    Purpose: Stereotactic radiosurgery is an alternative option to neurosurgical excision in the management of patients with brain metastases. We retrospectively analyzed patients with brain metastases of malignant melanoma who were treated at our institution for outcome and prognostic factors. Patients and Methods: 64 patients with 122 cerebral metastases were treated with stereotactic radiosurgery between 1986 and 2000. Twelve patients (19%) showed neurologic symptoms at the time of treatment, and 46 patients (72%) had extracerebral tumor manifestation at that time. The median dose to the 80% isodose line, prescribed to encompass the tumor margin, was 20 Gy (range, 15-22 Gy). Results: Neurologic symptoms improved in five of twelve symptomatic patients. 41 patients remained asymptomatic or unchanged in their neurologic symptoms. Only five patients (8%) temporarily worsened neurologically after therapy despite no signs of tumor progression. With a mean follow-up time of 9.4 months, actuarial local control was 81% after 1 year. There was a statistically significant dose and size dependency of local tumor control. Median actuarial survival after treatment was 10.6 months. Patients without extracerebral tumor manifestation showed a superior survival (p = 0.04). Conclusions: Despite high local tumor control rates, the prognosis of patients with cerebral metastases of malignant melanoma remains poor. Stereotactic radiosurgery has the potential of stabilizing or improving neurologic symptoms in these patients in a palliative setting. (orig.)

    Purpose: Ipilimumab and radiation therapy (RT) are standard treatments for advanced melanoma; preclinical models suggest the potential for synergy. However, limited clinical information exists regarding safety and optimal timing of the combination. Methods and Materials: We reviewed the records of consecutive patients with unresectable stage 3 or 4 melanoma treated with ipilimumab. Patients were categorized as having received RT or not. Differences were estimated between these 2 cohorts. Results: We identified 88 patients treated with ipilimumab. At baseline, the ipilimumab-plus-RT group (n=44) had more unfavorable characteristics. Despite this, overall survival, progression-free survival, and both immune-related and non–immune-related toxicity were not statistically different (P=.67). Patients who received ipilimumab before RT had an increased duration of irradiated tumor response compared with patients receiving ipilimumab after RT (74.7% vs 44.8% at 12 months; P=.01, log-rank test). In addition, patients receiving ablative RT had non–statistically significantly improved median overall survival (19.6 vs 10.2 months), as well as 6-month (95.1% vs 72.7%) and 12-month (79.7% vs 48.5%) survival rates, compared with those treated with conventionally fractionated RT. Conclusions: We found that both ablative and conventionally fractionated RT can be safely administered with ipilimumab without a clinically apparent increase in toxicity. Patients who received ipilimumab before RT had an increased duration of irradiated tumor response.

    Dendritic cells (DC) are the most potent antigen presenting cells and have proven effective in stimulation of specific immune responses in vivo. Competing immune inhibition could limit the clinical efficacy of DC vaccination. In this phase II trial, metronomic Cyclophosphamide and a Cox-2 inhibitor...... have been added to a DC vaccine with the intend to dampen immunosuppressive mechanisms. Twenty-eight patients with progressive metastatic melanoma were treated with autologous DCs pulsed with survivin, hTERT, and p53-derived peptides (HLA-A2(+)) or tumor lysate (HLA-A2(-)). Concomitantly the patients...... were treated with IL-2, Cyclophosphamide, and Celecoxib. The treatment was safe and tolerable. Sixteen patients (57 %) achieved stable disease (SD) at 1st evaluation and 8 patients had prolonged SD (7-13.7 months). The median OS was 9.4 months. Patients with SD had an OS of 10.5 months while patients...

    Full Text Available Since the efficacy of ipilimumab on nivolumab-resistant advanced melanoma is extremely low, additional supportive therapy for anti-PD-1 antibody therapy-resistant advanced melanoma is needed. Although several supportive therapies that enhance the antitumor immune response of anti-PD-1 antibodies have already been reported, unexpected immune-related adverse events were detected at the same time. In this report, we describe a patient with advanced melanoma treated with nivolumab followed by intensity-modulated radiotherapy, which might have triggered bullous pemphigoid (BP. Although several cases of BP developing in anti-PD-1 antibody-treated patients have already been reported, in this report, we shed light on the possible pathogenesis of BP developing in a patient treated with nivolumab through M2 macrophages.

    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.

    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.

    Purpose: To determine the relationship between the long-term visual function and the dose and dose rates delivered to critical ocular structures in patients with choroidal melanoma treated with 125 I episcleral plaque radiotherapy. Methods and Materials: From 1987 to 1994, 63 patients underwent 125 I episcleral plaque (Collaborative Ocular Melanoma Study [COMS] design) application for the treatment of choroidal melanoma. The mean tumor height was 4.5 mm (range 1.7-8.3). Doses and dose rates at the tumor apex, macula, and optic disc were calculated. Forty-three records were scored to assess whether a decrease in visual acuity of >2 lines on a standard Snellen eye chart had occurred. Patient age and the presence of hypertension or diabetes were noted. Statistical analysis was performed to assess both the rate at which visual decline had occurred and the presence of significant factors that had contributed to this decline. Results: With a median follow-up of 36 months, the 3-year actuarial survival rate was 93.6%. The 3-year actuarial local control rate was 86.9%. The median time to visual loss after therapy was 18.7 months. The 3-year actuarial rate of visual preservation was 40.5%. Multivariate analysis demonstrated higher macula dose rates (p=0.003) to forecast visual decline. Macula dose rates of 111±11.1 cGy/h were associated with a 50% risk of significant visual loss. Conclusion: Patients in our series treated with 125 I plaque brachytherapy for choroidal melanoma experienced favorable tumor control, but with a measurable incidence of visual decline. Higher dose rates to the macula correlated strongly with poorer posttreatment visual outcome. This information may be valuable in selecting the optimal dose rates to treat choroidal melanomas and to predict the risk of visual decline

    The goal was to assess the changes in visual acuity before and after 6 months of treatment, depending on the dose in risk structures (lens, optic nerve). This is a retrospective study of 19 patients group treated in 2011. The average age of the group was (57.3 ± 12.4) years (31-73 years). The analysis of the studied group did not demonstrate dependence of the tumour presence on gender. Higher prevalence of tumours was observed in the elderly population. Considered relationship of worse diagnosis with higher age (r = 0.39; p = 0.13) we could not prove to be significant due to the small group of patients. The median of melanoma volume was 0.77 cm 3 (0.11 to 1.76 cubic centimetres). The mean dose applied to melanoma was 37.34 Gy (Gy 36.74 to 44.65).

    Full Text Available We report a 7-year-old girl with xeroderma pigmentosum (XP, who presented in our clinic with a large melanoma (35 × 50 × 20 mm, Breslow depth 18 mm in the zygomatic-malar area. Palliative surgery was performed to maintain her residual vision and to reduce the pain caused by the compression of local structures. Because of the limited access of autologous skin grafts in pediatric patients with XP who are severely affected, we opted to use an acellular dermal matrix. There was 100% graft uptake, and the pain due to compression by the tumor was alleviated. This case demonstrates that acellular dermal matrices can be safely and effectively used in oncological facial reconstruction, especially in patients with progressive conditions such as XP.

    Purpose: To determine the relationship between the long-term visual function and the dose and dose rates delivered to critical ocular structures in patients with choroidal melanoma treated with 125 I episcleral plaque radiotherapy. Methods and Materials: From 1987 to 1993, 63 patients underwent 125 I episcleral plaque application for the treatment of choroidal melanoma. Mean tumor height was 4.6 mm (range 1.7-8.3 mm). Plaques utilized were of COMS design. Doses and dose rates at the tumor apex, macula, and optic disc were obtained. Visual acuity data prior to and after plaque application was available for 52 patients. 9 patients were excluded from analysis secondary to co-morbidities or disease progression. 43 records were scored to assess if a decrease in visual acuity of ≥ 2 lines on a standard Snellen eye chart had occurred. Statistical analysis was performed using chi-square tests of significance. Results: Of the 63 total patients, 59 (93.7%) were alive at a median follow-up of 36 months. Local progression occurred in (7(63)) (11.1%). Median dose and dose rate to the tumor apex were 90 Gy and 97.2 cGy/hr, respectively. Of the 43 patients with post-treatment visual acuity analysis, 28 (65.1%) experienced visual loss of ≥ 2 lines on a standard eye chart. Median time to altered visual acuity was 20 months. Median dose and dose rates to the macula in patients with a significant visual loss were 123.3 Gy and 122.5 cGy/hr, respectively, compared with 38 Gy and 51.9 cGy/hr in those without notable visual change. These differences reached statistical significance at a dose and dose rate to the macula of 82.0 Gy (p 125 I plaque brachytherapy for choroidal melanoma experienced favorable tumor control, but with a measurable incidence of decreased visual acuity. Both total dose and dose rates to the macula and optic disc correlated strongly with post-treatment visual outcome.

    To assess the association of baseline tumor size (BTS) with other baseline clinical factors and outcomes in pembrolizumab-treated patients with advanced melanoma in KEYNOTE-001 (NCT01295827). BTS was quantified by adding the sum of the longest dimensions of all measurable baseline target lesions. BTS as a dichotomous and continuous variable was evaluated with other baseline factors using logistic regression for objective response rate (ORR) and Cox regression for overall survival (OS). Nominal P values with no multiplicity adjustment describe the strength of observed associations. Per central review by RECIST v1.1, 583 of 655 patients had baseline measurable disease and were included in this post hoc analysis. Median BTS was 10.2 cm (range, 1-89.5). Larger median BTS was associated with Eastern Cooperative Oncology Group performance status 1, elevated lactate dehydrogenase (LDH), stage M1c disease, and liver metastases (with or without any other sites) (all P ≤ 0.001). In univariate analyses, BTS below the median was associated with higher ORR (44% vs 23%; P BTS below the median remained an independent prognostic marker of OS (P BTS below the median and PD-L1-positive tumors were independently associated with higher ORR and longer OS. BTS is associated with many other baseline clinical factors but is also independently prognostic of survival in pembrolizumab-treated patients with advanced melanoma.

    2012-05-01

    Purpose: To evaluate side effects of hypofractionated stereotactic photon radiotherapy for patients with choroidal melanoma. Patients and Methods: Two hundred and twelve patients with choroidal melanoma unsuitable for ruthenium-106 brachytherapy or local resection were treated stereotactically at the Medical University of Vienna between 1997 and 2007 with a Linac with 6-MV photon beams in five fractions with 10, 12, or 14 Gy per fraction. Examinations for radiogenic side effects were performed at baseline and every 3 months in the first 2 years, then every 6 months until 5 years and then once a year thereafter until 10 years after radiotherapy. Adverse side effects were assessed using slit-lamp examination, funduscopy, gonioscopy, tonometry, and, if necessary, fundus photography and fluorescein angiography. Evaluations of incidence of side effects are based on an actuarial analysis. Results: One hundred and eighty-nine (89.2%) and 168 (79.2%) of the tumors were within 3 mm of the macula and the optic disc, respectively. The five most common radiotherapy side effects were retinopathy and optic neuropathy (114 cases and 107 cases, respectively), cataract development (87 cases), neovascular glaucoma (46 cases), and corneal epithelium defects (41 cases). In total, 33.6%, 38.5%, 51.2%, 75.5%, and 77.6% of the patients were free of any radiation retinopathy, optic neuropathy, cataract, neovascular glaucoma, or corneal epithelium defects 5 years after radiotherapy, respectively. Conclusion: In centrally located choroidal melanoma hypofractionated stereotactic photon radiotherapy shows a low to moderate rate of adverse long-term side effects comparable with those after proton beam radiotherapy. Future fractionation schemes should seek to further reduce adverse side effects rate while maintaining excellent local tumor control.

    The checkpoint inhibitor nivolumab is active in patients with metastatic melanoma who have failed ipilimumab. In this phase I/II study, we assessed nivolumab's safety in 92 ipilimumab-refractory patients with unresectable stage III or IV melanoma, including those who experienced grade 3-4 drug-related toxicity to ipilimumab. We report long-term survival, response duration, and biomarkers in these patients after nivolumab treatment (3 mg/kg) every 2 weeks for 24 weeks, then every 12 weeks for up to 2 years, with or without a multipeptide vaccine. The response rate for ipilimumab-refractory patients was 30% (95% CI, 21%-41%). The median duration of response was 14.6 months, median progression-free survival was 5.3 months, and median overall survival was 20.6 months, when patients were followed up for a median of 16 months. One- and 2-year survival rates were 68.4% and 31.2%, respectively. Ipilimumab-naïve and ipilimumab-refractory patients showed no significant difference in survival. The 21 patients with prior grade 3-4 toxicity to ipilimumab that was managed with steroids tolerated nivolumab well, with 62% (95% CI, 38%-82%) having complete or partial responses or stabilized disease at 24 weeks. High numbers of myeloid-derived suppressor cells (MDSC) were associated with poor survival. Thus, survival and long-term safety were excellent in ipilimumab-refractory patients treated with nivolumab. Prior grade 3-4 immune-related adverse effects from ipilimumab were not indicative of nivolumab toxicities, and patients had a high overall rate of remission or stability at 24 weeks. Prospectively evaluating MDSC numbers before treatment could help assess the expected benefit of nivolumab. ©2016 American Association for Cancer Research.

    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.

    The melanoma originates from the melanocytes, which are embryologically derived from neural crest. The melanoma of choroids in adults is a very common type primary ocular malignancy, where the tyrosine, an immediate precursor common for both melanin and thyroid hormone synthesis is involved. The neurogenic origins of melanoma and medullary thyroid carcinoma have also been shown to have certain common metabolites, receptors and the receptor binding proteins. Several radiolabelled derivatives either in the form of melanin metabolites or melanin binding agents including receptors/ receptor-binding proteins like somatostatin, calcitonin and other monoclonal antibodies, protein receptors (S-100, myelin basic protein, Leu-7, glial fibrillary acidic protein, HMB-45) etc. have been tried to evaluate/diagnose melanoma, staging or post therapeutic effects. However their cost of production, tedious synthetic and radiolabelling processes and the availability of certain cyclotron produced isotopes were not favorable or patient friendly. Moreover post-therapeutic assessments in melanoma patients were not encouraging. Because of the chelating properties of Tc-99m (V) Dimercaptosuccinic acid with Calcium ion, uptake by neurogenic tumors including ocular retinoblastoma, medullary thyroid carcinoma, pituitary adenoma etc has been demonstrated. Since MTC and Melanoma have the common neural crest origin and producing some common metabolites, receptors/receptor proteins and at the same time Tc-99m (V) DMSA was used in pre and post therapeutic assessment of Medullary thyroid carcinoma extensively. We therefore decided to use Tc-99m (v) DMSA for the assessment of melanoma developed in thyrotoxicosis patients who underwent radioiodine therapy more than 15 years back. The DMSA kits were prepared locally and labeled with Tecnetium-99m at pentavalent state. After the quality control each patients were injected a dose of 10mCi of Tc-99m labeled DMSA.The whole body images were taken after two

    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

    Purpose To evaluate a panel of pretreatment clinical and laboratory parameters in metastatic melanoma (MM) in order to verify their impact on response and survival in a single prospective multi-institutional phase III study comparing out-patient chemotherapy (CT) vs bioCT. Methods A total of 176 patients were randomised to receive CT (cisplatin, dacarbazine, optional carmustine) or bioCT (the same CT followed by subcutaneous IL-2 plus intramuscular α-IFN-2b). Pretreatment total leucocytes, lymphocytes, eosinophyls, C-reactive protein (CRP), lactate dehydrogenase (LDH), erytrosedimentation rate (ESR), and fibrinogen were analyzed. Some clinical parameters (performance status, age, sex, and disease site) were also considered. As we found a positive trend for bio-CT with no statistical significance in OR (25.3% vs 20.2%) and OS (11 Mo vs 9.5 Mo), all analyses are stratified by treatment arm. Results In univariate analysis, higher value of lymphocytes percentage (P < .0001), lower value of total leucocytes (P=.005), CRP (P=.003), LHD (P < .0001), ESR (P < .027), fibrinogen (P < .0001), and no liver disease were strongly related to a better survival. In a multivariate analysis, using the Cox proportional hazards model, only fibrinogen (P=.004), LDH (P=.009) and liver disease (P=.04) were found to have an independent role on clinical outcome in metastatic melanoma patients. Conclusion Liver disease and higher LDH and fibrinogen levels had an important impact on survival in MM patients. In particular, fibrinogen has been recently reconsidered both for its determinant role in the host hemostatic system, and for its capability to provide protection against NK and LAK-cell-induced lysis. These observations could have some important implications for therapeutic approaches, in particular when immunological strategies are used. PMID:14690541

    Full Text Available High-dose interferon alfa-2b (IFN-α-2b improves the survival of patients with high-risk melanoma. We aimed to identify baseline peripheral blood biomarkers to predict the outcome of acral melanoma patients treated with IFN-α-2b. Pretreatment baseline parameters and clinical data were assessed in 226 patients with acral melanoma. Relapse-free survival (RFS and overall survival (OS were assessed using the Kaplan-Meier method, and multivariate Cox regression analyses were applied after adjusting for stage, lactate dehydrogenase (LDH, and ulceration. Univariate analysis showed that neutrophil-to-lymphocyte ratio ≥2.35, platelet-to-lymphocyte ratio ≥129, systemic immune-inflammation index (SII ≥615 × 109/l, and elevated LDH were significantly associated with poor RFS and OS. The SII is calculated as follows: platelet count × neutrophil count/lymphocyte count. On multivariate analysis, the SII was associated with RFS [hazard ratio (HR=1.661, 95% confidence interval (CI: 1.066-2.586, P=.025] and OS (HR=2.071, 95% CI: 1.204-3.564, P=.009. Additionally, we developed a novel circulating T-cell immune index (CTII calculated as follows: cytotoxic T lymphocytes/(CD4+ regulatory T cells × CD8+ regulatory T cells. On univariate analysis, the CTII was associated with OS (HR=1.73, 95% CI: 1.01-2.94, P=.044. The SII and CTII might serve as prognostic indicators in acral melanoma patients treated with IFN-α-2b. The indexes are easily obtainable via routine tests in clinical practice.

    We evaluated atypical response patterns and the relationship between overall survival and best overall response measured per immune-related response criteria (irRC) and Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) in patients with advanced melanoma treated with pembrolizumab in the phase Ib KEYNOTE-001 study (clinical trial information: NCT01295827). Patients received pembrolizumab 2 or 10 mg/kg every 2 weeks or every 3 weeks. Atypical responses were identified by using centrally assessed irRC data in patients with ≥ 28 weeks of imaging. Pseudoprogression was defined as ≥ 25% increase in tumor burden at week 12 (early) or any assessment after week 12 (delayed) that was not confirmed as progressive disease at next assessment. Response was assessed centrally per irRC and RECIST v1.1. Of the 655 patients with melanoma enrolled, 327 had ≥ 28 weeks of imaging follow-up. Twenty-four (7%) of these 327 patients had atypical responses (15 [5%] with early pseudoprogression and nine [3%] with delayed pseudoprogression). Of the 592 patients who survived ≥ 12 weeks, 84 (14%) experienced progressive disease per RECIST v1.1 but nonprogressive disease per irRC. Two-year overall survival rates were 77.6% in patients with nonprogressive disease per both criteria (n = 331), 37.5% in patients with progressive disease per RECIST v1.1 but nonprogressive disease per irRC (n = 84), and 17.3% in patients with progressive disease per both criteria (n = 177). Atypical responses were observed in patients with melanoma treated with pembrolizumab. Based on survival analysis, conventional RECIST might underestimate the benefit of pembrolizumab in approximately 15% of patients; modified criteria that permit treatment beyond initial progression per RECIST v1.1 might prevent premature cessation of treatment. © 2016 by American Society of Clinical Oncology.

    The activation of oncogenic Wnt/β-catenin pathway in melanoma contributes to a lack of T-cell infiltration. Whether baseline β-catenin expression in the context of tumour-infiltrating lymphocytes (TILs) and programmed death ligand-1 (PD-L1) overexpression correlates with prognosis of metastatic melanoma patients (MMPs) treated with mitogen-activated protein kinase, MAPK inhibitor (MAPKi) monotherapy, however, has not been fully clarified. Sixty-four pre-treatment formalin-fixed and paraffin embedded melanoma samples from MMP treated with a BRAF inhibitor (n = 39) or BRAF and MEK inhibitors (n = 25) were assessed for presence of β-catenin, PD-L1, cluster of differentiation (CD)8, CD103 and forkhead box protein P3 (FOXP3) expression by immunohistochemistry, and results were correlated with clinical outcome. Quantitative assessment of mRNA transcripts associated with Wnt/β-catenin pathway and immune response was performed in 51 patients. We found an inverse correlation between tumoural β-catenin expression and the level of CD8, CD103 or forkhead box protein P3 (FOXP3) positivity in the tumour microenvironment (TME). By multivariate analysis, PD-L1 <5% (odds ratio, OR 0.12, 95% confidence interval, CI 0.03-0.53, p = 0.005) and the presence of CD8+ T cells (OR 18.27, 95%CI 2.54-131.52, p = 0.004) were significantly associated with a higher probability of response to MAPKi monotherapy. Responding patients showed a significantly increased expression of mRNA transcripts associated with adaptive immunity and antigen presentation. By multivariate analysis, progression-free survival (PFS) (hazards ratio (HR) = 0.25 95%CI 0.10-0.61, p = 0.002) and overall survival (OS) (HR = 0.24 95%CI 0.09-0.67, p = 0.006) were longer in patients with high density of CD8+ T cells and β-catenin <10% than those without CD8+ T cells infiltration and β-catenin ≥10%. Our findings provide evidence that in the context of MAPKi monotherapy, immune subsets in the (TME) and

    Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPNs), but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPNs specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in nine of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events, with the majority of these occurring prior to or within 3 months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPNs and have important clinical consequences for management.

    Metastatic melanoma is characterized by complex genomic alterations, including a high rate of mutations in driver genes and widespread deletions and amplifications encompassing various chromosome regions. Among them, chromosome 7 is frequently gained in BRAF -mutant melanoma, inducing a mutant allele-specific imbalance. Although BRAF amplification is a known mechanism of acquired resistance to therapy with MAPK inhibitors, it is still unclear if BRAF copy-number variation and BRAF mutant allele imbalance at baseline can be associated with response to treatment. In this study, we used a multimodal approach to assess BRAF copy number and mutant allele frequency in pretreatment melanoma samples from 46 patients who received MAPK inhibitor-based therapy, and we analyzed the association with progression-free survival. We found that 65% patients displayed BRAF gains, often supported by chromosome 7 polysomy. In addition, we observed that 64% patients had a balanced BRAF -mutant/wild-type allele ratio, whereas 14% and 23% patients had low and high BRAF mutant allele frequency, respectively. Notably, a significantly higher risk of progression was observed in patients with a diploid BRAF status versus those with BRAF gains [HR, 2.86; 95% confidence interval (CI), 1.29-6.35; P = 0.01] and in patients with low percentage versus those with a balanced BRAF mutant allele percentage (HR, 4.54; 95% CI, 1.33-15.53; P = 0.016). Our data suggest that quantitative analysis of the BRAF gene could be useful to select the melanoma patients who are most likely to benefit from therapy with MAPK inhibitors.

    Full Text Available Treatment of melanoma patients with mRNA electroporated dendritic cells (TriMixDC-MEL stimulates T-cell responses against the presented tumor-associated antigens (TAAs. In the current clinical trials, melanoma patients with systemic metastases are treated, requiring priming and/or expansion of preexisting TAA-specific T cells that are able to migrate to both the skin and internal organs. We monitored the presence of TAA-specific CD8+ T cells infiltrating the skin at sites of intradermal TriMixDC-MEL injection (SKILs and within the circulation of melanoma patients treated in two clinical trials. In 10 out of fourteen (71% patients screened, CD8+ T cells recognizing any of the four TAA presented by TriMixDC-MEL cellular vaccine were found in both compartments. In total, 30 TAA-specific T-cell responses were detected among the SKILs and 29 among peripheral blood T cells, of which 24 in common. A detailed characterization of the antigen specificity of CD8+ T-cell populations in four patients indicates that the majority of the epitopes detected were only recognized by CD8+ T cells derived from either skin biopsies or peripheral blood, indicating that some compartmentalization occurs after TriMix-DC therapy. To conclude, functional TAA-specific CD8+ T cells distribute both to the skin and peripheral blood of patients after TriMixDC-MEL therapy.

  17. Popliteal lymphadenectomy for treating metastatic melanoma: case report

    Directory of Open Access Journals (Sweden)

    Sergio Renato Pais Costa

    Full Text Available CONTEXT: Regional lymph node involvement in patients with malignant melanomas has been associated with poor prognosis. In-transit metastases also lead to poor long-term survival. Whereas for nodal disease only regional lymphadenectomy offers adequate locoregional control, for in-transit metastasis both local excision and isolated limb perfusion with chemotherapy plus tumor necrosis factor-alpha can be used for disease control. In cases of tumors located in the distal region of the legs, the lymphatic dissemination most commonly observed is to the inguinal chain. Consequently, therapeutic inguinal lymphadenectomy or even selective lymphadenectomy (sentinel lymph node biopsy have been recommended. On the other hand, involvement of the popliteal chain is very rare. When this occurs, popliteal lymphadenectomy should be indicated. Local excision may be the logical approach for a few small in-transit metastases because of the low morbidity in this procedure, when compared with isolated limb perfusion. CASE REPORT: A case of melanoma of the heel with popliteal chain involvement and in-transit metastases is presented. This was treated by means of regional lymphadenectomy plus in-transit metastases excision, with a good postoperative course.

    The management of melanoma is directly related to Breslow's depth. Biopsying melanomas in a fashion that transects the deep margin precludes an accurate measurement of the true depth. To examine the prognosis of melanomas transected along the deep margins, as well as cases where no residual melanoma was seen on re-excision after transection. Records from a cohort of patients at one institution were examined from 1996 through 2007. Patients were considered to have "transected" melanomas if tumor cells were present on the deep margin of the biopsy. Overall survival was determined. Seven hundred fourteen patients were examined. 171 (24%) of all melanomas were transected. 101(59%) of those lacked tumor cells on re-excision. Patients with transected melanomas were older (OR = 1.03, p < .001), and had higher Breslow's depths (OR = 1.21, p < .001) than those without transected tumors. Those with no residual melanoma after transection were younger (OR = 0.98, p = .010) and more likely to have no lymph node involvement (OR = 2.23, p = .037). Neither transection (p = .760), nor lack of residual melanoma on re-excision after transection (p = .793) influenced survival. A high number of melanomas are transected at diagnosis, many of which lack visible tumor. The original Breslow's depth of transected melanomas without residual tumor on re-excision accurately predicts survival and prognosis. © 2013 by the American Society for Dermatologic Surgery, Inc.

    Esophageal melanomas correspond to 0.1 to 0.2% of esophageal tumors. We report two patients with the disease. The first patient is a 51 year-old woman pre-sentingwith dysphagia and weight loss. An upper gastrointestinal endoscopy showed a polypoid ulcerated lesion in the middle third of the esophagus. The pathological study of the biopsy disclosed a malignant melanoma. The patient was subjected to an esophagectomy with a satisfactory postoperative evolution. Four months later, liver metastases were detected and the patient died eleven months after the operation. The second patient is a 59 year-old mole that consulted by dysphagia. An endoscopy showed a pigmented esophageal lesion whose pathological diagnosis was a malignant melanoma. The patient was subjected to an esophagectomy and sixteen months after surgery there was no evidence of relaps

    We treated four cases of facial melanoma by BNCT with 10 B-paraboronophenylalanine · fructose complex (BPA). The patients received 180 to 200 mg BPA/kg-BW intravenously for 3 to 5 hours. One to two hours after the end of BPA administration, they were irradiated with a thermal neutron beam at the Kyoto University Reactor (KUR). The local control of the tumors was good and complete regression was achieved in all cases. The acute and subacute skin reactions ranged from dry desquamation to erosion and were within tolerable limits. After 2 to 3 months, the skin recovered from damage with slight pigmentation or depigmentation and without serious functional or cosmetic problems. Our results indicate BNCT of facial melanoma is promising not only for tumor cure but also for good QOL of the patients, although surgery is the standard and first choice for the treatment of malignant melanoma.

    New advanced melanoma therapies are associated with improved survival; however, quality of survivorship, particularly psychosocial outcomes, for patients overall and those treated with newer therapies is unclear. Synthesize qualitative and quantitative evidence about psychosocial outcomes for advanced (stage III/IV) melanoma patients. Five databases were searched (01/01/1980 to 31/01/2016). Inclusion criteria were as follows: advanced melanoma patients or sub-group analysis; assessed psychosocial outcomes; and English language. Fifty-two studies met review criteria (4 qualitative, 48 quantitative). Trials comprise mostly medical not psychosocial interventions, with psychosocial outcomes assessed within broader quality of life measures. Patients receiving chemotherapy or IFN-alpha showed decreased emotional and social function and increased distress. Five trials of newer therapies appeared to show improvements in emotional and social function. Descriptive studies suggest that patients with advanced, versus localized disease, had decreased emotional and social function and increased distress. Contributors to distress were largely unexplored, and no clear framework described coping/adjustment trajectories. Patients with advanced versus localized disease had more supportive care needs, particularly amount, quality, and timing of melanoma-related information, communication with and emotional support from clinicians. Limitations included: lack of theoretical underpinnings guiding study design; inconsistent measurement approaches; small sample sizes; non-representative sampling; and cross-sectional design. Quality trial evidence is needed to clarify the impact of treatment innovations for advanced melanoma on patients' psychosocial well-being. Survivorship research and subsequent translation of that knowledge into programs and services currently lags behind gains in the medical treatment of advanced melanoma, a troubling circumstance that requires immediate and focused

  5. Circulating tumor cells in melanoma patients.

    Directory of Open Access Journals (Sweden)

    Gary A Clawson

    Full Text Available Circulating tumor cells (CTCs are of recognized importance for diagnosis and prognosis of cancer patients. With melanoma, most studies do not show any clear relationship between CTC levels and stage of disease. Here, CTCs were enriched (∼400X from blood of melanoma patients using a simple centrifugation device (OncoQuick, and 4 melanocyte target RNAs (TYR, MLANA, MITF, and MIF were quantified using QPCR. Approximately one-third of melanoma patients had elevated MIF and MLANA transcripts (p<0.0001 and p<0.001, respectively compared with healthy controls. In contrast, healthy controls had uniformly higher levels of TYR and MITF than melanoma patients (p<0.0001. There was a marked shift of leukocytes into the CTC-enriched fractions (a 430% increase in RNA recovery, p<0.001, and no relationship between CTC levels and stage of disease was found. CTCs were captured on microfabricated filters and cultured. Captured melanoma CTCs were large cells, and consisted of 2 subpopulations, based on immunoreactivity. One subpopulation (∼50% stained for both pan-cytokeratin (KRT markers and the common leukocyte marker CD-45, whereas the second subpopulation stained for only KRT. Since similar cells are described in many cancers, we also examined blood from colorectal and pancreatic cancer patients. We observed analogous results, with most captured CTCs staining for both CD-45/KRT markers (and for the monocyte differentiation marker CD-14. Our results suggest that immature melanocyte-related cells (expressing TYR and MITF RNA may circulate in healthy controls, although they are not readily detectable without considerable enrichment. Further, as early-stage melanomas develop, immature melanocyte migration into the blood is somehow curtailed, whereas a significant proportion of patients develop elevated CTC levels (based on MIF and MLANA RNAs. The nature of the captured CTCs is consistent with literature describing leukocyte/macrophage-tumor cell fusion hybrids

    One hundred forty-one liver scans, 137 brain scans, and 112 bone scans were performed in 192 patients with clinical Stage 1 melanoma. One liver scan was interpreted as abnormal; liver biopsy of that patient showed no metastasis. There were 11 suggestive liver scans; three of the patients with suggestive liver scans had negative liver biopsies. The remaining eight patients were followed from 4 to 6 years and none of those patients developed clinical evidence of hepatic metastases. All of the brain scans were normal. Five patients had suggestive bone scans and none of those patients had manifested symptoms of osseous metastases with a follow-up of 2 to 4.5 years. This study demonstrates that the use of preoperative liver, brain and bone scan in the evaluation of patients with clinical Stage 1 melanoma is virtually unproductive

    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.

    Sarcoidosis is a systemic inflammatory disease characterized by the development of noncaseating granulomas in multiple organ systems. Many hematologic malignancies and solid tumors, including melanoma, have been associated with sarcoidosis. We describe the clinical and pathologic findings of a 54-year-old man with melanoma-associated sarcoidosis. In addition, we not only review the literature describing characteristics of other melanoma patients with sarcoidosis, but also the features of melanoma patients with antineoplastic therapy-associated sarcoidosis. Sarcoidosis has been described in 80 melanoma patients; sufficient information for analysis was provided in 39 of these individuals. In 43.6% of individuals (17 out of 39), sarcoidosis was directly associated with melanoma; in 56.4% of oncologic patients (22 out of 39), sarcoidosis was induced by antineoplastic therapy that had been administered for the treatment of their metastatic melanoma. The discovery of melanoma preceded the development of sarcoidosis in 12 of the 17 (70.5%) individuals who did not receive systemic treatment. Pulmonary and/or cutaneous manifestations of sarcoidosis were common among both groups of patients. Most patients did not require treatment for sarcoidosis. Melanoma patients—either following antineoplastic therapy or without systemic treatment—may be at an increased risk to develop sarcoidosis. In antineoplastic therapy naive melanoma patients, a common etiologic factor—such as exposure to ultraviolet light—may play a role in their developing melanoma and sarcoidosis.

    A 77-year-old male patient with malignant melanoma was treated by fast neutron therapy and immunotherapy. Total dose of fast neutron applied to the primary lesion was 1905 cGy per 21 fractionation for 46 days. For adoptive immunotherapy, lymphocytes were collected from the peripheral blood drawn from the patient 2 days after the injection of cyclophosphamide. T cells were further purified by passing the lymphocytes through nylon wool. Cytotoxic T cells were induced by incubating the T cells mixed with allogeneic malignant melanoma cells and a small number of patient's adherent cells, and activated with recombinant interleukin-2 (γ IL-2). Our patient and the patient from whom stimulating melanoma cells were derived shared A locous 24 and B locous 51 of MHC class I antigens in common. Thus prepared cytotoxic T cells were inoculated to the patient via the maxillary artery, 3 to 4 times a week for one month. Total amount of cells transferred was 5.6 x 10 8 (97% lymphocytes). Primary lesion reduced markedly by the therapies. During adoptive immunotherapy, increase in natural killer cells and decrease in both suppressor/inducer T-cells and macrophages were observed. However, lung metastases appeared 3 months after adoptive immunotherapy. While the nonspecific immunotherapy (OK-432 injection) was being conducted thereafter, growth of the metastatic lesions of the lung was kept gentle but became obvious after the suspension of the treatment.

    Dacarbazine (DTIC) is a DNA-methylating drug used in the treatment of malignant melanoma. Among the DNA dducts induced by DTIC are N7-methylguanine (N7-meG) and O6-methylguamne (O6-meG). The latter adduct, in particular, may be important in the mutagenic as well as the cytotoxic activity of DTIC.

    Three dogs were investigated for chronic unilateral nasal discharge. In all cases CT imaging showed an intranasal mass causing turbinate lysis and no evidence of metastasis. Cytology in cases 1 (a 14-year-old neutered male crossbreed dog) and 2 (a five-year-old neutered male German Shepherd dog) demonstrated a pleomorphic cell population with variable intracellular pigment suspicious of melanocytic neoplasia. Histopathology with immunohistochemistry (Melan-A and vimentin, plus PNL-2 in one case) confirmed the diagnosis of melanoma in all dogs. All dogs were treated with megavoltage radiotherapy using linear accelerators. Cases 1 and 3 (a nine-year-old neutered female beagle dog) received a hypofractionated (4 × 8 Gy) protocol and case 2 received a definitive (12 × 4 Gy) protocol. Complete remission was demonstrated on repeat CT scan five months after diagnosis in case 1 and seven months in case 2. Stable disease was documented on CT at four months for case 3; however, clinical signs in this dog remained controlled for 10 months in total. Case 1 died of unrelated causes five months after diagnosis, case 2 was euthanased due to the development of seizures 13 months after diagnosis, and case 3 was lost to follow-up 12 months after diagnosis. Melanoma should be considered as a rare differential diagnosis for primary nasal neoplasia in the dog and radiation therapy can be used as effective local therapy.

    2008-01-01

    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

    Full Text Available Summary: Tumor-sequencing studies have revealed the widespread genetic diversity of melanoma. Sequencing of 108 genes previously implicated in melanomagenesis was performed on 462 patient-derived xenografts (PDXs, cell lines, and tumors to identify mutational and copy number aberrations. Samples came from 371 unique individuals: 263 were naive to treatment, and 108 were previously treated with targeted therapy (34, immunotherapy (54, or both (20. Models of all previously reported major melanoma subtypes (BRAF, NRAS, NF1, KIT, and WT/WT/WT were identified. Multiple minor melanoma subtypes were also recapitulated, including melanomas with multiple activating mutations in the MAPK-signaling pathway and chromatin-remodeling gene mutations. These well-characterized melanoma PDXs and cell lines can be used not only as reagents for a large array of biological studies but also as pre-clinical models to facilitate drug development. : Garman et al. have characterized melanoma PDXs and cell lines described in Krepler et al.

    The radiotherapy efficiency is still undervalued in the therapeutic taking charge of the malignant melanoma. Our series with its heterogeneity has authorized an only mono factorial analysis. The data in literature and our personal experience give a better efficiency of the strong unitary doses in term of local control. The accuracy of irradiation must allow to reduce the importance of after-effects that can be necessary to the local control and then to the survival. for the future, an increasing of of the applied unitary doses, by taking into account the localisation, the tumoral volume and the therapeutic objective, would allow to improve the efficiency of this treatment. In The particular indication of inoperable Dubreuilh melanosis, it could be an alternative to the surgery. The results of a complementary radiotherapy, after a radical surgery of secondary localisation are very encouraging. Its contribution in adjuvant treatment of recurrence or primitive lesions with high risks would deserve to be evaluated in the frame of well defined and randomized tests. (N.C.)

    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.

    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 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.

  1. Treatment with Ipilimumab: A Case Report of Complete Response in a Metastatic Malignant Melanoma Patient

    Directory of Open Access Journals (Sweden)

    Alfredo Addeo

    2013-05-01

    Full Text Available Introduction: Over the past year, 3 agents have been approved for the treatment of melanoma by the Food and Drug Administration. These include pegylated interferon α-2b for stage III melanoma, vemurafenib for unresectable or metastatic melanoma with BRAF V600E mutation, and ipilimumab for unresectable or metastatic melanoma. Case Presentation: We present here the case of a 65-year-old Caucasian male diagnosed with advanced melanoma in April 2011 and treated with ipilimumab (Yervoy®, a monoclonal antibody targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4, as second-line treatment after progression with dacarbazine, for (wild-type BRAF metastatic melanoma. The patient was referred to us for several painful lumps on his right arm. A biopsy of one of them revealed melanoma. CT and PET scans did not show any other lesions or a primary site. The patient was started on first-line chemotherapy with dacarbazine 850 mg/m2 on day 1, every 3 weeks. After 3 cycles, the patient showed disease progression with an increase in size of the skin metastasis. Second-line treatment was started with ipilimumab 3 mg/kg on day 1, every 3 weeks. At the end of the treatment, after 4 cycles, we documented a complete clinical response with total resolution of the skin metastasis. At the time of writing this paper, our patient had finished his treatment more than 9 months earlier and is still in complete remission. Conclusion: This is a paradigmatic case where, despite extensive metastatic disease, treatment with ipilimumab has confirmed its efficacy. It is still an open question why only a minority of patients have such a remarkable response, and further trials are warranted to address this important question.

    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.

    Full Text Available 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.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.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.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.

    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.

    The risk of melanoma and hematologic cancers in patients with psoriasis is controversial. We sought to assess the risk of melanoma and hematologic cancers in patients with psoriasis, and the association with different treatments. We used case-control and retrospective cohort designs to determine melanoma or hematologic cancer risk in patients with psoriasis. Risk with treatment type was assessed using Fisher exact test. Patients with psoriasis had 1.53 times greater risk of developing a malignancy compared with patients without psoriasis (P < .01). There were no significant differences in malignancy risk among patients treated with topicals, phototherapy, systemics, or biologic agents. Patients with psoriasis and malignancy did not have significantly worse survival than patients without psoriasis. It is possible that patients developed malignancy subsequent to the follow-up time included in the study. Patients with psoriasis may experience an elevated risk of melanoma and hematologic cancers, compared with the general population. The risk is not increased by systemic or biologic psoriasis therapies. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

  6. Clinical benefit from ipilimumab therapy in melanoma patients may be associated with serum CTLA4 levels

    2014-05-01

    Full Text Available Stage IV metastatic melanoma patients historically have a poor prognosis with 5-10% 5-year survival. Ipilimumab, a monoclonal antibody against cytotoxic T-lymphocyte antigen 4 (CTLA4, is one of the first treatments to provide beneficial durable responses in advanced melanoma. However, less than 25% of those treated benefit, treatment is expensive, and side effects can be fatal. Since soluble (s CTLA4 may mediate inhibitory effects previously ascribed to the membrane-bound isoform (mCTLA4, we hypothesized patients benefiting from ipilimumab have higher serum levels of sCTLA4. We found that higher sCTLA4 levels correlated both with response and improved survival in patients treated with ipilimumab in a small patient cohort (patients with (n=9 and without (n=5 clinical benefit. sCTLA4 levels were statistically higher in ipilimumab-treated patients with response to ipilimumab. In contrast, sCTLA4 levels did not correlate with survival in patients who did not receive ipilimumab (n=11. These preliminary observations provide a previously unrecognized link between serum sCTLA-4 levels and response to ipilimumab as well as to improved survival in ipilimumab-treated melanoma patients and a potential mechanism by which ipilimumab functions.

    Full Text Available Immunotherapy for melanoma includes adoptive cell therapy with autologous tumor-infiltrating lymphocytes (TILs. This monocenter retrospective study was undertaken to evaluate the efficacy and safety of this treatment of patients with advanced melanoma. All advanced melanoma patients treated with TILs using the same TIL expansion methodology and same treatment interleukin-2 (IL-2 regimen between 2009 and 2012 were included. After sterile intralesional excision of a cutaneous or subcutaneous metastasis, TILs were produced according to a previously described method and then infused into the patient who also received a complementary subcutaneous IL-2 regimen. Nine women and 1 man were treated for unresectable stage IIIC (n=4 or IV (n=6 melanoma. All but 1 patient with unresectable stage III melanoma (1st line had received at least 2 previous treatments, including anti-CTLA-4 antibody for 4. The number of TILs infused ranged from 0.23 × 109 to 22.9 × 109. Regarding safety, no serious adverse effect was reported. Therapeutic responses included a complete remission, a partial remission, 2 stabilizations, and 6 progressions. Among these 4 patients with clinical benefit, 1 is still alive with 9 years of follow-up and 1 died from another cause after 8 years of follow-up. Notably, patients treated with high percentages of CD4 + CD25 + CD127lowFoxp3+ T cells among their TILs had significantly shorter OS. The therapeutic effect of combining TILs with new immunotherapies needs further investigation.

    Blood circulating melanoma cells may be important for the spread of the disease. The current methods are not sensitive in detecting micro metastases. Tyrosinase mRNA can be detected in peripheral blood by a molecular test. As tyrosinase is expressed only in melanocytes and melanocytes normally do not circulate in the blood, the test may prove reliable in detecting circulating melanoma cells. we used a reverse-transcription polymerase chain reaction (RT-PCR) detecting tyrosinase mRNA in the blood. A prospective investigation in melanoma patients undergoing surgery was conducted; follow-up duration was 12 months. University Department Laboratory and Melanoma Clinic of a Tertiary Hospital. a total of 27 Greek patients with a diagnosis of malignant melanoma at different stages of the disease; 12 months follow-up after surgery. Samples form 12 healthy volunteers and 13 patients with chronic myelogenous leukemia served as controls. none. none. We detected mRNA tyrosinase in the peripheral blood in 16 out of 27 melanoma patients studied. No tyrosinase mRNA was detected in any of the 25 samples from the controls. Two of the 16 positive cases developed a metastasis within the next 12 months following testing. The other 14 positive cases remain metastasis free for this period, as also did the test negative cases. Detection of blood circulating melanoma cells by a RT-PCR technique, may be helpful in defining melanoma patients who are at risk for the spread of the disease.

    Median survival of metastatic malignant melanoma is 6.0 to 7.5 months, with a 5-year survival of approximately 6.0%. Although long-term complete remissions are rare, few reports describe cases after chemotherapy. Fifty-three patients with metastatic melanoma were treated with Cystemustine, a chloroethyl nitrosourea (CENU) (60 or 90 mg/m2). We describe 5 cases, presenting with complete response with long-term disease-free survival of long-term remission of 14, 12, 9, 7 and 6 years after Cystemustine therapy alone. Long-term survival has already been described in literature, but in all cases they have been obtained after chemotherapy associated with or followed by surgery. But despite these noteworthy and encouraging but also rare results, it appears essential to increase Cystemustine efficiency.

    Tumor cells killed by radiation therapy (RT) are a potentially good source of antigens for dendritic cell (DC) uptake and presentation to T-cells. RT upregulates cell death receptors such as Fas/CD95 and MHC-I, induces the expression of co-stimulatory molecules on tumor cells, and promotes production of pro-inflammatory cytokines. High-dose interleukin-2 (HD-IL-2) bolus has been shown to obtain objective response rates ranging from 15% to 17% in patients with metastatic melanoma or renal cell carcinoma (RCC), with 6% to 8% of cases experiencing a durable complete response. However, HD-IL-2 is also associated with severe side-effects; if it is to remain a component of the curative treatment strategy in patients with metastatic melanoma or RCC, its therapeutic efficacy must be improved and patients who are most likely to benefit from treatment must be identified a priori. We designed a clinical study combining immunomodulating RT and HD-IL-2 to evaluate their clinical and immunological efficacy and to explore the predictive and prognostic value of 1) tumor-specific immune response and 2) serum levels of proangiogenic cytokines. The primary endpoint of this proof-of-principle phase II study is immune response. Secondary endpoints are the identification of biomarkers potentially predictive of response, toxicity, response rate and overall survival. Three daily doses of booster radiotherapy (XRT) at 6-12 Gy will be administered to at least one metastatic field on days -3 to -1 before the first and third cycle. Treatment with IL-2 (dose 18 MIU/m2/day by continuous IV infusion for 72 hours) will start on day +1 and will be repeated every 3 weeks for up to 4 cycles and then every 4 weeks for a further 2 cycles. Immune response against tumor antigens expressed by melanoma and/or RCC will be evaluated during treatment.

    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.

    Full Text Available On the basis of remarkable antitumor activity, programmed death receptor-1 (PD-1 inhibitors pembrolizumab and nivolumab were approved for the treatment of advanced melanoma in the second-line setting following progression on either CTLA-4 inhibitor ipilimumab or BRAF/MEK inhibitors (for BRAF mutated melanoma. Given hypothesized risk of triggering exacerbations of autoimmune diseases and/or chronic viral infections, clinical trials (including regulatory studies evaluating checkpoint blocking antibodies PD-1 and CTLA-4 have excluded patients with autoimmune diseases, chronic hepatitis B/C virus (HBV/HCV, and/or human immunodeficiency virus (HIV infections. Herein, we describe two patients with advanced melanoma and concomitant HCV/HIV infections treated with PD-1 inhibitor pembrolizumab. Patient 2 with HIV/HCV coinfection progressed after 2 doses of pembrolizumab. Patient 1 who had HCV alone was treated with pembrolizumab with initial partial response. HCV viral load remained stable after 9 cycles of pembrolizumab following which 12-week course of HCV-directed therapy was commenced, resulting in prompt reduction of HCV viral load below detectable levels. Response is ongoing and HCV viral load remains undetectable. In both patients, no significant toxicities were observed when pembrolizumab was initiated. We argue for the further investigation of checkpoint inhibition in cancer patients with underlying chronic viral infections in the context of carefully designed clinical trials.

    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.

    Programmed cell death 1 (PD-1) is an inhibitory receptor expressed by activated T cells that downmodulates effector functions and limits the generation of immune memory. PD-1 blockade can mediate tumor regression in a substantial proportion of patients with melanoma, but it is not known whether this is associated with extended survival or maintenance of response after treatment is discontinued. Patients with advanced melanoma (N = 107) enrolled between 2008 and 2012 received intravenous nivolumab in an outpatient setting every 2 weeks for up to 96 weeks and were observed for overall survival, long-term safety, and response duration after treatment discontinuation. Median overall survival in nivolumab-treated patients (62% with two to five prior systemic therapies) was 16.8 months, and 1- and 2-year survival rates were 62% and 43%, respectively. Among 33 patients with objective tumor regressions (31%), the Kaplan-Meier estimated median response duration was 2 years. Seventeen patients discontinued therapy for reasons other than disease progression, and 12 (71%) of 17 maintained responses off-therapy for at least 16 weeks (range, 16 to 56+ weeks). Objective response and toxicity rates were similar to those reported previously; in an extended analysis of all 306 patients treated on this trial (including those with other cancer types), exposure-adjusted toxicity rates were not cumulative. Overall survival following nivolumab treatment in patients with advanced treatment-refractory melanoma compares favorably with that in literature studies of similar patient populations. Responses were durable and persisted after drug discontinuation. Long-term safety was acceptable. Ongoing randomized clinical trials will further assess the impact of nivolumab therapy on overall survival in patients with metastatic melanoma.

    Purpose To evaluate the effects BRAF inhibition on the tumor microenvironment in patients with metastatic melanoma. Experimental Design Thirty-five biopsies were collected from 16 patients with metastatic melanoma pretreatment (day 0) and at 10-14 days after initiation of treatment with either BRAF inhibitor alone (vemurafenib) or BRAF + MEK inhibition (dabrafenib + trametinib), and were also taken at time of progression. Biopsies were analyzed for melanoma antigens, T cell markers, and immunomodulatory cytokines. Results Treatment with either BRAF inhibitor alone or BRAF + MEK inhibitor was associated with an increased expression of melanoma antigens and an increase in CD8+ T cell infiltrate. This was also associated with a decrease in immunosuppressive cytokines (IL-6 & IL-8) and an increase in markers of T cell cytotoxicity. Interestingly, expression of exhaustion markers TIM-3 and PD1 and the immunosuppressive ligand PDL1 were increased on treatment. A decrease in melanoma antigen expression and CD8 T cell infiltrate was noted at time of progression on BRAF inhibitor alone, and was reversed with combined BRAF and MEK inhibition. Conclusions Together, this data suggests that treatment with BRAF inhibition enhances melanoma antigen expression and facilitates T cell cytotoxicity and a more favorable tumor microenvironment, providing support for potential synergy of BRAF-targeted therapy and immunotherapy. Interestingly, markers of T cell exhaustion and the immunosuppressive ligand PDL1 are also increased with BRAF inhibition, further implying that immune checkpoint blockade may be critical in augmenting responses to BRAF-targeted therapy in patients with melanoma.

    Summary: Metastases from uveal melanoma are often confined to the liver. Palliative hepatic chemoembolization has been considered to be a reasonable treatment approach. We enrolled 14 patients with hepatic metastases from uveal melanoma into a pilot trial of transarterial chemoembolization (TACE). All patients received additional systemic immuno-chemotherapy or best supportive care. In 31 procedures 100 mg/m{sup 2} of cisplatine was continuously infused by means of a power injector preceding embolization by manual injection of polyvinyl alcohol particles. In three procedures cisplatine was replaced by 200 mg/m{sup 2} carboplatine because of increased serum creatinine levels. Tumor response was evaluated using RECIST criteria. Fourteen patients received 34 TACE's (mean: 2.4 treatments). Eight patients (57%) achieved partial response (PR), four patients (29%) had stable disease and two patients (14%) tumor progression. Median time to progression was 8.5 months (5-35 months). Median survival after first TACE was 14.5 months in responders compared to 10 months in non-responders (p = 0.18, not significant) and 11.5 months (3-69 months) in all patients. In seven patients with metastases occupying less than 25% of liver volume median survival was 17 months compared to 11 months in seven patients with tumor involvement of more than 25% (p = 0.02) with partial response rate of 86% and 29%, respectively. TACE of liver metastases from uveal melanoma is well tolerated and may prolong survival in patients with limited tumor extension.

    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.

    Full Text Available Rachel K Voss,1 Tessa N Woods,1 Kate D Cromwell,1 Kelly C Nelson,2 Janice N Cormier1 1Department of Surgical Oncology, 2Department of Dermatology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Abstract: Patients with thin, low-risk melanomas have an excellent long-term prognosis and higher quality of life than those who are diagnosed at later stages. From an economic standpoint, treatment of early stage melanoma consumes a fraction of the health care resources needed to treat advanced disease. Consequently, early diagnosis of melanoma is in the best interest of patients, payers, and health care systems. This review describes strategies to ensure that patients receive an early diagnosis through interventions ranging from better utilization of primary care clinics, to in vivo diagnostic technologies, to new “apps” available in the market. Strategies for screening those at high risk due to age, male sex, skin type, nevi, genetic mutations, or family history are discussed. Despite progress in identifying those at high risk for melanoma, there remains a lack of general consensus worldwide for best screening practices. Strategies to ensure early diagnosis of recurrent disease in those with a prior melanoma diagnosis are also reviewed. Variations in recurrence surveillance practices by type of provider and country are featured, with evidence demonstrating that various imaging studies, including ultrasound, computed tomography, positron emission tomography, and magnetic resonance imaging, provide only minimal gains in life expectancy, even for those with more advanced (stage III disease. Because the majority of melanomas are attributable to ultraviolet radiation in the form of sunlight, primary prevention strategies, including sunscreen use and behavioral interventions, are reviewed. Recent international government regulation of tanning beds is described, as well as issues surrounding the continued use artificial ultraviolet

    This study will show a comparison of two groups of patients with uveal melanoma; one group with multiple primary cancer, and a second group with no identifiable second cancer, in terms of education and occupation. Study concerns 240 patients, who were isolated from patients being treated with uveal melanoma at the Department of Ophthalmology and Ocular Oncology Jagiellonian University Medical College in the period from 1998 to 2007. On the basis of medical history and medical records 97 patients were diagnosed with the one or more independent primary cancers. These patients were subjected to comparative analysis with a group of 143 patients with uveal melanoma as a control group. Analyzing the impact of education on the recognition of multiple primary cancer, there were significantly more frequent diagnoses of second primary cancers among patients with secondary and higher education than among those who had primary and vocational education. Among the obtained data on patients in the study group, the largest occupational group (according to the ISCO-88 (COM)) constituted "professionals". In the control group prevailed "craft and related trades workers". The results suggest the great importance of knowledge about risk factors for the development of cancer among patients with uveal melanoma and the ensuing more scrupulous search for succesive primary neoplasm and indicate the neccesity of organizing broad prophylactic actions. uveal melanoma, multiple primary cancer.

    Since 2003 we have conducted BNCT clinical trials on melanomas at the Kyoto University Research Reactor (KUR) and Japan Research Reactor No.4 (JRR-4). We report 4 patients given BNCT for malignant melanomas: 2 with superficial spreading types on the heel, 1 with mucosal melanoma in the nasal cavity, and 1 with a melanoma on the vulva and in the vagina. The two cutaneous melanomas and the nasal cavity mucosal melanoma showed a complete response (CR) by 6 months after BNCT. The residual melanoma showed a partial response (PR) by 3 months after treatment and no regrowth since then. Although two patients experienced normal-tissue damage that exceeded the tolerance level, all the participants were cured within a few months of treatment. BNCT was shown to be a promising treatment for mucosal, as well as for cutaneous, melanomas. (author)

    Full Text Available Brendon J Coventry, Dominique Baume, Carrie Lilly Discipline of Surgery, Royal Adelaide Hospital, University of Adelaide, Adelaide, SA, Australia Background: Patients with advanced metastatic melanoma are often confronted with little prospect of medium- to longer-term survival by any currently available therapeutic means. However, most clinicians are aware of exceptional cases where survival defies the notion of futility. Prolonged survival from immunotherapies, including interleukin-2, vaccines and antibodies to cytotoxic lymphocyte antigen-4, and programmed death-1 receptor inhibitory monoclonal antibody, implies a role for immune system modulation. We aimed to identify cases where exceptional survival from advanced melanoma occurred prior to recent novel therapies to facilitate better understanding of this phenomenon. Methods: Cases of long-term survival of ≥3 years' duration (from diagnosis of metastatic disease were identified from the database of one clinician; these cases were treated before the availability of newer immunotherapies, and they were documented and examined. A literature search for reported outcome measures from published studies using older and recent therapies for advanced melanoma was conducted to enable the comparison of data. Results: Eighteen cases were identified that identified survival of ≥3 years' duration from metastatic disease (12 American Joint Committee on Cancer [AJCC] Stage IV cases; six AJCC III cases diagnosis. These were assessed and reported to detail the clinical course. Standard clinical prognostication methods predicted high risk of early mortality in those patients. No identifiable differences could be detected between these and other patients with similar patterns of disease. At evaluation, 17 patients (94% had survived ≥5 years, and eleven patients (61% had survived ≥10 years (range: 3–15 years. The median survival duration with metastatic disease was 11 years; 15 remained alive and three

    Full Text Available BACKGROUND: Patients with metastatic melanoma have a very unfavorable prognosis with few therapeutic options. Based on previous promising experiences within a clinical trial involving carboplatin and paclitaxel a series of advanced metastatic melanoma patients were treated with this combination. METHODS: Data of all patients with cutaneous metastatic melanoma treated with carboplatin and paclitaxel (CP at our institution between October 2005 and December 2007 were retrospectively evaluated. For all patients a once-every-3-weeks dose-intensified regimen was used. Overall and progression free survival were calculated using the method of Kaplan and Meier. Tumour response was evaluated according to RECIST criteria. RESULTS: 61 patients with cutaneous metastatic melanoma were treated with CP. 20 patients (85% M1c received CP as first-line treatment, 41 patients (90.2% M1c had received at least one prior systemic therapy for metastatic disease. Main toxicities were myelosuppression, fatigue and peripheral neuropathy. Partial responses were noted in 4.9% of patients, stable disease in 23% of patients. No complete response was observed. Median progression free survival was 10 weeks. Median overall survival was 31 weeks. Response, progression-free and overall survival were equivalent in first- and second-line patients. 60 patients of 61 died after a median follow up of 7 months. Median overall survival differed for patients with controlled disease (PR+SD (49 weeks compared to patients with progressive disease (18 weeks. CONCLUSIONS: Among patients with metastatic melanoma a subgroup achieved disease control under CP therapy which may be associated with a survival benefit. This potential advantage has to be weighed against considerable toxicity. Since response rates and survival were not improved in previously untreated patients compared to pretreated patients, CP should thus not be applied as first-line treatment.

    Purpose: To find a dose-volume effect for inhomogeneous irradiated lacrimal glands. Methods and Materials: Between 1999 and 2006, 72 patients (42 men and 30 women) were treated with fractionated stereotactic radiotherapy in a prospective, nonrandomized clinical trial (median follow-up, 32 months). A total dose of 50 Gy was given on 5 consecutive days. The mean of all Schirmer test results obtained ≥6 months after treatment was correlated with the radiation dose delivered to the lacrimal gland. Also, the appearance of dry eye syndrome (DES) was related to the lacrimal gland dose distribution. Results: Of the 72 patients, 17 developed a late Schirmer value <10 mm; 9 patients developed DES. A statistically significant relationship was found between the received median dose in the lacrimal gland vs. reduced tear production (p = 0.000) and vs. the appearance of DES (p = 0.003), respectively. A median dose of 7 Gy/fraction to the lacrimal gland caused a 50% risk of low Schirmer results. A median dose of 10 Gy resulted in a 50% probability of DES. Conclusion: We found a clear dose-volume relationship for irradiated lacrimal glands with regard to reduced tear production and the appearance of DES.

    Purpose: The Collaborative Ocular Melanoma Study (COMS) established iodine-125 plaque brachytherapy as an accepted standard treatment for medium-size choroidal melanoma. In the COMS, the prescription dose was 85 Gy. This is a retrospective review of our outcomes in patients treated with lower doses than those used in the COMS. Methods and Materials: From 1990 to 2004, 62 patients were treated with iodine-125 plaque brachytherapy for choroidal melanoma. COMS eye plaques were used with dose prescribed to the apex of the tumor. The median and average dose rates at the tumor apex were 63.5 cGy/h and 62.7 cGy/h, respectively. The median and average total doses were 63.0 Gy and 62.5 Gy (range, 56-69 Gy), respectively. The median and mean durations of implant were 100.0 hours and 101.1 hours (range, 71-165 hours). Results: Median follow-up time was 58.2 months. The 5-year outcomes including overall survival, disease-free survival, cause-specific survival, local failure, secondary enucleation rate, and visual acuity (VA) <20/200 were estimated using the Kaplan-Meier method. Overall, there were 7 local failures, 4 distant failures, and 10 secondary enucleations (6 due to local failure and 4 due to treatment complications). Univariate analysis was performed to identify significant prognostic factors associated with disease-free survival (baseline VA in tumor eye, tumor shape), cause-specific survival (diabetic retinopathy), local failure (none found), secondary enucleation rate (diabetic retinopathy, basal tumor dimension) and VA <20/200 (diabetic retinopathy, tumor shape, age, retinal detachment, treatment depth, and history of vision-limiting condition). Conclusions: Our survival and local control outcomes are comparable to those of the COMS. However, VA at 5 years seems to be better. Lower doses of radiation could potentially lead to better visual outcomes.

    Vemurafenib and dabrafenib are both orally bioavailable small molecule agents that block mitogen activated protein kinase signalling in patients with melanoma and BRAF(V600E) mutation. Generalized hypersensitivity reactions to vemurafenib or dabrafenib have not been described. Continuing vemurafenib or dabrafenib therapy despite hypersensitivity reaction is especially important in patients with melanoma and BRAF(V600E) mutation, in whom this mutation plays a critical role in tumour growth. Desensitization protocols to overcome hypersensitivity reactions by gradual reintroduction of small amounts of the offending drug up to full therapeutic doses are available for many anti-cancer agents, including vemurafenib but, to the best of our knowledge, have not been reported for dabrafenib. We describe a patient with metastatic melanoma who developed Type I hypersensitivity reaction to vemurafenib and to subsequent treatment with dabrafenib, and who was successfully treated by drug desensitization which allowed safe prolonged continuation of dabrafenib. The development of hypersensitivity reactions for both dabrafenib and vemurafinib in the current case could be because these drugs have a similar chemical structure and cause a cross-reactivity. However, hypersensitivity reaction to a non-medicinal ingredient shared by the two drugs is also possible. Oral desensitization appears to be an option for patients with hypersensitivity Type I to dabrafenib. This approach may permit clinicians to safely administer dabrafenib to patients who experience hypersensitivity reactions to this life-prolonging medication. © The Author 2015.

  14. Melanoma cells treated with GGTI and IFN-gamma allow murine vaccination and enhance cytotoxic response against human melanoma cells.

    Directory of Open Access Journals (Sweden)

    Guillaume Sarrabayrouse

    Full Text Available BACKGROUND: Suboptimal activation of T lymphocytes by melanoma cells is often due to the defective expression of class I major histocompatibility antigens (MHC-I and costimulatory molecules. We have previously shown that geranylgeranyl transferase inhibition (done with GGTI-298 stimulates anti-melanoma immune response through MHC-I and costimulatory molecule expression in the B16F10 murine model [1]. METHODOLOGY/PRINCIPAL FINDINGS: In this study, it is shown that vaccination with mIFN-gand GGTI-298 pretreated B16F10 cells induces a protection against untreated tumor growth and pulmonary metastases implantation. Furthermore, using a human melanoma model (LB1319-MEL, we demonstrated that in vitro treatment with hIFN-gamma and GGTI-298 led to the up regulation of MHC-I and a costimulatory molecule CD86 and down regulation of an inhibitory molecule PD-1L. Co-culture experiments with peripheral blood mononuclear cells (PBMC revealed that modifications induced by hIFN-gamma and GGTI-298 on the selected melanoma cells, enables the stimulation of lymphocytes from HLA compatible healthy donors. Indeed, as compared with untreated melanoma cells, pretreatment with hIFN-gamma and GGTI-298 together rendered the melanoma cells more efficient at inducing the: i activation of CD8 T lymphocytes (CD8+/CD69+; ii proliferation of tumor-specific CD8 T cells (MelanA-MART1/TCR+; iii secretion of hIFN-gamma; and iv anti-melanoma specific cytotoxic cells. CONCLUSIONS/SIGNIFICANCE: These data indicate that pharmacological treatment of melanoma cell lines with IFN-gamma and GGTI-298 stimulates their immunogenicity and could be a novel approach to produce tumor cells suitable for vaccination and for stimulation of anti-melanoma effector cells.

    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.

Eighteen cases were identified that identified survival of ≥3 years’ duration from metastatic disease (12 American Joint Committee on Cancer [AJCC] Stage IV cases; six AJCC III cases) diagnosis. These were assessed and reported to detail the clinical course. Standard clinical prognostication methods predicted high risk of early mortality in those patients. No identifiable differences could be detected between these and other patients with similar patterns of disease. At evaluation, 17 patients (94%) had survived ≥5 years, and eleven patients (61%) had survived ≥10 years (range: 3–15 years). The median survival duration with metastatic disease was 11 years; 15 remained alive and three had died. Published studies of melanoma therapies were tabled for comparison. The fact that 18 cases of exceptional survival in advanced melanoma were identified is remarkable in itself

    1981-01-01

    Survival of 387 patients treated for cutaneous malignant melanoma at University of Iowa Hospitals during the period 1950--1974 was analyzed. For the entire period, the observed five-year survivals were 57% for women and 33% for men; the corresponding ten-year survivals were 43 and 23%. For both men and women, there was an impressive improvement in outcome between the earliest and the latest periods, so that for 1970--1974, the five-year observed survival was 68% for women and 49% for men. Data are presented on mean age at diagnosis, distribution by stage, site, and sex, and survival by site and sex. The question is raised whether the biologic nature of malignant melanoma is variable, so that increased incidence is associated with better prognosis.

    Full Text Available Anti-programmed cell death-1 (anti-PD-1 antibody shows high therapeutic efficacy in patients with advanced melanoma. However, assessment of its therapeutic activity can be challenging because of tumour enlargement associated with intratumoural inflammation. Because circulating tumour DNA (ctDNA correlates with tumour burden, we assessed the value of ctDNA levels as an indicator of tumour changes. Quantification of ctDNA (BRAFmutant or NRASmutant levels by droplet digital PCR in 5 patients with BRAF or NRAS mutant melanoma during the treatment course showed dynamic changes corresponding to radiological and clinical alterations. In 3 cases in which the anti-PD-1 antibody was effective, ctDNA levels decreased within 2–4 weeks after treatment initiation. In 2 cases in which the anti-PD-1 antibody was ineffective, ctDNA levels did not decrease after treatment initiation. ctDNA could be a useful biomarker to predict early response to treatment in patients with advanced melanoma treated with anti-PD-1 immunotherapy.

    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.

    Peptides derived from tumor associated antigens can be utilized to elicit a therapeutically effective immune response against melanoma in experimental models. However, patient vaccination with peptides - although it is often followed by the induction of melanoma- specific T lymphocytes - is rarely associated with tumor response of clinical relevance. In this review I summarize the principles of peptide design as well as the results so far obtained in the clinical setting while treating cutaneous melanoma by means of this active immunotherapy strategy. I also discuss some immunological and methodological issues that might be helpful for the successful development of peptide-based vaccines.

    Purpose: To evaluate the outcome and patterns of failure for patients with nodal metastases from melanoma treated with combined-modality therapy. Methods and Materials: Between 1983 and 2003, 466 patients with nodal metastases from melanoma were managed with lymphadenectomy and radiation, with or without systemic therapy. Surgery was a therapeutic procedure for clinically apparent nodal disease in 434 patients (regionally advanced nodal disease). Adjuvant radiation was generally delivered with a hypofractionated regimen. Adjuvant systemic therapy was delivered to 154 patients. Results: With a median follow-up of 4.2 years, 252 patients relapsed and 203 patients died of progressive disease. The actuarial 5-year disease-specific, disease-free, and distant metastasis-free survival rates were 49%, 42%, and 44%, respectively. By multivariate analysis, increasing number of involved lymph nodes and primary ulceration were associated with an inferior 5-year actuarial disease-specific and distant metastasis-free survival. Also, the number of involved lymph nodes was associated with the development of brain metastases, whereas thickness was associated with lung metastases, and primary ulceration was associated with liver metastases. The actuarial 5-year regional (in-basin) control rate for all patients was 89%, and on multivariate analysis there were no patient or disease characteristics associated with inferior regional control. The risk of lymphedema was highest for those patients with groin lymph node metastases. Conclusions: Although regional nodal disease can be satisfactorily controlled with lymphadenectomy and radiation, the risk of distant metastases and melanoma death remains high. A management approach to these patients that accounts for the competing risks of distant metastases, regional failure, and long-term toxicity is needed

    A Phase II study to screen for anti-melanoma activity of the heat shock protein 90 (HSP90) inhibitor, 17-AAG (17-allylamino-17-demethoxygeldanamycin) was performed. The primary endpoint was the rate of disease stabilisation in patients with progressive, metastatic melanoma treated with 17-AAG. Secondary endpoints were to determine: the toxicity of 17-AAG, the duration of response(s), median survival and further study the pharmacokinetics and pharmacodynamics of 17-AAG. Patients with metastatic melanoma (progressive disease documented ≤6 months of entering study) were treated with weekly, intravenous 17-AAG. A Simon one sample two stage minimax design was used. A stable disease rate of ≥25% at 6 months was considered compatible with 17-AAG having activity. Fourteen patients (8 male: 6 female) were entered, eleven received 17-AAG (performance status 0 or 1). Median age was 60 (range 29-81) years. The majority (93%) received prior chemotherapy and had stage M1c disease (71%). Toxicity was rarely ≥ Grade 2 in severity and commonly included fatigue, headache and gastrointestinal disturbances. One of eleven patients treated with 17-AAG had stable disease for 6 months and median survival for all patients was 173 days. The study was closed prematurely prior to completion of the first stage of recruitment and limited planned pharmacokinetic and pharmacodynamic analyses. Some evidence of 17-AAG activity was observed although early study termination meant study endpoints were not reached. Stable disease rates can be incorporated into trials screening for anti-melanoma activity and further study of HSP90 inhibitors in melanoma should be considered.

    Abstract 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.

    Surgical removal of regional lymph nodes draining the site of a melanoma is a generally practiced procedure. It is often difficult in many cases of truncal melanomas near the midline or near the waistline to determine which group or groups of nodes to remove. Colloidal Au-198, Tc-99m sulfur colloid, and Tc-99m antimony sulfur colloid have all been used and have given useful clinical information. Objections, however, have been raised to the local radiation dose with these compounds. To reduce this problem while obtaining greater information on lymph flow, the authors have studied dextran, a macromolecule commonly used as plasma substitute. Dextran (average mol. wt. 72,000) labeled with Tc-99m has been used to study lymph drainage from the site of truncal melanoma in 29 patients. Serial images in the first hour following intradermal injection clearly demonstrate tracer in efferent lymphatics within 5 to 10 minutes, and brief pooling in the regional lymph nodes between 20 and 60 minutes. When compared with particulate tracers such as micro Tc-99m sulfur colloid, the Tc-99m dextran appears to move much faster through the lymphatics. Overall distribution of the Tc-99m dextran to lymph nodes is very similar to previous findings with micro Tc-99m sulfur colloid. Dextran drainage to more than one group of regional nodes was seen in 12/29 patients as compared with 17/50 patients using micro Tc-99m sulfur colloid. The superior images with Tc-99m dextran appear to make it the agent of choice

    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.

    Polyacetylenic alcohols derived from Panax ginseng have been studied to be an anticancer reagent previously. One of the Panax ginseng polyacetylenic alcohols, i.e., panaxydol, has been studied to possess an antiproliferative effect on human melanoma cell line (SK-MEL-1). In ths study, radioactive cDNA microarrays enabled an efficient approach to analyze the pattern of gene expression (3.194 genes in a total) simultaneously. The bioinformatics selection of human cDNAs, which is specifically designed for immunology, apoptosis and signal transduction, were arrayed on nylon membranes. Using with {sup 33}P labeled probes, this method provided highly sensitive gene expression profiles of our interest including apoptosis, cell proliferation, cell cycle, and signal transduction. Gene expression profiles were also classified into several categories in accordance with the duration of panaxydol treatment. Consequently, the gene profiles of our interest were significantly up (199 genes, > 2.0 of Z-ratio) or down-(196 genes, < 2.0 of Z-ratio) regulated in panaxydol-treated human melanoma cells.

    The relationship between melanoma and chronic lymphocytic leukemia (CLL) or non-Hodgkin lymphoma (NHL) has been minimally investigated. The objective of this study was to examine the incidence of melanoma in patients with a history of CLL or NHL, and their associated mortality. Cohorts of Kaiser Permanente Southern California members with a history of CLL and NHL were identified. Age-adjusted incidence density rates of melanoma among patients with CLL or NHL were compared with rates of melanoma among the general population of Kaiser Permanente Southern California patients. The mortality of patients with melanoma was examined using Cox proportional hazards modeling. The age-adjusted incidence rate per 100,000 person-years for melanoma among patients with either CLL or NHL was 107 (95% confidence interval 84.4-129.6) versus 25.9 among the general population (95% confidence interval 84.4-129.6, P < .001). Patients with melanoma and a history of CLL or NHL had 2.46 greater odds of death compared with those without CLL or NHL (95% confidence interval 1.77-3.41). This study was retrospective in nature; the International Classification of Diseases, Ninth Revision codes used may contain diagnostic errors; and only overall survival was used in our analysis. Patients with a history of CLL or NHL have a higher incidence of melanoma. Patients with CLL or NHL who are subsequently given the diagnosis of melanoma have a higher mortality than patients with melanoma without a preceding diagnosis of CLL.

  11. Pediatric Melanoma and Drug Development

    Full Text Available Importance—Pediatric melanoma occurs, albeit rarely. Should patients be treated by today’s medical standards, or be subjected to medically unnecessary clinical studies? Observations—We identified international, industry-sponsored pediatric melanoma studies triggered by regulatory demands in www.clinicaltrials.gov and further pediatric melanoma studies demanded by European Union pediatric investigation plans. We retrieved related regulatory documents from the internet. We analyzed these studies for rationale and medical beneficence on the basis of physiology, pediatric clinical pharmacology and rationale. Regulatory authorities define children by chronological age, not physiologically. Newborns’ organs are immature but they develop and mature rapidly. Separate proof of efficacy in underage patients is justified formally/regulatorily but lacks medical sense. Children—especially post-puberty—and adults vis-a-vis medications are physiologically very similar. Two adolescent melanoma studies were terminated in 2016 because of waning recruitment, while five studies in pediatric melanoma and other solid tumors, triggered by European Union pediatric investigation plans, continue recruiting worldwide. Conclusions and Relevance—Regulatory-demanded pediatric melanoma studies are medically superfluous. Melanoma patients of all ages should be treated with effective combination treatment. Babies need special attention. Children need dose-finding and pharmacokinetic studies but adolescents metabolize and respond to drugs similarly to adults. Institutional Review Boards/ethics committees should suspend ongoing questionable pediatric melanoma studies and reject newly submitted questionable studies.

  12. Interpretation of Melanoma Risk Feedback in First-Degree Relatives of Melanoma Patients

    Little is known about how individuals might interpret brief genetic risk feedback. We examined interpretation and behavioral intentions (sun protection, skin screening) in melanoma first-degree relatives (FDRs) after exposure to brief prototypic melanoma risk feedback. Using a 3 by 2 experimental pre-post design where feedback type (high-risk mutation, gene environment, and nongenetic) and risk level (positive versus negative findings) were systematically varied, 139 melanoma FDRs were randomized to receive one of the six scenarios. All scenarios included an explicit reminder that melanoma family history increased their risk regardless of their feedback. The findings indicate main effects by risk level but not feedback type; positive findings led to heightened anticipated melanoma risk perceptions and anticipated behavioral intentions. Yet those who received negative findings often discounted their family melanoma history. As such, 25%, 30%, and 32% of those who received negative mutation, gene-environment, and nongenetic feedback, respectively, reported that their risk was similar to the general population. Given the frequency with which those who pursue genetic testing may receive negative feedback, attention is needed to identify ideal strategies to present negative genetic findings in contexts such as direct to consumer channels where extensive genetic counseling is not required.

    Talimogene laherparepvec (T-VEC) is a herpes simplex virus type 1-derived oncolytic immunotherapy designed to selectively replicate within tumors and produce granulocyte macrophage colony-stimulating factor (GM-CSF) to enhance systemic antitumor immune responses. T-VEC was compared with GM-CSF in patients with unresected stage IIIB to IV melanoma in a randomized open-label phase III trial. Patients with injectable melanoma that was not surgically resectable were randomly assigned at a two-to-one ratio to intralesional T-VEC or subcutaneous GM-CSF. The primary end point was durable response rate (DRR; objective response lasting continuously ≥ 6 months) per independent assessment. Key secondary end points included overall survival (OS) and overall response rate. Among 436 patients randomly assigned, DRR was significantly higher with T-VEC (16.3%; 95% CI, 12.1% to 20.5%) than GM-CSF (2.1%; 95% CI, 0% to 4.5%]; odds ratio, 8.9; P < .001). Overall response rate was also higher in the T-VEC arm (26.4%; 95% CI, 21.4% to 31.5% v 5.7%; 95% CI, 1.9% to 9.5%). Median OS was 23.3 months (95% CI, 19.5 to 29.6 months) with T-VEC and 18.9 months (95% CI, 16.0 to 23.7 months) with GM-CSF (hazard ratio, 0.79; 95% CI, 0.62 to 1.00; P = .051). T-VEC efficacy was most pronounced in patients with stage IIIB, IIIC, or IVM1a disease and in patients with treatment-naive disease. The most common adverse events (AEs) with T-VEC were fatigue, chills, and pyrexia. The only grade 3 or 4 AE occurring in ≥ 2% of T-VEC-treated patients was cellulitis (2.1%). No fatal treatment-related AEs occurred. T-VEC is the first oncolytic immunotherapy to demonstrate therapeutic benefit against melanoma in a phase III clinical trial. T-VEC was well tolerated and resulted in a higher DRR (P < .001) and longer median OS (P = .051), particularly in untreated patients or those with stage IIIB, IIIC, or IVM1a disease. T-VEC represents a novel potential therapy for patients with metastatic melanoma. © 2015 by

  14. Fulminant Diabetes in a Patient with Advanced Melanoma on Nivolumab

    Full Text Available Background. Anti-PD-1 agents were approved for advanced melanoma after the landmark trial Checkmate-037. Anti-PD-1 agents can breach immunologic tolerance. Fulminant diabetes is an immune endocrinopathy that results from a violent immune attack leading to complete destruction of pancreatic beta cells in genetically predisposed people. We present a rare case of fulminant diabetes precipitated by anti-PD-1 immunotherapy. Case. A 61-year-old male with advanced melanoma presented with a three-day history of nausea, vomiting, and malaise. He was started on nivolumab and ipilimumab. After the third dose, he developed a generalized rash and was prescribed high-dose prednisone. Labs revealed potassium 9.5 mmol/L, sodium 127 mmol/L, bicarbonate 31 mmol, arterial blood pH 7.14, and beta-hydroxybutyrate 13.7 mmol/L. He was diagnosed with diabetic ketoacidosis. Hemoglobin A1C was 6.9%. C-peptide was undetectable (<0.1 ng/ml. Glutamic acid decarboxylase autoantibodies, zinc transporter 8 autoantibodies, insulin autoantibodies, islet antigen 2 autoantibodies, and islet cell antibodies were all negative. Conclusion. Anti-PD-1 immunotherapy is effective in cancers refractory to standard chemotherapy. These agents can precipitate autoimmune disorders. As the use of anti-PD-1 agents is expected to rise, physicians should be educated about the potential side effects. We recommend conducting routine blood glucose checks in patients on these agents.

    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.

    Full Text Available Primary malignant melanomas of uterine cervix are quite rarely seen neoplasms, and long-life prognosis of patients with this disease is poor. Immunohistochemical methods and exclusion of other primary melanoma sites are used to confirm the diagnosis. As with other melanomas, cervix malignant melanomas may also cause cardiac metastases. Cardiac metastases are among rarely seen but more commonly encountered cases, compared to primary cardiac tumors. Here, we present a case of biatrial cardiac metastases in a 73-year-old patient with uterine cervix malignant melanomas. The patient underwent echocardiography, cardiac magnetic resonance imaging, and computed tomography. Our report shows the importance of advanced diagnostic techniques, such as cardiac magnetic resonance, not only for the detection of cardiac masses, but for a better anatomic definition and tissue characterization. Although the cases of malignant melanomas leading to multiple cardiac metastasis were reported in literature, the metastatic concurrence of malignant melanomas in both right and left atriums is quite rarely encountered as metastatic malignant melanomas. Also, another intriguing point in our case is that the primary lesion of our case was stemmed from uterine cervix, but not skin.

    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.

    We previously found that administration of an interleukin 2/diphtheria toxin conjugate (DAB/IL2; Denileukin Diftitox; ONTAK) to stage IV melanoma patients depleted CD4 + CD25 HI Foxp3 + regulatory T cells and expanded melanoma-specific CD8 + T cells. The goal of this study was to assess the clinical efficacy of DAB/IL2 in an expanded cohort of stage IV melanoma patients. In a single-center, phase II trial, DAB/IL2 (12 μg/kg; 4 daily doses; 21 day cycles) was administered to 60 unresectable stage IV melanoma patients and response rates were assessed using a combination of 2-[ 18 F]-fluoro-2-deoxy-glucose (FDG)-positron emission tomography (PET) and computed tomography (CT) imaging. After DAB/IL2 administration, 16.7% of the 60 patients had partial responses, 5% stable disease and 15% mixed responses. Importantly, 45.5% of the chemo/immuno-naïve sub-population (11/60 patients) experienced partial responses. One year survival was markedly higher in partial responders (80 ± 11.9%) relative to patients with progressive disease (23.7 ± 6.5%; p value < 0.001) and 40 ± 6.2% of the total DAB/IL2-treated population were alive at 1 year. These data support the development of multi-center, randomized trials of DAB/IL2 as a monotherapy and in combination with other immunotherapeutic agents for the treatment of stage IV melanoma. http://www.clinicaltrials.gov/ct2/show/NCT00299689

    Full Text Available Abstract Background We present our experience of therapeutic vaccination using dendritic cells (DC pulsed with autologous tumor antigens in patients with advanced melanoma. Methods Twenty-one pretreated advanced melanoma patients were vaccinated with autologous DC pulsed with 100 μg/ml of autologous-tumor-lysate (ATL or – homogenate (ATH and 50 μg/ml of keyhole limpet hemocyanin (KLH. The first 8 patients were treated subcutaneously or intradermally with immature-DC (iDC (range 4.5 – 82 × 106 and the remaining 13 intradermally with in vitro matured DC (mDC (range 1.2–26 × 106. Subcutaneous interleukin-2 (3 × 106 IU was administered from days 3 to 7 of each treatment cycle. Results Three of the 8 iDC patients obtained stabilizations (SD, each of 6 months' duration. The 13 mDC patients showed 1 complete response (8 months, 1 partial response (3 months, 2 mixed responses (6 and 12 months and 3 SD (9, 7+, and 3+ months. Overall responses (OR were observed in 4/21 (19% patients, or 4/13 (30.7% considering mDC treatment only. 10/21 (47.6% patients showed non progressive disease (NPD, with 7/13 (53.8% cases of NPD for mDC-treated patients. No major toxicities were observed. The positive delayed-type hypersensitivity (DTH test to ATL/ATH and/or KLH correlated with increased overall survival (OS. Median OS was 24 months (range 3 – 45 for the 10 DTH-positive (1 iDC and 9 mDC and 5 months (range 3–14 for the 11 DTH-negative patients (P in vitro evaluation of gamma IFN-secreting T-cells in 10 patients showed good correlation with both DTH (75% and clinical outcome (70%. Conclusion Vaccination using DC pulsed with ATL/ATH and KLH in advanced melanoma patients is well tolerated and can induce a clinical response, especially when mDC are used. Successful immunization, verified by positive DTH, leads to longer survival.

Overall responses (OR) were observed in 4/21 (19%) patients, or 4/13 (30.7%) considering mDC treatment only. 10/21 (47.6%) patients showed non progressive disease (NPD), with 7/13 (53.8%) cases of NPD for mDC-treated patients. No major toxicities were observed. The positive delayed-type hypersensitivity (DTH) test to ATL/ATH and/or KLH correlated with increased overall survival (OS). Median OS was 24 months (range 3-45) for the 10 DTH-positive (1 iDC and 9 mDC) and 5 months (range 3-14) for the 11 DTH-negative patients (P < 0.001). The in vitro evaluation of gamma IFN-secreting T-cells in 10 patients showed good correlation with both DTH (75%) and clinical outcome (70%). Vaccination using DC pulsed with ATL/ATH and KLH in advanced melanoma patients is well tolerated and can induce a clinical response, especially when mDC are used. Successful immunization, verified by positive DTH, leads to longer survival.

    In patients with melanoma, early dissemination via lymphatic and hematogenous routes is frequently seen. Thus, besides clinical follow-up examination and imaging, reliable melanoma-specific serological tumor markers are needed. We retrospectively compared two serum markers for melanoma, S100 and melanoma-inhibitory activity (MIA), for monitoring of patients with metastatic melanoma under either adjuvant or therapeutic vaccination immunotherapy with dendritic cells (DC). Serum was obtained from a total of 100 patients (28 patients in stage III and 72 patients in stage IV, according to the American Joint Committee on Cancer 2002) at regular intervals during therapy, accompanied by follow-up imaging. When relapse was detected, both markers often remained within normal range. In contrast, in patients with metastatic measurable disease receiving therapeutic and not adjuvant DC vaccination, an increase of both markers was a strong indicator for disease progression. When comparing both markers in the whole study population, MIA showed a superior sensitivity to detect disease progression. S100 and MIA are highly sensitive tumor markers for monitoring of patients with melanoma with current metastases, but less sensitive for monitoring of tumor-free patients. In the current study, MIA had a slightly superior sensitivity to detect progressive disease compared to S100 and seems to be more useful in monitoring of patients with metastatic melanoma receiving immunotherapy.

    Alternative approaches to improve the treatment of advanced melanomas are highly needed. The disintegrin domain of metalloproteinases binds integrin receptors on tumor cells, blocking migration, invasion, and metastatization. Previous studies showed that jararhagin, from the Bothrops jararaca snake venom, induces changes in the morphology and viability of SK-Mel-28 human melanoma cells, and decreases the number of metastases in mice injected with pre-treated cells. The purpose of this study was to evaluate the molecular effects of jararhagin on SK-Mel-28 cells and fibroblasts, concerning the expression of integrins, cadherins, caspases, and TP53 genes. Sub-toxic doses of jararhagin were administered to confluent cells. RT-PCR was performed following extraction of total RNA. Jararhagin treatments induced similar morphological alterations in both normal and tumor cells, with higher IC50 values for fibroblasts. Integrin genes were downregulated in untreated cells, except for ITGA6a,b, ITGAv, and ITGB3 which were highly expressed in SK-Mel-28. The integrin expression profiles were not affected by the toxin. However, jararhagin 30ng/μl upregulated genes TP53, CDKN1A, CDKN2A, CASP3, CASP5, CASP6, CASP8, and E-CDH in SK-Mel-28, and genes ITGB6, ITGB7, CASP3, TP53, and CDKN1B in fibroblasts. Appropriate jararhagin concentration can have apoptotic and suppressant effects on SK-Mel-28 cells, rather than on fibroblasts, and can be used to develop potential anti-cancer drugs.

    Full Text Available Abstract Background Cutaneous Malignant Melanoma causes over 75% of skin cancer-related deaths, and it is clear that many factors may contribute to the outcome. Matrix Metalloproteinases (MMPs play an important role in the degradation and remodeling of the extracellular matrix and basement membrane that, in turn, modulate cell division, migration and angiogenesis. Some polymorphisms are known to influence gene expression, protein activity, stability, and interactions, and they were shown to be associated with certain tumor phenotypes and cancer risk. Methods We tested seven polymorphisms within the MMP-9 gene in 1002 patients with melanoma in order to evaluate germline genetic variants and their association with progression and known risk factors of melanoma. The polymorphisms were selected based on previously published reports and their known or potential functional relevance using in-silico methods. Germline DNA was then genotyped using pyrosequencing, melting temperature profiles, heteroduplex analysis, and fragment size analysis. Results We found that reference alleles were present in higher frequency in patients who tend to sunburn, have family history of melanoma, higher melanoma stage, intransit metastasis and desmoplastic melanomas among others. However, after adjustment for age, sex, phenotypic index, moles, and freckles only Q279R, P574R and R668Q had significant associations with intransit metastasis, propensity to tan/sunburn and primary melanoma site. Conclusion This study does not provide strong evidence for further investigation into the role of the MMP-9 SNPs in melanoma progression.

    Our study was conducted to explore the efficacy of autologous cytokine-induced killer (CIK) cells in patients with advanced malignant melanoma. Materials & Methods: Here we reviewed 113 stage IV malignant melanoma patients among which 68 patients received CIK cell immunotherapy alone, while 45 patients accepted CIK cell therapy combined with chemotherapy. Results: We found that the median survival time in CIK cell group was longer than the combined therapy group (21 vs 15 months, p = 0.07). In addition, serum hemoglobin level as well as monocyte proportion and lymphocyte count were associated with patients' survival time. These indicated that CIK cell immunotherapy might extend survival time in advanced malignant melanoma patients. Furthermore, serum hemoglobin level, monocyte proportion and lymphocyte count could be prognostic indicators for melanoma.

    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

    2013-01-01

    Purpose 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 and Methods 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). Results 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. Conclusion 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.

    2011-01-01

    Due to intensified research in recent years, the understanding of the molecular mechanisms involved in the development of melanoma has dramatically improved. The discovery of specific, causal mutations such as BRAF or KIT oncogenes not only renders a targeted and thus more effective therapeutic approach possible, but also gives rise to a new genetic-based classification. Targeting just a few out of several potential mutations, BRAF-Inhibitors such as PLX 4032 achieved already tremendous results in the therapy of metastatic melanoma. Up to now, the correlation of clinical, histomorphologic, and genetic features is, however, not understood. Even more, is it not well known precisely what kind of molecular changes predispose the primary melanoma for metastasis. The identification of morphological surrogates and prognostic parameters in tumors with such genetic alteration seems therefore crucial when differentiating and classifying this heterogeneous tumor entity in more detail and thus facilitates the stratification of prognosis as well as therapy. This review summarizes the current understanding of carcinogenesis and gives a detailed overview of known morphologic and potentially future genetic prognostic parameters in malignant melanoma.

    The results are reported of five-year and ten-year survival of malignant melanoma patients treated postoperatively by actinotherapy. In patients where lymph flow was not apparent, 2.5 Gy of daily doses of electron irradiation from a 6-8 MeV betatron were used centred on the scar. The total dose was 60 Gy. Where the lymph flow could be identified, cobalt or cesium sources were used to deliver a total dose of 50 Gy in 2.5 Gy daily. Both five-year and ten-year survival was significantly better than in patients treated with surgery only, without irradiation. 55% of the patients on combined management survived for more than 5 years, 86% of them without relapses. 41% patients survived for 10 years, of which 92% without relapse. In contrast, the corresponding figures for the patients treated with surgery only were 42% and 71% respectively for the five-year survival, and 26% and 70% respectively for the ten-year survival.

  14. Phenotypic and functional characteristics of blood natural killer cells from melanoma patients at different clinical stages.

    Full Text Available Melanomas are aggressive skin tumors characterized by high metastatic potential. Immunotherapy is a valuable alternative for metastatic melanoma patients resistant to chemotherapy. Natural Killer (NK cells are efficient anti-tumor cytotoxic effectors. We previously showed that blood NK cells from stage IV metastatic melanoma patients display decreased NK receptors and that chemotherapy modifies the functional status of blood NK cells. To investigate the role of NK cells along melanoma progression, we have here studied NK cells from patients at different stages of the disease. First, we showed that ex vivo NK cells from certain stage III-IV patients displayed low degranulation potential. Using a dynamic label-free assay, we found that immunoselected IL-2 activated blood NK cells from patients efficiently lysed melanoma cells through NKp46 and NKG2D receptors, independently to the clinical stage. Moreover, the ex vivo phenotype of circulating NK cells from 33 patients (stage I to IV was extensively analyzed. NK cells from patients displayed higher variability in the percentages of Natural Cytotoxicity Receptors (NCR and Natural Killer Group 2D (NKG2D receptor expression compared to donor NK cells. The main defect was the decreased expression of NCR1 (NKp46 by NK cells from metastatic patients. Interestingly, we found a positive correlation between the NK cell percentages of NKp46 and the duration of stage IV in melanoma patients. Finally, we showed that NK cells infiltrated primary melanomas and displayed a predominant peritumoral distribution. These results are new arguments for the development of NK-based therapies in melanoma patients.

    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...

    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

    Full Text Available A 65-year-old woman diagnosed with a nodular melanoma on the right shoulder had a PET/CT scan 13 months later demonstrating a FDG-avid mass in the left masseter muscle, which was asymptomatic and not clinically evident. Pathologic analysis confirmed metastasis of melanoma. Further subcutaneous, intramuscular and bone metastases developed and the patient was treated with surgery and immunotherapy. The patient is in complete-remission with no evident metastases seen on PET/CT 2.5 years after treatment with adoptive cell therapy using tumor-infiltrating lymphocytes (TIL therapy. Asymptomatic skeletal muscle metastases identified with PET/CT can have therapeutic and prognostic implications and a PET/CT scan should be performed as a true whole-body scan.

    Inhibitors of mutant BRAF are emerging as standard of care in patients with metastatic melanoma who carry relevant oncogenic mutations. However, BRAF inhibitors are found to induce cutaneous squamous cell carcinoma (cuSCC). Population-based background rates of cuSCC and non-cutaneous squamous cell carcinoma (non-cuSCC) in the metastatic melanoma population may contextualize safety signals from randomized clinical trials or the clinics. However, these background rates are lacking. We conducted a historical cohort study to evaluate the background rates of new-onset non-melanoma skin lesions and non-cuSCC among 2,814 metastatic malignant melanoma patients diagnosed in 1997-2010, identified through the Danish Cancer Registry and the National Pathology Registry. Patients were excluded if they had a history of cancer before the metastatic melanoma diagnosis, other than skin cancers. We determined the incidence of non-melanoma malignant skin lesions and non-cuSCC that occurred post metastatic melanoma diagnosis, censoring patients at death, emigration, or December 31, 2011 (end of study period), whichever came first. The median age at metastatic melanoma diagnosis was 64 years. Over 40% of patients died within one year of metastatic diagnosis and ~70% died within 5 years. The percentages of patients with prior history or prevalent disease at metastatic melanoma diagnosis included: 8.6% with cuSCC or basal cell carcinoma (BCC), 3.9% with actinic keratosis (AK), and 0.7% with Bowen's disease. No patients had past or current non-cuSCC per study exclusion criterion. The incidence of non-melanoma skin lesions during the 6 months post-metastatic melanoma diagnosis was as follows: BCC, 1.8% (42.5 per 1000 person-years [PY]); AK, 0.8% (18.6 per 1000 PY); cuSCC, 0.1% (1.7 per 1000 PY); Bowen's disease, 0.04% (0.8 per 1000 PY); and keratoacanthoma (KA), 0%.

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

    Full Text Available This study examined whether patient-identified melanomas were more advanced than dermatologist-identified tumors at routine clinic visits, and whether a personal or family history of skin cancer was associated with patterns of detection. A retrospective chart review was performed on melanoma patients (N=201 in a private dermatology clinic. Variables included age, gender, pattern of detection (i.e., patient or a board certified dermatologist, personal or family history of skin cancer, skin type, and previous sun exposure, as well as tumor location and severity. Dermatologist-diagnosed melanomas were less invasive (P<0.0005, and more likely present on the chest, back, and legs (P<0.01. Conversely, patient-identified lesions were more likely to occur on the face, neck and scalp, be associated with younger patients, and a family history of melanoma, but not other types of skin cancer (P<0.01. In a post-hoc analysis examining these factors as predictors of tumor invasiveness, only diagnostic source was significant. Specifically, dermatologist-identified tumors were significantly less invasive than patient-identified tumors. Although age, family history, and tumor location played roles in the early detection of melanomas, the most important factor was diagnostic source. Thus, board-certified dermatologists play a key role in the early detection of malignant melanoma.

    A useful and practical guide is developed to better track to the uveal melanoma, due to its highly malignant character. Melanoma of the uveal tract (choroid, iris, ciliary body) has been the intraocular tumor most frequent in adults. The biopsy has been inaccessible, due to its location; therefore, the diagnostic should be based on clinical examination and the correct utilization of the diagnostic procedures (ultrasound, fluorescent angiography, computed axial tomography and magnetic resonance). The cases are diagnosed in the histological examination of the operatory piece post-enucleation for other causes. Epidemiological research has been key to determine the associated factors and better to understand the mechanisms of onset of the disease. Anatomopathological studies of choroidal melanoma have permitted to know the natural history of the disease. The decrease of the visual acuity, pain or inflammation are presented as a defect in the visual field. Different techniques to diagnose the disease are explained. Ultrasound in mode A and B, computed axial tomography and magnetic resonance are the diagnostic method of election. Ultrasound has been the primary method of diagnostic, giving the size and vascularisation, useful in tracking, when they are treated in shape conservatively, showing changes in echogenicity and less vascularisation as good response to treatment. The treatments of choroidal melanoma are specified. The correct interpretation of the clinical symptoms and early utilization of diagnostic imaging methods, have permitted to establish the adequate therapeutic and to avoid local and distant metastasis. The uveal melanoma, depending on their size and location, traditionally has been treated by enucleation. Data from the literature and authors, have promoted the conservation of the ocular globe, depending on the size of the tumor. Transpupillary thermotherapy has been an available alternative for small tumors in Costa Rica and level of social security

    Two HLA-A2-positive patients with advanced stage IV melanoma were treated with monocyte-derived dendritic cells (DC) pulsed with either tumor peptide antigens from gp100, MART-1 and MAGE- 3 alone or in combination with autologous oncolysates. Clinically, the rapid progression of disease...... by Western blotting was decreased in PBL at this time. In summary, our data confirm that DC-based vaccinations induce peptide-specific T cells in the peripheral blood of advanced-stage melanoma patients. Although successful induction of systemic tumor antigen-specific CTL may not lead to objective clinical...

    Metastatic melanoma is a highly aggressive cancer, often striking in the prime of life. This study provides new information directly from advanced melanoma (stage III and IV) patients on how their disease impacts their health-related quality of life (HRQL). Twenty-nine in-depth, qualitative interviews were conducted with adult patients with advanced melanoma in Canada. A semi-structured interview guide was used. Interviews were transcribed verbatim and key concepts were identified using a grounded theory analytic approach. Many patients' journeys began with the startling diagnosis of an invasive disease and a vastly shortened life expectancy. By the time they reached an advanced stage of melanoma, these patients' overall functioning and quality of life had been greatly diminished by this quickly progressing cancer. The impact was described in terms of physical pain and disability, emotional distress, diminished interactions with friends and family, and burden on caregivers. Our findings provide evidence of signs, symptoms, and functional impacts of advanced melanoma. Signs and symptoms reported (physical, mental, and social) confirm and expand on those reported in the existing clinical literature. Primary care physicians should be better trained to identify melanomas early. Oncology care teams can improve on their current approaches for helping patients navigate treatment options, with information about ancillary services to mitigate disease impacts on HRQL, such as mental health and social supports, as well as employment or financial support services.

    Full Text Available Summary: Therapy of advanced melanoma is changing dramatically. Following mutational and biological subclassification of this heterogeneous cancer, several targeted and immune therapies were approved and increased survival significantly. To facilitate further advancements through pre-clinical in vivo modeling, we have established 459 patient-derived xenografts (PDX and live tissue samples from 384 patients representing the full spectrum of clinical, therapeutic, mutational, and biological heterogeneity of melanoma. PDX have been characterized using targeted sequencing and protein arrays and are clinically annotated. This exhaustive live tissue resource includes PDX from 57 samples resistant to targeted therapy, 61 samples from responders and non-responders to immune checkpoint blockade, and 31 samples from brain metastasis. Uveal, mucosal, and acral subtypes are represented as well. We show examples of pre-clinical trials that highlight how the PDX collection can be used to develop and optimize precision therapies, biomarkers of response, and the targeting of rare genetic subgroups. : Krepler et al. have established a collection of melanoma patient-derived xenografts (PDX. Melanoma is a very heterogeneous cancer, and this large collection includes even rare subtypes and genetic aberrations in sufficient numbers. Multiple PDX from therapy-resistant patients are characterized and tested in pre-clinical trials for second line therapies.

    The clinical outcome of six skin melanoma BNCT irradiations is presented. Three patients (A, B and C), with multiple subcutaneous skin metastases progressed to chemotherapy were infused with ∼14 g/m 2 of boronophenylalanine ( 10 BPA)-fructose and irradiated in the hyperthermal neutron beam of the RA-6 reactor. Patient A received two one fraction irradiations in different areas of the leg, B received one fraction and C was irradiated in three consecutive fields at the calf, heel and foot sole. The maximum prescribed dose to normal skin ranged from 16.5 to 24 Gy-Eq. With a minimum follow-up of 10 months there was a G1 acute epithelitis in A and B and a G3 in C. No late toxicity was observed. Due to the in-field tumor-growth-delay and the absence of severe acute and/or late toxicity observed during the follow-up period, a dose-escalation trial is ongoing.

    Full Text Available Abstract Background Ipilimumab induces long-lasting clinical responses in a minority of patients with metastatic melanoma. To better understand the mechanism(s of action and to identify novel biomarkers associated with the clinical benefit and toxicity of ipilimumab, baseline characteristics and changes in CD4+ and CD8+ T cells from melanoma patients receiving ipilimumab were characterized by gene profiling and flow cytometry. Methods Microarray analysis of flow-cytometry purified CD4+ and CD8+ T cells was employed to assess gene profiling changes induced by ipilimumab. Selected molecules were further investigated by flow cytometry on pre, 3-month and 6-month post-treatment specimens. Results Ipilimumab up-regulated Ki67 and ICOS on CD4+ and CD8+ cells at both 3- and 6-month post ipilimumab (p ≤ 0.001, decreased CCR7 and CD25 on CD8+ at 3-month post ipilimumab (p ≤ 0.02, and increased Gata3 in CD4+ and CD8+ cells at 6-month post ipilimumab (p ≤ 0.001. Increased EOMES+CD8+, GranzymeB+EOMES+CD8+ and decreased Ki67+EOMES+CD4+ T cells at 6 months were significantly associated with relapse (all p ≤ 0.03. Decreased Ki67+CD8+ T cells were significantly associated with the development of irAE (p = 0.02. At baseline, low Ki67+EOMES+CD8+ T cells were associated with relapse (p ≤ 0.001, and low Ki67+EOMES+CD4+ T cells were associated with irAE (p ≤ 0.008. Conclusions Up-regulation of proliferation and activation signals in CD4+ and CD8+ T cells were pharmacodynamic markers for ipilimumab. Ki67+EOMES+CD8+ and Ki67+EOMES+CD4+T cells at baseline merit further testing as biomarkers associated with outcome and irAEs, respectively.

    Purpose: Ipilimumab (Ipi), a monoclonal antibody against cytotoxic T-lymphocyte antigen-4, has been shown to improve survival in patients with metastatic melanoma. In this single-institution study, we investigated the safety and efficacy of stereotactic radiosurgery (SRS) for patients with melanoma brain metastases (BMs) who also received Ipi. Methods and Materials: From 2005 to 2011, 46 patients with melanoma received Ipi and underwent single-fraction SRS for BMs. A total of 113 BMs (91% intact, 9% postoperative) were treated with a median dose of 21 Gy (range, 15-24 Gy). Ipi was given at 3 mg/kg (54%) or 10 mg/kg (46%) for a median of 4 doses (range, 1-21). Adverse events were recorded with the use of the Common Terminology Criteria for Adverse Events 3.0. Kaplan-Meier methods were used to estimate survival, and Cox regression was used to investigate associations. Results: Fifteen patients received SRS during Ipi, 19 received SRS before Ipi, and 12 received SRS after Ipi. Overall survival (OS) was significantly associated with the timing of SRS/Ipi (P=.035) and melanoma-specific graded prognostic assessment (P=.013). Patients treated with SRS during or before Ipi had better OS and less regional recurrence than did those treated with SRS after Ipi (1-year OS 65% vs 56% vs 40%, P=.008; 1-year regional recurrence 69% vs 64% vs 92%, P=.003). SRS during Ipi also yielded a trend toward less local recurrence than did SRS before or after Ipi (1-year local recurrence 0% vs 13% vs 11%, P=.21). On magnetic resonance imaging, an increase in BM diameter to >150% was seen in 50% of patients treated during or before Ipi but in only 13% of patients treated after Ipi. Grade 3 to 4 toxicities were seen in 20% of patients. Conclusion: Overall, the combination of Ipi and SRS appears to be well tolerated. Concurrent delivery of Ipi and SRS is associated with favorable locoregional control and possibly longer survival. It may also cause a temporary increase in tumor size, possibly

    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.

    PURPOSE: We wanted to study whether an allogeneic melanoma lysate would be a feasible stimulatory antigen source for detection of a peripheral CD4+ T-cell immune response in patients with medically untreated malignant melanoma. The lysate was produced from a melanoma cell line (FM3.29) which...... was found in 1 of 4 patients radically operated for localized disease, whereas no responders were seen among 7 healthy donors. The fraction of circulating lysate-activated T cells ranged from 0.0037% to 0.080% of the CD4+ population. A negative result of the assay was found occasionally, especially...... expresses high amounts of melanoma antigens. METHODS: Fresh peripheral blood was incubated with and without lysate for 6 h in the presence of anti-CD28/anti-CD49d MoAb (for costimulation).

    Full Text Available 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.

    Patients with familial melanoma or multiple primary melanoma represent a high-risk population to hereditary melanoma. Mutations in susceptibility genes, such as CDKN2A, CDK4 and MC1R, have been associated with the development of melanoma. The purpose of this study was to determine the genotypic background of patients with familial and/or multiple melanoma in southern Brazil. This study analysed 33 cases (5 patients with multiple primary melanoma and 28 patients from families with at least two well documented cases) and 29 controls. Genomic analysis of CDKN2A and CDK4 genes by PCR-SSCP analysis and sequencing and direct sequencing of MC1R were performed in all individuals. No functional mutations in CDKN2A or CDK4 were detected in the 62 individuals. Infrequent variants in polymorphic loci of CDKN2A gene were identified in 15 participants (24.2%) and 24/33 (72.8%) cases and 19/27 (70.4%) controls reported at least one infrequent variant in MC1R (P = 0.372). Furthermore, a non-significant tendency towards an association between melanoma risk and MC1R variants G274A and C451T and a non-significant linear tendency to the number of infrequent high-risk variants in MC1R were observed. These results suggest that in southern Brazilian population, CDKN2A or CDK4 germinal alterations may have a weaker influence than previously thought and environmental risk factors may play a central role in melanoma susceptibility. However, considering the tendency observed for gene MC1R, low-penetrance genes may be a relevant aetiological factor in southern Brazil with fair skin population and high sunlight exposure. © 2012 The Authors.

Recent studies indicate that long non-coding RNAs are involved in the pathogenesis of malignant melanoma. This study aims to investigate the role of the long non-coding RNA H19 in melanoma and to explore the underlying molecular mechanisms. Materials and methods: The expression levels of H19 in clinical samples and melanoma cells were determined by quantitative real-time PCR. The cell growth and cell metastasis were assessed by Cell Counting Kit 8, cell invasion and wound healing assays. Cell apoptosis and cell cycle were determined by flow cytometry. Protein levels were determined by Western blotting assay. Results: H19 was highly expressed in melanoma tissues compared to normal adjacent skin tissues, and the tissue expression level of H19 from melanoma patients with metastasis was significantly higher than that from patients without distant metastasis. In addition, the high expression of H19 in melanoma tissues was associated with advanced tumor invasion and TNM stage, distal metastasis, lymph node metastasis and shorter overall survival in patients with melanoma. The in vitro functional assays showed that knockdown of H19 inhibited cell growth, invasion and migration and also induced cell apoptosis as well as G0/G1 arrest in melanoma cells. Further quantitative real-time PCR and Western blot experiments showed that knockdown of H19 differentially regulated the epithelial–mesenchymal transition (EMT-related gene expressions and reversed EMT in melanoma cell lines. Knockdown of H19 suppressed in vivo tumor growth and modulated the

    Melanoma is the most common oral tumor in dogs, characterized by rapid growth, local invasion, and high metastatic rate. The goal of this study was to evaluate the combination of radiation therapy and DNA tumor vaccine. We hypothesized, that the concurrent use would not increase toxicity. Nine dogs with oral melanoma were treated with 4 fractions of 8 Gray at 7-day intervals. The vaccine was given 4 times every 14 days, beginning at the first radiation fraction. Local acute radiation toxicities were assessed according to the VRTOG toxicity scoring scheme over a time period of 7 weeks. In none of the evaluated dogs, mucositis, dermatitis and conjunctivitis exceeded grade 2. In 3 dogs mild fever, lethargy, and local swelling at the injection site were seen after vaccine application. In conclusion, the concurrent administration of radiation therapy and vaccine was well tolerated in all dogs.

    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 (Pthick 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. © 2015 American Cancer Society.

    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.

    Survival data are mixed comparing patients with multiple primary melanomas (MPM) to those with single primary melanomas (SPM). We compared MPM versus SPM patient survival using a matching method that avoids potential biases associated with other analytic approaches. Records of 14,138 individuals obtained from the Surveillance, Epidemiology, and End Results registry of all melanomas diagnosed or treated in Utah between 1973 and 2011 were reviewed. A single matched control patient was selected randomly from the SPM cohort for each MPM patient, with the restriction that they survived at least as long as the interval between the first and second diagnoses for the matched MPM patient. Survival curves (n = 887 for both MPM and SPM groups) without covariates showed a significant survival disadvantage for MPM patients (chi-squared 39.29, P < .001). However, a multivariate Cox proportional hazards model showed no significant survival difference (hazard ratio 1.07, P = .55). Restricting the multivariate analysis to invasive melanomas also showed no significant survival difference (hazard ratio 0.99, P = .96). Breslow depth, ulceration status, and specific cause of death were not available for all patients. Patients with MPM had similar survival times as patients with SPM.

    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). 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. 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.

    NeuGc-containing gangliosides have been described in melanoma cells and are an attractive target for cancer immunotherapy because they are minimally or not expressed in normal human tissues. Melanoma patients treated with a vaccine based on N-glycolyl gangliosides have shown benefit in progression free survival and overall survival. We conducted a multicenter Phase I/II clinical trial in patients with metastatic cutaneous melanoma treated with the N-gycolyl GM3/very-small-size proteoliposomes vaccine by the subcutaneous route. Selecting the optimal biological dose of the vaccine was the principal objective based on immunogenicity, efficacy, and safety results. Six dose levels were studied and the treatment schedule consisted of five doses administered every 2 weeks and then monthly until 15 doses had been given. Dose levels evaluated were 150, 300, 600, 900, 1200, and 1500 μg with five patients included in each dose level except the 900 μg dose (n = 10). Immunogenicity was determined by antibody titers generated in patients after vaccination. Antitumor effect was measured by response criteria of evaluation in solid tumors and safety was evaluated by common toxicity criteria of adverse events. The vaccine was safe and immunogenic at all doses levels. The most frequent adverse events related to vaccination were mild to moderate injection site reactions and flu-like symptoms. Vaccination induced specific anti-NeuGcGM3 immunoglobulin M and immunoglobulin G antibody responses in all patients. Disease control (objective response or stable disease) was obtained in 38.46% of patients. Global median overall survival was 20.20 months. Two patients achieved overall survival duration of about 4 and 5 years, respectively. The 900 μg dose resulted in overall survival duration of 19.40 months and was selected as the biological optimal dose

    Full Text Available 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 188Re-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 188Re-6D2 were given while unlabeled antibody preload was escalated. In Phase Ib, the dose of 188Re-6D2 was escalated to 54 mCi. SPECT/CT revealed 188Re-6D2 uptake in melanoma metastases. The mean effective half-life of 188Re-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 188Re-6D2 was well tolerated, localized in melanoma metastases, and had antitumor activity, thus warranting its further investigation in patients with metastatic melanoma.

    An estimated 20 - 40% of cancer patients will develop brain metastases that are the most common intracranial tumors in adults. Patients with cerebral metastases represent a variegate group where selection of the most appropriate treatment depends on many patient- and disease-related factors. The impact of therapeutic option on overall survival is lacking and it is important to consider quality of life (QOL) when treating patients with brain metastases. A considerable proportion of patients are treated with palliative approaches such as whole-brain radiotherapy. The role of chemotherapy was limited in the past. Recently, several chemotherapeutic agents have been identified as potentially useful. This article examines the pharmacokinetics, efficacy and safety and tolerability of fotemustine (FTM) for the management of patients with cerebral metastasis from melanoma and non-small cell lung cancer (NSCLC). FTM is a third-generation nitrosourea that has proved its efficacy on brain metastases of melanoma and showed promising results for the treatment of brain metastasis of NSCLC because of its ability to pass the blood-brain barrier.

    The survival curves for melanoma cells exposed to single radiation doses in vitro and the specific growth delays for melanoma xenografts irradiated with single doses in vivo were found to differ considerably among individual cell lines and tumours. In fact, the differences could be almost as large as the largest differences observed among cell lines and xenografts from tumours of different histology with very different clinical radiocurability. Moreover, radiobiologic parameters that may have significant influence on tumour response to fractionated irradiation, e.g. growth rate, hypoxic fraction, reoxygenation ability, PLD-repair capacity and contact repair capacity, were found to differ greatly in magnitude among individual melanomas. This review therefore concludes that malignant melanoma is a tumour type that is very heterogeneous in radioresponsiveness, i.e. malignant melanomas should no longer be considered to be radiation resistant in general. The values of the α/β ratio derived from cell survival curves for melanoma cells irradiated in vitro and melanoma xenografts irradiated in vivo were found to cover a wide range relative to those for acutely and late responding normal tissues. Although these α/β ratios are no more than estimates of the effective α/β ratios in a clinical situation, they still indicated that hyperfractionation may be beneficial in the treatment of some melanomas, whereas others may be more efficiently treated by use of conventional fractionation regimes, either based on 2 Gy or higher doses per fraction. Consequently, optimum radiation therapy of malignant melanoma will probably require an individualized treatment strategy. In vitro assays for prediction of radiocurability and choice of treatment strategy for individual melanoma patients seem therefore highly warranted. (orig.)

    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, pimmunotherapy utilization (all pimmunotherapy 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.

    Purpose. - Iodine 125 curietherapy is one of the conservative treatments of uveal melanoma. The technique used to achieve these results was simplified through the physical characteristics of the radioelement and the optimized-dosimetry program employed. Patients and methods. - 78 patients with choroidal melanoma were treated with iodine 125. About 100 Gy were delivered to the superior pole of the tumour. The minimal length of follow-up was 17 months and the average, 67 months. Results. -There was 88% local control, leading to lowered visual acuity in 76 % of the cases. Radiation retinopathy, directly related to proximity to the macula, is the principle etiology. Seven patients died of hepatic metastasis, five patients were enucleated. Four patients were further treated with proton-therapy to make up for non-control locally. Conclusion. -One dose of 100 Gy to the superior pole of the tumor seemed to lead to good local control, with the exception of complications related to proximity to the macula and the optic nerve. In this attempt to optimize irradiation, the time lapse between any benefit in local control derived from irradiation and post-therapeutic complications observed remains insufficient to evaluate any relationship.

    Full Text Available Purpose: The BRAF V600E mutation has been described in melanomas occurring in the Caucasian, European, and Asian populations. However, in the Mexican population, the status and clinical significance of BRAF mutation has not been researched on a large scale. Methods: Consecutive BRAF-tested Mexican patients with metastatic melanoma (n = 127 were analyzed for mutations in exon 15 of the BRAF gene in genomic DNA by real-time polymerase chain reaction technology for amplification and detection. The results were correlated with the clinical-pathologic features and the prognosis of the patients. Results: The frequency of somatic mutation V600E within the BRAF gene was 54.6% (43 of 127 patients. Nodular melanoma was the most prevalent subtype in our population, with BRAF mutations in 37.2% (16 of 55 patients. In contrast, superficial spread had a frequency of 18.6% BRAF mutation (eight of 24. Other clinicopathologic features were assessed to correlate with the mutation status. Conclusion: This study searched for the most prevalent BRAF V600E mutation type in melanoma in a heterogeneous population from Mexico. Nodular melanoma was found to be the most prevalent in metastatic presentation and the presence of BRAF V600E mutation, perhaps related to the mixed ancestry; in the north, ancestry is predominantly European and in the south, it is predominantly Asian. The outcomes of the mutation correlations were similar to those found in other populations.

    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.

    Understanding the perceptions of patients and oncology nurses about the relative importance of benefits and risks associated with newer treatments of advanced melanoma can help to inform clinical decision-making. The aims of this study were to quantify and compare the views of patients and oncology nurses regarding the importance of attributes of treatments of advanced melanoma. A discrete choice experiment (DCE) was conducted in US-based oncology nurses and patients diagnosed with advanced melanoma. Patients and nurses were enlisted through online panels. In a series of scenarios, respondents had to choose between 2 hypothetical treatments, each with 7 attributes: mode of administration (MoA), dosing schedule (DS), median duration of therapy (DoT), objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and grade 3 or 4 adverse events (AEs). Hierarchical Bayesian logistic regression models were used to estimate preference weights. A total of 200 patients with advanced melanoma and 150 oncology nurses participated. The relative importance estimates of attributes by patients and nurses, respectively, were as follows: OS, 33% and 28%; AEs, 29% and 26%; ORR, 25% and 27%; PFS, 12% and 15%; DS, 2% and 3%; DoT, 0% and 0%; and MoA, 0% and 0%. Both patients and oncology nurses valued OS, ORR, and AEs as the most important treatment attributes for advanced melanoma, followed by PFS, whereas DS, DoT, and MoA were given less value in their treatment decisions. Oncology nurses and patients have similar views on important treatment considerations for advanced melanoma, which can help build trust in shared decision-making.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    vemurafenib are both available to patients treated by the National Health Service (NHS) in England via a Patient Access Scheme (PAS) in which the costs of the drugs are discounted. Using these discounted costs, the incremental cost-effectiveness ratios (ICERs) generated by the company were £60,980 per quality-adjusted life-year (QALY) for dabrafenib versus dacarbazine and £11,046 per QALY gained for dabrafenib versus vemurafenib. The ERG considered the economic model structure developed by the company to derive the ICERs to be overly complex and based on unsubstantiated assumptions, most importantly in relation to the projection of OS. Applying the latest OS data from BREAK-3 to a less complex model structure increased the estimated ICER for dabrafenib compared with dacarbazine from £60,980 to £112,727 per QALY gained. Since the results from the ITC were considered by the ERG to be neither reliable nor robust, the ERG also considered a cost-effectiveness comparison to be inappropriate due to a lack of meaningful or reliable data. In spite of limitations in the data, the AC took the view that dabrafenib and vemurafenib were "likely" of similar clinical effectiveness. Since the overall costs of these two drugs were similar, the AC recommended the use of dabrafenib in patients with unresectable, advanced or metastatic BRAF V600 mutation-positive melanoma.

    The sentinel lymph node (SLN) is the first node in a nodal basin to receive the direct lymphatic flow from a malignant melanoma. However, in some patients, lymphoscintigraphic study reveals the presence of lymphatic nodes in the area between the primary melanoma and the regional basin. These nodes are called ''in-transit nodes'' or ''interval nodes'' and, by definition, are also SLNs. The purpose of this study was to determine the incidence and location of in-transit SLNs in patients with malignant melanoma and to assess whether it is really necessary to harvest them. The evaluation involved 600 consecutive malignant melanoma patients. Lymphoscintigraphy was performed on the day before surgery following intradermal injection of 74-111 MBq of 99m Tc-nanocolloid in four doses around the primary melanoma or the biopsy scar. Dynamic and static images were obtained and revealed SLNs in 599 out of 600 patients. The SLN was intraoperatively identified with the aid of patent blue dye and a hand-held gamma probe. Lymphoscintigraphy showed in-transit SLNs in 59/599 patients (9.8%). During surgery, all these in-transit SLNs were harvested, with those in the popliteal and epitrochlear regions being the most difficult to identify and excise. Metastatic cell deposits were subsequently identified in ten (16.9%) of these in-transit SLNs. In conclusion, lymphoscintigraphy has a key role in the identification of in-transit SLNs. Although the incidence of these nodes is relatively low in malignant melanoma patients, such SLNs present metastatic deposits in a significant percentage of cases and therefore the identification of in-transit SLNs in these patients is really necessary.

This study examined a model of clinical care developed by the High Risk Clinic (HRC) of the Sydney Melanoma Diagnostic Centre in relation to patient satisfaction. Semi-structured telephone interviews were conducted and analyzed using the framework of Miles and Huberman, and themes were organized using the qualitative software package, QSR NVivo8. Twenty HRC patients participated in the study (nine men, 11 women; mean age 57.6 years, age range 34-74 years; response rate 91%). Satisfaction with clinical care at the HRC was high. Factors contributing to patient satisfaction included: rapid and regular access to physicians who were perceived by participants as experts, the development of confidence and trust in one's treating doctor, and a sense of being cared about and understood by one's healthcare team. Although one-third of the participants reported some inconveniences in attending the clinic, these were viewed as minor difficulties and not significant barriers to care. Formal psychological support was not sought or expected by participants, although many expressed long-standing melanoma-related fears and concerns. Accessible, expert medical attention, delivered in a patient-centered manner was integral to melanoma survivors' satisfaction with clinical management. Appropriate referrals to psychological support may further increase satisfaction with clinical care. Copyright © 2013 John Wiley & Sons, Ltd.

    Full Text Available Objective. Thyroid disease has been reported among the endocrinopathies that can occur after treatment with ipilimumab. Graves’ disease, however, has been rarely reported with this medication. Here we report a case of Graves’ disease diagnosed after initiation of ipilimumab in a patient with melanoma. Methods. We present the clinical presentation and management course of this patient followed by a related literature review. Results. A 67-year-old male with metastatic melanoma was started on ipilimumab. He developed hyperthyroidism after two doses of ipilimumab. The cause of hyperthyroidism was determined to be Graves’ disease. Ipilimumab was held and the patient was started on methimazole with return to euthyroid status. Ipilimumab was resumed and the patient continued methimazole during the course of ipilimumab therapy, with controlled hyperthyroidism. Restaging studies following four cycles of ipilimumab showed complete response in the lungs, with residual melanoma in the neck. The patient then underwent total thyroidectomy and left neck dissection as a definitive treatment for both hyperthyroidism and residual melanoma. Conclusion. Graves’ disease can develop after starting ipilimumab and methimazole can be an effective treatment. For patients whose hyperthyroidism is well-controlled on methimazole, ipilimumab may be resumed with close monitoring.

    The impact of ethnicity and the socioeconomic status (SES) among Caucasians is not well studied. Here, we examine the impact of income on melanoma presentation and prognosis within a Caucasian cohort, accounting for ethnicity, as some reports suggest increased melanoma incidence in Ashkenazi Jewish (AJ) BRCA mutation carriers. We studied prospectively enrolled primary melanoma patients at New York University. SES data were estimated using United States' Census Bureau data and patient zip codes. We evaluated associations between ethnicity, SES, and baseline characteristics using the χ² test and multivariate logistic regression. We compared survival distributions using Kaplan-Meier curves, log-rank tests, and Cox proportional hazard ratios. Of the 1,339 enrolled patients, AJ represented 32% (n = 423). Apart from AJ being older at presentation (p < 0.001), no significant differences were observed in baseline characteristics between ethnic groups. Patients with a median household income (MHI) lower than the median of the cohort were significantly more likely to present with advanced stages (p < 0.001) compared to patients with a higher MHI. Shorter overall (p = 0.016) and post-recurrence survival (p = 0.042) was also observed in patients from lower-income households. Data suggest that disparities in melanoma presentation in Caucasians stratify according to income independent of ethnic background. © 2016 S. Karger AG, Basel.

    Recent NMR spectroscopy developments, such as high-resolution magic angle spinning (HRMAS) probes and correlation-enhanced 2D sequences, now allow improved investigations of phospholipid (Plp) metabolism. Using these modalities we previously demonstrated that a mouse-bearing melanoma tumor responded to chloroethyl nitrosourea (CENU) treatment in vivo by altering its Plp metabolism. The aims of the present study were to investigate whether HRMAS proton total correlation spectroscopy (TOCSY) could be used as a quantitative technique to probe Plp metabolism, and to determine the Plp metabolism response of cultured B16 melanoma cells to CENU treatment in vitro. The exploited TOCSY signals of Plp derivatives arose from scalar coupling among the protons of neighbor methylene groups within base headgroups (choline and ethanolamine). For strongly expressed Plp derivatives, TOCSY signals were compared to saturation recovery signals and demonstrated a linear relationship. HRMAS proton TOCSY was thus used to provide concentrations of Plp derivatives during long-term follow-up of CENU-treated cell cultures. Strong Plp metabolism alteration was observed in treated cultured cells in vitro involving a down-regulation of phosphocholine, and a dramatic and irreversible increase of phosphoethanolamine. These findings are discussed in relation to previous in vivo data, and to Plp metabolism enzymatic involvement. Copyright 2003 Wiley-Liss, Inc.

  5. Relationship Between LAPTM4B Gene Polymorphism and Susceptibility of Malignant Melanoma in Chinese Patients

    Full Text Available Lysosomal-associated protein transmembrane 4 beta (LAPTM4B is known as an oncogene associated with many human malignant tumors. There are two alleles of the gene, LAPTM4B*1 and LAPTM4B*2. Previous studies have shown that LAPTM4B polymorphism contributes to the risk of many cancers. This case-control study was to investigate the relationship between LAPTM4B gene polymorphism and susceptibility of malignant melanoma. The genotypes of LAPTM4B were determined in 617 control subjects and 220 patients with malignant melanoma by utilizing polymerase chain reaction based on specific primers. The genotypic distribution of LAPTM4B and Hardy–Weinberg equilibrium were analyzed by χ2 test. Odds ratio and 95% confidence interval was calculated by unconditional logistic regression. The distributions of LAPTM4B genotypes were significantly different between melanoma patients (45.9% for *1/1, 46.4% for *1/2 and 7.7 for *2/2 and controls (54.5% for *1/1, 39.9% for *1/2 and 5.7 for *2/2. LAPTM4B *1/2 and LAPTM4B *2/2 had a 1.396-fold and 1.619-fold higher risk for melanoma occurrence than *1/1, and subjects with LAPTM4B*2 have a 1.308-fold higher risk than LAPTM4B*1 carriers. No association between LAPTM4B genotypes and gender, age, subtype, Clark level of invasion, Breslow thickness, ulceration, clinical stage, and C-KIT, BRAF gene mutation status was observed. LAPTM4B*2 is associated with the high risk of malignant melanoma and carrying LAPTM4B *2 may be a susceptible factor to Chinese melanoma patients.

    The role of sentinel lymph node status (SLNS) in thick melanoma is evolving. The purpose of this study was to determine the prognostic value of SLNS in thick melanoma. A retrospective analysis of 120 prospectively collected clinically node-negative thick melanomas over 5 years was performed. Patient (age/sex) and tumor (thickness, ulceration, SLNS, mitoses, metastases, and recurrence) features were collected. Multivariate analysis was performed using Cox proportional hazard model. Factors predictive of positive SLN included male sex, ulceration, and high mitoses. Factors associated with positive SLN had higher local-regional recurrence and metastases than negative SLN. SLNS and tumor thickness impacted 5-year disease-free survival (DFS) and overall survival (OS). Positive SLN, ulceration, age, and mitoses were independent predictors of DFS/OS. Nonulcerated/lower mitoses thick melanomas had lower positive SLN rates. Positive SLN develop recurrence and metastases and have worse OS/DFS. SLNS is an important prognosticator for OS/DFS. Sentinel lymph node biopsy delineates prognostic groups in thick melanomas and can impact management. Copyright © 2014 Elsevier Inc. All rights reserved.

    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.

    2003-08-01

    To describe time trends, from 1987 through 1997, (1) in size of choroidal melanoma among patients with recent diagnosis confirmed at a clinical center that participated in the Collaborative Ocular Melanoma Study (COMS) and (2) in choice of treatment by patients who did not enroll in one of the COMS randomized trials. Investigators at all COMS clinical centers (41 in the United States and 2 in Canada) agreed to report, in a masked fashion that did not include personal identifiers, all patients diagnosed as having choroidal melanoma during the accrual period for COMS randomized trials of radiotherapy. Information reported for patients who did not enroll in a COMS randomized trial included tumor dimensions, date of diagnosis, and initial treatment selected. Patients reported by centers that continued to report cases until 1997 and diagnosed as having choroidal melanoma no more than 1 year before evaluation at a participating COMS center contributed the data analyzed. Time trends in tumor size among patients reported and in elective treatment of patients not enrolled in COMS randomized trials. Of 8712 patients with choroidal melanoma examined, 6703 met criteria for analysis of time trend in tumor size and 4077 were analyzed for treatment trends over time. The number of cases with longest tumor basal diameter greater than 15.0 mm declined over time from 393 (30%) of 1330 cases reported in 1987 through 1989 to 345 (25%) of 1397 cases reported in 1996 or 1997. The proportion of patients eligible for COMS randomized trials who did not enroll and who elected enucleation remained stable over time for tumors of all sizes; the proportion of these patients who elected eye-conserving radiotherapy increased over time. Juxtapapillary tumors accounted for nearly half of the enucleations among ineligible patients who had tumors no larger than 15.0 mm in longest basal diameter. Among patients examined at COMS centers during 1987 through 1997, the trends observed for patients with

    2018-01-01

    Full Text Available Simultaneous or sequential, planned administration of ipilimumab could significantly enhance the antitumor effects of nivolumab in advanced melanoma patients. On the other hand, the efficacy of ipilimumab for nivolumab-resistant advanced melanoma is extremely poor. Therefore, additional supportive therapy for anti-PD-1 antibody therapy-resistant advanced melanoma has been widely investigated. In this report, we describe a case of multiple in-transit melanomas developing in a nivolumab-resistant patient successfully treated with ipilimumab in combination with imiquimod. Our present case suggested a possible therapy for nivolumab-resistant multiple in-transit melanomas using ipilimumab in combination with topical imiquimod.

    Full Text Available Background and Design: Dermoscopy has an important role in the diagnosis of melanoma nowadays. Dermoscopic findings of melanoma had been associated with Breslow thickness and invasion status in previous studies but the relationship between dermatoscopic findings and other histopathological prognostic indicators has not been investigated until today. In this study, our aim is to investigate the relationship between dermatoscopic findings and histopathologic prognostic indicators such as Breslow thickness, invasion status, mitotic rate, lymphovascular invasion (LVI, ulceration and regression in patients who had been diagnosed with melanoma due to their clinical, dermatoscopic and histopatological findings. Materials and Methods: Dermoscopic and histopathological findings of 47 cases of melanoma who applied to our clinic between the years 2000 and 2014 were evaluated. The relationship between the dermoscopic findings which had been reported to be observed in melanomas in previous research and the histopathologic prognostic indicators such as Breslow thickness, invasion status, mitotic rate, lymphovascular invasion, ulceration and regression were investigated. Results: Irregular dots/globules, atypical pigment network, multifocal hypopigmentation, radial streaks and moth-eaten borders have been associated with good prognostic indicators whereas comedo like openings, regular blotch, exophytic papillary structures, dotted, glomerular, lineer irregular vessels, pink/red and blue/gray colors were associated with poor prognostic indicators. Additionally some dermatoscopic findings which are more observed in benign lesions such as multiple milia-like cysts, comedo like openings, moth-eaten borders, regular blotch, exophytic papillary structures and finger print areas have been observed in melanomas in our study. Conclusion: Many dermoscopic findings have demonstrated statistically significant association with the histopathological prognostic indicators

    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.

    It is the purpose of the study to assay the possibilities of lymphoscintigraphy (LS) in evaluating local lymphatic drainage and sentinel lymph nodes (SLNs) location in patients presenting breast carcinoma and malignant melanoma. Twenty-nine women with breast carcinoma (TI-IIa clinical stage, age range 31 to 74 y) and 7 patients with malignant melanoma (Clark III-V) are scanned in the period 1997 through 1998. 99m Tc-sulphur colloid (Solco Lymphoscint, SORIN) with mean size of particles 50 nm is used. Planar images are obtained at 20 and 120-180 min after sc injection in the region of primary tumor, at mean radioactivity 20 MBq per injection site in a volume 0.2-0.3 ml. In the breast cancer patients Patent Blue V or Mitoxantrone is injected around the tumor twice - 20 and 3 to 1/2 hours prior to surgery. In malignant melanoma patients immunoscintigraphy using 740 MBq 99m Tc-anti-melanoma monoclonal antibodies (Technemab-K-1) is carried out before lymph node dissection. SLNs are visualized in 25 patients (86.2%) with breast cancer. In 21 (72%) patients to 4 SLNs are scanned in level I of the local axillary region, in 4 cases (14%) - in the region of axillary level II, in one female patient (3%) - at axillary level III, and in 3 patients (10%) i psilateral internal mammary lymph nodes are scanned. Two patients are suspected for the so-called s kip t ype of tumor lymphatic dissemination. In 4 patients no SLN images are visible. In breast carcinoma patients SLN are additionally stained blue and following intraoperative revision, evidence of metastatic involvement is established in 12 instances (41.3%). In 3 patients with melanoma in the abdomen and back SLNs are located in the region of inguinal and axillary lymph node groups, while in 3 patients presenting lesions to the surface of extremities only local lymph nodes draining the melanoma are visualized. Immunoscintigraphy shows enhanced uptake in the region of SLNs in 3 cases with the metastatic changes in them

    Cerebral spinal fluid (CSF) from brain tumor patients contains tumor cellular and cell-free DNA (cfDNA), which provides a less-invasive and routinely accessible method to obtain tumor genomic information. In this report, we used droplet digital PCR to test mutant tumor DNA in CSF of a patient to monitor the treatment response of metastatic melanoma leptomeningeal disease (LMD). The primary melanoma was known to have a BRAFV600E mutation, and the patient was treated with whole brain radiotherapy and BRAF inhibitors. We collected 9 CSF samples over 6 months. The mutant cfDNA fraction gradually decreased from 53 % (time of diagnosis) to 0 (time of symptom alleviation) over the first 6 time points. Three months after clinical improvement, the patient returned with severe symptoms and the mutant cfDNA was again detected in CSF at high levels. The mutant DNA fraction corresponded well with the patient’s clinical response. We used whole exome sequencing to examine the mutation profiles of the LMD tumor DNA in CSF before therapeutic response and after disease relapse, and discovered a canonical cancer mutation PTENR130* at both time points. The cellular and cfDNA revealed similar mutation profiles, suggesting cfDNA is representative of LMD cells. This study demonstrates the potential of using cellular or cfDNA in CSF to monitor treatment response for LMD. PMID:26961773

    Despite the early notion that canine oral malignant melanoma is radioresistant, recent data suggest that external beam radiotherapy is effective in local tumor control. However, optimal fractionation schedules have not been established. The high rate of regional and distant metastasis is another problem that has hindered long-term control. The role of chemotherapy in the management of canine oral melanoma has also not been determined. In this study, data from 140 dogs irradiated at North Carolina State University were evaluated with the following objectives: (1) to compare the efficacy of three radiation therapy protocols (36 Gy, 9 Gy x 4 fractions; 30 Gy, 10 Gy x 3 fractions; or >45 Gy, 2-4 Gy x 12-19 fractions) for the treatment of dogs with oral malignant melanoma, (2) to identify any host or tumor factors influencing prognosis, and (3) to determine the impact of systemic chemotherapy on treatment outcome. Information regarding response to therapy, disease progression, and survival were determined from the medical records or from information obtained by telephone or mail survey. Relationships between host, tumor, and treatment variables and outcome measures (response, time to first event, and survival) were evaluated using Fisher's exact test (response) and the Cox regression model (time to first event and survival). The median time to first event for the 140 dogs was 5.0 months (95% C.I., 4-6 months) and the median survival was 7.0 months (95% C.I., 6-9 months). In the univariate analysis, the following variables were associated with increased time to first event and survival: (1) rostral tumor sublocation; (2) lack of bone lysis observed on skull imaging, and (3) microscopic tumor burden. In a multivariate analysis of 111 dogs with complete data for these variables, tumor sublocation, bone lysis, and tumor volume were identified as joint predictors of time to first event (p oral malignant melanoma; however, the optimal fractionation scheme has yet to be

    Science.gov (United States)

    2011-01-01

    Background Despite the increased level of familial risk, research indicates that family members of patients with melanoma engage in relatively low levels of sun protection and high levels of sun exposure. The goal of this study was to evaluate a broad range of demographic, medical, psychological, knowledge, and social influence correlates of sun protection and sunbathing practices among first-degree relatives (FDRs) of melanoma patients and to determine if correlates of sun protection and sunbathing were unique. Methods We evaluated correlates of sun protection and sunbathing among FDRs of melanoma patients who were at increased disease risk due to low compliance with sun protection and skin surveillance behaviors. Participants (N = 545) completed a phone survey. Results FDRs who reported higher sun protection had a higher education level, lower benefits of sunbathing, greater sunscreen self-efficacy, greater concerns about photo-aging and greater sun protection norms. FDRs who reported higher sunbathing were younger, more likely to be female, endorsed fewer sunscreen barriers, perceived more benefits of sunbathing, had lower image norms for tanness, and endorsed higher sunbathing norms. Conclusion Interventions for family members at risk for melanoma might benefit from improving sun protection self-efficacy, reducing perceived sunbathing benefits, and targeting normative influences to sunbathe.

    Extramammary Paget disease (EMPD) is a rare skin disease commonly found in the anogenital region. In this study, we aimed to identify EMPD patients seen in the non-melanoma skin cancer clinic at Odette Cancer Centre and to describe the treatments delivered and outcomes achieved. From 2000 to 2009, 14 patients were seen. Initial treatment recommendations included imiquimod and surgical excision, although half the patients required more than one treatment modality, highlighting the difficulty of achieving complete eradication of this disease.

    Conclusions: The published findings on gender disparities in melanoma have yielded many advances in our understanding of this disease. Biological, environmental, and behavioral factors may explain the observed gender difference in melanoma incidence and outcome. Further research will enable us to learn more about melanoma pathogenesis, with the goal of offering better treatments and preventative advice to our patients.

  2. Antibody Therapy Targeting CD47 and CD271 Effectively Suppresses Melanoma Metastasis in Patient-Derived Xenografts

    Directory of Open Access Journals (Sweden)

    Michael Ngo

    2016-08-01

    Full Text Available The high rate of metastasis and recurrence among melanoma patients indicates the existence of cells within melanoma that have the ability to both initiate metastatic programs and bypass immune recognition. Here, we identify CD47 as a regulator of melanoma tumor metastasis and immune evasion. Protein and gene expression analysis of clinical melanoma samples reveals that CD47, an anti-phagocytic signal, correlates with melanoma metastasis. Antibody-mediated blockade of CD47 coupled with targeting of CD271+ melanoma cells strongly inhibits tumor metastasis in patient-derived xenografts. This therapeutic effect is mediated by drastic changes in the tumor and metastatic site immune microenvironments, both of whichwhich exhibit greatly increased density of differentiated macrophages and significantly fewer inflammatory monocytes, pro-metastatic macrophages (CCR2+/VEGFR1+, and neutrophils, all of which are associated with disease progression. Thus, antibody therapy that activates the innate immune response in combination with selective targeting of CD271+ melanoma cells represents a powerful therapeutic approach against metastatic melanoma.

    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

    The last melanoma staging system of the 2009 American Joint Committee on Cancer takes into account, for stage IV disease, the serum levels of lactate dehydrogenase (LDH) and the site of distant metastases. Our aim was to compare the significance of metastatic volume, as evaluated at the time of stage IV melanoma diagnosis, with other clinical predictors of prognosis. We conducted a retrospective multicentric study. To establish which variables were statistically correlated both with death and survival time, contingency tables were evaluated. The overall survival curves were compared using the Kaplan-Meier method. Metastatic volume and number of affected organs were statistically related to death. In detail, patients with a metastatic volume >15 cm(3) had a worse prognosis than those with a volume lower than this value (survival probability at 60 months: 6.8 vs. 40.9%, respectively). The Kaplan-Meier method confirmed that survival time was significantly related to the site(s) of metastases, to elevated LDH serum levels and to melanoma stage according to the latest system. Our results suggest that metastatic volume may be considered as a useful prognostic factor for survival among melanoma patients.

    Neuroblastoma rat-sarcoma (NRAS) mutations have been described in Chinese patients with melanoma. However, the status and the clinical significance of NRAS gain have not been investigated on a large scale. A total of 657 melanoma samples were included in the study. NRAS copy number was examined using the QuantiGene Plex DNA assay. The sensitivities of cell lines and patient-derived xenograft (PDX) models containing NRAS gain to a MAP/ERK kinase (MEK) inhibitor (binimetinib) were also evaluated. The overall incidence of NRAS gain was 14.0% (92 of 657). Incidence of NRAS gain in acral, mucosal, chronic sun-induced damage (CSD) and non-CSD melanomas was 12.2%, 15.8%, 9.5% and 19.4%, respectively. NRAS gain was mutually exclusive to NRAS mutations (P = 0.036). The median survival time for melanoma patients with NRAS gain was significantly shorter than that for patients with normal NRAS copy number (P = 0.006). For patients containing NRAS gain, the median survival time for higher copy number (>4 copies) was significantly shorter than those with lower copy number (2-4 copies; P = 0.002). The MEK inhibitor (binimetinib) inhibited the proliferation of melanoma cells and the tumour growth of PDX models with NRAS gain. NRAS gain is frequent in patients with melanoma and may predict a poor prognosis of melanoma. The melanoma cells and PDX models containing NRAS gain are sensitive to MEK inhibitor (binimetinib), indicating that NRAS gain might be a new therapeutic target for melanoma.

    Malignant melanoma occurs not only in the skin but also in ocular tissues. Ocular melanoma located superficially as in conjunctiva can be treated successfully by BNCT. In the present study, we investigated 10 B dynamics in ocular melanoma and the surrounding normal tissues, to evaluate the possibility of applying BNCT to ocular melanoma. In three ocular melanoma patients, 10 B concentration in melanoma after administration of 10 B-BPA by oral or drip infusion ranged from 10.4 to 21.5 ppm. The boron concentrations in lens and vitreous body were lower than blood level, whereas higher than blood in sclera and palpebral skin. These results suggest that we can treat such a superficial melanoma lesions as conjunctival melanoma by BNCT using 10 B 1 -BPA. (author)

    Oral malignant melanomas carry a poor-to-guarded prognosis because of their local invasiveness and high metastatic propensity. The Oncept melanoma vaccine is licensed to treat dogs with stage II or III locally-controlled oral malignant melanoma and this retrospective study aimed to assess survival of affected dogs treated with the vaccine in the UK. Medical records of dogs with histopathologically-confirmed oral malignant melanoma that received the vaccine as part of their treatment were evaluated. Survival analyses for potential prognostic factors were performed. Sixty-nine dogs were included; 56 dogs, staged I to III, and with previous locoregional therapy, had a median survival time of 455 days (95% CI: 324 to 586 days). Based on Kaplan-Meier survival analysis with associated log-rank testing, no significant prognostic factors were identified for this population. Of the 13 patients with macroscopic disease treated with vaccine alone or in combination therapy, eight showed clinical response. Three patients with stage IV oral malignant melanoma survived 171, 178 and 288 days from diagnosis. Patients treated with the melanoma vaccine in our study had survival times similar to their counterparts receiving the vaccine in the USA. There were observed responses in patients with macroscopic disease and so the vaccine could be considered as palliative treatment in dogs with stage IV disease. © 2017 British Small Animal Veterinary Association.

    Full text: Small series have shown that PET scanning using F-18 fluorodeoxyglucose (FDG), can quite accurately stage patients melanoma. At this Institute these patients are only sent for PET imaging if they have high risk melanomas ( >3 Clarke's grade primaries) or there remains any significant doubt as to their clinical staging or management after the completion of conventional screening. This prospective study examines how PET scan findings influenced the clinical management decisions in 53 patients (29 males, mean age 54±13 yrs: range 31-81 yrs) Referring doctors were asked to indicate reason for the PET scan, stage their patients on the basis of all their current investigations, and to indicate their management plans prior to PET scanning. Follow-up of subsequent patient management at 2-4 weeks post PET scan was then obtained and compared to pre PET plans. PET was used to stage 26 patients, restage 17, follow-up 5, assess recurrence in 3, and other in 2 patients. To date follow-up has shown that in 32/49 (65%) patients PET was used to triage patients to locoregional surgery (10 patients), radical radiotherapy (5 patients), or to continuing follow-up only (17 patients). Three further high risk patients with negative PET scans had sentinel mode biopsy. In only 13 patients was management already determined, with planned treatment being changed in 6. Four patients have not had their post PET scan review yet. To date proven false negative PET scans have occurred in 3 cases, 2 sentinel node biopsies showed microscopic disease, and one scan incorrectly labelled gall-bladder melanoma as hydro-nephrotic kidney. Interestingly in 3 cases, PET discovered other unsuspected tumours (rectum x 2, plasmacytoma). PET scanning has been incorporated into routine management to triage most high risk patients, but it still alters interventions in half of those patients where management has already been planned. PET clearly misses small volume disease, the importance of which is

    Informing and educating melanoma patients is important for early detection of a recurrence or second primary. This study aimed to investigate Dutch melanoma patients' disease-specific knowledge, and their opinions on information provision and the value of e-Health videos. All AJCC stage I-II melanoma patients in follow-up between March 2015 and March 2016 at a single melanoma center were invited to complete 19 online questions, addressing respondents' characteristics, knowledge on melanoma, and opinions on melanoma-specific information received and the educational YouTube videos. In total, 100 patients completed the survey (response = 52%); median age was 60 years and 51% were female. Breslow tumor thickness was unknown by 34% and incorrectly indicated by 19%, for presence of ulceration this was 33% and 11%, for mitosis 65% and 14%, and for AJCC stage 52% and 23%, respectively. Only 5% correctly reproduced all four tumor characteristics. Orally delivered information regarding warning signs, severity, treatment possibilities, and importance of self-inspection was clearest for patients, compared to information in the melanoma brochure. According to 77% of patients, YouTube videos regarding self-inspection of the skin and regional lymph nodes had additional value. Altogether, 63% preferred receiving information in multiple ways; 92% orally by their physician, 62% through videos, and 43% through brochures. Patients' melanoma-specific knowledge appears to be limited. There is an urgent need for further improvement of providing information and patient education. In addition to oral and written information, e-Health videos seem to be a convenient supplemental and easy accessible method for patient education.

  13. A patient with metastatic melanoma presenting with gastrointestinal perforation after dacarbazine infusion: a case report

    Directory of Open Access Journals (Sweden)

    Hospers Geke AP

    2010-01-01

    Full Text Available Abstract Introduction We report a rare case of gastrointestinal perforation following dacarbazine infusion for metastatic melanoma. The condition is attributed to a responding malignant melanoma in the gastrointestinal tract. Case presentation A 52-year-old Caucasian man presented with abdominal pain and distension, malaise, night sweats, dysphagia and early satiety. A computed tomography scan showed massive ascites, lymphadenopathy and liver lesions suspect for metastases. An upper gastrointestinal endoscopy was performed and revealed multiple dark lesions of 5 mm to 10 mm in his stomach and duodenum. When his skin was re-examined, an irregular pigmented lesion over the left clavicle measuring 15 mm × 8 mm with partial depigmentation was found. Histological examination of a duodenal lesion was consistent with a diagnosis of metastatic melanoma. The patient deteriorated and his level of lactate dehydrogenase rapidly increased. The patient was started on systemic treatment with dacarbazine 800 mg/m2 every three weeks and he was discharged one day after the first dose. On the sixth day he was readmitted with severe abdominal pain. A chest X-ray showed the presence of free intraperitoneal air that was consistent with gastrointestinal perforation. His lactate dehydrogenase level had fallen from 6969U/L to 1827U/L, supporting the conclusion that the response of gastrointestinal metastases to dacarbazine had resulted in the perforation of the patient's bowel wall. A laparotomy was discussed with the patient and his family but he decided to go home with symptomatic treatment. He died 11 days later. Conclusion Melanoma can originate in, as well as metastasize to, the gastrointestinal tract. Gastrointestinal perforations due to responding tumors are a well-known complication of systemic treatment of gastrointestinal lymphomas. However, as the response rate of metastatic melanoma to dacarbazine is only 10% to 20%, and responses are usually only partial

    The aim of this study was to investigate the rate of monosomy 3 by CISH technique in Iranian patients with uveal melanoma (UM) and its correlation with clinical and histopathological features. Archival formalin fixed, paraffin-embedded material from 50 patients who had undergone enucleation for large uveal melanomas was obtained. Monosomy of chromosome 3 alteration by chromogenic in situ hybridization (CISH) was investigated. Clinical and histopathological features of tumors were collected. The patients had a mean age of 56.6±7.6 years. Mean basal diameter and thickness of tumors were 14.1 mm and 10.2 mm, respectively. Four patients (8%) were identified to harbor monosomy of chromosome 3. In the mean follow-up of 5.3 years (range, 3.2-9.5 y), only one case with monosomy 3 died of UM metastasis. The most common type of cellularity was mixed cell (86%). There was not any statistically significant correlation between monosomy of chromosome 3 and type of cellularity, ciliary body involvement, and largest basal diameter. The low rate of monosomy chromosome 3 and the consequent low rate of mortality may be indicative of good prognosis in Iranian patients with uveal melanoma.

    2012-08-01

    Full Text Available Abstract Background Adoptive cell therapy may be based on isolation of tumor-specific T cells, e.g. autologous tumor infiltrating lymphocytes (TIL, in vitro activation and expansion and the reinfusion of these cells into patients upon chemotherapy induced lymphodepletion. Together with high-dose interleukin (IL-2 this treatment has been given to patients with advanced malignant melanoma and impressive response rates but also significant IL-2 associated toxicity have been observed. Here we present data from a feasibility study at a Danish Translational Research Center using TIL adoptive transfer in combination with low-dose subcutaneous IL-2 injections. Methods This is a pilot trial (ClinicalTrials.gov identifier: NCT00937625 including patients with metastatic melanoma, PS ≤1, age Results Low-dose IL-2 considerably decreased the treatment related toxicity with no grade 3–4 IL-2 related adverse events. Objective clinical responses were seen in 2 of 6 treated patients with ongoing complete responses (30+ and 10+ months, 2 patients had stable disease (4 and 5 months and 2 patients progressed shortly after treatment. Tumor-reactivity of the infused cells and peripheral lymphocytes before and after therapy were analyzed. Absolute number of tumor specific T cells in the infusion product tended to correlate with clinical response and also, an induction of peripheral tumor reactive T cells was observed for 1 patient in complete remission. Conclusion Complete and durable responses were induced after treatment with adoptive cell therapy in combination with low-dose IL-2 which significantly decreased toxicity of this therapy.

    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.

    Sun exposure is known to cause melanoma; what is not known is whether patients from the Southern United States have a different profile of clinicopathologic factors and outcomes than those from the Northern United States. Data from a prospective, randomized trial on surgery for cutaneous melanoma were analyzed. All patients underwent wide excision and sentinel lymph node biopsy. Patients were categorized into two groups: Northern or Southern according to their state of residence. Clinicopathologic factors and outcomes were compared between groups. A total of 2025 patients were included in the analysis; 1214 (60%) were from Southern states. The median follow-up was 52 months. Despite significant differences in clinicopathologic features between groups on both univariate and multivariate analysis, two important factors, namely primary tumor thickness and ulceration were not different, nor was the rate of lymph node metastasis. Additionally, there were no differences in disease-free survival or overall survival between the two groups. Significant differences exist between primary melanomas based on geographic regions; however there are no differences in survival. Cumulative versus episodic sun exposure may play some role in these differences.

    Autologous monocyte-derived dendritic cells (DCs) electroporated with synthetic mRNA (TriMixDC-MEL) are immunogenic and have antitumor activity as a monotherapy in patients with pretreated advanced melanoma. Ipilimumab, an immunoglobulin G1 monoclonal antibody directed against the cytotoxic T-lymphocyte-associated protein 4 receptor that counteracts physiologic suppression of T-cell function, improves the overall survival of patients with advanced melanoma. This phase II study investigated the combination of TriMixDC-MEL and ipilimumab in patients with pretreated advanced melanoma. Thirty-nine patients were treated with TriMixDC-MEL (4 × 10(6) cells administered intradermally and 20 × 10(6) cells administered intravenously) plus ipilimumab (10 mg/kg every 3 weeks for a total of four administrations, followed by maintenance therapy every 12 weeks in patients who remained progression free). Six-month disease control rate according to the immune-related response criteria served as the primary end point. The 6-month disease control rate was 51% (95% CI, 36% to 67%), and the overall tumor response rate was 38% (including eight complete and seven partial responses). Seven complete responses and one partial tumor response are ongoing after a median follow-up time of 36 months (range, 22 to 43 months). The most common treatment-related adverse events (all grades) consisted of local DC injection site skin reactions (100%), transient post-DC infusion chills (38%) and flu-like symptoms (84%), dermatitis (64%), hepatitis (13%), hypophysitis (15%), and diarrhea/colitis (15%). Grade 3 or 4 immune-related adverse events occurred in 36% of patients. There was no grade 5 adverse event. The combination of TriMixDC-MEL and ipilimumab is tolerable and results in an encouraging rate of highly durable tumor responses in patients with pretreated advanced melanoma. © 2016 by American Society of Clinical Oncology.

  2. Elevated Levels of SOX10 in Serum from Vitiligo and Melanoma Patients, Analyzed by Proximity Ligation Assay.

    Directory of Open Access Journals (Sweden)

    Andries Blokzijl

    Full Text Available The diagnosis of malignant melanoma currently relies on clinical inspection of the skin surface and on the histopathological status of the excised tumor. The serum marker S100B is used for prognostic estimates at later stages of the disease, but analyses are marred by false positives and inadequate sensitivity in predicting relapsing disorder.To investigate SOX10 as a potential biomarker for melanoma and vitiligo.In this study we have applied proximity ligation assay (PLA to detect the transcription factor SOX10 as a possible serum marker for melanoma. We studied a cohort of 110 melanoma patients. We further investigated a second cohort of 85 patients with vitiligo, which is a disease that also affects melanocytes.The specificity of the SOX10 assay in serum was high, with only 1% of healthy blood donors being positive. In contrast, elevated serum SOX10 was found with high frequency among vitiligo and melanoma patients. In patients with metastases, lack of SOX10 detection was associated with treatment benefit. In two responding patients, a change from SOX10 positivity to undetectable levels was seen before the response was evident clinically.We show for the first time that SOX10 represents a promising new serum melanoma marker for detection of early stage disease, complementing the established S100B marker. Our findings imply that SOX10 can be used to monitor responses to treatment and to assess if the treatment is of benefit at stages earlier than what is possible radiologically.

    Adoptive cell therapy with autologous tumor-infiltrating lymphocytes (TIL) and high-dose interleukin-2 (IL-2), after nonmyeloablative chemotherapy, has been shown to result in tumor regression in half of refractory metastatic melanoma patients. In the present study, we describe 2 separate clinical protocols. Twelve patients were treated with "Selected"-TIL, as previously reported and 8 patients with the modified version of "Young"-TIL. Selected-TIL protocol required the establishment of multiple T-cell cultures from 1 patient and in vitro selection of cultures secreting interferon-gamma upon antigenic stimulation. In contrast, Young-TIL are minimally cultured T cells with superior in vitro features that do not require further selection. Two of 12 Selected-TIL patients experienced objective clinical responses (1 complete response, 1 partial response). Out of 8 treated Young-TIL patients, 1 experienced complete response, 2 partial response, and 4 patients had disease stabilization. Twenty-one of 33 enrolled Selected-TIL patients were excluded from the protocol, mainly as cultures failed the interferon-gamma selection criteria or due to clinical deterioration, compared with only 3 Young-TIL patients. Expected bone marrow suppression and high-dose IL-2 toxicity were transient. There was no treatment-related mortality. This study vindicates the feasibility and effectiveness of TIL technology and calls for further efforts to implement and enhance this modality. The use of minimally cultured, unselected Young-TIL enables the treatment of most enrolled patients. Although the cohort of Young-TIL patients treated so far is rather small and the follow-up short, the response rate is encouraging.

    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.

    OBJECTIVE: The aim of this study was to review the outcome of sentinel lymph node biopsy (SLNB) in patients with melanoma and to delineate whether patients with nodular melanoma are more likely to develop nodal recurrence despite negative SLNB. METHODS: Consecutive patients with cutaneous melanoma undergoing SLNB were identified from a departmental database between 1997 and 2005. Factors including demographic data, site, histological subtype, depth and outcome were examined. RESULTS: Of 131 patients, 103 were node negative and eligible for study. The median age was 53 (16-82) years with 46 patients being male (45%) and 57 female (55%). Primary melanoma sites included lower limb (49; 48%), upper limb (29; 28%), head (12; 11%), trunk (7; 7%) and back (6; 6%). The median Breslow thickness was 2mm. Superficial spreading accounted for 43% of melanoma with nodular accounting for 42%. Median follow-up was 40 (3-90) months. Of 20 relapses, seven recurred in the same nodal basin, three were satellite recurrences, one recurred with both satellite and nodal lesions simultaneously, and nine experienced haematogenous spread. Of the eight patients who developed recurrence in the same nodal basin, four were of nodular histological subtype (p=NS). All of the three patients with satellite lesions had nodular melanoma histologically (p=0.02). When nodal and satellite recurrences were combined, eight of 11 were histologically nodular (p=0.01). CONCLUSIONS: This study indicates that lymphatic recurrence occurs more often in SLNB negative patients with nodular melanoma. Further evaluation of the inclusion criteria for sentinel node biopsy is warranted.

    The aim of this study was to assess the added benefit of whole-body (head-to-toes) PET/CT versus routine 'eyes-to-thighs' PET/CT of melanoma and sarcoma patients. We performed a retrospective review of consecutive whole-body PET/CT scans from January 2006 through December 2010 in patients with melanoma or sarcoma. PET abnormalities in the brain, distal thighs, and legs were recorded and clinical significance was assessed on the basis of pathology, imaging studies, and clinical follow-up. Patients with known primary lesions distal to the proximal femora were excluded as these patients would routinely undergo 'head-to-toe' PET/CT. We reviewed reports from 352 PET/CT examinations in 194 patients with melanoma and 75 PET/CT examinations in 44 patients with sarcoma. Melanoma: 13 patients had brain metastases on PET. In five of these patients, lesions were unknown, but all were in the setting of other metastatic disease. Twenty-seven patients had lower extremity metastases, all in the setting of other metastatic disease. No lower extremity metastases were found in the remaining 167 patients. Sarcoma: one patient had an isolated, unexpected brain metastasis. Six patients had leg metastases, but none were isolated. No lower extremity metastases were found in the remaining 38 patients. In patients with melanoma and sarcoma, inclusion of entire lower extremities adds little additional clinical value as detection of isolated, unexpected metastasis is rare. Brain imaging may add value as the presence of brain metastases alters clinical management. Overall, in patients with melanoma or sarcoma, whole-brain PET/CT imaging may be of value, but routine inclusion of the entire lower extremities adds little additional value.

    Melanoma patients exhibit changes in immune responsiveness in the local tumor environment, draining lymph nodes, and peripheral blood. Immune-targeting therapies are revolutionizing melanoma patient care increasingly, and studies show that patients derive clinical benefit from these newer agents. Nonetheless, predicting which patients will benefit from these costly therapies remains a challenge. In an effort to capture individual differences in immune responsiveness, we are analyzing patterns of gene expression in human peripheral blood cells using RNAseq. Focusing on CD4+ peripheral blood cells, we describe multiple categories of immune regulating genes, which are expressed in highly ordered patterns shared by cohorts of healthy subjects and stage IV melanoma patients. Despite displaying conservation in overall transcriptome structure, CD4+ peripheral blood cells from melanoma patients differ quantitatively from healthy subjects in the expression of more than 2000 genes. Moreover, 1300 differentially expressed genes are found in transcript response patterns following activation of CD4+ cells ex vivo, suggesting that widespread functional discrepancies differentiate the immune systems of healthy subjects and melanoma patients. While our analysis reveals that the transcriptome architecture characteristic of healthy subjects is maintained in cancer patients, the genes expressed differentially among individuals and across cohorts provide opportunities for understanding variable immune states as well as response potentials, thus establishing a foundation for predicting individual responses to stimuli such as immunotherapeutic agents.

Intravenous administration of nivolumab was approved for the treatment of unresectable malignant melanoma in 2014 in Japan. When advanced melanoma patients were treated with nivolumab, median overall survival became longer. Overall survival rate was significantly better in nivolumab-treated melanoma patients than dacarbazine-treated melanoma patients. Nivolumab had an acceptable long-term tolerability profile, with 22% of patients experiencing grade 3 or 4 adverse events related to the drug. Therefore, nivolumab can become an alternative therapy for advanced malignant melanoma. Keywords: monoclonal antibody, PD-1, PD-L1

    Cultured fibroblasts of 17 first-degree relatives of familial melanoma patients and six first-degree relatives of cutaneous melanoma (CMM) patients with multiple CMM primaries were tested for in vitro sensitivity to UV light. Fibroblasts of nine familial CMM patients with a known UV-sensitivity and 19 healthy probands served as a control. Sister chromatid exchange (SCE) was used as a parameter to detect UV-induced genotoxic damage. The authors found significantly (p less than 0.001) increased UV-induced SCE levels in familial melanoma patients, as well as in first-degree relatives of familial melanoma patients (p less than 0.001) after UV-A,B irradiation (375 J/m2), compared to the healthy probands without a family history of CMM. A significant (p less than 0.001) increase of UV-induced SCE was also observed in the relatives of CMM patients with multiple CMM primaries. In addition, the spontaneous SCE were significantly increased (p less than 0.05) in familial CMM patients. This study shows that increased UV sensitivity is a familial phenomenon. It is consistent with the concept of a genetic predisposition to CMM, which is based on increased UV sensitivity and may help to define groups with an elevated risk of developing cutaneous malignant melanoma

    Full Text Available Abstract Background Different Insulin-like Growth Factor Binding Proteins (IGFBPs have been investigated as potential biomarkers in several types of tumors. In this study, we examined both IGFBP-3 and -4 levels in tissues and sera of melanoma patients representing different stages of melanoma progression. Methods The study cohort consisted of 132 melanoma patients (primary, n = 72; metastatic, n = 60; 64 Male, 68 Female; Median Age = 56 prospectively enrolled in the New York University School of Medicine Interdisciplinary Melanoma Cooperative Group (NYU IMCG between August 2002 and December 2006. We assessed tumor-expression and circulating sera levels of IGFBP-3 and -4 using immunohistochemistry and ELISA assays. Correlations with clinicopathologic parameters were examined using Wilcoxon rank-sum tests and Spearman-rank correlation coefficients. Results Median IGFBP-4 tumor expression was significantly greater in primary versus metastatic patients (70% versus 10%, p = 0.01 A trend for greater median IGFBP-3 sera concentration was observed in metastatic versus primary patients (4.9 μg/ml vs. 3.4 μg/ml, respectively, p = 0.09. However, sera levels fell within a normal range for IGFBP-3. Neither IGFBP-3 nor -4 correlated with survival in this subset of patients. Conclusion Decreased IGFBP-4 tumor expression might be a step in the progression from primary to metastatic melanoma. Our data lend support to a recently-described novel tumor suppressor role of secreting IGFBPs in melanoma. However, data do not support the clinical utility of measuring levels of IGFBP-3 and -4 in sera of melanoma patients.

    Epidemiological features and trends of cutaneous melanoma (CM) in North-African populations remain unclear. Those populations are of particular interest as they belong to a mosaic of various other origins (sub-Saharan, European Ancestry, and North-African Berbers). The aim of this study is to draw epidemiological profile and clinicopathological features of CM in the Tunisian population. Incidence analyses were based on data from regional cancer registries. Clinical data were collected from dermatological departments and xeroderma pigmentosum (XP) referral centers and provided CM clinicopathological characteristics and progression. Statistical analyses were achieved using R packages and SPSS 20.0. The incidence of CM in Tunisia is relatively low (0.5-0.7 per 100,000 inhabitants per year). Gender differences were observed regarding anatomical distribution (P = 0.004). Acral lentiginous melanoma (ALM) was the most frequent histological subtype (32.3%); however, nodular melanoma (NM) was the most aggressive and responsible for 54.8% of deaths. CM in XP patients develops at a median age that is 42 years earlier than sporadic cases, with preferential localization on the head and neck (P Xeroderma pigmentosum stands as the major predisposing host factor. © 2016 The International Society of Dermatology.

    Full Text Available The aim of this case-case study was to determine the differences between dysplastic and common naevus-associated melanomas (NAM and de novo melanomas. A total of 1,021 prospectively collected patients with invasive cutaneous melanoma from an oncology referral centre were included in the study. Of these, 75.51% had de novo melanomas, 12.93% dysplastic NAM, and 11.56% common NAM. Dysplastic NAM, compared with de novo melanomas, were associated with intermittently photo-exposed sites, atypical melanocytic naevi, decreased tumour thickness, and presence of MC1R non-synonymous variants. Common NAM were more frequent on the trunk and of superficial spreading type. Comparison of dysplastic with common NAM showed significant difference only with regard to mitoses. Both subtypes of NAM shared less aggressive traits than de novo melanomas, albeit with no significant differences in survival after multivariate adjustment. In conclusion, NAM present with less aggressive traits, mostly due to a greater awareness among patients of changing moles than due to their intrinsic biological characteristics.

    Purpose Up to 50% of patients with uveal melanoma (UM) develop metastatic disease with limited treatment options. The immunomodulating agent ipilimumab has shown an overall survival (OS) benefit in patients with cutaneous metastatic melanoma in two phase III trials. As patients with UM were excluded in these studies, the Dermatologic Cooperative Oncology Group (DeCOG) conducted a phase II to assess the efficacy and safety of ipilimumab in patients with metastatic UM. Patients and Methods We undertook a multicenter phase II study in patients with different subtypes of metastatic melanoma. Here we present data on patients with metastatic UM (pretreated and treatment-naïve) who received up to four cycles of ipilimumab administered at a dose of 3 mg/kg in 3 week intervals. Tumor assessments were conducted at baseline, weeks 12, 24, 36 and 48 according to RECIST 1.1 criteria. Adverse events (AEs), including immune-related AEs were graded according to National Cancer Institute Common Toxicity Criteria (CTC) v.4.0. Primary endpoint was the OS rate at 12 months. Results Forty five pretreated (85%) and eight treatment-naïve (15%) patients received at least one dose of ipilimumab. 1-year and 2-year OS rates were 22% and 7%, respectively. Median OS was 6.8 months (95% CI 3.7–8.1), median progression-free survival 2.8 months (95% CI 2.5–2.9). The disease control rate at weeks 12 and 24 was 47% and 21%, respectively. Sixteen patients had stable disease (47%), none experienced partial or complete response. Treatment-related AEs were observed in 35 patients (66%), including 19 grade 3–4 events (36%). One drug-related death due to pancytopenia was observed. Conclusions Ipilimumab has very limited clinical activity in patients with metastatic UM. Toxicity was manageable when treated as per protocol-specific guidelines. Trial Registration ClinicalTrials.gov NCT01355120 PMID:25761109

    Melanoma is one of the most aggressive cancers known with a high rate of mortality and increasing global incidence. So, the development of radiopharmaceuticals for either diagnostic or therapeutic purposes could make enormous contributions to melanoma patient health care. We have been studying melanoma tumours through several targeting mechanisms including melanin or specific receptor based radiopharmaceuticals Structure activity studies indicate that the substitution patterns on radioiodinated benzamides significantly influence the uptake mechanism from melanin to sigma-receptor binding. Furthermore, the position of the iodine as well as the presence of key functional groups and substituents has resulted in compounds with varying degrees of activity uptake and retention in tumours. From these results, a novel molecule 2-(2-(4-(4-iodo benzyl)piperazin-1-yl)-2-oxo-ethyl)isoindoline- 1,3-dione (M.E.L.037) was synthesized, labelled with iodine-123 and evaluated for application in melanoma tumour scintigraphy and radiotherapy. The tumour imaging potential of {sup 123}IM.E.L.037 was studied in vivo in C.57 B.L./ 6 J female mice bearing the B.16 F.0. murine melanoma tumour and in BALB/c nude mice bearing the A.375 human amelanotic melanoma tumour by biodistribution, competition studies and by SPECT imaging. {sup 123}I-M.E.L.037 exhibited high and rapid uptake in the B.16 F.0 melanoma tumour at 1 h (13 % I.D./g) increasing with time to reach 25 % I.D./g at 6 h. A significant uptake was also observed in the eyes (2% I.D., at 3-6 h p.i.) of black mice. No uptake was observed in the tumour or in the eyes of nude mice bearing the A.375 tumour. Due to high uptake and long retention in the tumour and rapid body clearance, standardized uptake values(S.U.V.) of {sup 123}I-M.E.L.037 were 30 and 60, at 24 and 48 h p.i.,respectively. SPECT imaging of mice bearing the B.16 melanoma indicated the radioactivity was predominately located in the tumour followed by the eyes, while no

    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.

    BACKGROUND: A predominance of melanomas on the left side of the body has recently been described. No associations between tumour laterality and gender, age or anatomical site have been identified. AIM: The aim of this study was to investigate the prevalence of left-sided melanomas in an Irish population and to examine potential associations with various patient and tumour characteristics. METHODS: A retrospective chart review of patients with cutaneous melanoma who were treated over a 10-year period was carried out. Lateral distribution of melanoma on either side of the body was compared using chi(2) analysis and evaluated by gender, age group, anatomic location, histologic subtype and Breslow depth. RESULTS: More melanomas occurred on the left side (57%, P = 0.015), and this finding was particularly significant in females. For both genders combined, there were no statistically significant differences in laterality by age group, anatomic location, type of melanoma and Breslow depth. There were significantly more superficial spreading melanomas on the left side in both men and women. CONCLUSIONS: This study demonstrates a predominance of left-sided melanomas in Irish patients. While a number of demographic and molecular associations have been proposed, further research is required to fully explain this phenomenon.

    Complementary and alternative medicine (CAM) is used widely among cancer patients. Beside the risk of interaction with cancer therapies, interactions with treatment for comorbidities are an underestimated problem. The aim of this study was to assess prevalence of interactions between CAM and drugs for comorbidities from a large CAM usage survey on melanoma patients and to classify herb-drug interactions with regard to their potential to harm. Consecutive melanoma outpatients of seven skin cancer centers were asked to complete a standardized CAM questionnaire including questions to their CAM use and their taken medication for comorbidities and cancer. Each combination of conventional drugs and complementary substances was evaluated for their potential of interaction. 1089 questionnaires were eligible for evaluation. From these, 61.6% of patients reported taking drugs regularly from which 34.4% used biological-based CAM methods. Risk evaluation for interaction was possible for 180 CAM users who listed the names or substances they took for comorbidities. From those patients, we found 37.2% at risk of interaction of their co-consumption of conventional and complementary drugs. Almost all patients using Chinese herbs were at risk (88.6%). With a high rate of CAM usage at risk of interactions between CAM drugs and drugs taken for comorbidities, implementation of a regular assessment of CAM usage and drugs for comorbidities is mandatory in cancer care.

    Full Text Available In advanced cancers, transforming growth factor-beta (TGFβ promotes tumor growth and metastases and suppresses host antitumor immunity. GC1008 is a human anti-TGFβ monoclonal antibody that neutralizes all isoforms of TGFβ. Here, the safety and activity of GC1008 was evaluated in patients with advanced malignant melanoma and renal cell carcinoma.In this multi-center phase I trial, cohorts of patients with previously treated malignant melanoma or renal cell carcinoma received intravenous GC1008 at 0.1, 0.3, 1, 3, 10, or 15 mg/kg on days 0, 28, 42, and 56. Patients achieving at least stable disease were eligible to receive Extended Treatment consisting of 4 doses of GC1008 every 2 weeks for up to 2 additional courses. Pharmacokinetic and exploratory biomarker assessments were performed.Twenty-nine patients, 28 with malignant melanoma and 1 with renal cell carcinoma, were enrolled and treated, 22 in the dose-escalation part and 7 in a safety cohort expansion. No dose-limiting toxicity was observed, and the maximum dose, 15 mg/kg, was determined to be safe. The development of reversible cutaneous keratoacanthomas/squamous-cell carcinomas (4 patients and hyperkeratosis was the major adverse event observed. One malignant melanoma patient achieved a partial response, and six had stable disease with a median progression-free survival of 24 weeks for these 7 patients (range, 16.4-44.4 weeks.GC1008 had no dose-limiting toxicity up to 15 mg/kg. In patients with advanced malignant melanoma and renal cell carcinoma, multiple doses of GC1008 demonstrated acceptable safety and preliminary evidence of antitumor activity, warranting further studies of single agent and combination treatments.Clinicaltrials.gov NCT00356460.

    Full Text Available Abstract Background The tumor associated antigen (TAA gp100 was one of the first identified and has been used in clinical trials to treat melanoma patients. However, the gp100 epitope peptide restricted to HLA-A*2402 has not been extensively examined clinically due to the ethnic variations. Since it is the most common HLA Class I allele in the Japanese population, we performed a phase I clinical trial of cancer vaccination using the HLA-A*2402 gp100 peptide to treat patients with metastatic melanoma. Methods The phase I clinical protocol to test a HLA-A*2402 gp100 peptide-based cancer vaccine was designed to evaluate safety as the primary endpoint and was approved by The University of Tokyo Institutional Review Board. Information related to the immunologic and antitumor responses were also collected as secondary endpoints. Patients that were HLA-A*2402 positive with stage IV melanoma were enrolled according to the criteria set by the protocol and immunized with a vaccine consisting of epitope peptide (VYFFLPDHL, gp100-in4 emulsified with incomplete Freund's adjuvant (IFA for the total of 4 times with two week intervals. Prior to each vaccination, peripheral blood mononuclear cells (PBMCs were separated from the blood and stored at -80°C. The stored PBMCs were thawed and examined for the frequency of the peptide specific T lymphocytes by IFN-γ- ELISPOT and MHC-Dextramer assays. Results No related adverse events greater than grade I were observed in the six patients enrolled in this study. No clinical responses were observed in the enrolled patients although vitiligo was observed after the vaccination in two patients. Promotion of peptide specific immune responses was observed in four patients with ELISPOT assay. Furthermore, a significant increase of CD8+ gp100-in4+ CTLs was observed in all patients using the MHC-Dextramer assay. Cytotoxic T lymphocytes (CTLs clones specific to gp100-in4 were successfully established from the PBMC of some

    Full Text Available The anorectum is a rare anatomic location for primary melanoma. Mucosal melanoma is a distinct biological and clinical entity from the more common cutaneous melanoma. It portrays worse prognosis than cutaneous melanoma, with distant metastases being the overwhelming cause of morbidity and mortality. Surgery is the treatment of choice, but significant controversy exists over the extent of surgical resection. We present an update on the state of the art of anorectal mucosal melanoma. To illustrate the multimodality approach to anorectal melanoma, we present a typical patient.

    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.

Unfortunately, the expression of ADAM15 in human melanoma tissue has not been determined so far. 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-γ and TGF-β 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.

    Testicular cancer affects men mostly in their reproductive age with a cure rate over 90% and fertility is one of the main concerns of survivors. To further elucidate the question of fertility after treatment for testicular cancer, we performed a survey in patients treated in our institution. We sent a questionnaire to patients treated for testicular cancer at our institute from 1976 to 2002 (n = 490) of whom 297 (60.6%) responded. We considered the patients to have conserved fertility if they had children after treatment without assisted reproductive technologies. Before treatment 119/297 (40.1%) of patients and after treatment 150/297 (50.5%) of patients tried to have children (p = 0.019). Of 119 patients who tried to have children before treatment for testicular cancer 98 (82.4%) succeeded and 74/150 (49.3%) were successful after treatment (p years. The post-treatment fatherhood in patients treated with surgery only (orchidectomy +/- retroperitoneal lymphnode dissection-RPLND) was 59%, in those with additional radiotherapy 68%, and chemotherapy 50% (p = 0.233). Fertility rate in patients where a non nerve sparing RPLND was performed was only 37%, 62% in patients with nerve sapring RPLND, and 77% in patients where RPLND was not performed (p Fertility rate after treatment for testicular cancer is reduced. From our data, the most important treatment modality that influences fertility is non nerve sparing RPLND that should be avoided whenever possible in order improve the quality of life our patients.

    Introduction: In spite of recently approved B-RAF inhibitors and immunomodulating antibodies, metastatic melanoma has poor prognosis and novel treatments are needed. Melanoma stem cells (MSC) have been implicated in the resistance of this tumor to chemotherapy. Recently we demonstrated in a Phase I clinical trial in patients with metastatic melanoma that radioimmunotherapy (RIT) with 188-Rhenium( 188 Re)-6D2 antibody to melanin was a safe and effective modality. Here we investigated the interaction of MSC with RIT as a possible mechanism for RIT efficacy. Methods: Mice bearing A2058 melanoma xenografts were treated with either 1.5 mCi 188 Re-6D2 antibody, saline, unlabeled 6D2 antibody or 188 Re-labeled non-specific IgM. Results: On Day 28 post-treatment the tumor size in the RIT group was 4-times less than in controls (P < 0.001). The tumors were analyzed by immunohistochemistry and FACS for two MSC markers — chemoresistance mediator ABCB5 and H3K4 demethylase JARID1B. There were no significant differences between RIT and control groups in percentage of ABCB5 or JARID1B-positive cells in the tumor population. Our results demonstrate that unlike chemotherapy, which kills tumor cells but leaves behind MSC leading to recurrence, RIT kills MSC at the same rate as the rest of tumor cells. Conclusions: These results have two main implications for melanoma treatment and possibly other cancers. First, the susceptibility of ABCB5 + and JARID1B + cells to RIT in melanoma might be indicative of their susceptibility to antibody-targeted radiation in other cancers where they are present as well. Second, specifically targeting cancer stem cells with radiolabeled antibodies to ABCB5 or JARID1B might help to completely eradicate cancer stem cells in various cancers

    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.

    Sun-exposure is one of the risk factors associated with the development of a cutaneous neoplasm. In melanoma, the Ras-Raf-MEK-ERK (MAPK) signaling pathway is constitutively activated through multiple mechanisms, including B-RAF mutation. It has been hypothesized that B-RAF mutations in melanocytic lesions arise from DNA damage induced by ultraviolet (UV) radiation. However, it is still discussed if B-RAF mutations are associated with melanoma patients exposed to the sun. Therefore, in the present study, the known B-RAFV600E mutation was analysed in melanoma samples from 30 indoor and 38 outdoor workers. B-RAFV600E mutation was detected in 52 and 73% of outdoor workers and indoor workers, respectively. Of note, this mutation was identified in 12 of 14 (85%) melanoma of the trunk diagnosed in indoor workers and in 9 of 19 (47%) samples from outdoor workers (p=0.03). By analyzing melanomas of other body sites, no statistical difference in the frequency of B-RAFV600E mutation was identified between the groups of workers. It appears that the mutation detected among indoor workers may be associated with a recreational or intermittent exposure to the sun, as usually the trunk is a sun-protected body site. Overall, these data indicate that the B-RAFV600E mutation detected in melanoma is not associated with a chronic exposure to the sun. Mutations detected in other genes may also contribute to melanoma development in the subset of patients exposed to UV radiation. PMID:24424406

    To evaluate the influence of {sup 18}F-FDG-PET/CT on clinical decision making and outcome in advanced melanoma patients planned for radical metastasectomy. A cohort of 333 patients with mainly stage III/IV melanoma having a PET/CT for clinical reasons was prospectively enrolled in our oncologic PET/CT registry between 2013 and 2015. Referring physicians completed questionnaires regarding their intended management for each patient before and after PET/CT. Management changes after PET/CT were classified as major and minor changes. A subgroup of 107 patients (stage I, N = 5; stage II, N = 3; stage III, N = 42; stage IV, N = 57) was planned for complete metastasectomy initially, based on conventional imaging. Management changes and outcome were evaluated by linkage with the information obtained from patients' medical records. In 28 of 107 patients (26%), the surgical treatment plan remained unchanged after PET/CT. In 24 patients (22%), minor changes were performed, such as enlargement or reduction of the surgical field. In 55 patients (51%, 95% CI 42%-61%) major changes of the intended treatment plan occurred; of those, 20 patients (19%) were classified to be tumor-free with PET/CT, 32 patients (30%) were found to have multiple previously unrecognized metastases and had to be treated by systemic therapy, three patients (3%) had to be changed to palliative radiotherapy or isolated extremity perfusion. The 1-year and 2-year overall survival (OS) in patients with complete metastasectomy (N = 52) was 90% and 79%, respectively. Systemically treated patients (N = 32) resulted in 1-year OS of 72% and 2-year OS of 61%. Eleven of 32 patients (34%) with systemic therapy experienced a complete response. Until December 2016, all 20 patients classified as tumor-free by PET/CT were alive. The study confirms the high impact of PET/CT on clinical management in patients with advanced melanoma planned for radical metastasectomy. PET/CT resulted in frequent management changes

    Full Text Available Objective: to describe the results of the joint monitoring and diversified treatment of oncologists and dermatologists those patient with multiple recurrent melanoma who received over a long period a targeted anti-cancer therapy, which was complicated by side-effect as widespread acneform rush, resistant to traditional treatment. Patient A., born in 1988, was followed up and got a treatment more than 2 years in oncology out-patient clinic diagnosed with “Melanoma of the front surface of the left leg T2bN0M0 IIA”. Subsequently, the patient was verified metastasis in the inginal lymph nodes, in the soft tissues of the hips, to liver. Acute adverse reaction has developed in a short time after getting the anti-tumor target therapy as generalized acneform rush and itching of the skin. Skin symptoms accompanied by pronounced psychological and emotional stress, therefore, dermatologists have been invited to provide additional medical assistance to this patient. Due to the fact that subsequent traditional anti-acne algorithms of topical and oral treatment was not such effective, there was made a decision to use an alternative supporting external therapy, which did not have similar examples of usage previously. Results. External application of tacrolimus ointment in combination with other drugs and then as a mono-therapy, allows us in a rather short period achieve a stable and pronounced regression of skin pathological lesions, to return to the previously cancelled initial drug dose of the anti-tumor target therapy, to change significantly components of the patient’s quality of life. Conclusion. The search for additional and alternative treatment approaches for similar patients, as in our case, remains relevant for specialists and patients themselves. This case is an example of alternative approach to the tacrolimus topical application in patient with drug-mediated acneform rush.

    Concurrent biochemotherapy results in high response rates but also significant toxicity in patients with metastatic melanoma. We attempted to improve its efficacy and decrease its toxicity by using decrescendo dosing of interleukin-2 (IL-2), posttreatment granulocyte colony-stimulating factor (G-CSF), and low-dose tamoxifen. Forty-five patients with poor prognosis metastatic melanoma were treated at a community hospital inpatient oncology unit affiliated with the John Wayne Cancer Institute (Santa Monica, CA) between July 1995 and September 1997. A 5-day modified concurrent biochemotherapy regimen of dacarbazine, vinblastine, cisplatin, decrescendo IL-2, interferon alfa-2b, and tamoxifen was repeated at 21-day intervals. G-CSF was administered beginning on day 6 for 7 to 10 days. The overall response rate was 57% (95% confidence interval, 42% to 72%), the complete response rate was 23%, and the partial response rate was 34%. Complete remissions were achieved in an additional 11% of patients by surgical resection of residual disease after biochemotherapy. The median time to progression was 6.3 months and the median duration of survival was 11.4 months. At a maximum follow-up of 36 months (range, 10 to 36 months), 32% of patients are alive and 14% remain free of disease. Decrescendo IL-2 dosing and administration of G-CSF seemed to reduce toxicity, length of hospital stay, and readmission rates. No patient required intensive care unit monitoring, and there were no treatment-related deaths. The data from this study indicate that the modified concurrent biochemotherapy regimen reduces the toxicity of concurrent biochemotherapy with no apparent decrease in response rate in patients with poor prognosis metastatic melanoma.

    We report 3 cases of durable complete response (CR) in patients with BRAF-mutated metastatic melanoma who were initially treated unsuccessfully with sequential immunotherapies (high dose interleukin 2 followed by ipilimumab with or without concurrent radiation therapy). After progression during or post immunotherapy, these patients were given BRAF inhibitor therapy and developed rapid CRs. Based on the concomitant presence of autoimmune manifestations (including vitiligo and hypophysitis), we postulated that there was a synergistic effect between the prior immune therapy and the BRAF targeting agents. Accordingly, the inhibitors were gradually weaned off beginning at 3 months and were stopped completely at 9-12 months. The three patients remain well and in CR off of all therapy at up to 15 months radiographic follow-up. The institution of the BRAF therapy was associated with development of severe rheumatoid-like arthritis in 2 patients which persisted for months after discontinuation of therapy, suggesting it was not merely a known toxicity of BRAF inhibitors (arthralgias). On immunologic analysis, these patients had high levels of non-T-regulatory, CD4 positive effector phenotype T-cells, which persisted after completion of therapy. Of note, we had previously reported a similar phenomenon in patients with metastatic melanoma who failed high dose interleukin-2 and were then placed on a finite course of temozolomide with rapid complete responses that have remained durable for many years after discontinuation of temozolomide. We postulate that a finite course of cytotoxic or targeted therapy specific for melanoma given after apparent failure of prior immunotherapy can result in complete and durable remissions that may persist long after the specific cytotoxic or targeted agents have been discontinued suggesting the existence of sequence specific synergism between immunotherapy and these agents. Here, we discuss these cases in the context of the literature on

    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.

    Disseminated metastatic disease, including brain metastases, is commonly encountered in malignant melanoma. The classical treatment approach for melanoma brain metastases has been neurosurgical resection followed by whole brain radiotherapy. Traditionally, if lesions were either too numerous or surgical intervention would cause substantial neurologic deficits, patients were either treated with whole brain radiotherapy or referred to hospice and supportive care. Chemotherapy has not proven effective in treating brain metastases. Improvements in surgery, radiosurgery, and new drug discoveries have provided a wider range of treatment options. Additionally, recently discovered mutations in the melanoma genome have led to the development of "targeted therapy."These vastly improved options are resulting in novel treatment paradigms for approaching melanoma brain metastases in patients with and without systemic metastatic disease. It is therefore likely that improved survival can currently be achieved in at least a subset of melanoma patients with brain metastases.

    A patient assembly adapter system for ocular melanoma patient simulation was developed and its performance evaluated. The aim for the construction of the apparatus was to simulate the patients in supine position using a commercial x-ray simulator. The apparatus consists of a base plate, head immobilization holder, patient assembly system that includes fixation light and collimator system. The reproducibility of the repeated fixation was initially tested with a head phantom. Simulation and verification films were studied for seven consecutive patients treated with proton beam therapy. Patient's simulation was performed in a supine position using a dental fixation bite block and a thermoplastic head mask immobilization device with a patient adapter system. Two orthogonal x rays were used to obtain the x, y, and z coordinates of sutured tantalum rings for treatment planning with the EYEPLAN software. The verification films were obtained in treatment position with the fixation light along the central axis of the eye. The results indicate good agreement within 0.5 mm deviations. The results of this investigation showed that the same planning accuracy could be achieved by performing simulation using the adapter described above with a patient in the supine position as that obtained by performing simulation with the patient in the seated, treatment position. The adapter can also be attached to the head of the chair for simulating in the seated position using a fixed x-ray unit. This has three advantages: (1) this will save radiation therapists time; (2) it eliminates the need for arranging access to the treatment room, thus avoiding potential conflicts in treatment room usage; and (3) it allows the use of a commercial simulator

    Survivin is a microtubule-associated protein believed to be involved in preserving cell viability and regulating tumor cell mitosis, and it is overexpressed in many primary tumor types, including melanoma. YM155 is a first-in-class survivin suppressant. The purpose of this Phase 2 study was to evaluate the 6-month progression-free survival (PFS) rate in patients with unresectable Stage III or IV melanoma receiving a combination of YM155 plus docetaxel. The study had two parts: Part 1 established the dose of docetaxel that was tolerable in combination with YM155, and Part 2 evaluated the tolerable docetaxel dose (75 mg/m 2 ) in combination with YM155 (5 mg/m 2 per day continuous infusion over 168 h every 3 weeks). The primary endpoint was 6-month PFS rate. Secondary endpoints were objective response rate (ORR), 1-year overall survival (OS) rate, time from first response to progression, clinical benefit rate (CBR), and safety. Sixty-four patients with metastatic melanoma were treated with docetaxel and YM155. Eight patients received an initial docetaxel dose of 100 mg/m 2 and 56 patients received 75 mg/m 2 of docetaxel. Six-month PFS rate per Independent Review Committee (IRC) was 34.8% (n = 64; 95% CI, 21.3–48.6%), and per Investigator was 31.3% (n = 64; 95% CI, 19.5–43.9%). The best ORR (complete response [CR] + partial response [PR]) per IRC was 12.5% (8/64). The stable disease (SD) rate was 51.6% (33/64), leading to a CBR (CR + PR + SD) of 64.1% (41/64). Estimated probability of 1-year survival was 56.3%. YM155 is a novel agent showing modest activity when combined with docetaxel for treating patients with melanoma. YM155 was generally well tolerated, but the predetermined primary efficacy endpoint (i.e., 6-month PFS rate ≥20%) was not achieved

Side effects included mild nausea and vomiting and moderate degree of myelosuppression. AMSA has poor activity against previously treated metastatic melanoma.

  16. Canine oral melanoma.

    Science.gov (United States)

    Bergman, Philip J

    2007-05-01

    Melanoma is the most common oral malignancy in the dog. Oral and/or mucosal melanoma has been routinely considered an extremely malignant tumor with a high degree of local invasiveness and high metastatic propensity. Primary tumor size has been found to be extremely prognostic. The World Health Organization staging scheme for dogs with oral melanoma is based on size, with stage I = or = 4cm tumor and/or lymph node metastasis, and stage IV = distant metastasis. Median survival times for dogs with oral melanoma treated with surgery are approximately 17 to 18, 5 to 6, and 3 months with stage I, II, and III disease, respectively. Significant negative prognostic factors include stage, size, evidence of metastasis, and a variety of histologic criteria. Standardized treatments such as surgery, coarse-fractionation radiation therapy, and chemotherapy have afforded minimal to modest stage-dependent clinical benefits and death is usually due to systemic metastasis. Numerous immunotherapeutic strategies have been employed to date with limited clinical efficacy; however, the use of xenogeneic DNA vaccines may represent a leap forward in clinical efficacy. Oral melanoma is a spontaneous syngeneic cancer occurring in outbred, immunocompetent dogs and appears to be a more clinically faithful therapeutic model for human melanoma; further use of canine melanoma as a therapeutic model for human melanoma is strongly encouraged. In addition, the development of an expanded but clinically relevant staging system incorporating the aforementioned prognostic factors is also strongly encouraged.

    S100B protein detected in the serum of patients with cutaneous melanoma has been long reported as a prognostic biomarker. However, no consensus exists on its implementation in the routine clinical setting. This study aimed to comprehensively and quantitatively summarize the evidence on the suitability of serum S100B to predict patients' survival. Twenty-two series enrolling 3393 patients with TNM stage I to IV cutaneous melanoma were reviewed. Standard meta-analysis methods were applied to evaluate the overall relationship between S100B serum levels and patients' survival (meta-risk). Serum S100B positivity was associated with significantly poorer survival (hazard ratio [HR] = 2.23, 95% CI: 1.92-2.58, p < 0.0001). Between-study heterogeneity was significant, which appeared to be related mainly to dissemination bias and the inclusion of patients with stage IV disease. Considering stage I to III melanoma (n = 1594), the meta-risk remained highly significant (HR = 2.28, 95% CI: 1.8-2.89; p < 0.0001) and studies' estimates were homogeneous. Subgroup analysis of series reporting multivariate survival analysis supported S100B as a prognostic factor independent of the TNM staging system. Our findings suggest that serum S100B detection has a clinically valuable independent prognostic value in patients with melanoma, with particular regard to stage I-III disease. Further investigation focusing on this subset of patients is justified and warranted before S100B can be implemented in the routine clinical management of melanoma. (c) 2008 Wiley-Liss, Inc.

    Purpose Until recently, limited options existed for patients with advanced melanoma who experienced disease progression while receiving treatment with ipilimumab. Here, we report the coprimary overall survival (OS) end point of CheckMate 037, which has previously shown that nivolumab resulted in more patients achieving an objective response compared with chemotherapy regimens in ipilimumab-refractory patients with advanced melanoma. Patients and Methods Patients were stratified by programmed death-ligand 1 expression, BRAF status, and best prior cytotoxic T-lymphocyte antigen-4 therapy response, then randomly assigned 2:1 to nivolumab 3 mg/kg intravenously every 2 weeks or investigator's choice chemotherapy (ICC; dacarbazine 1,000 mg/m 2 every 3 weeks or carboplatin area under the curve 6 plus paclitaxel 175 mg/m 2 every 3 weeks). Patients were treated until they experienced progression or unacceptable toxicity, with follow-up of approximately 2 years. Results Two hundred seventy-two patients were randomly assigned to nivolumab (99% treated) and 133 to ICC (77% treated). More nivolumab-treated patients had brain metastases (20% v 14%) and increased lactate dehydrogenase levels (52% v 38%) at baseline; 41% of patients treated with ICC versus 11% of patients treated with nivolumab received anti-programmed death 1 agents after randomly assigned therapy. Median OS was 16 months for nivolumab versus 14 months for ICC (hazard ratio, 0.95; 95.54% CI, 0.73 to 1.24); median progression-free survival was 3.1 months versus 3.7 months, respectively (hazard ratio, 1.0; 95.1% CI, 0.78 to 1.436). Overall response rate (27% v 10%) and median duration of response (32 months v 13 months) were notably higher for nivolumab versus ICC. Fewer grade 3 and 4 treatment-related adverse events were observed in patients on nivolumab (14% v 34%). Conclusion Nivolumab demonstrated higher, more durable responses but no difference in survival compared with ICC. OS should be interpreted with

    Anxiety is a common yet frequently overlooked psychiatric symptom in patients with ESRD treated with hemodialysis (HD). Anxiety is characterized by disruptive feelings of uncertainty, dread, and fearfulness. A variety of common medical complaints may be manifestations of an anxiety disorder, including palpitations, tremors, indigestion, numbness/tingling, nervousness, shortness of breath, diaphoresis, and fear. It is essential for the clinician to rule out specific medical conditions, including cardiovascular, pulmonary, and neurologic diseases, before ascribing these symptoms to an anxiety disorder. In addition, there is considerable overlap between the symptoms of anxiety and those of depression and uremia. This psychiatric condition has a significant adverse impact on patients' perception of quality of life. Little is known regarding the prevalence and impact of anxiety disorders in patients with ESRD treated with HD; however, many of the seemingly irrational behaviors of patients, or behaviors which place them in conflict with staff and physicians, such as behavioral noncompliance, may be the expression of an underlying anxiety disorder. In this review, we present three clinical vignettes, highlighting the impact of anxiety disorders in patients with ESRD treated with HD. Copyright © 2016 by the American Society of Nephrology.

    Full Text Available Introduction: Primary dermal melanoma (PDM is a recently described clinical entity accounting for less than 1% of all melanomas. Histologically, it is located in the dermis or subcutaneous tissue, and it shows no connections with the overlying epidermis. The differential diagnosis is principally made along with that of metastatic cutaneous melanoma. Case Report: A 72-year-old Caucasian woman with a history of multiple cancers (metachronous bilateral breast cancer, meningioma, clear cell renal cell carcinoma, uterine fibromatosis and intestinal adenomatous polyposis, came to our attention with a nodular lesion on her back. After removal of the lesion, the histology report indicated malignant PDM or metastatic malignant melanoma. The clinical and instrumental evaluation of the patient did not reveal any other primary tumour, suggesting the primitive nature of the lesion. The absence of an epithelial component argued for a histological diagnosis of PDM. Subsequently, the patient underwent a wide surgical excision with sentinel node biopsy, which was positive for metastatic melanoma. Finally, the mutational status was studied in the main genes that regulate proliferation, apoptosis and cellular senescence. No pathogenetic mutations in CDKN2A, BRAF, NRAS, KRAS, cKIT, TP53 and PTEN genes were observed. This suggests that alternative pathways and low-frequency alterations may be involved. Conclusions: The differential diagnosis between PDM and isolated metastatic melanoma depends on the negativity of imaging studies and clinical findings for other primary lesions. This distinction is important because 5-year survival rates in such cases are higher than in metastatic cases (80-100 vs. 5-20%, respectively.

    The aim of this study was to compare early dynamic imaging combined with delayed static imaging and single photon emission computed tomography (SPECT)/CT with delayed, planar, static imaging alone for sentinel node (SN) identification in melanoma patients. Three hundred and seven consecutive melanoma patients referred for SN biopsy (SNB) were examined using combined imaging. Secondary interpretation of only the delayed static images was subsequently performed. In 220 patients (72%), complete surgical and pathological information relating to the SNB was available. The number of SNs identified and number of patients with positive SNs were compared between the two interpretations of the imaging studies and, when available, related to pathology data. A slightly higher number of SNs (mean 0.12/patient) was identified when interpreting only delayed static images compared to combined imaging. In a direct patient-to-patient comparison, the number of SN(s) identified on the combined vs static images only showed moderate agreement (kappa value 0.56). In 38 patients (17%), positive SNs were identified by the combined procedure compared to 35 (16%) by static imaging only. Thus by static imaging only, tumour-positive SNs were not identified in 3 of 38 patients (8%). For SN identification in melanoma patients, dynamic imaging combined with delayed static imaging and SPECT/CT is superior to delayed static imaging only because the latter is more likely to fail to identify SNs containing metastases.

    Full Text Available Abstract 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.

    Next-generation sequencing (NGS) has reached the molecular diagnostic laboratories. Although the NGS technology aims to improve the effectiveness of therapies by selecting the most promising therapy, concerns are that NGS testing is expensive and that the ‘benefits’ are not yet in relation to these costs. In this study, we give an estimation of the costs and an institutional and national budget impact of various types of NGS tests in non-small-cell lung cancer (NSCLC) and melanoma patients within The Netherlands. First, an activity-based costing (ABC) analysis has been conducted on the costs of two examples of NGS panels (small- and medium-targeted gene panel (TGP)) based on data of The Netherlands Cancer Institute (NKI). Second, we performed a budget impact analysis (BIA) to estimate the current (2015) and future (2020) budget impact of NGS on molecular diagnostics for NSCLC and melanoma patients in The Netherlands. Literature, expert opinions, and a data set of patients within the NKI (n = 172) have been included in the BIA. Based on our analysis, we expect that the NGS test cost concerns will be limited. In the current situation, NGS can indeed result in higher diagnostic test costs, which is mainly related to required additional tests besides the small TGP. However, in the future, we expect that the use of whole-genome sequencing (WGS) will increase, for which it is expected that additional tests can be (partly) avoided. Although the current clinical benefits are expected to be limited, the research potentials of NGS are already an important advantage. PMID:27899957

    Osteoporosis is a chronic disease, carrying an elevated risk of fractures, morbidity, and death. Long-term treatment may be required, but the long-term risks with osteoporosis drugs remain incompletely understood. The competing risk of death may be a barrier to treating the oldest, yet this may...... not be rational if the risk of death is reduced by treatment. It is difficult to devise goal-directed long-term strategies for managing osteoporosis without firm information about residual life expectancy in treated patients. We conducted an observational study in Danish national registries tracking prescriptions...... for osteoporosis drugs, comorbid conditions, and deaths. We included 58,637 patients and 225,084 age- and sex-matched control subjects. Information on deaths until the end of 2013 was retrieved, providing a follow-up period of 10 to 17 years. In men younger than 80 years and women younger than 60 years...

    The prognostic impact of BRAF-V600 tumor mutations in stage I/II melanoma patients has not yet been analyzed in detail. We investigated primary tumors of 437 patients diagnosed between 1989 and 2006 by Sanger sequencing. Mutations were detected in 38.7% of patients and were associated with age, histological subtype as well as mitotic rate. The mutational rate was 36.7% in patients with disease-free course and 51.7% in those with subsequent distant metastasis (p = 0.031). No difference in overall survival (p = 0.119) but a trend for worse distant-metastasis-free survival (p = 0.061) was observed in BRAF mutant compared to BRAF wild-type patients. Independent prognostic factors for overall survival were tumor thickness, mitotic rate and ulceration. An interesting significant prognostic impact was observed in patients with tumor thickness of 1 mm or less, with the mutation present in 6 of 7 patients dying from melanoma. In conclusion, no significant survival differences were found according to BRAF-V600 tumor mutations in patients with primary melanoma but an increasing impact of the mutational status was observed in the subgroup of patients with tumor thickness of 1 mm or less. A potential role of the mutational status as a prognostic factor especially in this subgroup needs to be investigated in larger studies. PMID:24475086

    Currently interferon alfa-2b (IFNα-2b) is an approved adjuvant drug for high-risk melanoma patients that leads to an improvement in disease-free survival (DFS). However, it is unclear whether it also impacts overall survival. Widespread use of adjuvant high-dose IFNα has been tempered by its significant toxicity and its limited efficacy. Current therapeutic strategies like immune checkpoint blockade or targeted therapy may also be useful in the adjuvant setting. Therefore, it is important to weigh the trade-offs between possible side effects and therapeutic benefit.We assessed patient utilities for health states associated with IFN therapy. Utilities are measures of preference for a specific health state on a scale of 0 (death) to 1 (perfect health).Utilities were determined for health states associated with adjuvant IFN among 130 German low-risk melanoma patients using the standard gamble technique. Four IFNα-2b toxicity scenarios and the following 3 posttreatment outcomes were assessed: disease-free health and melanoma recurrence (with or without previous use of IFNα-2b) resulting in cancer death. Patients were asked to trade-off the improvement in 5-year DFS and the IFN-related side effects.Utilities for melanoma recurrence (mean 0.60) were significantly lower than for all IFNα-2b toxicity scenarios (mean 0.81-0.90). Patients were willing to tolerate mild-to-moderate and severe toxicity for a 50% and 75% chance of 5-year DFS, respectively. Both utilities and threshold benefits were mostly independent from patient characteristics like gender, income, and social situation. Significant impact was only observed by age and previous personal experience with cancer.On average, German patients were willing to trade even severe IFNα-2b toxicity for reducing the rate of melanoma recurrence. This result points out the importance of a relapse-free survival for melanoma patients. The utilities measured in our study can be applied to decision-making processes in

    Full Text Available Uveal melanoma is the most common primary malignant tumor of the eye in adults, predominantly found in Caucasians. Local tumor control of uveal melanoma is excellent, yet this malignancy is associated with relatively high mortality secondary to metastasis. Various clinical, histopathological, cytogenetic features and gene expression features help in estimating the prognosis of uveal melanoma. The clinical features associated with poor prognosis in patients with uveal melanoma include older age at presentation, male gender, larger tumor basal diameter and thickness, ciliary body location, diffuse tumor configuration, association with ocular/oculodermal melanocytosis, extraocular tumor extension, and advanced tumor staging by American Joint Committee on Cancer classification. Histopathological features suggestive of poor prognosis include epithelioid cell type, high mitotic activity, higher values of mean diameter of ten largest nucleoli, higher microvascular density, extravascular matrix patterns, tumor-infiltrating lymphocytes, tumor-infiltrating macrophages, higher expression of insulin-like growth factor-1 receptor, and higher expression of human leukocyte antigen Class I and II. Monosomy 3, 1p loss, 6q loss, and 8q and those classified as Class II by gene expression are predictive of poor prognosis of uveal melanoma. In this review, we discuss the prognostic factors of uveal melanoma. A database search was performed on PubMed, using the terms "uvea," "iris," "ciliary body," "choroid," "melanoma," "uveal melanoma" and "prognosis," "metastasis," "genetic testing," "gene expression profiling." Relevant English language articles were extracted, reviewed, and referenced appropriately.

    2011-01-01

    Full Text Available Altered natural killer (NK cell function is a component of the global immune dysregulation that occurs in advanced malignancies. Another condition associated with altered NK homeostasis is normal pregnancy, where robust infiltration with CD16− CD9+ NK cells can be identified in decidual tissues, along with a concomitant expansion of CD16− NK cells in the maternal peripheral blood. In metastatic melanoma, we identified a similar expansion of peripheral blood CD16− NK cells (median 7.4% in 41 patients with melanoma compared with 3.0% in 29 controls, P<.001. A subset of NK cells in melanoma patients also expresses CD9, which is characteristically expressed only on NK cells within the female reproductive tract. Expansion of CD16− NK cells was associated with elevated plasma transforming growth factor-beta (TGF-β levels (median 20 ng/ml, Spearman's ρ=0.81,P=.015. These findings suggest the possibility of exploring anti-TGF-β therapy to restore NK function in melanoma.

    Full Text Available Although malignant melanoma (MM and both basal cell carcinoma (BCC and actinic keratosis (AK are sun-induced lesions, the coexistence of these entities at the same anatomical site (collision tumour is exceedingly rare. We report the case of a 54-year-old woman with a known history of xeroderma pigmentosum variant (XPV who presented with 2 separate skin lesions over the middle and upper right forearm, respectively. The clinical impression was that of BCCs or squamous cell lesions. On histological examination, both specimens showed features of melanoma in situ (MIS. In the first lesion, MIS merged with and colonised a superficial and focally invasive BCC. In the second lesion, MIS merged with an AK. No separate invasive nests of malignant melanoma were seen in either specimen. The atypical melanocytes were highlighted by Melan-A and HMB-45 immunostaining, whereas the epithelial cells in both the BCC and AK stained with the pancytokeratin MNF-116. The patient had a previous history of multiple MMs and non-melanomatous skin cancers and finally developed widespread metastatic malignant melanoma, which proved fatal. The rare and interesting phenomenon of collision tumours may pose diagnostic difficulties. To our knowledge, this is the first reported simultaneous presentation of cytologically malignant collision tumours in a patient with XPV.

    We sought to define cellular immune mechanisms of synergy between tumor-antigen–targeted monoclonal antibodies and chemotherapy. Established B16 melanoma in mice was treated with cytotoxic doses of cyclophosphamide in combination with an antibody targeting tyrosinase-related protein 1 (αTRP1), a native melanoma differentiation antigen. We find that Fcγ receptors are required for efficacy, showing that antitumor activity of combination therapy is immune mediated. Rag1−/− mice deficient in adaptive immunity are able to clear tumors, and thus innate immunity is sufficient for efficacy. Furthermore, previously treated wild-type mice are not significantly protected against tumor reinduction, as compared with mice inoculated with irradiated B16 alone, consistent with a primarily innate immune mechanism of action of chemo-immunotherapy. In contrast, mice deficient in both classical natural killer (NK) lymphocytes and nonclassical innate lymphocytes (ILC) due to deletion of the IL2 receptor common gamma chain IL2γc−/−) are refractory to chemo-immunotherapy. Classical NK lymphocytes are not critical for treatment, as depletion of NK1.1+ cells does not impair antitumor effect. Depletion of CD90+NK1.1− lymphocytes, however, both diminishes therapeutic benefit and decreases accumulation of macrophages within the tumor. Tumor clearance during combination chemo-immunotherapy with monoclonal antibodies against native antigen is mediated by the innate immune system. We highlight a novel potential role for CD90+NK1.1− ILCs in chemo-immunotherapy. PMID:25600438

    Metastases to the larynx are rare. The current article presents the case of a 75-year-old patient with a history of shortness of breath due to a supraglottic exophytic lesion that was identified as a metastasis of a cutaneous melanoma treated 2.5 years previously. As a result of our medline analysis we found approximately 30 cases of metastatic melanoma to the larynx published to date. Primary tumors are always cutaneous in origin and spread over the whole integument of trunk and extremities. The time interval between diagnosis of the primary and the laryngeal metastasis is often several years. In most reports a supraglottic exophytic, red coloured lesion is described. Diagnosis can only be proven by histological examination. Laryngeal metastasis is usually an indication of tumor dissemination and always has a fatal prognosis.

    2006-12-01

    The melanocyte differentiation Ag RAB38/NY-MEL-1 was identified by serological expression cloning (SEREX) and is expressed in the vast majority of melanoma lesions. The immunogenicity of RAB38/NY-MEL-1 has been corroborated previously by the frequent occurrence of specific Ab responses in melanoma patients. To elucidate potential CD8 T cell responses, we applied in vitro sensitization with overlapping peptides spanning the RAB38/NY-MEL-1 protein sequence and the reverse immunology approach. The identified peptide RAB38/NY-MEL-1(50-58) exhibited a marked response in ELISPOT assays after in vitro sensitization of CD8 T cells from HLA-A *0201(+) melanoma patients. In vitro digestion assays using purified proteasomes provided evidence of natural processing of RAB38/NY-MEL-1(50-58) peptide. Accordingly, monoclonal RAB38/NY-MEL-1(50-58)-specific T cell populations were capable of specifically recognizing HLA-A2(+) melanoma cell lines expressing RAB38/NY-MEL-1. Applying fluorescent HLA-A2/RAB38/NY-MEL-1(50-58) multimeric constructs, we were able to document a spontaneously developed memory/effector CD8 T cell response against this peptide in a melanoma patient. To elucidate the Ag-processing pathway, we demonstrate that RAB38/NY-MEL-1(50-58) is produced efficiently by the standard proteasome and the immunoproteasome. In addition to the identification of a RAB38/NY-MEL-1-derived immunogenic CD8 T cell epitope, this study is instrumental for both the onset and monitoring of future RAB38/NY-MEL-1-based vaccination trials.

    A prospective comparison of chest radiography, conventional tomography, and computed tomography (CT) in the detection or confirmation of solitary pulmonary nodules was made in 42 patients with high propensity for pulmonary metastases due to advanced local (Clark level IV or V) or regional malignant melanoma. Unequivocal nodules were revealed by chest radiography in 11 patients, conventional tomograhy in 16, and computed tomography in 20 patients. Both plain films and tomography in three of these 20 were normal, but follow-up verified pulmonary metastases. Computed tomography detected more pulmonary nodules than conventional tomography in 11 patients in addition to identifying lesions in extrapulmonary sites. Therefore, chest CT is recommended before institution of immunotherapy or surgical removal of a solitary pulmonary melanoma metastasis. Once chemotherapy had been instituted for bulky regional or cutaneous involvement, however, the findings of either conventional or computed tomography were comparable in this study

    A significant proportion of patients with American Joint Committee on Cancer (AJCC)-defined early-stage cutaneous melanoma have disease recurrence and die. A 31-gene expression profile (GEP) that accurately assesses metastatic risk associated with primary cutaneous melanomas has been described. We sought to compare accuracy of the GEP in combination with risk determined using the web-based AJCC Individualized Melanoma Patient Outcome Prediction Tool. GEP results from 205 stage I/II cutaneous melanomas with sufficient clinical data for prognostication using the AJCC tool were classified as low (class 1) or high (class 2) risk. Two 5-year overall survival cutoffs (AJCC 79% and 68%), reflecting survival for patients with stage IIA or IIB disease, respectively, were assigned for binary AJCC risk. Cox univariate analysis revealed significant risk classification of distant metastasis-free and overall survival (hazard ratio range 3.2-9.4, P risk by GEP but low risk by AJCC. Specimens reflect tertiary care center referrals; more effective therapies have been approved for clinical use after accrual. The GEP provides valuable prognostic information and improves identification of high-risk melanomas when used together with the AJCC online prediction tool.

    Despite the presence of several studies in literature, the real connection between vitamin D serological levels, vitamin D receptor and melanoma remains unclear, probably because of the complex correlation between vitamin D and melanoma. Indeed, UV radiations are not reported as the main risk factor for melanoma in non-sun-exposed, while systemic immunosuppression, anatomical and physiological features may contribute to malignancy. Therefore, the correlation between melanoma cells in sun- exposed areas and vitamin D, as well as vitamin D receptor could be different from the one in melanoma of sun-shielded sites. These differences may also explain the controversial results reported in the literature regarding the correlation between melanoma and vitamin D, as well as the different outcomes in melanoma patients treated with vitamin D as adjuvant therapy. The aim of this review is to highlight the most recent findings about vitamin D and melanoma, focusing on the anatomic site of the primary tumor as well as on the possible therapeutic uses of vitamin D in melanoma patients.

    Melanoma is the most serious skin cancer, and consistent use of sun protection is recommended to reduce risk. Yet sun protection use is generally inconsistent. Understanding the decisional factors driving sun protection choices could aid in intervention development to promote sun protection maintenance. In 59 first-degree relatives of melanoma patients, an interactive voice response system (IVRS) on participants' cell phones was used to assess twice daily (morning, afternoon) real-time sun protection usage (sunscreen, shade, hats, protective clothing) and decision factors (weather, type of activity, convenience, social support) over a 14-day summer interval where morning and afternoon outdoor exposures were anticipated. Generalized estimating equations and hierarchical linear models were used to examine the effect of demographics and decisional factors on sun protection choices over time. Sun protection use was inconsistent (e.g., 61% used sunscreen inconsistently). Most strategies were used independently, with the exception of moderate overlap of sunscreen and hat usage. Decision factors were highly relevant for sun protection. For instance, sunscreen use was related to the perception of having adequate time to apply it, whereas shade and hat usage were each related to convenience. Few findings emerged by gender, age, time of day, or year. Significant within-subject variation remained, however. The findings support continued examination of decision factors in understanding sun protection consistency in real time. Interventions where cues to action and environmental supports work together in varied settings can be developed to improve sun protection maintenance in populations at risk for this common disease.

    Full Text Available Melanomas are malignant neoplasms that originate from melanocytes. The most common are on the skin and mucous membranes. Choroidal melanomas are quite different from cutaneous melanomas with regard to presentation, metastases, and treatment. We report two cases of metastatic gastric malignant melanoma of the eye and skin, with reference to the literature. The first patient was a woman aged 23 years, who underwent gastrectomy 22 months after enucleation of the eye due to malignant choroid melanoma. The second patient was a man, 72 years old, who underwent surgery 28 months before because of malignant melanoma of the skin of the forehead. Paraffin sections, 4 μm thick were stained using a classic method, as well as immunohistochemical DAKO APAAP method, using a specific S - 100 antibody and Melan A antibodies. The stomach is considered a rare place for the development of metastases. Metastases in the stomach are often limited to the submucosal as well as the serousmuscular layer, as noted in one of our patients. Metastatic melanoma of the gastrointestinal tract should be suspected in any patient with a history of malignant melanoma and new gastrointestinal symptoms. Because of the similarity between certain common histopathological types of malignant melanoma, primarily achromatic, and types of primary cancers of the stomach, the following immunohistochemical studies are needed: Melan A and S - 100 protein ( markers of malignant melanoma , as well as mucins: MUC5AC, MUC2 and CDX2 ( markers of different types of primary gastric carcinoma.

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.

    Recently published studies show that the prevalence of polyneuropathy (PNP) is higher in patients with Parkinson's disease (PD) than in age-matched controls. Its pathogenesis, however is a matter of controversy. The major hypothesis is the toxicity of high concentrations of homocysteine (Hcy) possibly related to levodopa (LD) therapy. The aim of the present study was to determine the prevalence of PNP, independent of other etiologies, and to determine the relationship to demographic and clinical factors in LD-treated Parkinson's patients. A total of 102 patients (51 patients with PD and 51 sex- and age-matched healthy controls) were enrolled in the study. The presence of any risk factors for PNP, ascertained from the history and laboratory tests, was an exclusion criterion. The Toronto Clinical Scoring System (TCSS) was used for clinical assessment of PNP. The objective assessment was based on electroneurography (ENG) studies in which motor nerves (peroneal and tibial nerves) as well as sensory nerves (sural and superficial peroneal nerves) were bilaterally examined. The severity of the disease was determined using the UPDRS scale (Unified Parkinson's Disease Rating Scale) and the Hoehn-Yahr (H-Y) scale. In the PD group, the clinical and neurophysiological indicators of PNP, manifested as a symmetrical and predominantly sensory axonal neuropathy, were more frequent then in the control group and observed in 43.1% vs. 13.7% and 15.7% vs. 2% of subjects respectively. The presence of PNP correlated with age and the severity of PD. Patients with PD and PNP had a higher level of Hcy as compared to PD patients without PNP, however the difference was not statistically significant. The frequency of PNP in PD patients is higher than in controls. The characteristics and discrepancy between the number of patients with clinical and ENG detected PNP may suggest the small fiber neuropathy (SFN) as the dominant form of neuropathy in PD patients.

    Interleukin-21 (IL-21) is a common γ-chain cytokine produced by T helper and natural killer T (NKT) cells. It has been shown to regulate the response of various lymphocyte subsets including NK, NKT, T and B cells. Owing to its potent anti-tumor function in preclinical studies and its ability to induce cytotoxicity and interferon-γ (IFN-γ) production in NK and CD8 T cells, recombinant IL-21 (rIL-21) was fast-tracked into early-phase clinical trials of patients with various malignancies. In a phase 2a trial of patients with metastatic melanoma, we analyzed the frequency and function of NKT cells in patients receiving rIL-21. NKT cells were present at a low frequency, but their levels were relatively stable in patients administered rIL-21. Unlike our observations in NK and CD8 T cells, rIL-21 appeared to reduce IFN-γ and TNF production by NKT cells, whereas it enhanced IL-4 production. It also modulated the expression of cell surface markers, specifically on CD4(-) NKT cells. In addition, an increase in CD3(+)CD56(+) NKT-like cells was observed over the course of rIL-21 administration. These results highlight that IL-21 is a potent regulator of NKT cell function in vivo.

    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.

    FDG PET/CT is an excellent tool to detect melanoma metastases and also allows quantification of FDG uptake using standardized uptake value (SUV). The aim of this study was to prospectively investigate the potential prognostic value of SUV for disease-free survival (DFS) and disease-specific survival (DSS) for patients with stage IIIB melanoma. From November 2003 to March 2008, all consecutive patients were included in the present study. Inclusion criteria were: palpable, histology- or cytology-proven lymph node metastases of melanoma, and referred to the University Medical Centre Groningen for FDG PET and CT examination. Patients without distant metastases were evaluated. Multivariable survival analysis was performed to determine whether SUV was associated with DFS and DSS (Cox proportional hazard analysis). In 80 patients (without distant metastases, 65 %) SUV could be measured. Overall 5-year DFS was 41 % (95% CI 26-56 %) and 24 % (95% CI 12-38 %) in patients with a low and high SUVmean (p = 0.02), respectively. Overall 5-year DSS was 48 % (95% CI 31-62 %) and 30 % (95% CI 17-45 %) in patients with a low and high SUVmean (p = 0.04), respectively. In the multivariable analysis, SUVmean was associated with DFS (hazard ratio 1.7; p = 0.048), but was not associated with DSS (hazard ratio 1.6; p = 0.1). The number of positive nodes, extranodal growth and gender were also associated with survival. FDG uptake in clinically overt nodal melanoma metastases is inversely associated with DFS. Univariate analysis showed an association with DSS. However, after adjustment for potential confounders this association was no longer significant. If these findings are confirmed in larger studies, SUVmean could potentially be used (in addition to the number of positive nodes, tumour size and extranodal growth) as a factor in deciding on adjuvant systemic treatment.

    To retrospectively study the influence of nodal tumour burden on lymphoscintigraphic imaging in 509 consecutive patients with melanomas. Bidirectional lymphatic drainage, the clear depiction of an afferent lymphatic vessel, time to depiction of the first sentinel lymph node (SLN) and number of depicted and excised nodes were recorded. Nodal tumour load was classified as SLN-negative, SLN micrometastases or macrometastases. In the overall population, using multivariate regression analysis, a short SLN depiction time was significantly associated with the depiction of a greater number of radioactive nodes, a short distance between the primary tumour site and the nodal basin, younger age and lower nodal tumour burden. The proportion of patients with clear depiction of an afferent lymphatic vessel depended on the nodal tumour load (46 % in SLN-negative patients, 57 % in SLN positive patients, and 69 % in patients with macrometastases; P = 0.009). Macrometastasis was significantly associated with delayed depiction of the first radioactive node and a greater number of depicted hotspots. In patients with clinically nonsuspicious nodes, i.e. the classical target group for SLN biopsy, clear depiction of an afferent vessel was significantly associated with a higher number of SLNs during dynamic acquisition, SLN micrometastasis and a higher overall number of metastatic lymph nodes after SLN biopsy plus completion lymphadenectomy. The excision of more than two SLNs did not increase the metastasis detection rate. In patients with bidirectional or tridirectional lymphatic drainage, the SLN positivity rates for the first, second and third basin were 25.4 %, 11.7 % and 0.0 %, respectively (P = 0.002). In patients with clinically nonsuspicious lymph nodes, clear depiction of an afferent lymph vessel may be a sign of micrometastasis. Macrometastasis is associated with prominent afferent vessels, delayed depiction of the first radioactive node and a higher number of depicted hotspots

    Molecular biology-based ultrastaging of cancer is already part of the standard management of patients with hematologic malignancies, whereas the evidence for solid tumors is much more debated. Polymerase chain reaction (PCR) -based detection of melanoma cells in sentinel lymph nodes (SLN) of patients with melanoma represents an appealing prognostic tool. However, no consensus exists on the clinical implementation of this prognostic indicator for the management of these patients. Twenty-two studies enrolling 4,019 patients who underwent SLN biopsy for clinical stage I to II cutaneous melanoma were reviewed. Correlation of PCR status with TNM stage, disease recurrence rates, and survival was assessed by means of association statistics and formal meta-analysis, respectively. PCR status correlated with both TNM stage (stage I to II v III; PCR positivity, 95.1% v 46.6%; P < .0001) and disease recurrence (PCR positive v negative; relapse rate, 16.8% v 8.7%; P < .0001). PCR positivity was also associated with worse overall (hazard ratio [HR], 5.08; 95% CI, 1.83 to 14.08; P = .002) and disease-free (HR, 3.41; 95% CI, 1.86 to 6.24; P < .0001) survival. Statistical heterogeneity was significant, underscoring the variability among overall effect estimates across studies; metaregression and subgroup analysis did not identify clear-cut sources of heterogeneity, although some study design variables were suggested as potential causes. PCR status of SLN appears to have a clinically valuable prognostic power in patients with melanoma. Although the heterogeneity of the studies so far published warrants caution to avoid overestimating the favorable results of pooled data, our findings strongly support additional investigation in this field.

    Purpose: Choroidal melanomas usually present a characteristic appearance in MRI. Differing characteristics can cause problems in differential diagnosis between melanomas and other masses in the globe. The purpose of this study was to evaluate the appearance of choroidal melanomas with MRI in a large consecutive patient group. Methods: In a prospective study, 200 patients with choroidal melanomas were investigated with MRI using a 1.5 T scanner and a 5 cm surface coil. Both quantitative and qualitative evaluation of the resulting images was performed. Results: 78.5% of the melanomas presented with homogeneous signal intensities within the tumor due to a homogeneous pigmentation whereas 21.5% of the melanomas demonstrated a mixed pigmentation. Signal intensities of the homogeneous melanomas in the plain T 1 -WI were moderately or markedly hyperintense compared to the vitreous in 29.3% and moderately or markedly hypointense in the T 2 -WI in 37.1%. An accompanying retinal detachment was found in 65.5% and an extraocular growth in 7.0%. Conclusions: In 10% to 37% we observed the typical well known MR appearance, including homogenous high signal in the T 1 -WI and low signals in the T 2 -WI. For further differentiation, morphological criteria (e.g. shape, size, and position) were used, which are also discussed. (orig.) [de

    Cerebral metastases are a common cause of death in patients with melanoma. Systemic drug treatment of these metastases is rarely effective, and where possible surgical resection and/or stereotactic radiosurgery (SRS) are the preferred treatment options. Treatment with adjuvant whole brain radiotherapy (WBRT) following neurosurgery and/or SRS is controversial. Proponents of WBRT report prolongation of intracranial control with reduced neurological events and better palliation. Opponents state melanoma is radioresistant; that WBRT yields no survival benefit and may impair neurocognitive function. These opinions are based largely on studies in other tumour types in which assessment of neurocognitive function has been incomplete. This trial is an international, prospective multi-centre, open-label, phase III randomised controlled trial comparing WBRT to observation following local treatment of intracranial melanoma metastases with surgery and/or SRS. Patients aged 18 years or older with 1-3 brain metastases excised and/or stereotactically irradiated and an ECOG status of 0-2 are eligible. Patients with leptomeningeal disease, or who have had previous WBRT or localised treatment for brain metastases are ineligible. WBRT prescription is at least 30 Gy in 10 fractions commenced within 8 weeks of surgery and/or SRS. Randomisation is stratified by the number of cerebral metastases, presence or absence of extracranial disease, treatment centre, sex, radiotherapy dose and patient age. The primary endpoint is the proportion of patients with distant intracranial failure as determined by MRI assessment at 12 months. Secondary end points include: survival, quality of life, performance status and neurocognitive function. Accrual to previous trials for patients with brain metastases has been difficult, mainly due to referral bias for or against WBRT. This trial should provide the evidence that is currently lacking in treatment decision-making for patients with melanoma brain

    -related adverse events of grade 3 or worse occurred in 38 (22%) patients. Eleven (6%) patients developed squamous-cell carcinoma (five [6%] patients in cohort A, of whom one also had keratoacanthoma; six [7%] in cohort B). Four grade 4 treatment-related adverse events occurred in cohort A: one blood amylase increase, one convulsion, one lipase increase, and one neutropenia. Two grade 4 events occurred in cohort B: one agranulocytosis and one intracranial haemorrhage. 51 (30%) patients had a serious adverse event. The three most frequent serious adverse events were pyrexia (ten [6%] patients), intracranial haemorrhage (ten [6%]; one treatment-related), and squamous-cell carcinoma (11 [6%]).

    2014-01-01

    Uveal melanoma is the most common primary intraocular malignancy in adults, with an incidence of 5-7 per million per year. It is associated with the development of metastasis in about 50% of cases, and 40% of patients with uveal melanoma die of metastatic disease despite successful treatment of the primary tumour. The survival rates at 5, 10 and 15 years are 65%, 50% and 45% respectively. Unlike progress made in many other areas of cancer, uveal melanoma is still poorly understood and survival rates have remained similar over the past 25 years. Recently, advances made in molecular genetics have improved our understanding of this disease and stratification of patients into low risk and high risk for developing metastasis. However, only a limited number of studies have been performed using proteomic methods. This review will give an overview of various proteomic technologies currently employed in life sciences research, and discuss proteomic studies of uveal melanoma.

    To quantify the impact of excision margins on disease-specific survival of patients with primary cutaneous melanoma. Current guidelines recommend narrow margins for the treatment of primary melanoma, although available evidence on this subject is not unequivocal and not always appropriately analyzed. A systematic review of randomized controlled trials (RCT) addressing the issue of wide versus narrow excision margins was performed. Meta-analysis methods for time-to-event data were used to extract hazard ratios(HR) and their 95% confidence intervals (CI) from eligible studies, and ultimately to estimate the summary effect of excision margins on patients' survival. The 5 eligible RCT enrolled a total of 3295 patients who were allocated to wide (3-5 cm) or narrow (1-2 cm) excision of their primary tumor. The data of locoregional disease-free (LDFS), disease-free (DFS),disease-specific (DSS), and overall (OS) survival were available for 3, 5, 3, and 5 RCT, respectively. The meta-analysis suggested that narrow margins might be associated with an increased risk of both locoregional disease recurrence (HR: 1.30, CI: 1.07-1.57; P = 0.01) and death by disease (HR: 1.28, CI:1.07-1.53, P = 0.01). As regards DFS, the borderline disadvantage (HR:1.13, CI: 0.995-1.28; P = 0.06) becomes significant when considering RCT that enrolled patients with thicker melanoma (HR: 1.19, CI: 1.02-1.39, P =0.03). When death by any cause (OS) was analyzed, no risk difference was found. The lack of DSS data from all the available RCT does not allow to draw definitive conclusions. However, current evidence appears sufficient to question the common belief that narrow excision margins are as safe as wide margins in the management of primary melanoma, that calls for further investigation in this field.

    Purpose: Surgically resected melanoma patients with high-risk features commonly receive adjuvant therapy with interferon-alpha 2b combined with radiation therapy; the purpose of our study was to evaluate the potential enhancement of radiation toxicity by interferon. Methods and Materials: Patients at LDS Hospital and the University of Utah Medical Center in Salt Lake City treated with interferon during radiotherapy or within 1 month of its completion were retrospectively identified, and their charts were reviewed. If possible, the patients were asked to return to the LDS Hospital radiation therapy department for follow-up. Results: Five of 10 patients receiving interferon-alpha 2b therapy during radiation therapy or within 1 month of its completion experienced severe subacute/late complications of therapy. Severe subacute/late complications included two patients with peripheral neuropathy, one patient with radiation necrosis in the brain, and two patients with radiation necrosis in the s.c. tissue. One patient with peripheral neuropathy and one patient with radiation necrosis also developed lymphedema. Conclusions: In vitro studies have identified a radiosensitizing effect by interferon-alpha on certain cell lines, which suggests the possibility that patients treated with interferon and radiation therapy may experience more severe radiation toxicities. We have observed severe subacute/late complications in five of 10 patients treated with interferon-alpha 2b during radiation therapy or within 1 month of its completion. Although an observational study of 10 patients lacks the statistic power to reach conclusions regarding the safety and complication rates of combined interferon and radiation therapy, it is sufficient to raise concerns and suggest the need for prospective studies

    This work is part of a multicentric European evaluation of the monoclonal antibody 225.28s targeted against malignant melanoma and its metastases. Twenty-eight patients (12 males, 16 females, mean age: 53 yrs), who had initially been treated by resection of the primary tumour, were included in the study. Twenty-three of the 26 metastases more than 1 cm in diameter were visualized by immunoscintigraphy. The sensitivity of the procedure (88%) is limited however by the small size of the lesions and their depth, as well as by background noise caused by circulating antibodies. Immunoscintigraphy enables non-invasive investigation of the whole body and can detect lesions that other conventional complementary explorations fail to identify [fr

    The aim of the present study was to prove the prognostic value of the SLN-concept in these patients. Methods: So far the clinical follow-up of 162 patients with histologically proven malignant melanoma and metastatically uninvolved (negative) SLN was investigated. Histological examination included standard methods (HE-Test) and special histochemical techniques (S-100, HMB-45). All patients underwent clinical examination, ultrasonic diagnosis of the regional lymph nodes, and X-ray of the chest every 3 months. Results: Despite of negative SLN-findings in 8/162 patients metastases of the malignant melanoma were found after a time period of 5-27 months. Three patients presented with recurrence in the previously mapped (negative) SLN-basin. In another case the scintigraphically visualized SLN could not be identified intraoperatively by means of the hand-held gamma probe. One patient showed intransit-metastases or skin-metastases, respectively; another patient recurred in the scar area. One patient showed hematogenic dissemination (liver) which is not detectable by lymphoscintigraphy; in another patient metastases were found outside the primary lymphatic basin (cervical). Conclusion: In our patient group 4,9% presented with metastases despite negative SLN while published data report up to 11% (observation period 35 months), among them only 3 patients (1,9%) being real concept failures. Our results underline that there is no evidence to change this concept in patients with clinically early stage. (orig.) [de

    Miliary brain metastases are a rare condition but associated with an exceedingly poor prognosis. We present the case of a patient suffering from malignant melanoma with an acute progressively worsening of neurological symptoms up to the loss of consciousness. The magnetic resonance imaging (MRI) demonstrated a new onset of disseminated, miliary spread of central nervous system metastases from a malignant melanoma within 4 days. We report on a 57-year-old woman suffering from metastatic malignant melanoma positive for BRAF-V600E mutation who developed an acute onset of neurological symptoms. The patient received vemurafenib and dacarbacin as chemotherapeutic regime for treatment of malignant melanoma. After admission to our hospital due to progressive disturbance of memory and speech difficulty a magnetic resonance tomography (MRI) was performed. This showed no evidence of cerebral tumour manifestation. The symptoms progressed until a loss of consciousness occurred on day five after admission and the patient was admitted to our intensive care unit for orotracheal intubation. No evidence for infectious, metabolic or autoimmune cerebral disorders was found. Due to the inexplicable acute worsening of the neurological symptoms a second MRI was performed on day five. This revealed a new onset of innumerable contrast-enhancing miliary lesions, especially in the grey matter which was proven as metastases from malignant melanoma on histopathology. This case describes an unique hyperacute onset of tumour progression correlating with an acute deterioration of neurological symptoms in a patient suffering from miliary brain metastasis from BRAF positive malignant melanoma

    A 57-year-old woman was referred to our regional sarcoma unit following a 2-year history of a progressively enlarging mass on her right forearm. At 14 × 7 × 12 cm, this mass turned out to be one of the largest upper limb cutaneous malignant melanomas ever described, and, to the best of our knowledge, the first documented in the UK. Remarkably, despite having a T4 malignant tumour with a Breslow thickness of 70 mm, this patient is still alive over 4 years later with no locoregional or distant metastatic spread. We present our experience in the management of this giant malignant melanoma of the upper limb and consider important differentials. 2016 BMJ Publishing Group Ltd.

    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.

    In 2010, the American Diabetes Association (ADA) proposed that individuals with fasting glucose level of 100-125 mg/dL (5.6-6.9 mmol/L) or glucose level of 140-199 mg/dL (7.8-11.0 mmol/L) 2 hours after a 75-g oral glucose tolerance test or hemoglobin A(1c) 5.7%-6.4% be classified as prediabetic, indicating increased risk for the emergence of diabetes mellitus. At the same time, the ADA formulated guidelines for the use of metformin for the treatment of prediabetes. To determine the prevalence of prediabetes in a cohort of psychiatrically ill adults receiving antipsychotics and to compare the clinical and metabolic features of prediabetic patients with those of patients with normal glucose tolerance and those with diabetes mellitus. The 2010 ADA criteria were applied to a large, consecutive, single-site European cohort of 783 adult psychiatric inpatients (mean age: 37.6 years) without a history of diabetes who were receiving antipsychotics. All patients in this cross-sectional study underwent measurement of body mass index (BMI), waist circumference, oral glucose tolerance test, and fasting insulin and lipids from November 2003 through July 2007. 413 patients (52.8%) had normal glucose tolerance, 290 (37.0%) had prediabetes, and 80 (10.2%) had diabetes mellitus. The fasting glucose and/or hemoglobin A(1c) criteria were met by 89.7% of prediabetic patients.

    Purpose Uveal melanoma is the most common primary intraocular malignancy in adults with no effective systemic treatment option in the metastatic setting. Selumetinib (AZD6244, ARRY-142886) is an oral, potent, and selective MEK1/2 inhibitor with a short half-life, which demonstrated single-agent activity in patients with metastatic uveal melanoma in a randomized phase II trial. Methods The Selumetinib (AZD6244: ARRY-142886) (Hyd-Sulfate) in Metastatic Uveal Melanoma (SUMIT) study was a phase III, double-blind trial ( ClinicalTrial.gov identifier: NCT01974752) in which patients with metastatic uveal melanoma and no prior systemic therapy were randomly assigned (3:1) to selumetinib (75 mg twice daily) plus dacarbazine (1,000 mg/m 2 intravenously on day 1 of every 21-day cycle) or placebo plus dacarbazine. The primary end point was progression-free survival (PFS) by blinded independent central radiologic review. Secondary end points included overall survival and objective response rate. Results A total of 129 patients were randomly assigned to receive selumetinib plus dacarbazine (n = 97) or placebo plus dacarbazine (n = 32). In the selumetinib plus dacarbazine group, 82 patients (85%) experienced a PFS event, compared with 24 (75%) in the placebo plus dacarbazine group (median, 2.8 v 1.8 months); the hazard ratio for PFS was 0.78 (95% CI, 0.48 to 1.27; two-sided P = .32). The objective response rate was 3% with selumetinib plus dacarbazine and 0% with placebo plus dacarbazine (two-sided P = .36). At 37% maturity (n = 48 deaths), analysis of overall survival gave a hazard ratio of 0.75 (95% CI, 0.39 to 1.46; two-sided P = .40). The most frequently reported adverse events (selumetinib plus dacarbazine v placebo plus dacarbazine) were nausea (62% v 19%), rash (57% v 6%), fatigue (44% v 47%), diarrhea (44% v 22%), and peripheral edema (43% v 6%). Conclusion In patients with metastatic uveal melanoma, the combination of selumetinib plus dacarbazine had a tolerable safety

    Melanoma is the most aggressive and deadly type of skin cancer. Surgical resection with or without lymph node sampling is the standard of care for primary cutaneous melanoma. Adjuvant therapy decisions may be informed by careful consideration of prognostic factors. High-dose adjuvant interferon alpha-2b increases disease-free survival and may modestly improve overall survival. Less toxic alternatives for adjuvant therapy are currently under study. External beam radiation therapy is an option for nodal beds where the risk of local recurrence is very high. In-transit melanoma metastases may be treated locally with surgery, immunotherapy, radiation, or heated limb perfusion. For metastatic melanoma, the options include chemotherapy or immunotherapy; targeted anti-BRAF and anti-KIT therapy is under active investigation. Standard chemotherapy yields objective tumor responses in approximately 10%–20% of patients, and sustained remissions are uncommon. Immunotherapy with high-dose interleukin-2 yields objective tumor responses in a minority of patients; however, some of these responses may be durable. Identification of activating mutations of BRAF, NRAS, c-KIT, and GNAQ in distinct clinical subtypes of melanoma suggest that these are molecularly distinct. Emerging data from clinical trials suggest that substantial improvements in the standard of care for melanoma may be possible

    Isolated, hyperthermic limb perfusion (ILP) with recombinant human tumor necrosis factor alpha and melphalan is a highly effective treatment for advanced soft tissue sarcoma (STS) and locoregional metastatic malignant melanoma. Multidrug resistance (MDR)-associated genes are known to be inducible by heat and drugs; expression levels of the major vault protein (MVP), MDR1, and MDR-associated protein 1 (MRP1) were determined sequentially before, during, and after ILP of patients. Twenty-one STS or malignant melanoma patients were treated by ILP. Tumor tissue temperatures were recorded continuously and ranged from 33.4 degrees C initially to peak values of 40.4 degrees C during ILP. Serial true-cut biopsy specimens from tumor tissues were routinely microdissected. Expression analyses for MDR genes were performed by real-time reverse transcriptase polymerase chain reaction and immunohistochemistry. In 83% of the patients, MVP expression was induced during hyperthermic ILP. MVP-mRNA inductions often paralleled the increase in temperature during ILP. Increased MVP protein expressions either were observed simultaneously with the MVP-mRNA induction or were delayed until after the induction at the transcriptional level. Inductions of MDR1 and MRP1 were observed in only 13% and 27% of the specimens analyzed. Temperatures and drugs applied preferentially led to an induction of MVP and were not sufficient to induce MDR1 and MRP1 in the majority of tumors. This study is the first to analyze the expression of MDR-associated genes sequentially during ILP of patients and demonstrates that treatment might lead to increased levels of MVP, whereas enhanced levels of MDR1 and MRP1 remain rare events.

    Based on previous meta-analyses of randomized controlled trials (RCTs), the use of interferon alpha (IFN-alpha) in the adjuvant setting improves disease-free survival (DFS) in patients with high-risk cutaneous melanoma. However, RCTs have yielded conflicting data on the effect of IFN-alpha on overall survival (OS). We conducted a systematic review and meta-analysis to examine the effect of IFN-alpha on DFS and OS in patients with high-risk cutaneous melanoma. The systematic review was performed by searching MEDLINE, EMBASE, Cancerlit, Cochrane, ISI Web of Science, and ASCO databases. The meta-analysis was performed using time-to-event data from which hazard ratios (HRs) and 95% confidence intervals (CIs) of DFS and OS were estimated. Subgroup and meta-regression analyses to investigate the effect of dose and treatment duration were also performed. Statistical tests were two-sided. The meta-analysis included 14 RCTs, published between 1990 and 2008, and involved 8122 patients, of which 4362 patients were allocated to the IFN-alpha arm. IFN-alpha alone was compared with observation in 12 of the 14 trials, and 17 comparisons (IFN-alpha vs comparator) were generated in total. IFN-alpha treatment was associated with a statistically significant improvement in DFS in 10 of the 17 comparisons (HR for disease recurrence = 0.82, 95% CI = 0.77 to 0.87; P < .001) and improved OS in four of the 14 comparisons (HR for death = 0.89, 95% CI = 0.83 to 0.96; P = .002). No between-study heterogeneity in either DFS or OS was observed. No optimal IFN-alpha dose and/or treatment duration or a subset of patients more responsive to adjuvant therapy was identified using subgroup analysis and meta-regression. In patients with high-risk cutaneous melanoma, IFN-alpha adjuvant treatment showed statistically significant improvement in both DFS and OS.

The median overall survival (OS was longer versus GM-CSF in patients with earlier-stage melanoma (IIIB–IVM1a. Here, we report a detailed subgroup analysis of the OPTiM study in patients with IIIB–IVM1a disease. Patients and methods: The patients were randomized (2:1 ratio to intralesional talimogene laherparepvec or subcutaneous GM-CSF and were evaluated for DRR, overall response rate (ORR, OS, safety, benefit–risk and numbers needed to treat. Descriptive statistics were used for subgroup comparisons. Results: Among 249 evaluated patients with stage IIIB–IVM1a melanoma, DRR was higher with talimogene laherparepvec compared with GM-CSF (25.2% versus 1.2%; P<0.0001. ORR was also higher in the talimogene laherparepvec arm (40.5% versus 2.3%; P<0.0001, and 27 patients in the talimogene laherparepvec arm had a complete response, compared with none in GM-CSF-treated patients. The incidence rates of exposure-adjusted adverse events (AE and serious AEs were similar with both treatments. Conclusion

    Neovascular glaucoma developed in 22 of 169 uveal melanoma patients treated with helium ion irradiation. Most patients had large melanomas; no eyes containing small melanomas developed anterior segment neovascularization. The mean onset of glaucoma was 14.1 months (range, 7-31 months). The incidence of anterior segment neovascularization increased with radiation dosage; there was an approximately three-fold increase at 80 GyE versus 60 GyE of helium ion radiation (23% vs. 8.5%) (P less than 0.05). Neovascular glaucoma occurred more commonly in larger tumors; the incidence was not affected by tumor location, presence of subretinal fluid, nor rate of tumor regression. Fifty-three percent of patients had some response with intraocular pressures of 21 mmHg or less to a combination of antiglaucoma treatments

    Associations of MC1R with BRAF mutations in melanoma have been inconsistent between studies. We sought to determine for 1,227 participants in the international population-based Genes, Environment, and Melanoma (GEM) study whether MC1R and phenotypes were associated with melanoma BRAF/NRAS subtypes. We used logistic regression adjusted by age, sex, and study design features and examined effect modifications. BRAF + were associated with younger age, blond/light brown hair, increased nevi, and less freckling, and NRAS + with older age relative to the wild type (BRAF - /NRAS - ) melanomas (all P < 0.05). Comparing specific BRAF subtypes to the wild type, BRAF V600E was associated with younger age, blond/light brown hair, and increased nevi and V600K with increased nevi and less freckling (all P < 0.05). MC1R was positively associated with BRAF V600E cases but only among individuals with darker phototypes or darker hair (P interaction < 0.05) but inversely associated with BRAF V600K (P trend  = 0.006) with no significant effect modification by phenotypes. These results support distinct etiologies for BRAF V600E, BRAF V600K, NRAS + , and wild-type melanomas. MC1R's associations with BRAF V600E cases limited to individuals with darker phenotypes indicate that MC1R genotypes specifically provide information about BRAF V600E melanoma risk in those not considered high risk based on phenotype. Our results also suggest that melanin pathways deserve further study in BRAF V600E melanomagenesis. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

    The treatment modalities for uveal melanoma (UM) include surgery and radiotherapy (RT). The utilization of RT as a strategy for organ preservation has been increasing, but the survival difference between the two aforementioned treatment modalities has not been reported. An observational and cohort study was performed using a propensity score with an already existing public database. Patients diagnosed with UM within the period from 2004-2013 were selected from the Surveillance, Epidemiology, and End Results (SEER) database. One-to-one matching and inverse probability of treatment weighting (IPTW) using the propensity score were used to estimate and compare survival rates. Overall, 3291 patients were treated: 2503 received RT only (RT group) and 788 received surgical resection only (surgery group). The RT group had an improved crude 5-year overall survival (OS) rate compared with the surgery group (76% vs. 60%, P < 0.001), and an improved 5-year melanoma-specific survival (MSS) rate (89% vs. 73%, P < 0.001). Compared to the surgery group, the RT group was associated with improved OS (hazard ratio [HR] 0.52, 95% confidence interval [CI] 0.38-0.73, P < 0.001) and MSS (HR 0.48, 95% CI 0.35-0.65, P < 0.001) in the matched cohort. The survival benefit of the RT group maintained after adjustment with IPTW, both in OS and MSS. To our knowledge, the present study was the first to demonstrate the survival difference between the two treatment modalities for UM using both the propensity score matching and weighting methods with the SEER database. The current study suggests that RT may provide a survival advantage over surgery in the treatment of UM. (orig.)

To date, relatively few case series of UM have been published. Moreover, the factors influencing survival remain largely unknown. This study sought to analyze the impact of demographics, histology, clinical presentation, and treatments on the clinical outcomes of UM in a large modern nationwide patient cohort.Methods: Demographics and clinical data were abstracted on 277,120 histologically confirmed melanoma patients from the Surveillance, Epidemiology, and End Results database between 1973 and 2012.Results: A total of 7,516 cases of UM represented 3.2% of all recorded cases of melanoma. The mean age-adjusted incidence was 5.1 per million (95% CI 4.2–6.1 and was higher in males (5.9, CI =4.4–7.6 compared to females (4.5, CI =3.3–5.8, P<0.001. UM occurred most commonly in the sixth decade of life (61.4±15 and among Caucasians (94.7%. A total of 52.3% of cases were reported in the Western US (35.7% in California. The initial diagnoses in 65.2% of cases were by histopathology, followed by clinical diagnosis (18.8% and radiographic imaging (16.0%. The percentage of UM cases managed by surgery alone decreased by 69.4% between the 1973–1977 and 2006–2012 time periods, concomitant with a 62% increase in primary radiotherapy, P<0.001. The UM mean overall and cancer-specific 5-year relative survival rates were 79.8%±5.8% and 76%±5.3%, respectively. The mean 5-year cancer-specific survival rate (76% remained stable during the study period between 1973 and 2012. The mean survival for patients treated with

    Aim. The aims of this paper were to evaluate the clinical relevance of lymphoscintigraphy with intraoperative gamma-probe detection in identifying sentinel nodes (SNs) and to study the prognostic value of SN biopsy in head and neck melanoma patients. Methods. Sixty-one patients had lymphoscintigraphy with intradermal injections of 99m Tc-Nanocoll (40 MBq), 24 h before surgery. Tumor-positive SNs patients underwent total lymph node dissection Postoperative histological examination was performed. Patients were followed up for 1 to 5 years (median 3 years). The tumor relapses and the overall survival were evaluated by means of statistical methods. Results. Lymphoscintigraphy showed lymphatic distribution to more than one basin in 45 patients (74%), in 15 patients one basin was visualized and no basin in 1 patient. In 41 patients the SN was negative for metastases, while in 20 was positive. In a high percentage of patients (30%), metastatic involvement occurred in more than one lymph node basin. During follow-up in the negative SN group, 40 patients remained disease free and 1 relapsed. In the positive SN group, 10 patients remained disease free and 10 relapsed. Recurrence time ranged from 6 to 11 months. The overall survival of the SNs negative group was significantly higher than the positive SN group. Conclusion. This approach was able to distinguish: a) patients with tumor-negative SNs with a favorable clinical course (98% did not relapse, P<0.001); b) patients with tumor-positive SNs with a high rate of tumor relapse (50%, P<0.001). Therefore SN biopsy may give information about prognosis in head and neck melanoma patients

    The nationwide Danish Cancer Registry and the Danish Melanoma Database both record data on melanoma for purposes of monitoring, quality assurance, and research. However, the data quality of the Cancer Registry and the Melanoma Database has not been formally evaluated. We estimated the positive predictive value (PPV) of melanoma diagnosis for random samples of 200 patients from the Cancer Registry (n = 200) and the Melanoma Database (n = 200) during 2004-2014, using the Danish Pathology Registry as "gold standard" reference. We further validated tumor characteristics in the Cancer Registry and the Melanoma Database. Additionally, we estimated the PPV of in situ melanoma diagnoses in the Melanoma Database, and the sensitivity of melanoma diagnoses in 2004-2014. The PPVs of melanoma in the Cancer Registry and the Melanoma Database were 97% (95% CI = 94, 99) and 100%. The sensitivity was 90% in the Cancer Registry and 77% in the Melanoma Database. The PPV of in situ melanomas in the Melanoma Database was 97% and the sensitivity was 56%. In the Melanoma Database, we observed PPVs of ulceration of 75% and Breslow thickness of 96%. The PPV of histologic subtypes varied between 87% and 100% in the Cancer Registry and 93% and 100% in the Melanoma Database. The PPVs for anatomical localization were 83%-95% in the Cancer Registry and 93%-100% in the Melanoma Database. The data quality in both the Cancer Registry and the Melanoma Database is high, supporting their use in epidemiologic studies.

    Melanoma is the fifth most common cancer in the UK. Incidence rates have quadrupled over the last 30 years and continue to rise, especially among younger people. As routine screening of the general population is not currently recommended in the UK, a focus on secondary prevention through early detection and prompt treatment in individuals at increased risk of melanoma could make an important contribution to improve melanoma outcomes. This paper describes the protocol for a phase II, multisite, randomised controlled trial, in the primary care setting, for patients at increased risk of melanoma. A skin self-monitoring (SSM) smartphone 'App' was used to improve symptom appraisal and encourage help seeking in primary care, thereby promoting early presentation with skin changes suspicious of melanoma. We aim to recruit 200 participants from general practice waiting rooms in the East of England. Eligible patients are those identified at higher melanoma risk (using a real-time risk assessment tool), without a personal history of melanoma, aged 18 to 75 years. Participants will be invited to a primary care nurse consultation, and randomised to the intervention group (standard written advice on skin cancer detection and sun protection, loading of an SSM 'App' onto the participant's smartphone and instructions on use including self-monitoring reminders) or control group (standard written advice alone). The primary outcomes are consultation rates for changes to a pigmented skin lesion, and the patient interval (time from first noticing a skin change to consultation). Secondary outcomes include patient sun protection behaviours, psychosocial outcomes, and measures of trial feasibility and acceptability.

    Currently, uveal melanoma is not considered within the Lynch syndrome tumor spectrum. However, there are studies suggesting a contribution of microsatellite instability in sporadic uveal melanoma tumorigenesis. We report a 45-year-old woman who was referred for genetic counseling due to a family history of Lynch syndrome caused by a MLH1 mutation. She originally underwent enucleation of the right eye secondary to a uveal spindle cell melanoma diagnosed at age 25. The tumor recurred 22 years later presenting as an ovarian metastasis and concurrently a microscopic endometrial endometrioid carcinoma, grade 1/3 was diagnosed. Subsequent studies highlighted that the uveal melanoma showed high microsatellite instability and loss of MLH1 and PMS2 protein expression, with no MLH1 promoter methylation or BRAF mutation. Additionally, a GNAQ mutation was found. We conclude that our patient's uveal melanoma is most likely related to MLH1 germline mutation and thus Lynch syndrome related. To the best of our knowledge, this is the first report of uveal melanoma showing MLH1/PMS2 protein loss in the context of Lynch syndrome.

    The relationship between tumour volume response and cell kill in B16 melanoma following treatment in vivo with cyclophosphamide (CY) and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) was investigated. Tumour volume response, expressed as growth delay, was estimated from measurements of tumour dimensions. Depression of in vitro colony-forming ability of cells from treated tumours was used as the measure of tumour cell kill. The relationship between these parameters was clearly different for the two agents studied. CY produced more growth delay (7.5 days) per decade of tumour cell kill than CCNU (2 to 3.5 days). The possibility that this was due to a technical artefact was rejected in favour of an alternative explanation that different rates of cellular repopulation in tumours treated with CY and CCNU might be responsible. Cellular repopulation was measured directly, by performing cell-survival assays at various times after treatment with doses of CY and CCNU which produced about 3 decades of cell kill. The rate of repopulation by clonogenic cells was much slower after treatment with CY than with CCNU, and this appears to account for the longer duration of the growth delay obtained with CY.

    The detection of circulating tumor cells (CTC) in patients with melanoma represents an appealing prognostic tool, but no consensus exists on this topic. We aimed to comprehensively and quantitatively summarize the evidence for the use of CTC to predict patients' clinical outcome. Fifty-three studies enrolling 5,433 patients were reviewed. Correlation of CTC status with tumor-node-metastasis disease stage and patients' overall (OS) and progression-free (PFS) survival was assessed by means of association statistics and meta-analysis, respectively. CTC status correlated with both tumor-node-metastasis stage (stage I, 32%; stage II, 41.7%; stage III, 41.1%; stage IV, 47.4%; P(trend) < 0.0001) and survival (OS: hazard ratio, 2.42; 95% confidence interval, 1.7-3.45, P < 0.0001; PFS: hazard ratio, 2.45; 95% confidence interval, 1.78-3.38; P < 0.0001). However, statistical heterogeneity was significant for both OS and PFS, likely underscoring the wide variability in study design. Furthermore, CTC positivity rates in early stages were higher and in the metastatic setting were lower than expected, which indicates an unsatisfactory accuracy of currently available CTC detection assays. Our findings suggest that CTC might have a clinically valuable prognostic power in patients with melanoma. However, the heterogeneity of the studies thus far published warrants caution not to overestimate the favorable results of pooled data.

    Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre......-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP......-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median...

    Full Text Available AIM: To find new biomarkers for uveal melanoma (UM by analyzing the serum peptidome profile. METHODS: Proteomic spectra in patients with UM before and after operation were analyzed and compared with those of healthy controls. Magnetic affinity beads were used to capture serum peptides and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF mass spectrometer were used to compile serum peptide profiles. RESULTS: A panel of 49 peptides were differentially expressed between UM patients and controls, of which 33 peptides were of higher intensities in patient group and 16 peptides were of higher intensities in control group. Based on combined use of these potential markers, peptides with mean molecular masses of 1467 and 9289.0 Da provide high sensitivity (83.3%, specificity (100% and accuracy rate (93.0% together to differentiate melanoma patients from healthy controls. At the time point of 6mo postoperatively, the levels of many peptides differentially expressed before surgery showed no more statistical difference between the patients and the control group. Fibrinogen α-chain precursors were identified as potential UM markers. CONCLUSION: We have shown that a convenient and fast proteomic technique, affinity bead separation and MALDI-TOF analysis combined with bioinformatic software, facilitates the identification of novel biomarkers for UM.

    To understand how nanomechanical stiffness affects metastatic potential, we studied the relationship between cell migration, a characteristic of metastasis, and cell stiffness using atomic force microscopy (AFM), which can measure stiffness (elasticity) of individual living cells. Migration and cell stiffness of three metastatic B16 melanoma variants (B16-F10, B16-BL6, and B16-F1 cells), and also effects of (-)-epigallocatechin gallate (EGCG), were studied using Transwell assay and AFM. Migration of B16-F10 and B16-BL6 cells was 3 and 2 times higher than that of B16-F1 cells in Transwell assay, and cell stiffness determined by AFM was also different among the three variants, although they have similar morphologies and the same growth rates: Means of Young's modulus were 350.8 ± 4.8 Pa for B16-F10 cells, 661.9 ± 16.5 Pa for B16-BL6 cells, and 727.2 ± 13.0 Pa for B16-F1 cells. AFM measurements revealed that highly motile B16-F10 cells have low cell stiffness, and low motile and metastatic B16-F1 cells have high cell stiffness: Nanomechanical stiffness is inversely correlated with migration potential. Treatment of highly motile B16-F10 cells with EGCG increased cell stiffness 2-fold and inhibited migration of the cells. Our study with AFM clearly demonstrates that cell stiffness is a reliable quantitative indicator of migration potential, and very likely metastatic potential, even in morphologically similar cells. And increased cell stiffness may be a key nanomechanical feature in inhibition of metastasis.

    The incidence of melanoma in Denmark has immensely increased over the last 10 years making Denmark a high risk country for melanoma. In the last two decades multiple public campaigns have sought to increase the awareness of melanoma. Family history of melanoma is a known major risk factor but previous studies have shown that self-reported family history of melanoma is highly inaccurate. These studies are 15 years old and we wanted to examine if a higher awareness of melanoma has increased the accuracy of self-reported family history of melanoma. We examined the family history of 181 melanoma probands who reported 199 cases of melanoma in relatives, of which 135 cases where in first degree relatives. We confirmed the diagnosis of melanoma in 77% of all relatives, and in 83% of first degree relatives. In 181 probands we validated the negative family history of melanoma in 748 first degree relatives and found only 1 case of melanoma which was not reported in a 3 case melanoma family. Melanoma patients in Denmark report family history of melanoma in first and second degree relatives with a high level of accuracy with a true positive predictive value between 77 and 87%. In 99% of probands reporting a negative family history of melanoma in first degree relatives this information is correct. In clinical practice we recommend that melanoma diagnosis in relatives should be verified if possible, but even unverified reported melanoma cases in relatives should be included in the indication of genetic testing and assessment of melanoma risk in the family.

    Full Text Available A locomotor stump was formed in 36 patients (28 women and 8 men, by implanting an endoprosthesis for enucleation of the eyeball with uveal melanoma (UM. The indication for endoprosthesis implantation was no signs of extrabulbar growth. A modified 17–19 mm silicone implant covered with strips from a dura mater graft and medical mesh fabric was used as an orbital implant. The follow-up was 3 to 72 months (mean 32.5 months. All the patients achieved a satisfactory cosmetic effect. None patient was found to have a recurrent orbital tumor. Out of the complications, anterior implant surface denudation was noted in 4 patients. Two patients developed metastases. The absence of recurrent orbital UM at a 6-year follow-up enables primary endoprosthetic replacement of the orbit for UM to be regarded as a safe and reasonable method for patient cosmetic rehabilitation.

    Psycho-neuro-immune research suggests an association between cancer outcomes and psychosocial distress. Objective criteria to determine patients' levels of distress are important to establish potential links to disease outcomes. We compared three patient-reported with one doctor-reported measures of psycho-oncologic distress frequently used in routine cancer care and investigated associations with standard disease severity parameters in melanoma patients. We enrolled n = 361 patients, successively seen at two outpatient university clinics in Germany. In the naturalistic study, n = 222 patients had been diagnosed 180 days and were in after-care (Group II). Across groups, only moderate associations were seen between patient- reported and doctor-reported measures. Regarding clinical variables, disease severity and perceived need of psycho-oncologic support reported by patients or doctors showed hardly any association. After subgroup stratification, in patients of Group II, patient-reported and doctor-reported instruments showed some small associations with disease parameters commonly linked to more rapid cancer progression in patients who are in cancer after-care. Overall, the few and low associations suggest that need of psycho-oncologic support and clinical variables were largely independent of each other and doctors' perception may not reflect the patient's view. Therefore, the assessment of the patient perspective is indispensable to ensure that melanoma patients receive appropriate support, as such need cannot be derived from other disease parameters or proxy report. More research is needed applying psychometrically robust instruments that are ideally combined with sensitive biomarkers to disentangle psycho-neuro-immune implications in melanoma patients.

    The research project, entitled ''Targeted Therapy for Melanoma,'' was focused on investigating the use of kidney protection measures to lower the non-specific kidney uptake of the radiolabeled Pb-DOTA-ReCCMSH peptide. Previous published work demonstrated that the kidney exhibited the highest non-target tissue uptake of the "2"1"2"P"b"/"2"0"3Pb radiolabeled melanoma targeting peptide DOTA-ReCCMSH. The radiolabeled alpha-melanocyte stimulating hormone (α-MSH) peptide analog DOTA-Re(Arg"1"1)CCMSH, which binds the melanocortin-1 receptor over-expressed on melanoma tumor cells, has shown promise as a PRRT agent in pre-clinical studies. High tumor uptake of "2"1"2Pb labeled DOTA-Re(Arg"1"1)CCMSH resulted in tumor reduction or eradication in melanoma therapy studies. Of particular note was the 20-50% cure rate observed when melanoma mice were treated with alpha particle emitter "2"1"2Pb. However, as with most PRRT agents, high radiation doses to the kidneys where observed. To optimize tumor treatment efficacy and reduce nephrotoxicity, the tumor to kidney uptake ratio must be improved. Strategies to reduce kidney retention of the radiolabeled peptide, while not effecting tumor uptake and retention, can be broken into several categories including modification of the targeting peptide sequence and reducing proximal tubule reabsorption.

    Many randomised trials assessing interferon-α (IFN-α) as adjuvant therapy for high-risk malignant melanoma have been undertaken. To better assess the role of IFN-α, an individual patient data (IPD) meta-analysis of these trials was undertaken. IPD was sought from all randomised trials of adjuvant IFN-α versus no IFN-α for high-risk melanoma. Primary outcomes were event-free survival (EFS) and overall survival (OS). Standard methods for quantitative IPD meta-analysis were used. Subgroup analyses by dose, duration of treatment and various patient and disease-specific parameters were performed. Fifteen trials were included in the analysis (eleven with IPD). EFS was significantly improved with IFN-α (hazard ratio [HR] = 0.86, CI 0.81-0.91; P meta-analysis provides clear evidence that adjuvant IFN-α significantly reduces the risk of relapse and improves survival and shows no benefit for higher doses compared to lower doses. The increased benefit in patients with ulcerated tumours, and lack of benefit in patients without ulceration, needs further investigation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Purpose. To describe the enhanced depth imaging optical coherence tomography (EDI-OCT findings in a patient with an extra macula choroidal melanoma before and after treatment. Methods. Observational case report. Results. A 45 year-old Caucasian male patient was referred to retina clinic for management of choroidal melanoma. Examination revealed a nasal choroidal melanoma while EDI-OCT illustrated subfoveal fluid pocket with elongated shaggy photoreceptors distant and separate from the tumor. The patient was treated with plaque brachytherapy and intravitreal bevacizumab. One week after plaque removal, there was a dramatic reduction in the shaggy photoreceptors. Conclusion. Choroidal melanomas have effects that are not localized to the area of the tumor. This loculated pocket of subretinal fluid and coinciding changes to photoreceptor morphology may be related to global changes in choroidal function or release of tumor related cytokines.

  6. Synchronous high-risk melanoma and lymphoid neoplasia.

    2012-02-03

    Large population-based studies have shown a significant association between melanoma and lymphoid neoplasia, particularly non-Hodgkin\\'s lymphoma (NHL) and chronic lymphocytic leukaemia (CLL), that is independent of any treatment received for the initial tumour. This study examines the presentation, diagnosis, treatment and progress of three patients who developed advanced melanoma concurrently with a lymphoid neoplasm (one NHL, two CLLs), in order to illustrate their association, discuss common aetiological factors and examine possible therapeutic options. As it is the melanoma rather than the lymphoid neoplasm that represents the bigger threat to overall survival, initial treatment should be targeted towards this cancer. However, because of the interplay between the diseases and the possible side-effects of the various treatments, the choice of adjuvant therapy requires careful consideration. Immunosuppression associated with chemotherapy may permit a more aggressive course for the melanoma, while locoregional radiotherapy is contraindicated following lymph node dissections. As immunotherapy is of benefit in the treatment of melanoma and has also been recently shown to be effective in the management of lymphoid neoplasia, we instituted interferon-alpha as adjuvant therapy for these patients, thereby utilizing a single agent to treat the dual pathologies. The three patients have now been followed-up for 6 months without evidence of disease recurrence or progression.

    Purpose: To evaluate the magnetic resonance (MR) imaging feature of suspected hepatic metastasis in patients with malignant melanoma which showed intermediate findings on screened contrast-enhanced computed tomography (CECT). Materials and methods: MR imaging was performed in 38 patients (22 men, 16 women; mean age, 58 years) whose CECT findings were intermediate. Hepatic metastases had been diagnosed on MR imaging in 23 of the 38 patients. Verification of hepatic metastasis was made by histological examination: ultrasonographic-guided needle biopsy (n = 3), autopsy (n = 3), and surgical resection (n = 1), or by an obvious progression in number and/or size of the lesions on follow-up MR imaging (n = 24). Two diagnostic radiologists reviewed MR images by consensus. The median follow-up duration was 14.2 months. Results: Abnormal findings were detected in 31 patients on MR images, and undetected in the remaining seven patients resulting in false-positive on CECT. The mean size of the lesion was 11.0 mm. False-positive results were obtained in two lesions which disappeared on follow-up MR imaging. In six patients, lesions were considered as hepatic cysts on MR images. As a result, a total of 35 hepatic metastases were detected on MR images. Of these, 18 patients demonstrated typical melanotic appearance on MR images which showed shortened T1 and T2 relaxation times, and five patients demonstrated atypical melanotic appearance. In 16 patients, extra-hepatic metastases were also developed. Conclusion: MR imaging could rule out hepatic metastasis in patients with malignant melanoma which showed intermediate findings on screened CECT, and could detect additional extra-hepatic metastases.

The reliable detection and quantification of these single-base DNA variants is technically challenging. Currently, a variety of techniques is applied, with no apparent "gold standard". Here we present a novel qPCR protocol that meets the conditions of extreme sensitivity and specificity that are required for detection and quantification of tumor DNA. By consecutive application of two polymerases, one of them designed for extreme base-specificity, the method reaches unprecedented sensitivity and specificity. Three qPCR assays were tested with spike-in experiments, specific for point mutations BRAF V600E, PTEN T167A and NRAS Q61L of melanoma cell lines. It was possible to detect down to one copy of tumor DNA per reaction (Poisson distribution, at a background of up to 200 000 wild type DNAs. To prove its clinical applicability, the method was successfully tested on a small cohort of BRAF V600E positive melanoma patients.

    Nivolumab, an anti-programmed cell death-1 protein monoclonal antibody, is effective for treating patients with late-stage non-small-cell lung cancer. Immune checkpoint inhibitors such as nivolumab induce various kinds of immune-related adverse events, including vitiligo. Vitiligo has been reported in patients with melanoma but not lung cancer. We describe a 75-year-old man with lung adenocarcinoma, stage 4 with pleural and pericardial effusion, that progressed after first-line chemotherapy. Subsequently, he was treated with nivolumab as second-line therapy. After 6days of administering nivolumab, he developed vitiligo suddenly on the trunk of his body. Except for vitiligo, his physical examination was normal, and treatment with nivolumab was well tolerated. Therefore, this treatment was continued without further development or expansion of vitiligo. A computed tomography scan showed a reduction in the size of the lung nodule and stabilization of the pleural and pericardial effusion. This is the first case of vitiligo associated with the use of nivolumab in a patient with lung adenocarcinoma. Copyright © 2017. Published by Elsevier B.V.

    Sentinel lymph node excision (SLNE) for the detection of regional nodal metastases and staging of malignant melanoma has resulted in some controversies in international discussions as it is a surgical intervention with potential morbidity. The present retrospective study seeks to clarify the reliability of preoperative ultrasonography (US) in direct comparison to the result of SLNE and seeks to identify potential advantages of preoperative ultrasound if performed in conjunction with lymphoscintigraphy in detecting malignant melanoma metastases in sentinel lymph node (SLN). We retrospectively analysed data from 221 patients with primary malignant melanoma with a Breslow index of ≥ 1.0 mm. Of the 221 patients, 77.4% (n = 171) had a negative SLN. In 50 patients (22.6%), the histopathological investigation of 71 excised lymph nodes resulted in a positive SLN. The US examination demonstrated a sensitivity of 13.6%, a specificity of 96.9%, a positive predictive value of 97.2% and a negative predictive value of 12.6%. SLNE alone shows a sensitivity of 94%, a specificity of 98.6%, a positive predictive value of 100% and a negative predictive value of 98.3%. Preoperative US in conjunction with dynamic lymphoscintigraphy, followed by SLNE, demonstrated a detecting ratio of 100% (n = 28) for micrometastases and 98.6% (n = 42/43) for macrometastases. In conclusion, this study confirms that preoperative US alone cannot replace the vital information obtained during dynamic lymphoscintigraphy. But preoperative US is an important component of the staging procedure in melanoma patients and has clear advantages when performed in conjunction with dynamic lymphoscintigraphy. Therefore, we recommend preoperative US before every SLNE. © 2011 The Authors. Journal of the European Academy of Dermatology and Venereology © 2011 European Academy of Dermatology and Venereology.

    The aim of the study was to evaluate if 18F-FDG-PET has the potential to detect complete responders to PD1-therapy in patients with unresectable metastasized melanoma two weeks after therapy initiation. Between September 2014 and May 2016, ten patients (four females; 65 ± 12 y) received a whole-body 18F-FDG-PET/MRI examination at three time points: Before therapy start (t{sub 0}, base-line), two weeks (t{sub 1}, study examination) and three months after treatment initiation (t{sub 2}, reference standard). Therapy response was assessed with PET response criteria in solid tumors (PERCIST). Time to progression and overall survival (OS) were obtained for all patients. Three patients with partial metabolic response in PET at t{sub 1} turned out to have complete response at t{sub 2}. No tumor relapse was observed in those patients so far (observation period: 265, 511 and 728 days, respectively). At t{sub 2}, progressive metabolic disease (PMD) was seen in six patients from whom four showed PMD and two showed stable metabolic disease (SMD) at t{sub 1}. OS in patients with PMD at t{sub 2} varied between 148 and 814 days. SMD at both t{sub 1} and t{sub 2} was seen in one patient, tumor progress was observed after 308 days. Our study indicates that whole-body 18F-FDG-PET might be able to reliably identify complete responders to PD1-therapy as early as two weeks after therapy initiation in stage IV melanoma patients. This might help to shorten therapy regimes and avoid unnecessary side effects in the future. (orig.)

    Genetically enhanced sensitivity to ultraviolet (UV) radiation may play an important role in the development of cutaneous malignant melanoma (CMM). This was studied in cultured fibroblasts of 26 CMM patients and controls by micronucleus (MN) test and sister chromatid exchange (SCE) after UV irradiation (375 J/m2). Sister chromatid exchange and MN formation were used as parameters to detect the UV-induced genotoxic damage in the individual cell strains. We found that the UV-induced level of MN was significantly increased in CMM patients (p = 0.0005), being most pronounced in the familial cases (p = 0.0001). Ultraviolet-induced SCE was also elevated in CMM patients (p = 0.001), but there was no difference between familial and nonfamilial cases. The present findings indicate that genetic predisposition contributes to the development of CMM in a subset of CMM patients and may be due to an enhanced susceptibility to UV light

    The X-linked inhibitor of apoptosis protein (XIAP) is the most potent of the inhibitor of apoptosis family of eight proteins. High levels of XIAP have been found in melanoma cell lines and are believed to play a role in therapeutic resistance in a number of malignancies. XIAP expression has not been investigated in clinically obtained melanoma tissue samples, nor have studies attempted to correlate XIAP expression with prognostic variables or clinical aggressiveness of melanomas. Sixty-seven patients with primary cutaneous malignant melanoma for whom clinical follow up was available were identified from the records of the Mount Sinai Hospital, comprising 37 thin melanomas (Breslow thickness 1.0 mm). Archival paraffin sections from primary lesions and corresponding metastases were stained with monoclonal anti-XIAP antibody using routine immunohistochemical methods. Six benign intradermal nevi and four in situ melanomas were XIAP negative. 9 of 37 thin melanomas (24%) were XIAP positive. In contrast, 21 of 30 (73%) thick melanomas were XIAP positive, including 3 of 4 ulcerated melanomas that were strongly positive. Over a follow-up period ranging from 6 months to 6 years, 23 melanomas metastasized (22 thick, 1 thin). In total, XIAP was immunohistochemically detected in 17 of 23 metastases (74%). Metastasis occurred in 1 of 9 XIAP-positive thin melanomas; 0 of 28 XIAP-negative thin melanomas; 17 of 22 XIAP-positive thick melanomas, and 5 of 8 XIAP-negative thick melanomas (63%). XIAP is immunohistochemically detectable nearly three times more frequently in thick compared with thin melanomas. These results suggest that XIAP elevation may be correlated with increasing melanoma thickness and tumor progression.

    Early detection is a key strategy for reducing the mortality and economic burden associated with melanoma. Dermoscopy is a non-invasive and cost-effective tool for melanoma diagnosis, which has been shown to be a reliable and sensitive method for detecting early-stage skin cancer and reducing the number of unnecessary excisions. Patients at high risk of developing melanoma require long-term surveillance. Use of digital dermoscopy follow-up of these patients has led to improved outcomes. Combined follow-up programmes using total-body photography and digital dermoscopy have led to further improvements in early diagnosis and diagnostic accuracy. Dermoscopy is now widely used by dermatologists, but the public health impact of this tool is yet to be evaluated. Despite the clear advantages of dermoscopy and digital follow-up meth-ods, dermoscopy training and access to digital dermoscopy among dermatologists and general practitioners needs to be improved.

    People with a melanoma diagnosis are at risk of recurrence, developing a new primary or experiencing disease progression. Previous studies have suggested that fear of a cancer recurrence is clinically relevant in this group of patients and, if not addressed, can lead to distress. Mindfulness-based interventions have been shown to alleviate symptoms of anxiety and depression among various groups of cancer patients. Online mindfulness-based interventions have the potential to reach people unable to attend face-to-face interventions due to limitations such as cancer-related illness, transportation or time constraints. This study aims to (1) examine whether individuals with a melanoma diagnosis are willing to participate and adhere to a 6-week online mindfulness-based intervention and (2) explore potential benefits of the program on fear of cancer recurrence, worries, rumination, perceived stress and trait mindfulness to inform the design of a clinical trial. This is a single-site randomised controlled trial of a feasibility study. Seventy-five participants with stage 2c or 3 melanoma will be recruited from a melanoma outpatient clinic and randomised (2:1) either to an online mindfulness-based program (intervention) or to usual care (control). The intervention is a 6-week program specifically developed for this study. It consists of videos describing the concept of mindfulness, short daily guided meditation practices (5-10 min), automated meditation reminders and instructions for applying mindfulness in daily life to enhance wellbeing. All participants will complete questionnaires at baseline and at 6-week post-randomisation. Participants in the control group will be given access to the online program at the end of the study. Primary outcomes are overall recruitment; retention; extent of questionnaire completion; and usability and acceptability of, and adherence to, the program. The secondary outcomes are fear of cancer recurrence, worries, rumination, perceived

    The identification of effective adjuvants is critical for tumor vaccine development. Towards this end, we examined whether the immunogenicity of a melanoma vaccine could be potentiated by DETOX, an adjuvant consisting of monophosphoryl lipid A (MPL) and purified mycobacterial cell-wall skeleton (CWS). Nineteen patients with resected stage III melanoma were immunized with a polyvalent melanoma antigen vaccine (40 micrograms) admixed with DETOX, q3 wks x 4. Seven patients received vaccine + low-dose DETOX (10 micrograms MPL + 100 micrograms CWS) and 12 received vaccine + high-dose DETOX (20 micrograms MPL + 200 micrograms CWS). A non-randomized control group of 35 patients was treated similarly with 40 micrograms vaccine + alum. One week after the fourth vaccine immunization, melanoma antibodies were increased over baseline in 7/7 (100%) patients treated with vaccine + low-dose DETOX, 8/12 (67%) patients treated with vaccine + high-dose DETOX, and in 4/19 (21%) of vaccine + alum patients. For the entire DETOX group, the antibody response rate was 15/19 (79%) compared 4/19 (21%) in the alum group (p or = 15 mm increase in DTH response over baseline) was induced in 50% of the entire DETOX group versus in 47% of the alum group. Median disease-free (DF) survival for the entire DETOX group was 17.8 months compared with 32.1 months in the alum group (p DETOX markedly potentiated antibody but had little effect on DTH responses to melanoma vaccine immunization. It did not appear to improve disease-free survival in comparison to alum in this non-randomized study.

    Pulsed neodymium laser radiation was used for the treatment of 79 patients with cutaneous melanomas and 19 patients with melanoma metastases to the skin. The patients were followed up from 3 months up to 8 years. During this period local recurrences were detected in 2 cases. Out of 70 patients with cutaneous melanomas, who by the start of the treatment had no metastases in the regional lymph nodes or distant organs, metastases developed in 15 patients (21.4%). There are all reasons to consider pulsed laser radiation an effective means of treatment of some forms of skin melanoma.

    The authors present a case of a psychotic female patient who is a former graduate of a locally prestigious medical school and has subsequently been diagnosed with schizophrenia. The patient entered treatment in an outpatient clinic following discharge from her 11th hospitalization. This hospitalization was initiated after the patient's physician friend had called the police and notified them that the patient was significantly disorganized to warrant further evaluation. Treatment was characterized by significant transference and counter-transference reactions amongst her clinicians - both treatment-promoting and treatment-interfering - based on her status as a physician. The problem of insight was a significant hurdle in the treatment of the patient as her medical knowledge of mental illness was substantially greater than her insight into her own mental illness. Throughout treatment, a number of medical-legal and ethical issues arose. Initially, the question was raised as to the legality of the actions by the patient's friend-having made a clinical assessment without having a clinical role in the patient's care. As the patient's clinical status improved and she sought to re-enter the medical field as a resident, new medical legal issues surfaced. What were the roles of the patient's treaters in maintaining confidentiality and simultaneously ensuring the safety of patients that the psychotic physician might care for? This case highlights the universality of psychiatric vulnerability. Insight in psychosis as well as the transference and counter-transference issues involved in caring for a psychotic physician are discussed. Additionally, a thorough medical-legal discussion addresses the various complexities of caring for a psychotic physician. Copyright © 2012 Elsevier B.V. All rights reserved.

    Introduction. Melanoma is now considered an epidemic around the world. Its high lethality, constitutes a serious problem despite the continuous pharmacological and technological advances. NeuGcGM3/VSSP is a vaccine formulation containing ganglioside NeuGcGM3 incorporated in the acting of Neisseria meningitidis. It may be a choice therapeutic given this ganglioside in primary melanoma expression and immunogenicity and safety demonstrated by this vaccine in advanced breast cancer. This study evaluated the safety, immunogenicity and the anti-tumor response in patients with advanced melanoma to manage it via IM or SC. Material and methods: The expression of ganglioside in primary melanomas and its metastases was identified by immunohistochemical methods with the AcM 14F7 (anti-NGCGM3). 2 clinical trials Phase Ib/IIa escalation of doses with NeuGcGM3 /VSSP were conducted in patients with melanoma Advanced IM and SC routes. Safety and anti-tumour response were evaluated with the CTC and RECIST criteria. The statistical analysis was performed with the SPSS statistical package. Results: NeuGcGM3 is expressed in primary tumors and the studied lymph nodes metastases. NeuGcGM3/VSSP was safely managed by the SC and IM, roads without limiting toxicity. Immunogenic with IgM and IgG isotype antibody response resulted in 75% patients. There was anti-tumoral response in 38.5% with increase in median SV mainly associated with anti-tumor response. The appearance of vitiligo and the response of antibodies against other not present in the vaccine formulation gangliosides may be considered a manifestation of immune restoration. Conclusions. NeuGcGM3/VSSP managed IM and SC in patients with advanced melanoma was safe, immunogenic and antitumor activity associated with overall survival advantage. (author)

    Full Text Available Abstract Background Malignant melanoma occurs infrequently in Taiwan. Once it has progressed into osseous metastases, the prognosis is poor. There are no reported clinical experiences of surgical management in this area. Methods To improve our understanding of the rare clinical experiences, we retrospectively investigated clinical characteristics, radiological findings, treatment modalities, survival outcomes and prognoses of 11 Taiwanese patients with osseous metastasis of melanoma treated surgically at two national medical centers, National Taiwan University Hospital and National Cheng Kung University Hospital from January 1983 to December 2006. Results Six patients suffered from acral-lentiginous melanoma. Nine patients sustained multiple osseous metastases and most lesions were osteolytic. Nine patients also had sustained metastases to other organs including liver, lungs, lymph nodes, brain and spleen. Second malignancies including lung cancer, thyroid papillary carcinoma, renal cell carcinoma and cervical cancer co-existed in four patients. The interval from the initial diagnosis of melanoma to the clinical detection of osseous metastases varied from 0–37.8 months (mean 9.75 months. Metastatic melanoma was invariably fatal; the mean survival time from bone metastases to death was 5.67 months. Conclusion Due to the high morbidity and poor survival of Taiwanese patients with osseous metastases of melanoma, surgical treatment should be directed towards pain relief and the prevention of skeletal debilitation in order to maintain their quality of life.

    1980-01-01

    Six hundred and thirteen consecutive patients with Hodgkin's disease (HD), with a follow-up of two to ten years, were reviewed with the aim of establishing the type and frequency of second malignancies. Acute non-lymphoid leukemia developed in 2 of 152 patients treated by chemotherapy (CHT), and in 5 of 344 patients treated by CHT and radiotherapy (RT). Leukemia developed 12 to 83 months after diagnosis of HD, was always preceded by a preleukemic phase (3 to 25 months), and was always fatal (after 1 to 12 months). The karyotype of leukemic cells was studied in 4 of 7 patients and was always abnormal. Solid tumors developed in 1 of 152 patients treated by CHT, and in 4 of 344 patients treated by CHT and RT. The tumors appeared 10 to 63 months after diagnosis of HD and killed all 5 patients after 10 to 16 months. For patients treated by CHT, the actuarial frequency of leukemia and other tumors seven years after diagnosis of HD was 2.0% and 1.26%, respectively. For patients treated by CHT and RT, the figures were 2.04% and 2.26%, respectively. Second malignancies were not recorded among 117 patients treated by RT alone. These data are consistent with a relationship of acute leukemia to therapy for HD

  6. Brain tumors in patients primarly treated psychiatrically

    2011-01-01

    Full Text Available Introduction. Psychiatric symptoms are not rare manifestations of brain tumors. Brain tumors presented by symptoms of raised intracranial pressure, focal neurological signs, or convulsions are usually first seen by the neurologist or less frequently by the neurosurgeon in routine diagnostic procedures. On the other hand, when psychiatric symptoms are the first manifestation in “neurologically silent” brain tumors, the patients are sent to the psychiatrist for the treatment of psychiatric symptoms and brain tumors are left misdiagnosed for a long period of time. Case Report. We presented three patients with the diagnosed brain tumor where psychiatrist had been the first specialist to be consulted. In all three cases neurological examination was generally unremarkable with no focal signs or features of raised intracranial pressure. CT scan demonstrated right insular tumor in a female patient with obsessive-compulsive disorder (OCD; right parietal temporal tumor in a patient with delusions and depression and left frontal tumor in a patient with history of alcohol dependency. Conclusion. Psychiatric symptoms/disorders in patients with brain tumors are not specific enough and can have the same clinical presentation as the genuine psychiatric disorder. Therefore, we emphasize the consideration of neuroimaging in patients with abrupt beginning of psychiatric symptoms, in those with a change in mental status, or when headaches suddenly appear or in cases of treatment resistant psychiatric disorders regardless the lack of neurological symptoms.

  10. How I treat CLL patients with ibrutinib.

    Brown, Jennifer R

    2018-01-25

    Ibrutinib is a transformative therapy for high-risk and relapsed refractory chronic lymphocytic leukemia (CLL) patients. In clinical trials in relatively healthy younger patients, ibrutinib has been well tolerated. As its use has become more widespread in the community, however, its full adverse event profile has emerged and proven more challenging than was initially anticipated. Reports of community-based use have estimated discontinuation rates as high as 40% in the first year of therapy. This article therefore reviews my approach to the evaluation and management of a CLL patient starting on ibrutinib, with the goal of minimizing and managing toxicity to maintain patients on ibrutinib. Key topics discussed include bleeding risk; cardiac complications, particularly atrial fibrillation; drug interactions; and infections. © 2018 by The American Society of Hematology.

    This paper looks at systems of gender within the context of analysis. It explores the unique challenges of individuation faced by transsexual, transgender, gender queer, gender non-conforming, cross-dressing and intersex patients. To receive patients generously we need to learn how a binary culture produces profound and chronic trauma. These patients wrestle with being who they are whilst simultaneously receiving negative projections and feeling invisible. While often presenting with the struggles of gender conforming individuals, understanding the specifically gendered aspect of their identity is imperative. An analyst's unconscious bias may lead to iatrogenic shaming. The author argues that rigorous, humble inquiry into the analyst's transphobia can be transformative for patient, analyst, and the work itself. Analysis may, then, provide gender-variant patients with their first remembered and numinous experience of authentic connection to self. Conjuring the image of a hinge, securely placed in the neutral region of a third space, creates a transpositive analytic temenos. Invoking the spirit of the Trickster in the construction of this matrix supports the full inclusion of gender-variant patients. Nuanced attunement scaffolds mirroring and the possibility of play. Being mindful that gender is sturdy and delicate as well as mercurial and defined enriches the analyst's listening. © 2017, The Society of Analytical Psychology.

    Patients with metastatic melanoma have a poor prognosis; the results of chemotherapy remain unsatisfactory. Ipilimumab, an anticytotoxic T lymphocyte-associated antigen-4 antibody, has shown promising results in several clinical trials. In this report, advanced melanoma patients receiving ipilimumab were scored according to novel immune-related response criteria (irRC) in an attempt to capture additional response patterns and to avoid premature treatment cessation. Thirty-six heavily pretreated metastatic melanoma patients recieved ipilimumab within five international clinical trials at our Institution from May 2006 to August 2008. Disease progression was defined as an increase in tumor burden by at least 25% compared with the nadir, irrespective of any initial increase in baseline lesions or the appearance of new lesions. We report unusually long-lasting responses in patients treated with ipilimumab 10 mg/kg. An overall response was observed in six out of 30 patients (20%), a complete response in three (10%), and disease control in 11 (37%), which seemed to be of a long duration (median of 16 months; complete response 36+, 34+, and 41+ months). All irRC patterns seemed to be strongly associated with an improvement in overall survival. Interestingly, we found a correlation between the presence of a grade 3/4 immune-related adverse event and responses, time to progression, and overall survival. Ipilimumab therapy resulted in clinically meaningful responses in advanced melanoma patients, supporting the need for further irRC validation.

    In this paper we develop the hypothesis that a significant fraction of patients with advanced melanoma can be successfully treated with immunotherapy. Reversal of antigen-specific immune suppression to melanoma polypeptide antigens is an essential, first step. We postulate the key regulation of CTL responses resides within the CD4+ T-lymphocytes and macrophage/dendritic cells. There is a pluri-potential cell within this regulatory arm that functions either as a Th1 cell or as a suppressor T-cell, Ths, depending on how antigen is presented. We have shown that poliovirus 1 Sabin will lyse human melanoma cells in tissue culture, and a special "vaccine" prepared from this lysis actively stimulates Ths cell function. The Ths arm of the regulatory system can be down-regulated with cyclophosphamide given 24 hours after the vaccine. The capacity to generate a CTL response is retained. The summary conclusion is that a phase 1 clinical trial in advanced melanoma using the special viral-tumor-lysate followed by cyclophosphamide, plus expanded autologous dendritic cells sensitized with the polypeptide epitopes captained in the viral-lysate will produce beneficial results.

    PurposeTo evaluate the outcome of patients with melanoma liver metastasis treated with stereotactic radiofrequency ablation (SRFA).Material and MethodFollowing IRB approval, a retrospective evaluation of the treatment of 20 patients with 75 melanoma liver metastases was performed.ResultsA median number of 2 lesions (range 1–14) per patient with a median size of 1.7 cm (range 0.5–14.5 cm) were treated. 67 lesions were <3 cm (89.3 %) and 8 lesions were >3 cm (10.7 %). Per patient a median of 1 ablation session was performed (range: 1–4) totaling 34 sessions. There were no procedure-related deaths and all major complications (n = 3) could be easily treated by pleural drainages. The primary and secondary success rates were 89.3 and 93.3 %, respectively. The overall local recurrence rate was 13.3 %. Four of ten local recurrences were re-treated successfully by SRFA. During follow-up, 9/20 patients developed extrahepatic metastatic disease and 10/20 had liver recurrence at any location. The median OS from the date of SRFA was 19.3 months, with an OS of 64, 41, and 17 % at 1, 3, and 5 years, with no significant difference for patients with cutaneous and ocular melanoma. The median DFS after SRFA for all 20 patients was 9.5 months, with 37, 9, and 0 % at 1, 3, and 5 years.ConclusionsDue to the high local curative potential and the promising long-term survival rates associated with minimal morbidity and mortality, radiofrequency ablation seems to be an attractive alternative to resection in patients with melanoma liver metastases.

    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

    Influential views on how to protect patient autonomy in clinical care have been greatly shaped by rational and deliberative models of decision-making. Our aim was to understand how the general principle of respecting autonomy can be reconciled with the local reality of obtaining consent in a clinical situation that precludes extended deliberation. We interviewed 22 patients with intraocular melanoma who had been offered cytogenetic tumour typing to indicate whether the tumour was likely to shorten life considerably. They were interviewed before and/or up to 36 months after receiving cytogenetic results. Patients described their decision-making about the test and how they anticipated and used the results. Their accounts were analysed qualitatively, using inconsistencies at a descriptive level to guide interpretative analysis. Patients did not see a decision to be made. For those who accepted testing, their choice reflected trust of what the clinicians offered them. Patients anticipated that a good prognosis would be reassuring, but this response was not evident. Although they anticipated that a poor prognosis would enable end-of-life planning, adverse results were interpreted hopefully. In general, the meaning of the test for patients was not separable from ongoing care. Models of decision-making and associated consent procedures that emphasize patients' active consideration of isolated decision-making opportunities are invalid for clinical situations such as this. Hence, responsibility for ensuring that a procedure protects patients' interests rests with practitioners who offer it and cannot be delegated to patients. © 2010 Blackwell Publishing Ltd.

    Malignant melanoma is the 6th most commonly diagnosed cancer with increasing incidence in the United States. It is estimated that 54,200 cases of malignant melanoma will be newly diagnosed and 7,600 cases of death will occur in the United States in the year 2003 (1). At the present time, more than 1.3% of Americans will develop malignant melanoma during their lifetime (2). The average survival for patients with metastatic melanoma is about 6-9 months (3). Moreover, metastatic melanoma deposits are resistant to conventional chemotherapy and external beam radiation therapy (3). Systematic chemotherapy is the primary therapeutic approach to treat patients with metastatic melanoma. Dacarbazine is the only single chemotherapy agent approved by FDA for metastatic melanoma treatment (5). However, the response rate to Dacarbazine is only approximately 20% (6). Therefore, there is a great need to develop novel treatment approaches for metastatic melanoma. The global goal of this research program is the rational design, characterization and validation of melanoma imaging and therapeutic radiopharmaceuticals. Significant progress has been made in the design and characterization of metal-cyclized radiolabeled alpha-melanocyte stimulating hormone peptides. Therapy studies with {sup 188}Re-CCMSH demonstrated the therapeutic efficacy of the receptor-targeted treatment in murine and human melanoma bearing mice (previous progress report). Dosimetry calculations, based on biodistribution data, indicated that a significant dose was delivered to the tumor. However, {sup 188}Re is a very energetic beta-particle emitter. The longer-range beta-particles theoretically would be better for larger tumors. In the treatment of melanoma, the larger primary tumor is usually surgically removed leaving metastatic disease as the focus of targeted radiotherapy. Isotopes with lower beta-energies and/or shorter particle lengths should be better suited for targeting metastases. The {sup 177}Lu

    Uveal melanoma is a rare melanoma variant with no effective therapies once metastases develop. Although durable cancer regression can be achieved in metastatic cutaneous melanoma with immunotherapies that augment naturally existing antitumor T-cell responses, the role of these treatments for metastatic uveal melanoma remains unclear. We sought to define the relative immunogenicity of these two melanoma variants and determine whether endogenous antitumor immune responses exist against uveal melanoma. We surgically procured liver metastases from uveal melanoma (n = 16) and cutaneous melanoma (n = 35) patients and compared the attributes of their respective tumor cell populations and their infiltrating T cells (TIL) using clinical radiology, histopathology, immune assays, and whole-exomic sequencing. Despite having common melanocytic lineage, uveal melanoma and cutaneous melanoma metastases differed in their melanin content, tumor differentiation antigen expression, and somatic mutational profile. Immunologic analysis of TIL cultures expanded from these divergent forms of melanoma revealed cutaneous melanoma TIL were predominantly composed of CD8(+) T cells, whereas uveal melanoma TIL were CD4(+) dominant. Reactivity against autologous tumor was significantly greater in cutaneous melanoma TIL compared with uveal melanoma TIL. However, we identified TIL from a subset of uveal melanoma patients which had robust antitumor reactivity comparable in magnitude with cutaneous melanoma TIL. Interestingly, the absence of melanin pigmentation in the parental tumor strongly correlated with the generation of highly reactive uveal melanoma TIL. The discovery of this immunogenic group of uveal melanoma metastases should prompt clinical efforts to determine whether patients who harbor these unique tumors can benefit from immunotherapies that exploit endogenous antitumor T-cell populations.

    Purpose: To ascertain predictors of distant brain failure (DBF) in patients treated initially with stereotactic radiosurgery alone for newly diagnosed brain metastases. We hypothesize that these factors may be used to group patients according to risk of DBF. Methods and Materials: We retrospectively analyzed 100 patients with newly diagnosed brain metastases treated from 2003 to 2005 at our Gamma Knife radiosurgery facility. The primary endpoint was DBF. Potential predictors included number of metastases, tumor volume, histologic characteristics, extracranial disease, and use of temozolomide. Results: One-year actuarial risk of DBF was 61% for all patients. Significant predictors of DBF included more than three metastases (hazard ratio, 3.30; p = 0.004), stable or poorly controlled extracranial disease (hazard ratio, 2.16; p = 0.04), and melanoma histologic characteristics (hazard ratio, 2.14; p = 0.02). These were confirmed in multivariate analysis. Those with three or fewer metastases, no extracranial disease, and nonmelanoma histologic characteristics (N = 18) had a median time to DBF of 89 weeks vs. 33 weeks for all others. One-year actuarial freedom from DBF for this group was 83% vs. 26% for all others. Conclusions: Independent significant predictors of DBF in our series included number of metastases (more than three), present or uncontrolled extracranial disease, and melanoma histologic characteristics. These factors were combined to identify a lower risk subgroup with significantly longer time to DBF. These patients may be candidates for initial localized treatment, reserving whole-brain radiation therapy for salvage. Patients in the higher risk group may be candidates for initial whole-brain radiation therapy or should be considered for clinical trials

  5. New Safety Margins for Melanoma Surgery: Nice Possibility for Drinking of "Just That Cup of Coffee"?

    The American Joint Committee on Cancer (AJCC's) skin melanoma surgical treatment recommendations from 2011 are characterised by a prima facie "freedom of choice" regarding how extensive should be the excisions for melanomas with tumour thickness up to 2 mm and melanoma in situ. It is unclear why the recommended surgical security margins vary between 0.5 and 1 cm for melanoma in situ, whereas for melanomas with a tumour thickness of up to 1.99 mm, the range of variation is also between 1 and 2 cm, without specifying when the surgical field should be broader and, narrower, accordingly. This "uncertainty or lack of intent" of the guilders often leads to the same surgical approach to melanomas at different stages, or to a different approach in cases of melanomas at the same stage, in contrast. Therefore, this should be defined as wrong, logically. We present 3 patients with cutaneous melanomas, treated with similar fields of surgical security. Current issues, generated within the framework of melanoma's surgery guided by the recommendations of the AJCC are also discussed. A new surgical approach in patients with melanoma is recommended, discussed for the first time in world literature. We hypothesize that the introduction of a certain recommendations for a 2 cm surgical field in all directions during the initial excision, combined with the parallel performance of a sentinel lymph node biopsy, will lead in fact to several important advantages: 1) avoiding of the secondary excision in at least 70% - 90% of the patients (depending on the tumor thickness), 2) minimizing the risk of lymphatic effusion change and misinterpretation of the sentinel lymph node biopsy's results in patients with secondary excision; 3) optimization of the surgical team's work; 4) minimizing the possibility of unprepared/uninformed personnel to take part in decisions for treating a specific disease such as skin melanoma, 4) facilitating the appropriate patients' group selection at the appropriate

The transfusion guidelines up to 2006 recommended that resuscitation of massive hemorrhage should occur in successive steps using crystalloids, colloids and red blood cells (RBC) in the early phase, and plasma and platelets...... in the late phase. With the introduction of the cell-based model of hemostasis in the mid 1990ties, our understanding of the hemostatic process and of coagulopathy has improved. This has contributed to a change in resuscitation strategy and transfusion therapy of massive hemorrhage along with an acceptance...... outcome, although final evidence on outcome from randomized controlled trials are lacking.

    The benefit of a sentinel lymph node (SLN) biopsy and adjuvant therapy for patients with thick (>4 mm) melanoma has not been well studied in the Asian population. We examined the benefit of an SLN biopsy and adjuvant therapy on prognosis in Japanese patients with thick melanoma. A review of the melanoma database collected from 26 institutions in Japan identified 291 patients with thick melanoma between 2005 and 2010. Univariate and multivariate analyses were performed to evaluate the factors predictive of the overall survival (OS) and the disease-free survival (DFS). Of the 242 patients with thick melanoma who underwent an SLN biopsy, the results for 96 (40%) were positive. On multivariate analysis, increased Breslow thickness (relative risk, 1.11; 95% confidence interval, 1.05-1.17; P=0.0002) and SLN metastasis (2.14; 1.04-4.43; P=0.040) were associated with a poor OS. Increased Breslow thickness (1.11; 1.04-1.18; P =0.0018), ulceration (3.11; 1.25-7.72; P=0.014), satellitosis (3.89; 1.62-9.31; P=0.0023), and SLN metastasis (2.24; 1.16-4.36; P=0.017) were associated with DFS. Adjuvant chemotherapy had no impact on either OS or DFS. Adjuvant use of a monthly dermal injection of interferon-β (IFN-β) was associated with a improvement in both OS (0.34; 0.17-0.67; P=0.0022) and DFS (0.42; 0.20-0.86; P=0.018). An SLN biopsy provided useful prognostic information and the adjuvant use of IFN-β improved both OS and DFS in Japanese patients with thick melanoma. These results were consistent with those of previous studies carried out on a white population. Therefore, we suggest that an SLN biopsy and adjuvant IFN should be considered for patients with thick melanoma irrespective of the Breslow thickness or ethnicity.

    Malignant melanoma is a high-risk skin cancer that, in potential transplant recipients, is considered a substantial contraindication to solid organ transplantation due to significant risk of recurrence with immunosuppression. Current guidelines stipulate waiting between 3 and 10 years after melanoma diagnosis. However, in young patients with end-stage organ failure and malignant melanoma, complex ethical and moral issues arise. Assessment of the true risk associated with transplantation in these patients is difficult due to lack of prospective data, but an autonomous patient can make a decision that clinicians may perceive to be high risk. The national and worldwide shortage of available organs also has to be incorporated into the decision to maximize the net benefit and minimize the risk of graft failure and mortality. The incidence of malignant melanoma worldwide is increasing faster than that of any other cancer and continues to pose ethically challenging decisions for transplant specialists evaluating recipients for solid organ transplantation. © 2016 British Association of Dermatologists.

    The aim of this study was to investigate the impact of noise-optimized virtual monoenergetic imaging (VMI+) reconstructions on quantitative and qualitative image parameters in patients with cutaneous malignant melanoma at thoracoabdominal dual-energy computed tomography (DECT). Seventy-six patients (48 men; 66.6±13.8years) with metastatic cutaneous malignant melanoma underwent DECT of the thorax and abdomen. Images were post-processed with standard linear blending (M_0.6), traditional virtual monoenergetic (VMI), and VMI+ technique. VMI and VMI+ images were reconstructed in 10-keV intervals from 40 to 100keV. Attenuation measurements were performed in cutaneous melanoma lesions, as well as in regional lymph node, subcutaneous and in-transit metastases to calculate objective signal-to-noise (SNR) and contrast-to-noise (CNR) ratios. Five-point scales were used to evaluate overall image quality and lesion delineation by three radiologists with different levels of experience. Objective indices SNR and CNR were highest at 40-keV VMI+ series (5.6±2.6 and 12.4±3.4), significantly superior to all other reconstructions (all Ptraditional VMI in patients with cutaneous malignant melanoma at thoracoabdominal DECT.

    The aim of the study was to compare the effect of carboplatin chemotherapy on the survival of canine patients diagnosed with malignant melanoma after loco-regional control or as a sole therapy. A retrospective study of 63 dogs with oral, digital or cutaneous malignant melanoma treated with surgery and/or chemotherapy was undertaken. Dogs were grouped based on the anatomical site of melanoma development. For oral melanoma, dogs were subclassified into two groups: loco-regional control and gross disease. All patients in the digital and cutaneous groups had achieved loco-regional control with surgery. Comparisons between survival data for each group at each anatomical site were then made. Within the loco-regional control groups survival time was compared between those treated with and without chemotherapy post surgery. For the oral melanoma patients with gross disease survival was compared between those treated with chemotherapy and palliative therapy. The toxicity of carboplatin chemotherapy was evaluated overall. The overall median survival times for patients with oral, digital and cutaneous melanoma were 389, 1,350 days and not reached (with a median follow-up of 776 days) respectively. Median survival time was defined as "not reached" when less than 50% of the subjects died of the disease at the end of the follow-up period, or at the time they were lost to follow-up. The addition of chemotherapy to surgery did not confer a survival benefit in the loco-regional control setting when assessing survival for each anatomical site. For oral melanoma patients with gross disease there was no difference between survival of patients treated with chemotherapy and palliative intent therapy. There was however an improvement in survival in the three dogs that responded to chemotherapy (978 days; p=0.039) compared to the eight non-responders (147 days). On univariate and multivariate analysis, anatomic location was the only variable that was significantly related to survival (p=0

    Scintigraphic identification of the sentinel lymph node is achievable in nearly all patients with malignant melanoma. However, in a very small number of cases the sentinel node fails to be detected, and sometimes recurrence appears during follow-up in patients who had previously tested negative for metastatic disease. The purpose of this study was to review our experience in order to isolate the reasons for erroneous sentinel lymph node identification. The evaluation involved 435 consecutive malignant melanoma patients with AJCC stages I and II (clinically negative nodes) and Breslow thickness >0.76 mm. Lymphoscintigraphy was performed the day before surgery by intradermal administration of technetium-99m labelled nanocolloid. Dynamic and static images were obtained. The sentinel node was intraoperatively identified with the aid of patent blue dye and a hand-held gamma probe. After removal, routine histopathological examination with haematoxylin-eosin (H-E) and immunohistochemistry with S 100 and HMB45 (IHC) were performed. In those patients who developed regional recurrences during follow-up, sentinel nodes were further evaluated by reverse transcriptase-polymerase chain reaction (RT-PCR). Lymphoscintigraphy visualised at least one sentinel node in 434 out of 435 patients (99.8%). Uptake in in-transit sentinel lymph nodes was observed in 32 patients (7.4%). During surgery, localisation and removal of sentinel nodes was successful in 430/435 patients (98.8%). A total of 790 sentinel lymph nodes were harvested, with a mean of 1.8 per patient. Routine histopathological examination with H-E or IHC revealed metastatic disease in 72 patients (16.8%). During a mean follow-up of 26 months, seven of those patients with a negative sentinel node developed regional lymph node metastases. In five of them RT-PCR was positive for micrometastases within the sentinel node. In conclusion, erroneous sentinel lymph node identification can be due to changes in the surgical team

    Full Text Available BACKGROUND: A direct comparison of prognosis between patients with regional lymph node metastases (LNM detected synchronously with the primary melanoma (primary LNM, patients who developed their first LNM subsequently (secondary LNM and those with initial LNM in melanoma with unknown primary site (MUP is missing thus far. PATIENTS AND METHODS: Survival of 498 patients was calculated from the time point of the first macroscopic LNM using Kaplan Meier and multivariate Cox hazard regression analysis. RESULTS: Patients with secondary LNM (HR = 0.67; p = 0.009 and those with initial LNM in MUP (HR = 0.45; p = 0.008 had a better prognosis compared to patients with primary LNM (median survival time 52 and 65 vs. 24 months, respectively. A high number of involved nodes, the presence of in-transit/satellite metastases and male gender had an additional independent unfavourable effect. CONCLUSIONS: Survival of patients with LNM in MUP and with secondary LNM is similar and considerably more favourable compared to those with primary LNM. This difference needs to be considered during patient counselling and for stratification purposes in clinical trials. The assumption of an immune privilege of patients with MUP which is responsible for rejection of the primary melanoma, and results in a favourable prognosis is not supported by our data.

    Chronic inflammatory conditions, such as psoriasis, may pose an increased risk of cancer due to impaired immunosurveillance resulting from chronic inflammation and immunosuppressive medications. To compare the risk of non-melanoma skin cancer (NMSC) in a retrospective cohort of 72,739 psoriasis patients and 25,956 non-dermatological patients. A record linkage was performed for data on hospitalizations, and the occurrence of NMSC was compared by computing the relative risk (RR) and modelled using multiple logistic regression. Overall, the occurrence of NMSC was 9.6‰ (95% CI: 8.9-10.3‰) in psoriasis patients and 19.6‰ (95% CI: 18.0-21.4‰) in non-dermatological patients (RR = 0.49; 95% CI: 0.44-0.55). The simultaneous adjustment for gender, age, and phototherapy yielded a RR of 0.84 (95% CI: 0.75-0.95). With regards to phototherapy, the occurrence of NMSC was significantly higher among psoriasis patients who underwent phototherapy relative to those who did not (27.0‰ vs. 9.3‰). In this large retrospective study, we found that patients with psoriasis had a 16% lower probability of having NMSC when compared to a group of non-dermatological patients. Further studies, preferably with a prospective longitudinal design to collect more precise data, are needed to corroborate our findings.

    Full Text Available Abstract 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

An early stage melanoma can be surgically removed, with a survival rate of 99%. However, metastasized melanoma is difficult to cure. The 5-year survival rates for patients with metastasized melanoma are still below 20%. Metastasized melanoma is currently treated by chemotherapy, targeted therapy, immunotherapy and radiotherapy. The outcome of most of the current therapies is far from optimistic. Although melanoma patients with a mutation in the oncogene v-Raf murine sarcoma viral oncogene homolog B1 (BRAF have an initially higher positive response rate to targeted therapy, the majority develop acquired drug resistance after 6 months of the therapy. To increase treatment efficacy, early diagnosis, more potent pharmacological agents, and more effective delivery systems are urgently needed. Nanotechnology has been extensively studied for melanoma treatment and diagnosis, to decrease drug resistance, increase therapeutic efficacy, and reduce side effects. In this review, we summarize the recent progress on the development of various nanoparticles for melanoma treatment and diagnosis. Several common nanoparticles, including liposome, polymersomes, dendrimers, carbon-based nanoparticles, and human albumin, have been used to deliver chemotherapeutic agents, and small interfering ribonucleic acids (siRNAs against signaling molecules have also been tested for the treatment of melanoma.

    Immunization with autologous dendritic cells (DCs) loaded with a heat shock-conditioned allogeneic melanoma cell lysate caused lysate-specific delayed type hypersensitivity (DTH) reactions in a number of patients. These responses correlated with a threefold prolonged long-term survival of DTH(+) with respect to DTH(-) unresponsive patients. Herein, we investigated whether the immunological reactions associated with prolonged survival were related to dissimilar cellular and cytokine responses in blood. Healthy donors and melanoma patient's lymphocytes obtained from blood before and after vaccinations and from DTH biopsies were analyzed for T cell population distribution and cytokine release. Peripheral blood lymphocytes from melanoma patients have an increased proportion of Th3 (CD4(+) TGF-β(+)) regulatory T lymphocytes compared with healthy donors. Notably, DTH(+) patients showed a threefold reduction of Th3 cells compared with DTH(-) patients after DCs vaccine treatment. Furthermore, DCs vaccination resulted in a threefold augment of the proportion of IFN-γ releasing Th1 cells and in a twofold increase of the IL-17-producing Th17 population in DTH(+) with respect to DTH(-) patients. Increased Th1 and Th17 cell populations in both blood and DTH-derived tissues suggest that these profiles may be related to a more effective anti-melanoma response. Our results indicate that increased proinflammatory cytokine profiles are related to detectable immunological responses in vivo (DTH) and to prolonged patient survival. Our study contributes to the understanding of immunological responses produced by DCs vaccines and to the identification of follow-up markers for patient outcome that may allow a closer individual monitoring of patients.

    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.

    Primary melanomas of the vulva and vagina are rare. As a result, it has been difficult to develop evidence-based guidelines for their management. By analyzing a large series of patients with vulval and vaginal melanomas, this study sought to document the most common presenting features, identify clinical and pathologic predictors of outcome, and provide management guidelines. A clinicopathologic analysis of 85 patients with primary melanomas of the vulva or vagina diagnosed and treated at Melanoma Institute Australia and associated units in Sydney, Australia, between 1960 and 2011 was performed. Predictors of disease-free and melanoma-specific survival (MSS) were determined. Patients with American Joint Committee on Cancer (AJCC) stage 0-II had a significantly better MSS (5Y MSS = 63.6 %, n = 59) compared with those with stage III disease (5Y MSS = 0 %, n = 12, p < 0.001). Tumor thickness, ulceration status, and pathologic clearance margin were significant predictors of MSS. Disease-free survival was predicted by these factors and additionally by tumor mitotic rate. The results of this study provide evidence to support the appropriateness of utilizing the AJCC (7th edition) cutaneous melanoma staging system for vulval and vaginal melanomas. Detection and removal of these melanomas at an early stage with pathologically confirmed clear margins confers the best chance of cure.

    Nivolumab, a fully human IgG4 PD-1 immune checkpoint inhibitor antibody, can result in durable responses in patients with melanoma who have progressed after ipilimumab and BRAF inhibitors. We assessed the efficacy and safety of nivolumab compared with investigator's choice of chemotherapy (ICC) as a second-line or later-line treatment in patients with advanced melanoma. In this randomised, controlled, open-label, phase 3 trial, we recruited patients at 90 sites in 14 countries. Eligible patients were 18 years or older, had unresectable or metastatic melanoma, and progressed after ipilimumab, or ipilimumab and a BRAF inhibitor if they were BRAF(V 600) mutation-positive. Participating investigators randomly assigned (with an interactive voice response system) patients 2:1 to receive an intravenous infusion of nivolumab 3 mg/kg every 2 weeks or ICC (dacarbazine 1000 mg/m(2) every 3 weeks or paclitaxel 175 mg/m(2) combined with carboplatin area under the curve 6 every 3 weeks) until progression or unacceptable toxic effects. We stratified randomisation by BRAF mutation status, tumour expression of PD-L1, and previous best overall response to ipilimumab. We used permuted blocks (block size of six) within each stratum. Primary endpoints were the proportion of patients who had an objective response and overall survival. Treatment was given open-label, but those doing tumour assessments were masked to treatment assignment. We assessed objective responses per-protocol after 120 patients had been treated with nivolumab and had a minimum follow-up of 24 weeks, and safety in all patients who had had at least one dose of treatment. The trial is closed and this is the first interim analysis, reporting the objective response primary endpoint. This study is registered with ClinicalTrials.gov, number NCT01721746. Between Dec 21, 2012, and Jan 10, 2014, we screened 631 patients, randomly allocating 272 patients to nivolumab and 133 to ICC. Confirmed objective responses were reported

    Nivolumab, a new immune checkpoint inhibitor, binds to programmed cell death-protein 1 receptors on T cell, blockades binding of its ligands, and augments the immunologic reaction against tumor cells. Augmented immune response, however, may lead to immune-related adverse events. Herein we describe a rare case of bilateral anterior uveitis induced by nivolumab treatment for metastatic melanoma. A 54-year-old woman presented with mild conjunctival redness and blurred vision two months after initiating nivolumab treatment. Ophthalmological examination revealed bilateral non-granulomatous anterior uveitis. The flare values in the anterior chamber were monitored as an objective inflammatory index during nivolumab therapy and clinical time course was reported in this paper.

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. Keywords: melanoma, pediatric, adolescent, childhood

    Tumor-control probability (TCP) was analyzed in a series of 121 patients having 239 histologically proven recurrent or metastatic malignant melanomas. These were treated with fractionated radiotherapy with various doses per fraction, total doses, and overall times. Cutaneous lesions (127,53%) were treated with electron beams, and more deeply seated tumors (112,47%) with 60 Co or 4-8 MV X-rays. The fraction size was highly variable, and this permitted determination of the α/β ration in the multifraction linearquadratic model, which was estimated at 0.57 Gy with 95% confidence limits [-1.07,2.5]Gy Threatment time had no demonstrable influenc on TCP. Thus this tumor exhibits the fractionation sensitivity characteristic of a late-responding normal tissue, suggesting that an adequate fractionation schedule for malignant melanomas would be characterized by larger-than-conventional doses per fraction, possibly about 6 Gy per fraction. This is consistent with the conclusions of other authors. Tumor size, evaluated as mean tumor diameter, S, had a major impact on TCP: the number of target cells increased as a power function of S with exponent 0.72 (95% confidence limits) [1.49, 0.94]. In fact, a considerable amount of the heterogeneity in the dose-responce data could be removed by accounting for size. Thus, the weak, or absent dose response became highly significant. When a patient had multiple lesions, the responses of these to radiotherapy tended to be similar, thus implying that results were significantly influenced by a 'hidden parameter' (such as inherent radiosensitivity or immunological status). A test of the predictive value of the TCP-model was performed in a different series of 183 cutaneous and lymph node malignant melanomas. The observed dose-response relationship in this data set was in good agreement with the model prediction. A chi-square test for goodness-of-fit showed that the variation between predicted and observed results could be explained by the

    Surgery is performed more frequently now at days, due to the increasing incidence of melanoma and no-melanoma skin cancer. There are different opinions among dermatologic surgeons between to continue or discontinue antithrombotic therapy prior to the procedure, which increases the risk of thromboembolic events. Prophylaxis with oral antibiotics in the postsurgical period is controversial. To report the safety of surgery without suspending antithrombotic therapy and without oral antibiotic prophylaxis in dermatology surgery of patients with multiple comorbidities and polypharmacy. We designed a retrospective study. We included a total of 655 patients; 96.6% had at least one comorbidity; 27.7% used aspirin and 4.3% some type of antithrombotic therapy. The most common type of skin tumor was basal cell carcinoma with 69.8% . The complication rate was 4.2%; the most was wound dehiscence (1.1%), followed by partial necrosis (0.9%), infection (0.9%), reaction to foreign body (0.6%), complete necrosis (0.3%), bleeding (0.2%) and fistulae (0.2%). Based on the literature and our experience, dermatologic surgery is safe without suspending antithrombotic therapy or antibiotic prophylaxis in patients with multiple comorbidity.

    The purpose of these guidelines is to assist health care institutions establish protocols for the management of patients treated with iodine-131. These guidelines are written primarily for the use of Na 131 I in the treatment of benign and malignant thyroid disease. The principles have some application for the use of complex 131 I-labelled radiopharmaceuticals in that the treated patient will become a temporary radiation source and since contamination with body fluids of treated patients must be guarded against. The document outlines radiation protection and logistical concerns associated with the management of 131 I patients before, during and after therapy. These concerns include the safety of health care personnel, visitors, and any other persons who are at risk; and protection of the environment. (L.L.) 23 refs., 2 tabs

    1994-01-01

    When effectiveness is evaluated in brachytherapy with Ruthenium 106 special emphasis has to be put on tumor destruction and late side effects responsible for the definite functional results. We evaluated the late side effects of 22 uveal melanomas, which had been treated with 106 Ruthenium plaques. The tumor prominences ranged from 3 to 10 mm, the diameter from 4 to 9 disc diameters. In 4 patients the tumor involved the posterior pole, 14 melanomas were located in the midperiphery of the fundus, 4 tumors were ciliary body melanomas. The total radiation dose of the apex ranged from 100 to 240 Gy with a corresponding dose to the sclera between 540 to 1000 Gy. Because of the short half life of the plaque we have been using different dose rates (1.6-11 Gy/h). In 17/22 eyes adequate regression could be achieved by Ruthenium therapy alone. In one case additional laser treatment of the macular part of the melanoma had to be performed, Gamma Knife therapy was necessary in another melanoma with 10 mm tumor prominence. 3 recurrences led to enucleation. The mean follow up was 4.8 years ranging from 1 to 7 years. In 2/22 patients opticopathy caused severe visual impairment, in another 2 patients radiation maculopathy and opticopathy was observed. 7/22 developed vasculopathy with neovascularization treated by photocoagulation. In one case of focal radiation maculopathy laser treatment could prevent further visual impairment. The following factors are responsible for a higher incidence of late side effects: 1. High dose rate of the plaques in combination with a high radiation dose to the sclera 2. Location of the tumor within a minimum distance of 2 disc diameters to the optic nerve or macula 3. Tumor location at the ciliary body Laser treatment in case of neovascularization and focal radiation maculopathy is the only effective treatment with regard to late side effects. Ischemic maculopathy and radiation opticopathy are responsible for late visual impairment. (authors)

    A comparison of interview data on 595 patients with newly incident cutaneous melanoma, excluding lentigo maligna melanoma and acral lentiginous melanoma, with data from comparison subjects drawn from the general population, showed that melanoma risk increased in association with the frequency and severity of past episodes of sunburn, and also that melanoma risk was higher in subjects who usually had a relatively mild degree of suntan compared to those with moderate or deep suntan in both winter and summer. The associations with sunburn and with suntan were independent. Melanoma risk is also increased in association with a tendency to burn easily and tan poorly and with pigmentation characteristics of light hair and skin colour, and history freckles; the associations with sunburn and suntan are no longer significant when these other factors are taken into account. This shows that pigmentation characteristics, and the usual skin reaction to sun, are more closely associated with melanoma risk than are sunburn and suntan histories. PMID:3978032

    A series of boron neutron capture therapy (BNCT) studies has already germinated in 1972, with a view to establishing the BNCT particularly suited for the treatment of various types of malignant melanoma, and has been succeeded by research teams comprised of multi-disciplinary members. Twelve patients (7 men and 5 women, aged from 50 to 85 years) with malignant melanoma have been treated with BNCT; among them, six patients were completely cured, four had extremely reduced tumors, and two were still in the clinical process. The present Progress Report is a compilation of 39 research presentations for the recent two years. In this report, three patients are described. Of these, one patient had deep-seated lesions in right and left lymph nodes. These lesions were cured by the use of D 2 O that allowed neutron beams to reach them. Application of positron emission tomography to the diagnosis of melanoma is a highlight in this Report. (N.K.)

    Full Text Available ABSTRACT Introduction: In addition to well-established physical characteristics, Turner syndrome patients have distinct craniofacial morphology. Since short stature is the most typical characteristic, Turner syndrome patients are commonly treated with growth hormone in order to increase final height. At the same time, growth hormone treatment was found to influence craniofacial growth and morphology in various groups of treated patients. Whereas craniofacial characteristics of Turner syndrome patients are well documented, comparatively little is known of craniofacial morphology of those who are treated with growth hormone. Aim: The aim of this study was to investigate craniofacial morphology in Turner syndrome patients treated with growth hormone in comparison to healthy females. Materials and methods: The cephalometric evaluation was conducted on twenty lateral cephalograms of Turner syndrome patients (13.53 ± 4.04 years treated with growth hormone for at least one year (4.94 ± 1.92 years in average. As a control group, forty lateral cephalograms of healthy female controls, who matched Turner syndrome patients by chronological (11.80 ± 2.37 years and skeletal age, were used. Eleven angular, seven linear measurements and six dimensional ratios were measured to describe craniofacial morphology. Results: The results obtained for angular measurements, in cephalometric analyses for Turner syndrome patients treated with growth hormone, revealed bimaxillary retrognathism. The linear measurements indicated longer mandibular ramus, anterior cranial base and both anterior and posterior facial heights. However, posterior cranial base and maxilla were in proportion to the anterior cranial base, when comparing dimensional ratios. Anterior cranial base, maxilla and mandibular ramus were larger in proportion to mandibular body; as well as posterior facial height was when compared to anterior facial height.

    The type I interferons [both partially purified human leukocyte interferon (HuIFN-alpha) and recombinant alpha interferon] and the type II interferons have been shown to increase the expression of tumor-associated antigens in vitro. To determine whether HuIFN-alpha could increase tumor acquisition of the antimelanoma antibody 96.5 in vivo, five patients with metastatic malignant melanoma were treated with HuIFN-alpha at a dose of 3 X 10(6) units daily by im administration. Twenty-four hours after the first dose of HuIFN-alpha, 1 mg of antibody 96.5 labeled with 5 mCi of 111 In was coadministered with 19 mg of unlabeled 96.5. Five patients matched for metastatic site and lesion size who had not received HuIFN-alpha were also given a dose of 5 mCi of radiolabeled 96.5 at the same total antibody dose (20 mg). In patients treated with HuIFN-alpha, there was a statistically significant increase in the plasma half-life of the 111 In label (39.7 +/- 3.3 hr) compared to the untreated control group (29.8 +/- 3.2 hr). In addition, there was an increase in the apparent volume of distribution of the antibody in the HuIFN-alpha group (5.56 +/- 0.67 L) compared to controls (3.15 +/- 0.5 L) suggesting both an increased immediate extravascular distribution of radiolabeled antibody and a decrease in the subsequent rate of clearance of antibody from plasma. These two phenomena result in a 28% decrease in the area under the concentration curve in the HuIFN-alpha-treated group compared to controls. Computer analysis of whole-body scans from patients showed a threefold increase in radiolabeled antibody distributed to tumor relative to blood pool but no change in organ:blood ratios for liver, spleen, bone, or kidney compared to controls

    Radioactive iodine is the main radiopharmaceutical substance in the nuclear medicine field which used in diagnosis and treatment of patients suffering from thyroid cancer; thus it can be considered as the main source of the public and patient relative exposure. In this study, 192 patients were selected randomly and their radiation dose rate was measured at different levels of the patient's body (thyroid, knee, bladder) after one, twenty four and forty eight hours from availing the prescript quantity of the I-131. The collected data may serve in estimating the worker and public exposure related to the patient treated by I-131. (authors)

This presentation can be problematic for clinicians if they do not suspect melanoma and choose not to biopsy the lesion. We report a case of an elderly man with a history of invasive melanoma who presented with a furuncle-like lesion that was found to be in-transit metastatic melanoma.

    Full Text Available Abstract Background Increased level of serum S100B can serve as a marker of metastatic spread in patients with cutaneous melanoma (CM. In patients with elevated S100 B and/or clinical signs of disease progression PET-CT scan is a valuable tool for discovering metastases and planning treatment. The aims of this study were to determine whether regular measurements of serum S100B are a useful tool for discovering patients with CM metastases and to evaluate the diagnostic value of PET-CT during
