BACKGROUND: Hotspot mutations of the oncogenes BRAF and NRAS are the most common genetic alterations in cutaneous melanoma. Specific inhibitors of BRAF and MEK have shown significant survival benefits in large phase III trials. However, the prognostic significance of BRAF and NRAS mutations outside of clinical trials remains unclear. METHODS: The mutational status of BRAF (exon 15) and NRAS (exon 2 and 3) was determined in melanoma samples of 217 patients with pyrosequencing and Sanger sequencing...

Understanding the mechanisms of acquired resistance to anti-PD-1 will allow development of better treatment strategies for cancer patients. This study evaluated potential mechanisms of acquired resistance to anti-PD-1 in longitudinally collected metastatic melanoma patient biopsies. Thirty-four metastatic melanoma biopsies were collected from 16 patients who had initially responded to either anti-PD-1 (n=13) alone or combination of anti-PD-1 and ipilimumab (n=3) and then progressed. Biopsies were taken prior to treatment (PRE, n=12) and following progression of disease (PROG, n=22)...

Oncolytic viruses (OVs) are opening new possibilities in cancer therapy with their unique mechanism of selective replication within tumor cells and triggering of antitumor immune responses. HF10 is an oncolytic herpes simplex virus-1 with a unique genomic structure that has non-engineered deletions and insertions accompanied by frame-shift mutations, in contrast to the majority of engineered OVs. At the genetic level, HF10 naturally lacks the expression of UL43, UL49.5, UL55, UL56, and latency-associated transcripts, and overexpresses UL53 and UL54...

Checkpoint inhibitors are monoclonal antibodies attach to several different receptors on T-cells or tumour cells expressing receptors for cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed death-1 (PD-1) and their ligand (PD-L1). Since 2010, numerous trials on different tumour types have been conducted, which was resulted in these drugs being approved for the treatment of melanoma, lung cancer, Hodgkin's lymphoma and head and neck cancers. Urological cancers, especially urothelial and renal-cell carcinomas, are immunogenic tumours...

Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. Recent advances in the understanding of molecular characteristics helped to determine which tumors are most likely to progress. About 50% of patients carrying genetic alterations such as chromosomal aberrations and mutations are at significant risk for metastatic disease of which the majority will succumb to UM within few months. Currently, there is no effective treatment for metastatic uveal melanoma, and we hope this review will encourage researchers and clinicians to work to find a better standard of care...

Anti-programmed death receptor 1 (PD-1) drugs nivolumab and pembrolizumab were recently approved for the treatment of advanced melanoma and other solid tumors. Atypical patterns of response (i.e. tumor shrinkage or stabilization after initial progression) were observed in about 10% of metastatic melanoma patients treated with anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) drug ipilimumab and were associated with improved survival; however, the rate of atypical response patterns to anti-PD-1 therapy is not clear...

The treatment of metastatic melanoma is still undergoing a process of major change. The two most important novel therapeutic strategies, selective kinase inhibitors and immune checkpoint blockers, both significantly prolong survival times of patients with advanced metastatic disease. Different agents, dose regimens and combinations have been tested against each other vigorously within these two groups. However, results from prospective head-to-head comparative studies of both strategies are still lacking. We performed an exploratory analysis of survival data from selected clinical trials representative for the new treatment strategies in advanced metastatic melanoma...

The first evidence that radiation therapy (RT) enhances the efficacy of immune checkpoint blockers (ICBs) was obtained a dozen years ago in a mouse model of metastatic carcinoma refractory to anti-CTLA-4 treatment. At the time, ICBs had just entered clinical testing, an endeavor that culminated in 2011 with the approval of the first anti-CTLA-4 antibody for use in metastatic melanoma patients (ipilimumab). Thereafter, some patients progressing on ipilimumab showed systemic responses only upon receiving radiation to one lesion, confirming clinically the pro-immunogenic effects of radiation...

BACKGROUND: Metastatic melanoma of unknown primary (MUP) is uncommon, biologically ill defined, and clinically understudied. MUP outcomes are seldom reported in clinical trials. In this study, we analyze responses of MUP patients treated with systemic therapy in an attempt to inform treatment guidelines for this unique population. METHODS: New York University (NYU)'s prospective melanoma database was searched for MUP patients treated with systemic therapy. PubMed and Google Scholar were searched for MUP patients treated with immunotherapy or targeted therapy reported in the literature, and their response and survival data were compared to the MUP patient data from NYU...

Hepatocellular carcinoma (HCC) is an aggressive cancer associated with high mortality worldwide. HCC develops in the setting of underlying cirrhosis due to chronic liver disease. Surgery is usually considered the treatment of choice for early disease; however, most patients have locally advanced or metastatic HCC at diagnosis in which case treatments are limited. Immune checkpoint blockade of programmed death receptor-1 (PD-1) pathway offers a potential treatment strategy based on the encouraging results of the phase I/II trial of nivolumab (Checkmate 040 trial)...

Ipilimumab (Bristol-Myers Squibb Co., New York, NY) is a novel anticancer medication used for the treatment of metastatic melanoma. The exact mechanism of its action remains unclear; however, data from previous clinical trials postulates the immunomodulatory activity of ipilimumab to enhance therapeutic effectiveness. Ipilimumab was approved by the Food and Drug Administration (FDA) in March 2011 for use in stage III and IV of unresectable metastatic melanoma. We report a single case of acute inflammatory demyelinating polyneuroradiculopthy (AIDP) in the patient treated with ipilimumab for recurrent metastatic melanoma...

LESSONS LEARNED: Percutaneous thermal ablation combined with in situ granulocyte-macrophage colony-stimulating factor cytokine therapy was technically feasible and well tolerated.No significant clinical or immunologic responses were seen. BACKGROUND: Melanoma tumor-derived heat-shock proteins (HSPs) and HSP-peptide complexes can elicit protective antitumor responses. The granulocyte-macrophage colony-stimulating factor (GM-CSF) chemokine can also promote uptake and processing by professional antigen presenting cells (APCs)...

Nivolumab, a human IgG4 monoclonal antibody directed against PD-1, is a checkpoint inhibitor that is licenced in the treatment of metastatic melanoma either as a monotherapy or in combination with ipilimumab, a CTLA-4 inhibitor. The introduction of immune checkpoint inhibitors to the therapeutic landscape has dramatically altered outcomes in a proportion of patients with metastatic melanoma. Immune checkpoint inhibitors result in a toxicity profile that is distinct from that of chemotherapy or targeted therapy based on their immunomodulatory mechanism and similarly can result in patterns of response that are unique...

PURPOSE OF REVIEW: The present review will highlight recent advances in the clinical application of oncolytic viral therapy. RECENT FINDINGS: Until recently, oncolytic viral researchers saw the immune system as an enemy that would clear the virus from the bloodstream. However, researchers now understand that sustained responses are seen in those patients with more robust antitumor immune responses. Much of the current focus in oncolytic viral research is trained on manipulation of the immune system to affect cancer cell killing in the tumor microenvironment and to facilitate durable systemic antitumor immunity...

Thanks to striking progress in both the understanding of anti-tumor immune response and the characterization of several tumor associated antigens (TAA), a more rational design and more sophisticated strategies for anti-tumor vaccination have been possible. However, the effectiveness of cancer vaccines in clinical trial is still partial, indicating that additional studies are needed to optimize their design and their pre-clinical testing. Indeed, anti-tumor vaccination success relies on the choice of the best TAA to be targeted and on the translational power of the pre-clinical model used to assess its efficacy...

BACKGROUND: MEK inhibitors are a group of drugs that have shown reliable effects in the treatment of metastatic melanoma and non-small-cell lung cancer. Peripheral edema is an adverse event associated with MEK inhibitors, however, there has been no systematic attempt to evaluate peripheral edema data observed with these agents. This meta-analysis aimed to determine the risk of peripheral edema in cancer patients treated with MEK inhibitors.

BACKGROUND: Antiprogrammed death-1 antibodies (anti-PD1) have response rates of 40% in metastatic melanoma. Patients with poor performance status (PS) were excluded from clinical trials, yet use of anti-PD1 is widespread in clinical practice. Literature regarding clinical and palliative care outcomes in patients with poor PS treated with anti-PD1 is lacking. METHODS: Retrospective review of outcomes for all patients with advanced melanoma treated with anti-PD1 between 2012 and June 2015 at Peter MacCallum Cancer Centre, a tertiary specialist cancer center in Australia...

Although immunomodulating antibodies are highly effective in metastatic melanoma, their toxicity, related to the activation of T lymphocytes, can be severe. Anticancer vaccines promote a fairly specific response and are very well tolerated, but their effectiveness has yet to be demonstrated. We have been treating patients with advanced melanoma with an autologous dendritic cell vaccine since 2001; to better characterize the safety and efficacy of our product, we designed a retrospective study on all of our patients treated with the vaccine to date...
