal antibody-mediated passive immunotherapy. Particularly attractive, as for research studies and clinical applications, results to be the cytotoxic T-lymphocyte check point blockade by the use of anti-CTLA-4 and PD-1 monoclonal antibodies, particularly when combined with androgen deprivation therapy or radiation...

BACKGROUND: A recent clinical trial on the immune check-point inhibitor pembrolizumab demonstrated that microsatellite instability (MSI) is a good biomarker for response to this inhibitor. However, clinicopathological features of advanced colorectal cancer (CRC) with high-frequency MSI (MSI-H) are unclear. PATIENTS AND METHODS: A total of 2,439 surgically resected CRC tissues were analyzed for MSI status, and mutational status of V-Ki-Ras2 Kirsten rat sarcoma 2 viral oncogene homolog (KRAS), neuroblastoma RAS viral oncogene homolog (NRAS) and v-Raf murine sarcoma viral oncogene homolog B (BRAF)...

BACKGROUND Nivolumab is an anti-PD-1 immune checkpoint inhibitor that was recently developed for cancer immunotherapy. In the clinical trials of nivolumab, its adverse effects were reported to be less likely than those of conventional anti-cancer agents; however, after practical clinical distribution, it has come to be known that nivolumab induces various immune-related adverse events. CASE REPORT A 58-year-old male with a recurrence of lung adenocarcinoma was treated with nivolumab. Only four days after the initial administration of nivolumab, the patient presented with unbearable restlessness and distress that was resistant to all therapeutic agents used, and it gradually became worse...

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer deaths worldwide. Sonazoid-enhanced ultrasound and gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced MRI are the most important imaging modalities in diagnosing HCC. There are 2 non-contradictory HCC treatment algorithms in Japan. Hepatic arterial infusion chemotherapy plays an important role in the treatment of advanced HCC with main or branch portal vein invasion. Regorafenib, as a second-line systemic treatment, prolongs survival in patients with intermediate and advanced HCC who progressed on sorafenib...

BACKGROUND: Glioblastoma multiforme (GBM) is the most frequent brain tumor. Despite recent advances in treatment approaches the prognosis remains poor, with a median overall survival of 14.6 months. Immunotherapy is the subject of ongoing research and its benefit is becoming evident in other malignancies. Immune check-points such as cytotoxic T lymphocyte associated antigen 4 (CTLA-4), programmed cell death receptor (PD-1) and indoleamine 2,3-dioxygenase (IDO) reduce immune response. OBJECTIVE: To clarify the role of immune check point inhibitors in GBM management...

The application of nanotechnology to the treatment of cancer or other diseases has been boosted during the last decades due to the possibility to precise deliver drugs where needed, enabling a decrease in the drug's side effects. Nanocarriers are particularly valuable for potentiating the simultaneous co-delivery of multiple drugs in the same particle for the treatment of heavily burdening diseases like cancer. Immunotherapy represents a new concept in the treatment of cancer and has shown outstanding results in patients treated with check-point inhibitors...

Central nervous system (CNS) metastases occur in 30% of patients with advanced non-small cell lung cancer (NSCLC). Localized treatments targeting CNS metastases result in delays in systemic therapy administration and are associated with neurocognitive impairment. Nivolumab is an immune check-point inhibitor that is approved as a second-line treatment of NSCLC. Data regarding the intracranial activity of nivolumab is lacking. We retrospectively reviewed the efficacy and safety of nivolumab in five patients with advanced NSCLC and new/progressing intracranial metastases...

The microenvironment of follicular lymphoma (FL) is composed of tumor-infiltrating CD8(+) T cells, follicular regulatory T cells, lymphoma-associated macrophages and mast cells, follicular helper T cells, follicular dendritic cells, and follicular reticular cells, all of which have been reported to have relevance in the prognosis of FL patients. In addition, some of these cells play a role in the histologic transformation of FL. Macrophages contribute to a poor prognosis in FL patients treated in the pre-rituximab era, but are associated with good prognosis in those treated in the rituximab era...

Anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) and anti-programmed cell death-1 (PD-1) inhibitors have been shown to significantly improve survival in patients with metastatic cutaneous melanoma. However, there was some heterogeneity as well as some variation in the degree of benefit across studies. We reviewed randomized trials and performed a meta-analysis to determine the efficacy and safety of immune checkpoint inhibitors in comparison with conventional regimens. Eligible studies were limited to randomized controlled trials comparing anti-CTLA-4 or anti-PD-1 inhibitors to chemotherapy or vaccination treatment in adult patients with unresectable cutaneous metastatic melanoma...

The combination of immune checkpoint inhibitors ipilimumab and nivolumab has been recently been FDA approved for first line treatment of unresectable and metastatic BRAF wild type melanoma. The approval came following the impressive results of the CheckMate 067, where the combination of ipilimumab and nivolumab appeared to outperform each as a single agent in regards to response rate and progression free survival. Though we await final overall survival data, the combination will likely be adapted by many oncologists and integrated into the ever changing melanoma treatment algorithm...

The immune system plays an active role in the pathogenesis of ovarian cancer (OC), as well as in the mechanisms of disease progression and overall survival (OS). Immunotherapy in gynecological cancers could help to revert immunosuppression and lymphocyte depletion due to prior treatments. Current immunotherapies for ovarian cancer, like all cancer immunotherapy, are based on either stimulating the immune system or reverting immune suppression. Several approaches have been used, including therapeutic vaccines, monoclonal antibodies; checkpoint inhibitors and adoptive T cell transfer...

Inhibitors of immune check-point molecule, programmed cell death 1 (PD-1) and its ligand, programmed cell death ligand 1 (PD-L1) have attracted much attention in cancer immunotherapy recently due to their durable antitumor effects in various malignances, especially the advanced ones. Unfortunately, only a fraction of patients with advanced tumors could benefit from anti-PD-1/PD-L1 therapy, while others still worsened. The key to this point is that there are no efficient biomarkers for screening anti-PD-1/PD-L1-sensitive patients...

Immunologic tolerance to cancer has recently been shown to have major implications for the ability of tumors to survive despite a variety of therapeutic approaches. A critical mechanism underlying this microenvironment dysfunction relates to the ability of tumor cells to block immune check points through expression of specific proteins that interfere with immune cell effector function. Recent advances based on this model have led translational work showing therapeutic efficacy in a variety of solid and lymphoid tumors...
