While treating stage III melanoma patients with autologous therapeutic TIL in an adjuvant setting, we previously reported a significant benefit of treatment on both progression-free survival and overall survival in patients with only one invaded lymph node (early stage III) compared to patients with more than one invaded lymph nodes (advanced stage III). In this context, in order to understand the difference of activity of TIL therapy according to the progression of the illness at stage III, the first objective of the present study was to determine potential differences in the characteristics of TIL populations obtained from an early stage III and a more advanced stage III when tumor burden is more important. The second objective was to determine possible differences in tissue expression level of several molecules involved in interactions between tumor cells and T cells between early and advanced stage III considering that the tumor microenvironment of invaded lymph nodes could become more tolerant with the progression of the disease. A total of 47 samples of melanoma invaded LN from stage IIIb (AJCC 2007) melanoma patients treated with TIL plus IL-2 were included in this study. We confirmed that both PFS and OS were significantly associated to the presence of tumor-reactive T-cells among TIL injected to the patients and that these tumor reactive T cells were more frequently observed at the early stage III. Moreover, while analyzing the expression of 17 markers on 34/47 tumor specimens using immunohistochemistry, we identified that 3 tissue markers involved in interactions between melanoma cells and T cells have a significant difference of expression between early and advanced stage III: MHC class I, adhesion molecule ICAM-1 and the co-stimulation molecule LFA-3 had a significantly weaker expression in melanoma tissue specimens from advanced stage III. In addition, the expression of the alpha chain of the IL-2 receptor (CD25) and the nuclear transcription factor

Uveal melanoma is the most common intraocular malignancy although it is a rare subset of all melanomas. Uveal melanoma has distinct biology relative to cutaneous melanoma, with widely divergent patient outcomes. Patients diagnosed with a primary uveal melanoma can be stratified for risk of metastasis by cytogenetics or gene expression profiling, with approximately half of patients developing metastatic disease, predominately hepatic in location, over a 15-yr period. Historically, no systemic therapy has been associated with a clear clinical benefit for patients with advanced disease, and median survival remains poor. Here, as a joint effort between the Melanoma Research Foundation's ocular melanoma initiative, CURE OM and the National Cancer Institute, the current understanding of the molecular and immunobiology of uveal melanoma is reviewed, and on-going laboratory research into the disease is highlighted. Finally, recent investigations relevant to clinical management via targeted and immunotherapies are reviewed, and next steps in the development of clinical therapeutics are discussed. © 2014 John Wiley & Sons A/S.

Treating advanced or recurrent melanoma remains a challenge. Cancer cells can evade the immune system by blocking T-cell activation through overexpression of the inhibitory receptor programmed death 1 (PD-1) ligands. The PD-1 inhibitor nivolumab blocks the inhibitory signal in T cells, thus overcoming the immune resistance of cancer cells. Nivolumab has shown promising anticancer activity in various cancers. We carried out a single-arm, open-label, multicenter, phase II study to investigate the efficacy and safety of nivolumab in previously untreated Japanese patients with advanced melanoma. Twenty-four patients with stage III/IV or recurrent melanoma were enrolled and received i.v. nivolumab 3 mg/kg every 2 weeks until disease progression or unacceptable toxicity. The primary endpoint was overall response rate evaluated by an independent radiology review committee. The independent radiology review committee-assessed overall response rate was 34.8% (90% confidence interval, 20.8-51.9), and the overall survival rate at 18 months was 56.5% (90% confidence interval, 38.0-71.4). Treatment-related adverse events (AEs) of grade 3 or 4 only occurred in three patients (12.5%). Two patients discontinued nivolumab because of AEs, but all AEs were considered manageable by early diagnosis and appropriate treatment. Subgroup analyses showed that nivolumab was clinically beneficial and tolerable regardless of BRAF genotype, and that patients with treatment-related select AEs and with vitiligo showed tendency for better survival. In conclusion, nivolumab showed favorable efficacy and safety profiles in Japanese patients with advanced or recurrent melanoma, with or without BRAF mutations. (Trial registration no.

The arrival of targeted therapies has led to significant improvements in clinical outcomes for patients with BRAFV600 mutated advanced melanoma over the past five years. In several clinical trials, BRAF and MEK inhibitors have shown improvement in progression free and overall survival, along with much higher tumor response rates in comparison to chemotherapy, with the combination of these drugs superior to monotherapy. These agents are also being tested in earlier-stage patients, in addition to alternative dosing regimens and in combinations with other therapeutics. Efforts are also ongoing to expand the success found with targeted therapies to other subtypes of melanoma, including NRAS and c-kit mutated melanomas, uveal melanomas, and BRAF/NRAS wild type melanomas. Expert Commentary: We aim to provide an overview of clinical outcomes with targeted therapies in melanoma patients.

Skin cancer affects more individuals in the USA than any other malignancy and malignant melanoma is particularly deadly because of its metastatic potential. Melanoma has been recognized as one of the most immunogenic malignancies; therefore, understanding the mechanisms of tumor-immune interaction is key for developing more efficient treatments. As the tumor microenvironment shows an immunosuppressive action, immunotherapeutic agents promoting endogenous immune response to cancer have been tested (interleukin-2, anticytotoxic-T-lymphocyte-associated antigen 4, and antiprogrammed cell death protein 1 monoclonal antibodies) as well as combinations of cytotoxic chemotherapy agents and inhibitors of angiogenesis (taxol/carboplatin/avastin). However, clinical outcomes are variable, with only a minority of patients achieving durable complete responses. The variability of immune homeostasis, which may be more active or more tolerant at any given time, in cancer patients and the interaction of the immune system with the tumor could explain the inconsistency in clinical outcomes among these patients. Recently, the role of the lymphocyte-to-monocyte-ratio (LMR) in the peripheral blood has been investigated and has been proven to be an independent predictor of survival in different hematological malignancies and in solid tumors. In melanoma, our group has validated the significance of LMR as a predictor of relapse after resection of advanced melanoma. In this study, we examined the dynamics in the immune system of patients with advanced melanoma by performing serial multiday concentration measurements of cytokines and immune cell subsets in the peripheral blood. The analysis of outcomes of chemotherapy administration as related to LMR on the day of treatment initiation showed that progression-free survival was improved in the patients who received chemotherapy on the day when LMR was elevated.

Immunotherapy has become a promising modality for melanoma, especially using checkpoint inhibitors, which revive suppressed T cells against the cancer. Such inhibitors should work better when combined with other treatments which could increase the number and quality of anti-tumor T cells. We treated one patient with advanced (stage IV) melanoma, using the combination of laser immunotherapy (LIT), a novel immunological approach for metastatic cancers that has been shown to stimulate adaptive immunity, and ipilimumab. The patient was treated with LIT, followed with one course of ipilimumab 3 months after the beginning of LIT. After LIT treatment, all treated cutaneous melanoma in head and neck cleared completely. After the application of ipilimumab, all the tumor nodules in the lungs decreased. The patient had remained tumor free for one year. While anecdotal, the responses seen in this patient support the hypothesis that laser immunotherapy increases the number and quality of anti-tumor T cells so that ipilimumab and other checkpoint inhibitors are more effective in enhancing the therapeutic effects.

Stage III malignant melanoma is a heterogeneous disease where those cases deemed marginally resectable or irresecatble are frequently incurable by surgery alone. Targeted therapy takes advantage of the high incidence of BRAF mutations in melanomas, most notably the V600E mutation. These agents have rarely been used in a neoadjuvant setting prior to surgery. Thirteen consecutive patients with confirmed BRAF V600E regionally advanced melanoma deemed marginally resectable or irrresectable, were treated with BRAF inhibiting agents, prior to undergoing surgery. The primary outcome measures were a successful resection and pathological response. Disease-free survival was a secondary outcome measure. Overall, 12/13 patients showed a marked clinical responsiveness to medical treatment, enabling a macroscopically successful resection in all cases. Four patients had a complete pathological response with no viable tumor evident in the resected specimens and eight patients showed evidence of minimally residual tumor with extensive tumoral necrosis and fibrosis. One patient progressed and died before surgery. At a median follow up of 20 months, 10 patients remain free of disease. Perioperative treatment with BRAF inhibiting agents in BRAFV600E mutated Stage III melanoma patients facilitates surgical resection and affords satisfactory disease free survival. © 2017 Wiley Periodicals, Inc.

Conditional survival (CS) has emerged as a clinically relevant measure of prognosis for cancer survivors. The objective of this analysis was to provide melanoma-specific CS estimates to help clinicians promote more informed patient decision making. Patients with melanoma and at least 5 years of follow-up were identified from the Surveillance Epidemiology and End Results registry (1988-2000). By using the methods of Kaplan and Meier, stage-specific, 5-year CS estimates were independently calculated for survivors for each year after diagnosis. Stage-specific multivariate Cox regression models including baseline survivor functions were used to calculate adjusted melanoma-specific CS for different subgroups of patients further stratified by age, gender, race, marital status, anatomic tumor location, and tumor histology. Five-year CS estimates for patients with stage I disease remained constant at 97% annually, while for patients with stages II, III, and IV disease, 5-year CS estimates from time 0 (diagnosis) to 5 years improved from 72% to 86%, 51% to 87%, and 19% to 84%, respectively. Multivariate CS analysis revealed that differences in stages II through IV CS based on age, gender, and race decreased over time. Five-year melanoma-specific CS estimates improve dramatically over time for survivors with advanced stages of disease. These prognostic data are critical to patients for both treatment and nontreatment related life decisions. (c) 2010 American Cancer Society.

Cancer radiotherapy (RT) may induce what is referred to as the "abscopal effect," a regression of non-irradiated metastatic lesions distant from the primary tumor site directly subject to irradiation. This clinical response is rare, but has been surmised to be an immune-mediated phenomenon, suggesting that immunotherapy and RT could potentially synergize. Here, we report the outcome of patients with advanced melanoma treated with the immune checkpoint blockade monoclonal antibody antagonist, ipilimumab followed by RT. Patients were selected for enrollment at the National Cancer Institute "Fondazione G.Pascale" through the expanded access program in Italy. Those who experienced disease progression after ipilimumab thus received subsequent RT and were selected for analysis. Among 21 patients, 13 patients (62%) received RT to treat metastases in the brain and 8 received RT directed at extracranial sites. An abscopal response was observed in 11 patients (52%), 9 of whom had partial responses (43%) and 2 had stable disease (10%). The median time from RT to an abscopal response was 1 month (range 1-4). Median overall survival (OS) for all 21 patients was 13 months (range 6-26). Median OS for patients with abscopal responses was extended to 22.4 months (range 2.5-50.3) vs. 8.3 months (range 7.6-9.0) without. A local response to RT was detected in 13 patients (62%) and, of these, 11 patients (85%) had an abscopal response and abscopal effects were only observed among patients exhibiting a local response. These results suggest RT after ipilimumab may lead to abscopal responses in some patients with advanced melanoma correlating with prolonged OS. Our data also suggest that local responses to RT may be predictive of abscopal responses. Further research in larger randomized trials is needed to validate these results.

Context Serum creatinine has been reported to increase in patients receiving Vemurafenib, yet neither the prevalence nor the mechanism of this adverse event are known. Objective We aimed to evaluate the frequency and the mechanisms of increases in plasma creatinine level in patients receiving Vemurafenib for advanced melanoma. Methods We performed a retrospective monocentric study including consecutive patients treated with Vemurafenib for an advanced melanoma. We collected clinical and biological data concerning renal function before introduction of Vemurafenib and in the course of monthly follow-up visits from March 2013 to December 2014. Cystatin C-derived glomerular filtration rate was evaluated before and after Vemurafenib initiation, as increase in serum cystatin C is specific to a decrease in the glomerular filtration rate. We also performed thorough renal explorations in 3 patients, with measurement of tubular secretion of creatinine before and after Vemurafenib initiation and a renal biopsy in 2 patients. Results 70 patients were included: 97% of them displayed an immediate, and thereafter stable, increase in creatinine (+22.8%) after Vemurafenib initiation. In 44/52 patients in whom Vemurafenib was discontinued, creatinine levels returned to baseline. Serum cystatin C increased, although proportionally less than serum creatinine, showing that creatinine increase under vemurafenib was indeed partly due to a renal function impairment. In addition, renal explorations demonstrated that Vemurafenib induced an inhibition of creatinine tubular secretion. Conclusion Thus, Vemurafenib induces a dual mechanism of increase in plasma creatinine with both an inhibition of creatinine tubular secretion and slight renal function impairment. However, this side effect is mostly reversible when Vemurafenib is discontinued, and should not lead physicians to discontinue the treatment if it is effective. PMID:26930506

Laser immunotherapy (LIT) was developed for the treatment of metastatic tumors. It combines local selective photothermal interaction and active immunological stimulation to induce a long-term, systemic anti-tumor immunity. During the past sixteen years, LIT has been advanced from bench-top to bedside, with promising outcomes. In our pre-clinical and preliminary clinical studies, LIT has demonstrated the capability in inducing immunological responses, which not only can eradicate the treated primary tumors, but also can eliminate untreated metastases at distant sites. Specifically, LIT has been used to treat advanced melanoma and breast cancer patients during the past five years. LIT was shown to be effective in controlling both primary tumors and distant metastases in late-stage patients, who have failed conventional therapies such as surgery, chemotherapy, radiation, and other more advanced approaches. The methodology and the development of LIT are presented in this paper. The patients' responses to LIT are also reported in this paper. The preliminary results obtained in these studies indicated that LIT could be an effective modality for the treatment of patients with late-stage, metastatic cancers, who are facing severely limited options.

In phase I/II trials, the cytotoxic T lymphocyte-associated antigen-4-blocking monoclonal antibody tremelimumab induced durable responses in a subset of patients with advanced melanoma. This phase III study evaluated overall survival (OS) and other safety and efficacy end points in patients with advanced melanoma treated with tremelimumab or standard-of-care chemotherapy. Patients with treatment-naive, unresectable stage IIIc or IV melanoma were randomly assigned at a ratio of one to one to tremelimumab (15 mg/kg once every 90 days) or physician's choice of standard-of-care chemotherapy (temozolomide or dacarbazine). In all, 655 patients were enrolled and randomly assigned. The test statistic crossed the prespecified futility boundary at second interim analysis after 340 deaths, but survival follow-up continued. At final analysis with 534 events, median OS by intent to treat was 12.6 months (95% CI, 10.8 to 14.3) for tremelimumab and 10.7 months (95% CI, 9.36 to 11.96) for chemotherapy (hazard ratio, 0.88; P = .127). Objective response rates were similar in the two arms: 10.7% in the tremelimumab arm and 9.8% in the chemotherapy arm. However, response duration (measured from date of random assignment) was significantly longer after tremelimumab (35.8 v 13.7 months; P = .0011). Diarrhea, pruritus, and rash were the most common treatment-related adverse events in the tremelimumab arm; 7.4% had endocrine toxicities. Seven deaths in the tremelimumab arm and one in the chemotherapy arm were considered treatment related by either investigators or sponsor. This study failed to demonstrate a statistically significant survival advantage of treatment with tremelimumab over standard-of-care chemotherapy in first-line treatment of patients with metastatic melanoma.

The programmed death-1 inhibitor pembrolizumab has demonstrated efficacy and safety in clinical trials for treating advanced (unresectable/metastatic) melanoma. We investigated the real-world utilization of pembrolizumab and associated patient outcomes for advanced melanoma in US community oncology practices. This retrospective, observational study used deidentified data from electronic health records for adult patients with advanced melanoma who received pembrolizumab at The US Oncology Network sites from September 2014 through December 2015, with follow-up through September 2016. Patients enrolled in clinical trials were excluded. Overall survival (OS) and physician-stated progression-free survival (PFS) were analyzed from pembrolizumab initiation using Kaplan-Meier, and associations between pembrolizumab therapy and OS/PFS, using multivariable Cox regression. Of 168 patients studied, 110 (65%) were male; the median age was 66 years (range, 26–over 90). Pembrolizumab was prescribed as first-line, second-line, and third-line/later for 39 (23%), 87 (52%), and 42 (25%) patients, respectively. In total, 41 patients (24%) had brain metastases. At pembrolizumab initiation, 21/129 (16%) had Eastern Cooperative Oncology Group performance status (ECOG PS) >1; 51/116 (44%) had elevated lactate dehydrogenase. Median follow-up was 10.5 months (range, 0–25.1); median OS was 19.4 months (95% confidence interval, 14.0–not reached); median PFS was 4.2 months (95% confidence interval, 2.9–5.3). Brain metastases, ECOG PS>1, elevated lactate dehydrogenase, and third-line/later (vs. first-line) pembrolizumab were significant predictors (P<0.01) of decreased survival. Treatment-related toxicity was a discontinuation reason for 25% (29/117) of patients, and for 10 of these 29 patients (6% of the full-study cohort) treatment-related toxicity was the only reported reason. The real-world effectiveness and safety of pembrolizumab for advanced melanoma are consistent with clinical

Before 2011, patients with advanced or metastatic melanoma had a particularly poor long-term prognosis. Since traditional treatments failed to confer a survival benefit, patients were preferentially entered into clinical trials of investigational agents. A greater understanding of the epidemiology and biology of disease has underpinned the development of newer therapies, including six agents that have been approved in the EU, US and/or Japan: a cytotoxic T-lymphocyte antigen-4 inhibitor (ipilimumab), two programmed cell death-1 receptor inhibitors (nivolumab and pembrolizumab), two BRAF inhibitors (vemurafenib and dabrafenib) and a MEK inhibitor (trametinib). The availability of these treatments has greatly improved the outlook for patients with advanced melanoma; however, a major consideration for physicians is now to determine how best to integrate these agents into clinical practice. Therapeutic decisions are complicated by the need to consider patient and disease characteristics, and individual treatment goals, alongside the different efficacy and safety profiles of agents with varying mechanisms of action. Long-term survival, an outcome largely out of reach with traditional systemic therapies, is now a realistic goal, creating the additional need to re-establish how clinical benefit is evaluated. In this review we summarise the current treatment landscape in advanced melanoma and discuss the promise of agents still in development. We also speculate on the future of melanoma treatment and discuss how combination and sequencing approaches may be used to optimise patient care in the future. Copyright © 2015 Elsevier Ltd.

There is limited evidence on the costs associated with ipilimumab. We investigated healthcare costs of all Dutch patients with advanced cutaneous melanoma who were treated with ipilimumab. Data were retrieved from the nation-wide Dutch Melanoma Treatment Registry. Costs were determined by applying unit costs to individual patient resource use. A total of 807 patients who were diagnosed between July 2012 and July 2015 received ipilimumab in Dutch practice. The mean (median) episode duration was 6.27 (4.61) months (computed from the start of ipilimumab until the start of a next treatment, death, or the last date of follow-up). The average total healthcare costs amounted to &OV0556;81 484, but varied widely (range: &OV0556;18 131-&OV0556;160 002). Ipilimumab was by far the most important cost driver (&OV0556;73 739). Other costs were related to hospital admissions (&OV0556;3323), hospital visits (&OV0556;1791), diagnostics and imaging (&OV0556;1505), radiotherapy (&OV0556;828), and surgery (&OV0556;297). Monthly costs for resource use other than ipilimumab were &OV0556;1997 (SD: &OV0556;2629). Treatment-naive patients (n=344) had higher total costs compared with previously-treated patients (n=463; &OV0556;85 081 vs. &OV0556;78 811). Although patients with colitis (n=106) had higher costs for resource use other than ipilimumab (&OV0556;11 426) compared with patients with other types of immune-related adverse events (n=90; &OV0556;9850) and patients with no immune-related adverse event (n=611; &OV0556;6796), they had lower total costs (&OV0556;76 075 vs. &OV0556;87 882 and &OV0556;81 480, respectively). In conclusion, this nation-wide study provides valuable insights into the healthcare costs of advanced cutaneous melanoma patients who were treated with ipilimumab in clinical practice. Most of the costs were attributable to ipilimumab, but the costs and its distribution varied considerably across subgroups.

Metastatic melanoma responds poorly to systemic treatment. We report the results of a prospective single institution study evaluating O(6)-methylguanine-DNA methyltransferase (MGMT) status as a potential predictive and/or prognostic marker among patients treated with dacarbazine (DTIC) 800-1000 mg/m(2) monotherapy administered as a 3-weekly schedule for advanced malignant melanomas. The study was approved by the Regional Ethical Committee. Surgical biopsies from metastatic or loco-regional deposits obtained prior to DTIC treatment were snap-frozen immediately upon removal and stored in liquid nitrogen up to processing. Median time from enrolment to end of follow-up was 67 months. MGMT expression levels evaluated by qRT-PCR correlated significantly to DTIC benefit (CR/PR/SD; p=0.005), time to progression (TTP) (p=0.005) and overall survival (OS) (p=0.003). MGMT expression also correlated to Breslow thickness in the primary tumour (p=0.014). While MGMT promoter hypermethylation correlated to MGMT expression, MGMT promoter hypermethylation did not correlate to treatment benefit, TTP or OS, suggesting that other factors may be critical in determining MGMT expression levels in melanomas. In a Cox proportional regression analysis, serum lactate dehydrogenase (LDH, p<0.001), MGMT expression (p=0.022) and p16(INK4a) expression (p=0.037) independently predicted OS, while TTP correlated to DTIC benefit after 6 weeks only (p=0.001). Our data reveal MGMT expression levels to be associated with disease stabilisation and prognosis in patients receiving DTIC monotherapy for advanced melanoma. The role of MGMT expression as a predictor to DTIC sensitivity versus a general prognostic factor in advanced melanomas warrants further evaluation. Copyright 2010 Elsevier Ltd. All rights reserved.

The prognosis of metastatic melanoma has changed markedly in recent years because of the advent of newer targeted therapies such as BRAF inhibitors. However, the response to BRAF inhibitor therapy is frequently nondurable in patients with advanced melanoma. Novel approaches are thus needed to overcome resistance to these agents and to improve the management of advanced melanoma patients after disease progression. Here, we present the case of a 44-year-old man diagnosed with advanced melanoma in July 2010, harboring a BRAF mutation. Melanoma progressed during first-line chemotherapy with dacarbazine, but showed significant benefit after the initiation of vemurafenib on August 2011. Six months later, the patient experienced disease progression in left-obturator lymphadenopathy; still, anti-BRAF treatment was continued together with stereotactic radiotherapy, and was interrupted only shortly for intestinal occlusion secondary to melanoma metastasis of the bowel. When his conditions were stable, after 1 month of vemurafenib treatment discontinuation, anti-BRAF therapy was reinitiated, with a positive outcome. Vemurafenib treatment was definitively discontinued for disease progression in the brain, peritoneum, lymph node, intestine, and skin in March 2013, after about 20 months from initiation, and the patient died a few weeks later. The clinical case presented here shows that treatment beyond progression with vemurafenib can yield a survival benefit in melanoma patients whose disease progresses in a few sites, which can be treated with locoregional therapies. This clinical strategy needs further validation in prospective clinical trials.

Blocking autophagy with hydroxychloroquine (HCQ) augments cell death associated with alkylating chemotherapy in preclinical models. This phase I study evaluated the maximum tolerated dose (MTD), safety, preliminary activity, pharmacokinetics, and pharmacodynamics of HCQ in combination with dose-intense temozolomide (TMZ) in patients with advanced solid malignancies. Forty patients (73% metastatic melanoma) were treated with oral HCQ 200 to 1200 mg daily with dose-intense oral TMZ 150 mg/m (2) daily for 7/14 d. This combination was well tolerated with no recurrent dose-limiting toxicities observed. An MTD was not reached for HCQ and the recommended phase II dose was HCQ 600 mg twice daily combined with dose-intense TMZ. Common toxicities included grade 2 fatigue (55%), anorexia (28%), nausea (48%), constipation (20%), and diarrhea (20%). Partial responses and stable disease were observed in 3/22 (14%) and 6/22 (27%) patients with metastatic melanoma. In the final dose cohort 2/6 patients with refractory BRAF wild-type melanoma had a near complete response, and prolonged stable disease, respectively. A significant accumulation in autophagic vacuoles (AV) in peripheral blood mononuclear cells was observed in response to combined therapy. Population pharmacokinetics (PK) modeling, individual PK simulations, and PK-pharmacodynamics (PD) analysis identified a threshold HCQ peak concentration that predicts therapy-associated AV accumulation. This study indicates that the combination of high-dose HCQ and dose-intense TMZ is safe and tolerable, and is associated with autophagy modulation in patients. Prolonged stable disease and responses suggest antitumor activity in melanoma patients, warranting further studies of this combination, or combinations of more potent autophagy inhibitors and chemotherapy in melanoma.

Vitiligo is occasionally seen in melanoma patients. Although several studies indicate a correlation between vitiligo occurrence and clinical response in melanoma patients receiving immunotherapy, most studies have included heterogeneous patient and treatment settings. The aim of this study is to investigate the correlation between the occurrence of vitiligo and clinical benefit of nivolumab treatment in advanced melanoma patients. We retrospectively reviewed unresectable stage III or IV melanoma patients treated with nivolumab. Of 35 melanoma patients treated with nivolumab, 25.7% (9/35) developed vitiligo during treatment. The time from the start of nivolumab treatment to occurrence of vitiligo ranged 2-9 months (mean, 5.2). Of nine patients who developed vitiligo, two (22.2%) had a complete response to nivolumab and two (22.2%) had a partial response. The objective response rate was significantly higher in patients with vitiligo than in patients without vitiligo (4/9 [44.4%] vs 2/26 [7.7%]; P = 0.027). The mean time to vitiligo occurrence in patients achieving an objective response was significantly less than that in patients who showed no response (3.1 vs 6.8 months, P = 0.004). Vitiligo occurrence was significantly associated with prolonged progression-free and overall survival (hazard ratio, 0.24 and 0.16; 95% confidence interval, 0.11-0.55 and 0.03-0.79; P = 0.005, and 0.047, respectively). At the 20-week landmark analysis, however, vitiligo was not associated with a statistically significant overall survival benefit (P = 0.28). The occurrence of vitiligo during nivolumab treatment may be correlated with favorable clinical outcome. © 2016 Japanese Dermatological Association.

The importance of immune responses in the control of melanoma growth is well known. However, the implication of these antitumor immune responses in the efficacy of dacarbazine, a cytotoxic drug classically used in the treatment of melanoma, remains poorly understood in humans. In this prospective observational study, we performed an immunomonitoring of eleven metastatic or locally advanced patients treated with dacarbazine as a first line of treatment. We assessed by flow cytometry lymphoid populations and their activation state; we also isolated NK cells to perform in vitro cytotoxicity tests. We found that chemotherapy induces lymphopenia and that a significantly higher numbers of naïve CD4+ T cells and lower proportion of Treg before chemotherapy are associated with disease control after dacarbazine treatment. Interestingly, NK cell cytotoxicity against dacarbazine-pretreated melanoma cells is only observed in NK cells from patients who achieved disease control. Together, our data pinpoint that some immune factors could help to predict the response of melanoma patients to dacarbazine. Future larger scale studies are warranted to test their validity as prediction markers.

As calculated by the meta-analysis of Korn et al., the prognosis of metastatic melanoma in the pretarget and immunological therapy era was poor, with a median survival of 6.2 and a 1-year life expectancy of 25.5%. Nowadays, significant advances in melanoma treatment have been gained, and immunotherapy is one of the promising approaches to get to durable responses and survival improvement. The aim of the present review is to highlight the recent innovations in melanoma immunotherapy and to propose a critical perspective of the future directions of this enthralling oncology subspecialty.

Vemurafenib: a new treatment for BRAF-V600 mutated advanced melanoma

PubMed Central

Fisher, Rosalie; Larkin, James

2012-01-01

The BRAF inhibitor, vemurafenib, has demonstrated improved progression-free and overall survival compared with chemotherapy in a randomized trial, and represents a new standard of care in patients with advanced melanoma harboring a BRAF-V600 mutation. A BRAF-V600 mutation is identified in approximately half of patients with cutaneous melanoma, and is unequivocally a biomarker predictive of profound clinical benefit for these patients. However, acquired vemurafenib resistance is a major clinical challenge and therapy is not yet curative. A substantial body of translational research has been performed alongside clinical trials of vemurafenib, providing key insights into the molecular basis of response and resistance. This review summarizes the development of vemurafenib for the treatment of BRAF-V600 mutant melanoma and discusses how knowledge of critical signaling pathways will be applied for its optimal clinical use in future.

Current treatment of advanced melanoma is rapidly changing with the introduction of new and effective therapies including systemic as well as locoregional therapies. An example of one such locoregional therapy is intralesional injection with talimogene laherparepvec (T-VEC). Areas covered: T-VEC has been shown in a number of studies to be an effective treatment for patients with stage IIIB, IIIC and IVM1a melanoma. In this article the effectiveness, pharmacokinetics and safety profile of T-VEC is reviewed. Additionally, new research looking at combinations of T-VEC and systemic immunotherapies is reviewed. Expert opinion: Overall, T-VEC is an easily administered, safe, well tolerated and effective oncolytic viral therapy for the treatment of stage IIIB, IIIC, IVM1a unresectable and injectable metastatic melanoma. Recently published studies are showing promising results when T-VEC is combined with systemic therapy and this may be the way of the not too distant future in how we treat metastatic melanoma. Continued work regarding the use of T-VEC with other systemic agents will provide new and more effective treatment strategies for advanced melanoma.

Purpose There is evidence from nonrandomized studies that a proportion of ipilimumab-treated patients with advanced melanoma experience long-term survival. To demonstrate a long-term survival benefit with ipilimumab, we evaluated the 5-year survival rates of patients treated in a randomized, controlled phase III trial. Patients and Methods A milestone survival analysis was conducted to capture the 5-year survival rate of treatment-naive patients with advanced melanoma who received ipilimumab in a phase III trial. Patients were randomly assigned 1:1 to receive ipilimumab at 10 mg/kg plus dacarbazine (n = 250) or placebo plus dacarbazine (n = 252) at weeks 1, 4, 7, and 10 followed by dacarbazine alone every 3 weeks through week 22. Eligible patients could receive maintenance ipilimumab or placebo every 12 weeks beginning at week 24. A safety analysis was conducted on patients who survived at least 5 years and continued to receive ipilimumab as maintenance therapy. Results The 5-year survival rate was 18.2% (95% CI, 13.6% to 23.4%) for patients treated with ipilimumab plus dacarbazine versus 8.8% (95% CI, 5.7% to 12.8%) for patients treated with placebo plus dacarbazine (P = .002). A plateau in the survival curve began at approximately 3 years. In patients who survived at least 5 years and continued to receive ipilimumab, grade 3 or 4 immune-related adverse events were observed exclusively in the skin. Conclusion The additional survival benefit of ipilimumab plus dacarbazine is maintained with twice as many patients alive at 5 years compared with those who initially received placebo plus dacarbazine. These results demonstrate a durable survival benefit with ipilimumab in advanced melanoma. PMID:25713437

Given its propensity to metastasize, and lack of effective therapies for most patients with advanced disease, early detection of melanoma is a clinical imperative. Although there are no non-invasive techniques for definitive diagnosis of melanoma, and the “gold standard” remains biopsy with histologic examination, a variety of modalities may facilitate early melanoma diagnosis and the detection of new and changing nevi. This article reviews general clinical principles of early melanoma detection, and various modalities that are currently available or on the horizon, providing the clinician with an up-to-date understanding of management strategies for their patients with numerous or atypical nevi. Learning objectives At the conclusion of this learning activity, participants should: 1) understand the clinical importance of early melanoma detection; 2) appreciate the challenges of early melanoma diagnosis and which patients are at highest risk; 3) know general principles of early melanoma detection; 4) be familiar with current and emerging modalities that may facilitate early melanoma diagnosis and the detection of new and changing nevi; 5) know the advantages and limitations of each modality; and 6) be able to practice a combined approach to the patient with numerous or clinically atypical nevi.

Purpose The combination of the oral alkylating agent temozolomide and the oral multi-kinase inhibitor sorafenib was evaluated in advanced melanoma patients. Patients and Methods Patients with metastatic melanoma (N=167) were treated on four arms. All patients received sorafenib at 400 mg orally twice daily without interruption. Patients without brain metastases or prior temozolomide were randomized between Arm A: extended dosing of temozolomide (EDT; 75 mg/m2 temozolomide daily for 6/8 weeks) and Arm B: standard dosing (SDT; 150 mg/m2 temozolomide daily for 5/28 days). Patients previously treated with temozolomide were enrolled on Arm C: EDT. Patients with brain metastases and no prior temozolomide were assigned to Arm D: SDT. The primary endpoint was 6-month progression-free survival (PFS) rate. Secondary endpoints included response rate, toxicity rates, and the rates of BRAF or NRAS mutations. Results The 6-month PFS rate for arms A, B, C, and D were 50%, 40%, 11%, and 23%. The median PFS for patients on arm A, B, C, and D was 5.9, 4.2, 2.2, and 3.5 months, respectively. No significant differences were observed between Arms A and B in 6-month PFS rate, median PFS, or response rates. Treatment was well tolerated in all arms. No significant differences in toxicity were observed between arms A and B except for more grade 3–4 lymphopenia in arm A. Conclusion Temozolomide plus sorafenib was well tolerated and demonstrated activity in melanoma patients without prior history of temozolomide. The activity of this combination regimen warrants further investigation. PMID:19996224

Melanoma is one of the most aggressive tumors with a very low survival rate once metastasized. The incidence of newly detected cases increases every year suggesting the necessity of development and application of innovative treatment strategies. Human melanoma develops from melanocytes localized in the epidermis of the skin to malignant tumors because of deregulated effectors influencing several molecular pathways. Despite many advances in describing the molecular changes accompanying melanoma formation, many critical and clinically relevant molecular features of the transformed pigment cells and the underlying mechanisms are largely unknown. To contribute to a better understanding of the molecular processes of melanoma formation, we use a transgenic medaka melanoma model that is well suited for the investigation of melanoma tumor development because fish and human melanocytes are both localized in the epidermis. The purpose of our study was to gain insights into melanoma development from the first steps of tumor formation up to melanoma progression and to identify gene expression patterns that will be useful for monitoring treatment effects in drug screening approaches. Comparing transcriptomes from juvenile fish at the tumor initiating stage with nevi and advanced melanoma of adults, we identified stage specific expression signatures and pathways that are characteristic for the development of medaka melanoma, and are also found in human malignancies.

Circulating tumor DNA (ctDNA) has been reported as a prognostic marker in melanoma. In BRAF V600-mutant melanoma, a plasma under-exposure to vemurafenib could favor emerging resistance but no biological data are available to support this hypothesis. We aimed to investigate the relationship between vemurafenib plasma concentrations and the ctDNA plasma concentration during follow-up of BRAF-mutated melanoma patients. Eleven patients treated with single-agent vemurafenib for advanced BRAF V600-mutant melanoma were analyzed in an exploratory monocentric study. The vemurafenib plasma concentration was measured by liquid chromatography. ctDNA was extracted from plasma samples and the ctDNA concentration was evaluated using picoliter droplet-based digital PCR with Taqman ® detection probes targeting the BRAF p.V600E/K mutation and wild-type BRAF sequences. At baseline, plasma ctDNA was detectable in 72% (n = 8/11) of patients and the ctDNA concentration decreased in 88% of these patients (n = 7/8) from day (D) 0 to D15 after vemurafenib initiation. During follow-up, an increased ctDNA concentration was detected in nine patients: in five patients, the first increase in ctDNA concentrations followed a decrease in vemurafenib concentrations. More interestingly, an inverse correlation between vemurafenib concentration and ctDNA concentrations was demonstrated (p = 0.026). The ctDNA concentration at baseline was associated with overall survival (hazard ratio = 2.61, 95% CI 1.04-6.56; p = 0.04). This study demonstrates the relevance of vemurafenib plasma monitoring during the follow-up of metastatic melanoma patients. Plasma drug monitoring and ctDNA concentrations could be combined to monitor tumor evolution in melanoma patients treated with anti-BRAF therapies.

The incidence of cutaneous melanoma has rapidly increased in the white population over the last decades. It has been estimated that the incidence doubles world-wide every 10 years. Different risk factors have been identified, including immunosuppression. The aim of our study-was to determine the relative risk of developing melanoma in the organ transplant population and the clinical and histological features of their melanomas. This retrospective study was conducted with the collaboration of 9 University Hospital Centers: Besançon, Brest, Caen, Dijon, Lille, Lyon, Nantes, Paris (Pitié-Salpétrière) and Rennes. A questionnaire was sent to the different departments of dermatology of these hospitals to obtain information on patients who had presented a melanoma after a transplantation between 1971 and 1997. During this period, there were 12,477 organ transplant recipients in the transplantation units of these 9 hospitals. Average follow-up for these patients was about 5 years and the average duration of immunosuppressive therapy was about 4.5 years. Among 12,477 organ transplant recipients, we found 17 cases of melanoma but no data could be obtain on one case: 14 occurred in renal transplant recipients and 3 in cardiac transplant recipients. Clinical and histological data were only available in 16 patients. The average time between transplantation and diagnosis of melanoma was 63 months, but it was 5 times shorter for 2 patients who had a past history of melanoma before transplantation. Two patients had a mucosal melanoma; for the cutaneous melanomas, 2 appeared on Dubreuilh melanosis, 2 were in situ melanomas, 7 were superficial spreading melanomas and 3 were nodular melanomas. The histological review of 11 cutaneous melanomas revealed a precursor nevus in 6 cases and a weak or no stroma reaction in 7/7 cases. Complete excision of the melanoma was performed in all patients except one with anorectal melanoma. Four patients died of visceral metastasis within a mean

Objective The study objective was to measure the rates of inclusion of populations at risk of advanced melanoma in a pilot targeted screening project involving general practitioners. Design This cross-sectional database study compared the inclusion rates of patients who signed inclusion in a targeted screening project with those of patients who did not, during a period in which both groups of patients consulted investigators. Setting Data were extracted from the national healthcare insurance records in western France from 11 April to 30 October 2011. Patients Patients, older than 18, considered for the data extraction had consulted one of the 78 participating GPs during the study period, and were affiliated with the national healthcare insurance. Main outcome measures Inclusion in the screening was the main outcome measure. Patients at risk of advanced melanoma were characterized by male gender, age over 50, low income, rural residence, farmer, and presence of chronic disease. Results A total of 57,279 patients consulted GPs during the inclusion period and 2711 (4.73%) were included in the targeted screening. Populations at risk of advanced melanoma were less included: men (OR = 0.67; 95%CI [0.61–0.73]; p < 0.001), older than 50 (OR = 0.67; 95%CI [0.60–0.74]; p < 0.001), low income (OR = 0.65; 95%CI [0.55–0.77]; p < 0.001), farmer (OR = 0.23; 95%CI [0.17–0.30]; p < 0.001) and presence of a chronic disease (OR = 0.87; 95%CI [0.77–0.98]; p < 0.028). Conclusion This study demonstrated inequalities in the inclusion of patients in a melanoma screening. Patients at risk of advanced cancer were screened less often. Further studies should focus on GPs ability to identify and screen these patients. Key Points Advanced melanoma is more frequently diagnosed in men, older patients and socioeconomically disadvantaged populations, which leads to survival inequalities.• Despite the involvement of general practitioners, the

Purpose Patients who are diagnosed with stage IV metastatic melanoma have an estimated 5-year relative survival rate of only 17%. Randomized controlled trials of recent US Food and Drug Administration–approved immune checkpoint inhibitors—pembrolizumab (PEM), nivolumab (NIVO), and ipilumumab (IPI)—demonstrate improved patient outcomes, but the optimal treatment sequence in patients with BRAF wild-type metastatic melanoma remains unclear. To inform policy makers about the value of these treatments, we developed a Markov model to compare the cost-effectiveness of different strategies for sequencing novel agents for the treatment of advanced melanoma. Materials and Methods We developed Markov models by using a US-payer perspective and lifetime horizon to estimate costs (2016 US$) and quality-adjusted life years (QALYs) for treatment sequences with first-line NIVO, IPI, NIVO + IPI, PEM every 2 weeks, and PEM every 3 weeks. Health states were defined for initial treatment, first and second progression, and death. Rates for drug discontinuation, frequency of adverse events, disease progression, and death obtained from randomized phase III trials were used to determine the likelihood of transition between states. Deterministic and probabilistic sensitivity analyses were conducted to evaluate model uncertainty. Results PEM every 3 weeks followed by second-line IPI was both more effective and less costly than dacarbazine followed by IPI then NIVO, or IPI followed by NIVO. Compared with the first-line dacarbazine treatment strategy, NIVO followed by IPI produced an incremental cost effectiveness ratio of $90,871/QALY, and first-line NIVO + IPI followed by carboplatin plus paclitaxel chemotherapy produced an incremental cost effectiveness ratio of $198,867/QALY. Conclusion For patients with treatment-naive BRAF wild-type advanced melanoma, first-line PEM every 3 weeks followed by second-line IPI or first-line NIVO followed by second-line IPI are the most cost

Patients with potentially resectable advanced stage III and IV melanoma are a selected subgroup that gain maximal advantage if treated in a melanoma center. Surgery combined with chemo/chemobiotherapy may yield durable remission and long-term palliation. Thirty-seven non-randomly selected patients underwent systemic therapy with the aim of consolidating treatment by surgery. Data were collected prospectively, and analyzed retrospectively. The median follow-up from diagnosis was 50 (3-307) months and 15 (1-156) months when calculated from the last intervention. Twenty-two males and 15 females, with a median age at diagnosis of 44 (20-71) years, with 13 trunk, 13 extremity, 3 head and neck and 8 unknown primary melanomas were included. There were 17 stage III and 20 stage IV patients with a median Breslow thickness of 3.7 (0.45-26) mm. Chemo/chemobiotherapy achieved 7 clinical complete responses (cCRs), 28 partial responses (PRs) and 2 instances of stable disease. Six of the 7 cCRs were operated on, securing pathological complete response in 5 and PR in one. Four of these five and the PR patient still have no evidence of disease (NED). Twenty-one of 30 PR patients were rendered NED by surgery; 14 of these 21 patients succumbed to melanoma, and one is alive with stable disease. Overall, 11 of 37 patients have not succumbed to melanoma, with a median of 72 (14-156) months survival following the last intervention. Of the eight patients with unknown primary melanomas, five have not succumbed to melanoma, with a median of 89 (30-156) months survival following the last intervention. Patients with marginally resectable stage III and IV melanoma have a significant 30% chance, according to this series, for durable remission if treated by a multidisciplinary team in a melanoma center using induction chemobiotherapy and surgery. Results are more favorable for patients with an unknown primary lesion. In view of the currently approved new effective treatments for melanoma, this

Immunotherapy plays a key role in the treatment of metastatic melanoma. Patients with autoimmune conditions and/or on immunosuppressive therapy due to orthotropic transplants, however, are systematically excluded from clinical trials. Talimogene laherparepvec (T-VEC) is the first oncolytic virus to be approved by the FDA for cancer therapy. To our knowledge, this is the first report of T-VEC being administered in the setting of an organ transplant recipient. Here we present the case of a patient with recurrent locally advanced cutaneous melanoma receiving salvage T-VEC therapy in the setting of orthotropic heart transplantation. After 5 cycles of therapy, no evidence of graft rejection has been observed to date, and the patient achieved a complete remission, and is currently off therapy. This case advocates for further investigation on the safety and efficacy of immunotherapeutic approaches, such as T-VEC, in solid organ transplant recipients.

Therapeutic strategies for the treatment of metastatic melanoma show encouraging results in the clinic; however, not all patients respond equally and tumor resistance still poses a challenge. To identify novel therapeutic targets for melanoma, we screened a panel of structurally diverse organometallic inhibitors against human-derived normal and melanoma cells. We observed that a compound that targets PIM kinases (a family of Ser/Thr kinases) preferentially inhibited melanoma cell proliferation, invasion, and viability in adherent and three-dimensional (3D) melanoma models. Assessment of tumor tissue from melanoma patients showed that PIM kinases are expressed in pre- and post-treatment tumors, suggesting PIM kinases as promising targets in the clinic. Using knockdown studies, we showed that PIM1 contributes to melanoma cell proliferation and tumor growth in vivo; however, the presence of PIM2 and PIM3 could also influence the outcome. The inhibition of all PIM isoforms using SGI-1776 (a clinically-available PIM inhibitor) reduced melanoma proliferation and survival in preclinical models of melanoma. This was potentiated in the presence of the BRAF inhibitor PLX4720 and in the presence of PI3K inhibitors. Our findings suggest that PIM inhibitors provide promising additions to the targeted therapies available to melanoma patients. PMID:27448973

Liquid biopsy utility for the surveillance of cutaneous malignant melanoma patients.

Cutaneous melanoma is one of the highest incident-rate cancers with increasing prevalence in Western societies. Despite the advent of new approved therapeutics, the 5-year overall survival rate of stage IV melanoma patients remains below 15%. Current treatments for late stage disease have shown higher efficacy when treated at a lower disease burden. Thus, blood-based biomarkers capable of detecting melanoma prior to clinically evident distant metastasis, will improve the treatment and outcomes for melanoma patients. To that end, effective treatment of melanoma necessitates identification of patients at risk for developing distant metastases. Furthermore, employing blood biomarkers that monitor cancer progression over the course of treatment is a promising solution to post-treatment drug resistance often developed in melanoma patients. Non-invasive blood biomarker assays allow for regular dynamic monitoring of disease. "Liquid Biopsy" of blood, which exploits circulating tumor cells (CTCs), cell-free circulating tumor DNA (ctDNA) and cell-free circulating microRNA (cmiRNA), has been shown to detect prognostic factors for relapse in AJCC stage III and stage IV melanoma patients. Moreover, molecular characterization of CTC and analysis of various forms of ctDNA present promising potential in development of individualized therapy for melanoma patients. New approaches such as massive parallel sequencing (MPS) provide a comprehensive view of the disease progression, allowing for the selection of therapeutic options for individual patients. With advancements of improving molecular assays, liquid biopsy analysis as a powerful, routine clinical assay for melanoma patients, is highly promising prospective.

Selective BRAF inhibition (BRAFi) by vemurafenib or dabrafenib has become approved standard treatment in BRAF V600 mutated advanced stage melanoma. While the response rate is high, the response duration is limited with a progression-free survival (PFS) of 5-6months. Our observation of accelerated disease progression within some patients after stopping vemurafenib treatment has fostered the idea of treatment beyond progression (BRAFi TBP). In this retrospective study, we analysed 70 metastatic melanoma patients, treated at our institute, who experienced progression after prior objective response upon treatment with vemurafenib. Thirty-five patients that continued treatment beyond progression are compared with 35 patients who stopped BRAFi treatment at disease progression. Median overall survival beyond documented progression was found to be 5.2months versus 1.4months (95% confidence interval (CI): 3.8-7.4 versus 0.6-3.4; Log-Rank p=0.002) in favour of BRAFi TBP. In the multivariate survival analysis, stopping treatment at disease progression was significantly associated with shorter survival (hazard ratio: 1.92; 95% CI: 1.04-3.55; p=0.04). Our results suggest that continuing vemurafenib treatment beyond progression may be beneficial in advanced melanoma patients, who prior to progression responded to vemurafenib.

Vemurafenib improves survival in advanced BRAFV600(mut) melanoma patients, but tolerance is often poor and resistance frequently occurs, without predictive factor. Our aim was to investigate for the first time a relationship between plasma vemurafenib concentration (PVC) and efficacy or tolerance. Plasma samples from unresectable metastatic BRAFV600(mut) melanoma patients treated with vemurafenib monotherapy were prospectively collected at each tumour response evaluation (RECIST 1.1) or when adverse event occurred (CTCAE 4.0). PVC was measured with liquid chromatography-tandem mass spectrometry. Herein, we report on PVC at steady state (≥14 days after vemurafenib introduction or dose modification). Samples collected after first melanoma progression were excluded from the response analysis. All samples were analysed in the tolerance analysis. We kept the closest collected sample from the onset of each adverse effect or the one with the highest PVC in the absence of this adverse effect. Comparisons of means (Student's t-tests and Wilcoxon rank sum tests) and of frequencies (χ(2) tests) were carried out. A logistic regression analysis identified predictors of progression. We included 105 plasma samples in 23 patients (10M/13F). Initial vemurafenib dose was 960 mg b.i.d., reduced by 25% (8 patients) or 50% (2 patients) for intolerance in 10 patients (44%). PVC displayed high inter-individual variability (13.0-109.8 µg/ml, median 54.0). Mean PVC was lower at time of first progression (38.8 ± 19.7 µg/ml) than mean PVC found when tumour was stable or in partial or complete response (56.4 ± 21.0 µg/ml, P = 0.013, 21 patients). Logistic regression revealed that having a low PVC (P = 0.01) or brain metastasis (P = 0.01) were both significantly and independently associated with tumour progression. High PVC was not statistically significantly associated with the occurrence of adverse effects. PVC at steady state is highly variable and low PVC was associated with tumour

Adoptive therapy for cancer using tumor-infiltrating lymphocytes (TIL) has mainly been investigated in cancer patients with advanced stage disease. The limited clinical success has not been encouraging, although this might be explained by poor TIL specificity and/or high tumor burden. To re-evaluate the effectiveness of adoptive therapy, we analyzed the capacity of tumor-reactive TIL injection in preventing the further development of disease in stage III melanoma patients after complete tumor resection. A phase II/III randomized trial was performed on 88 melanoma patients, who received autologous TIL plus interleukin-2 (IL-2) or IL-2 only. The duration of relapse-free survival was analyzed, taking into account the immunological specificity of injected TIL and the number of metastatic lymph nodes removed before treatment. Kaplan-Meyer analysis revealed that the injection of tumor-reactive TIL was statistically correlated with prolonged relapse-free survival in patients with only one metastatic lymph node. Therefore, improved clinical outcome could be obtained after adoptive therapy by selecting appropriate groups of patients and monitoring the specificity of the injected TIL populations.

Report results of patient-reported health-related quality of life (HRQoL) and symptoms from phase III KEYNOTE-006 study of pembrolizumab versus ipilimumab in patients with ipilimumab-naive advanced melanoma. Patients received pembrolizumab 10 mg/kg every 2 (Q2W) or every 3 weeks (Q3W) for up to 2 years, or four cycles of ipilimumab 3 mg/kg Q3W. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) was administered at baseline and throughout the study. Patient-reported outcome (PRO) analyses were pre-specified exploratory endpoints; the primary PRO assessment was the score change from baseline to week 12 in EORTC QLQ-C30 global health status (GHS)/HRQoL score between the arms using constrained longitudinal data analysis. The PRO analysis population included 776 patients: pembrolizumab Q2W (n = 270); pembrolizumab Q3W (n = 266); ipilimumab (n = 240). Baseline GHS was similar across arms. QLQ-C30 compliance rates at week 12 were 87% (n = 214), 97% (n = 226), and 96% (n = 178), for the pembrolizumab Q2W, pembrolizumab Q3W, and ipilimumab arms, respectively. From baseline to week 12, GHS/HRQoL scores were better maintained with pembrolizumab than with ipilimumab (decrease of -1.9 and -2.5 for pembrolizumab versus -10.0 for ipilimumab; p < 0.001 for each pembrolizumab arm versus ipilimumab). Fewer patients treated with pembrolizumab experienced deterioration in GHS at week 12 (31% for pembrolizumab Q2W; 29% for Q3W and 44% for ipilimumab), with similar trends observed for individual functioning and symptoms scales. HRQoL was better maintained with pembrolizumab than with ipilimumab in patients with ipilimumab-naive advanced melanoma. CLINICALTRIALS. NCT01866319. Copyright © 2017 The Author(s).

There are no established therapies specific for NRAS-mutant melanoma despite the emergence of immunotherapy. We aimed to assess the efficacy and safety of the MEK inhibitor binimetinib versus that of dacarbazine in patients with advanced NRAS-mutant melanoma. NEMO is an ongoing, randomised, open-label phase 3 study done at 118 hospitals in 26 countries. Patients with advanced, unresectable, American Joint Committee on Cancer stage IIIC or stage IV NRAS-mutant melanoma who were previously untreated or had progressed on or after previous immunotherapy were randomised (2:1) to receive either binimetinib 45 mg orally twice daily or dacarbazine 1000 mg/m 2 intravenously every 3 weeks. Randomisation was stratified by stage, performance status, and previous immunotherapy. The primary endpoint was progression-free survival assessed by blinded central review in the intention-to-treat population. Safety analyses were done in the safety population, consisting of all patients who received at least one study drug dose and one post-baseline safety assessment. This study is registered with ClinicalTrials.gov, number NCT01763164 and with EudraCT, number 2012-003593-51. Between Aug 19, 2013, and April 28, 2015, 402 patients were enrolled and randomly assigned, 269 to binimetinib and 133 to dacarbazine. Median follow-up was 1·7 months (IQR 1·4-4·1). Median progression-free survival was 2·8 months (95% CI 2·8-3·6) in the binimetinib group and 1·5 months (1·5-1·7) in the dacarbazine group (hazard ratio 0·62 [95% CI 0·47-0·80]; one-sided p<0·001). Grade 3-4 adverse events seen in at least 5% of patients the safety population in either group were increased creatine phosphokinase (52 [19%] of 269 patients in the binimetinib group vs none of 114 in the dacarbazine group), hypertension (20 [7%] vs two [2%]), anaemia (five [2%] vs six [5%]), and neutropenia (two [1%] vs ten [9%]). Serious adverse events (all grades) occurred in 91 (34%) patients in the binimetinib group and 25

Background. Vemurafenib has been approved for the treatment of patients with advanced BRAFV600E-mutant melanoma. This report by the Vemurafenib Dermatology Working Group presents the characteristics of dermatologic adverse events (AEs) that occur in vemurafenib-treated patients, including cutaneous squamous cell carcinoma (cuSCC). Methods. Dermatologic AEs were assessed from three ongoing trials of BRAFV600E mutation-positive advanced melanoma. Histologic central review and genetic characterization were completed for a subset of cuSCC lesions. Results. A total of 520 patients received vemurafenib. The most commonly reported AEs were dermatologic AEs, occurring in 92%–95% of patients. Rash was the most common AE (64%–75% of patients), and the most common types were rash not otherwise specified, erythema, maculopapular rash, and folliculitis. Rash development did not appear to correlate with tumor response. Photosensitivity occurred in 35%–63% of patients, and palmar-plantar erythrodysesthesia (PPE) occurred in 8%–10% of patients. The severity of rash, photosensitivity, and PPE were mainly grade 1 or 2. In all, 19%–26% of patients developed cuSCC, mostly keratoacanthomas (KAs). The majority of patients with cuSCC continued therapy without dose reduction after resection. Genetic analysis of 29 cuSCC/KA samples demonstrated HRAS mutations in 41%. Conclusions. Dermatologic AEs associated with vemurafenib treatment in patients with melanoma were generally manageable with supportive care measures. Dose interruptions and/or reductions were required in <10% of patients. PMID:23457002

The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today's standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging. Sarcoidosis is a multisystemic granulomatous disease characterized by an aberrant immune response to unknown antigens, whereas sarcoid-like reactions (SLRs) refer to localized clinical features. We carried out a single-center observational study in patients with stage IIB-IV melanoma treated with BRAF/MEK inhibitors and immune checkpoint inhibitors. A description of the sarcoidosis-related manifestations was provided from patients' records. We observated eight cases of SLRs in a cohort of 200 patients. The clinical courses were characterized by a variety of symptoms, accompanied by cutaneous signs and extracutaneous manifestations such as bilateral, hilar lymphadenopathy. We identified a histologically granulomatous inflammation involving the skin, the lungs, and the lymph nodes. Two patients presented with cutaneous lesions only, and three patients had lung involvement only. Three patients achieved complete and partial response of the melanoma disease, and three patients had stable disease. Disease progression was documented in two patients. The reported immune-related adverse events were mild to severe and in most of the cases were continued without any treatment cessation. SLRs appear during treatment with both kinase and immune checkpoint inhibitors. Awareness of these can avoid misdiagnosis of disease progression and unnecessary treatment changes.

The utilization of healthcare services and costs among patients with cancer is often estimated by the phase of care: initial, interim, or terminal. Although their durations are often set arbitrarily, we sought to establish data-driven phases of care using joinpoint regression in an advanced melanoma population as a case example. A retrospective claims database study was conducted to assess the costs of advanced melanoma from distant metastasis diagnosis to death during January 2010-September 2014. Joinpoint regression analysis was applied to identify the best-fitting points, where statistically significant changes in the trend of average monthly costs occurred. To identify the initial phase, average monthly costs were modeled from metastasis diagnosis to death; and were modeled backward from death to metastasis diagnosis for the terminal phase. Points of monthly cost trend inflection denoted ending and starting points. The months between represented the interim phase. A total of 1,671 patients with advanced melanoma who died met the eligibility criteria. Initial phase was identified as the 5-month period starting with diagnosis of metastasis, after which there was a sharp, significant decline in monthly cost trend (monthly percent change [MPC] = -13.0%; 95% CI = -16.9% to -8.8%). Terminal phase was defined as the 5-month period before death (MPC = -14.0%; 95% CI = -17.6% to -10.2%). The claims-based algorithm may under-estimate patients due to misclassifications, and may over-estimate terminal phase costs because hospital and emergency visits were used as a death proxy. Also, recently approved therapies were not included, which may under-estimate advanced melanoma costs. In this advanced melanoma population, optimal duration of the initial and terminal phases of care was 5 months immediately after diagnosis of metastasis and before death, respectively. Joinpoint regression can be used to provide data-supported phase of cancer care durations, but

Ipilimumab is a fully human, anti-cytotoxic T-lymphocyte antigen-4 (CTLA-4) monoclonal antibody that has demonstrated antitumor activity in advanced melanoma. We evaluated the safety and efficacy of ipilimumab alone and in combination with dacarbazine (DTIC) in patients with unresectable, metastatic melanoma. Chemotherapy-naïve patients were randomized in this multicenter, phase II study to receive ipilimumab at 3 mg/kg every 4 weeks for four doses either alone or with up to six 5-day courses of DTIC at 250 mg/m(2)/day. The primary efficacy endpoint was objective response rate. Seventy-two patients were treated per-protocol (ipilimumab plus DTIC, n = 35; ipilimumab, n = 37). The objective response rate was 14.3% (95% CI, 4.8-30.3) with ipilimumab plus DTIC and was 5.4% (95% CI, 0.7-18.2) with ipilimumab alone. At a median follow-up of 20.9 and 16.4 months for ipilimumab plus DTIC (n = 32) and ipilimumab alone (n = 32), respectively, median overall survival was 14.3 months (95% CI, 10.2-18.8) and 11.4 months (95% CI, 6.1-15.6); 12-month, 24-month, and 36-month survival rates were 62%, 24% and 20% for the ipilimumab plus DTIC group and were 45%, 21% and 9% for the ipilimumab alone group, respectively. Immune-related adverse events were, in general, medically manageable and occurred in 65.7% of patients in the combination group versus 53.8% in the monotherapy group, with 17.1% and 7.7% ≥grade 3, respectively. Ipilimumab therapy resulted in clinically meaningful responses in advanced melanoma patients, and the results support further investigations of ipilimumab in combination with DTIC.

The immune checkpoint inhibitors ipilimumab, nivolumab, and pembrolizumab represent a substantial improvement in treating advanced melanoma but are associated with adverse events (AEs) likely related to general immunologic enhancement. To ensure that patients receive optimal benefit from these agents, prompt assessment and treatment of AEs are essential. We review the efficacy and safety profiles of these immune checkpoint inhibitors and describe guidelines for managing immune-related AEs. We also present case studies describing the management of toxicities in patients receiving immune checkpoint inhibitor therapy. These cases illustrate the importance of collecting a detailed medical history when administering immunotherapy, as this information is necessary to establish baseline, inform monitoring, and determine the etiology of symptoms. Advanced practice nurses and physician assistants are uniquely positioned to educate patients on the early recognition of AEs and have an important role in establishing appropriate monitoring and open dialogue among services.

The spectacular outcomes of the phase III trials regarding nivolumab versus ipilimumab in fully resected stage IIIB/C-IV and of the combination of dabrafenib (D) plus trametinib (T) in BRAF-mutant stage III patients demonstrate that effective treatments in advanced melanoma are also highly effective in the adjuvant setting. In 2016, an overall survival benefit with adjuvant high-dose ipilimumab was demonstrated, and the European Organisation for Research and Treatment of Cancer trial 1325 comparing pembrolizumab versus placebo will complete the picture in the early 2018. Toxicity profiles are in line with the experience in advanced melanoma, i.e. favourable for the anti-PD1 agents and for D + T and problematic for ipilimumab. The 2017 outcomes are practice changing and put an end to the use of interferon (IFN) and ipilimumab. In countries with only access to IFN, its use can be restricted to patients with ulcerated melanoma, based on the individual patient data meta-analysis recently published. Because of the results of the Melanoma Sentinel Lymph node Trial-2 (MSLT-2) trial, completion lymph node dissection (CLND) will decrease sharply, leading to a lack of optimal prognostic information. Prognosis in sentinel node-positive stage IIIA/B patients is extremely heterogeneous with 5-year survival rates varying from 90% to 40% and depends mostly on the number of positive nodes identified by CLND. This information is crucial for clinical decision-making. How to guarantee optimal staging information needs to be discussed urgently. Further improvements of adjuvant therapies will have to address all these questions as well as the exploration of neoadjuvant use of active drugs and combination approaches. Important paradigm shifts in the management of high-risk melanoma patients are upon us. Copyright © 2017 Elsevier Ltd. All rights reserved.

Clinics, prognosis and new therapeutic options in patients with mucosal melanoma: A retrospective analysis of 75 patients.

Mucosal melanomas represent a rare entity with different risk factors and molecular features compared to cutaneous melanomas. They arise most commonly from mucosal surfaces in the head/neck region, the female genital tract (FGT) and the anorectal region. The aim of this study was to evaluate clinics, prognosis, and treatment options of patients with mucosal melanoma, in particular with regard to different primary sites.We retrospectively analyzed 75 patients with mucosal melanomas diagnosed in the years 1993 to 2015 in our department. The primary melanomas were located in the head/neck region (n = 32), the FGT (n = 24), and the anorectal region (n = 19).The median age of the patients was 66 years. At initial diagnosis the primary melanoma was not completely resectable in 11 (15%) patients, 18 (24%) patients had regional lymph node metastases, and 7 (9%) patients distant metastases. During follow-up, 22 (29%) patients suffered from a local recurrence, in particular patients with primary melanoma in the head/neck region without postoperative radiotherapy. By multivariate analysis location of the primary melanoma in the head/neck area or anorectal region and presence of metastases at time of diagnosis represented poor prognostic factors for recurrence-free survival. In 62 tested individuals 7 KIT mutations were found, 2 BRAF mutations in 57 tested patients. Four patients received targeted therapies, 14 checkpoint inhibitors, 4 (1/1 on vemurafenib, 1/7 on ipilimumab, and 2/7 on PD-1 inhibitors) patients showed responses of more than 100 days duration.Mucosal melanomas are often locally advanced or metastatic at initial diagnosis, thus they require extensive staging procedures. The high rate of local recurrences in the head/neck region can be significantly reduced by postoperative radiotherapy. For the potential use of medical treatment a mutation analysis for KIT and BRAF genes should be performed. The use of new immunologic and targeted therapies has to be

Melanomas arising in areas with comparable levels of sun exposure have been shown to have similar genetic profiles. The aim of this study was to characterize the clinical features of melanoma patients according to the pattern of sun exposure: chronic, intermittent, or none. From our melanoma database, we selected 789 consecutive patients with melanoma diagnosed in our center since January 2000. Epidemiologic data, phenotype, and personal and family history of cancer were retrieved. The observed frequency of each variable was compared. Most melanoma patients presented tumors on areas exposed intermittently to sunlight. In addition, these patients presented higher numbers of common and atypical melanocytic nevi and the melanoma very frequently arose in a pre-existing nevus. The second largest group was formed by patients with tumors on areas chronically exposed to sun and that had all the clinical lesions (solar lentigines and actinic keratoses) and epidemiological characteristics typical of these areas. Finally, patients with melanomas on areas not exposed to sun were older, as occurred in the group with chronic exposure, and the diagnosis was made at more advanced stages of the disease. There are many patients who did not fit these patterns of melanoma development. Clinical and biological characterization is therefore necessary to determine alternative pathways of development in order to establish specific preventive measures.

Currently, the only therapies resulting in long term disease free intervals, high dose Interleukin-2 (IL-2) and more recently anti-CTLA-41, work through activation of the immune system. However, with both therapies the response rate is low. Advances in our knowledge of how the immune system interacts with cancer have led to a number of strategies to manipulate anti-tumor immune responses through immunotherapy. This review will focus on one avenue of immunotherapy using the transfer of T cells referred to as “Adoptive Cell Therapy” (ACT), which involves the ex vivo expansion of autologous tumor-specific T cells to large numbers that are ultimately transferred back to the patient to boost anti-tumor immunity. This approach has been shown to be effective in the treatment of virally induced cancers, as well as metastatic melanoma. Recent successes with ACT hold promise and further emphasize the tremendous potential benefit of harnessing the immune system in the fight against cancer. PMID:22484193

The development of brain metastases in patients with advanced stage melanoma is common, but the molecular mechanisms responsible for their development are poorly understood. Melanoma brain metastases cause significant morbidity and mortality and confer a poor prognosis; traditional therapies including whole brain radiation, stereotactic radiotherapy, or chemotherapy yield only modest increases in overall survival (OS) for these patients. While recently approved therapies have significantly improved OS in melanoma patients, only a small number of studies have investigated their efficacy in patients with brain metastases. Preliminary data suggest that some responses have been observed in intracranial lesions, which has sparked new clinical trials designed to evaluate the efficacy in melanoma patients with brain metastases. Simultaneously, recent advances in our understanding of the mechanisms of melanoma cell dissemination to the brain have revealed novel and potentially therapeutic targets. In this review, we provide an overview of newly discovered mechanisms of melanoma spread to the brain, discuss preclinical models that are being used to further our understanding of this deadly disease and provide an update of the current clinical trials for melanoma patients with brain metastases.

Metastatic or locally advanced unresectable melanoma carries a high morbidity and mortality. However, notable advances have been made in recent years in the systemic treatment of this disease, with the appearance of targeted therapy using tyrosine kinase inhibitors that block the mitogen activated protein kinase pathway, and of modern immunotherapy with immune-modulating monoclonal antibodies. In this paper, we provide an update of available data on new immune therapies and we review the clinical development that led to their approval for use in routine clinical practice.

The combination of temsirolimus (TEM), an MTOR inhibitor, and hydroxychloroquine (HCQ), an autophagy inhibitor, augments cell death in preclinical models. This phase 1 dose-escalation study evaluated the maximum tolerated dose (MTD), safety, preliminary activity, pharmacokinetics, and pharmacodynamics of HCQ in combination with TEM in cancer patients. In the dose escalation portion, 27 patients with advanced solid malignancies were enrolled, followed by a cohort expansion at the top dose level in 12 patients with metastatic melanoma. The combination of HCQ and TEM was well tolerated, and grade 3 or 4 toxicity was limited to anorexia (7%), fatigue (7%), and nausea (7%). An MTD was not reached for HCQ, and the recommended phase II dose was HCQ 600 mg twice daily in combination with TEM 25 mg weekly. Other common grade 1 or 2 toxicities included fatigue, anorexia, nausea, stomatitis, rash, and weight loss. No responses were observed; however, 14/21 (67%) patients in the dose escalation and 14/19 (74%) patients with melanoma achieved stable disease. The median progression-free survival in 13 melanoma patients treated with HCQ 1200mg/d in combination with TEM was 3.5 mo. Novel 18-fluorodeoxyglucose positron emission tomography (FDG-PET) measurements predicted clinical outcome and provided further evidence that the addition of HCQ to TEM produced metabolic stress on tumors in patients that experienced clinical benefit. Pharmacodynamic evidence of autophagy inhibition was evident in serial PBMC and tumor biopsies only in patients treated with 1200 mg daily HCQ. This study indicates that TEM and HCQ is safe and tolerable, modulates autophagy in patients, and has significant antitumor activity. Further studies combining MTOR and autophagy inhibitors in cancer patients are warranted.

Melanoma, a potentially lethal skin cancer, is widely thought to be immunogenic in nature. While there has been much focus on T cell-mediated immune responses, limited knowledge exists on the role of mature B cells. We describe an approach, including a cell-based ELISA, to evaluate mature IgG antibody responses to melanoma from human peripheral blood B cells. We observed a significant increase in antibody responses from melanoma patients (n = 10) to primary and metastatic melanoma cells compared to healthy volunteers (n = 10) (P<0.0001). Interestingly, we detected a significant reduction in antibody responses to melanoma with advancing disease stage in our patient cohort (n = 21) (P<0.0001). Overall, 28% of melanoma patient-derived B cell cultures (n = 1,800) compared to 2% of cultures from healthy controls (n = 600) produced antibodies that recognized melanoma cells. Lastly, a patient-derived melanoma-specific monoclonal antibody was selected for further study. This antibody effectively killed melanoma cells in vitro via antibody-mediated cellular cytotoxicity. These data demonstrate the presence of a mature systemic B cell response in melanoma patients, which is reduced with disease progression, adding to previous reports of tumor-reactive antibodies in patient sera, and suggesting the merit of future work to elucidate the clinical relevance of activating humoral immune responses to cancer.

We describe a case of mucosal malignant melanoma in the sinonasal area of a 65-year-old woman. She presented with a history of nasal obstruction and epistaxis with subsequent tenderness, facial anesthesia involving cranial nerve V2, red eye, proptosis, diplopia, and conjunctival chemosis. Computed tomography detected a nonspecific solid mass that had involved the left maxillary sinus and surrounding tissues, with extension into the nasal cavity and invasion of the orbital floor and eye muscles. Histopathologic examination of the neoplasm revealed that it was a malignant melanoma. We performed a radical hemimaxillectomy that extended to the orbit, which allowed for radical excision of the tumor. Postoperatively, the patient received adjuvant chemotherapy and radiotherapy. Mucosal melanoma in the head and neck is a rare and highly malignant neoplasm. We suggest that malignant melanoma be suspected when a small-round-cell tumor is found on light microscopy, and we confirm the usefulness of immunohistochemical investigations.

The use of routine CT imaging for surveillance in asymptomatic patients with cutaneous melanoma is controversial. We report our experience using a surveillance strategy that included CT imaging for a cohort of patients with high-risk melanoma. A total of 466 patients with high-risk cutaneous melanoma enrolled in adjuvant immunotherapy trials were followed for tumor progression by physical examination, labs, and CT imaging as defined by protocol. Evaluations were obtained at least every 6 months for year 1, every 6 months for year 2, and then annually for the remainder of the 5-year study. Time to tumor progression, sites of recurrence, and the method of relapse detection were identified. The patient cohort consisted of 115 stage II patients, 328 stage III patients, and 23 patients with resected stage IV melanoma. The medium time to progression for the 225 patients who developed tumor progression was 7 months. Tumor progression was detected by patients, physician examination or routine labs, or by CT imaging alone in 27, 14, and 59% of cases respectively. Melanoma recurrences were noted to be locoregional in 36% of cases and systemic in 64% of cases. Thirty percent of patients with locoregional relapse and 75% of patients with systemic relapse were detected solely by CT imaging. CT imaging alone detected the majority of sites of disease progression in our patients with high-risk cutaneous melanoma. This disease was not heralded by symptoms, physical examination, or blood work. Although the benefit of the early detection of advanced melanoma is unknown, this experience is relevant because of the rapid development and availability of potentially curative immunotherapies.

Background. Vascular endothelial growth factor and platelet-derived growth factor signaling in the tumor microenvironment appear to cooperate in promoting tumor angiogenesis. Patients and Methods. We conducted a phase I trial combining bevacizumab (i.v. every 2 weeks) and imatinib (oral daily). Once a recommended phase II dose combination was established, a phase II trial was initiated in patients with metastatic melanoma. A Simon 2-stage design was used with 23 patients required in the first stage and 41 patients in total should the criteria to proceed be met. We required that 50% of the patients be progression-free at 16 weeks. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and power Doppler ultrasonography were performed in patients with metastatic tumors amenable to imaging with these methods at baseline and after 4 weeks. Results. A total of 17 patients were accrued to 4 dose and combination levels. Bevacizumab 10 mg/kg every 2 weeks could be safely combined with imatinib 800 mg daily. Common toxicities included fatigue, nausea, vomiting, edema, proteinuria, and anemia, but were not commonly severe. A total of 23 patients with metastatic melanoma (48% with American Joint Commission on Cancer stage M1c; median age, 63 years) were enrolled in the first stage of phase II. The 16-week progression-free survival rate was 35%, leading to termination of phase II after the first stage. In the small subset of patients who remained on study with lesions evaluable by DCE-MRI, significant decreases in tumor vascular permeability were noted, despite early disease progression using the Response Evaluation Criteria In Solid Tumors. Conclusion. Bevacizumab and imatinib can be safely combined at the maximum doses used for each agent. We did not observe significant clinical activity with this regimen in melanoma patients. Implications for Practice: Vascular endothelial growth factor (VEGF)-targeted antiangiogenic therapy has proven clinical efficacy as a

Despite the considerable progress in understanding the biology of human cancer and technological advancement in drug discovery, treatment failure remains an inevitable outcome for most cancer patients with advanced diseases, including melanoma. Despite FDA-approved BRAF-targeted therapies for advanced stage melanoma showed a great deal of promise, development of rapid resistance limits the success. Hence, the overall success rate of melanoma therapy still remains to be one of the worst compared to other malignancies. Advancement of next-generation sequencing technology allowed better identification of alterations that trigger melanoma development. As development of successful therapies strongly depends on clinically relevant preclinical models, together with the new findings, more advanced melanoma models have been generated. In this article, besides traditional mouse models of melanoma, we will discuss recent ones, such as patient-derived tumor xenografts, topically inducible BRAF mouse model and RCAS/TVA-based model, and their advantages as well as limitations. Although mouse models of melanoma are often criticized as poor predictors of whether an experimental drug would be an effective treatment, development of new and more relevant models could circumvent this problem in the near future.

BACKGROUND Nivolumab combined with ipilimumab resulted in longer progression-free survival and a higher objective response rate than ipilimumab alone in a phase 3 trial involving patients with advanced melanoma. We now report 3-year overall survival outcomes in this trial. METHODS We randomly assigned, in a 1:1:1 ratio, patients with previously untreated advanced melanoma to receive nivolumab at a dose of 1 mg per kilogram of body weight plus ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses, followed by nivolumab at a dose of 3 mg per kilogram every 2 weeks; nivolumab at a dose of 3 mg per kilogram every 2 weeks plus placebo; or ipilimumab at a dose of 3 mg per kilogram every 3 weeks for four doses plus placebo, until progression, the occurrence of unacceptable toxic effects, or withdrawal of consent. Randomization was stratified according to programmed death ligand 1 (PD-L1) status, BRAF mutation status, and metastasis stage. The two primary end points were progression-free survival and overall survival in the nivolumab-plus-ipilimumab group and in the nivolumab group versus the ipilimumab group. RESULTS At a minimum follow-up of 36 months, the median overall survival had not been reached in the nivolumab-plus-ipilimumab group and was 37.6 months in the nivolumab group, as compared with 19.9 months in the ipilimumab group (hazard ratio for death with nivolumab plus ipilimumab vs. ipilimumab, 0.55 [P<0.001]; hazard ratio for death with nivolumab vs. ipilimumab, 0.65 [P<0.001]). The overall survival rate at 3 years was 58% in the nivolumab-plus-ipilimumab group and 52% in the nivolumab group, as compared with 34% in the ipilimumab group. The safety profile was unchanged from the initial report. Treatment-related adverse events of grade 3 or 4 occurred in 59% of the patients in the nivolumab-plus-ipilimumab group, in 21% of those in the nivolumab group, and in 28% of those in the ipilimumab group.

Our objective was to determine the clinical activity, toxicity, and immunological effects of active immunotherapy using UVB-irradiated (UVR) autologous tumor (AT) cells plus adjuvant DETOX in metastatic melanoma patients. Eligibility included nonanergic patients fully recovered after resection of 5 or more grams of metastatic melanoma. Treatment consisted of intradermal injections of 10(7) UVR-AT plus 0.25 ml of DETOX every 2 weeks x 6, then monthly. Peripheral blood mononuclear cells (PBMCs) were harvested for cytotoxicity assays, and skin testing was performed for delayed-type hypersensitivity (DTH) determinations before the first, fourth, seventh, and subsequent treatments. Forty-two patients were treated, 18 in the adjuvant setting and 24 with measurable disease. Among the latter group, there were two durable responses in soft-tissue sites and in a bone metastasis. Treatment was well tolerated. Thirty-five patients were assessable for immunological parameters; 10 of these patients, including the 2 responders, demonstrated early induction of PBMC cytotoxicity against AT cells that persisted up to 10 months on treatment before falling to background levels. In five of seven patients, the fall-off heralded progressive disease. Late induction of a weak DTH reaction to AT cells was observed in eight patients. Active immunotherapy with UVR-AT + DETOX had modest but definite clinical activity in advanced melanoma. The induction of both PBMC cytotoxicity and DTH reactivity to AT cells supported a specific systemic immune effect of treatment, although the former more closely followed disease course in this study.

Although other primary systemic cancers in patients with melanoma have been studied, there have been few focusing on acral melanomas. We assessed other primary systemic cancers in patients with acral and nonacral melanomas. We analyzed other primary cancers in 452 patients with melanoma from 1994 to 2013. Metachronous cancers were defined as those given a diagnosis more than 2 months after diagnosis of melanoma. The others were considered prechronous or synchronous cancers. Among 51 cases of other primary cancers, gastrointestinal cancer (35.3%, n = 18/51) was the most common, followed by thyroid (17.6%), lung (11.8%), and breast (5.9%). Those were more prevalent in the acral melanoma group (12.8%, n = 31/243) compared with the nonacral melanoma group (9.6%, n = 20/209). Of 23 cases of metachronous cancer, the risk was the highest in bone marrow, followed by oral cavity, bladder, colon, lung, and thyroid. Among 28 cases of prechronous or synchronous cancers, gastrointestinal tract (35.7%, n = 10/28) was the most common site, followed by thyroid (17.9%), breast (10.7%), and lung (7.1%). The study is limited by a small number of patients. Careful follow-up and imaging studies are necessary for early detection of other primary cancers and metastatic lesions in patients with melanoma.

Immunotherapy combined with surgery is associated with better survival than surgery alone in patients with advanced melanoma. This study examined the utilization of immunotherapy in relation to population characteristics and the associated survival benefit. This was a retrospective cohort study utilizing the US National Cancer Database. The study population included 6,165 adult patients (≥18 years) with stage III cutaneous melanoma (median follow-up=32 months). A total of 1,854 patients underwent immunotherapy in addition to surgery, which was associated with a survival benefit over surgery alone (hazard ratio(HR)=0.66, 95% confidence interval(CI)=0.56-0.77, p<0.001). Older age, presence of comorbidities, Medicaid/Medicare insurance, and living in a community with lower average education level were associated with less immunotherapy utilization (all p<0.05). No statistically significant racial disparity in immunotherapy usage was found (p=0.07). Compared to other demographic factors, insurance status was associated with the greatest disparities in immunotherapy utilization and mortality for patients who underwent surgery for advanced melanoma.

Ocular melanoma is a rare malignancy found in clinical practice. In this paper, we present a case of highly aggressive ocular melanoma, which was surgically removed at the Department of Ophthalmology and diagnosed at the Department of Pathology, Emergency University Hospital, Bucharest, Romania, using conventional histopathological techniques. Uveal melanoma, a subset of ocular melanoma, has a distinct behavior in comparison to cutaneous melanoma and has a widely divergent prognosis. Approximately half of patients with ocular melanoma will develop metastatic disease, predominantly with hepatic, pulmonary or cerebral location, over a 10 to 15 years period. No systemic therapy was associated with an evident clinical outcome for patients with advanced disease and overall survival rate remains poor.

The molecular mechanisms responsible for the metastatic progression of melanoma have not been fully defined yet. We have recently shown that an important role in this process is certainly played by HOX genes, whose regulation is under control of particular non-coding RNAs, some of which are present within the HOX locus. HOTAIR is the most studied among them, whose aberrant expression is associated with the metastatic progression of many malignancies. The aim of this study was to verify the role played by HOTAIR in metastatic progression of melanoma and to evaluate the circulating levels of HOTAIR in the blood of patients with metastatic melanoma. A series of melanocytic lesions were selected to evaluate the potential changes in the expression of HOTAIR during the evolution of the disease through in situ and molecular approaches. None of the benign melanocytic lesions showed the presence of HOTAIR. The staining of HOTAIR resulted very weak in the primary pT1 lesions, while it was very strong in all pairs of primary tissues and corresponding metastases. Surprisingly, we found the presence of HOTAIR in some intratumoral lymphocytes, while this positivity decreased in lymphocyte component further away from the tumor. HOTAIR was also detected in the serum of selected metastatic patients. These data allowed us to speculate on the fundamental role played by HOTAIR in tumor evolution of melanoma. Its presence in intratumoral lymphocytes might suggest that its involvement in the modulation of tumor microenvironment and the detection in the serum could be used in the management of melanoma patients. © 2017 Wiley Periodicals, Inc.

Substantial proportions of patients with metastatic melanoma develop brain metastases during the course of their disease, often resulting in significant morbidity and death. Despite recent advances with BRAF/MEK and immune-checkpoint inhibitors in the treatment of patients who have melanoma with extracerebral metastases, patients who have melanoma brain metastases still have poor overall survival, highlighting the need for further therapy options. A deeper understanding of the molecular pathways involved in the development of melanoma brain metastases is required to develop more brain-specific therapies. Here, the authors summarize the currently known preclinical data and describe steps involved in the development of melanoma brain metastases. Only by knowing the molecular background is it possible to design new therapeutic agents that can be used to improve the outcome of patients with melanoma brain metastases.

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. An electronic search was performed to identify clinical trials evaluating response to anti-PD-1 therapy with nivolumab and pembrolizumab in patients with advanced solid tumors. Thirty-eight studies were included in our analysis for a total of 7069 patients with advanced cancer treated with anti-PD-1 therapy. Responses were evaluated by unconventional response criteria in 19 trials and were observed for all cancer types but tumors with mismatch-repair deficiency and head and neck squamous cell carcinoma. Overall, 151 atypical responses were observed in 2400 patients (6%) evaluated by unconventional response criteria. The results of our systematic review highlight the clinical relevance of unconventional responses to anti-PD-1 therapy and support further investigation into the development of tools that may assist evaluation of the antitumor activity of immunotherapy.

Bim having strong pro-apoptotic effects belongs to the BH3-only proteins of the Bcl-2 protein family and contributes to survival pathways in cancer cells. We aimed to investigate Bim protein expression in cutaneous melanoma (CM). Bim protein expression was assessed by immunohistochemistry in primary and metastatic melanomas and correlated with clinical and histopathological features. The Bim immunoreactivity score of the primary melanomas investigated (4.6 ± 1.5) was significantly (P < 0.0001) higher than that observed in metastases (2.8 ± 1.1). Low Bim expression was significantly associated with primary nodular melanoma type (P = 0.005). Moreover, Bim expression was significantly inversely correlated with tumour thickness (r = -0.36; P = 0.0035), advanced stage of disease (stage III and IV; r = -0.60; P < 0.0001), disease relapse (r = -0.18; P = 0.034) and disease-related death (r = -0.19; P = 0.026). Advanced stage of disease was independently predicted by low Bim expression (P = 0.0010, odds ratio: 0.22, 95% CI: 0.10-0.56) on multivariate analysis; however, Bim was not shown to be an independent predictor for disease relapse (P = 0.40) and disease-related death (P = 0.77). Our data demonstrate that Bim protein expression is significantly inversely correlated with melanoma features that are associated with worse prognosis. We have shown that Bim protein expression in CM is an independent predictor for advanced disease confirming that this pro-apoptotic BH3-only protein might be a potent biomarker and promising therapeutic target. © 2016 European Academy of Dermatology and Venereology.

To present current melanoma diagnosis, staging, prognosis, and treatment algorithms and how recent advances in laser pump-probe microscopy will fill in the gaps in our clinical understanding. Expert opinion and significantly cited articles identified in SCOPUS were used in conjunction with a pubmed database search on Melanoma practice guidelines from the last 10 years. Significant advances in melanoma treatment have been made over the last decade. However, proper treatment algorithm and prognostic information per melanoma stage remain controversial. The next step for providers will involve the identification of patient population(s) that can benefit from recent advances. One method of identifying potential patients is through new laser imaging techniques. Pump-probe laser microscopy has been shown to correctly identify nevi from melanoma and furthermore stratify melanoma by aggressiveness. The recent development of effective adjuvant therapies for melanoma is promising and should be utilized on appropriate patient populations that can potentially be identified using pump-probe laser microscopy.

The presentations at the American Society of Clinical Oncology 2001 meeting reported or updated the results of phase I, II, and III randomized trials and also reported important meta-analyses and retrospective studies impacting on the management of patients with melanoma. In the treatment of early stage melanoma, the prognostic significance of pathologic status of sentinel lymph nodes was affirmed. With respect to regional nodal involvement (American Joint Committee on Cancer [AJCC] stage III), investigators presented the interim results of the United Kingdom randomized low-dose interferon (IFN) trial, and up-to-date meta-analyses of several IFN trials including a pooled analysis of the Eastern Cooperative Oncology Group trials evaluating interferon in the adjuvant setting. In the advanced disease setting (AJCC stage IV), several studies elucidated the pros and cons of biochemotherapy in patients with metastatic melanoma, with an emphasis on seeking to improve response in the central nervous system and durability of response in general. Thought provoking was new data regarding the potential for lovastatin to act as a chemopreventive agent for melanoma. Translational studies were presented, one supporting the importance of HLA-typing in developing targeted vaccine therapy. Finally, the results of a novel experimental melanoma vaccine were presented using autologous tumor-derived heat-shock protein peptide complex-96 (HSPPC-96).

Dacarbazine with or without oblimersen (a Bcl-2 antisense oligonucleotide) in chemotherapy-naive patients with advanced melanoma and low-normal serum lactate dehydrogenase: 'The AGENDA trial'.

In a previous large randomized, open-label study, retrospective subset analysis revealed that the addition of the Bcl-2 antisense oligonucleotide oblimersen to dacarbazine (Dac) significantly improved overall survival, progression-free survival, and the response rate in chemotherapy-naive patients with advanced melanoma and normal baseline serum lactate dehydrogenase (LDH) levels. To confirm and expand on this observation, we conducted a prospective double-blind, placebo-controlled study to determine whether oblimersen augmented the efficacy of Dac in advanced melanoma patients with low-normal baseline LDH levels. A total of 314 chemotherapy-naive patients were randomly assigned to receive Dac (1000 mg/m(2)) preceded by a 5-day continuous intravenous infusion of either oblimersen sodium (7 mg/kg/day) or placebo every 21 days for less than eight cycles. Co-primary efficacy endpoints were overall survival and progression-free survival. Response and progression of the disease were assessed by independent blinded review of computed tomography scan images. No difference in overall nor progression-free survival was observed between the Dac-oblimersen and Dac-placebo groups. Although the overall (17.2 vs. 12.1%) and durable (10.8 vs. 7.6%) response rates numerically favored Dac-oblimersen over Dac-placebo, they did not differ significantly (P=0.19 and 0.32, respectively). The incidence of hematologic adverse events, particularly thrombocytopenia and neutropenia, was higher in the Dac-oblimersen group than in the Dac-placebo group. Withdrawals from the study because of treatment-related adverse events were low (i.e. <2.5%) in both groups. The addition of oblimersen to Dac did not significantly improve overall survival nor progression-free survival in patients with advanced melanoma and low-normal levels of LDH at baseline.

Although recent advances in genetics have revealed distinct mutational profiles and molecular signaling pathways associated with Spitzoid malignant melanoma (SMM), less is known about the clinicopathologic characteristics and behavior of SMM compared with conventional melanoma. We sought to determine the clinicopathologic characteristics and mortality risk associated with SMM and conventional malignant melanoma. We conducted a retrospective study of 30 patients with SMM and 30 patients with conventional melanoma. The two groups were matched by age, gender, and depth of tumor invasion. Additional patient- and tumor-level characteristics were compared between groups and regression modeling was used to assess relative mortality risk. Unadjusted analyses of SMM and conventional malignant melanoma revealed no significant differences in clinical impression, anatomic location, mitotic rate, and presence of ulceration. Sentinel lymph node biopsy, completion lymphadenectomy, and visceral metastases did not differ between groups. Cox proportional hazards regression showed no differences in mortality between Spitzoid and conventional melanoma. Small sample size, short follow-up duration, and residual confounding may limit the accuracy and generalizability of our results. SMM and conventional malignant melanoma differ in some clinicopathologic features. We did not find a statistically significant difference in mortality between the two.

BRAF inhibitors are clinically active in patients with advanced BRAF V600 -mutant melanoma, although acquired resistance remains common. Preclinical studies demonstrated that resistance could be overcome using concurrent treatment with the HSP90 inhibitor XL888. Vemurafenib (960 mg PO BID) combined with escalating doses of XL888 (30, 45, 90 or 135 mg PO twice weekly) was investigated in 21 patients with advanced BRAF V600 -mutant melanoma. Primary endpoints were safety and determination of a maximum tolerated dose. Correlative proteomic studies were performed to confirm HSP inhibitor activity. Objective responses were observed in 15/20 evaluable patients (75%; 95% CI: 51-91%), with 3 complete and 12 partial responses. Median progression-free and overall survival were 9.2 months (95% CI: 3.8-not reached) and 34.6 months (6.2-not reached), respectively. The most common grade 3/4 toxicities were skin toxicities such as rash (n=4, 19%) and cutaneous squamous cell carcinomas (n=3, 14%), along with diarrhea (n=3, 14%). Pharmacodynamic analysis of patients' PBMCs showed increased day 8 HSP70 expression compared to baseline in the three cohorts with XL888 doses ≥45 mg. Diverse effects of vemurafenib-XL888 upon intratumoral HSP-client protein expression were noted, with the expression of multiple proteins (including ERBB3 and BAD) modulated on therapy. XL888 in combination with vemurafenib has clinical activity in patients with advanced BRAF V600 -mutant melanoma, with a tolerable side-effect profile. HSP90 inhibitors warrant further evaluation in combination with current standard-of-care BRAF plus MEK inhibitors in BRAF V600 -mutant melanoma.

Previous studies have shown that sunscreen usage, sun-protection measures and self-examination rates in patients with single primary melanomas (SPM) are similar to that in the general population. This study hypothesises that these rates would be different in a population with multiple primary melanomas (MPM). We further hypothesise that there would be a sex difference in melanoma location in patients with MPM. The objectives of this study were to determine skin protection measures, self-examinations and melanoma location in a cohort of patients with MPM. A survey was conducted on 137 patients with MPM examining their sun-protection measures, skin self-examination rates and medical and phenotypic characteristics. These data were combined with a review of their medical records to examine the patients' skin cancer history. Patients with MPM had higher rates of skin self-evaluation (74% vs 22%), sunscreen usage (70% vs 45%) and other sun-protection measures (95% vs 46%) than has been published for patients with a history of a SPM. We have also shown that women have a higher risk of developing melanomas on their arms (p < 0.01) and lower legs (p < 0.05) than men. This report showed the rates of skin self-examination, sunscreen usage and other sun-protection methods in patients with MPM is higher than in studies of patients with SPM. It also highlighted sex differences in terms of melanoma location for patients with MPM. Further studies to examine the cause of the differences in these forms of protective behaviour could help improve the utilisation of these important preventative measures in all patients. © 2015 The Australasian College of Dermatologists.

Resistance to vemurafenib can be reversible after treatment interruption: a case report of a metastatic melanoma patient.

About 40% to 60% of melanomas present BRAF mutation. Selective BRAF inhibitors such as vemurafenib and dabrafenib are currently approved for the treatment of advanced melanoma patients with BRAF mutation. The treatment-induced tumor regression occurs in the majority of patients; however, acquired resistance to BRAF inhibitors is observed in most of the patients after 6 to 7 months. After progression of the disease, the patient might be offered treatment with ipilimumab followed by chemotherapy. Subsequent lines of systemic treatment of metastatic melanoma patients do not exist.Here we report a case of a 59-year-old woman with a diagnosis of BRAF-mutant metastatic melanoma that responded to initial treatment with vemurafenib. Subsequently, after disease progression, the patient received chemotherapy. Since no clinical response to dacarbazine was observed, carboplatin with paclitaxel were applied. Transient partial response was obtained, which was followed by further disease progression. Then retreatment with vemurafenib was applied. The patient developed very short-term tumor regression and significant biochemical response (serum lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase) to the treatment. However, following 5 weeks of retreatment, the patient developed progression of the disease. Our clinical observation indicates that in melanoma patients who developed resistance to selective BRAF inhibitors, rechallenge after treatment interruption might be beneficial.

To provide appropriate therapy and follow-up to patients with malignant melanoma, proper diagnostics are of critical importance. Targeted therapy of advanced melanoma is based on the molecular genetic analyses of tumor tissue. In addition, sequencing of genes and other genetic approaches can provide insight into the origin of melanocytic tumors and can aid in distinguishing benign from malignant lesions. In this regard, spizoid neoplasms remain a challenging entity. Aside from genetic analyses of tumor tissue, immunohistochemistry remains an essential tool in melanoma diagnostics and TNM classification. With new immunotherapies being approved for advanced melanoma, immunohistochemistry to determine PD-L1 expression has gained clinical interest. While PD-L1 expression is associated with response to PD-1 blockade, a substantial number of patients without PD-L1 expression can still experience tumor remission upon treatment. In this review, current and future developments in melanoma diagnostics with regard to molecular genetics and immunohistochemistry are summarized. The utilization of such analyses in clinical decision making is also discussed.

Background This report provides a survival update at a follow-up of >5 years (5.5–6 years) for patients with advanced melanoma who previously received ipilimumab in phase II clinical trials. Safety and efficacy data following ipilimumab retreatment are also reported. Patients and methods Patients who previously received ipilimumab 0.3, 3, or 10 mg/kg in one of six phase II trials (CA184-004, CA184-007, CA184-008, CA184-022, MDX010-08, and MDX010-15) were eligible to enroll in the companion study, CA184-025. Upon enrollment, patients initially received ipilimumab retreatment, extended maintenance therapy, or were followed for survival only. Overall survival (OS) rates were evaluated in patients from studies CA184-004, CA184-007, CA184-008, and CA184-022. Safety and best overall response during ipilimumab retreatment at 10 mg/kg were assessed in study CA184-025. Results Five-year OS rates for previously treated patients who received ipilimumab induction at 0.3, 3, or 10 mg/kg were 12.3%, 12.3%–16.5%, and 15.5%–28.4%, respectively. Five-year OS rates for treatment-naive patients who received ipilimumab induction at 3 or 10 mg/kg were 26.8% and 21.4%–49.5%, respectively. Little to no change in OS was observed from year 5 up to year 6. The objective response rate among retreated patients was 23%. Grade 3/4 immune-related adverse events occurred in 25%, 5.9%, and 13.2% of retreated patients who initially received ipilimumab 0.3, 3, and 10 mg/kg, with the most common being observed in the skin (4.2%, 2.9%, 3.8%) and gastrointestinal tract (12.5%, 2.9%, 3.8%), respectively. Conclusions At a follow-up of 5–6 years, ipilimumab continues to demonstrate durable, long-term survival in a proportion of patients with advanced melanoma. In some patients, ipilimumab retreatment can re-establish disease control with a safety profile that is comparable with that observed during ipilimumab induction. Further studies are needed to determine the contribution of ipilimumab

The reported frequencies of associations between primary cutaneous melanomas and melanocytic nevi vary widely between 4% and 72%. However, earlier histopathologic studies were limited by their retrospective design and did not assess the influence of important patient-related risk factors. To identify the frequency of nevus-associated melanomas and correlate patient- and melanoma-related factors. A prospective, single-center, observational study with systematic documentation of melanoma risk factors, clinical and dermoscopic criteria of excised lesions, and results of histopathologic examination was conducted at a university-based dermatology clinic. Participants included 832 patients at high risk for developing melanoma. Evaluation was performed at regular intervals between April 1, 1997, and May 31, 2012, and data analysis was conducted between September 1, 2012, and December 31, 2013. Assessment of the frequency of nevus-associated melanoma and the influence of patient- and melanoma-related factors on their manifestation. During the study, 190 melanomas (81 [42.6%] in situ and 109 [57.4%] invasive) were diagnosed in 113 of the 832 patients (13.6%); there were 42 women (37.2%) and 71 men (62.8%). The median (SD) Breslow thickness of invasive melanomas was 0.42 (0.43) mm. Histopathologic examination revealed remnants of melanocytic nevi in 103 melanomas (54.2%). Most nevus-associated melanomas were found on the trunk (67 [65.1%]); however, statistical significance for the localization was not present (P = .06). In univariate analyses, reported as odds ratios (95% CIs), nevus-associated melanomas were found significantly more frequently in patients of lower melanoma risk (risk group 1 [>50 common and/or ≤ 3 atypical nevi], 2.75 [1.14-6.64]; P = .02), with more than 100 nevi (1.63 [1.02-3.60]; P = .04), or with the diagnosis of in situ melanoma (14.01 [6.14-31.96]; P < .001). In contrast, nevus-associated melanomas were found significantly less frequently

By the recent introduction of molecular targeting drugs against BRAF mutation and immune checkpoint inhibitors, the prognosis of patients with melanoma in advanced stage is now improving, but still in the minority. Mucosal melanoma lacks the BRAF mutations, and hence conventional chemotherapeutic regimens must be improved. We have conventionally used dacarbazine (DTIC) for patients with metastatic mucosal melanoma. However, the efficacy of DTIC in patients with metastatic mucosal melanoma has been limited. Therefore, we explored other possibilities to improve the prognosis of patients suffering from metastatic mucosal melanoma. In this communication, we present a retrospective analysis of the sequential combination chemotherapy of DTIC with carboplatin and paclitaxel (CP) for metastatic mucosal melanoma of nasal cavity and paranasal sinuses. The objective response rate of seven patients is 14.3% by RECIST 1.1 and the overall survival (OS) is 12.5 months. These data indicate that the sequential combination chemotherapy of DTIC with CP could be an option for patients with metastatic mucosal melanoma of nasal cavity and paranasal sinuses who are currently ending into dismal prognosis.

Recent technological advances in single-cell genomics make it possible to analyze cellular heterogeneity of tumor samples. Here, we applied single-cell RNA-seq to measure the transcriptomes of 307 single cells cultured from three biopsies of three different patients with a BRAF/NRAS wild type, BRAF mutant/NRAS wild type and BRAF wild type/NRAS mutant melanoma metastasis, respectively. Analysis based on self-organizing maps identified sub-populations defined by multiple gene expression modules involved in proliferation, oxidative phosphorylation, pigmentation and cellular stroma. Gene expression modules had prognostic relevance when compared with gene expression data from published melanoma samples and patient survival data. We surveyed kinome expression patterns across sub-populations of the BRAF/NRAS wild type sample and found that CDK4 and CDK2 were consistently highly expressed in the majority of cells, suggesting that these kinases might be involved in melanoma progression. Treatment of cells with the CDK4 inhibitor palbociclib restricted cell proliferation to a similar, and in some cases greater, extent than MAPK inhibitors. Finally, we identified a low abundant sub-population in this sample that highly expressed a module containing ABC transporter ABCB5, surface markers CD271 and CD133, and multiple aldehyde dehydrogenases (ALDHs). Patient-derived cultures of the BRAF mutant/NRAS wild type and BRAF wild type/NRAS mutant metastases showed more homogeneous single-cell gene expression patterns with gene expression modules for proliferation and ABC transporters. Taken together, our results describe an intertumor and intratumor heterogeneity in melanoma short-term cultures which might be relevant for patient survival, and suggest promising targets for new treatment approaches in melanoma therapy.

Background: The characterization of the genes encoding melanoma-associated antigens MART-1 or gp100, recognized by T cells, has opened new possibilities for the development of immunization strategies for patients with metastatic melanoma. With the use of recombinant adenoviruses expressing either MART-1 or gp100 to immunize patients with metastatic melanoma, we evaluated the safety, immunologic, and potential therapeutic aspects of these immunizations. Methods: In phase I studies, 54 patients received escalating doses (between 107 and 1011 plaque-forming units) of recombinant adenovirus encoding either MART-1 or gp100 melanoma antigen administered either alone or followed by the administration of interleukin 2 (IL-2). The immunologic impact of these immunizations on the development of cellular and antibody reactivity was assayed. Results: Recombinant adenoviruses expressing MART-1 or gp100 were safely administered. One of 16 patients with metastatic melanoma receiving the recombinant adenovirus MART-1 alone experienced a complete response. Other patients achieved objective responses, but they had received IL-2 along with an adenovirus, and their responses could be attributed to the cytokine. Immunologic assays showed no consistent immunization to the MART-1 or gp100 transgenes expressed by the recombinant adenoviruses. High levels of neutralizing antibody were found in the pretreatment sera of the patients. Conclusions: High doses of recombinant adenoviruses could be safely administered to cancer patients. High levels of neutralizing antibody present in patients' sera prior to treatment may have impaired the ability of these viruses to immunize patients against melanoma antigens. PMID:9862627

Melanoma is an extremely rare tumor in Asia. This retrospective study aimed to identify the clinical characteristics and prognostic factors of metastatic melanoma patients at Tianjin Medical University Cancer Hospital over the last 30 years. Survival analysis was performed with Kaplan-Meier, log-rank test, and multivariate Cox regression method using SPSS 19.0 software. The 1-, 2-, and 5-year survival rates of metastatic melanoma patients were 52, 32, and 16 %, respectively. Median overall survival (OS) was 13.5 months, median progression-free survival (PFS) 9.0 months, and median disease-free survival 20.3 months. Furthermore, patients with a single metastatic site achieved better OS and PFS than those with two or more metastatic lesions (OS 21.6 vs. 8.9 months, P < 0.001; PFS 11.3 vs. 7.1 months, P < 0.001). Survival times of patients with visceral metastases were the shortest (OS 8.5 months; PFS 7.5 months). Specifically, patients with primary mucosal lesions had a worse OS (9.7 months) and PFS (6.8 months) than those with acral (19.2 and 15.6 months, respectively) or non-acral primary lesions (11.8 and 11.1 months, respectively). The treatment of advanced melanoma was unitary, and prognoses of patients with metastatic melanoma in China were poor. Visceral metastasis, multiple metastatic sites, and primary mucosal lesions were significant predictors of survival of patients with metastatic melanoma. Those with primary mucosal lesions had significantly worse survivals than those with primary cutaneous lesions. More active involvement in clinical studies and more feedback on various treatment options are required.

Mucosal melanoma is an extremely rare and aggressive malignancy that often remains undetected until it reaches an advanced stage, when effective treatment options are limited. The activity and safety of ipilimumab were assessed in an Expanded Access Programme (EAP) that included patients with metastatic, mucosal melanoma. Ipilimumab was available upon physician request for patients aged ⩾16years with stage III (unresectable) or IV skin, ocular or mucosal melanoma, who had failed or did not tolerate previous treatments and had no other therapeutic option available. Patients received ipilimumab 3mg/kg every 3weeks for four doses. Patients with stable disease or an objective response to ipilimumab were eligible for retreatment upon disease progression. Tumour assessments were conducted at baseline and week 12 using immune-related response criteria. Patients were monitored for adverse events (AEs), including immune-related AEs, within 3 to 4days of each scheduled visit. Of 855 patients participating in the EAP in Italy, 71 (8%) had metastatic, mucosal melanoma. With a median follow-up of 21.8months, the response rate was 12% and the immune-related disease control rate was 36%. Median progression-free survival and overall survival were 4.3 and 6.4months, respectively. In total, 34% of patients reported treatment-related AEs of any grade, which were grade 3 or 4 in 9% of patients. AEs were generally manageable as per protocol-specific guidelines. Ipilimumab may be a feasible treatment option in pretreated patients with metastatic mucosal melanoma, and warrants further investigation in prospective clinical trials.

Recent clinical trials have shown that pembrolizumab significantly prolonged progression-free survival and overall survival compared with ipilimumab in ipilimumab-naïve patients with unresectable or metastatic melanoma. However, there has been no published evidence on the cost-effectiveness of pembrolizumab for this indication. To assess the long-term cost-effectiveness of pembrolizumab versus ipilimumab in ipilimumab-naïve patients with unresectable or meta-static melanoma from a U.S. integrated health system perspective. A partitioned-survival model was developed, which divided overall survival time into progression-free survival and postprogression survival. The model used Kaplan-Meier estimates of progression-free survival and overall survival from a recent randomized phase 3 study (KEYNOTE-006) that compared pembrolizumab and ipilimumab. Extrapolation of progression-free survival and overall survival beyond the clinical trial was based on parametric functions and literature data. The base-case time horizon was 20 years, and costs and health outcomes were discounted at a rate of 3% per year. Clinical data-including progression-free survival and overall survival data spanning a median follow-up time of 15 months, as well as quality of life and adverse event data from the ongoing KEYNOTE-006 trial-and cost data from public sources were used to populate the model. Costs included those of drug acquisition, treatment administration, adverse event management, and disease management of advanced melanoma. The incremental cost-effectiveness ratio (ICER) expressed as cost difference per quality-adjusted life-year (QALY) gained was the main outcome, and a series of sensitivity analyses were performed to test the robustness of the results. In the base case, pembrolizumab was projected to increase the life expectancy of U.S. patients with advanced melanoma by 1.14 years, corresponding to a gain of 0.79 discounted QALYs over ipilimumab. The model also projected an average

Sentinel lymph node status is a major prognostic marker in locally invasive cutaneous melanoma. However, this procedure is not always feasible, requires advanced logistics and carries rare but significant morbidity. Previous studies have linked markers of tumour biology to patient survival. In this study, we aimed to combine the predictive value of established biomarkers in addition to clinical parameters as indicators of survival in addition to or instead of sentinel node biopsy in a cohort of high-risk melanoma patients. Patients with locally invasive melanomas undergoing sentinel lymph node biopsy were ascertained and prospectively followed. Information on mortality was validated through the National Death Index. Immunohistochemistry was used to analyse proteins previously reported to be associated with melanoma survival, namely Ki67, p16 and CD163. Evaluation and multivariate analyses according to REMARK criteria were used to generate models to predict disease-free and melanoma-specific survival. A total of 189 patients with available archival material of their primary tumour were analysed. Our study sample was representative of the entire cohort (N = 559). Average Breslow thickness was 2.5 mm. Thirty-two (17%) patients in the study sample died from melanoma during the follow-up period. A prognostic score was developed and was strongly predictive of survival, independent of sentinel node status. The score allowed classification of risk of melanoma death in sentinel node-negative patients. Combining clinicopathological factors and established biomarkers allows prediction of outcome in locally invasive melanoma and might be implemented in addition to or in cases when sentinel node biopsy cannot be performed. © 2016 UICC.

Immune-checkpoint blockers (ICBs) significantly prolong overall survival (OS) in patients with advanced melanoma. Limited data are available on the efficacy and clinical benefit in patients with melanoma brain metastases (MBMs). The aim of this study was to determine whether ICB is active in an unselected cohort treated of patients with known brain metastases and if disease control correlates with the survival. A total of 385 patients with metastatic malignant melanoma treated with ICB as monotherapy between 2005 and 2017 in two tertiary referral centres were included. Patient records were searched for the development of brain metastases. Demographic and clinical data of all patients were collected retrospectively. We identified 177 patients with MBM who received ICBs (ipilimumab, nivolumab, pembrolizumab). Patients with and without brain metastases received similar ICB regimens. Prognosis was inferior in patients with brain metastases; patients with >1 brain metastasis showed even poorer survival. For extracranial (ec) metastases, disease control was associated with improved survival. However, when comparing patients with intracranial (ic) disease control during immunotherapy to patients with ic disease progression, no difference in OS could be observed. In our study, ec disease control was the dominant predictive factor for OS in both patients with or without melanoma brain metastases. These data indicate that clinical trials in melanoma patients with brain metastases should address end-points such as symptom control, quality of life or OS in addition to ic response rates.

One Step Melanoma Surgery for Patient with Thick Primary Melanomas: "To Break the Rules, You Must First Master Them!"

PubMed

Tchernev, Georgi

2018-02-15

We present to the attention of the medical, dermatological and oncosurgical community data that serves to indicate the indispensability of optimisation of the algorithm and recommendations for diagnosis and surgical treatment of cutaneous melanoma. These recommendations could be referred to different subgroups of patients in different clinical stages as well as to patients with different initial characterisation (histological morphology) of the primary tumours. One step surgery is not a myth, even more, it could prove to be one of the best solutions for some patient collectives with advanced stages of melanoma. We present a case of a 74 - year old patient with a congenital medium sized melanocytic nevus, located directly above the lateral part of the elbow joint. In one month and a half, an achromatic nodular formation evolves with a diameter of 2.7 x 2.3 cm, prominent over the skin level, painful by palpation and spontaneously bleeding. By the anamnestic, clinical and dermoscopic findings the patient was diagnosed with nodular melanoma associated with a congenital medium sized melanocytic nevus. A primary excision with a field of safety 0.5 cm in all directions was performed. After confirmation of the primary diagnosis (tumour thickness 8 mm with no ultrasonographic detection of enlarged lymph nodes), seven days later are - excision was performed with an additional field of surgical safety of 1.5 cm in all directions. In this case remains unclear the following question: For what reason a preoperative high - frequent ultrasonography (HFUS) is not recommended to be used as it will allow only one surgical excision with the elimination of a tumour with a safety field of 2cm in all directions? The enigma about the obstacles preventing such a rational optimisation of the current diagnostic and therapeutic algorithm in patients with melanomas remains unresolved. One step surgery for cutaneous melanoma is widely used in many countries although it continues to be

A history of melanoma within the preceding 5 years is commonly considered a contraindication to solid organ transplantation. We investigated how a pretransplant history of melanoma impacts patient survival and melanoma recurrence. Institutional Review Board approval was obtained, and Duke's retrospective database was used to identify 4552 patients who underwent a solid organ transplant at Duke University from 1 January 2001 to 31 December 2016. Data with regard to the transplant, melanoma characteristics, rejection episodes, and survival were recorded. Of 4552 patients who underwent a solid organ transplant, 12 (0.3%) had a history of melanoma before transplant (six with melanoma in situ and six with stage I disease). The median time between melanoma diagnosis and transplant was 4.13 years (range: 1.1-13.3 years). The study cohort consisted of four liver transplants, four lung transplants, one kidney transplant, one heart transplant, one small bowel transplant, and one multivisceral transplant. At the median follow-up time of 2.8 years, 10 (83.3%) patients were alive. In nonmelanoma cohorts, the 3-year survival is 70% for thoracic transplants, 78% for liver transplants, and 88% for kidney transplants. In well-selected patients with a history of early-stage melanoma and an appropriate time interval between melanoma treatment and transplant, post-transplant outcomes are favorable.

The mutational status of stage III and IV melanomas should be recognized in order to allow for targeted therapies. The aim of our study was the characterization of BRAF, NRAS and C-KIT melanoma patients, in order to define their optimal management. Between 1991 and 2015, 63 mutated melanoma patients were treated and monitored during their diagnostic and therapeutic management at a single institution. BRAF-mutated melanoma patients were the most common, representing 70% of the study population, while NRAS- and C-KIT-mutated melanoma represented 19% and 11% respectively. BRAF-mutated melanomas were mostly located at sites of intermittent sun exposure, and were associated with higher Breslow thickness and an increased number of mitosis. NRAS mutated melanoma were mainly observed in chronic sun-damaged areas and had a negative prognostic value, with shorter time to progression and a high incidence of central nervous system involvement. C-KIT mutated melanoma were located at acral and mucosal sites. Overall survival observed in the three groups of patients revealed wide differences. BRAF, NRAS and C-KIT melanomas constitute distinct clinico-pathological entities. BRAF-mutated melanoma benefit from both anti-BRAF and anti-MEK targeted therapies while triple-negative melanomas could benefit from novel anti-CTLA-4 and anti-PD-L1 immunotherapeutic approaches.

Active specific immunotherapy of cancer requires an efficient induction and effector phase. The induction covers potent activation of anti-tumor response, whereas effector breaks the immunosuppression. We report efficacy of therapeutic melanoma vaccine (AGI-101H) used alone in advanced disease as a candidate for further combined treatment. In adjuvant setting in patients with resected metastases AGI-101H combined with surgery of recurring disease demonstrated long-term survival. Seventy-seven patients with nonresectable melanoma (8% IIIB, 21% IIIC, 71% IV) were enrolled. AGI-101H was administered 8× every 2 weeks, and then every month. At progression, maintenance was continued or induction was repeated and followed by maintenance. Median follow-up was 139.3 months. The median overall survival (OS) was 17.3 months; in patients with WHO 0-1 was 20.3 months. Complete response (CR) and partial response (PR) were observed in 19.4% and 9% of pts. Disease control rate was 54.5% of pts. The median CR+PR duration was 32 months. Reinduction was performed in 36.3% patients following disease progression with 46.6% of CR+PR. No grade 3/4 adverse events were observed. Treatment with AGI-101H of melanoma patients is safe and effective. AGI-101H is a good candidate for combinatorial treatment with immune check-points inhibitors or tumor hypoxia normalizators. EudraCT Number 2008-003373-40.

Although psychosocial distress has been evaluated well in cancer entities like breast or prostate cancer, its impact on melanoma patients still needs to be characterized. The objectives of this study were to (i) evaluate psychosocial distress in melanoma patients using an expert rating instrument [basic documentation for psycho-oncology short version (PO-Bado SF)]; (ii) determine associated demographic and clinical variables; and (iii) assess the acceptance of using PO-Bado SF as a routine procedure in a skin cancer unit. A cross-sectional group of 696 melanoma patients was recruited. During the routine contact, doctors assessed the patients subjective distress using PO-Bado SF. Sociodemographic data, tumour data, treatment and the course of the disease were extracted from the patients' charts. PO-Bado SF was completed in 688 of 696 (99%) participating patients, revealing a high acceptance. In 51 (7%) patients, the PO-Bado SF cut-off score indicated the potential need of psychosocial support. Patients with previous or ongoing radiotherapy, a history of major surgery due to organ metastases, younger age and shorter time since diagnosis were considered significantly more distressed than patients without these criteria. Patients were most distressed by suffering from anxiety/worries and/or tensions. In younger patients emotional variables and other problems like social or family problems were deemed more relevant while functional limitations in daily living were reasons for higher distress in older patients. PO-Bado SF is a useful, well-accepted, practical and economic screening tool to identify distressed melanoma patients. Although most melanoma patients seem to cope well with their disease, special attention should be given to young patients in the first years after initial diagnosis and to patients with advanced disease, radiotherapy and major surgery due to their disease. Combination of expert rating tools with self-report screening instruments could further

Importance NRAS and BRAF mutations in melanoma inform current treatment paradigms but their role in survival from primary melanoma has not been established. Identification of patients at high risk of melanoma-related death based on their primary melanoma characteristics before evidence of recurrence could inform recommendations for patient follow-up and eligibility for adjuvant trials. Objective To determine tumor characteristics and survival from primary melanoma by somatic NRAS and BRAF status. Design, Setting, and Participants A population-based study with median follow-up of 7.6 years for 912 patients with first primary cutaneous melanoma analyzed for NRAS and BRAF mutations diagnosed in the year 2000 from the United States and Australia in the Genes, Environment and Melanoma Study and followed through 2007. Main Outcomes and Measures Tumor characteristics and melanoma-specific survival of primary melanoma by NRAS and BRAF mutational status. Results The melanomas were 13% NRAS+, 30% BRAF+, and 57% with neither NRAS nor BRAF mutation (wildtype). In a multivariable model including clinicopathologic characteristics, NRAS+ melanoma was associated (P<.05) with mitoses, lower tumor infiltrating lymphocyte (TIL) grade, and anatomic site other than scalp/neck and BRAF+ melanoma was associated with younger age, superficial spreading subtype, and mitoses, relative to wildtype melanoma. There was no significant difference in melanoma-specific survival for melanoma harboring mutations in NRAS (HR 1.7, 95% CI, 0.8–3.4) or BRAF (HR, 1.5, 95% CI, 0.8–2.9) compared to wildtype melanoma adjusted for age, sex, site, AJCC tumor stage, TIL grade, and study center. However, melanoma-specific survival was significantly poorer for higher risk (T2b or higher stage) tumors with NRAS (HR 2.9; 95% CI 1.1–7.7) or BRAF (HR 3.1; 95% CI 1.2–8.5) mutations but not for lower risk (T2a or lower) tumors (P=.65) adjusted for age, sex, site, AJCC tumor stage, TIL grade, and study center

The recent years have seen significant progress in the development of systemic therapies to treat patients with advanced melanoma. Use of these new treatment modalities, which include immune checkpoint inhibitors and small molecule BRAF inhibitors, lead to increased overall survival and better outcomes. Although revolutionary, these therapies are often less effective against melanoma brain metastases, and frequently the CNS is the major site of treatment failure. The development of brain metastases remains a serious complication of advanced melanoma that is associated with significant morbidity and mortality. New approaches to both prevent the development of brain metastases and treat established disease are urgently needed. In this review we will outline the mechanisms underlying the development of melanoma brain metastases and will discuss how new insights into metastasis biology are driving the development of new therapeutic strategies. Finally, we will describe the latest data from the ongoing clinical trials for patients with melanoma brain metastases. Copyright © 2018 Elsevier Inc. All rights reserved.

Fever as a factor contributing to long-term survival in a patient with metastatic melanoma: A case report.

2018-06-01

Malignant melanoma is a cancer that arises from pigment cells in the skin called melanocytes. The long-term survival of a patient with advanced melanoma is rare. We present a unique case of a female patient who has suffered from malignant melanoma for more than 13 years. The disease progressed quickly, and 19 months after diagnosis, the patient was classified as having stage IV melanoma. After several years, the patient had several episodes of fever that were not deliberately treated with medication. After each episode of fever, the patient observed the disappearance of tumours, which was confirmed by medical examination. Interestingly, since her initial diagnosis, the patient has refused most of the proposed medical treatments. Consequently, only some of the surgical procedures were performed. Currently, despite the initially poor prognosis, the patient only suffers symptoms that are the result of surgical resection of brain metastases. Most of her malignant tumours either disappeared or have stabilized without further growth. The onset of fever has altered the typical and unfavourable course of melanoma, causing remission or at least stabilization. This observation, in accordance with others in this field, suggests that fever in cancer patients should not be treated immediately, but should be allowed to develop under the care of a physician.

2013-01-01

Recent insights into the genetic and somatic aberrations have initiated a new era of rapidly evolving targeted and immune-based treatments for melanoma. After decades of unsuccessful attempts to finding a more effective cure in the treatment of melanoma now we have several drugs active in melanoma. The possibility to use these drugs in combination to improve responses to overcome the resistance, to potentiate the action of immune system with the new immunomodulating antibodies, and identification of biomarkers that can predict the response to a particular therapy represent new concepts and approaches in the clinical management of melanoma. The third “Melanoma Research: “A bridge from Naples to the World” meeting, shortened as “Bridge Melanoma Meeting” took place in Naples, December 2 to 4th, 2012. The four topics of discussion at this meeting were: advances in molecular profiling and novel biomarkers, combination therapies, novel concepts toward integrating biomarkers and therapies into contemporary clinical management of patients with melanoma across the entire spectrum of disease stage, and the knowledge gained from the biology of tumor microenvironment across different tumors as a bridge to impact on prognosis and response to therapy in melanoma. This international congress gathered more than 30 international faculty members who in an interactive atmosphere which stimulated discussion and exchange of their experience regarding the most recent advances in research and clinical management of melanoma patients.

Subungual melanoma is a rare subtype of cutaneous melanoma that arises from the structures of the nail apparatus. It presents most commonly in older patients and at an advanced stage. A retrospective review of all patients with subungual melanoma in a single institution over a 15-year period was performed. In total, 54 patients were included (26 males, average age 62.9 years), of which 28 cases involved the upper limb. Median tumour thickness was 4.5 mm. Eighteen patients had lymph node metastasis at diagnosis, including 11 of 36 patients with positive sentinel lymph node biopsy. Median survival was 4.6 years. Subungual melanoma has a poor prognosis that is strongly associated with presence of nodal disease at diagnosis. Sentinel lymph node biopsy should be considered to determine stage and prognosis.

Melanoma is increasing in incidence and remains a major public health threat. Although the disease may be curable when identified early, advanced melanoma is characterized by widespread metastatic disease and a median survival of less than 10 months. In recent years, however, major advances in our understanding of the molecular nature of melanoma and the interaction of melanoma cells with the immune system have resulted in several new therapeutic strategies that are showing significant clinical benefit. Current therapeutic approaches include surgical resection of metastatic disease, chemotherapy, immunotherapy, and targeted therapy. Dacarbazine, interleukin-2, ipilimumab, and vemurafenib are now approved for the treatment of advanced melanoma. In addition, new combination chemotherapy regimens, monoclonal antibodies blocking the programmed death-1 (PD-1)/PD-ligand 1 pathway, and targeted therapy against CKIT, mitogen-activated protein/extracellular signal-regulated kinase (MEK), and other putative signaling pathways in melanoma are beginning to show promise in early-phase clinical trials. Further research on these modalities alone and in combination will likely be the focus of future clinical investigation and may impact the outcomes for patients with advanced melanoma. PMID:23677693

Effective Treatment of Advanced Human Melanoma Metastasis in Immunodeficient Mice Using Combination Metronomic Chemotherapy Regimens

Statement of translational relevance Despite significant efforts over the last two decades aimed at improving the efficacy of standard treatment (maximum tolerated dose (MTD) of dacarbazine), there has been no significant increase in the median survival of patients suffering from metastatic melanoma. Given the lack of success achieved, a rethinking of alternative treatment strategies is needed. Using preclinical models of advanced melanoma metastasis, we show that metronomic chemotherapeutic combinations results in improved survival, which is achieved with minimal toxicity. These results compare favorably with minimal effectiveness achieved by MTD dacarbazine therapy (alone or in combination with other chemotherapeutic agents or a VEGFR-blocking antibody), often accompanied by higher toxicity. Successes in preclinical setting of metastatic breast cancer have led to a clinical trial to examine the efficacy of metronomic therapy. A similar extension of the metronomic chemotherapeutic combinations presented here into the clinical setting of melanoma metastasis may be warranted. Purpose The development of effective therapeutic approaches for treatment of metastatic melanoma remains an immense challenge. Present therapies offer minimal benefit. While dacarbazine (DTIC) chemotherapy remains the standard therapy, it mediates only low response rates, usually of short duration, even when combined with other chemotherapeutic agents. Thus, new therapeutic strategies are urgently needed. Experimental design Using a newly developed preclinical model, we evaluated the efficacy of various doublet metronomic combination chemotherapy against established, advanced melanoma metastasis and compared these to the standard maximum tolerated dose (MTD) DTIC (alone or in combination with chemotherapeutic agents or VEGFR-blocking antibody) Results Whereas MTD DTIC therapy did not cause significant improvement in median survival, a doublet combination of low-dose metronomic (LDM) vinblastine

Molecular pathways regulating melanoma initiation and progression are potential targets of therapeutic development for this aggressive cancer. Identification and molecular analysis of these pathways in patients has been primarily restricted to targeted studies on individual proteins. Here, we report the most comprehensive analysis of formalin-fixed paraffin-embedded human melanoma tissues using quantitative proteomics. From 61 patient samples, we identified 171 proteins varying in abundance among benign nevi, primary melanoma, and metastatic melanoma. Seventy-three percent of these proteins were validated by immunohistochemistry staining of malignant melanoma tissues from the Human Protein Atlas database. Our results reveal that molecular pathways involved with tumor cell proliferation, motility, and apoptosis are mis-regulated in melanoma. These data provide the most comprehensive proteome resource on patient melanoma and reveal insight into the molecular mechanisms driving melanoma progression.

Mucosal melanomas represent about 1% of all melanoma cases and classically have a worse prognosis than cutaneous melanomas. Due to the rarity of mucosal melanomas, only limited clinical studies with metastatic mucosal melanoma are available. Mucosal melanomas most commonly contain mutations in the gene CKIT, and treatments have been investigated using targeted therapy for this gene. Mutations in mucosal melanoma are less common than in cutaneous or uveal melanomas and occur in descending order of frequency as: CKIT (20%), NRAS (5%) or BRAF (3%). Mutations in G-alpha proteins, which are associated with activation of the mitogen-activated protein kinase pathway, have not been reported in mucosal melanomas. These G-alpha protein mutations occur in the genes GNAQ and GNA11 and are seen at a high frequency in uveal melanomas, those melanomas that begin in the eye. A 59-year old Caucasian male was diagnosed with a mucosal melanoma after evaluation for what was thought to be a hemorrhoid. Molecular analysis of the tumor revealed a GNAQ mutation. Ophthalmologic exam did not disclose a uveal melanoma. Here we report, to our knowledge, the first known case of GNAQ mutation in a patient with metastatic mucosal melanoma.

To explore health-related quality of life (HRQoL) in recurrence-free melanoma patients, with a focus on the association between melanoma-related limb lymphoedema and HRQoL. HRQoL was evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the breast cancer module (EORTC QLQ-BR23) subscales body image and future perspective, the Functional Assessment for Cancer Therapy-General subscale social/family well-being and the Hospital Anxiety and Depression Scale. Data were analysed using linear and ordinal logistic regression adjusting for age and gender. A total of 431 melanoma patients who had undergone wide local excision and axillary or inguinal sentinel lymph node biopsy (SLNB) and/or complete lymph node dissection (CLND) participated. No patients had had recurrence of the disease or had received adjuvant radiotherapy. The HRQoL scores improved with time after surgery. Melanoma-related limb lymphoedema was present in 109 patients (25%). Patients with lymphoedema had significantly worse HRQoL scores in the EORTC QLQ-C30 subscales global health status/quality of life, role and social functioning, fatigue, pain and financial difficulties, as well as in the QLQ-BR23 body image subscale. No associations were found between the limb affected (upper or lower limb), clinical stage of lymphoedema, duration of lymphoedema or type of surgery (SLNB or CLND) and HRQoL. We found an interaction with age and gender in the associations between lymphoedema and HRQoL: younger patients and women with lymphoedema had worse social functioning and women had significantly more impaired body image. The negative impact of melanoma-related limb lymphoedema on HRQoL emphasises the importance of developing strategies for increasing awareness and improving prevention and treatment of lymphoedema.

To assess the clinical and biological activity of the association of bevacizumab and fotemustine as first-line treatment in advanced melanoma patients. Previously untreated, metastatic melanoma patients (n = 20) received bevacizumab (at 15 mg/kg every 3 weeks) and fotemustine (100 mg/m² by intravenous administration on days 1, 8, and 15, repeated after 4 weeks) in a multicenter, single-arm, open-label, phase II study. Primary endpoint was the best overall response rate; other endpoints were toxicity, time to progression (TTP), and overall survival (OS). Serum cytokines, angiogenesis, and lymphangiogenesis factors were monitored by multiplex arrays and by in vitro angiogenesis assays. Effects of fotemustine on melanoma cells, in vitro, on vascular endothelial growth factor (VEGF)-C release and apoptosis were assessed by ELISA and flow cytometry, respectively. One complete response, 2 partial responses (PR), and 10 patients with stable disease were observed. TTP and OS were 8.3 and 20.5 months, respectively. Fourteen patients experienced adverse events of toxicity grade 3-4. Serum VEGF-A levels in evaluated patients (n = 15) and overall serum proangiogenic activity were significantly inhibited. A significant reduction in VEGF-C levels was found in several post-versus pretherapy serum samples. In vitro, fotemustine inhibited VEGF-C release by melanoma cells without inducing significant cell death. Serum levels of interleukin (IL)-10 and IL-12p70 showed the highest levels in sera of PR patients, compared with patients with stable or progressive disease whereas IL-23 showed the opposite pattern. The combination of bevacizumab plus fotemustine has clinical activity in advanced melanoma and promotes systemic modulation of angiogenesis and lymphangiogenesis factors. ©2010 AACR.

Early Detection of New Melanomas by Patients With Melanoma and Their Partners Using a Structured Skin Self-examination Skills Training Intervention

IMPORTANCE More than 1 million patients with melanoma in the United States are at risk to develop a second primary melanoma. Early detection of melanoma improves survival. Patients with melanoma may be able to self-manage care with their skin-check partners (“partners”) and alert the physician when a concerning lesion is identified, thus providing an important adjunct to yearly skin examinations by a physician. OBJECTIVE To evaluate the effect of a structured skin self-examination (SSE) intervention for patients with melanoma and their partners (“dyads”) on SSE performance and the detection of new melanomas by the dyad or the physician. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial with 24-month follow-up assessments. Patients with stage 0 to IIB melanoma and their skin-check partners participated from June 6, 2011, to April 24, 2015. INTERVENTIONS Dyads of patients and their partners were randomly assigned to receive the skills training intervention or customary care (control group). MAIN OUTCOMES AND MEASURES The main outcome was frequency of SSE performance. The secondary outcome was detection of a new or recurrent melanoma by the dyad or physician. The tertiary outcome was the number of unscheduled physician appointments for concerning lesions. RESULTS The study cohort comprised 494 participants. The patient population was 51.2% (253 of 494) female and had a mean (SD) age of 55 (10) years. Patients in the intervention arms had significantly increased SSEs with their partners at 4, 12, and 24 months (P < .001 for all) compared with the control group (mean differences, 1.57 [95% CI, 1.29–1.85], 0.72 [95% CI, 0.39–1.06], and 0.94 [95% CI, 0.58–1.30], respectively). Patients in the intervention arms identified new melanomas more than those in the control group ( χ12=28.77, P < .01 [n = 51 melanomas in situ] and χ12=6.43, P < .05 [n = 18 invasive melanomas]) and did not increase physician visits.

Minimally invasive liver resection to obtain tumor-infiltrating lymphocytes for adoptive cell therapy in patients with metastatic melanoma

PubMed Central

2012-01-01

Background Adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TIL) in patients with metastatic melanoma has been reported to have a 56% overall response rate with 20% complete responders. To increase the availability of this promising therapy in patients with advanced melanoma, a minimally invasive approach to procure tumor for TIL generation is warranted. Methods A feasibility study was performed to determine the safety and efficacy of laparoscopic liver resection to generate TIL for ACT. Retrospective review of a prospectively maintained database identified 22 patients with advanced melanoma and visceral metastasis (AJCC Stage M1c) who underwent laparoscopic liver resection between 1 October 2005 and 31 July 2011. The indication for resection in all patients was to receive postoperative ACT with TIL. Results Twenty patients (91%) underwent resection utilizing a closed laparoscopic technique, one required hand-assistance and another required conversion to open resection. Median intraoperative blood loss was 100 mL with most cases performed without a Pringle maneuver. Median hospital stay was 3 days. Three (14%) patients experienced a complication from resection with no mortality. TIL were generated from 18 of 22 (82%) patients. Twelve of 15 (80%) TIL tested were found to have in vitro tumor reactivity. Eleven patients (50%) received the intended ACT. Two patients were rendered no evidence of disease after surgical resection, with one undergoing delayed ACT with generated TIL after relapse. Objective tumor response was seen in 5 of 11 patients (45%) who received TIL, with one patient experiencing an ongoing complete response (32+ months). Conclusions Laparoscopic liver resection can be performed with minimal morbidity and serve as an effective means to procure tumor to generate therapeutic TIL for ACT to patients with metastatic melanoma.

To report a case of choroidal malignant melanoma in a patient with Waardenburg syndrome and bilateral choroidal pigmentary abnormalities. Clinical examination and multimodal imaging of the case. A 45-year-old woman presented with asymptomatic flat choroidal pigmentation abnormalities in both eyes. A choroidal lesion was identified in the inferotemporal periphery of the left eye arising from an area of hyperpigmentation; ultrasonography findings were consistent with a choroidal melanoma. The patient endorsed a personal and family history of premature graying of hair and was identified to have dystopia canthorum consistent with the diagnosis of Waardenburg syndrome. The authors present the first reported case of concurrent Waardenburg syndrome and choroidal malignant melanoma. This cooccurrence may suggest that the relative hyperpigmented regions in affected fundi may be abnormal and should be monitored closely for the development of choroidal melanoma.

Mucosal melanoma is a rare but aggressive subtype of melanoma with unique clinicopathologic features. We hypothesize that mucosal melanoma shows predilection for separate and unique metastatic pathways. This was a retrospective analysis of 19 patients (5 men and 14 women; median age 60 years, range 38-76 years) with metastatic mucosal melanoma presenting to a tertiary oncology center between 2005 and 2010. We performed a review of medical records and histologic and imaging studies to evaluate the natural history, metastatic patterns and the role of imaging in the management of patients with advanced mucosal melanoma. At presentation, disease was confined to the primary site (58%, n = 11) or to the regional lymph nodes (32%, n = 6) in most patients. The most common site of metastasis was the lungs (89%, n = 16), followed by the liver (67%, n = 12) and peritoneum (44%, n = 8). Sinonasal melanoma preferentially spread to the liver (100%, n = 4), vaginal melanoma to the lungs (100%, n = 7) and anal melanoma to the inguinal lymph nodes (100%, n = 4). Pathways of metastatic spread in mucosal melanoma may differ from other forms of melanoma and between different primary sites of mucosal origin.

The single-arm, phase II Tasigna Efficacy in Advanced Melanoma (TEAM) trial evaluated the KIT-selective tyrosine kinase inhibitor nilotinib in patients with KIT-mutated advanced melanoma without prior KIT inhibitor treatment. Forty-two patients with KIT-mutated advanced melanoma were enrolled and treated with nilotinib 400 mg twice daily. TEAM originally included a comparator arm of dacarbazine (DTIC)-treated patients; the design was amended to a single-arm trial due to an observed low number of KIT-mutated melanomas. Thirteen patients were randomized to DTIC before the protocol amendment removing this study arm. The primary endpoint was objective response rate (ORR), determined according to Response Evaluation Criteria In Solid Tumors. ORR was 26.2% (n = 11/42; 95% CI, 13.9%-42.0%), sufficient to reject the null hypothesis (ORR ≤10%). All observed responses were partial responses (PRs; median response duration, 7.1 months). Twenty patients (47.6%) had stable disease and 10 (23.8%) had progressive disease; 1 (2.4%) response was unknown. Ten of the 11 responding patients had exon 11 mutations, four with an L576P mutation. The median progression-free survival and overall survival were 4.2 and 18.0 months, respectively. Three of the 13 patients on DTIC achieved a PR, and another patient had a PR following switch to nilotinib. Nilotinib activity in patients with advanced KIT-mutated melanoma was similar to historical data from imatinib-treated patients. DTIC treatment showed potential activity, although the low patient number limits interpretation. Similar to previously reported results with imatinib, nilotinib showed greater activity among patients with an exon 11 mutation, including L576P, suggesting that nilotinib may be an effective treatment option for patients with specific KIT mutations.

Background Detection of melanoma cells in circulation may be important in assessing tumor progression. The objective of this study was to develop a specific, reliable, multimarker quantitative real-time reverse transcription-PCR (qRT) assay for detecting melanoma cells in patients’ blood. Methods We developed qRT assays for the mRNA of four melanoma-associated markers: MART-1, GalNAc-T, PAX-3, and MAGE-A3. In optimization studies, we tested 17 melanoma cell lines and 49 peripheral blood leukocyte (PBL) samples from volunteers. We performed RNA and melanoma cell dilution studies to assess the detection limits and imprecision of the assays. We measured the mRNAs in blood specimens from 94 melanoma patients [American Joint Committee on Cancer (AJCC) stage I, n = 20; II, n = 20; III, n = 32; IV, n = 22]. Results All markers were frequently detected in melanoma cell lines, whereas none of the markers was detected in PBLs from volunteers. The qRT assay could detect 1 melanoma cell in 107 PBLs in the melanoma cell-dilution studies. Markers were detected in 15%, 30%, 75%, and 86% of melanoma patients with AJCC stage I, II, III, and IV disease, respectively. The number of positive markers and AJCC stage were significantly correlated (Spearman correlation coefficient = 0.58; P <0.0001). Conclusions Multimarker qRT can detect circulating melanoma cells in blood. Measurement of the studied molecular markers in blood may be useful in detection of metastasis and monitoring treatment response of melanoma patients. PMID:15817820

The objectives of this study were to evaluate and model the probability of melanoma-specific death and competing causes of death for patients with melanoma by competing risk analysis, and to build competing risk nomograms to provide individualized and accurate predictive tools. Melanoma data were obtained from the Surveillance Epidemiology and End Results program. All patients diagnosed with primary non-metastatic melanoma during the years 2004-2007 were potentially eligible for inclusion. The cumulative incidence function (CIF) was used to describe the probability of melanoma mortality and competing risk mortality. We used Gray's test to compare differences in CIF between groups. The proportional subdistribution hazard approach by Fine and Gray was used to model CIF. We built competing risk nomograms based on the models that we developed. The 5-year cumulative incidence of melanoma death was 7.1 %, and the cumulative incidence of other causes of death was 7.4 %. We identified that variables associated with an elevated probability of melanoma-specific mortality included older age, male sex, thick melanoma, ulcerated cancer, and positive lymph nodes. The nomograms were well calibrated. C-indexes were 0.85 and 0.83 for nomograms predicting the probability of melanoma mortality and competing risk mortality, which suggests good discriminative ability. This large study cohort enabled us to build a reliable competing risk model and nomogram for predicting melanoma prognosis. Model performance proved to be good. This individualized predictive tool can be used in clinical practice to help treatment-related decision making.

Recent Advances in Hydrogel-Based Drug Delivery for Melanoma Cancer Therapy: A Mini Review

2017-01-01

The purpose of this study is to describe some of the latest advances in using hydrogels for cancer melanoma therapy. Hydrogel formulations of polymeric material from natural or synthetic sources combined with therapeutic agents have gained great attention in the recent years for treating various maladies. These formulations can be categorized according to the strategies that induce cancer cell death in melanoma. First of all, we should note that these formulations can only play a supporting role that releases bioactive agents against cancer cells rather than the main role. This strategy involves delivering the drug via transdermal pathways, resulting in the death of cancerous cells. Another strategy utilizes magnetic gel composites to combat melanoma via hyperthermia therapy. This review discusses both transdermal and hyperthermia therapies and the recent advances that have occurred in the field. PMID:28852576

Brain metastases cause significant morbidity and mortality in patients with metastatic melanoma. Although adoptive cell therapy (ACT) with tumor-infiltrating lymphocytes (TIL) can achieve complete and durable remission of advanced cutaneous melanoma, the efficacy of this therapy for brain metastases is unclear. Records of patients with M1c melanoma treated with ACT using TIL, including patients with treated and untreated brain metastases, were analyzed. Treatment consisted of preparative chemotherapy, autologous TIL infusion, and high-dose interleukin-2. Treatment outcomes, sites of initial tumor progression, and overall survival were analyzed. Among 144 total patients, 15 patients with treated and 18 patients with untreated brain metastases were identified. Intracranial objective responses (OR) occurred in 28% patients with untreated brain metastases. The systemic OR rates for patients with M1c disease without identified brain disease, treated brain disease, and untreated brain disease, and were 49%, 33% and 33%, respectively, of which 59%, 20% and 16% were durable at last follow-up. The site of untreated brain disease was the most likely site of initial tumor progression (61%) in patients with untreated brain metastases. Overall, we found that ACT with TIL can eliminate small melanoma brain metastases. However, following TIL therapy these patients frequently progress in the brain at a site of untreated brain disease. Patients with treated or untreated brain disease are less likely to achieve durable systemic ORs following TIL therapy compared with M1c disease and no history of brain disease. Melanoma brain metastases likely require local therapy despite the systemic effect of ACT.

In recent years, the treatment of metastatic melanoma has changed dramatically due to the development of immune checkpoint and mitogen-activated protein (MAP) kinase inhibitors. A population-based registry, the Dutch Melanoma Treatment Registry (DMTR), was set up in July 2013 to assure the safety and quality of melanoma care in the Netherlands. This article describes the design and objectives of the DMTR and presents some results of the first 2 years of registration. The DMTR documents detailed information on all Dutch patients with unresectable stage IIIc or IV melanoma. This includes tumour and patient characteristics, treatment patterns, clinical outcomes, quality of life, healthcare utilisation, informal care and productivity losses. These data are used for clinical auditing, increasing the transparency of melanoma care, providing insights into real-world cost-effectiveness and creating a platform for research. Within 1 year, all melanoma centres were participating in the DMTR. The quality performance indicators demonstrated that the BRAF inhibitors and ipilimumab have been safely introduced in the Netherlands with toxicity rates that were consistent with the phase III trials conducted. The median overall survival of patients treated with systemic therapy was 10.1 months (95% confidence interval [CI] 9.1-11.1) in the first registration year and 12.7 months (95% CI 11.6-13.7) in the second year. The DMTR is the first comprehensive multipurpose nationwide registry and its collaboration with all stakeholders involved in melanoma care reflects an integrative view of cancer management. In future, the DMTR will provide insights into challenging questions regarding the definition of possible subsets of patients who benefit most from the new drugs. Copyright © 2016 Elsevier Ltd.

As part of the 2017 Melanoma Bridge congress (November 30-December 2, 2017, Napoli, Italy), the great debate session featured counterpoint views from leading experts on three contemporary controversial clinical issues in the care of the melanoma patient. These were: (1) whether complete lymph node dissection should be routinely offered to all melanoma patients with sentinel lymph node-positive disease; (2) whether first-line treatment of BRAF-mutated melanoma should consist of BRAF-targeted therapy or immunotherapy with checkpoint inhibitors; and (3) whether combined or sequential administration of treatments should be the preferred option in the management of patients with advanced melanoma. Discussion of these three important issues and audience responses are reported here.

Context: Immune checkpoint blockade is associated with endocrine-related adverse events. Thyroid dysfunction during pembrolizumab therapy, an anti-programmed cell death 1 (PD-1) receptor monoclonal antibody, remains to be fully characterized. Objective: To assess the incidence and characteristics of pembrolizumab-associated thyroid dysfunction. Design and Setting: Thyroid function was monitored prospectively in melanoma patients who initiated pembrolizumab within an expanded access program at a referral oncology center. 18Fluorodeoxyglucose uptake on positron emission tomography/computed tomography (18FDG-PET/CT) was reviewed in cases compatible with inflammatory thyroiditis. Patients: Ninety-nine patients with advanced melanoma (age, 26.3–93.6 years; 63.6% females) who received at least one administration of pembrolizumab. Main Outcome Measures: Patient characteristics, thyroid function (TSH, free T4), thyroid autoantibodies, and 18FDG-PET/CT. Results: Eighteen adverse events of thyroid dysfunction were observed in 17 patients. Thyrotoxicosis occurred in 12 patients, of which nine evolved to hypothyroidism. Isolated hypothyroidism was present in six patients. Levothyroxine therapy was required in 10 of 15 hypothyroid patients. Thyroid autoantibodies were elevated during thyroid dysfunction in four of 10 cases. Diffuse increased 18FDG uptake by the thyroid gland was observed in all seven thyrotoxic patients who progressed to hypothyroidism. Conclusions: Thyroid dysfunction is common in melanoma patients treated with pembrolizumab. Hypothyroidism and thyrotoxicosis related to inflammatory thyroiditis are the most frequent presentations. Serial measurements of thyroid function tests are indicated during anti-PD-1 monoclonal antibody therapy. Thyrotoxicosis compatible with inflammatory thyroiditis was associated with diffuse increased 18FDG uptake by the thyroid gland. The prospective role of thyroid autoantibodies should be further investigated, together with the

Melanoma is a cancer of the neural crest–derived cells that provide pigmentation to skin and other tissues. Over the past 4 decades, the incidence of melanoma has increased more rapidly than that of any other malignancy in the United States. No current treatments substantially enhance patient survival once metastasis has occurred. This review focuses on recent insights into melanoma genetics and new therapeutic approaches being developed based on these advances. PMID:15841168

Melanoma is an increasingly common skin cancer worldwide. Recent treatment advances have provided patients and healthcare professionals (HCPs) with choices where quality of life (QoL) and toxicity are important considerations. A melanoma-specific QoL questionnaire is being developed in a cross-cultural setting using a four phase process developed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group. In phase 1, a literature search identified a list of pertinent QoL issues; this was shown to HCPs and patients in eight countries and rated for importance and relevance. Questions were constructed for the highest-rated issues (phase 2) and piloted in another patient sample (phase 3). Using EORTC Quality of Life Group criteria and sequential use of factor and Rasch analysis, scales were hypothesized for field testing (phase 4). Seven QoL domains (disease symptoms, treatment issues, financial issues, access/quality of information, satisfaction with care, psychosocial issues and support), comprising 73 QoL issues, were rated by 46 HCPs and 78 patients. Fifty-six issues were rephrased as questions and piloted with 132 patients. A 38-item questionnaire (QLQ-MEL38) is available for field testing in conjunction with the EORTC QLQ-C30. This study has shown that melanoma patients have important QoL issues that have been incorporated into a new cross-culturally validated instrument. Future testing of this EORTC module is planned and will be an important step forward in providing reliable QoL data to aid future decision-making in the management and clinical trials of this complex group of patients.

Both cutaneous and uveal melanoma undergo haematogenous dissemination. Detection of tyrosinase mRNA by reverse transcription-polymerase chain reaction (RT-PCR) has been described as an extremely sensitive way of detecting circulating viable melanoma cells in the peripheral venous blood, and this technique may be of value in the early detection of dissemination. Also, it has been suggested that surgical manipulation of the eye, such as occurs during enucleation, can provoke uveal melanoma dissemination. The purpose of this study was to evaluate whether tyrosinase mRNA is detectable in the peripheral blood of patients with uveal and cutaneous melanoma and in patients with uveal melanoma undergoing surgical procedures on the eye harbouring the tumour. Venous blood samples from 36 patients diagnosed as having active uveal melanoma and from six patients with advanced metastatic cutaneous melanoma were analysed. In addition, blood samples were spiked with known numbers of cells from three cell lines and four primary uveal melanoma cultures. The reported sensitivity of the technique was confirmed, with an ability to detect down to one cell per ml of blood. All 51 blood samples from the 36 patients with uveal melanoma were negative, and this included 20 perioperative blood samples. The test was also negative for the six patients with advanced cutaneous melanoma. There were two positives among 31 control samples analysed. This study demonstrates that there are far fewer circulating viable melanocytes than has been previously supposed in patients with melanoma and that the RT-PCR is of no clinical value in detecting metastatic melanoma disease. There was no evidence for surgery causing a bolus of melanoma cells to enter the peripheral circulation. Images Figure 1 Figure 2 PMID:7599046

Background: Inter-patient pharmacokinetic variability can lead to suboptimal drug exposure, and therefore might impact the efficacy of sorafenib. This study reports long-term pharmacokinetic monitoring of patients treated with sorafenib and a retrospective pharmacodynamic/pharmacokinetic analysis in melanoma patients. Patients and methods: Heavily pretreated patients with stage IV melanoma were started on sorafenib 400 mg twice daily (bid). In the absence of limiting toxicity, dose escalation of 200 mg bid levels was done every 2 weeks. Plasma sorafenib measurement was performed at each visit, allowing a retrospective pharmacodynamic/pharmacokinetic analysis for safety and efficacy. Results: In all, 19 of 30 patients underwent dose escalation over 400 mg bid, and 28 were evaluable for response. The overall disease control rate was 61% (95% confidence interval (CI): 42.6–78.8), including three confirmed responses (12%). Disease control rate and progression-free survival (PFS) were improved in patients with high vs low exposure (80% vs 32%, P=0.02, and 5.25 vs 2.5 months, P=0.005, hazard ratio (HR)=0.28 (95% CI: 0.11–0.73)). In contrast, drug dosing had no effect on PFS. In multivariate analysis, drug exposure was the only factor associated with PFS (HR=0.36 (95% CI: 0.13–0.99)). Diarrhoea and anorexia were correlated with drug dosing, while hypertension and hand–foot skin reaction were correlated with drug exposure. Conclusions: Although sorafenib had modest efficacy in melanoma, these results suggest a correlation between exposure and efficacy of sorafenib. Therefore, dose optimisation in patients with low exposure at standard doses should be evaluated in validated indications. PMID:22767146

Ocular melanoma is the second most common type of melanoma after cutaneous and the most common primary intraocular malignant tumor in adults. Large majority of ocular melanomas originate from uvea, while conjunctival melanomas are far less frequent. Incidence of uveal melanoma has remained stable over last three decades. Diagnosis is in most cases established by clinical examination with great accuracy. Local treatment of uveal melanoma has improved, with increased use of conservative methods and preservation of the eye, but survival rates have remained unchanged. Recent advances in cytogenetics and genetics enhanced prognostication and enabled to determine tumors with high metastatic potential. However, due to lack of effective systemic therapy, prognosis of patients with metastasis remains poor and metastatic disease remains the leading cause of death among patients with uveal melanoma. Conjunctival melanoma is rare, but its incidence is increasing. It mostly occurs among white adults. In majority of cases it originates from preceding primary acquired melanosis. Current standard treatment for conjunctival melanoma is wide local excision with adjuvant therapy, including brachytherapy, cryotherapy and topical application of chemotherapeutic agent. Rarity of this tumor limits conduction of controlled trials to define the best treatment modality. As well as for uveal melanoma, prognosis of patients with metastasis is poor because there is no effective systemic therapy. Better understanding of underlying genetic and molecular abnormalities implicated in development and progression of ocular melanomas provides a great opportunity for development of targeted therapy, which will hopefully improve prognosis of patients with metastatic disease.

Abstract Purpose: Mucosal melanoma is a rare but aggressive subtype of melanoma with unique clinicopathologic features. We hypothesize that mucosal melanoma shows predilection for separate and unique metastatic pathways. Materials and methods: This was a retrospective analysis of 19 patients (5 men and 14 women; median age 60 years, range 38–76 years) with metastatic mucosal melanoma presenting to a tertiary oncology center between 2005 and 2010. We performed a review of medical records and histologic and imaging studies to evaluate the natural history, metastatic patterns and the role of imaging in the management of patients with advanced mucosal melanoma. Results: At presentation, disease was confined to the primary site (58%, n = 11) or to the regional lymph nodes (32%, n = 6) in most patients. The most common site of metastasis was the lungs (89%, n = 16), followed by the liver (67%, n = 12) and peritoneum (44%, n = 8). Sinonasal melanoma preferentially spread to the liver (100%, n = 4), vaginal melanoma to the lungs (100%, n = 7) and anal melanoma to the inguinal lymph nodes (100%, n = 4). Conclusion: Pathways of metastatic spread in mucosal melanoma may differ from other forms of melanoma and between different primary sites of mucosal origin. PMID:24434078

We report a new immunological treatment for advanced cutaneous melanoma which combines laser stimulation with topical application of a toll-like receptor agonist. This treatment, in situ photoimmunotherapy (ISPI), provides an alternative to traditional therapies for melanoma patients with cutaneous metastases. A 6-week cycle of ISPI is carried out on cutaneous metastases located in a designated 20 x 20 cm treatment area: 2 weeks of pretreatment with twice-daily topical applications of imiquimod (5% cream under plastic occlusion), with a laser treatment session at week 2 and again at week 4. Topical imiquimod is continued for the entire 6-week cycle. Two patients with late-stage melanoma were treated with ISPI. Patient 1 had the primary tumour and local metastases on the left arm, as well as metastatic tumours in the lungs [American Joint Committee on Cancer (AJCC) stage IV]. Patient 2 had a head and neck melanoma with multiple local metastases (AJCC stage IIIC), which had failed repeated attempts at surgical resection and high-dose radiation therapy. Patient 1 is now free of all clinically detectable tumours (including the lung metastases) >20 months after the first treatment cycle. Patient 2 has been free of any clinical evidence of the tumour for over 6 months. These two cases demonstrate that ISPI can clear local tumour and trigger beneficial systemic responses, with a side-effect profile that compares favourably with other treatments for advanced melanoma.

Communication about melanoma and risk reduction after melanoma diagnosis.

Melanoma patients are advised to perform regular risk-reduction practices, including sun protection as well as skin self-examinations (SSEs) and physician-led examinations. Melanoma-specific communication regarding family risk and screening may promote such behaviors. To this end, associations between patients' melanoma-specific communication and risk reduction were examined. Melanoma patients (N = 169) drawn from a population-based cancer registry reported their current risk-reduction practices, perceived risk of future melanoma, and communication with physicians and relatives about melanoma risk and screening. Patients were, on average, 56 years old and 6.7 years' post diagnosis; 51% were male, 93% reported "fair/very fair" skin color, 75% completed at least some college, and 22% reported a family history of melanoma. Patients reported varying levels of regular (always/nearly always) sun protection: sunscreen use (79%), shade seeking (60%), hat use (54%), and long-sleeve shirt use (30%). Only 28% performed thorough SSE regularly, whereas 92% reported undergoing physician-led skin examinations within the past year. Participants who were female, younger, and had a higher perceived risk of future melanoma were more likely to report past communication. In adjusted analyses, communication remained uniquely associated with increased sunscreen use and SSE. Encouraging melanoma patients to have a more active role in discussions concerning melanoma risk and screening with relatives and physicians alike may be a useful strategy to promote 2 key risk-reduction practices post melanoma diagnosis and treatment. Future research is needed to identify additional strategies to improve comprehensive risk reduction in long-term melanoma patients. Copyright © 2016 John Wiley & Sons, Ltd.

Purpose: Pembrolizumab monotherapy, ipilimumab monotherapy, and pegylated interferon alfa-2b (PEG-IFN) monotherapy are active against melanoma and renal cell carcinoma (RCC). We explored the safety and preliminary antitumor activity of pembrolizumab combined with either ipilimumab or PEG-IFN in patients with advanced melanoma or RCC. Experimental Design: The phase Ib KEYNOTE-029 study (ClinicalTrials.gov, NCT02089685) included independent pembrolizumab plus reduced-dose ipilimumab and pembrolizumab plus PEG-IFN cohorts. Pembrolizumab 2 mg/kg every 3 weeks (Q3W) plus 4 doses of ipilimumab 1 mg/kg Q3W was tolerable if ≤6 of 18 patients experienced a dose-limiting toxicity (DLT). The target DLT rate for pembrolizumab 2 mg/kg Q3W plus PEG-IFN was 30%, with a maximum of 14 patients per dose level. Response was assessed per RECIST v1.1 by central review. Results: The ipilimumab cohort enrolled 22 patients, including 19 evaluable for DLTs. Six patients experienced ≥1 DLT. Grade 3 to 4 treatment-related adverse events occurred in 13 (59%) patients. Responses occurred in 5 of 12 (42%) patients with melanoma and 3 of 10 (30%) patients with RCC. In the PEG-IFN cohort, DLTs occurred in 2 of 14 (14%) patients treated at dose level 1 (PEG-IFN 1 μg/kg/week) and 2 of 3 (67%) patients treated at dose level 2 (PEG-IFN 2 μg/kg/week). Grade 3 to 4 treatment-related adverse events occurred in 10 of 17 (59%) patients. Responses occurred in 1 of 5 (20%) patients with melanoma and 2 of 12 (17%) patients with RCC. Conclusions: Pembrolizumab 2 mg/kg Q3W plus ipilimumab 1 mg/kg Q3W was tolerable and provided promising antitumor activity in patients with advanced melanoma or RCC. The maximum tolerated dose of pembrolizumab plus PEG-IFN had limited antitumor activity in this population.

Immune checkpoint blockers (ICB) have become pivotal therapies in the clinical armamentarium against metastatic melanoma (MMel). Given the frequency of immune related adverse events and increasing use of ICB, predictors of response to CTLA-4 and/or PD-1 blockade represent unmet clinical needs. Using a systems biology-based approach to an assessment of 779 paired blood and tumor markers in 37 stage III MMel patients, we analyzed association between blood immune parameters and the functional immune reactivity of tumor-infiltrating cells after ex vivo exposure to ICB. Based on this assay, we retrospectively observed, in eight cohorts enrolling 190 MMel patients treated with ipilimumab, that PD-L1 expression on peripheral T cells was prognostic on overall and progression-free survival. Moreover, detectable CD137 on circulating CD8 + T cells was associated with the disease-free status of resected stage III MMel patients after adjuvant ipilimumab + nivolumab (but not nivolumab alone). These biomarkers should be validated in prospective trials in MMel.The clinical management of metastatic melanoma requires predictors of the response to checkpoint blockade. Here, the authors use immunological assays to identify potential prognostic/predictive biomarkers in circulating blood cells and in tumor-infiltrating lymphocytes from patients with resected stage III melanoma.

NRAS and BRAF mutations in melanoma inform current treatment paradigms, but their role in survival from primary melanoma has not been established. Identification of patients at high risk of melanoma-related death based on their primary melanoma characteristics before evidence of recurrence could inform recommendations for patient follow-up and eligibility for adjuvant trials. To determine tumor characteristics and survival from primary melanoma by somatic NRAS and BRAF status. A population-based study with a median follow-up of 7.6 years (through 2007), including 912 patients from the United States and Australia in the Genes, Environment, and Melanoma (GEM) Study, with first primary cutaneous melanoma diagnosed in the year 2000 and analyzed for NRAS and BRAF mutations. Tumor characteristics and melanoma-specific survival of primary melanoma by NRAS and BRAF mutational status. The melanomas were 13% NRAS+, 30% BRAF+, and 57% with neither NRAS nor BRAF mutation (wildtype [WT]). In a multivariable model including clinicopathologic characteristics, relative to WT melanoma (with results reported as odds ratios [95% CIs]), NRAS+ melanoma was associated with presence of mitoses (1.8 [1.0-3.3]), lower tumor-infiltrating lymphocyte (TIL) grade (nonbrisk, 0.5 [0.3-0.8]; and brisk, 0.3 [0.5-0.7] [vs absent TILs]), and anatomic site other than scalp/neck (0.1 [0.01-0.6] for scalp/neck vs trunk/pelvis), and BRAF+ melanoma was associated with younger age (ages 50-69 years, 0.7 [0.5-1.0]; and ages >70 years, 0.5 [0.3-0.8] [vs <50 years]), superficial spreading subtype (nodular, 0.5 [0.2-1.0]; lentigo maligna, 0.4 [0.2-0.7]; and unclassified/other, 0.2 [0.1-0.5] [vs superficial spreading]), and presence of mitoses (1.7 [1.1-2.6]) (P < .05 for all). There was no significant difference in melanoma-specific survival (reported as hazard ratios [95% CIs]) for melanoma harboring mutations in NRAS (1.7 [0.8-3.4]) or BRAF (1.5 [0.8-2.9]) compared with WT melanoma, as adjusted for age

Studies of human cancer metastasis have been limited by a lack of experimental assays in which cancer cells from patients metastasize in vivo in a way that correlates with clinical outcome. This makes it impossible to study intrinsic differences in the metastatic properties of cancers from different patients. We recently developed an assay in which human melanomas readily engraft in NOD/SCID IL2Rγnull (NSG) mice (1, 2). Here we show that melanomas from 25 patients exhibited reproducible differences in the rate of spontaneous metastasis after transplantation into NSG mice and that these differences correlated with clinical outcome in the patients. Stage IIIB/C melanomas that formed distant metastases within 22 months in patients also formed tumors that metastasized widely in NSG mice, while stage IIIB/C melanomas that did not form distant metastases within 22–50 months in patients metastasized more slowly in NSG mice. These differences in the efficiency of metastasis correlated with the frequency of circulating melanoma cells in the blood of NSG mice, suggesting that the rate of entry into the blood is one factor that limits the rate of metastasis. NSG mice can therefore be used to study the metastasis of human melanomas in vivo, revealing intrinsic differences among stage III melanomas in their ability to circulate/survive in the blood and metastasize.

Despite recent advances, the treatment of malignant melanoma still results in the relapse of the disease, and second line treatment mostly fails due to the occurrence of resistance. A wide range of mutations are known to prevent effective treatment with chemotherapeutic drugs. Hence, approaches with biopharmaceuticals including proteins, like antibodies or cytokines, are applied. As an alternative, regimens with therapeutically active nucleic acids offer the possibility for highly selective cancer treatment whilst avoiding unwanted and toxic side effects. This paper gives a brief introduction into the mechanism of this devastating disease, discusses the shortcoming of current therapy approaches, and pinpoints anchor points which could be harnessed for therapeutic intervention with nucleic acids. We bring the delivery of nucleic acid nanopharmaceutics into perspective as a novel antimelanoma therapeutic approach and discuss the possibilities for melanoma specific targeting. The latest reports on preclinical and already clinical application of nucleic acids in melanoma are discussed. PMID:23634303

Purpose: To evaluate the applicability of carbon ion beams for the treatment of choroidal melanoma with regard to normal tissue morbidity and local tumor control. Methods and Materials: Between January 2001 and February 2006, 59 patients with locally advanced or unfavorably located choroidal melanoma were enrolled in a Phase I/II clinical trial of carbon-ion radiotherapy at the National Institute of Radiologic Sciences. The primary endpoint of this study was normal tissue morbidity, and secondary endpoints were local tumor control and patient survival. Of the 59 subjects enrolled, 57 were followed >6 months and analyzed. Results: Twenty-three patients (40%) developed neovascularmore » glaucoma, and three underwent enucleation for eye pain due to elevated intraocular pressure. Incidence of neovascular glaucoma was dependent on tumor size and site. Five patients had died at analysis, three of distant metastasis and two of concurrent disease. All but one patient, who developed marginal recurrence, were controlled locally. Six patients developed distant metastasis, five in the liver and one in the lung. Three-year overall survival, disease-free survival, and local control rates were 88.2%, 84.8%, and 97.4%, respectively. No apparent dose-response relationship was observed in either tumor control or normal tissue morbidity at the dose range applied. Conclusion: Carbon-ion radiotherapy can be applied to choroidal melanoma with an acceptable morbidity and sufficient antitumor effect, even with tumors of unfavorable size or site.« less

Metastasis represents the end product of an elaborate biological process, which is determined by a complex interplay between metastatic tumour cells, host factors and homoeostatic mechanisms. Cutaneous melanoma can metastasize haematogenously or lymphogenously. The three predominant models that endeavour to explain the patterns of melanoma progression are the stepwise spread model, the simultaneous spread model and the model of differential spread. The time course to the development of metastases differs between the different metastatic routes. There are several clinical and histopathological risk factors for the different metastatic pathways. In particular, patient sex and the anatomical location of the primary tumour influence patterns of disease progression. There is limited existing evidence regarding the relationship between tumour mutation status, other diagnostic and prognostic biomarkers and the metastatic pathways of primary cutaneous melanoma. This knowledge gap needs to be addressed to better identify patients at high risk of disease recurrence and personalize surveillance strategies. © 2016 John Wiley & Sons A/S.

The disease course of BRAF (v-raf murine sarcoma viral oncogene homolog B1)-mutant melanoma has been drastically improved by the arrival of targeted therapies. NRAS (neuroblastoma RAS viral oncogene homolog)-mutated melanoma represents 15–25% of all metastatic melanoma patients. It currently does not have an approved targeted therapy. Metastatic patients receive immune-based therapies as first-line treatments, then cytotoxic chemotherapy like carboplatin/paclitaxel (C/P), dacarbazine (DTIC) or temozolomide (TMZ) as a second-line treatment. We will review current preclinical and clinical developments in NRAS-mutated melanoma, and analyze ongoing clinical trials that are evaluating the benefit of different targeted and immune-based therapies, either tested as single agents or in combination, in NRAS-mutant melanoma.

Subcutaneous lesions may be detected during follow-up of patients with melanoma. The main entities that should be contemplated in the differential diagnosis in such cases are in-transit and regional lymph node metastases. We describe 2 cases of women with breast implants who developed palpable subcutaneous lesions in the axillary region during follow-up of melanoma. In both cases, the ultrasound study showed diffuse hyperechoic signals forming the characteristic snowstorm sign in the subcutaneous tissue. Ultrasound proved to be a key diagnostic tool for ruling out melanoma-related disease, such as in-transit metastases and regional lymph node metastases.

There is a growing body of evidence supporting the synergistic roles of radiotherapy and immunotherapy in the treatment of malignancy. Published case studies of the abscopal effect have been reported with the use of ipilimumab and radiotherapy in metastatic melanoma, but evidence supporting the routine use of this combination of therapy is limited. We conducted a retrospective analysis to evaluate patients treated with ipilimumab for advanced melanoma at a single institution from May 2011 to June 2015. Patients were grouped into those who had received concurrent radiotherapy while on ipilimumab (Ipi-RT), and those who did not. We then evaluated the treatment response following completion of ipilimumab. A total of 101 patients received ipilimumab in the prespecified time frame. 70 received Ipi-RT and 31 received ipilimumab without concurrent radiotherapy. Median overall survival (OS) was significantly increased in the concurrent Ipi-RT arm at 19 months vs. 10 months for ipilimumab alone (p = 0.01). Median progression free survival (PFS) was marginally increased in the Ipi-RT group compare with the ipilimumab alone group (5 months vs. 3 months, p = 0.20). Rates of complete response (CR) were significantly increased in the Ipi-RT group vs. ipilimumab alone (25.7% vs. 6.5%; p = 0.04), and rates of overall response (OR) in the groups were 37.1% vs. 19.4% (p = 0.11). No increase in toxicities was observed in the Ipi-RT group compare with ipilimumab alone. Prospective trials are needed to further clarify the role of radiotherapy with ipilimumab, but these encouraging preliminary observations suggest that this combination can induce more durable responses to immunotherapy.

Melanin possess radioprotective and scavenging properties, and its presence can affect the behavior of melanoma cells, its surrounding environment and susceptibility to the therapy, as showed in vitro experiments. To determine whether melanin presence in melanoma affects the efficiency of radiotherapy (RTH) we evaluated the survival time after RTH treatment in metastatic melanoma patients (n = 57). In another cohort of melanoma patients (n = 84), the relationship between melanin level and pT and pN status was determined. A significantly longer survival time was found in patients with amelanotic metastatic melanomas in comparison to the melanotic ones, who were treated with either RTH or chemotherapy (CHTH) and RTH. These differences were more significant in a group of melanoma patients treated only with RTH. A detailed analysis of primary melanomas revealed that melanin levels were significantly higher in melanoma cells invading reticular dermis than the papillary dermis. A significant reduction of melanin pigmentation in pT3 and pT4 melanomas in comparison to pT1 and T2 tumors was observed. However, melanin levels measured in pT3-pT4 melanomas developing metastases (pN1-3, pM1) were higher than in pN0 and pM0 cases. The presence of melanin in metastatic melanoma cells decreases the outcome of radiotherapy, and melanin synthesis is related to higher disease advancement. Based on our previous cell-based and clinical research and present research we also suggest that inhibition of melanogenesis can improve radiotherapy modalities. The mechanism of relationship between melanogenesis and efficacy of RTH requires additional studies, including larger melanoma patients population and orthotopic, imageable mouse models of metastatic melanoma.

The utility of ultrasound in patients with melanoma.

The highest quality gray-scale ultrasound images are obtained with high-frequency transducers; however, such high frequencies do not penetrate more than a few centimeters into body tissue. Fortunately, in patients with melanoma, the structures of interest are close to the skin surface, making them ideal targets for examination with high-resolution ultrasound. These include primary cutaneous melanomas, uveal melanomas and the regional lymph nodes draining the skin that lie in the axilla, groin, neck and other locations. Although ultrasound study of primary melanomas arising in the skin and eye has provided some insights, a major role for ultrasound has evolved recently, to provide early detection of metastatic melanoma in regional lymph nodes. Ultrasound is clearly superior to clinical palpation of the nodes during follow-up and, when combined with guided fine-needle biopsy, allows the earliest possible surgical intervention for regional nodal metastases. In the future the use of ultrasound contrast agents may improve the sensitivity of ultrasound in the detection of very small metastatic deposits.

In situ photoimmunotherapy for melanoma: an ongoing phase I clinical trial

In situ Photoimmunotherapy (ISPI) was developed to treat metastatic tumors using a combination of phototherapy and immunotherapy. It utilizes local intervention through photothermal destruction of existing solid tumors and through immune response modifier to elicit host anti-tumor responses. Such combination in pre-clinical studies has shown promise in cancer treatment by eradicating the primary tumors and also controlling metastases at distant sites. ISPI has been used in our preliminary clinical studies for melanoma patients and the outcome has been extremely encouraging. In 2006, we began enrolling patients in a new phase I immunotherapy trial for advanced cutaneous melanoma. This trial is based on our previous results which indicated that we had developed an effective treatment for advanced melanoma. Of the first six patients treated, (4 stage IV, and 2 surgically unresectable stage III), 2 of the stage IV patients are still alive, one tumor free, and one with a possible treatable recurrence after 2 1/2 years. We have also discovered that recurrences of the skin cancer can be retreated by the same technique and that treatment seems to blunt the virulence of the disease and make it more treatable. These initial results indicate that ISPI probably will have the ability to prolong survival in selected cases of advanced melanoma, and potentially cure a significant percentage of treated patients.

Vitamin D status and risk for malignant cutaneous melanoma: recent advances

Cutaneous malignant melanoma, whose incidence is increasing steadily worldwide, is the result of complex interactions between individual genetic factors and environmental risk factors. Ultraviolet radiation represents the most important environmental risk factor for the development of skin cancers, including melanoma. Sun exposure and early sunburn during childhood are the principal causes of cutaneous melanoma insurgence in adults, with double the risk relative to a nonexposed population. Consequently, ultraviolet protection has long been recognized as an important measure to prevent such a malignancy. Biological and epidemiological data suggest that vitamin D status could affect the risk of cancer and play a role in cancer prevention by exerting antiproliferative effects. Solar radiations are critical for vitamin D synthesis in humans; however, uncontrolled and intensive sun exposure is dangerous to skin health and may contribute toward the development of cutaneous malignant melanoma. An optimum balance between sun protection and exposure is thus advocated. Additional research is required to confirm the preventive role of vitamin D in melanoma incidence or a positive influence on patient outcome. PMID:28125434

Incidence of malignant melanoma is increasing globally. While the initial stages of tumors can be easily treated by a simple surgery, the therapy of advanced stages is rather limited. Melanoma cells spread rapidly through the body of a patient to form multiple metastases. Consequently, the survival rate is poor. Therefore, emphasis in melanoma research is given on early diagnosis and development of novel and more potent therapeutic options. The malignant melanoma is arising from melanocytes, cells protecting mitotically active keratinocytes against damage caused by UV light irradiation. The melanocytes originate in the neural crest and consequently migrate to the epidermis. The relationship between the melanoma cells, the melanocytes, and neural crest stem cells manifests when the melanoma cells are implanted to an early embryo: they use similar migratory routes as the normal neural crest cells. Moreover, malignant potential of these melanoma cells is overdriven in this experimental model, probably due to microenvironmental reprogramming. This observation demonstrates the crucial role of the microenvironment in melanoma biology. Indeed, malignant tumors in general represent complex ecosystems, where multiple cell types influence the growth of genetically mutated cancer cells. This concept is directly applicable to the malignant melanoma. Our review article focuses on possible strategies to modify the intercellular crosstalk in melanoma that can be employed for therapeutic purposes.

Sentinel lymph node biopsy (SLNB) is recommended for patients with intermediate-thickness melanoma, but the use of SLNB for patients with thick melanoma is debated. This report presents a single-institution study investigating factors predictive of sentinel lymph node (SLN) metastasis and outcome for thick-melanoma patients . A retrospective review of a single-institution database from 1997 to 2012 identified 147 patients with thick primary cutaneous melanoma (≥4 mm) who had an SLNB. Clinicopathologic characteristics were correlated with nodal status and outcome. The median age of the patients was 67 years, and 61.9 % of the patients were men. The median tumor thickness was 5.5 mm, and 54 patients (36.7 %) had a positive SLN. Multivariable analysis showed that only tumor thickness significantly predicted SLN metastasis (odds ratio 1.14; 95 % confidence interval (CI) 1.02-1.28; P = 0.02). The overall median follow-up period was 34.6 months. Overall survival (OS) and melanoma-specific survival (MSS) were significantly worse for the positive versus negative-SLN patients. Multivariable analysis showed that age [hazard ratio (HR) 1.04; 95 % CI 1.01-1.07; P = 0.02] and SLN status (HR 2.24; 95 % CI 1.03-4.88; P = 0.04) significantly predicted OS, whereas only SLN status (HR 3.85; 95 % CI 2.13-6.97; P < 0.01) significantly predicted MSS. Tumor thickness predicts SLN status in thick melanomas. Furthermore, SLN status is prognostic for OS and MSS in thick-melanoma patients, with positive-SLN patients having significantly worse OS and MSS. These findings show that SLNB should be recommended for thick-melanoma patients, particularly because detection of SLN metastasis can identify patients for potential systemic therapy and treatment of nodal disease at a microscopic stage.

Purpose Pembrolizumab provides durable antitumor activity in metastatic melanoma, including complete response (CR) in about 15% of patients. Data are limited on potential predictors of CR and patient disposition after pembrolizumab discontinuation after CR. We describe baseline characteristics and long-term follow-up in patients who experienced CR with pembrolizumab in the KEYNOTE-001 study ( ClinicalTrials.gov identifier: NCT01295827). Patients and Methods Patients with ipilimumab-naive or -treated advanced/metastatic melanoma received one of three dose regimens of pembrolizumab. Eligible patients who received pembrolizumab for ≥ 6 months and at least two treatments beyond confirmed CR could discontinue therapy. Response was assessed every 12 weeks by central Response Evaluation Criteria in Solid Tumors version 1.1. For this analysis, CR was defined per investigator assessment, immune-related response criteria, and potential predictors of CR were evaluated using univariate and multivariate analyses. Results Of 655 treated patients, 105 (16.0%) achieved CR after median follow-up of 43 months. At data cutoff, 92 patients (87.6%) had CR, with median follow-up of 30 months from first CR. Fourteen (13.3%) patients continued to receive treatment for a median of ≥ 40 months. Pembrolizumab was discontinued by 91 patients (86.7%), including 67 (63.8%) who proceeded to observation without additional anticancer therapy. The 24-month disease-free survival rate from time of CR was 90.9% in all 105 patients with CR and 89.9% in the 67 patients who discontinued pembrolizumab after CR for observation. Tumor size and programmed death-ligand 1 status were among the baseline factors independently associated with CR by univariate analysis. Conclusion Patients with metastatic melanoma can have durable complete remission after discontinuation of pembrolizumab, and the low incidence of relapse after median follow-up of approximately 2 years from discontinuation provides hope for a

Increased use of PET/CT scans in oncology patients has raised detection of Colorectal incidentalomas (CIs). The frequency and diagnostic outcomes of identifying these lesions in melanoma patients have not previously been studied. This studies primary objective was to determine the prevalence of CIs found on PET/CT scans in melanoma patients. The secondary objectives were to correlate the PET/CT findings with the pathology found at colonoscopy, and identify which patients were referred for colonoscopy. A retrospective analysis of patients identified from the prospectively collected research database of Melanoma Institute Australia. 2509 patients with melanoma underwent PET/CT scans between 2001 and 2013. The prevalence of CIs, the correlation of lesions, and the survival of patients who underwent colonoscopy versus patients who did not were analyzed. The prevalence of CIs in melanoma patients who had PET/CT scans was 3.2%. Forty-five of the 81 (56%) patients with CIs underwent colonoscopy. Of these, premalignant or malignant disease was found in 58%. Patients with previous metastatic melanoma were significantly less likely to be referred for colonoscopy. Patients undergoing colonoscopy had significantly better survival, as did those without previous distant metastases before the CIs were found, and those without any metastases at the time the CIs were found. These factors were not significant on multivariate analysis. The prevalence of incidental colorectal lesions identified on PET/CT scans in melanoma patients was found to be equivalent to that in the general cancer population. Patients undergoing colonoscopy had better survival than those who did not. Copyright © 2017 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

The prevalence of BRAF, NRAS, and p16CDKN2A mutations during melanoma progression remains inconclusive. We investigated the prevalence and distribution of mutations in these genes in different melanoma tissues. In all, 291 tumor tissues from 132 patients with melanoma were screened. Paired samples of primary melanomas (n = 102) and synchronous or asynchronous metastases from the same patients (n = 165) were included. Tissue samples underwent mutation analysis (automated DNA sequencing). Secondary lesions included lymph nodes (n = 84), and skin (n = 36), visceral (n = 25), and brain (n = 44) sites. BRAF/NRAS mutations were identified in 58% of primary melanomas (43% BRAF; 15% NRAS); 62% in lymph nodes, 61% subcutaneous, 56% visceral, and 70% in brain sites. Mutations were observed in 63% of metastases (48% BRAF; 15% NRAS), a nonsignificant increase in mutation frequency after progression from primary melanoma. Of the paired samples, lymph nodes (93% consistency) and visceral metastases (96% consistency) presented a highly similar distribution of BRAF/NRAS mutations versus primary melanomas, with a significantly less consistent pattern in brain (80%) and skin metastases (75%). This suggests that independent subclones are generated in some patients. p16CDKN2A mutations were identified in 7% and 14% of primary melanomas and metastases, with a low consistency (31%) between secondary and primary tumor samples. In the era of targeted therapies, assessment of the spectrum and distribution of alterations in molecular targets among patients with melanoma is needed. Our findings about the prevalence of BRAF/NRAS/p16CDKN2A mutations in paired tumor lesions from patients with melanoma may be useful in the management of this disease.

A high molecular weight-melanoma associated antigen-specific chimeric antigen receptor redirects lymphocytes to target human melanomas

Immunotherapy, particularly the adoptive cell transfer (ACT) of tumor infiltrating lymphocytes (TIL), is a very promising therapy for metastatic melanoma. Some patients unable to receive TIL have been successfully treated with autologous peripheral blood lymphocytes (PBL), genetically modified to express HLA class I antigen restricted, melanoma antigen-reactive T-cell receptors; however, substantial numbers of patients remain ineligible due to the lack of expression of the restricting HLA class I allele. We sought to overcome this limitation by designing a non-MHC-restricted, chimeric antigen receptor (CAR) targeting the high molecular weight-melanoma associated antigen (HMW-MAA), which is highly expressed on over 90% of human melanomas but has a restricted distribution in normal tissues. HMW-MAA-specific CARs containing an antigen recognition domain based on variations of the HMW-MAA-specific monoclonal antibody (mAb) 225.28S and a T-cell activation domain based on combinations of CD28, 4-1BB, and CD3ζ activation motifs were constructed within a retroviral vector to allow stable gene transfer into cells and their progeny. Following optimization of the HMW-MAA-specific CAR for expression and function in human PBL, these gene-modified T cells secreted cytokines, were cytolytic, and proliferated in response to HMW-MAA expressing cell lines. Furthermore, the receptor functioned in both CD4+ and CD8+ cells, was non-MHC-restricted, and reacted against explanted human melanomas. To evaluate this HMW-MAA-specific CAR in patients with metastatic melanoma, we developed a clinical-grade retroviral packaging line. This may represent a novel means to treat the majority of patients with advanced melanoma, most notably those unable to receive current ACT therapies. PMID:20395199

An estimated 73870 people will be diagnosed with melanoma in the United States in 2015, resulting in 9940 deaths. The majority of patients with cutaneous melanomas are cured with wide local excision. However, current evidence supports the use of sentinel lymph node biopsy (SLNB) given the 15%-20% of patients who harbor regional node metastasis. More importantly, the presence or absence of nodal micrometastases has been found to be the most important prognostic factor in early-stage melanoma, particularly in intermediate thickness melanoma. This review examines the development of SLNB for melanoma as a means to determine a patient’s nodal status, the efficacy of SLNB in patients with melanoma, and the biology of melanoma metastatic to sentinel lymph nodes. Prospective randomized trials have guided the development of practice guidelines for use of SLNB for melanoma and have shown the prognostic value of SLNB. Given the rapidly advancing molecular and surgical technologies, the technical aspects of diagnosis, identification, and management of regional lymph nodes in melanoma continues to evolve and to improve. Additionally, there is ongoing research examining both the role of SLNB for specific clinical scenarios and the ways to identify patients who may benefit from completion lymphadenectomy for a positive SLN. Until further data provides sufficient evidence to alter national consensus-based guidelines, SLNB with completion lymphadenectomy remains the standard of care for clinically node-negative patients found to have a positive SLN.

Background: This phase I–II trial compared plitidepsin 1-h infusion alone or combined with dacarbazine (DTIC) 1-h infusion as front-line therapy for advanced melanoma. Methods: The recommended dose (RD) for plitidepsin/DTIC was defined in the first stage. In the second stage, patients were randomised to receive single-agent plitidepsin 3.2 mg m−2 (n=20) on days 1, 8 and 15 every 4 weeks (q4wk) or plitidepsin 2.4 mg m−2 on days 1, 8 and 15 q4wk combined with DTIC 800 mg m−2 q4wk (n=38). Results: The overall response rate with plitidepsin/DTIC was 21.4% all responders had normal serum lactate dehydrogenase (LDH) levels and performance status ⩽1 at baseline. Median progression-free survival (PFS) with plitidepsin/DTIC was 3.3 months in all patients, and 4.3 months in those with baseline normal LDH. No responses occurred with single-agent plitidepsin and median PFS was 1.5 months. Both regimens were well tolerated. Haematological abnormalities were more common and transaminase increases more severe with plitidepsin/DTIC. Treatment-related transaminase increases leading to infusion omission on day 8 were relatively common. No drug–drug pharmacokinetic interactions were found. Conclusion: This plitidepsin/DTIC schedule has antitumour activity and manageable toxicity in advanced melanoma. Further evaluation of plitidepsin 2.4 mg m−2 fortnightly and DTIC 800 mg m−2 q4wk is recommended. PMID:23989947

Saiyed, Faiez K; Hamilton, Emma C; Austin, Mary T

2017-01-01

The purpose of this review is to outline recent advancements in diagnosis, treatment, and prevention of pediatric melanoma. Despite the recent decline in incidence, it continues to be the deadliest form of skin cancer in children and adolescents. Pediatric melanoma presents differently from adult melanoma; thus, the traditional asymmetry, border irregularity, color variegation, diameter >6 mm, and evolution (ABCDE) criteria have been modified to include features unique to pediatric melanoma (amelanotic, bleeding/bump, color uniformity, de novo/any diameter, evolution of mole). Surgical and medical management of pediatric melanoma continues to derive guidelines from adult melanoma treatment. However, more drug trials are being conducted to determine the specific impact of drug combinations on pediatric patients. Alongside medical and surgical treatment, prevention is a central component of battling the incidence, as ultraviolet (UV)-related mutations play a central role in the vast majority of pediatric melanoma cases. Aggressive prevention measures targeting sun safety and tanning bed usage have shown positive sun-safety behavior trends, as well as the potential to decrease melanomas that manifest later in life. As research into the field of pediatric melanoma continues to expand, a prevention paradigm needs to continue on a community-wide level. PMID:29388632

Progress in the management of patients with uveal melanoma. The 2012 Ashton Lecture

Damato, B

Uveal melanomas are diverse in their clinical features and behaviour. More than 90% involve the choroid, the remainder being confined to the ciliary body and iris. Most patients experience visual loss and more than a third require enucleation, in some cases because of pain. Diagnosis is based on slit-lamp biomicroscopy and/or ophthalmoscopy, with ultrasonography, autofluorescence photography, and/or biopsy in selected cases. Conservation of the eye with useful vision has improved with advances in brachytherapy, proton beam radiotherapy, endoresection, exoresection, transpupillary thermotherapy, and photodynamic therapy. Despite ocular treatment, almost 50% of patients develop metastatic disease, which occurs almost exclusively in patients whose tumour shows chromosome 3 loss and/or class 2 gene expression profile. When the tumour shows such lethal genetic changes, the survival time depends on the anatomical stage and the histological grade of malignancy. Prognostication has improved as a result of progress in multivariate analysis including all the major risk factors. Screening for metastases is more sensitive as a consequence of advances in liver scanning with magnetic resonance imaging and other methods. More patients with metastases are living longer, benefiting from therapies such as: partial hepatectomy; radiofrequency ablation; ipilumumab immunotherapy; selective internal radiotherapy; intra-hepatic chemotherapy, possibly with isolated liver perfusion; and systemic chemotherapy. There is scope for improvement in the detection of uveal melanoma so as to maximise any opportunities for conserving the eye and vision, as well as preventing metastatic spread. Patient management has been enhanced by the formation of multidisciplinary teams in specialised ocular oncology centres. PMID:22744385

There is a global rising incidence of melanoma. For different reasons, the patterns of the incidence, appearance, gender, anatomical distribution and outcome vary among different geographic areas. Screening programs have led to better early detection of melanoma in Australia and some world areas. National Cancer Registry and practice data show the incidence in Croatia to be constantly rising. Despite public education programs about early detection, at clinical departments there are still many new advanced stage melanoma patients. We analyzed data on 157 patients treated and followed up for 10 years for T1b-T4aN0 skin melanoma. There was a difference in anatomical distribution of melanoma lesions in correlation with patient age (ANOVA test, F=3.51, p=0.009). A higher prevalence of shoulder melanoma was found in young people and of head/neck melanoma in the elderly (post-hoc Sheffe test, p=0.038). T4 lesions were more commonly found in men and T1 mainly in women (Pearson χ(2)-test, χ(2)=12.08, p=0.016). There was no difference in Clark level, but a significantly higher Breslow stage was found in men (t=-2.52, p=0.013). Men were much more prone to have head and neck, body and shoulder melanoma, whereas women had more melanoma on their legs and arms. Clark and Breslow levels were strongly correlated in leg melanoma; head localization showed no correlation at all. In conclusion, more attention should be devoted to improve the results in melanoma detection in men, especially considering the prevalence of body (back) and head/neck localizations, sometimes not readily accessible for visual detection. The pattern of distribution also pointed to the need for more attention to pay to shoulder melanoma in younger people.

Nivolumab-induced vitiligo in a metastatic melanoma patient: A case report.

The programmed-death-1 inhibitors selectively block programmed-death-1 interaction with its receptor, which restores active T-cell response directed at tumor cells, inducing an anti-tumor effect. This nonspecific activation of the immune system can also lead to a wide spectrum of side effects. Nivolumab has been used effectively to prolong survival in patients with metastatic melanoma and is recommended as a category 1 agent for systemic therapy in metastatic or unresectable melanoma per the National Comprehensive Cancer Network guidelines. We present a case of a 64-year-old woman who began nivolumab therapy for metastatic melanoma. After six doses of nivolumab therapy, the patient experienced generalized hypopigmentation on her face, chest, back, arms, and lower extremities. Although vitiligo has been reported in as many as 10.7% of patients undergoing nivolumab therapy in some clinical trials, we believe this is the first case to describe the progression of nivolumab-induced vitiligo in a metastatic melanoma patient. This case provides significant insight into the onset, symptoms, development, and treatment options for patients experiencing vitiligo as a result of nivolumab therapy.

Up-Regulated Dicer Expression in Patients with Cutaneous Melanoma

2011-01-01

Background MicroRNAs (miRNAs) are small non-coding RNAs (18–24 nucleotides) that have recently been shown to regulate gene expression during cancer progression. Dicer, a central enzyme in the multi-component miRNA biogenesis pathway, is involved in cutting precursor miRNAs to functionally mature forms. Emerging evidence shows that Dicer expression is deregulated in some human malignancies and it correlates with tumor progression, yet this role has not yet been investigated in skin cancers. Methods and Findings Using an anti-human monoclonal antibody against Dicer and immunohistochemistry, we compared the expression of Dicer protein among 404 clinically annotated controls and skin tumors consisting of melanocytic nevi (n = 71), a variety of melanomas (n = 223), carcinomas (n = 73) and sarcomas (n = 12). Results showed a cell-specific up-regulated Dicer in 81% of cutaneous, 80% of acrolentiginous and 96% of metastatic melanoma specimens compared to carcinoma or sarcoma specimens (P<0.0001). The expression of Dicer was significantly higher in melanomas compared to benign melanocytic nevi (P<0.0001). In patients with cutaneous melanomas, Dicer up-regulation was found to be significantly associated with an increased tumor mitotic index (P = 0.04), Breslow's depth of invasion (P = 0.03), nodal metastasis (P = 0.04) and a higher American Joint Committee on Caner (AJCC) clinical stage (P = 0.009). Using western blot analysis, we confirmed the cell-specific up-regulation of Dicer protein in vitro. A pooled-analysis on mRNA profiling in cutaneous tumors showed up-regulation of Dicer at the RNA level in cutaneous melanoma, also showing deregulation of other enzymes that participate in the biogenesis and maturation of canonical miRNAs. Conclusions Increased Dicer expression may be a clinically useful biomarker for patients with cutaneous melanoma. Understanding deregulation of Dicer and its influence on miRNA maturation is needed to predict

Malignant melanoma is one kind of malignant disease which has high rates of mortality, metastasis, and poor prognosis. The therapeutic landscape is rapidly changing with the development of novel agents in recent decades, such as anti-PD-1 agents, anti-CTLA-4 agents, and BRAF inhibitors. However, since most of these novel agents are very expensive, not all patients can afford them. Apatinib is a novel oral small-molecule tyrosine kinase inhibitor targeting the intracellular domain of vascular endothelial growth factor receptor 2 (VEGFR-2) and may also be effective on Ret, c-KIT, and c-src. Temozolomide (TMZ) is a second-generation alkylating agent and a cytotoxic drug for melanoma treatment. In this work, we reported a case of metastatic melanoma with an excellent response to apatinib/TMZ combination therapy with progression-free survival for more than one year. This patient showed high expression of CD117, VEGFR-3, and KIT mutation in exon 11, suggesting that apatinib may induce clinical response via inhibiting VEGFR and c-KIT. Apatinib/TMZ combination therapy could be a new option for the treatment of advanced melanoma with KIT mutation.

Worse outcomes have been noted in patients with multiple primary melanomas (MPMs) than in patients with single primary melanomas. We investigated how family history of melanoma and germline CDKN2A mutation status of MPM patients affects risks of developing subsequent melanomas and other cancers and survival outcomes. Comprehensive data on cancer diagnoses and deaths of MPM patients, their first-degree relatives, and matched controls were obtained through Swedish national health care and population registries. Familial MPM cases with germline CDKN2A mutations were youngest at the diagnosis of their second melanoma (median age 42 years) and had among the MPM cohorts the highest relative risks (RR) compared to controls of developing >2 melanomas (RR 238.4, 95% CI 74.8-759.9). CDKN2A mutated MPM cases and their first-degree relatives were the only cohorts with increased risks of nonskin cancers compared to controls (RR 3.6, 95% CI 1.9-147.1 and RR 3.2, 95% CI 1.9-5.6, respectively). In addition, CDKN2A mutated MPM cases had worse survival compared with both cases with familial (HR 3.0, 95% CI 1.3-8.1) and sporadic wild-type MPM (HR 2.63, 95% CI 1.3-5.4). Our study examined outcomes in subgroups of MPM patients, which affected the sample size of the study groups. This study demonstrates that CDKN2A mutation status and family history of melanoma significantly affects outcomes of MPM patients. Copyright © 2017 American Academy of Dermatology, Inc.

The survival rates of melanoma, like any type of cancer, become worse with advancing stage. Spectrum theory is most consistent with the progression of melanoma from the primary site to the in-transit locations, regional or sentinel lymph nodes and beyond to the distant sites. Therefore, early diagnosis and surgical treatment before its spread is the most effective treatment. Recently, new approaches have revolutionized the diagnosis and treatment of melanoma. Genomic profiling and sequencing will form the basis for molecular taxonomy for more accurate subgrouping of melanoma patients in the future. New insights of molecular mechanisms of metastasis are summarized in this review article. Sentinel lymph node biopsy has become a standard of care for staging primary melanoma without the need for a more morbid complete regional lymph node dissection. With recent developments in molecular biology and genomics, novel molecular targeted therapy is being developed through clinical trials. PMID:22892755

The sixth "Melanoma Bridge Meeting" took place in Naples, Italy, December 1st-4th, 2015. The four sessions at this meeting were focused on: (1) molecular and immune advances; (2) combination therapies; (3) news in immunotherapy; and 4) tumor microenvironment and biomarkers. Recent advances in tumor biology and immunology has led to the development of new targeted and immunotherapeutic agents that prolong progression-free survival (PFS) and overall survival (OS) of cancer patients. Immunotherapies in particular have emerged as highly successful approaches to treat patients with cancer including melanoma, non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's disease. Specifically, many clinical successes have been using checkpoint receptor blockade, including T cell inhibitory receptors such as cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death-1 (PD-1) and its ligand PD-L1. Despite demonstrated successes, responses to immunotherapy interventions occur only in a minority of patients. Attempts are being made to improve responses to immunotherapy by developing biomarkers. Optimizing biomarkers for immunotherapy could help properly select patients for treatment and help to monitor response, progression and resistance that are critical challenges for the immuno-oncology (IO) field. Importantly, biomarkers could help to design rational combination therapies. In addition, biomarkers may help to define mechanism of action of different agents, dose selection and to sequence drug combinations. However, biomarkers and assays development to guide cancer immunotherapy is highly challenging for several reasons: (i) multiplicity of immunotherapy agents with different mechanisms of action including immunotherapies that target activating and inhibitory T cell receptors (e.g., CTLA-4, PD-1, etc.); adoptive T cell therapies that include tissue infiltrating lymphocytes (TILs), chimeric antigen receptors (CARs), and

This study describes how melanoma patients used the Internet as a melanoma information source and how it impacted their clinical encounter and treatment decision. From 2010 to 2013, melanoma patients were invited to complete a 23-question paper survey with open- and close-ended questions. Thirty-one of the 62 patients approached completed the survey. The majority (90 %) of respondents used the Internet as a melanoma information source. Most (90 %) had used the search engine Google. The most commonly searched topics were melanoma treatment (96 %), screening (64 %), and prevention (64 %). While most respondents (85 %) found the Internet was a useful melanoma information source, over half (54 %) found melanoma websites at least somewhat difficult to understand. Many (78 %) believed it increased their understanding of their diagnosis, 71 % thought it influenced their treatment decision, and 59 % felt it impacted their specialist consultation. This study informs health care professionals that many melanoma patients search the Internet for information regarding their diagnosis and that it may impact their disease understanding and treatment decisions.

Complete Metabolic Response of Advanced Melanoma to Vemurafenib Assessed with FDG-PET-CT at 85 Hours.

2018-05-01

Vemurafenib improves the management of advanced melanoma due to selective inhibition of the mutated BRAF V600E kinase. FDG-PET-CT is a tool for the evaluation of the biologic impact of inhibiting mutant BRAF. With vemurafenib at day 15, all the patients had at least partial metabolic response. Reductions in uptake correlate with longer progression free survival. In this case, incomplete information provided by the patient led to the performance of his third PET 85 hours after the introduction of vemurafenib. This early case of complete metabolic response suggests that FDG-PET-CT is a useful marker of early biologic response to vemurafenib.

Objectives To evaluate melanoma biopsy specimens for human papilloma virus (HPV) and determine the relation between the presence of HPV, in vitro growth, and clinical progression of melanoma in the patients from whom the biopsy specimens were derived. Summary Background Data Ultraviolet radiation from sun exposure appears to be the primary causal agent in the development of cutaneous melanoma. However, other agents, including HPV, as observed in different epithelial carcinomas, may also play a role in melanoma development and progression. Methods Twelve melanoma biopsy specimens obtained from 12 patients with AJCC stage III and IV melanoma were stained with antibodies against gp-100 (HMB-45) and S-100 protein to confirm melanoma diagnosis and with a polyclonal HPV antibody. After mechanical dissociation, the melanoma specimen cells’ ability to grow in vitro was assessed. Patients were evaluated for melanoma progression with physical examination, complete blood count, and liver function tests every 3 months and a chest radiograph every 6 months. Results All biopsy specimens were positive for S-100, and nine (75%) were positive for gp-100. Seven of 12 (58%) were positive for HPV by immunohistochemistry. In vitro, none of the HPV-negative tumor cells grew from the tumor biopsies, whereas five of seven (71%) of the HPV-positive melanoma tumor cells grew very well. All patients with HPV-positive tumor cells had recurrences and died of melanoma progression, whereas four of five (80%) patients with HPV-negative tumor cells remained alive and without melanoma recurrence. Conclusions The presence of HPV was found in 58% of the biopsy specimens obtained from patients with stage III and IV melanoma and correlated with rapid melanoma progression. HPV may serve as a cofactor in the development of melanoma and may modulate a more aggressive phenotype in HPV-containing melanoma cells. PMID:10767787

LEOPARD syndrome, also known as Gorlin syndrome II, cardiocutaneous syndrome, lentiginosis profusa syndrome, Moynahan syndrome, was more recently coined as Noonan syndrome with multiple lentigines (NSML), inside the RASopathies. Historically, the acronym LEOPARD refers to the presence of distinctive clinical features such as: lentigines (L), electrocardiographic/conduction abnormalities (E), ocular hypertelorism (O), pulmonary stenosis (P), genital abnormalities (A), retardation of growth (R), and sensorineural deafness (D). This condition is identified in 85% of patients with phenotype hallmarks caused by presence a germline point mutation in PTPN11 gene. Association of melanoma to NSML seems to be rare: to our knowledge, two patients so far were reported in the literature. We herein present a patient diagnosed with LEOPARD syndrome, in whom molecular investigation confirmed the presence of the c.1403C>T mutation in exon 12 of the PTPN11 gene, who developed four superficial spreading melanomas and three atypical lentiginous hyperplasias. Three of the melanomas were achromic or hypochromic, three were in situ, and one had a Breslow index under 0.5 mm. Dermoscopic examination showed some characteristic white structures in most of the lesions, which were a signature pattern and a key for the diagnosis. PMID:29445579

Personal attributions for cancer risk involve factors that individuals believe contribute to their risk for developing cancer. Understanding personal risk attributions for melanoma may dictate gene-environment melanoma risk communication strategies. We examined attributions for melanoma risk in a population-based sample of melanoma survivors, first degree family members, and family members who are also parents (N=939). We conducted qualitative examination of open-ended risk attributions and logistic regression examining predictors (demographics, family member type, perceived risk) of the attributions reported (ultraviolet radiation [UVR] exposure, heredity/genetics, phenotype, personal melanoma history, miscellaneous). We found a predominance of risk attributions to UVR and heredity/genetics (80% and 45% of the sample, respectively). Those reporting higher education levels were more likely to endorse attributions to heredity/genetics, as well as to phenotype, than those of lower education levels. First-degree relatives and parent family members were more likely to endorse heredity/genetic attributions than melanoma survivors; melanoma survivors were more likely to endorse personal history of melanoma attributions compared to first-degree relatives and parent family members. These findings inform the development of risk communication interventions for melanoma families. PMID:20809355

Most data on sinonasal mucosal melanoma come from small institutional studies, and therefore optimal treatment methods are not well understood. The purpose of this study was to analyze the association between treatment and survival in sinonasal mucosal melanoma. Six hundred ninety-five patients diagnosed with sinonasal mucosal melanoma between 2004 and 2010 were identified from the National Cancer Data Base. Treatment modalities and overall survival rates were determined. The 5-year overall survival was 21.7%, with a mean survival of 38.4 ± 1.7 months. The majority of patients were treated with surgery alone (31.5%) or surgery with adjuvant radiotherapy (41.4%). There was no statistical difference between survival with surgery alone and surgery with adjuvant radiation therapy (25.1% vs 25.1%, p = 0.93). Between the surgery and surgery-with-adjuvant-therapy groups, there was no difference in the number of patients with positive margins (p = 0.54), regional lymph node metastases at diagnosis (p = 0.55), morbidity scores (p = 0.58), insurance status (p = 0.13), age > 60 years (p = 0.24), or treatment at academic centers (p = 0.12). Based on this large review of patients with sinonasal mucosal melanoma, adjuvant radiation therapy may not provide a survival benefit as patients tended to do poorly regardless of adjuvant radiation status. © 2016 ARS-AAOA, LLC.

Mucosal melanoma is a relatively rare subtype of melanoma for which no clearly established therapeutic strategy exists. The genes of the mTOR signalling pathway have drawn great attention as key targets for cancer treatment, including melanoma. In this study, we aimed to investigate the mutation status of the upstream mTOR regulator TSC1 and evaluated its correlation with the clinicopathological features of mucosal melanoma. We collected 91 mucosal melanoma samples for detecting TSC1 mutations. All the coding exons of TSC1 were amplified by PCR and subjected to Sanger sequencing. Expression level of TSC1 encoding protein (hamartin) was detected by immunohistochemistry. The activation of mTOR pathway was determined by evaluating the phosphorylation status of S6RP and 4E-BP1. The overall mutation frequency of TSC1 was found to be 17.6% (16/91 patients). TSC1 mutations were more inclined to occur in advanced mucosal melanoma (stages III and IV). In the 16 patients with TSC1 mutations, 14 different mutations were detected, affecting 11 different exons. TSC1 mutations were correlated with upregulation of S6RP phosphorylation but were unrelated to 4E-BP1 phosphorylation or hamartin expression. Mucosal melanoma patients with TSC1 mutations had a worse outcome than patients without TSC1 mutations (24.0 versus 34.0 months, P = 0.007). Our findings suggest that TSC1 mutations are frequent in mucosal melanoma. TSC1 mutations can activate the mTOR pathway through phospho-S6RP and might be a poor prognostic predictor of mucosal melanoma. Our data implicate the potential significance of TSC1 mutations for effective and specific drug therapy for mucosal melanoma.

There is a scarcity of real-world data on treatment patterns and outcomes among advanced melanoma patients treated with immunotherapies including ipilimumab, an anti-CTLA-4 antibody approved since 2011. To evaluate ipilimumab and postipilimumab treatment patterns and outcomes among patients with advanced melanoma in Australia, Germany, Italy and Spain, following regulatory approval. Retrospective multicentre, multinational, observational chart review study. Data were extracted from the start of ipilimumab therapy until the end of at least 40 weeks of follow-up, or death. Data from 371 patients (Australia, 103; Germany, 152; Italy, 76; Spain, 40) were analysed. Mean age was 65 years; 62% were male. Eastern Cooperative Oncology Group performance status (ECOG PS) was 0 or 1 for 94%. In 67%, ipilimumab was initially received as second-line or later therapy. Patients received on average 3.4 ipilimumab doses. The ipilimumab-refractory cohort comprised of 226 patients. Of these, 17% in Australia, 47% in Germany, 29% in Italy and 14% in Spain received another antimelanoma treatment after ipilimumab including chemotherapy in 26% and BRAF/other kinase inhibitors in 11%. Ipilimumab-refractory patients who received postipilimumab treatment showed a 40% reduced hazard of dying than those not receiving treatment after ipilimumab (HR 0.60; 95% CI 0.43-0.83), after adjustment for potential confounders. During the time observed, ipilimumab was mainly used as second-line or later therapy. A significant proportion of patients received postipilimumab therapy, most of which was chemotherapy. Nevertheless, overall survival following progression on ipilimumab treatment remained poor, highlighting the need for research to develop more effective end-of-life treatment options. © 2017 European Academy of Dermatology and Venereology.

BRAF mutational testing has become a common practice in the diagnostic process of patients with advanced melanoma. Although time-consuming, DNA sequencing techniques are the current gold standard for mutational testing. However, in certain clinical situations, a rapid test result is required. In this study, the performance of three rapid BRAF mutation tests was compared. Thirty-nine formalin-fixed paraffin-embedded melanoma tissue samples collected between 2007 and 2014 at a single center were included. These samples were analyzed by immunohistochemistry using the anti-BRAF-V600E (VE1) mouse monocolonal antibody (BRAF-VE1 IHC), a V600E-specific Droplet Digital PCR Test, and the Idylla BRAF- Mutation Test (Idylla). Results were compared with the results of conventional BRAF mutation testing, performed using high-resolution melting analysis followed by Sanger sequencing. Next-generation sequencing was performed on samples with discordant results. The Idylla test and Droplet Digital PCR Test correctly identified all mutated and wild-type samples. BRAF-VE1 IHC showed one discordant result. The Idylla test could identify BRAF-V600 mutations other than BRAF-V600E and was the fastest and least laborious test. The Idylla Mutation Test is the most suitable test for rapid BRAF testing in clinical situations on the basis of the broad coverage of treatment-responsive mutations and the fast procedure without the need to perform a DNA isolation step.

The aim of this study was to estimate the cost-of-illness associated with completely resected stage IIIB/IIIC melanoma with macroscopic lymph node involvement, overall and by disease phase, in France, Germany and the UK. This retrospective observational study included patients aged older than or equal to 18 years first diagnosed with stage IIIB/IIIC cutaneous melanoma between 1 January 2009 and 31 December 2011. Data were obtained from medical records and a patient survey. Direct costs, indirect costs and patient out-of-pocket expenses were estimated in euros (€) (and British pounds, £) by collecting resource use and multiplying by country-specific unit costs. National annual costs were estimated using national disease prevalence from the European cancer registry and other published data. Forty-nine centres provided data on 558 patients (58.2% aged <65 years, 53.6% stage IIIB disease at diagnosis). The mean follow-up duration was 27 months (France), 26 months (Germany) and 22 months (UK). The mean total direct cost per patient during follow-up was €23 582 in France, €32 058 in Germany and €37 970 (£31 123) in the UK. The largest cost drivers were melanoma drugs [mean €14 004, €21 269, €29 750 (£24 385), respectively] and hospitalization/emergency treatment [mean: €6634, €6950, €3449 (£2827), respectively]. The total mean indirect costs per patient were €129 (France), €4,441 (Germany) and €1712 (£1427) (UK). Estimates for annual national direct cost were €13.1 million (France), €30.2 million (Germany) and €27.8 (£22.8) million (UK). The economic burden of stage IIIB/IIIC melanoma with macroscopic lymph node involvement was substantial in all three countries. Total direct costs were the highest during the period with distant metastasis/terminal illness.

Ipilimumab is used for the treatment of metastatic melanoma and is associated with serious immune-related colitis. We aimed to report the clinical features, treatment, and outcomes of patients with ipilimumab-induced colitis. In this retrospective observational study, we identified patients with unresectable melanoma treated with ipilimumab between March 2011 and September 2013. Diarrhea was assessed using the Common Terminology Criteria for Adverse Events, v3.0. Colitis was defined by diarrhea (grade≥2) requiring steroids with or without endoscopic/histologic/radiologic evidence of colitis. A total of 103 patients with metastatic melanoma treated with ipilimumab were identified. Of these, 30 patients (29%) developed diarrhea (all grades), and 23 patients (22%) developed colitis requiring systemic corticosteroid therapy. The median number of ipilimumab doses before onset of diarrhea was 2 (range, 1-4). Six of 23 patients responded to less than 1 mg/kg daily prednisone alone. Fifteen patients required high-dose oral and/or intravenous prednisone (1-2 mg/kg body weight). Six patients had diarrhea refractory to prednisone; five required rescue therapy with budesonide (9-12 mg daily) and one was treated with infliximab (5 mg/kg, three doses). There was one case of severe diarrhea (grade 3) treated successfully with high-dose budesonide (12 mg) monotherapy. Ipilimumab-induced colitis requires early and aggressive medical therapy. Most patients can be successfully managed with systemic corticosteroids. High-dose budesonide is an attractive steroid-sparing agent, however further studies of its efficacy in this setting are needed. Infliximab should be used in refractory cases to avoid colectomy.

Ipilimumab can induce durable disease control and long-term survival in patients with metastatic melanoma. Identification of a biomarker that correlates with clinical benefit and potentially provides an early marker of response is an active area of research. Ipilimumab was available upon physician request for patients aged ≥16 years with stage III (unresectable) or IV cutaneous, ocular or mucosal melanoma, who had failed or did not tolerate previous treatments and had no other therapeutic option available. Patients received ipilimumab 3 mg/kg every 3 weeks for four doses. Tumour assessments were conducted at baseline, Week 12 and Week 24 using immune-related response criteria. Patients were monitored continuously for adverse events (AEs), including immune-related AEs. Candidate immunological markers were evaluated in peripheral blood and sera samples collected at baseline and Weeks 4, 7, 10 and 12. Among 95 patients treated with ipilimumab 3 mg/kg, the immune-related disease control rate at Week 24 was 38 %. With a median follow-up of 24 months, median overall survival was 9.6 months. Both disease control and survival were significantly associated with decreasing levels of lactate dehydrogenase, C-reactive protein and FoxP3/regulatory T cells, and increasing absolute lymphocyte count, between baseline and the end of dosing (Week 12). Ipilimumab is a feasible treatment option for heavily pretreated patients with metastatic melanoma. Changes in some immunological markers between baseline and the fourth ipilimumab infusion appear to be associated with disease control and survival, but verification in prospective clinical trials is required.

We conducted a Phase I clinical trial investigating the biologic activity of vaccination with irradiated autologous melanoma cells engineered to secrete human granulocyte--macrophage colony-stimulating factor in patients with metastatic melanoma. Immunization sites were intensely infiltrated with T lymphocytes, dendritic cells, macrophages, and eosinophils in all 21 evaluable patients. Although metastatic lesions resected before vaccination were minimally infiltrated with cells of the immune system in all patients, metastatic lesions resected after vaccination were densely infiltrated with T lymphocytes and plasma cells and showed extensive tumor destruction (at least 80%), fibrosis, and edema in 11 of 16 patients examined. Antimelanoma cytotoxic T cell and antibody responses were associated with tumor destruction. These results demonstrate that vaccination with irradiated autologous melanoma cells engineered to secrete granulocyte--macrophage colony-stimulating factor stimulates potent antitumor immunity in humans with metastatic melanoma.

Summary Cutaneous melanoma, a cancer of melanocytes, when detected at later stages is arguably one of the most lethal cancers and the cause of more years of lost life than any other cancer among young adults. There is no standard therapy for advanced-stage melanoma and the median survival time for patients with metastatic melanoma is <1 yr. An urgent need for novel strategies against melanoma has directed research towards the development of new chemotherapeutic and biologic agents that can target the tumor by several different mechanisms. Recently, several dietary agents are being investigated for their role in the prevention and treatment of various forms of cancer and may represent the future modality of the treatment. Here, we have reviewed emerging data on botanicals that are showing promise for their potential inhibitory effect against cutaneous melanoma. PMID:21426532

Research highlights: {yields} Strong ADAM15 expression is found in normal melanocytes. {yields} ADAM15 expression is significantly downregulated in patients with melanoma metastasis. {yields} TGF-{beta} can downregulate ADAM15 expression in melanoma cells. {yields} Overexpression of ADAM15 in melanoma cells inhibits migration, proliferation and invasion of melanoma cells. {yields} Conclusion: ADAM15 represents an tumor suppressor protein in melanoma. -- Abstract: In a mouse melanoma metastasis model it has been recently shown that ADAM15 overexpression in melanoma cells significantly reduced the number of metastatic nodules on the lung. Unfortunately, the expression of ADAM15 in human melanoma tissue has not been determined so far.more » In our study, we characterized the expression of ADAM15 in tissue micro-arrays of patients with primary melanoma with melanoma metastasis. ADAM15 was expressed in melanocytes and endothelial cells of benign nevi and melanoma tissue. Importantly, ADAM15 was significantly downregulated in melanoma metastasis compared to primary melanoma. We further demonstrate that IFN-{gamma} and TGF-{beta} downregulate ADAM15 protein levels in melanoma cells. To investigate the role of ADAM15 in melanoma progression, we overexpressed ADAM15 in melanoma cells. Importantly, overexpression of ADAM15 in melanoma cells reduced the migration, invasion and the anchorage dependent and independent cell growth of melanoma cells. In summary, the downregulation of ADAM15 plays an important role in melanoma progression and ADAM15 act as a tumorsuppressor in melanoma.« less

Mucosal melanomas constitute 1.3% of all melanomas and they may develop in any mucosal membrane. Conjunctival melanomas (0.5/million/year) and melanomas in the sinonasal cavity (0.5/million/year) are the most common, followed by anorectal melanomas (0.4/million/year) and melanomas in the oral cavity (0.2/million/year). Anorectal melanoma occurs slightly more often in females, whereas oral melanoma has a male predilection. Mucosal melanoma most commonly develops in a patient's sixth or seventh decade of life, and no differences between races have been found except for sinonasal melanoma and conjunctival melanoma, which are very rare in Black people. The symptoms are not tumour-specific and are related to the organ system affected, and the disease is most often diagnosed at an advanced clinical stage. The diagnosis of a primary tumour is difficult, and metastatic cutaneous melanoma and choroidal melanoma must be excluded. Mutations in KIT are frequently found, while BRAF and NRAS mutations are rarely found - except in conjunctival melanomas that carry BRAF mutations. Mutations in the TERT promotor region are also found in mucosal melanomas. Complete surgical resection with free margins is the treatment of choice. The prognosis is poor, with the 5-year survival rate ranging from 0% (gastric melanoma) to 80% (conjunctival melanoma). © 2016 APMIS. Published by John Wiley & Sons Ltd.

Study CA184024 was a multinational, randomised, double-blind, phase 3 study comparing ipilimumab/dacarbazine (DTIC) vs placebo/DTIC in patients with untreated stage III/IV melanoma, which showed that ipilimumab significantly improves survival in patients with metastatic melanoma. The objective of this analysis was to compare the quality-adjusted survival experience among patients in this trial. Survival time was partitioned into health states: toxicity, time before progression without toxicity, and relapse until death or end of follow-up. Q-TWiST (quality-adjusted time without symptoms of disease or toxicity of treatment) was calculated as the utility-weighted sum of the mean health state durations. Analyses were repeated over extended follow-up periods. Based on a combination of trial-based and external utility scores, the Q-TWiST difference in this trial was 0.50 months (P=0.0326) favoring ipilimumab after 1 year. The Q-TWiST difference was 1.5 months with 2 years of follow-up (P=0.0091), 2.36 months at 3 years (P=0.005) and 3.28 months at 4 years (P=0.0074). During the first year of study, there was little difference between groups in quality-adjusted survival. However, after 2, 3 and 4 years follow-up for patients with extended survival, the benefits of IPI+DTIC vs PLA+DTIC for advanced melanoma continue to accrue.

High-dose interleukin-2 (IL-2) for the treatment of melanoma: safety considerations and future directions.

2017-12-01

In 1998, high-dose interleukin-2 (IL-2) was the first immunotherapy approved for the treatment of metastatic melanoma based on durable objective responses documented in a subset of patients but widespread utilization was limited by significant toxicity. Advances in targeted therapy and the emergence of T cell checkpoint inhibitors, which can generally be given in the ambulatory setting, have further limited consideration of IL-2 for melanoma patients and the role of IL-2 in the current landscape of melanoma treatment is uncertain. Areas covered: In this review, we will describe advances in clinical diagnostic and management strategies that have improved the therapeutic window for IL-2 therapy in patients with melanoma. Further, we will describe the potential for using IL-2 in patients whose disease has progressed after other interventions or as part of combination immunotherapy approaches that are now in clinical development. We will also review the common toxicities of IL-2 therapy and their current management will be discussed. Expert opinion: High-dose IL-2 remains an important option for patients with melanoma and has an improved therapeutic window in the contemporary era. The reasons why IL-2 is not utilized more frequently and measures for enhancing its use will be detailed.

Separate Primary Melanomas of the Bulbar Conjunctiva and Eyelid Skin: Clinical Implications of Multiple Primary Melanomas.

We report a patient with previous in situ melanoma of the forehead skin who was referred for treatment of a bulbar conjunctival melanoma and a separate superficially invasive melanoma of the eyelid skin, and we offer a review of the biological and clinical implications of patients who have multiple primary melanomas. This article offers a clinicopathological correlation with a review of the relevant literature. An 80-year-old white man was referred for evaluation of a suspicious conjunctival tumor and a lower-eyelid lesion. Excisional biopsies revealed that both were primary melanomas arising within in situ disease. Over the span of 25 years, the patient had three separate foci of in situ melanoma, two of which spawned invasive melanoma. Separate melanomas arising from the bulbar conjunctiva and eyelid skin have rarely been reported. Multiple primary melanomas of the skin, however, are not uncommon. Based on studies of persons with multiple cutaneous melanomas, the prognosis is best predicted by the tumor with the greatest depth of invasion. Patients with multiple melanomas should be examined for dysplastic nevi, additional cutaneous melanomas, and screened periodically for future lesions. Ongoing studies enrolling patients with multiple primary melanomas are attempting to generate insights into low-penetrance susceptibility genes.

Although melanoma accounts for only 4% of skin cancer cases, it causes 79% of all skin cancer deaths. Patients with metastatic melanoma have a poor prognosis, and long term survival is only about 5% [1, 2]. Conventional therapies such as surgery and radiation therapy usually do not cure stage III or stage IV melanoma, while traditional chemotherapy is primarily palliative. Over the last decade we have been developing new methods for treating solid tumors like melanoma, first in animal models and now in humans. We present here preliminary results from a new technique that utilizes a combination of laser stimulation and drug therapy to stimulate brisk immunological responses in cases of advanced melanoma with cutaneous metastases. A high-power, near-infrared diode laser (805 nm) is used to kill tumors in situ and a topical toll-like receptor agonist (imiquimod cream, 5%) is used to intensify the resulting immunological response. This is essentially an in situ, tumor vaccine approach to treating solid tumors.

Our goal was to evaluate the different subtypes of mucosal melanoma and describe specific variables that predict outcomes. Prospective review of two tertiary care center databases identified 76 mucosal melanoma patients; 73 with complete records were included. Demographic and clinical data were analyzed. Cox regression determined variables impacting recurrence and survival. In the 73 patients, the mean age was 64 years, and 74% were female. Sixty-seven percent presented with lymph node involvement, and 73% had ulcerated tumors. Major sites affected were nasal/palate/oral (36%), vulvar/vaginal/cervical (48%), and anorectal (15%). Mean overall and disease-free survival were 56.9 and 27.2 months. Variables associated with decreased survival included: lymphovascular invasion (HR17.70, P = 0.0093), Caucasian race (HR3.02, P = 0.0362), nasal/palate/oral sub-group (HR1.85, P = 0.026), Breslow thickness (HR1.23, P = 0.00004), T stage (HR1.34, P = 0.0075), M stage (HR3.03, P = 0.0039), and chemotherapy (HR3.13, P = 0.0002). The worst prognosis was seen in the nasal/palate/oral sub-group, with a median overall survival of 9.7 months and recurrence-free time of 4.5 months. This subtype also demonstrated high lymph node positivity, ulceration, and larger tumor size. The nasal, palate, oral subtype has the worst prognosis compared to other mucosal melanoma locations. Studies are ongoing to evaluate pathologic and genomic variables that may predict outcomes. © 2013 Wiley Periodicals, Inc.

This study retrospectively evaluated the toxicity and efficacy of dacarbazine (DTIC) with low-dose subcutaneous interleukin-2 (IL-2) for patients with advanced melanoma. Patients with unresectable malignant melanoma received bio-chemotherapy DTIC (330 mg/m(2) , every 3 weeks ) and IL-2 18 MIU (million international units) in divided doses by subcutaneous injection three times a week for 4 weeks. Treatment was performed for six cycles or until disease progression or unbearable toxicity. From October 2006 to November 2013, up to 31 patients (17 men; 14 women) were enrolled. Their median age was 48 years (range, 22-81 years). Subtypes of melanoma included 11 (35.4%) acral lentiginous, nodular, 1 (3.2%) superficial spreading, 10 (32.2%) mucosal and 5 (16.1%) others. The response rate was 19.3%, including 3.2% with a complete response, 16.1% with a partial response and 6.3% with stable disease. The median progression-free survival time was 3.5 months (95% CI: 3.0-3.9 months). The median overall survival time was 8.6 months (95% CI: 4.1-10.9 months). The 1-year survival rate was 39% and the 5-year survival rate was 10%. Our data demonstrated that low-dose subcutaneous IL-2 plus DTIC has modest efficacy and may produce long-term survival in small proportion of patients. Furthermore, the treatment is well tolerated by patients. © 2015 Wiley Publishing Asia Pty Ltd.

2016-05-01

Advanced unresectable and metastatic non-melanoma skin cancers (NMSC) are rare, but often arise in elderly patients. When surgery or irradiation are no longer feasible, chemotherapy is often precluded by the patient's age and comorbidities. Whether low-dose multi-agent chemotherapy could be an alternative for this vulnerable population in an outpatient setting was the issue examined in this retrospective analysis. Twenty-six patients with advanced unresectable or metastatic NMSC received weekly multi-agent chemotherapy with carboplatin at an area under the curve of 2 or 40 mg total dose of cisplatin, with 15 IU total dose of bleomycin, 40 mg total dose of methotrexate, and 500 mg total dose of 5-fluorouracil (CMF-b) until best response, toxicity, or progression of their disease. Twenty-four patients were treated as outpatients; two were hospitalized. Twenty-three patients were previously treated with surgery or radiotherapy. The median age was 68 years (range=44-100 years). The median number of cycles was 6 (range=1 to 17). The overall response rate was 61.5% (seven complete remissions, nine partial remissions) for the entire cohort and 63.6% (two complete remissions and five partial remissions) for patients >80 years. The median duration of response was 6.1 months (range=1.6-63 months). Responses longer than 6 months were obtained in 11/26 (42.3%) of the entire cohort and in 4/11 (36.3%) patients >80 years. Symptom improvement was observed in 17 patients (65.3%). Toxicity was acceptable, with grade 3 renal failure (n=1) and grade 3 or 4 myelotoxicity (n=2). CMF-b is a safe, weekly low-dose multi-agent regimen that offers palliation for vulnerable patients with NMSC. Copyright© 2016 International Institute of Anticancer Research (Dr. John G.

Background AdCD40L is an immunostimulatory gene therapy under evaluation for advanced melanoma, including ocular melanoma. Herein, we present the final data of a Phase I/IIa trial using AdCD40L alone or in combination with low dose cyclophosphamide +/- radiation therapy. Methods AdCD40L is a replication-deficient adenovirus carrying the gene for CD40 ligand (CD40L). Twenty-four patients with advanced melanoma were enrolled and treated with AdCD40L monotherapy, or combined with cyclophosphamide +/- single fraction radiotherapy. The patients were monitored for 10 weeks using immunological and radiological evaluations and thereafter for survival. Results AdCD40L treatment was safe and well tolerated both alone and in combination with cyclophosphamide as well as local radiotherapy. Four out of twenty-four patients had >1 year survival. Addition of cyclophosphamide was beneficial but adding radiotherapy did not further extend survival. High initial plasma levels of IL12 and MIP3b correlated to overall survival, whereas IL8 responses post-treatment correlated negatively with survival. Interestingly, antibody reactions to the virus correlated negatively with post IL6 and pre IL1b levels in blood. Conclusions AdCD40L was safely administered to patients and effect was improved by cyclophosphamide but not by radiotherapy. Immune activation profile at baseline may predict responders better than shortly after treatment. PMID:29108250

This review aims to summarize the current knowledge of molecular pathways and their clinical relevance in melanoma. Metastatic melanoma was a grim diagnosis, but in recent years tremendous advances have been made in treatments. Chemotherapy provided little benefit in these patients, but development of targeted and new immune approaches made radical changes in prognosis. This would not have happened without remarkable advances in understanding the biology of disease and tremendous progress in the genomic (and other “omics”) scale analyses of tumors. The big problems facing the field are no longer focused exclusively on the development of new treatment modalities, though this is a very busy area of clinical research. The focus shifted now to understanding and overcoming resistance to targeted therapies, and understanding the underlying causes of the heterogeneous responses to immune therapy. PMID:24743024

Uveal melanoma is an aggressive disease without effective adjuvant therapy for metastases. Despite genomic differences between cutaneous and uveal melanomas, therapies based on shared biological factors could be effective against both tumor types. High expression of glycoprotein-NMB (GPNMB) in cutaneous melanomas led to the development of CDX-011 (glembatumumab vedotin), a fully human monoclonal antibody against the extracellular domain of GPNMB conjugated to the cytotoxic microtubule toxin monomethylauristatin E. Ongoing phase II trials suggest that CDX-011 has activity against advanced cutaneous melanomas. To determine the potential role of CDX-011 in uveal melanomas, we studied their GPNMB expression. Paraffin-embedded tissues from 22 uveal melanomas treated by enucleation from 2004-2007 at one institution were evaluated immunohistochemically for expression of GPNMB using biotinylated CDX-011 (unconjugated) antibody. Melanoma cells were evaluated for percentage and intensity of expression. Spectral imaging was used in one case with high melanin content. Clinical data were reviewed. Twelve women and 10 men with a median age of 58.7 years (range: 28-83 years) were included. Eighteen of 21 tumors evaluated immunohistochemically (85.7%) expressed GPNMB in 10-90% of tumor cells with variable intensity (5 tumors, 1+; 11, 2+; and 2, 3+). Eleven of 18 tumors (61.1%) expressed GPNMB in >or=50% of cells. Spectral imaging showed diffuse CDX-011 (unconjugated) reactivity in the remaining case. Uveal melanoma, like cutaneous melanoma, commonly expresses GPNMB. Ongoing clinical trials of CDX-011 should be extended to patients with metastatic uveal melanoma to determine potential efficacy in this subset of patients with melanoma.

Background Hypomelanotic or amelanotic melanomas are challenging to identify, especially at mucosal sites. The dermoscopic clues to the diagnosis of mucosal melanomas have been reported to be structureless zones with the presence of blue, gray, or white colors. Case A female in her seventies noted a new lesion on the inside of her right labia that first appeared two months prior. Her past medical history was significant for rheumatoid arthritis requiring ongoing treatment with methotrexate for 20 years and adalimumab for 10 years. After no response to two weeks of local treatment for suspected herpes simplex infection, her gynecologist performed a skin biopsy. Based on the histopathological diagnosis of an amelanotic melanoma (Breslow thickness of 1.3 mm) the patient was referred to dermatology for further assessment. Polarized dermoscopy revealed a distinct asymmetric, sharply demarcated homogenous white papule (4 × 5 mm) as well as polymorphous vessels. Conclusion Dermoscopy may aid in the diagnosis of amelanotic mucosal melanomas. Our case revealed a structureless white area and polymorphous vessels. Additional clues to the diagnosis were the advanced age of the patient and the clinical presentation of a new lesion. PMID:27867742

Human malignant melanoma is a highly aggressive skin tumor that is characterized by its extraordinary heterogeneity, propensity for dissemination to distant organs and resistance to cytotoxic agents. Although chemo- and immune-based therapies have been evaluated in clinical trials, most of these therapeutics do not show significant benefit for patients with advanced disease. Treatment failure in melanoma patients is attributed mainly to the development of tumor heterogeneity resulting from the formation of genetically divergent subpopulations. These subpopulations are composed of cancer stem-like cells (CSCs) as a small fraction and non-cancer stem cells that form the majority of the tumor mass. In recent years, CSCs gained more attention and suggested as valuable experimental model system for tumor study. In melanoma, intratumoral heterogeneity, progression and drug resistance result from the unique characteristics of melanoma stem cells (MSCs). These MSCs are characterized by their distinct protein signature and tumor growth-driving pathways, whose activation is mediated by driver mutation-dependent signal. The molecular features of MSCs are either in a causal or consequential relationship to melanoma progression, drug resistance and relapse. Here, we review the current scientific evidence that supports CSC hypothesis and the validity of MSCs-dependent pathways and their key molecules as potential therapeutic target for melanoma treatment.

The "SWOT" of BRAF inhibition in melanoma: RAF inhibitors, MEK inhibitors or both?

PubMed

Nissan, Moriah H; Solit, David B

2011-12-01

Activating mutations in the BRAF gene are among the most prevalent kinase mutations in human cancer. BRAF mutations are most frequent in patients with melanoma where they occur in approximately 50% of patients with advanced disease. Remarkable clinical activity has recently been reported with highly selective RAF inhibitors in melanoma patients whose tumors harbor V600E BRAF mutations. The response rates of RAF inhibitors in patients with BRAF-mutant melanomas far exceed the activity level of any prior therapy studied in this disease. The results suggest that we have entered an era of personalized therapy for patients with metastatic melanoma in which treatment selection will be guided by BRAF mutational status. This review will discuss the strengths, weaknesses, opportunities and threats ("SWOT") of developing RAF and MEK selective inhibitors as anti-cancer therapies, recent insights into the mechanisms of intrinsic and acquired resistance to these agents, and current efforts to develop mechanism-based combination therapies.

Therapeutic antibodies against programmed cell death receptor 1 (PD-1) are considered front-line therapy in metastatic melanoma. The efficacy of PD-1 blockade for patients with biologically distinct melanomas arising from acral and mucosal surfaces has not been well described. A multi-institutional, retrospective cohort analysis identified adults with advanced acral and mucosal melanoma who received treatment with nivolumab or pembrolizumab as standard clinical practice through expanded access programs or published prospective trials. Objective responses were determined using investigator-assessed Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Progression-free survival and overall survival were assessed using the Kaplan-Meier method. Sixty individuals were identified, including 25 (42%) with acral melanoma and 35 (58%) with mucosal melanoma. Fifty-one patients (85%) had received previous therapy, including 77% who had previously received ipilimumab. Forty patients (67%) received pembrolizumab at a dose of 2 mg/kg or 10 mg/kg, and 20 (33%) received nivolumab at a doses ranging from 0.3 to 10 mg/kg every 2 to 3 weeks. The objective response rate was 32% (95% confidence interval, 15%-54%) in patients with acral melanoma and 23% (95% confidence interval, 10%-40%) in those with mucosal melanoma. After a median follow-up of 20 months in the acral melanoma group and 10.6 months in the mucosal melanoma group, the median progression-free survival was 4.1 months and 3.9 months, respectively. Only 2 patients (3%) discontinued treatment because of toxicity. Response rates to PD-1 blockade in patients with acral and mucosal melanomas were comparable to the published rates in patients with cutaneous melanoma and support the routine use of PD-1 blockade in clinical practice. Further investigation is needed to identify the mechanisms of response and resistance to therapy in these subtypes. Cancer 2016;122:3354-3362. © 2016 American Cancer Society. © 2016

Cancer survival rates are lower in Eastern Europe. To describe, based on a single-centre database in northern Italy, clinical, histopathological, and prognostic features of melanoma in a migrant population from Eastern Europe. We retrospectively analysed data from 18,190 consecutive foreign patients who visited our institution, with 49 cases of melanoma from Eastern Europe. The control group was represented by 1,003 Italian melanoma patients diagnosed and followed at our centre during the same time period. Patients from Eastern Europe were mainly females with lower median age, without significant differences regarding primary melanoma site, relative to the control group. Diagnosis was made at the place of birth in 30.6% and in our centre for the remainder. Median Breslow thickness was greater (p = 0.0178), and aggressive histotypes (p = 0.0017) and ulcerated melanomas (p = 0.002) were significantly over-represented, particularly when diagnosed in the patients' native country. Disease was more advanced at diagnosis (p = 0.0001), regardless of the place of initial diagnosis (51% had a progressive disease within one year which rose to 80% if diagnosed before admission to our centre), and the percentage of patients who died within one year was significantly higher (p = 0.022), relative to the control group. Our study shows a poor prognosis for melanoma patients diagnosed in Eastern Europe. Moreover, for migrant populations moving from Eastern to Western European countries, financial difficulties, poor social integration, and language barriers, with consequent late access to healthcare facilities, may account for a worse prognosis.

Metastatic melanoma - a review of current and future drugs.

Velho, Tiago Rodrigues

2012-11-19

Melanoma is one of the most aggressive cancers, and it is estimated that 76,250 men and women will be diagnosed with melanoma of the skin in the USA in 2012. Over the last few decades many drugs have been developed but only in 2011 have new drugs demonstrated an impact on survival in metastatic melanoma. A systematic search of literature was conducted, and studies providing data on the effectiveness of current and/or future drugs used in the treatment of metastatic melanoma were selected for review. This review discusses the advantages and limitations of these agents, evaluating past, current and future clinical trials designed to overcome such limitations. To date, there are four drugs approved by the Food and Drug Administration for melanoma (dacarbazine, interleukin-2, ipilimumab and vemurafenib). Despite efforts to develop new drugs, few of them have demonstrated any clinical benefits. Approved in 1975, dacarbazine remains the gold standard in chemotherapy, although ipilimumab and vemurafenib have raised many hopes in the last few years. Combining dacarbazine or other chemotherapy agents with new pharmacological agents may be a new way to achieve better clinical responses in patients with metastatic melanoma. Advances in the molecular knowledge of melanoma have led to major improvements in the treatment of patients with metastatic melanoma, providing new targets and insights. However, heterogeneity amongst study populations, different approaches to treatment and the different melanoma types and localisations included in the trials makes their comparison difficult. New studies focusing on drugs developed in recent decades are warranted.

The cost of unresectable stage III or stage IV melanoma in Italy

PubMed Central

2012-01-01

Background In recent decades, melanoma incidence has been increasing in European countries; in 2006, there were approximately 60,000 cases leading to 13,000 deaths. Within Europe there is some geographical variation in the incidence of melanoma, with the highest rates reported in Scandinavia (15 cases per 100,000 inhabitants per year) and the lowest in the Mediterranean countries (5 to 7 cases per 100,000 inhabitants per year). Methods The present article is based on the information collected in the MELODY study (MELanoma treatment patterns and Outcomes among patients with unresectable stage III or stage IV Disease: a retrospective longitudinal survey). In that study, the medical charts of patients were reviewed to document current treatment patterns and to analyse information on patients, disease characteristics and healthcare resource utilization related to the treatment of advanced melanoma regarding patients who presented with a diagnosis of malignant melanoma (stage I to IV) at participating sites between 01 July, 2005 and 30 June, 2006. Results Summarizing, though the length of the follow-up period varies among sample patients, an amount of the yearly cost per patient can be estimated, dividing the average per patient total cost (€ 5.040) by the average follow-up duration (17.5 months) and reporting to one year; on these grounds, unresectable stage III or stage IV melanoma in Italy would cost € 3,456 per patient per year.

We reported an 81-year-old woman with metastatic melanoma, in whom myasthenia gravis and rhabdomyolysis developed after nivolumab monotherapy. The first symptom of myasthenia gravis was dyspnea. Ultrasonography detected hypokinesis of the bilateral diaphragm suggesting myasthenia gravis, although there was no abnormal finding of the lungs in computed tomography images. Acetylcholine receptor binding antibodies were low-titer positive in the preserved serum before administration of nivolumab, strongly suggesting that the myasthenia gravis was a nivolumab-related immune adverse event. Despite the remarkable clinical benefits of immune checkpoint inhibitors for patients with advanced melanoma, it is important to recognize unexpected immune-related adverse events. © The Author 2015.

Most melanoma studies use data from the National Cancer Institute Surveillance, Epidemiology, and End Results Program or individual cancer registries. Small numbers of melanoma cases have limited in-depth analyses for all racial and ethnic groups. We sought to describe racial and ethnic variations in melanoma incidence and survival. Incidence for invasive melanoma and 5-year melanoma-specific survival were calculated for whites, blacks, American Indians/Alaskan Natives, Asians/Pacific Islanders (API), and Hispanics using data from 38 population-based cancer registries. Incidence rates of melanoma were significantly higher for females than males among whites and Hispanics under 50 years of age and APIs under 40 years of age. White and black patients were older (median age: 59-63 years) compared with Hispanics, American Indians/Alaskan Natives, and API (median age: 52-56 years). The most common histologic type was acral lentiginous melanoma among blacks and superficial spreading melanoma among all other racial and ethnic groups. Hispanics had the highest incidence rate of acral lentiginous melanoma, significantly higher than whites and API. Nonwhites were more likely to have advanced and thicker melanomas at diagnosis and lower melanoma-specific survival compared with whites. Over 50% of melanoma cases did not have specified histology. The numbers of nonwhite patients were still relatively small despite broad population coverage (67% of United States). Racial and ethnic differences in age at melanoma diagnosis, anatomic sites, and histologic types suggest variations in etiologic pathways. The high percentages of advanced and thicker melanomas among nonwhites highlight the need to improve melanoma awareness for all race and ethnicity in the United States.

Nivolumab is a monoclonal antibody directed against programmed death-1 that has been shown to improve survival in patients with metastatic melanoma. However, the efficacy of nivolumab and other agents in melanoma remains limited. The objective of this study was to evaluate the efficacy and safety of retreatment with nivolumab in metastatic melanoma patients who previously progressed on nivolumab. A retrospective review was performed on eight consecutive metastatic melanoma patients retreated with nivolumab who progressed on previous nivolumab. These patients received nivolumab 2 mg/kg every 3 weeks. Best responses to each treatment were assessed using RECIST 1.1. Of eight metastatic melanoma patients, three patients received chemotherapy before first nivolumab. The median first nivolumab treatment period was 4.1 months. During first nivolumab, 3 (37.5%) patients achieved a partial response and 3 (37.5%) patients achieved stable disease as their best response. First nivolumab was discontinued due to disease progression in seven patients and grade 3 colitis in 1 patient. Patients were subsequently treated with ipilimumab (n = 6), vemurafenib (n = 1), or no other medical treatment (n = 1). The median treatment period between first and second nivolumab was 3.0 months. Four patients received radiation therapy between first and second nivolumab. The median second nivolumab treatment period was 4.3 months. Among the eight patients who received second nivolumab, 2 (25%) patients achieved a partial response and 3 (37.5%) patients achieved stable disease as their best response. Second nivolumab was discontinued due to disease progression in seven patients. One patient continues to receive second nivolumab. Among the four patients treated with ipilimumab and radiotherapy between first and second nivolumab, the response rate was 50% and the disease control rate was 75%. This study showed that retreatment with nivolumab is an option for select metastatic melanoma

Objective To assess the relative effectiveness and cost-effectiveness of seven new drugs (cobimetinib, dabrafenib, ipilimumab, nivolumab, pembrolizumab, trametinib and vemurafenib) used for treatment of patients with advanced malignant melanoma in the Norwegian setting. Design A multiple technology assessment. Patients Patients with advanced malignant melanoma aged 18 or older. Data sources A systematic search for randomised controlled trials in relevant bibliographic databases. Methods We performed network meta-analyses using both direct and indirect evidence with dacarbazine as a common comparator. We ranked the different treatments in terms of their likelihood of leading to the best results for each endpoint. The cost-utility analysis was based on a probabilistic discrete-time Markov cohort model. The model calculated the costs and quality-adjusted life years (QALYs) with different treatment strategies from a healthcare perspective. Sensitivity analysis was performed by means of Monte Carlo simulation. Results Monotherapies with a programmed cell death 1 (PD-1) immune-checkpoint-inhibitor had a higher probability of good performance for overall survival than monotherapies with ipilimumab or BRAF/MEK inhibitors. The combination treatments had all similar levels of effectiveness to the PD-1 immune-checkpoint-inhibitors. PD-1 immune-checkpoint-inhibitors are more effective and more costly compared with ipilimumab in monotherapy. Nivolumab in combination with ipilimumab had higher costs and the same level of effectiveness as the PD-1 immune-checkpoint-inhibitors in monotherapy. BRAF/MEK inhibitor combinations (dabrafenib and trametinib or vemurafenib and cobimetinib) had both similar effectiveness and cost-effectiveness; however, the combination therapies are more likely to give higher quality adjusted life year gains than BRAF or MEK inhibitor monotherapies, but to a higher cost. Conclusions None of the drugs investigated can be considered cost-effective at what

Most melanomas present as primary tumors on the skin surface in adults; however, melanomas also arise in the eye and on the mucosal surfaces or present as apparently metastatic disease without any known history of a cutaneous primary. Melanoma is also being diagnosed during childhood more frequently than ever. Surgeons need to be aware of and understand these unusual presentations of melanoma to optimally manage their patients.

Melanoma patients with regional metastatic disease are at high risk for recurrence and metastatic disease, despite radical lymph node dissection (RLND). We investigated the immunologic response and clinical outcome to adjuvant dendritic cell (DC) vaccination in melanoma patients with regional metastatic disease who underwent RLND with curative intent. In this retrospective study, 78 melanoma patients with regional lymph node metastasis who underwent RLND received autologous DCs loaded with gp100 and tyrosinase and were analyzed for functional tumor-specific T cell responses in skin-test infiltrating lymphocytes. The study shows that adjuvant DC vaccination in melanoma patients with regional lymph node metastasis is safe and induced functional tumor-specific T cell responses in 71% of the patients. The presence of functional tumor-specific T cells was correlated with a better 2-year overall survival (OS) rate. OS was significantly higher after adjuvant DC vaccination compared to 209 matched controls who underwent RLND without adjuvant DC vaccination, 63.6 mo vs. 31.0 mo (p = 0.018; hazard ratio 0.59; 95%CI 0.42–0.84). Five-year survival rate increased from 38% to 53% (p < 0.01). In summary, in melanoma patients with regional metastatic disease, who are at high risk for recurrence and metastatic disease after RLND, adjuvant DC vaccination is well tolerated. It induced functional tumor-specific immune responses in the majority of patients and these were related to clinical outcome. OS was significantly higher compared to matched controls. A randomized clinical trial is needed to prospectively validate the efficacy of DC vaccination in the adjuvant setting. PMID:26942068

Among 10,068 incident cases of invasive melanoma, we examined the effects of patient characteristics and access-to-care on the risk of advanced melanoma. Access-to-care was defined in terms of census tract-level sociodemographics, health insurance, cost of dermatological services and appointment wait-times, clinic density and travel distance. Public health insurance and education level were the strongest predictors of advanced melanomas but were modified by race/ethnicity and poverty: Hispanic whites and high-poverty neighborhoods were worse off than non-Hispanic whites and low-poverty neighborhoods. Targeting high-risk, underserved Hispanics and high-poverty neighborhoods (easily identified from existing data) for early melanoma detection may be a cost-efficient strategy to reduce melanoma mortality.

A new US Food and Drug Administration (FDA) regulation classified tanning beds as class II, requiring indoor tanning facilities to inform users of the risk of skin cancer in efforts to reverse the growing trend in indoor tanning. However, little is known from the patient's perspective on whether knowledge of the risk of skin cancer development is a deterrent to indoor tanning. There also is conflicting literature regarding the relationship among frequency of indoor tanning, age at onset of melanoma diagnosis, and characteristics of diagnosis in melanoma patients with a history of indoor tanning. An international survey was conducted in patients 18 years and older who self-reported being diagnosed with melanoma after indoor tanning. The purpose of this study was to investigate the patients' perspective on indoor-tanning behaviors as associated with the severity of their melanomas and the time frame in which they were diagnosed as well as their perceived views on the safety of indoor tanning and the frequency in which they continue to tan indoors.

We examined nevi and melanomas in 10 xeroderma pigmentosum (XP) patients with defective DNA repair. The lesions had a lentiginous appearance with markedly increased numbers of melanocytes. Using laser capture microdissection, we performed DNA sequencing of 18 benign and atypical nevi and 75 melanomas (melanoma in situ and invasive melanomas). The nevi had a similar high frequency of PTEN mutations as melanomas [61% (11/18) versus 53% (39/73)]. Both had a very high proportion of UV-type mutations (occurring at adjacent pyrimidines) [91% (10/11) versus 92% (36/39)]. In contrast to melanomas in the general population, the frequency of BRAF mutations (11%, 7/61), NRAS mutations (21%, 13/62), and KIT mutations (21%, 6/28) in XP melanomas was lower than for PTEN. Phospho-S6 immunostaining indicated activation of the mTOR pathway in the atypical nevi and melanomas. Thus, the clinical and histological appearances and the molecular pathology of these UV-related XP nevi and melanomas were different from nevi and melanomas in the general population. © 2014 Published 2014.

Sherrill, B; Wang, J; Kotapati, S; Chin, K

2013-01-01

Background: Study CA184024 was a multinational, randomised, double-blind, phase 3 study comparing ipilimumab/dacarbazine (DTIC) vs placebo/DTIC in patients with untreated stage III/IV melanoma, which showed that ipilimumab significantly improves survival in patients with metastatic melanoma. The objective of this analysis was to compare the quality-adjusted survival experience among patients in this trial. Methods: Survival time was partitioned into health states: toxicity, time before progression without toxicity, and relapse until death or end of follow-up. Q-TWiST (quality-adjusted time without symptoms of disease or toxicity of treatment) was calculated as the utility-weighted sum of the mean health state durations. Analyses were repeated over extended follow-up periods. Results: Based on a combination of trial-based and external utility scores, the Q-TWiST difference in this trial was 0.50 months (P=0.0326) favoring ipilimumab after 1 year. The Q-TWiST difference was 1.5 months with 2 years of follow-up (P=0.0091), 2.36 months at 3 years (P=0.005) and 3.28 months at 4 years (P=0.0074). Conclusion: During the first year of study, there was little difference between groups in quality-adjusted survival. However, after 2, 3 and 4 years follow-up for patients with extended survival, the benefits of IPI+DTIC vs PLA+DTIC for advanced melanoma continue to accrue. PMID:23787916

The melanoma research alliance: the power of patient advocacy to accelerate research and novel therapies.

PubMed

Black, Debra; Brockway-Lunardi, Laura

2013-12-01

Patient advocacy organizations play a major role in accelerating research and are particularly important in a disease like melanoma, for which there is an urgent need for new tools and treatments. Melanoma is a growing public health burden. In the United States alone, the incidence of melanoma has tripled over the past 30 years, and one American dies every hour from the disease. To accelerate the field, the Melanoma Research Alliance (MRA) was founded in 2007 and is now the largest private funder of melanoma research, having invested more than $48 million in innovative and translational research projects worldwide to date. This investment is bearing fruit in the recent transformation of the melanoma clinical landscape, which has brought new hope to patients and their families. Yet, even with new drugs on the market, much more needs to be done until melanoma is effectively addressed. MRA is part of a growing group of nonprofit disease research foundations collectively called "venture philanthropies" that are playing a powerful role in transforming the outlook for their disease by overcoming barriers that bog down progress, targeting key areas, and enhancing collaboration. MRA is leading an innovative agenda to accelerate efforts on behalf of patients. Our goal, while significant, is straightforward: to end suffering and death due to melanoma. ©2013 AACR.

Piroti, Georgia; Papadodima, Olga

2018-01-01

Melanoma is a lethal type of skin cancer, unless it is diagnosed early. Formalin-fixed, paraffin-embedded (FFPE) tissue is a valuable source for molecular assays after diagnostic examination, but isolated nucleic acids often suffer from degradation. Here, for the first time, we examine primary melanomas from Greek patients, using whole exome sequencing, so as to derive their mutational profile. Application of a bioinformatic framework revealed a total of 10,030 somatic mutations. Regarding the genes containing putative protein-altering mutations, 73 were common in at least three patients. Sixty-five of these 73 top common genes have been previously identified in melanoma cases. Biological processes related to melanoma were affected by varied genes in each patient, suggesting differences in the components of a pathway possibly contributing to pathogenesis. We performed a multi-level analysis highlighting a short list of candidate genes with a probable causative role in melanoma. PMID:29596374

Vaccines against advanced melanoma.

Research shows that cancers are recognized by the immune system but that the immune recognition of tumors does not uniformly result in tumor rejection or regression. Quantitating the success or failure of the immune system in tumor elimination is difficult because we do not really know the total numbers of encounters of the immune system with the tumors. Regardless of that important issue, recognition of the tumor by the immune system implicitly contains the idea of the tumor antigen, which is what is actually recognized. We review the molecular identity of all forms of tumor antigens (antigens with specific mutations, cancer-testis antigens, differentiation antigens, over-expressed antigens) and discuss the use of these multiple forms of antigens in experimental immunotherapy of mouse and human melanoma. These efforts have been uniformly unsuccessful; however, the approaches that have not worked or have somewhat worked have been the source of many new insights into melanoma immunology. From a critical review of the various approaches to vaccine therapy we conclude that individual cancer-specific mutations are truly the only sources of cancer-specific antigens, and therefore, the most attractive targets for immunotherapy.

Sentinel node biopsy is a standard method for nodal staging in patients with clinically localized cutaneous melanoma, but the survival advantage of sentinel node biopsy remains unsolved. The aim of this case-control study was to investigate the survival benefit of sentinel node biopsy. A total of 305 prospective melanoma patients undergoing sentinel node biopsy were compared with 616 retrospective control patients with clinically localized melanoma whom have not undergone sentinel node biopsy. Survival differences were calculated with the median follow-up time of 71 months in sentinel node biopsy patients and 74 months in control patients. Analyses were calculated overall and separately in males and females. Overall, there were no differences in relapse-free survival or cancer-specific survival between sentinel node biopsy patients and control patients. Male sentinel node biopsy patients had significantly higher relapse-free survival ( P = 0.021) and cancer-specific survival ( P = 0.024) than control patients. In females, no differences were found. Cancer-specific survival rates at 5 years were 87.8% in sentinel node biopsy patients and 85.2% in controls overall with 88.3% in male sentinel node biopsy patients and 80.6% in male controls and 87.3% in female sentinel node biopsy patients and 89.8% in female controls. Sentinel node biopsy did not improve survival in melanoma patients overall. While females had no differences in survival, males had significantly improved relapse-free survival and cancer-specific survival following sentinel node biopsy.

Malignant melanoma is the most aggressive and deadly form of skin cancer. Dacarbazine (DTIC) has been the approved first-line treatment for metastatic melanoma in routine clinical practice. However, response rates with single-agent DTIC are low. The objective of this study was to compare the efficacy and safety of DTIC with or without placebo and DTIC-based combination therapies in patients with advanced metastatic melanoma. We searched from electronic databases such as The Cochrane Library, MEDLINE, EBSCO, EMBASE, Ovid, CNKI, and CBMDisc from 2003 to 2013. The primary outcome measures were overall response and 1-year survival, and the secondary outcome measurements were adverse events. Nine randomized controlled trials (RCTs) involving 2,481 patients were included in the meta-analysis. DTIC-based combination therapies was superior to DTIC alone in overall response (combined risk ratio [RR]  = 1.60, 95% confidence interval [CI]: 1.27-2.01) and 1-year survival (combined RR = 1.26, 95% CI: 1.14-1.39). Patients with DTIC-based combination therapies had higher incidence of adverse events including nausea (combined RR = 1.23, 95% CI: 1.10-1.36), vomiting (combined RR = 1.73, 95% CI: 1.41-2.12) and neutropenia (combined RR = 1.75, 95% CI: 1.42-2.16) compared to the group for DTIC alone. These data suggested that DTIC-based combination therapies could moderately improve the overall response and the 1-year survival but increased the incidence of adverse events. Further large-scale, high-quality, placebo-controlled, double-blind trials are needed to confirm this conclusion.

Cutaneous malignant melanoma (CMM) is currently the most fatal of skin cancers accounting for 50000 deaths annually. Five distinct melanomas are described histopathologically: superficial spreading, lentigo maligna, nodular, acral lentiginous and mucosal melanoma. The aim of this study was to investigate the characteristics of patients with various types of malignant melanoma and evaluate histopathological findings. In this retrospective study, we obtained our data from the records of 111 patients with melanoma. Biopsied specimens were collected and re-evaluated. Demographic information and histopathological findings were noted. SPSS 16 was used for analyzing data. Chi-square and one-way ANOVA was conducted for comparing categorical and numerical variables respectively. The mean age of patients was 59.33±14.68 years old. Most common melanoma type was acral lentiginous (40.5%), followed by nodular (35.1%) and mucosal (10.8%). The highest tumor thickness was viewed in nodular melanoma followed by mucosal melanoma. The highest rate of metastasis, microsatellitosis, perineural invasion and Clark level of the invasion were reported in nodular and acral lentiginous respectively. The most frequent rate of ulceration and vascular invasion was reported in mucosal melanoma. Distribution of melanoma types varies largely in different regions. Lack of classic presentations in some types necessitate specific public education about warning signs. Histopathological and pathological characteristics in melanoma can aid in better staging and management of the tumor.

KIT-directed tyrosine kinase inhibitors such as imatinib have demonstrated benefits in KIT-mutant (KIT+) mucosal, acral, vulvovaginal, and chronically sun-damaged (CSD) melanoma. Dasatinib has superior preclinical activity in comparison with other tyrosine kinase inhibitors against cells with the most common KIT mutation, exon 11 L576P . The ECOG-ACRIN E2607 trial assessed dasatinib in patients with these melanoma subtypes. Patients received 70 mg of oral dasatinib twice daily. The primary objective for this 2-stage phase 2 trial was response rate. Stage I was open to KIT+ and wild-type KIT (KIT-) mucosal, acral, and CSD melanoma (n = 57). Stage II accrued only KIT+ tumors (n = 30). To enrich the trial for KIT+ tumors, vulvovaginal melanoma was added, and CSD melanoma was removed from eligibility. Secondary objectives included progression-free survival (PFS), overall survival (OS), and safety. From May 2009 to December 2010, the first stage enrolled 57 patients. Among the evaluable patients, 3 of 51 (5.9%) achieved a partial response: all were KIT-. Stage II closed early because of slow accrual (November 2011 to December 2015). In stage II, 4 of 22 evaluable patients (18.2%) had a partial response; the median duration was 4.2 months. The median PFS was 2.1 months (n = 73; 95% confidence interval [CI], 1.5-2.9 months). The median OS was 7.5 months (95% CI, 6.0-11.9 months). In exploratory analyses, no differences were seen in PFS or OS with the KIT status or subtype. Dasatinib was discontinued because of adverse events in 9 of 75 patients (12%). The dasatinib response rate among KIT+ melanoma patients was low. In view of its clinical activity, it is recommended that imatinib remain the KIT tyrosine kinase inhibitor of choice for unresectable KIT+ melanoma.

BRAF V600 , NRAS, TP53, and BRAF Non-V600 are among the most common mutations detected in non-acral cutaneous melanoma patients. Although several studies have identified clinical and pathological features associated with BRAF V600 and NRAS mutations, limited data are available regarding the correlates and significance of TP53 and BRAF Non-V600 mutations. This study analyzed the patient demographics, primary tumor features, and clinical outcomes of a large cohort of non-acral cutaneous melanoma patients who had undergone clinically indicated molecular testing (n = 926). The prevalence of BRAF V600 , NRAS, TP53, and BRAF Non-V600 mutations was 43%, 21%, 19%, and 7%, respectively. The presence of a TP53 mutation was associated with older age (P = .019), a head and neck primary tumor site (P = .0001), and longer overall survival (OS) from the diagnosis of stage IV disease in univariate (P = .039) and multivariate analyses (P = .015). BRAF Non-V600 mutations were associated with older age (P = .005) but not with primary tumor features or OS from stage IV. Neither TP53 nor BRAF Non-V600 mutations correlated significantly with OS with frontline ipilimumab treatment, and the TP53 status was not significantly associated with outcomes with frontline BRAF inhibitor therapy. Eleven patients with BRAF Non-V600 mutations were treated with a BRAF inhibitor. Three patients were not evaluable for a response because of treatment cessation for toxicities; the remaining patients had disease progression as the best response to therapy. These results add to the understanding of the clinical features associated with TP53 and BRAF Non-V600 mutations in advanced cutaneous melanoma patients, and they support the rationale for evaluating the prognostic significance of TP53 in other cohorts of melanoma patients.

Importance Previous studies have reported that histopathologically amelanotic melanoma is associated with poorer survival than pigmented melanoma; however, small numbers of amelanotic melanomas, selected populations, lack of centralized pathology review, or no adjustment for stage limit interpretation or generalization of results from prior studies. Objective To compare melanoma-specific survival between patients with histopathologically amelanotic and those with pigmented melanoma in a large international population-based study. Design Survival analysis with median follow-up of 7.6 years. Setting The Genes, Environment, and Melanoma study enrolled incident cases of melanoma diagnosed in 1998-2003 from international population-based cancer registries. Participants A total of 2,995 patients with 3,486 invasive primary melanomas centrally scored for histologic pigmentation. Main Outcomes and Measurements Clinicopathologic predictors and melanoma-specific survival of histologically amelanotic and pigmented melanoma were compared using generalized estimating equations and Cox regression models, respectively. Results Eight percent of melanomas (275 of 3,467) were histopathologically amelanotic. Female sex, nodular and unclassified or other histologic subtypes, increased Breslow thickness, presence of mitoses, severe solar elastosis, and lack of a co-existing nevus were independently associated with amelanotic melanoma (each P < .05). Amelanotic melanoma was generally of a higher American Joint Committee on Cancer (AJCC) tumor stage at diagnosis (P for trend <.001) than pigmented melanoma. Hazard of death from melanoma was higher for amelanotic than pigmented melanoma [hazard ratio (HR), 2.0; 95% confidence interval (CI), 1.4-3.0; P< .001], adjusted for age, sex anatomic site, and study design variables; but survival did not differ once AJCC tumor stage was also taken into account, (HR, 0.8; 95% CI, 0.5-1.2; P = .36).

Melanoma remains mostly an untreatable fatal disease despite advances in decoding cancer genomics and developing new therapeutic modalities. Progress in patient care would benefit from additional predictive models germane for human disease mechanisms, tumor heterogeneity, and therapeutic responses. Toward this aim, this review documents comparative aspects of human and naturally occurring canine melanomas. Clinical presentation, pathology, therapies, and genetic alterations are highlighted in the context of current basic and translational research in comparative oncology. Somewhat distinct from sun exposure-related human cutaneous melanomas, there is growing evidence that a variety of gene copy number alterations and protein structure/function mutations play roles in canine melanomas, in circumstances more analogous to human mucosal melanomas and to some extent other melanomas with murine sarcoma viral oncogene homolog B (BRAF), Neuroblastoma RAS Viral (V-Ras) Oncogene Homolog (NRAS), and neurofibromin 1 tumor suppressor NF1 triple wild-type genotype. Gaps in canine genome annotation, as well as an insufficient number and depth of sequences covered, remain considerable barriers to progress and should be collectively addressed. Preclinical approaches can be designed to include canine clinical trials addressing immune modulation as well as combined-targeted inhibition of Rat Sarcoma Superfamily/Mitogen-activated protein kinase (RAS/MAPK) and/or Phosphatidylinositol-3-Kinase/Protein Kinase B/Mammalian target of rapamycin (PI3K/AKT/mTOR) signal transduction, pathways frequently activated in both human and canine melanomas. Future investment should be aimed towards improving understanding of canine melanoma as a predictive preclinical surrogate for human melanoma and for mutually benefiting these uniquely co-dependent species.

Background Therapeutic antibodies against programmed death receptor 1 (PD-1) are considered front-line therapy in metastatic melanoma. The efficacy of PD-1 blockade for patients with biologically distinct melanomas arising from acral and mucosal surfaces has not been well described. Methods A multi-institutional retrospective cohort analysis identified adults with advanced acral and mucosal melanoma treated with nivolumab or pembrolizumab as standard clinical practice, via expanded access programs, or published prospective trials. Objective responses were determined utilizing investigator-assessed Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Progression-free (PFS) and overall survival (OS) were assessed using Kaplan-Meier methods. Results 60 individuals were identified; 25 (42%) with acral and 35 (58%) with mucosal melanoma. Fifty-one (85%) patients had received prior therapy, including 77% with prior ipilimumab. Forty patients (67%) received pembrolizumab at 2mg/kg or 10mg/kg and 20 (33%) received nivolumab at 1mg/kg or 3mg/kg every 2–3 weeks. ORR (95% confidence interval, CI) was 32% (15–54%) in acral and 23% (10–40%) in mucosal melanoma. After a median follow up of 20 months in acral and 10.6 months in mucosal, median PFS was 4.1 months and 3.9 months, respectively. Only two patients (3%) discontinued treatment due to toxicity. Conclusions Response rates to PD-1 blockade in patients with acral and mucosal melanomas were comparable to published rates in cutaneous melanoma and support the routine use of PD-1 blockade in clinical practice. Further investigation is needed to identify the mechanisms of response and resistance to therapy in these subtypes. PMID:27533633

To determine potential prognostic factors for survival in patients with mucosal malignant melanoma of the sinonasal tract. Patients managed between 1991 and 2008 were assessed retrospectively. The seventh edition Union for International Cancer Control (7th UICC) tumour-node-metastasis classification was used for tumour staging. Kaplan-Meier and log rank tests were used for survival analysis. Twenty-five patients were studied (six were tumour stage three, eight tumour stage four(a) and 11 tumour stage four(b)). Surgery was performed on 23 patients (92 per cent). Fifteen received post-operative radiotherapy. Mean follow up was 31.3 months (range, two to 99 months). Three-year disease-free survival was improved in patients with stage four tumour arising from the nasal fossa, versus other sites, and in those with stage four tumour treated with surgery plus adjuvant radiotherapy, versus other treatments. Patients with melanoma of the nasal cavity have very poor survival rates. Treatment is still based on adequate surgical resection with safe margins. In this study, post-operative radiotherapy improved local control only for stage four tumours.

There is a need for effective "broad spectrum" therapies for metastatic melanoma which would be suitable for all patients. The objectives of Phase Ia/Ib studies were to evaluate the safety, pharmacokinetics, dosimetry, and antitumor activity of (188)Re-6D2, a 188-Rhenium-labeled antibody to melanin. Stage IIIC/IV metastatic melanoma (MM) patients who failed standard therapies were enrolled in both studies. In Phase Ia, 10 mCi (188)Re-6D2 were given while unlabeled antibody preload was escalated. In Phase Ib, the dose of (188)Re-6D2 was escalated to 54 mCi. SPECT/CT revealed (188)Re-6D2 uptake in melanoma metastases. The mean effective half-life of (188)Re-6D2 was 12.4 h. Transient HAMA was observed in 9 patients. Six patients met the RECIST criteria for stable disease at 6 weeks. Two patients had durable disease stabilization for 14 weeks and one for 22 weeks. Median overall survival was 13 months with no dose-limiting toxicities. The data demonstrate that (188)Re-6D2 was well tolerated, localized in melanoma metastases, and had antitumor activity, thus warranting its further investigation in patients with metastatic melanoma.

Melanoma Stem Cells and Metastasis: Mimicking Hematopoietic Cell Trafficking?

PubMed Central

Lee, Nayoung; Barthel, Steven R.; Schatton, Tobias

2014-01-01

Malignant melanoma is a highly metastatic cancer that bears responsibility for the majority of skin cancer-related deaths. Amidst the research efforts to better understand melanoma progression, there has been increasing evidence that hints at a role for a subpopulation of virulent cancer cells, termed malignant melanoma stem or initiating cells (MMICs), in metastasis formation. MMICs are characterized by their preferential ability to initiate and propagate tumor growth and their selective capacity for self-renewal and differentiation into less tumorigenic melanoma cells. The frequency of MMICs has been shown to correlate with poor clinical prognosis in melanoma. Additionally, MMICs are enriched among circulating tumor cells (CTCs) in the peripheral blood of cancer patients, suggesting that MMICs may be a critical player in the metastatic cascade. Although these links exist between MMICs and metastatic disease, the mechanisms by which MMICs may advance metastatic progression are only beginning to be elucidated. Recent studies have shown that MMICs express molecules critical for hematopoietic cell maintenance and trafficking, providing a possible explanation for how circulating MMICs could drive melanoma dissemination. We therefore propose that MMICs might fuel melanoma metastasis by exploiting homing mechanisms commonly utilized by hematopoietic cells. Here we review the biological properties of MMICs and the existing literature on their metastatic potential. We will discuss possible mechanisms by which MMICs might initiate metastases in the context of established knowledge of cancer stem cells (CSCs) in other cancers and of hematopoietic homing molecules, with a particular focus on selectins, integrins, chemokines, and chemokine receptors known to be expressed by melanoma cells. Biological understanding of how these molecules might be utilized by MMICs to propel the metastatic cascade could critically impact the development of more effective therapies for advanced

Preexisting MEK1 Exon 3 Mutations in V600E/KBRAF Melanomas Do Not Confer Resistance to BRAF Inhibitors

BRAF inhibitors (BRAFi) induce antitumor responses in nearly 60% of patients with advanced V600E/KBRAF melanomas. Somatic activating MEK1 mutations are thought to be rare in melanomas, but their potential concurrence with V600E/KBRAF may be selected for by BRAFi. We sequenced MEK1/2 exon 3 in melanomas at baseline and upon disease progression. Of 31 baseline V600E/KBRAF melanomas, 5 (16%) carried concurrent somatic BRAF/MEK1 activating mutations. Three of 5 patients with BRAF/MEK1 double-mutant baseline melanomas showed objective tumor responses, consistent with the overall 60% frequency. No MEK1 mutation was found in disease progression melanomas, except when it was already identified at baseline. MEK1-mutant expression in V600E/KBRAF melanoma cell lines resulted in no significant alterations in p-ERK1/2 levels or growth-inhibitory sensitivities to BRAFi, MEK1/2 inhibitor (MEKi), or their combination. Thus, activating MEK1 exon 3 mutations identified herein and concurrent with V600E/KBRAF do not cause BRAFi resistance in melanoma. SIGNIFICANCE As BRAF inhibitors gain widespread use for treatment of advanced melanoma, bio-markers for drug sensitivity or resistance are urgently needed. We identify here concurrent activating mutations in BRAF and MEK1 in melanomas and show that the presence of a downstream mutation in MEK1 does not necessarily make BRAF–mutant melanomas resistant to BRAF inhibitors.

Several genetic alterations have been demonstrated to contribute to the development and progression of melanoma. In this study, we further investigated the impact of key-regulator genes in susceptibility and pathogenesis of such a disease. A large series (N = 846) of sporadic and familial cases originating from South Italy was screened for germline mutations in p16(CDKN2A), BRCA2, and MC1R genes by DHPLC analysis and automated DNA sequencing. Paired primary melanomas and lymph node metastases from same patients (N = 35) as well as melanoma cell lines (N = 18) were analyzed for somatic mutations in NRAS, BRAF, and p16(CDKN2A) genes. For melanoma susceptibility, investigations at germline level indicated that p16(CDKN2A) was exclusively mutated in 16/545 (2.9%) non-Sardinian patients, whereas BRCA2 germline mutations were observed in 4/91 (4.4%) patients from North Sardinia only. Two MC1R germline variants, Arg151Cys and Asp294His, were significantly associated with melanoma in Sardinia. Regarding genetic events involved in melanoma pathogenesis at somatic level, mutually-exclusive mutations of NRAS and BRAF genes were observed at quite same rate (about two thirds) in cultured and in vivo melanomas (either primary or metastatic lesions). Conversely, p16(CDKN2A) gene alterations were observed at increased rates moving from primary to metastatic melanomas and melanoma cell lines. Activation of the ERK gene product was demonstrated to be consistently induced by a combination of molecular alterations (NRAS/BRAF mutations and p16(CDKN2A) silencing). Our findings further clarified that: a) mutation prevalence in melanoma susceptibility genes may vary within each specific geographical area; b) multiple molecular events are accumulating during melanomagenesis.

Vemurafenib: in unresectable or metastatic melanoma.

PubMed

Keating, Gillian M

Vemurafenib is a first-in-class, small molecule BRAFV600E inhibitor. It is indicated in the US for the treatment of patients with unresectable or metastatic melanoma with the BRAFV600E mutation, and in the EU as monotherapy in adults with BRAFV600 mutation-positive unresectable or metastatic melanoma. Oral vemurafenib improved overall survival (OS) [co-primary endpoint] in patients with unresectable, previously untreated, BRAFV600E mutation-positive, stage IIIC or IV melanoma, according to the results of a randomized, open-label, multicenter, phase III trial (BRIM-3). With vemurafenib versus dacarbazine, the risk of death was significantly reduced by 63% in the interim OS analysis, and by 56%, 38%, and 30% in subsequent updated OS analyses. The median OS duration was 13.6 months in vemurafenib recipients and 9.7 months in dacarbazine recipients in the most recent OS analysis. In the phase III trial, progression-free survival (PFS) [co-primary endpoint] was also significantly improved in vemurafenib versus dacarbazine recipients (median PFS of 5.3 vs 1.6 months), with a significant reduction in the risk of death or disease progression of 74% in the final PFS analysis. Vemurafenib was also associated with a high overall response rate in patients with previously treated, BRAFV600 mutation-positive, stage IV melanoma, according to the results of a noncomparative, multicenter, phase II trial. Patients had received at least one prior systemic treatment for advanced disease (excluding BRAF inhibitors other than sorafenib or MEK inhibitors). The overall response rate (primary endpoint) was 53% (complete response rate of 6% and partial response rate of 47%), with a median duration of response of 6.7 months, and a median OS duration of 15.9 months. Oral vemurafenib was generally well tolerated in patients with metastatic melanoma, with cutaneous adverse events among the most commonly occurring adverse events. Cutaneous squamous cell carcinoma and/or keratoacanthoma were

Sentinel lymph node biopsy (SLNB) is indicated for the staging of clinically lymph node-negative melanoma of intermediate thickness, but its use is controversial in patients with thick melanoma. From 2002 to 2012, patients with melanoma measuring ≥4 mm in thickness were evaluated at a single institution. Associations between survival and clinicopathologic characteristics were explored. Of 571 patients with melanomas measuring ≥4 mm in thickness and no distant metastases, the median age was 66 years and 401 patients (70.2%) were male. The median Breslow thickness was 6.2 mm; the predominant subtype was nodular (45.4%). SLNB was performed in 412 patients (72%) whereas 46 patients (8.1%) presented with clinically lymph node-positive disease and 113 patients (20%) did not undergo SLNB. A positive SLN was found in 161 of 412 patients (39.1%). For SLNB performed at the study institution, 14 patients with a negative SLNB developed disease recurrence in the mapped lymph node basin (false-negative rate, 12.3%). The median disease-specific survival (DSS), overall survival (OS), and recurrence-free survival (RFS) for the entire cohort were 62.1 months, 42.5 months, and 21.2 months, respectively. The DSS and OS for patients with a negative SLNB were 82.4 months and 53.4 months, respectively; 41.2 months and 34.7 months, respectively, for patients with positive SLNB; and 26.8 months and 22 months, respectively, for patients with clinically lymph node-positive disease (P<.0001). The median RFS was 32.4 months for patients who were SLNB negative, 14.3 months for patients who were SLNB positive, and 6.8 months for patients with clinically lymph node-positive disease (P<.0001). With an acceptably low false-negative rate, patients with thick melanoma and a negative SLNB appear to have significantly prolonged RFS, DSS, and OS compared with those with a positive SLNB. Therefore, SLNB should be considered as indicated for patients with thick, clinically lymph node-negative melanoma

Background Metastatic melanoma is an untreatable cancer lacking reliable and non-invasive markers of disease progression. Exosomes are small vesicles secreted by normal as well as tumor cells. Human tumor-derived exosomes are involved in malignant progression and we evaluated the presence of exosomes in plasma of melanoma patients as a potential tool for cancer screening and follow-up. Methodology/Principal Findings We designed an in-house sandwich ELISA (Exotest) to capture and quantify exosomes in plasma based on expression of housekeeping proteins (CD63 and Rab-5b) and a tumor-associated marker (caveolin-1). Western blot and flow cytometry analysis of exosomes were used to confirm the Exotest-based findings. The Exotest allowed sensitive detection and quantification of exosomes purified from human tumor cell culture supernatants and plasma from SCID mice engrafted with human melanoma. Plasma levels of exosomes in melanoma-engrafted SCID mice correlated to tumor size. We evaluated the levels of plasma exosomes expressing CD63 and caveolin-1 in melanoma patients (n = 90) and healthy donors (n = 58). Consistently, plasma exosomes expressing CD63 (504±315) or caveolin-1 (619±310) were significantly increased in melanoma patients as compared to healthy donors (223±125 and 228±102, respectively). While the Exotest for CD63+ plasma exosomes had limited sensitivity (43%) the Exotest for detection of caveolin-1+ plasma exosomes showed a higher sensitivity (68%). Moreover, caveolin-1+ plasma exosomes were significantly increased with respect to CD63+ exosomes in the patients group. Conclusions/Significance We describe a new non-invasive assay allowing detection and quantification of human exosomes in plasma of melanoma patients. Our results suggest that the Exotest for detection of plasma exosomes carrying tumor-associated antigens may represent a novel tool for clinical management of cancer patients. PMID:19381331

Metastatic melanoma is an untreatable cancer lacking reliable and non-invasive markers of disease progression. Exosomes are small vesicles secreted by normal as well as tumor cells. Human tumor-derived exosomes are involved in malignant progression and we evaluated the presence of exosomes in plasma of melanoma patients as a potential tool for cancer screening and follow-up. We designed an in-house sandwich ELISA (Exotest) to capture and quantify exosomes in plasma based on expression of housekeeping proteins (CD63 and Rab-5b) and a tumor-associated marker (caveolin-1). Western blot and flow cytometry analysis of exosomes were used to confirm the Exotest-based findings. The Exotest allowed sensitive detection and quantification of exosomes purified from human tumor cell culture supernatants and plasma from SCID mice engrafted with human melanoma. Plasma levels of exosomes in melanoma-engrafted SCID mice correlated to tumor size. We evaluated the levels of plasma exosomes expressing CD63 and caveolin-1 in melanoma patients (n = 90) and healthy donors (n = 58). Consistently, plasma exosomes expressing CD63 (504+/-315) or caveolin-1 (619+/-310) were significantly increased in melanoma patients as compared to healthy donors (223+/-125 and 228+/-102, respectively).

Malignant melanoma is considered the most lethal skin cancer if not detected and treated at its early stages. About 10% of melanoma patients report a family history of melanoma; however, individuals with features of true hereditary melanoma (i.e. unilateral lineage, multi-generational, multiple primary lesions, and early onset of disease) are in fact quite rare. Although many new loci have been implicated in hereditary melanoma, CDKN2A mutations remain the most common. Familial melanoma in the presence of multiple atypical nevi should raise suspicion for a germline CDKN2A mutation. Such patients have a high risk of developing multiple primary melanomas and internal organ malignancies especially pancreatic cancer; thus, a multidisciplinary approach is necessary in many cases. The value of dermoscopy examination and total body photography performed at regular intervals has been suggested by a number of studies, and should therefore be considered for these patients and their first degree relatives. In addition, genetic counseling with the possibility of testing can be a valuable adjunct for familial melanoma patients. But, this must be performed with care and only by qualified individuals trained in cancer risk analysis. PMID:26892650

Purpose: To determine prognostic factors that allow the selection of melanoma patients with advanced intra- and extracerebral metastatic disease for palliative whole-brain radiation therapy (WBRT) or best supportive care. Methods and Materials: This was a retrospective study of 87 patients who underwent palliative WBRT between 1988 and 2009 for progressive or multiple cerebral metastases at presentation. Uni- and multivariate analysis took into account the following patient- and tumor-associated factors: gender and age, Karnofsky performance status (KPS), neurologic symptoms, serum lactate dehydrogenase (LDH) level, number of intracranial metastases, previous resection or stereotactic radiosurgery of brain metastases, number of extracranial metastasis sites,more » and local recurrences as well as regional lymph node metastases at the time of WBRT. Results: In univariate analysis, KPS, LDH, number of intracranial metastases, and neurologic symptoms had a significant influence on overall survival. In multivariate survival analysis, KPS and LDH remained as significant prognostic factors, with hazard ratios of 3.3 (95% confidence interval [CI] 1.6-6.5) and 2.8 (95% CI 1.6-4.9), respectively. Patients with KPS ≥70 and LDH ≤240 U/L had a median survival of 191 days; patients with KPS ≥70 and LDH >240 U/L, 96 days; patients with KPS <70 and LDH ≤240 U/L, 47 days; and patients with KPS <70 and LDH >240 U/L, only 34 days. Conclusions: Karnofsky performance status and serum LDH values indicate whether patients with advanced intra- and extracranial tumor manifestations are candidates for palliative WBRT or best supportive care.« less

Purpose High-dose radiotherapy can cause contracture of the anophthalmic socket, but the incidence of this complication in patients with enucleation for uveal melanoma has not previously been reported. We reviewed the surgical management and outcomes in terms of successful prosthesis wear in patients with severe contracture of the anophthalmic socket treated with high-dose radiotherapy for high-risk uveal melanoma and estimated the relative risk of this complication. Methods The medical records of all consecutive patients enrolled in a prospective uveal-melanoma tissue-banking protocol at our institution who underwent enucleation between January 2003 and December 2010 were reviewed. Patients who underwent adjuvant radiotherapy of the enucleated socket were further studied. Results Of the 68 patients enrolled in the prospective tissue banking protocol, 12 had high-risk histologic features (e.g., extrascleral spread or vortex vein invasion) and were treated with 60 Gy of external-beam radiotherapy after enucleation. Five of these patients (41.7%) experienced severe socket contracture precluding prosthesis wear. The median time to onset of contracture following completion of radiotherapy was 20 months. Three patients underwent surgery, which entailed scar tissue release, oral mucous membrane grafting, and socket reconstruction; 2 patients declined surgery. All 3 patients who had surgery experienced significant improvement of socket contracture that enabled patients to wear a prosthesis again. Conclusion High-dose radiotherapy after enucleation in patients with uveal melanoma caused severe socket contracture and inability to wear a prosthesis in approximately 40% of patients. Surgical repair of the contracted socket using oral mucous membrane grafting can allow resumption of prosthesis wear. PMID:22581085

Melanoma is a serious and deadly form of skin cancer. However, patients' chances of survival and recovery are considerably increased when it is diagnosed and treated in its early stages. In this study, trace element concentrations in serum samples from patients with melanoma were measured using PIXE (Proton Induced X-ray Emission) and HR-ICPMS (High-Resolution Inductively Coupled Plasma Mass Spectrometry), with the purpose of correlating these concentrations with the disease. Blood samples from 30 melanoma patients and 116 healthy donors were collected at São Paulo Hospital (protocol CEP 1036/08 UNIFESP). Relevant clinical information on the patients has also been included in the statistical analysis. Analysis of the control group showed different P and Mg concentrations in individuals above and below 40 years of age. P, S, Ca, Cu and Zn concentrations in healthy individuals differed according to gender, highlighting the necessity to include age and gender variables in the case-control analysis. There were also differences in K, S, Ca and Se concentrations between the control and melanoma groups.

Approximately 20% of melanoma patients harbor metastases in non-sentinel nodes (NSNs) after a positive sentinel node biopsy (SNB), and recent evidence questions the therapeutic benefit of completion lymph node dissection (CLND). We built a nomogram for prediction of NSN status in melanoma patients with positive SNB. Data on anthropometric and clinicopathological features of patients with cutaneous melanoma who underwent CLND after a positive SNB were collected from nine Italian centers. Multivariate logistic regression was utilized to identify predictors of NSN status in a training set, while model efficiency was validated in a validation set. Data were available for 1220 patients treated from 2000 through 2016. In the training set (n = 810), the risk of NSN involvement was higher when (1) the primary melanoma is thicker or (2) sited in the trunk/head and neck; (3) fewer nodes are excised and (4) more nodes are involved; and (5) the lymph node metastasis is larger or (6) is deeply located. The model showed high discrimination (area under the receiver operating characteristic curve 0.74, 95% confidence interval [CI] 0.70-0.79) and calibration (Brier score 0.16, 95% CI 0.15-0.17) performance in the validation set (n = 410). The nomogram including these six clinicopathological variables performed significantly better than five other previously published models in terms of both discrimination and calibration. Our nomogram could be useful for follow-up personalization in clinical practice, and for patient risk stratification while conducting clinical trials or analyzing their results.

Advanced melanoma patients have an extremely poor long term prognosis and are in strong need of new therapies. The recently developed targeted therapies have resulted in a marked antitumor effect, but most responses are partial and some degree of toxicity remain the major concerns. Dendritic cells play a key role in the activation of the immune system and have been typically used as ex vivo antigen-loaded cell drugs for cancer immunotherapy. Another approach consists in intratumoral injection of unloaded DCs that can exploit the uptake of a wider array of tumor-specific and individual unique antigens. However, intratumoral immunization requires DCs endowed at the same time with properties typically belonging to both immature and mature DCs (i.e. antigen uptake and T cell priming). DCs generated in presence of interferon-alpha (IFN-DCs), due to their features of partially mature DCs, capable of efficiently up-taking, processing and cross-presenting antigens to T cells, could successfully carry out this task. Combining intratumoral immunization with tumor-destructing therapies can induce antigen release in situ, facilitating the injected DCs in triggering an antitumor immune response. We tested in a phase I clinical study in advanced melanoma a chemo-immunotherapy approach based on unloaded IFN-DCs injected intratumorally one day after administration of dacarbazine. Primary endpoint of the study was treatment safety and tolerability. Secondary endpoints were immune and clinical responses of patients. Six patients were enrolled, and only three completed the treatment. The chemo-immunotherapy was well tolerated with no major side effects. Three patients showed temporary disease stabilization and two of them showed induction of T cells specific for tyrosinase, NY-ESO-1 and gp100. Of interest, one patient showing a remarkable long-term disease stabilization kept showing presence of tyrosinase specific T cells in PBMC and high infiltration of memory T cells in the tumor

Despite unprecedented efficacy across multiple tumor types, immune checkpoint inhibitor therapy is associated with a unique and wide spectrum of immune-related adverse events (irAEs), including neurologic events ranging from mild headache to potentially life-threatening encephalitis. Here, we summarize neurologic irAEs associated with nivolumab and ipilimumab melanoma treatment, present cases of treatment-related encephalitis, and provide practical guidance on diagnosis and management. We searched a Global Pharmacovigilance and Epidemiology database for neurologic irAEs reported over an 8-year period in patients with advanced melanoma receiving nivolumab with or without ipilimumab from 12 studies sponsored by Bristol-Myers Squibb. Serious neurologic irAEs were reviewed, and relationship to nivolumab or ipilimumab was assigned. In our search of 3,763 patients, 35 patients (0.93%) presented with 43 serious neurologic irAEs, including neuropathy ( n  = 22), noninfective meningitis ( n  = 5), encephalitis ( n  = 6), neuromuscular disorders ( n  = 3), and nonspecific adverse events ( n  = 7). Study drug was discontinued ( n  = 20), interrupted ( n  = 8), or unchanged ( n  = 7). Most neurologic irAEs resolved (26/35 patients; 75%).

Melanoma incidence is increasing. We evaluated risk of melanoma death after diagnosis of non-melanoma skin cancer (NMSC). We followed 77,288 female American nurses from the Nurses' Health Study from 1986 to 2012. We used Cox proportional hazards models to determine the hazard ratio (HR) of lethal and non-lethal melanoma diagnosis and melanoma death, according to personal NMSC history. Among melanoma cases, we examined the HR of melanoma death and the odds ratio (OR) of melanoma with a Breslow thickness ≥0.8 mm or Clark's levels of IV and V according to history of NMSC. We documented 930 melanoma cases without NMSC history and 615 melanoma cases with NMSC history over 1.8 million person-years. The multivariate-adjusted HR (95% confidence interval) of melanoma death associated with personal history of NMSC was 2.89 (1.85-4.50). Women with history of NMSC were more likely to develop non-lethal melanoma than lethal melanoma (HR (95% CI): 2.31 (2.05-2.60) vs. 1.74 (1.05-2.87)). Among melanoma cases, women with history of NMSC had a non-significant decreased risk of melanoma deaths (0.87 (0.55-1.37)), Breslow thickness ≥0.8 mm (0.85 (0.59-1.21)) and Clark's levels IV and V (0.81(0.52-1.24)). Women with NMSC history were less likely to be diagnosed with a lethal melanoma than a non-lethal melanoma, but overall rate of melanoma diagnosis was increased in both subtypes, leading to the increased risk of melanoma death. Our findings suggest the continued need for dermatologic screening for patients after NMSC diagnosis, given increased melanoma risk. Early detection among NMSC patients may decrease deaths from melanoma. © 2017 UICC.

Background Malignant melanoma is the most aggressive and deadly form of skin cancer. Dacarbazine (DTIC) has been the approved first-line treatment for metastatic melanoma in routine clinical practice. However, response rates with single-agent DTIC are low. The objective of this study was to compare the efficacy and safety of DTIC with or without placebo and DTIC-based combination therapies in patients with advanced metastatic melanoma. Methods We searched from electronic databases such as The Cochrane Library, MEDLINE, EBSCO, EMBASE, Ovid, CNKI, and CBMDisc from 2003 to 2013. The primary outcome measures were overall response and 1-year survival, and the secondary outcome measurements were adverse events. Results Nine randomized controlled trials (RCTs) involving 2,481 patients were included in the meta-analysis. DTIC-based combination therapies was superior to DTIC alone in overall response (combined risk ratio [RR]  = 1.60, 95% confidence interval [CI]: 1.27–2.01) and 1-year survival (combined RR = 1.26, 95% CI: 1.14–1.39). Patients with DTIC-based combination therapies had higher incidence of adverse events including nausea (combined RR = 1.23, 95% CI: 1.10–1.36), vomiting (combined RR = 1.73, 95% CI: 1.41–2.12) and neutropenia (combined RR = 1.75, 95% CI: 1.42–2.16) compared to the group for DTIC alone. Conclusion These data suggested that DTIC-based combination therapies could moderately improve the overall response and the 1-year survival but increased the incidence of adverse events. Further large-scale, high-quality, placebo-controlled, double-blind trials are needed to confirm this conclusion. PMID:25502446

Fourteen variables were tested for their prognostic usefulness in 203 patients with clinical Stage I melanoma and primary tumor 0.76-169 mm thick. Only two variables, primary tumor location and level of invasion, were useful in predicting death from melanoma for these patients. Of the 12 deaths from melanoma, 11 occurred in patients with primary tumors located on the upper back, posterior arm, posterior neck, and posterior scalp (=BANS). There has been only one death from melanoma in 136 patients with melanoma located at other sites (11/67 vs 1/136, p less than 0.0001 Fisher's Exact Test). Of the 67 BANS patients, 51 had level II or level III lesions and five (10%0 died of melanoma. This compared with six deaths from melanoma in 16 patients (37.5%) with level IV BANS lesions (5/51 vs 6/16, p = 0.01 Fisher's Exact Test). The relatively high incidence of both melanoma deaths and regional node metastases for the BANS group merits consideration for testing the efficacy of elective regional node dissection for these patients.

The peripheral blood lymphocyte-to-monocyte ratio (LMR) has been associated with prognosis in many malignancies including metastatic melanoma. However, it has not been studied in patients treated with immune checkpoint inhibitors. In this study, we analyzed the baseline LMR with progression-free survival (PFS) and overall survival (OS) in metastatic melanoma patients treated with pembrolizumab. A total of 133 patients with metastatic melanoma treated with pembrolizumab were included in this retrospective study. LMR was calculated from pretherapy peripheral blood counts and the optimal cutoff value was determined by a receiver operator characteristic curve. PFS and OS were evaluated using the Kaplan-Meier method and multivariate Cox proportional hazard modeling. Patients with an LMR of at least 1.7 showed improved PFS (hazard ratio=0.55; 95% confidence interval: 0.34-0.92; P=0.024) and OS (hazard ratio=0.29; 95% confidence interval: 0.15-0.59; P=0.0007). The baseline LMR is associated with PFS and OS in metastatic melanoma patients treated with pembrolizumab, and could represent a convenient and cost-effective prognostic biomarker. Validation of these findings in an independent cohort is needed.

The mortality of cutaneous melanoma has not declined over the past 50 years. The only interventions that can reduce mortality are primary prevention and early diagnosis, and the dermoscopic evaluation is essential to achieve this. Dermoscopy identifies characteristics of melanoma that would go unnoticed to the naked eye. The aim of this paper is to report the most frequent dermoscopic findings in patients diagnosed with in situ and invasive melanoma. An observational and retrospective study of contact dermoscopy was performed using LED DermliteTM and camera DermliteTM dermoscope. The findings evaluated were: asymmetry in two axes, association of colours, lack of pigment, irregular points, atypical network, pseudopods, blue veil, ulceration, and peri-lesional pink ring. These dermoscopic findings were compared with the histological diagnosis. The study included 65 patients with cutaneous melanoma; 10 in situ, and 55 invasive. The mean Breslow in invasive melanoma was 3 mm. Most patients (35) had localization in extremities. In all patients, the most frequent dermoscopic finding was asymmetry in two axes, followed by association of two or more colours; in melanoma in situ, asymmetry was the most frequent, followed by atypical-irregular points. In invasive melanoma asymmetry in two axes, the association of two or more colours, and pseudopods, were the most frequent findings. Asymmetry in two axes is the most common dermoscopic finding in in situ and invasive melanoma. The presence of two or more colours in a pigmented lesion should be suspected in an invasive melanoma.

A phase 2 study of vatalanib (PTK787/ZK222584) an oral tyrosine kinase inhibitor of VEGFR 1, 2 and 3 was undertaken in patients with metastatic melanoma. Adults with pathologically confirmed metastatic melanoma, WHO Performance status 0-2, and adequate haematological, hepatic and renal function, were treated with vatalanib until disease progression. The trial used Fleming's single stage design. Tumour control rate (CR+PR+SD) was 35% at 16 weeks, with objective response seen in only 1 patient. Median progression-free survival was 1.8 months (95% CI 1.8-3.7 months) and median overall survival was 6.5 months (95% CI 3.9-10.2 months). Vatalanib stabilised disease in a proportion of patients, although overall survival was disappointing. Copyright © 2010 Elsevier Ltd. All rights reserved.

Melanoma is an aggressive cancer with highly metastatic ability. We propose cofilin-1, a key protein in the regulation of actin dynamics and migration, as a prognostic marker. We determined cofilin-1 levels in a retrospective cohort of patients with melanomas and benign lesions of melanocytes (nevi) by immunohistochemistry. Higher cofilin-1 levels were found in malignant melanoma (MM) with Breslow Index (BI)>2 vs MM with BI<2, melanoma in situ (MIS) and nevi and also in MM with metastasis vs MM without detected metastasis. Kaplan-Meier survival curves were performed, clustering patients according to either the type of melanocytic lesions or cofilin-1 level. Survival curves demonstrated worse prognosis of patients with high vs low cofilin-1 levels. TCGA database analysis of melanoma also showed low survival in patients with upregulated cofilin-1 mRNA vs patients without alteration in CFL1 mRNA expression. As cofilin-1 has a dual function depending on its intracellular localization, we evaluated nuclear and cytoplasmic levels of cofilin-1 in melanoma and nevi samples by immunofluorescence. MM with high Breslow index and metastatic cells not only presented cytoplasmic cofilin-1, but also showed this protein at the nucleus. An increase in nuclear/cytoplasmic cofilin-1 mean fluorescence ratio was observed in MM with BI>2 vs MM with BI<2, MIS and nevi. In conclusion, an association of cofilin-1 levels with malignant features and an inverse correlation with survival were demonstrated. Moreover, this study suggests that not only the higher levels of cofilin-1, but also its nuclear localization can be proposed as marker of worse outcome of patients with melanoma. PMID:29844875

Kaplan-Meier survival curves were performed, clustering patients according to either the type of melanocytic lesions or cofilin-1 level. Survival curves demonstrated worse prognosis of patients with high vs low cofilin-1 levels. TCGA database analysis of melanoma also showed low survival in patients with upregulated cofilin-1 mRNA vs patients without alteration in CFL1 mRNA expression. As cofilin-1 has a dual function depending on its intracellular localization, we evaluated nuclear and cytoplasmic levels of cofilin-1 in melanoma and nevi samples by immunofluorescence. MM with high Breslow index and metastatic cells not only presented cytoplasmic cofilin-1, but also showed this protein at the nucleus. An increase in nuclear/cytoplasmic cofilin-1 mean fluorescence ratio was observed in MM with BI>2 vs MM with BI<2, MIS and nevi. In conclusion, an association of cofilin-1 levels with malignant features and an inverse correlation with survival were demonstrated. Moreover, this study suggests that not only the higher levels of cofilin-1, but also its nuclear localization can be proposed as marker of worse outcome of patients with melanoma.

Metastatic melanoma is an aggressive disease with poor prognosis. Melanoma can potentially involve any organ. In this article, we report on a single-centre experience in emergency surgery for M1c melanoma. Twenty-eight consecutive patients with M1c melanoma underwent surgical exploration due to abdominal emergencies. Pre-operative computed tomography confirmed the diagnosis and the location of the affected site. Pre-operative lactate dehydrogenase serum levels and post-operative histopathology findings were recorded. Intestinal obstruction was the most frequent intraoperative finding (75%). The ileum was most frequently affected (28.6%). Multifocal disease and extra-gastrointestinal tract metastases were present in 25% of cases each. Lactate dehydrogenase serum level was increased in 75% of the patients. Most patients underwent an enterectomy. Curative surgery for stage IV melanoma remains debatable, but surgery for patients presenting with abdominal emergencies appears to improve both survival rate and prognosis. Combined novel therapies and surgical resection is currently being studied with promising results. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Enhancing immune responses with immune-modulatory monoclonal antibodies directed to inhibitory immune receptors is a promising modality in cancer therapy. Clinical efficacy has been demonstrated with antibodies blocking inhibitory immune checkpoints such as cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) or PD-1/PD-L1. Treatment with ipilimumab, a fully human CTLA-4–specific mAb, showed durable clinical efficacy in metastatic melanoma; its mechanism of action is, however, only partially understood. This is a study of 29 patients with advanced cutaneous melanoma treated with ipilimumab. We analyzed peripheral blood mononuclear cells (PBMCs) and matched melanoma metastases from 15 patients responding and 14 not responding to ipilimumab by multicolor flow cytometry, antibody-dependent cell-mediated cytotoxicity (ADCC) assay, and immunohistochemistry. PBMCs and matched tumor biopsies were collected 24 h before (i.e., baseline) and up to 4 wk after ipilimumab. Our findings show, to our knowledge for the first time, that ipilimumab can engage ex vivo FcγRIIIA (CD16)-expressing, nonclassical monocytes resulting in ADCC-mediated lysis of regulatory T cells (Tregs). In contrast, classical CD14++CD16− monocytes are unable to do so. Moreover, we show that patients responding to ipilimumab display significantly higher baseline peripheral frequencies of nonclassical monocytes compared with nonresponder patients. In the tumor microenvironment, responders have higher CD68+/CD163+ macrophage ratios at baseline and show decreased Treg infiltration after treatment. Together, our results suggest that anti–CTLA-4 therapy may target Tregs in vivo. Larger translational studies are, however, warranted to substantiate this mechanism of action of ipilimumab in patients. PMID:25918390

The incidence of cutaneous malignant melanoma is rapidly increasing in Denmark like in other Northern and Western European countries. Our objective was to investigate the characteristics of current patients suffering from cutaneous malignant melanoma. We evaluated patient and tumour characteristics in a cross-sectional study based on data from the Danish Melanoma Register. We included all patients diagnosed with cutaneous malignant melanoma in Healthcare Region Zealand in 2012 and 2013. We identified 520 patients with invasive cutaneous malignant melanoma. More females than males suffered from cutaneous malignant melanoma. Furthermore, females were younger than males, and the anatomical distribution of malignant melanoma varied between the genders. Outcome of sentinel lymph node biopsy was associated with tumour thickness. When comparing findings in our study with earlier Danish studies, we see a trend towards an increase in age at diagnosis. Furthermore, tumour thickness is decreasing and the topical distribution of cutaneous malignant melanoma in females changes towards a male pattern. none. The study has been approved by the Danish National Data Protection Agency.

A limited number of studies have been performed so far on the polymorphism in the transmembrane region (exon 5) of the major histocompatibility complex class I chain-related gene A (MICA) in patients with melanoma. However, the influence of MICA polymorphism in extracellular domains (exons 2, 3, and 4) has not been investigated on melanoma disease. This study aims to characterize the influence of extracellular MICA polymorphism, and its previously described linkage disequilibrium with HLA-B locus, on patients with cutaneous melanoma from southeastern Spain. For this purpose, MICA and HLA-B genotyping was performed in 233 patients and 200 ethnically matched controls by luminex technology. Patients were classified according to the presence of methionine or valine at codon 129 of MICA gene. We found a high frequency of MICA(*)009 in melanoma patients compared with controls (P = 0.002, Pc = 0.03). Our results also showed an association between MICA(*)009 and HLA-B(*)51 alleles in both patients and controls. This association was stronger in patients than controls (P = 0.015). However, a multivariate logistic regression model showed that neither MICA(*)009 nor the combination MICA(*)009/HLA-B(*)51 was associated with melanoma susceptibility. No relationship was observed between MICA-129 dimorphism and melanoma nor when MICA polymorphism was evaluated according to clinical findings at diagnosis.

Incidence rates of melanoma, generated by cancer registries (CRs), are susceptible to reporting inconsistencies due to increasing decentralisation of diagnosis. We therefore independently assessed the burden of melanoma in Austria. We collected histopathological reports on melanoma of all patients diagnosed in Austria in 2011. Demographic and clinical characteristics, histopathological tumour stages were assessed. Their regional distributions and incidence rates were analysed and compared with data of national and international CRs. A total of 5246 patients were diagnosed with 1951 in-situ and 3295 invasive melanomas in Austria in 2011 (population 8.4 million). Age, sex and anatomic distribution corresponded to findings in other European countries, however, the incidence of 25/100,000 (world age-standardised rate) for invasive melanomas was two-fold higher than published by the Austrian CR (12/100,000). Varying frequencies in diagnosing thin melanomas (≤1 mm; n = 4415) accounted exclusively for significant regional disparities, while advanced tumours (>1 mm; n = 761) were evenly distributed. Western Austria showed the highest rates (36/100,000). Patients from eastern Austria whose melanomas were diagnosed in laboratories in western Austria (n = 76) showed significantly higher proportions of in-situ lesions (n = 43; 57%) compared to those whose tumours were diagnosed in eastern Austria (n = 4014; in-situ = 1369; 34%) (p < 0.0001). In Austria, the melanoma burden and its potential socio-economic implications are significantly underestimated. Similarities of incidences indicate this could affect other European countries with well-established CRs and compromise international comparability of data. Austrian regional disparities suggest overdiagnosis of thin melanomas due to the variability of pathologists' thresholds for the diagnosis of early stage tumours. Copyright © 2015 The Authors.

OBJECTIVE. To describe the prognostic factors and epidemiological characteristics of cutaneous and mucosal head and neck melanoma and to identify the variables associated with mortality from this disease. MATERIAL AND METHODS. Patients treated for head and neck melanoma in the Oncology Centre of Latvia, Riga during a 10-year period were identified. Records from 124 cases were analyzed in a descriptive, retrospective study. For each patient, information regarding age, sex, tumor anatomic site, as well as ulceration, histological tumor subtypes, Breslow thickness and Clark invasion level was viewed. Disease specific survival rates were calculated. The frequencies of all study variables and their 95% confidence intervals were determined. Kaplan-Meier survival curves were produced to illustrate the survival differences for each variable. RESULTS. The patients' mean age was 67.36 years. The study included 81 females (65.32%) and 43 males (34.67%). The prevalent anatomical site for cutaneous head and neck melanoma was the cheek - 49% (n=55) and the intraocular site for mucosal melanoma (61.5%). A high percentage of thick cutaneous melanoma was detected. In 53 cases (47.3%) out of 112 cutaneous melanoma the tumor ulceration was found. Nodular melanoma subtype was predominating (38%). The incidence of cutaneous melanoma has increased unequally whereas mucosal melanoma of the head and neck is an uncommon cancer and the incidence rates in Latvia during a ten year period are decreasing. CONCLUSION. Female sex, advanced age, facial skin, tumor thickness, nodular subtype and ulceration carried a relevant risk of poor prognosis.

We investigated whether a previous diagnosis of non-melanoma skin cancer among chronic lymphocytic leukemia patients is a predictor of poor outcome. Using the Swedish Cancer Registry, we conducted a population-based study to evaluate the survival patterns among chronic lymphocytic leukemia patients with and without non-melanoma skin cancer. Cox proportional hazards regression models were used and Kaplan-Meier curves were constructed. Of a total of 12,041 chronic lymphocytic leukemia cases identified, 236 cases, including 111 squamous cell cancer, had a prior history of non-melanoma skin cancer. Chronic lymphocytic leukemia patients with a prior history of non-melanoma skin cancer had a 1.29-fold (95% CI 1.10–1.52; p=0.0024) increased risk of dying; and those with a history of squamous cell cancer had a further elevated 1.86-fold (95% CI 1.46–2.36; p<0.0001) risk of dying. Kaplan-Meier plots showed that patients with a history of non-melanoma skin cancer, particularly those with squamous cell cancer, had significantly poorer survival than chronic lymphocytic leukemia patients without non-melanoma skin cancer (p<0.0001; log-rank test). Non-melanoma skin cancer may be a novel clinical predictor of worse chronic lymphocytic leukemia outcome. PMID:19794092

Background Data on survival with mucosal melanoma and on prognostic factors of are scarce. It is still unclear if the disease course allows for mucosal melanoma to be treated as primary cutaneous melanoma or if differences in overall survival patterns require adapted therapeutic approaches. Furthermore, this investigation is the first to present 10-year survival rates for mucosal melanomas of different anatomical localizations. Methodology 116 cases from Sep 10 1984 until Feb 15 2011 retrieved from the Comprehensive Cancer Center and of the Central Register of the German Dermatologic Society databases in Tübingen were included in our analysis. We recorded anatomical location and tumor thickness, and estimated overall survival at 2, 5 and 10 years and the mean overall survival time. Survival times were analyzed with the Kaplan-Meier method. The log-rank test was used to compare survival times by localizations and by T-stages. Principal Findings We found a median overall survival time of 80.9 months, with an overall 2-year survival of 71.7%, 5-year survival of 55.8% and 10-year survival of 38.3%. The 10-year survival rates for patients with T1, T2, T3 or T4 stage tumors were 100.0%, 77.9%, 66.3% and 10.6% respectively. 10-year survival of patients with melanomas of the vulva was 64.5% in comparison to 22.3% of patients with non-vulva mucosal melanomas. Conclusion Survival times differed significantly between patients with melanomas of the vulva compared to the rest (p = 0.0006). It also depends on T-stage at the time of diagnosis (p<0.0001).

Hispanics are given the diagnosis of melanoma at later stages and have reduced survival. We sought to evaluate the effect of Hispanic ethnicity and different health care delivery systems (fee-for-service [FFS] and health maintenance organizations) on melanoma stage at diagnosis and survival. We studied a retrospective cohort of 40,633 patients, with at least 3 years of follow-up, who were given the diagnosis of incident melanoma from 1991 to 2002 and were 65 years or older using data from the Surveillance, Epidemiology, and End Results-Medicare linked database. The analytic sample consisted of 39,962 non-Hispanic whites (NHW) and 671 Hispanics. Logistic regression models examined the roles of the health care delivery system and race/ethnicity in stage at diagnosis and survival. For FFS patients, Hispanics were more likely to be given a diagnosis at an advanced stage (distant vs earlier stages [odds ratio {OR} = 2.07; 95% confidence interval CI = 1.36-3.16]; regional vs earlier stages [OR = 2.31; 95% CI = 1.75-3.03]) compared with NHW. Among Hispanic patients, those enrolled in health maintenance organizations were less likely to be given a diagnosis at later stage (regional vs earlier stages [OR = 0.50; 95% CI = 0.31-0.81]) than FFS patients; however, the earlier stage at diagnosis did not improve survival. For patients with a previous cancer before their melanoma diagnoses, NHW enrolled in health maintenance organizations from 1991 to 2002 were given a diagnosis at earlier stages compared with NHW FFS patients (OR = 0.72; 95% CI = 0.52-0.99); this was not found among Hispanics. These results reflect findings in a Medicare-aged population and it is not clear if they are generalizable to younger patients. Differences in melanoma outcomes among different ethnic groups are, in part, dependent on the health care setting in which patients are enrolled. Copyright 2010 American Academy of Dermatology, Inc.

The use of fine needle biopsy (FNB) for the diagnosis of metastatic melanoma can lead to the early removal and treatment of metastases, reduce the frequency of unnecessary surgery, and facilitate the staging of patients enrolled in clinical trials of adjuvant therapies. In this study, the accuracy of FNB for the diagnosis of metastatic melanoma was investigated. A retrospective cohort study was performed with 2204 consecutive FNBs performed on 1416 patients known or suspected to have metastatic melanoma. Almost three-quarters (1582) of these FNBs were verified by either histopathologic diagnosis following surgical resection or clinical follow-up. FNB for metastatic melanoma was found to have an overall sensitivity of 92.1% and a specificity of 99.2%, with 69 false-negative and 5 false-positive findings identified. The sensitivity of the procedure was found to be influenced by six factors. The use of immunostains, reporting of the specimen by a cytopathologist who had reported >500 cases, lesions located in the skin and subcutis, and patients with ulcerated primary melanomas were factors associated with a significant improvement in the sensitivity of the test. However, FNBs performed in masses located in lymph nodes of the axilla and FNBs that required more than one needle pass to obtain a sample were far more likely to result in false-negative results. FNB is a rapid, accurate, and clinically useful technique for the assessment of disease status in patients with suspected metastatic melanoma.

Malignant melanoma is potentially life-threatening but in most cases curable if detected early. Willingness to pay (WTP) is a preference-based construct that reflects burden of disease by assessment of the monetary value for a hypothetical cure from disease. Since WTP (directly as total amount of money) has not been assessed so far in patients with low risk melanoma, it was interesting to gain insights in this patient population and then, in a second step, compare it directly with the WTP of their treating dermato-oncologists. WTP was assessed in 125 patients with low-risk melanoma and additionally in 105 treating physicians, asking for the one-time and continuous payments they would be willing to make for a sustainable cure, both as absolute sums and as percentages of monthly income. The median WTP based on one-time payment was €10,000 for patients and €100,000 for physicians; relative numbers were 100% versus 300% of monthly income. For continuous monthly payments, WTP was €500 for patients and €1000 for physicians, relative numbers 25% and 50% of income, respectively. Even after controlling for income differences, there was a significantly higher WTP in physicians for all four questions. Compared to patients with chronic skin diseases such as vitiligo, rosacea, atopic eczema and psoriasis, patients with low-risk melanoma showed a significantly higher WTP. Our data suggest that there is a relevant burden of disease even in patients with low-risk tumors. Higher WTP of physicians underlines the prevalence of differences in disease perception.

Non-melanoma skin cancer (NMSC) is the most common malignancy in humans. Targeted therapy with monoclonal antibody cetuximab is an option in case of advanced tumor or metastasis. We present and update of the use of cetuximab in NMSC searching PUBMED 2011-2017. The monoclonal antibody cetuximab against epidermal growth factor receptor (EGFR) has been investigated for its use in NMSC during the years 2011 to 2017 by a PUBMED research using the following items: "Non-melanoma skin cancer AND cetuximab," "cutaneous squamous cell carcinoma AND cetuximab," and "basal cell carcinoma AND cetuximab", and "cetuximab AND skin toxicity". Available data were analyzed including case reports. Current evidence of cetuximab efficacy in NMSC was mainly obtained in cutaneous SCC and to a lesser extend in BCC. Response rates vary for neoadjuvant, adjuvant, mono- and combined therapy with cetuximab. Management of cutaneous toxicities is necessary. Guidelines are available. Cetuximab is an option for recurrent or advanced NMSC of the skin. It seems to be justified particularly in very high-risk tumors. There is a need for phase III trials.

Uveal melanoma: relatively rare but deadly cancer

PubMed Central

Kaliki, S; Shields, C L

2017-01-01

Although it is a relatively rare disease, primarily found in the Caucasian population, uveal melanoma is the most common primary intraocular tumor in adults with a mean age-adjusted incidence of 5.1 cases per million per year. Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). The host susceptibility factors for uveal melanoma include fair skin, light eye color, inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, and BRCA1-associated protein 1 mutation. Currently, the most widely used first-line treatment options for this malignancy are resection, radiation therapy, and enucleation. There are two main types of radiation therapy: plaque brachytherapy (iodine-125, ruthenium-106, or palladium-103, or cobalt-60) and teletherapy (proton beam, helium ion, or stereotactic radiosurgery using cyber knife, gamma knife, or linear accelerator). The alternative to radiation is enucleation. Although these therapies achieve satisfactory local disease control, long-term survival rate for patients with uveal melanoma remains guarded, with risk for liver metastasis. There have been advances in early diagnosis over the past few years, and with the hope survival rates could improve as smaller tumors are treated. As in many other cancer indications, both early detection and early treatment could be critical for a positive long-term survival outcome in uveal melanoma. These observations call attention to an unmet medical need for the early treatment of small melanocytic lesions or small melanomas in the eye to achieve local disease control and vision preservation with the possibility to prevent metastases and improve overall patient survival.

Although nevus count is an established risk factor for melanoma, relationships between nevus number and patient and tumor characteristics have not been well studied and the influence of nevus count on melanoma-specific survival is equivocal. Using data from the Genes, Environment, and Melanoma (GEM) study, a large population-based study of primary cutaneous melanoma, we evaluated associations between number of nevi and patient features, including sun-sensitivity summarized in a phenotypic index, and tumor characteristics, and we assessed the association of nevus count with melanoma-specific survival. Higher nevus counts were independently and positively associated with male gender and younger age at diagnosis and inversely associated with lentigo maligna histology. We observed a borderline significant trend of poorer melanoma-specific survival with increasing quartile of nevus count, but little or no association between number of nevi and pigmentary phenotypic characteristics or prognostic tumor features.

Melanomas arising from mucosa are rare and associated with a poor prognosis. This study aims to provide an analysis of metastatic pathways, time intervals, factors influencing metastatic spread and organs for distant metastases. A total of 116 patients with mucosal melanomas of different sites were included. The mean follow-up interval was 47 ± 52 months. Patients were assigned to two different metastatic pathways, either presenting loco-regional lymph node metastases as first spread or direct distant metastases. The distribution of distant metastases was assessed. Twenty-six patients presented with a pre-existing metastatic spread and were not assigned to pathways. Of the included patients, 44 developed metastases after treatment of the primary tumour; 25 patients directly developed distant metastases; 16 patients developed regional lymph node metastases prior to distant metastases. Location of the primary tumour in the upper airway or GI tract and advanced T stage were significant risk factors of direct distant metastases. Distant metastases are mainly located in the lung, the liver and non-regional lymph nodes. Mucosal melanomas show a high rate of direct distant metastases rather than regional lymph node metastases. Thus the follow-up should always include a whole-body cross-sectional imaging in high-risk tumours. • Mucosal melanomas show a high rate of direct distant metastases. • T stage and primary location are predictors for direct distant metastases. • Distant metastases were mainly found in lung, liver and lymph nodes. • Follow-up of a high-risk mucosal melanoma should include whole-body imaging.

Patients with melanoma brain metastases (MBM) have been excluded from trials evaluating immunotherapy in melanoma. As such, immunotherapy's role in MBM is poorly understood, particularly in combination with radiotherapy. The National Cancer Database was queried for patients with MBM receiving brain radiotherapy. They were classified according to immunotherapy receipt. Multivariate Cox regression was performed to identify factors associated with survival. Among 1287 patients, 185 received immunotherapy. Factors associated with improved survival included younger age, academic facility, lower extracranial disease burden, stereotactic radiotherapy, chemotherapy, and immunotherapy. Adding immunotherapy to radiotherapy for MBM is associated with improved survival. Copyright © 2017 Elsevier B.V. All rights reserved.

Despite several therapeutic advances, malignant melanoma still remains a fatal disease for which novel and long-term curative treatments are needed. The successful development of innovative therapies strongly depends on the availability of appropriate pre-clinical models. For this purpose, several mouse models holding the promise to provide insight into molecular biology and clinical behavior of melanoma have been generated. The most relevant ones and their contribution for the advancement of therapeutic approaches for the treatment of human melanoma patients will be here summarized. However, as models, mice do not recapitulate all the features of human melanoma, thus their strengths and weaknesses need to be carefully identified and considered for the translation of the results into the human clinics. In this panorama, the concept of comparative oncology acquires a priceless value. The revolutionary importance of spontaneous canine melanoma as a translational model for the pre-clinical investigation of melanoma progression and treatment will be here discussed, with a special consideration to the development of innovative immunotherapeutic approaches.

Primary mucosal melanoma of the head and neck (MMHN) comprises approximately 1% of all malignant melanomas. It presents more commonly in an elderly population and has no significant gender predominance. Given its rarity, most evidence of the causes, behavior, and treatment approaches for MMHN originates from isolated case reports and retrospective series. Between 1945 and 2011, at least 1951 cases of MMHN have been reported in the literature. Despite numerous technological developments in surgery and radiation therapy, as well as advances in systemic modalities, MMHN is an aggressive malignancy with a very poor prognosis. Complete surgical excision with clear margins remains the primary treatment modality. Adjuvant postoperative radiation therapy may improve locoregional control but does not appear to affect survival. Definitive particle radiation therapy promises to provide high rates of local control for nonoperable patients. Recent molecular evidence suggests that proto-oncogene KIT aberrations in a subset of mucosal melanomas may represent a potential diagnostic value and serve as a therapeutic target for tyrosine kinase inhibitors in an adjuvant setting for patients with advanced MMHN.

The objectives of this analysis were to compare various measures associated with lymph node (LN) dissection and to identify threshold values associated with disease-specific survival (DSS) outcomes in patients with melanoma. Patients with lymph node-positive melanoma who underwent therapeutic LN dissection of the neck, axilla, and inguinal region were identified from the SEER database (1988-2005). We performed Cox multivariate analyses to determine the impact of the total number of LNs removed, number of negative LNs removed, and LN ratio on DSS. Multivariate cut-point analyses were conducted for each anatomic region to identify the threshold values associated with the largest improvement in DSS. The LN ratio was significantly associated with DSS for all LN regions. The LN ratio thresholds resulting in the greatest difference in 5-year DSS were .07, .13, and .18 for neck, axillary, and inguinal regions, respectively, corresponding to 15, 8, and 6 LNs removed per positive lymph node. After adjustment for other clinicopathologic factors, the hazard ratios (HRs) were .53 (95% confidence interval [CI], .40 to .71) in the neck, .52 (95% CI, .42 to .65) in the axillary, and .47 (95% CI, .36 to .61) in the inguinal regions for patients who met the LN ratio threshold. Among the prognostic factors examined, LN ratio was the best indicator of the extent of LN dissection, regardless of anatomic nodal region. These data provide evidence-based guidelines for defining adequate LN dissections in melanoma patients. (c) 2009 American Cancer Society.

Combined BRAF-MEK inhibitor therapy is the standard of care for BRAF V600 -mutant advanced melanoma. We investigated encorafenib, a BRAF inhibitor with unique target-binding properties, alone or in combination with the MEK inhibitor binimetinib, versus vemurafenib in patients with advanced BRAF V600 -mutant melanoma. COLUMBUS was conducted as a two-part, randomised, open-label phase 3 study at 162 hospitals in 28 countries. Eligible patients were aged 18 years or older and had histologically confirmed locally advanced (American Joint Committee on Cancer [AJCC] stage IIIB, IIIC, or IV), unresectable or metastatic cutaneous melanoma, or unknown primary melanoma; a BRAF V600E or BRAF V600K mutation; an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; and were treatment naive or had progressed on or after previous first-line immunotherapy. In part 1 of the study, patients were randomly assigned (1:1:1) via interactive response technology to receive either oral encorafenib 450 mg once daily plus oral binimetinib 45 mg twice daily (encorafenib plus binimetinib group), oral encorafenib 300 mg once daily (encorafenib group), or oral vemurafenib 960 mg twice daily (vemurafenib group). The primary endpoint was progression-free survival by blinded independent central review for encorafenib plus binimetinib versus vemurafenib. Efficacy analyses were by intention-to-treat. Safety was analysed in patients who received at least one dose of study drug and one postbaseline safety assessment. The results of part 2 will be published separately. This study is registered with ClinicalTrials.gov, number NCT01909453, and EudraCT, number 2013-001176-38. Between Dec 30, 2013, and April 10, 2015, 577 of 1345 screened patients were randomly assigned to either the encorafenib plus binimetinib group (n=192), the encorafenib group (n=194), or the vemurafenib group (n=191). With a median follow-up of 16·6 months (95% CI 14·8-16·9), median progression-free survival was

Purpose Sorafenib is an inhibitor of VEGFR, PDGFR, and RAF kinases, amongst others. We assessed the association of somatic mutations with clinicopathologic features and clinical outcomes in patients with metastatic melanoma treated on E2603, comparing treatment with carboplatin, paclitaxel +/− sorafenib (CP vs. CPS). Experimental Design Pre-treatment tumor samples from 179 unique individuals enrolled on E2603 were analyzed. Genotyping was performed using a custom iPlex panel interrogating 74 mutations in 13 genes. Statistical analysis was performed using Fisher’s exact test, logistic regression, and Cox’s proportional-hazards models. Progression free survival and overall survival were estimated using Kaplan-Meier methods. Results BRAF and NRAS mutations were found at frequencies consistent with other metastatic melanoma cohorts. BRAF-mutant melanoma was associated with worse performance status, increased number of disease sites, and younger age at diagnosis; NRAS-mutant melanoma was associated with better performance status, fewer sites of disease, and female gender. BRAF and NRAS mutations were not significantly predictive of response or survival when treated with CPS vs. CP. However, patients with NRAS-mutant melanoma trended towards a worse response and PFS on CP than those with BRAF-mutant or WT/WT melanoma, an association that was reversed for this group on the CPS arm. Conclusions This study of somatic mutations in melanoma is the last prospectively collected phase III clinical trial population prior to the era of BRAF targeted therapy. A trend towards improved clinical response in patients with NRAS-mutant melanoma treated with CPS was observed, possibly due to sorafenib’s effect on CRAF. PMID:24714776

Low phenylalanine (phe) and tyrosine (tyr) diets limit tumour growth in animal models and may offer a novel cancer therapy. We studied the efficacy and acceptability of a low phe and tyr diet in patients with advanced cancer. Patients with advanced metastatic melanoma (n=22) and metastatic breast cancer (n=15) were invited to follow a low phe and tyr diet (10 mg kg-1 phe and tyr per day) for 1 month. In those individuals who followed the diet for 1 month, we attempted to establish the effects on nutritional status (body weight, fat free mass, percentage body fat, serum albumin), immune cell function (white cell count, lymphocytes and neutrophils), plasma levels of phe-tyr and tryptophan and quality of life (Hospital Anxiety and Depression score). Only three of the 22 patients with metastatic melanoma and three of the 15 patients with metastatic breast cancer agreed to start the diet. All patients experienced problems and side-effects and increases in anxiety and depression. There were declines in weight, with loss of fat and fat free mass but slight increases in white cell counts and neutrophils. Low phe and tyr diets do not appear to be a viable treatment option for patients with advanced cancer.

GENETIC COUNSELLING IN MELANOMA

Summary Genetic counselling may be offered to families with melanoma and to individuals with multiple melanomas to better understand the genetic susceptibility of the disease, the influence of environmental factors, the inheritance of the risk and behaviour that decreases the risk of dying from melanoma including specific dermatological follow-up such as total body photography and digital dermoscopy. Genetic testing may be offered to those individuals with more than a 10% chance of being a carrier of a mutation. This risk varies according to the incidence of melanoma in the country and sun behaviour. In countries with a low-medium incidence of melanoma, genetic testing should be offered to families with two cases of melanoma or an individual with two primary melanomas. In countries with a high incidence, families with three cases of melanoma, with two melanomas and one pancreatic adenocarcinoma, or patients with three primary melanomas may benefit from genetic testing.

Multiple lymphatic basin drainage (MLBD) is frequently observed in patients with trunk melanoma undergoing sentinel lymph node (SLN) biopsy. Conflicting data regarding the prognostic association of MLBD in SLN-negative patients have been reported. This study aimed to investigate the prognostic role of MLBD in patients with negative SLN biopsy. Retrospective data from 656 melanoma patients who underwent a SLN biopsy (1991-2012) at six Italian centers were gathered in a multicenter database. MLBD was defined as lymphoscintigraphic and intraoperative identification of an SLN in more than one nodal basin. Clinical and pathologic variables were recorded and analyzed for their impact on survival. SLN-negative patients with MLBD were at lower risk of melanoma recurrence [hazard ratio (HR) 0.73, P = 0.05) and melanoma-related death (HR 0.68, P = 0.001) independent of common staging features. Multivariable Cox analyses of disease-free interval (DFI) and disease-specific survival (DSS) showed that MLBD maintained a favorable role and ulceration an unfavorable role. Histologic regression was independently associated only with DFI. When survival was stratified according to presence of MLBD, histologic regression and Breslow thickness <2 mm were associated with improved DFI (5-year DFI: 96.9 vs. 66,1 %, respectively; HR 0.48, P < 0.001) and DSS (5-year DSS: 96.7 vs. 71.8 %, respectively; HR 0.52, P = 0.005) compared to patients without these three favorable parameters. Patients with negative SLN biopsy results have better prognosis when two or more lymphatic basins are identified and analyzed. Further research is required to investigate the mechanisms behind this evidence.

Class III β-tubulin (TUBB3) has been recognized as being associated with resistance to taxane-based regimens in several cancers. However, little is known about the clinicopathological significance of TUBB3 expression in patients with cutaneous malignant melanoma. The aim of this study was to examine the prognostic significance of TUBB3 expression in cutaneous malignant melanoma. A total of 106 patients with surgically resected cutaneous malignant melanoma were assessed. Tumour sections were immunohistochemically stained for TUBB3, Ki-67 and microvessel density with CD34. TUBB3 was highly expressed in 80% (85/106) of patients. No statistically significant relationship was observed between the high expression of TUBB3 and any variables. On univariate analysis, ulceration, disease stage, TUBB3 and CD34 revealed a significant relationship with overall survival and progression-free survival. Multivariate analysis confirmed that a low TUBB3 expression was an independent prognostic factor for poor prognosis of cutaneous malignant melanoma. The decreased expression of TUBB3 could be a significant marker for predicting unfavourable prognosis in patients with cutaneous malignant melanoma.

Mucosal melanoma: an update.

Mucosal melanoma is a rare melanoma subtype that differs from the cutaneous form of the tumor in its biology, clinical manifestations, and management. Diagnosis is usually late due to a lack of early or specific signs and the location of lesions in areas that are difficult to access on physical examination. Surgical excision is the treatment of choice for localized disease. The value of sentinel lymph node biopsy and lymphadenectomy is still unclear. Radiotherapy can be used as adjuvant therapy for the control of local disease. c-KIT mutations are more common than in other types of melanoma and this has led to significant advances in the use of imatinib for the treatment of metastatic mucosal melanoma.

Background Our previous experience monitoring nevi in high risk patients by serial digital epiluminescence microscopy (DELM) photography achieved low biopsy rates, but was limited by melanomas presenting as new lesions or arising from nevi that had not been photographed. Objective To determine whether biopsy rates, efficiency of melanoma detection, and melanoma origin (de novo vs. nevus-derived) differed in a similar patient population monitored by total body (TB) photography. Methods 1076 patients (including 187 from prior cohort) underwent TB photography and were monitored using photographs obtained at the initial visit. Risk factors and median monitoring periods for these patients were comparable to patients previously monitored by DELM photography. Results 275 biopsies were performed in 467 patients on follow-up visits. Of 12 melanomas detected on follow-up, five were invasive; five presented as changing lesions and two as new lesions; nine arose de novo and the remainder was nevus-derived. Conclusions In our experience with both approaches, monitoring patients at risk for melanoma by TB (compared to DELM) photography was associated with lower biopsy rates and lower nevus to melanoma ratios, and facilitated detection of both new and changing lesions. In both cohorts, the majority of melanomas detected on follow-up arose de novo. PMID:20653722

The biological behavior of melanoma is unfavorable in the elderly when compared to young subjects. We hypothesized that differences in T-cell responses might underlie the distinct behavior of melanoma in young and old melanoma patients. Therefore, we investigated the circulating T-cell compartment of 34 patients with metastatic melanoma and 42 controls, which were classified as either young or old. Absolute numbers of CD4+ T cells were decreased in young and old melanoma patients when compared to the age-matched control groups. Percentages of naive and memory CD4+ T cells were not different when comparing old melanoma patients to age-matched controls. Percentages of memory CD4+ T cells tended to be increased in young melanoma patients compared to young controls. Proportions of naive CD4+ T cells were lower in young patients than in age-matched controls, and actually comparable to those in old patients and controls. This was accompanied with increased percentages of memory CD4+ T cells expressing HLA-DR, Ki-67, and PD-1 in young melanoma patients in comparison to the age-matched controls, but not in old patients. Proportions of CD45RA-FOXP3 high memory regulatory T cells were increased in young and old melanoma patients when compared to their age-matched controls, whereas those of CD45RA+FOXP3 low naive regulatory T cells were similar. We observed no clear modulation of the circulating CD8+ T-cell repertoire in melanoma patients. In conclusion, we show that CD4+ T cells of young melanoma patients show signs of activation, whereas these signs are less clear in CD4+ T cells of old patients.

Diagnosis and treatment of tumors of the eye is extremely difficul; surgical treatment in advanced stages, when the tumor grows in the orbit, leads to extensive radical surgery of the face. The extent and nature of surgical procedures depends on the nature of the tumor process, in advanced stages is indicated mutilating surgery--exenteration of the orbit. Exenteration of the orbit due to the extrascleral extension of malignant melanoma of the uvea is very rare, unfortunately, even today in certain cases it is necessary to make such a mutilating surgery. Case report--65 year old female patient, sent to our Departement in 2008 with the finding of the pigment deposits on the posterior pole of the left eye. Ultrasound study found elevations of up to 3 mm, she was asked to come for further control in three months interval. She did not coma, furthermore she sporadically attended another eye clinic. In 2011 she was treated for secondary glaucoma--cyclocryopexia. Due to pain another surgery--tarzoraphia was indicated. In 2012 she underwent surgery at St. Elisabeth Cancer Institute in Bratislava--Nefrectomia transperitoneally l. dx., excision hepatis. Histological examination in addition to the primary papillary renal carcinoma--mucinous tubular T1 Nx Mx type, found the metastasis of malignant melanoma to the liver and right kidney. She underwent the diagnostic procedure to find the origo of the melanoma. The patient was subsequently admitted to our clinic with blind painfull eye for enucleation. During the surgery the was found retrobulbar tumor ingrowth. Histopatholigical findings confirmed malignant melanoma. Indicated was exenteration of the orbit due to malignant melanoma T4 N0 M2 stage in June 2012. After healing of the cavity she was recommended to design an individual prosthesis. After completing several courses of palliative chemotherapy during a recent review in January 2015 the patient is without recurrence of the melanoma in the orbit Histological examination

Despite an increasing number of promising treatment options, only a limited number of studies concerning melanoma patients' psycho-oncological distress have been carried out. However, multiple screening tools are in use to assess the need for psycho-oncological support. This study aimed first to identify parameters in melanoma patients that are associated with a higher risk for being psycho-oncologically distressed and second to compare patients' self-evaluation concerning the need for psycho-oncological support with the results of established screening tools.We performed a cross-sectional study including 254 melanoma patients from the Center for Dermatooncology at the University of Tuebingen. The study was performed between June 2010 and February 2013. Several screening instruments were included: the Distress Thermometer (DT), Hospital Anxiety and Depression Scale and the patients' subjective evaluation concerning psycho-oncological support. Binary logistic regression was performed to identify factors that indicate the need for psycho-oncological support.Patients' subjective evaluation concerning the need for psycho-oncological support, female gender, and psychotherapeutic or psychiatric treatment at present or in the past had the highest impact on values above threshold in the DT. The odds ratio of patients' self-evaluation (9.89) was even higher than somatic factors like female gender (1.85), duration of illness (0.99), or increasing age (0.97). Patients' self-evaluation concerning the need for psycho-oncological support indicated a moderate correlation with the results of the screening tools included.In addition to the results obtained by screening tools like the DT, we could demonstrate that patients' self-evaluation is an important instrument to identify patients who need psycho-oncological support.

To determine the frequency of naevus-associated melanoma among superficial spreading and nodular subtypes; and to investigate associations between naevus-associated melanoma and other clinico-pathological characteristics. Cross-sectional study of all patients with nodular and superficial spreading melanomas diagnosed between 1994 and 2015 at the Victorian Melanoma Service, Melbourne. Clinical and pathological characteristics of naevus-associated and de novo melanomas were assessed in univariable and multivariable logistic regression analyses. Of 3678 primary melanomas, 1360 (37.0%) were histologically associated with a naevus and 2318 (63.0%) were de novo melanomas; 71 of 621 nodular (11.4%) and 1289 of 3057 superficial spreading melanomas (42.2%) were histologically associated with a naevus. In multivariable analyses, the odds of being associated with a naevus were higher for melanomas located on the trunk (v head and neck: adjusted odds ratio [OR], 2.27; 95% CI, 1.73-2.96; P < 0.001), while the odds were lower for thicker tumours (adjusted OR, 0.75 per millimetre increase in Breslow thickness; 95% CI, 0.69-0.81; P < 0.001), amelanotic/hypomelanotic melanomas (adjusted OR, 0.68; 95% CI, 0.48-0.97; P = 0.035), and older age (patients 70 years or older v patients under 30 at diagnosis: adjusted OR, 0.28; 95% CI, 0.20-0.40; P < 0.001). After adjusting for confounders, the odds of an associated naevus was three times as high for superficial spreading melanomas as for nodular melanomas (adjusted OR, 3.05; 95% CI, 2.24-4.17; P < 0.001). Melanomas are most likely to arise in the absence of a pre-existing naevus, particularly nodular melanomas. Public health campaigns should therefore emphasise the detection of suspicious de novo lesions, as well as of changing lesions.

Factors known to affect melanoma survival include age at presentation, sex and tumor characteristics. Polymorphisms also appear to modulate survival following diagnosis. Result from other studies suggest that vitamin D receptor (VDR) polymorphisms (SNPs) impact survival in patients with glioma, renal cell carcinoma, lung, breast, prostate and other cancers; however, a comprehensive study of VDR polymorphisms and melanoma-specific survival is lacking. We aimed to investigate whether VDR genetic variation influences survival in patients with cutaneous melanoma. The analysis involved 3566 incident single and multiple primary melanoma cases enrolled in the international population-based Genes, Environment, and Melanoma Study. Melanoma-specific survival outcomes were calculated for each of 38 VDR SNPs using a competing risk analysis after adjustment for covariates. There were 254 (7.1%) deaths due to melanoma during the median 7.6 years follow-up period. VDR SNPs rs7299460, rs3782905, rs2239182, rs12370156, rs2238140, rs7305032, rs1544410 (BsmI) and rs731236 (TaqI) each had a statistically significant (trend P values < 0.05) association with melanoma-specific survival in multivariate analysis. One functional SNP (rs2239182) remained significant after adjustment for multiple testing using the Monte Carlo method. None of the SNPs associated with survival were significantly associated with Breslow thickness, ulceration or mitosis. These results suggest that the VDR gene may influence survival from melanoma, although the mechanism by which VDR exerts its effect does not seem driven by tumor aggressiveness. Further investigations are needed to confirm our results and to understand the relationship between VDR and survival in the combined context of tumor and host characteristics. PMID:26521212

Purpose Characterize tumor burden dynamics during PD-1 inhibitor therapy and investigate the association with overall survival (OS) in advanced melanoma. Experimental Design The study included 107 advanced melanoma patients treated with pembrolizumab. Tumor burden dynamics were assessed on serial CT scans using irRECIST and were studied for the association with OS. Results Among 107 patients, 96 patients had measurable tumor burden and 11 had non-target lesions alone at baseline. In the 96 patients, maximal tumor shrinkage ranged from -100% to 567% (median:-18.5%). Overall response rate was 44% (42/96; 5 irCR, 37 irPR). Tumor burden remained <20% increase from baseline throughout therapy in 57 patients (55%). Using a 3-month landmark analysis, patients with <20% tumor burden increase from baseline had longer OS than pts with ≥20% increase (12-month OS rate: 82 vs. 53%). In extended Cox models, patients with <20% tumor burden increase during therapy had significantly reduced hazards of death (HR=0.19, 95%CI:0.08–0.43, p<0.0001 univariate; HR=0.18, 95%CI:0.08-0.41, p<0.0001, multivariable). Four patients (4%) experienced pseudoprogression; 3 patients had target lesion increase with subsequent response, which was noted after confirmed irPD. One patient without measurable disease progressed with new lesion that subsequently regressed. Conclusions Tumor burden increase of <20% from the baseline during pembrolizumab therapy was associated with longer OS, proposing a practical marker for treatment decision guides that needs to be prospectively validated. Pseudoprogressors may experience response after confirmed irPD, indicating a limitation of the current strategy for immune-related response evaluations. Evaluations of patients without measurable disease may require further attention. PMID:28592629

Eighty-one cases of conjunctival melanoma treated between 1960 and 1988 were studied to determine factors that might affect outcome in patients with such lesions. The therapeutic procedures performed were local excision (16), local excision followed by brachytherapy with Sr-90/Y-90 (32), local excision followed by cryotherapy with liquid nitrogen (16), brachytherapy with Sr-90/Y-90 (12), local excision followed by external beam irradiation (3), and local excision followed by brachytherapy and cryotherapy (2). The median follow-up period was 5.5 years (longest 26, shortest 1 year). Sixty two patients (76.5%) showed a complete regression of the melanoma, 19 (23.5%) developed recurrences, and 15 (18.5%) died from metastases. The melanomas had developed with almost equal frequency from a pre-existing naevus (25.9%), from primary acquired melanosis (25.9%), and 'de novo' (30.9%). Small tumours had a higher chance of regressing (80.6%) than larger ones (68.6%). The cumulative survival rate was 76% after five years and 60% after 10 years from any causes of death and 87.6% after five years and 76.3% after 10 years from deaths caused by metastases. Most deaths from metastases occurred within 5 years. At 88.5%, the cumulative survival rate of patients with small tumours (less than one quadrant of the bulbar conjunctiva and less than 2 mm thickness) was significantly higher than that of patients with larger tumours (more than one quadrant of the bulbar conjunctiva and/or more than 2 mm thickness) with 65% after eight years. Local excision followed by beta ray irradiation (Sr-90/Y-90) or cryotherapy can be recommended as the treatment of choice. Nevertheless the behaviour of conjunctival melanomas remains unpredictable in individual cases. Images PMID:2285686

IMPORTANCE Previous studies have reported that histopathologically amelanotic melanoma is associated with poorer survival than pigmented melanoma; however, small numbers of amelanotic melanomas, selected populations, lack of centralized pathologic review, or no adjustment for stage limit the interpretation or generalization of results from prior studies.OBJECTIVE To compare melanoma-specific survival between patients with histopathologically amelanotic and those with pigmented melanoma in a large international population-based study.DESIGN, SETTING, AND PARTICIPANTS Survival analysis with a median follow-up of 7.6 years.The study population comprised 2995 patients with 3486 invasive primary melanomas centrally scored for histologic pigmentation from the Genes, Environment, and Melanoma(GEM) Study, which enrolled incident cases of melanoma diagnosed in 1998 through 2003 from international population-based cancer registries.MAIN OUTCOMES AND MEASURES Clinicopathologic predictors and melanoma-specific survival of histologically amelanotic and pigmented melanoma were compared using generalized estimating equations and Cox regression models, respectively.RESULTS Of 3467 melanomas, 275 (8%) were histopathologically amelanotic. Female sex,nodular and unclassified or other histologic subtypes, increased Breslow thickness, presence of mitoses, severe solar elastosis, and lack of a coexisting nevus were independently associated with amelanotic melanoma (each P < .05). Amelanotic melanoma was generally ofa higher American Joint Committee on Cancer (AJCC) tumor stage at diagnosis (odds ratios[ORs] [95%CIs] between 2.9 [1.8-4.6] and 11.1 [5.8-21.2] for tumor stages between T1b and T3b and ORs [95%CIs] of 24.6 [13.6-44.4] for T4a and 29.1 [15.5-54.9] for T4b relative to T1a;P value for trend, <.001) than pigmented melanoma. Hazard of death from melanoma was higher for amelanotic than for pigmented melanoma (hazard ratio [HR], 2.0; 95%CI, 1.4-3.0)(P < .001), adjusted for age, sex

There is a growing body of evidence highlighting the applications of computational modeling in the field of biomedicine. It has recently been applied to the in silico analysis of cancer dynamics. In the era of precision medicine, this analysis may allow the discovery of new molecular targets useful for the design of novel therapies and for overcoming resistance to anticancer drugs. According to its molecular behavior, melanoma represents an interesting tumor model in which computational modeling can be applied. Melanoma is an aggressive tumor of the skin with a poor prognosis for patients with advanced disease as it is resistant to current therapeutic approaches. This review discusses the basics of computational modeling in melanoma drug discovery and development. Discussion includes the in silico discovery of novel molecular drug targets, the optimization of immunotherapies and personalized medicine trials. Mathematical and computational models are gradually being used to help understand biomedical data produced by high-throughput analysis. The use of advanced computer models allowing the simulation of complex biological processes provides hypotheses and supports experimental design. The research in fighting aggressive cancers, such as melanoma, is making great strides. Computational models represent the key component to complement these efforts. Due to the combinatorial complexity of new drug discovery, a systematic approach based only on experimentation is not possible. Computational and mathematical models are necessary for bringing cancer drug discovery into the era of omics, big data and personalized medicine.

We evaluated the feasibility of using technology for melanoma patient education in a clinic setting. We assessed technology skill level and preferences for education. Data were collected using an adapted version of the Use of Technology Survey. Most participants owned a computer and DVD player and were skilled in the use of these devices, along with Internet and e-mail. Participants preferred the option of using in-clinic and at-home technology versus in-clinic only use. Computer and DVD applications were preferred because they were familiar and convenient. Using technology for patient education intervention is a viable option; however, patients' skill level and preferences for technology should be considered.

Careful monitoring of regional lymph nodes and early detection of metastases in malignant melanoma patients has an impact on their survival, since it may permit beneficial surgical therapy. Palpation is routinely used in clinical practice. The value of ultrasonography for routine follow-up of melanoma patients, still, is not generally accepted. The aim of our study was to assess the sensitivity and specificity of ultrasound and clinical examination respectively, in the detection of melanoma regional node metastases. Additionally, we evaluated whether early detection of metastases improved overall survival. One hundred and forty-eight melanoma patients with an intermediate or thick primary lesion were followed between January 1997 and May 2001. Clinical examination and concomitant regional lymph node ultrasonography were performed, every 3-4 months. If suspicious findings were identified, regional lymph node dissection was undertaken. Forty-four from the initial 148 patients relapsed with regional lymph nodal metastases. In 11 patients (25%) palpation failed to reveal the disease and metastases were depicted only by ultrasonography. In only 1 patient ultrasonography was false-negative. The sensitivity and specificity of palpation were 72.7 and 97% respectively, while those of ultrasonography were 97.7 (p<0.001) and 98% respectively. Ultrasonography was more sensitive in detecting lymph node metastases in the axilla (100%) and the groin (93.3%). When overall survival of patients presenting with local-regional recurrence was calculated--depending on the number of involved lymph nodes--a survival benefit (p<0.05) was found for patients with only one lymph node metastasis. In conclusion, ultrasonography is superior to clinical examination in the early detection of regional lymph node metastases from an intermediate or thick malignant melanoma and should be a part of those patients' surveillance.

Patients with mucosal and acral melanomas have limited treatment options and a poor prognosis. Mutations of the KIT oncogene in these melanoma subtypes provide a potential therapeutic target. A multicenter phase 2 trial of sunitinib was conducted in patients with unresectable stage III or IV melanoma of a mucosal or acral primary origin. Patients were treated in 2 cohorts: cohort A received sunitinib at a dose of 50 mg daily for 4 weeks of a 6-week cycle, and cohort B received sunitinib at a dose of 37.5 mg daily on a continuous basis. Dose reductions were permitted for treatment-related toxicities, and tumor assessments were performed every 2 months. Fifty-two patients were enrolled: 21 in cohort A and 31 in cohort B. Four patients had confirmed partial responses, which lasted 5 to 10 months (1 with a KIT mutation). In both cohorts, the proportion of patients alive and progression-free at 2 months was 52% (95% confidence interval, 38%-66%); this was significantly larger than the hypothesized null of 5%. There was no significant difference in response or overall survival between the 25% of patients with a KIT mutation and those without one (response rate, 7.7% vs 9.7%; overall survival, 6.4 vs 8.6 months). The overall disease control rate was 44%, and a high rate of toxicity was associated with the treatment. Sunitinib showed activity in the treatment of mucosal and acral melanoma that was not dependent on the presence of a KIT mutation. However, the medication was poorly tolerated, and there were no prolonged responses. Cancer 2015;121:4007-4015. © 2015 American Cancer Society. © 2015 American Cancer Society.

Treatment options for metastatic melanoma in Serbia are limited due to the lack of newly approved biologic agents and the lack of clinical studies. Also, there is a paucity of data regarding the treatment approaches in different tertiary centers and efficacy of available chemotherapy protocols. The aim of this study was to obtain more detailed data about treatment protocols in Serbia based on structured survey in tertiary oncology centers. Data about the melanoma patients treated in 2011 were analyzed from hospital databases in 6 referent oncology centers in Serbia, based on the structured survey, with the focus on metastatic melanoma patients (unresectable stage IIIC and IV). A total of 986 (79-315 in different centers) patients were treated, with 320 (32.45%) newly diagnosed patients. There were 317 patients in stage IIIC/IV, 77/317 aged < 50 years. At the time of diagnosis 47.3% of patients were < 60 years of age (24.2% < 40 years, 23% 50-59 years, 52.6% > 60 years). At initial diagnosis 12.5% of patients were in stage III and 4.5% in stage IV. The most common type was superficial spreading melanoma (50-660), followed by nodular melanoma (23.5-50%). Apart from the regional and distant lymph node metastases, the most frequent organs involved in stage IV disease were distant skin and soft tissues (12-55%), lungs (19-55.5%), liver (10-60%), and bones (3-10%). The first line therapy in stage IV metastatic melanoma was dacarbazine (DTIC) dimethyl-triazenoimidozole-carboxamide in 61-93% of the patients, while the second line varied between the centers. Disease control (complete response + partial response + stable disease) was achieved in 25.7% of the patients treated with the first line chemotherapy and 23.1% of the patients treated with the second line therapy, but the duration of response was short, in first-line therapy 6.66 +/- 3.36 months (median 6.75 months). More than 90% of patients were treated outside the clinical trials. Based on this survey, there is a

Recently, the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) has been widely evaluated in many cancers. Here we assessed the prognostic value of pretreatment NLR in melanoma. A range of online databases was systematically searched up to March,2018 for identify available studies which assessed the prognostic significance of NLR. Data from studies reporting a hazard ratio (HR) and 95% confidence interval (CI) were weighted by generic inverse-variance and pooled in random effects meta-analysis. Twelve studies with 4593 individuals were included. Patients with elevated NLR had a significantly shorter overall survival (OS) (HR: 1.56, 95% CI: 1.28-1.90, p < .001) and disease-free survival (DFS)/progression-free survival (PFS) (HR = 1.86; 95% CI = 1.24-2.80; P = .003). Subgroup analyses showed that the negative prognostic effect of elevated NLR on OS remained substantial in North American and Europen populations and patients with non-metastatic and metastatic stage. Additionally, elevated NLR was related to worse OS in patients with melanoma, regardless of the sample size and the cut-off value. Our findings suggest that elevated pretreatment NLR was associated with poor prognosis in melanoma patients, suggesting NLR might be a prognostic factor in patients with melanoma.

Melanoma survivors are at an increased risk of developing other malignancies, including keratinocyte skin cancer (KSC). While it is known that many risk factors for melanoma also impact risk of KSC in the general population, no previous study has investigated risk factors for KSC development in melanoma patients. We assessed associations of personal and clinical characteristics, including skin phenotype and variations in the melanocortin 1 receptor (MC1R) gene, with KSC risk in melanoma patients. We used prospective follow-up information on 1200 patients treated for melanoma at the Instituto Valenciano de Oncología, Spain, between 2000 and 2011. We computed hazard ratios and 95% confidence intervals (CIs) for the association of clinical, personal and genetic characteristics with risk of KSC, squamous cell carcinoma (SCC), or basal cell carcinoma (BCC) from Cox proportional hazard models. Five-year cumulative incidence based on competing risk models of SCC, BCC or KSC overall was computed using multivariate subdistribution hazard models. To assess predictive performance of the models, we computed areas under the receiver-operating characteristic curves (AUCs, discriminatory power) using cross-validation. Median follow-up was 57.2 months; a KSC was detected in 163 patients (13.6%). In multivariable Cox models, age, sex, sunburns, chronic sun exposure, past personal history of non-melanoma skin cancer or other non-cutaneous neoplasia, and the MC1R variants p.D294H and p.R163Q were significantly associated with KSC risk. A cumulative incidence model including age, sex, personal history of KSC, and of other non-cutaneous neoplasia had an AUC of 0.76 (95% CI: 0.71-0.80). When p.D294H and p.R163Q variants were added to the model, the AUC increased to 0.81 (95% CI: 0.77-0.84) (p-value for difference <0.0001). In addition to age, sex, skin characteristics, and sun exposure, p.R163Q and p.D294H MC1R variants significantly increased KSC risk among melanoma patients. Our

Isolated limb infusion (ILI) is a simple yet effective alternative to conventional isolated limb perfusion for the treatment of advanced melanoma of the extremities. The study group comprised 13 patients with very advanced limb disease who had failed to achieve a satisfactory response to one or more ILIs with melphalan, and in whom amputation was the only other realistic treatment option. The aim of this study was to evaluate the efficacy and toxicity of ILI with fotemustine after systemic chemosensitisation with dacarbazine (DTIC). Complete remission was achieved in four patients and partial remission in eight patients, with a median response duration of 3 months. Limb salvage was achieved in five of 12 assessable patients (42%). Limb toxicity peaked 9 days after ILI; two patients experienced Wieberdink grade IV (severe) toxicity and four patients had grade V toxicity (requiring early amputation). ILI with fotemustine after DTIC chemosensitisation can be successful when gross limb disease has not been controlled by one or more ILIs with melphalan. However, it cannot be recommended as a routine method of treatment for advanced melanoma of the extremities because of the high incidence of severe limb toxicity.

Melanoma rarely invades the cerebellopontine angle (CPA) and can evade accurate diagnosis, which may alter management decisions. Diagnosis may be facilitated via careful history, magnetic resonance imaging (MRI) findings, and cerebrospinal fluid (CSF) analysis. Retrospective case review. Tertiary referral center. Thirteen internal auditory canal/CPA lesions in eight patients who presented with CPA syndrome and who had a pathological diagnosis consistent with malignant melanoma. There were four bilateral and four unilateral lesions. Six of eight patients had a history of melanoma. One was apparently primary CPA lesion, whereas all others were metastatic. T1- and T2-weighted precontrast and postcontrast gadolinium-enhanced MRI were obtained, including fat suppression and fluid-attenuated inversion recovery sequence images in two patients; lumbar puncture with CSF centrifugation and cytological analysis confirmed the diagnosis in two patients. Translabyrinthine craniotomy was performed for tumor extirpation in five patients. Symptoms at presentation, MRI findings, presence of malignant cells in CSF, tumor progression, intraoperative findings, response to treatment, time interval from initial diagnosis of melanoma elsewhere, and survival. Seven of eight patients had history and/or MRI findings suggestive of malignancy in the internal auditory canal and/or CPA, and diagnosis was confirmed via CSF analysis in two patients. In one patient, diagnosis was made at surgery. Internal auditory canal melanoma portends a grim prognosis, can occur up to 17 years after initial melanoma diagnosis/treatment, and can be detected with appropriate MRI sequences, especially enhanced fluid-attenuated inversion recovery images. In disseminated cases, diagnosis can be confirmed with lumbar puncture demonstrating malignant cells. Management includes tumor resection when melanoma seems to be solitary and malignant cells are not present in CSF. Intrathecal chemotherapy and radiation are

We vaccinated metastatic melanoma patients with irradiated, autologous melanoma cells genetically engineered to secrete interleukin 2 (IL-2) to investigate whether an anti-tumor immune response would be induced. Melanoma cell cultures were established from surgical specimens and were engineered to secrete IL-2 by infection with recombinant retrovirus. Twelve patients were vaccinated subcutaneously one, two, or three times with approximately 10(7) irradiated, autologous, IL-2-secreting tumor cells. Treatment was well tolerated, with local reactions at 11 of 24 injection sites and minor systemic symptoms of fever and headache after 6 injections. One patient developed anti-tumor DTH after the first vaccination and showed an increased response after the second vaccination. Anti-autologous tumor CTLs could be detected prevaccination in the peripheral blood of seven patients and their activity increased after vaccination in four patients. No UICC-defined clinical responses were seen, but three patients had stable disease for 7-15 months, one of whom has not yet progressed (15+ months). Thus, patient vaccination with autologous, genetically engineered tumor cells is feasible and safe. Anti-tumor DTH and CTLs can be induced in some patients with such a vaccine.

Purpose Mucosal melanoma is an aggressive malignancy with a poor response to conventional therapies. The efficacy and safety of nivolumab (a programmed death-1 checkpoint inhibitor), alone or combined with ipilimumab (a cytotoxic T-lymphocyte antigen-4 checkpoint inhibitor), have not been reported in this rare melanoma subtype. Patients and Methods Data were pooled from 889 patients who received nivolumab monotherapy in clinical studies, including phase III trials; 86 (10%) had mucosal melanoma and 665 (75%) had cutaneous melanoma. Data were also pooled for patients who received nivolumab combined with ipilimumab (n = 35, mucosal melanoma; n = 326, cutaneous melanoma). Results Among patients who received nivolumab monotherapy, median progression-free survival was 3.0 months (95% CI, 2.2 to 5.4 months) and 6.2 months (95% CI, 5.1 to 7.5 months) for mucosal and cutaneous melanoma, with objective response rates of 23.3% (95% CI, 14.8% to 33.6%) and 40.9% (95% CI, 37.1% to 44.7%), respectively. Median progression-free survival in patients treated with nivolumab combined with ipilimumab was 5.9 months (95% CI, 2.8 months to not reached) and 11.7 months (95% CI, 8.9 to 16.7 months) for mucosal and cutaneous melanoma, with objective response rates of 37.1% (95% CI, 21.5% to 55.1%) and 60.4% (95% CI, 54.9% to 65.8%), respectively. For mucosal and cutaneous melanoma, respectively, the incidence of grade 3 or 4 treatment-related adverse events was 8.1% and 12.5% for nivolumab monotherapy and 40.0% and 54.9% for combination therapy. Conclusion To our knowledge, this is the largest analysis of data for anti-programmed death-1 therapy in mucosal melanoma to date. Nivolumab combined with ipilimumab seemed to have greater efficacy than either agent alone, and although the activity was lower in mucosal melanoma, the safety profile was similar between subtypes.

Topical application of a potent immunological modulator, imiquimod, followed by laser irradiation has been used for the treatment of late-stage melanoma patients. This novel approach, laser-assisted laser immunotherapy (LIT), targets the root course of melanoma, a highly metastatic cancer. We started a phase I clinical trial in 2006 with promising initial outcomes. The laser-imiquimod combination showed significant palliative effects for these patients with multiple treatment cycles. For the returning patients, we found that the recurrent tumors were less aggressive than usually seen in untreated patients. The current protocol uses a light-absorbing dye for selective laser photothermal interaction with a non-invasive treatment mode. It has limitations for patient treatment, particularly for large, deeper tumors, and for patients with dark pigmented skins. This study provides some information on the treated patients (both stage IV and stage IV) during the past several years. We also discuss the future directions of LIT, particularly in the area of photothermal treatment mode with a new approach of interstitial irradiation. The current results in melanoma treatment using LIT indicate that the combination of photothermal therapy and immunological stimulation may hold the key for the treatment of late-stage, metastatic cancers, not only for cutaneous cancers such as melanoma and breast cancer, but also for deep and internal tumors using different operations modes such as interstitial laser irradiation.
