    The carcinogenic effect of plus ultraviolet A (PUVA)-therapy in psoriatic patients has been widely demonstrated, while data on the safety of narrow band (311 nm) ultraviolet B (nb-UVB) are scarce. We investigated the occurrence of melanoma and non-melanoma skin cancer (NMSC) in psoriatic patients treated with nb-UVB or PUVA-therapy. This retrospective study included patients affected by psoriasis, who had been treated with nb-UVB or PUVA-therapy. Clinical data and phenotypic risk factors were collected and a total body examination was performed at a routine appointment during the study period. We examined 92 patients (60 males and 32 females; mean age: 53.5 years, range: 20-83 years) treated with PUVA-therapy (42/92, 45%) or with nb-UVB (50/92, 55%) for 1-28 years (mean: 7.1 years). Among patients treated with PUVA, nine skin tumors (one melanoma, seven basal cell carcinoma (BCCs) and one squamous cell carcinoma (SCC)) were detected in 2/42 (4.7%) patients, while in the nb-UVB group, 14 skin tumors including two melanomas, four BCCs, and eight SCCs were diagnosed in 6/50 (12%) patients. A noteworthy number of NMSC were diagnosed in this Mediterranean population of patients exposed to high-dose UV treatment. A thorough risk-benefit evaluation should always be done before UV treatment and patients should be carefully monitored for skin cancer during and after treatment discontinuation.

    Recently, several new drugs have been licensed for advanced melanoma therapy, significantly changing the therapeutic landscape. Ipilimumab and vemurafenib were the first drugs that demonstrated a survival benefit over the long-standing standard therapy with dacarbazine. However, the comparative efficacy of these novel drugs has not been properly assessed yet. We conducted a retrospective analysis of all the Polish population treated between January 2012 and October 2016 with one of the following agents: ipilimumab (IPI), vemurafenib (VEM), dabrafenib (DAB), and classic chemotherapy (CTH). The main objective was to assess the overall survival of melanoma patients treated in real-world conditions, taking into account sequences of treatment. We identified 3397 patients with malignant melanoma treated for the first line and the second line. Patients receiving CTH were significantly older than those treated with the novel drugs. At the same time, the population treated with immunotherapy and targeted therapy was well balanced. Overall survival was significantly better for the novel drugs compared to classic chemotherapy in both lines (for the first line, VEM vs CTH HR = 0.72, 95% CI 0.65-0.81; p melanoma provide a significant advantage in survival over classic chemotherapy. Comparative assessment of IPI and VEM indicated no difference, but only immunotherapy-treated patients achieved long-lasting results. Our data on sequential treatment indicate that immunotherapy might be a better option for the first line rather than targeted therapy, but that conclusion requires further studies of the best way to manage the treatment of melanoma patients.

    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.

    There are limited data on the risk of non-melanoma skin cancer (NMSC) and melanoma skin cancer (MSC) among thiopurine-treated patients with ulcerative colitis (UC). Our aim was to investigate the risk while on, by cumulative years, and after stopping thiopurine therapy. Nationwide data were obtained from the Veterans Affairs (VA) health-care system during 2001-2011. We performed a retrospective cohort study evaluating patients with UC. Cox regression was used to investigate the association between thiopurines use and time to NMSC while adjusting for demographics, ultraviolet radiation exposure, and VA visiting frequency. A matched nested case-control study was conducted to investigate the association between thiopurine use and MSC. We included 14,527 patients with UC in the analysis, with a median follow-up of 8.1 years. A total of 3,346 (23%) patients used thiopurines for a median duration of 1.6 years. We identified 421 NMSC and 45 MSC cases. The adjusted hazard ratios of developing NMSC while on and after stopping thiopurines were 2.1 (P<0.0001) and 0.7 (P=0.07), respectively, as compared with unexposed patients. The incidence rate of NMSC among those who never used thiopurines was 3.7 compared with 5.8, 7.9, 8.3, 7.8, and 13.6 per 1,000 person-years for the 1st, 2nd, 3th, 4th, and 5th year of thiopurine use, respectively. No statistically significant association was observed between thiopurine use and MSC, odds ratio 0.8 (P=0.6). In this predominantly white male nationwide cohort, there was a twofold increase in the risk of NMSC while on thiopurines. The incidence rate of NMSC significantly increased with subsequent years of cumulative exposure to thiopurines. Stopping thiopurines reduced the risk of NMSC to pre-exposure levels irrespective of the prior exposure duration.

    BRAFV600E is a unique molecular marker for metastatic melanoma, being the most frequent somatic point mutation in this malignancy. Detection of BRAFV600E in blood could have prognostic and predictive value and could be useful for monitoring response to BRAF-targeted therapy. We developed a rapid, sensitive method for the detection and quantification of BRAFV600E in circulating free DNA (cfDNA) isolated from plasma and serum on the basis of a quantitative 5'-nuclease PCR (Taqman) in the presence of a peptide-nucleic acid. We validated the assay in 92 lung, colon, and melanoma archival serum and plasma samples with paired tumor tissue (40 wild-type and 52 BRAFV600E). The correlation of cfDNA BRAFV600E with clinical parameters was further explored in 22 metastatic melanoma patients treated with BRAF inhibitors. Our assay could detect and quantify BRAFV600E in mixed samples with as little as 0.005% mutant DNA (copy number ratio 1 : 20 000), with a specificity of 100% and a sensitivity of 57.7% in archival serum and plasma samples. In 22 melanoma patients treated with BRAF inhibitors, the median progression-free survival was 3.6 months for those showing BRAFV600E in pretreatment cfDNA compared with 13.4 months for those in whom the mutation was not detected (P=0.021). Moreover, the median overall survival for positive versus negative BRAFV600E tests in pretreatment cfDNA differed significantly (7 vs. 21.8 months, P=0.017). This finding indicates that the sensitive detection and accurate quantification of low-abundance BRAFV600E alleles in cfDNA using our assay can be useful for predicting treatment outcome.

    Pathologists sometimes disagree on the diagnosis of melanoma or its histopathologic staging, which may have implications for treatment and follow-up. For this reason, melanoma patients referred to Melanoma Institute Australia (MIA) for further treatment routinely have their pathology slides reviewed by MIA pathologists. This study sought to determine whether diagnosis, staging, and treatment of melanoma patients changed significantly after central pathology review. A total of 5,011 pairs of non-MIA and MIA pathology reports on the same primary melanoma specimen were reviewed. Differences in diagnosis, American Joint Committee on Cancer (AJCC) T classification, and treatment recommendations based on the non-MIA and MIA pathology reports were determined. A melanoma diagnosis changed in 5.1 % of cases after review. Where both pathologists agreed on a diagnosis of melanoma, AJCC T classification changed in 22.1 % after review. After MIA review, planned surgical excision margins changed in 11.2 % of cases, and a recommendation for sentinel lymph node biopsy (SLNB) changed in 8.6 %. Non-MIA reports less frequently contained criteria to define AJCC T classification (86.6 vs. 97.6 %), select appropriate surgical excision margins (95.2 vs. 99.6 %) and make a recommendation for SLNB (94.5 vs. 99.4 %), (each p treatment recommendations often change after pathology review by specialist melanoma pathologists. We recommend pathology review be considered for all patients attending specialist melanoma treatment centers.

    We recently initiated a program aimed to investigate the suitability of dynamic infrared imaging for following-up nodular melanoma patients treated with BNCT. The reason that makes infrared imaging attractive is the fact that it constitutes a functional and non-invasive imaging method, providing information on the normal and abnormal physiologic response of the nervous and vascular systems, as well as the local metabolic rate and inflammatory processes that ultimately appear as differences in the skin temperature. An infrared camera, with a focal plane array of 320x240 uncooled ferroelectric detectors is employed, which provides a video stream of the infrared emission in the 7-14 {mu}m wavelength band. A double blackbody is used as reference for absolute temperature calibration. After following a protocol for patient preparation and acclimatization, a basal study is performed. Subsequently, the anatomic region of interest is subjected to a provocation test (a cold stimulus), which induces an autonomic vasoconstriction reflex in normal structures, thus enhancing the thermal contrast due to the differences in the vasculature of the different skin regions. Radiation erythema reactions and melanoma nodules possess typically a faster temperature recovery than healthy, non-irradiated skin. However, some other non-pathological structures are also detectable by infrared imaging, (e.g. scars, vessels, arteriovenous anastomoses and injuries), thus requiring a multi-study comparison in order to discriminate the tumor signal. Besides the superficial nodules, which are readily noticeable by infrared imaging, we have detected thermal signals that are coincident with the location of non-palpable nodules, which are observable by CT and ultrasound. Diffuse regions of fast temperature recovery after a cold stimulus were observed between the third and sixth weeks post-BNCT, concurrent with the clinical manifestation of radiation erythema.

    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

    Ipilimumab, an immune checkpoint inhibitor targeting CTLA-4, prolongs survival in a subset of patients with metastatic melanoma (MM) but can induce immune-related adverse events, including enterocolitis. We hypothesized that baseline gut microbiota could predict ipilimumab anti-tumor response and/or intestinal toxicity. Twenty-six patients with MM treated with ipilimumab were prospectively enrolled. Fecal microbiota composition was assessed using 16S rRNA gene sequencing at baseline and before each ipilimumab infusion. Patients were further clustered based on microbiota patterns. Peripheral blood lymphocytes immunophenotypes were studied in parallel. A distinct baseline gut microbiota composition was associated with both clinical response and colitis. Compared with patients whose baseline microbiota was driven by Bacteroides (cluster B, n = 10), patients whose baseline microbiota was enriched with Faecalibacterium genus and other Firmicutes (cluster A, n = 12) had longer progression-free survival (P = 0.0039) and overall survival (P = 0.051). Most of the baseline colitis-associated phylotypes were related to Firmicutes (e.g. relatives of Faecalibacterium prausnitzii and Gemmiger formicilis), whereas no colitis-related phylotypes were assigned to Bacteroidetes. A low proportion of peripheral blood regulatory T cells was associated with cluster A, long-term clinical benefit and colitis. Ipilimumab led to a higher inducible T-cell COStimulator induction on CD4+ T cells and to a higher increase in serum CD25 in patients who belonged to Faecalibacterium-driven cluster A. Baseline gut microbiota enriched with Faecalibacterium and other Firmicutes is associated with beneficial clinical response to ipilimumab and more frequent occurrence of ipilimumab-induced colitis. © The Author 2017.

    To evaluate the incidence, risk factors, and dosages of proton beam therapy associated with cataract development, and long-term visual outcomes after treatment of uveal melanoma. All patients receiving primary proton beam therapy for uveal melanoma between 1998 and 2008 with no signs of cataract before irradiation were included. A minimum follow-up of 12 months was determined. Exclusion criteria included all applied adjuvant therapies such as intravitreal injections, laser photocoagulation, tumor resections, or re-irradiation. For subgroup analysis, we included all patients who underwent brachytherapy between 1998 and 2008 for uveal melanoma, considering the above mentioned inclusion and exclusion criteria. Two hundred and fifty-eight patients matched our inclusion criteria. Median follow-up was 72.6 months (12.0-167.4 months). Of these 258 patients, 71 patients (66.3 %) presented with cataract after 31.3 months (0.7-142.4 months), of whom 35 (20.4 %) required surgery after 24.2 (0.7-111.1 months) to ensure funduscopic tumor control. Kaplan-Meier estimates calculated a risk for cataract of 74.3 % after 5 years. There was no increase in metastasis or local recurrence in these patients. Patient's age was the sole independent statistically significant risk factor for cataract development. The probability of cataract occurrence significantly increased with doses to lens exceeding 15-20 CGE. Neither the appearance of cataract nor cataract surgery influenced long-term visual outcome. Cataract formation is the most frequent complication after irradiation. There is no benefit vis-a-vis brachytherapy with regard to cataract development. Data indicate a dose-effect threshold of 0.5 CGE for cataractogenesis, with significantly increasing risk above a dose of 15 CGE. Furthermore, cataract surgery can be performed without an increased risk for metastasis.

    Before licensing, ipilimumab was first made available to previously treated advanced melanoma patients through an expanded access programme (EAP) across Europe. We interrogated data from UK EAP patients to inform future clinical practice. Clinicians registered in the UK EAP provided anonymized patient data using a prespecified variable fields datasheet. Data collected were baseline patient characteristics, treatment delivered, toxicity, response, progression-free survival and overall survival (OS). Data were received for 193 previously treated metastatic melanoma patients, whose primary sites were cutaneous (82%), uveal (8%), mucosal (2%), acral (3%) or unknown (5%). At baseline, 88% of patients had a performance status (PS) of 0-1 and 20% had brain metastases. Of the patients, 53% received all four planned cycles of ipilimumab; the most common reason for stopping early was disease progression, including death from melanoma. Toxicity was recorded for 171 patients, 30% of whom experienced an adverse event of grade 3 or higher, the most common being diarrhoea (13%) and fatigue (9%). At a median follow-up of 23 months, the median progression-free survival and OS were 2.8 and 6.1 months, respectively; the 1-year and 2-year OS rates were 31 and 14.8%, respectively. The 2-year OS was significantly lower for patients with poorer PS (P<0.0001), low albumin concentrations (P<0.0001), the presence of brain metastases (P=0.007) and lactate dehydrogenase levels more than two times the upper limit of normal (P<0.0001) at baseline. These baseline characteristics are negative predictors of benefit from ipilimumab and should be taken into consideration before prescription.

    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. This information may be valuable in decisions about the dose and dose rates used to treat

    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.

    Ipilimumab (IPI) is a monoclonal antibody that targets the inhibitory CTLA4 receptor of T cells, enhancing T-cell-driven antitumor responses. IPI therapy in metastatic melanoma results in significant improvement in disease-free and overall survival, although after initial responses disease progression generally ensues. Identification of specific responses in tissue where melanoma tumor cells are subjected to IPI-driven immune attack may reveal mechanisms of treatment efficacy or resistance, permitting refinement of targeted therapeutic approaches. We used NanoString digital barcoding chemistry to identify changes in the transcriptome of metastatic melanoma cells before and after IPI treatment using two comprehensive panels containing a total of 1330 unique genes. Only patients who developed autoimmune disorders following treatment, signifying a robust immune response, were included. Despite evidence of an enhanced immune response, most patients eventually exhibited disease progression. Overall, data from five pre-IPI tumors and four post-IPI tumor samples (from three patients) permitted identification of several candidate genes that showed increased expression based on normalized counts after therapy. These included TTK (~3.1-fold, P=1.18e-4), which encodes a dual-specificity protein tyrosine kinase, a known cell cycle regulator, and BIRC5 (~3.0-fold, P=9.36e-4), which encodes the antiapoptotic protein survivin. Both TTK (MPS1) and survivin are targetable proteins against which a number of pharmacologic agents have been developed. CDK1, which encodes a protein tyrosine kinase known to phosphorylate survivin, was also upregulated (~3.2-fold, P=2.80-3). Tumor cell expression of TTK and survivin proteins was confirmed using immunohistochemistry in an expanded patient cohort. Differences in gene expression for several commonly encountered immune antigens, such as CD3, CD4, CD8, and CTLA4, were not statistically significant, likely reflecting the long length of time

    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.

    Full Text Available There is uncertainty about the risk of developing non-melanoma skin cancer (NMSC, including basal cell carcinoma and squamous cell carcinoma (SCC, in patients with atopic dermatitis (AD treated with oral immunosuppressive drugs. A total of 557 patients with AD treated with these drugs in the University Medical Center Utrecht and Groningen, the Netherlands, were analysed. NMSC after oral immunosuppressive treatment was reported in 18 patients (3.2%. The standardized incidence ratio for developing SCC was 13.1 (95% confidence interval (95% CI 6.5–19.7. Patients developing NMSC were older at the start of therapy (p<0.001 and data lock (p<0.001 compared with patients without NMSC. No significant differences were found in sex, cumulative days of oral immunosuppressive drugs and follow-up between these groups (p=0.42, p=0.88, and p=0.34, respectively. In interpreting these results it is important to include other factors, such as lack of association between treatment duration and tumour development and the long interval between treatment discontinuation and tumour development in some patients.

    Compare 5-year melanoma survival rates to rates in medical literature. Retrospective. Hospital in Tijuana, Mexico. White adult patients (N = 153) with superficial spreading and nodular melanoma, aged 25-72 years. Gerson's diet therapy: lactovegetarian; low sodium, fat and (temporarily) protein; high potassium, fluid, and nutrients (hourly raw vegetable/fruit juices). Metabolism increased by thyroid; calorie supply limited to 2600-3200 calories per day. Coffee enemas as needed for pain and appetite. 5-year survival rates by stage at admission. Of 14 patients with stages I and II (localized) melanoma, 100% survived for 5 years, compared with 79% of 15,798 reported by Balch. Of 17 with stage IIIA (regionally metastasized) melanoma, 82% were alive at 5 years, in contrast to 39% of 103 from Fachklinik Hornheide. Of 33 with combined stages IIIA + IIIB (regionally metastasized) melanoma, 70% lived 5 years, compared with 41% of 134 from Fachklinik Hornheide. We propose a new stage division: IVA (distant lymph, skin, and subcutaneous tissue metastases), and IVB (visceral metastases). Of 18 with stage IVA melanoma, 39% were alive at 5 years, compared with only 6% of 194 from the Eastern Cooperative Oncology Group. Survival impact was not assessed for stage IVB. Male and female survival rates were identical for stages I-IIIB, but stage IVA women had a strong survival advantage. The 5-year survival rates reported here are considerably higher than those reported elsewhere. Stage IIIA/B males had exceptionally high survival rates compared with those reported by other centers.

    To report a case of a choroidal melanoma and a discrete choroidal nevus that has transformed into a malignant melanoma 5 years after initial diagnosis. Retrospective case report. A diffuse macular choroidal melanoma and a discrete choroidal nevus located superonasal to the optic disk were diagnosed in the right eye of a 63-year-old woman in 2009. The patient was treated by ruthenium plaque radiotherapy for the choroidal melanoma, which consequently flattened and scarred. On a routine eye check in 2014, the nevus was found to have been transformed into a choroidal melanoma. It was treated with ruthenium plaque radiotherapy. Although extremely rare, patients with a uveal melanoma can develop an additional discrete uveal melanoma. This case highlights the importance of monitoring benign choroidal nevi in patients with a history of choroidal melanoma.

    Some studies have reported a possible association between exposure to tumour necrosis factor (TNF) inhibitors and an increased risk of melanoma. The aim of this study was to investigate the incidence of invasive cutaneous melanomas in patients with rheumatoid arthritis (RA) treated with TNF inhibitors (TNFi), other biologic disease modifying drugs and non-biologic therapy. Eleven biologic registers from nine European countries participated in this collaborative project. According to predefined exposure definitions, cohorts of patients with RA were selected. Using the country-specific general population of each register as reference, age, sex and calendar year standardised incidence ratios (SIRs) of invasive histology-confirmed cutaneous melanoma were calculated within each register. Pooled SIR and incidence rate ratios (IRRs) comparing biologic cohorts to biologic-naïve were calculated across countries by taking the size of the register into account. Overall 130 315 RA patients with a mean age of 58 years contributing 579 983 person-years were available for the analysis and 287 developed a first melanoma. Pooled SIRs for biologic-naïve, TNFi and rituximab-exposed patients were 1.1 (95% CI 0.9 to 1.4), 1.2 (0.99 to 1.6) and 1.3 (0.6 to 2.6), respectively. Incidence rates in tocilizumab and abatacept-exposed patients were also not significantly increased. IRR versus biologic-naïve patients were: TNFi 1.1 (95% CI 0.8 to 1.6); rituximab 1.2 (0.5 to 2.9). This large European collaborative project did not confirm an overall increased risk of melanoma following exposure to TNFi. Published by the BMJ Publishing Group Limited.

    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

    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 × 10 9 /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.

    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.

    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.

    Melanocortin-1 receptor (MC1R) plays a key role in skin pigmentation, and its variants are linked with a higher melanoma risk. The influence of MC1R variants on the outcomes of patients with metastatic melanoma (MM) treated with BRAF inhibitors (BRAFi) is unknown. We studied the MC1R status in a cohort of 53 consecutive BRAF-mutated patients with MM treated with BRAFi. We also evaluated the effect of vemurafenib in four V600 BRAF melanoma cell lines with/without MC1R variants. We found a significant correlation between the presence of MC1R variants and worse outcomes in terms of both overall response rate (ORR; 59% versus 95%, P = 0.011 univariate, P = 0.028 multivariate analysis) and progression-free survival (PFS) shorter than 6 months (72% versus 33%, P = 0.012 univariate, P = 0.027 multivariate analysis). No difference in overall survival (OS) was reported, probably due to subsequent treatments. Data in vitro showed a significant different phosphorylation of Erk1/2 and p38 MAPK during treatment, associated with a greater increase in vemurafenib IC50 in MC1R variant cell lines. © 2016 John Wiley & Sons A/S.

    Full Text Available Abstract 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 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.

    Ipilimumab, a monoclonal antibody against cytotoxic T lymphocyte antigen 4 (CTLA-4), has been shown to improve survival in patients with advanced metastatic melanoma. It also enhances immunity to NY-ESO-1, a cancer/testis antigen expressed in a subset of patients with melanoma. To characterize the association between immune response and clinical outcome, we first analyzed NY-ESO-1 serum antibody by ELISA in 144 ipilimumab-treated patients with melanoma and found 22 of 140 (16%) seropositive at baseline and 31 of 144 (22%) seropositive following treatment. These NY-ESO-1-seropositive patients had a greater likelihood of experiencing clinical benefit 24 wk after ipilimumab treatment than NY-ESO-1-seronegative patients (P = 0.02, relative risk = 1.8, two-tailed Fisher test). To understand why some patients with NY-ESO-1 antibody failed to experience clinical benefit, we analyzed NY-ESO-1-specific CD4(+) and CD8(+) T-cell responses by intracellular multicytokine staining in 20 NY-ESO-1-seropositive patients and found a surprising dissociation between NY-ESO-1 antibody and CD8 responses in some patients. NY-ESO-1-seropositive patients with associated CD8(+) T cells experienced more frequent clinical benefit (10 of 13; 77%) than those with undetectable CD8(+) T-cell response (one of seven; 14%; P = 0.02; relative risk = 5.4, two-tailed Fisher test), as well as a significant survival advantage (P = 0.01; hazard ratio = 0.2, time-dependent Cox model). Together, our data suggest that integrated NY-ESO-1 immune responses may have predictive value for ipilimumab treatment and argue for prospective studies in patients with established NY-ESO-1 immunity. The current findings provide a strong rationale for the clinical use of modulators of immunosuppression with concurrent approaches to favor tumor antigen-specific immune responses, such as vaccines or adoptive transfer, in patients with cancer.

    Investigate the impact of the reduction of the number of target lesions on immune-related response assessment in advanced melanoma patients treated with ipilimumab. Ninety patients (53 males, 37 females; age range: 25-87) with advanced melanoma treated with ipilimumab in two clinical trials were studied. Tumor measurements during trial allowing up to 5 lesions per organ and 10 lesions in total were retrospectively reviewed. A second set of tumor measurements allowing up to 2 lesions per organ and 5 lesions in total was generated. Immune-related response assessments by two measurements were compared. The number of target lesions was significantly reduced when up to 2 per organ and 5 in total lesions were allowed (Wilcoxon P immune-related response assessment using reduced number of lesions was highly concordant with assessment using the original number of lesions (Spearman r for the percent change on 1(st)-3(rd) follow-up: 0.860-0.970; κw for best immune-related response: 0.908). Median time-to-progression was 26.9 months (95%CI: 9.1-∞) by both assessments. Interobserver agreement of measurements was high for both assessments, with the concordance correlation coefficient above 0.98. Reduction of the number of target lesions did not significantly affect immune-related response assessment or the measurement variability in advanced melanoma patients treated with ipilimumab. Using up to 2 per organ and 5 in total target lesions is proposed to assess immune-related response, while it is important to keep other novel features of immune-related response criteria such as confirmation of progression and inclusion of new lesion measurements.

    Treatment with selective BRAF or MEK inhibitors is frequently associated with cutaneous toxicities, including squamous cell carcinoma (SCC), papillomas and rash. These cutaneous adverse effects are typically observed at a lower incidence during combined BRAF and MEK inhibitor therapy. Two male patients with stage IV metastatic BRAF-mutated melanoma were treated with a combination of a selective BRAF inhibitor and a selective MEK inhibitor (dabrafenib and trametinib, or encorafenib (LGX818) and binimetinib (MEK162)) within two different clinical trials. Ten and 150 days after treatment start respectively, the patients developed painful nodules on the legs. In addition, one patient developed symmetrical articulation pain and intermittent fever episodes. Based on the clinical and histological presentation, erythema nodosum-like panniculitis was diagnosed in both cases. No other aetiology could be found. After receiving topical or oral steroid treatment and anti-inflammatory analgesics, the painful nodular lesions disappeared several weeks later. In one case, a rebound of the painful nodules was observed when the combination treatment (dabrafenib and trametinib) was resumed after a 1-week unscheduled treatment interruption. Panniculitis has previously been described in association with BRAF inhibitor treatment, but not MEK inhibitor treatment. Combination treatment is usually associated with a lower incidence of cutaneous adverse events (AEs), as compared to monotherapy. Panniculitis was observed in two patients during combined BRAF and MEK inhibitor treatment. These cases illustrate the need for further research in a larger patient population to identify a possible link between combined BRAF and MEK inhibitor treatment and the incidence of panniculitis.

    An observational, questionnaire-based, cross-sectional study was performed to assess whether differences in coping behaviour (positive and negative strategies) between patients with either a recent diagnosis of malignant melanoma (MM) or with benign dermatological disease, were predictive of the diagnosis. Coping strategies were assessed with the German version of the stress-coping questionnaire (SVF 120) in 46 inpatients for whom surgery was planned at the Department of Dermatology, Medical University of Graz, Austria. Subjects were divided into two groups: patients with non-metastatic MM, and patients with benign dermatological diseases (controls). The risk for the diagnosis "melanoma" decreased with higher values of "situation control" (p = 0.007) and increased with higher values of resignation (p = 0.035) and trivialisation (p = 0.039). More-over, the risk for having a MM with thickness > 1 mm decreased in patients with higher values in positive coping strategies (p psychological interventions to improve coping in patients with MM, as differences in coping behaviour seem to appear even in the non-metastatic stage of the disease.

    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.

  10. 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.

    There is a growing body of evidence to support the efficacy of topical imiquimod in the treatment of primary skin carcinomas. Conflicting data exist concerning the use of imiquimod for the treatment of skin melanoma metastases. To date, only the impact of imiquimod on cytokines involved in immunological processes has been studied extensively. We report a woman successfully treated with imiquimod (once daily for 8 weeks) for skin melanoma metastases in whom we investigated the expression of molecules involved in metastasis and angiogenesis. Before and after treatment, a skin lesion was biopsied and the expression of the following molecules was investigated using real-time reverse transcription-polymerase chain reaction: matrix metalloproteinase (MMP)-1, 2 and 9 and their inhibitors KiSS-1 and tissue inhibitor of metalloproteinase (TIMP)-1, vascular endothelial growth factor (VEGF), fibroblast growth factor-2, and angiogenesis inhibitors (thrombospondin-1 and 2). Interferon (IFN)-alpha was also investigated as an in vivo marker of imiquimod activity. IFN-alpha was upregulated by the treatment. Under imiquimod, the following molecules were upregulated: TIMP-1, KiSS-1 and MMP-1. MMP-2 expression was not modified. MMP-9 expression was dramatically decreased. The expression of angiogenesis inhibitors was slightly increased but VEGF expression remained at a basal level. These results suggest that imiquimod could downregulate metastasis invasion and angiogenesis. However, these data were obtained at a transcriptional level and from a single case, and further investigations should include migration assays and additional cases in order to confirm that imiquimod may be safely used for treatment of melanoma metastases.

    We treated four cases of facial melanoma by BNCT with {sup 10}B-paraboronophenylalanine {center_dot} 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

  4. Circulating tumor cells in melanoma patients.

    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

    Data regarding the prognostic importance of BRAFV600 tumor mutations in high-risk, non-metastatic, stage 2 and 3 malignant melanoma (MM) patients are controversial. There is not sufficient information in the medical literature regarding the reliability of BRAF mutations as a predictive factor in prognosis and adjuvant treatment decision issues in this patient group. The data of 50 operated high-risk, non-metastatic, stage 2B/2C and 3 MM patients who received high-dose interferon alfa-2b therapy were evaluated retrospectively. BRAF mutations were analyzed by using microarray-based molecular methods. The associations between BRAF mutations and both clinicopathological characteristics and survival were assessed. Of the 50 patients, 52 % was female and 48 % was male, and the median age was 51.5 years. Twenty-three (46 %) and 27 (54 %) patients had stage 2B/2C and stage 3 disease, respectively. BRAF mutation was detected in 21 patients. The median overall survival (OS) was 58.1 months, whereas the median disease-free survival (DFS) was 22.7 months. When the OS and DFS were compared according to the BRAF mutation status, no difference was detected between the two groups. BRAF mutations were detected more frequently in tumors with mitosis and ulceration; however, no statistically significant difference was observed in other clinicopathological parameters. In conclusion, it is not appropriate to use BRAF mutations as a prognostic and predictive marker for selecting the treatment and assessing its outcomes in patients with early stage, high-risk MM.

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

    Retrospective evaluation of intraocular pressure, use of topical and systemic anti-glaucoma medication, secondary complications, local tumor control and survival in patients treated with trabeculectomy for the regulation of the intraocular pressure (IOP) after proton beam therapy for uveal melanoma. In this retrospective clinical case series we evaluated the follow-up of 15 patients receiving a trabeculectomy as surgical treatment if the IOP could not be lowered adequately by medications or laser surgery. All patients had received proton beam therapy for uveal melanoma at the Helmholtz-Zentrum Berlin between 1998 and 2010. The median IOP decreased significantly from 35 mmHg ± 8.8 before TE to 16 mmHg ± 8.2 (=52.3 %) six months after TE (Wilcoxon-Mann-Whitney-U Test, p<0.01). None of the patients needed any glaucoma medication six months after trabeculectomy. Two patients developed local recurrence during follow-up, which were independent of the trabeculectomy. One patient had to be enucleated due to intractable pain and suspected remaining tumor activity. One patient died due to metastasis. Trabeculectomy is an option in intractable glaucoma in patients with uveal melanoma after proton beam therapy in single cases. Secondary interventions are common. Inoculation metastases are possible. Secure local tumor control must be a prerequisite for filtrating operations.

    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.

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

    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.

    To report a case of unilateral multifocal melanoma in a patient with germ line BRCA-associated protein 1 mutation. Case report. A 67-year-old white woman with a family history of lung and liver cancers developed blurred visual acuity of 20/30 in the left eye. She was discovered to have two independent pigmented choroidal melanomas in the macula and superotemporally, both demonstrating overlying subretinal fluid and orange pigment. Both melanomas were treated with a single custom-designed Iodine 125 brachytherapy device. Upon systemic evaluation, asymptomatic renal cell carcinoma was found, and blood lymphocyte testing for germ line BRCA-associated protein 1 mutation was positive. Multifocal choroidal melanoma is exceedingly rare. Patients with uveal melanoma, especially if multifocal, and those with other systemic malignancy or family history of cancers should be tested for germ line BRCA-associated protein 1 mutation. Lifelong monitoring for other systemic malignancies is advised.

    Treatment of metastatic melanoma remains challenging, despite a variety of new and promising immunotherapeutic and targeted approaches to therapy. New treatment options are still needed to improve long-term tumour control. We present a case series of seven patients with metastatic melanoma who were treated individually with the anti-CD20 antibody rituximab between July 2014 and July 2015. Two of the patients were treated in an adjuvant setting. All patients had already received a variety of treatments. During an induction phase, the administration of four cycles of weekly rituximab 375 mg/m 2 body surface area was planned. After imaging, patients with stable disease continued therapy with rituximab 375 mg/m 2 body surface area every 4 weeks up to a maximum of 24 weeks. Two patients experienced grade 2 infusion reactions during the first infusion. Otherwise, treatment was well tolerated and there were no grade 3 or 4 side effects. Staging after the induction phase showed stable disease in five patients, and two patients had progressive disease. Median progression-free survival was 6.3 months (95% CI 4.97-7.53), median overall survival was 14.7 months (95% CI 4.52-24.94), and one patient was still alive in December 2016. In conclusion, rituximab might be a therapeutic option for metastatic melanoma. However, further studies on rituximab among larger patient cohorts are warranted. Evaluation of therapy in an adjuvant setting or in combination with other systemic treatment might, therefore, be of particular interest.

    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.)

    Malignant melanoma belongs to the most malignant and aggressive tumors due to its fast growing metastasis. Despite the fact that the incidence of melanoma has been on the increase for the past years and mortality to low and medium risk melanoma has decreased, the mortality of aggressive fast growing high risk melanomas has been stable. Diagnosis of “typical” melanomas, fulfilling ABCDEF criteria, usually does not cause any problems. Particular attention should be paid to the problems of fast growing melanomas, which are very similar to benign lesions at the beginning so they are often detected too late. Melanomas have two extreme properties: on one edge of the spectrum there are patients with small and thin skin lesions, who are usually completely cured by wide surgical excision. On the other edge of the spectrum there are patients with generalized metastatic disease. In these patients the treatment options are very limited and the probability to survive is about 6-9 months. The most significant factor for survival is the early melanoma detection. (author)

    Objectives To develop a digital intervention to prompt, support, and respond to the outcomes of total skin self-examinations (TSSEs) at home by people treated for cutaneous melanoma. Design A complex intervention development study. Setting Northeast Scotland. Participants Semistructured scoping interviews; people previously treated for cutaneous melanoma (n=21). Pilot testing: people treated for melanoma stages 0–2C (n=20); general practitioners (n=6); and a nurse specialist in dermatology (n=1). Intervention A tablet-based digital intervention designed to prompt and support TSSEs comprising instructional videos and electronic reporting (including photographs) to a clinical nurse specialist in dermatology, with subsequent clinical triage. Primary and secondary outcome measures Qualitative assessment of intervention feasibility and acceptability, and quantitative assessment of intentions and confidence to perform TSSEs in pilot participants. Results The majority of pilot participants were strongly positive and adhered well to the intervention (n=15), with 7 of these reporting symptoms of concern at some point during the 6-month pilot. 4 patients complied intermittently, 3 reporting skin problems at least once during the pilot, and 1 withdrew. 2 patients underwent skin surgery as a result of participating in the pilot, with 1 diagnosed as having a recurrent melanoma and the other, a benign lesion. A number of practical issues to improve the usability of the intervention were identified. The proportion of participants reporting intention to check their skin at least monthly increased during the intervention as did confidence to conduct a skin check. Conclusions People previously treated for cutaneous melanoma are prepared to use digital technology to support them in conducting TSSE. An intervention has been developed which is practical, effective and safe, and after addressing minor practical issues, could now be evaluated for clinical outcomes in a randomised

    A high number of nevi is the most significant phenotypic risk factor for melanoma and is in part genetically determined. The number of nevi decreases from middle age onward but this senescence can be delayed in patients with melanoma. We investigated the effects of nevus number count on sentinel node status and melanoma survival in a large cohort of melanoma cases. Out of 2,184 melanoma cases, 684 (31.3%) had a high nevus count (>50). High nevus counts were associated with favorable prognostic factors such as lower Breslow thickness, less ulceration and lower mitotic rate, despite adjustment for age. Nevus count was not predictive of sentinel node status. The crude 5- and 10-year melanoma-specific survival rate was higher in melanomas cases with a high nevus count compared to those with a low nevus count (91.2 vs. 86.4% and 87.2 vs. 79%, respectively). The difference in survival remained significant after adjusting for all known melanoma prognostic factors (hazard ratio [HR] = 0.43, confidence interval [CI] = 0.21-0.89). The favorable prognostic value of a high nevus count was also seen within the positive sentinel node subgroup of patients (HR = 0.22, CI = 0.08-0.60). High nevus count is associated with a better melanoma survival, even in the subgroup of patients with positive sentinel lymph node. This suggests a different biological behavior of melanoma tumors in patients with an excess of nevi. © 2015 The Authors. Published by Wiley Periodicals, Inc. on behalf of UICC.

    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.

    Full text of publication follows: Introduction: Malignant melanoma is a relatively uncommon cancer of increasing frequency. The aim of the present study was to evaluate prospectively the clinical value of SESTA-MIBI SPECT scintigraphy for diagnosis of subclinical metastases. Patients: We included 6 patients with advanced primary melanoma or suspicious metastatic disease. Results: The SESTA-MIBI SPECT scintigraphy revealed intense accumulation of radiotracer in primary skin lesions and was very important to detect occult metastases. Conclusion: Along the last year our group studied the usefulness of SESTA-MIBI SPECT scintigraphy for evaluation of advanced and recurrent melanoma lesions. TScintigraphy could be helpful for evaluation of patients with malignant melanoma in the investigation of lymph nodal invasion, local recurrence, and metastatic spread. (author)

    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.

    Vitiligo is a common skin disease characterized by autoimmune melanocyte destruction. Recent genetic studies suggest a lower susceptibility to melanoma in patients with vitiligo; however, lifetime melanoma prevalence in patients with vitiligo has not previously been studied. Nonmelanoma skin cancer (NMSC) prevalence has been studied, but only in small studies and with contradictory results. This retrospective, comparative cohort survey was designed to assess lifetime prevalences of melanoma and NMSC in patients with vitiligo compared with nonvitiligo controls. Patients with nonsegmental vitiligo, who visited our clinic between January 1995 and September 2010, and were aged 50 years or older at the time of the study, were invited to participate in a postal survey. The questions regarded demographics, vitiligo characteristics, phototherapy history, skin cancer risk factors and the number of skin cancers experienced during the patient's lifetime. Patients were asked to have their partner fill in a control questionnaire. All skin cancers were validated by a pathology report. In total 2635 invitations were sent and 1307 eligible questionnaires were returned (50%). Multivariate logistic regression models were used to quantify adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for associations between vitiligo and lifetime prevalences of melanoma and NMSC.  Adjusted for confounders, patients with vitiligo had a threefold lower probability of developing melanoma (adjusted OR 0·32; 95% CI 0·12-0·88) and NMSC (adjusted OR 0·28; 95% CI 0·16-0·50). Subgroup analyses of patients treated with narrowband ultraviolet (UV) B, and psoralen and UVA did not show dose-related trends of increased age-adjusted lifetime prevalence of melanoma or NMSC. Our findings suggest that patients with vitiligo have a decreased risk of both melanoma and NMSC. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

    Full Text Available Purpose: The incidence of non-melanoma skin cancer (NMSC has been increasing over the past 30 years. There are different treatment options and surgical excision is the most frequent treatment due to its low rates of recurrence. Radiotherapy is an effective alternative of surgery, and brachytherapy (BT might be a better therapeutic option due to high radiation dose concentration to the tumor with rapid dose fall-off resulting in normal tissues sparing. The aim of this review was to evaluate the local control, toxicity, and cosmetic outcomes in NMSC treated with high-dose-rate BT (HDR-BT. Material and methods: In May 2016, a systematic search of bibliographic database of PubMed, Web of Science, Scopus, and Cochrane Library with a combination of key words of “skin cancer”, “high dose rate brachytherapy”, “squamous cell carcinoma”, “basal cell carcinoma”, and “non melanoma skin cancer“ was performed. In this systematic review, we included randomized trials, non-randomized trials, prospective and retrospective studies in patients affected by NMSC treated with HDR-BT. Results: Our searches generated a total of 85 results, and through a process of screening, 10 publications were selected for the review. Brachytherapy was well tolerated with acceptable toxicity and high local control rates (median: 97%. Cosmetic outcome was reported in seven study and consisted in an excellent and good cosmetic results in 94.8% of cases. Conclusions : Based on the review data, we can conclude that the treatment of NMSC with HDR-BT is effective with excellent and good cosmetics results, even in elderly patients. The hypofractionated course appears effective with very good local disease control. More data with large-scale randomized controlled trials are needed to assess the efficacy and safety of brachytherapy.

  12. Primary localization and tumor thickness as prognostic factors of survival in patients with mucosal melanoma.

    Tarun Mehra

    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.

  13. Activation of Wnt/β-catenin signaling increases apoptosis in melanoma cells treated with trail.

    Directory of Open Access Journals (Sweden)

    Zachary F Zimmerman

    Full Text Available While the TRAIL pathway represents a promising therapeutic target in melanoma, resistance to TRAIL-mediated apoptosis remains a barrier to its successful adoption. Since the Wnt/β-catenin pathway has been implicated in facilitating melanoma cell apoptosis, we investigated the effect of Wnt/β-catenin signaling on regulating the responses of melanoma cells to TRAIL. Co-treatment of melanoma cell lines with WNT3A-conditioned media and recombinant TRAIL significantly enhanced apoptosis compared to treatment with TRAIL alone. This apoptosis correlates with increased abundance of the pro-apoptotic proteins BCL2L11 and BBC3, and with decreased abundance of the anti-apoptotic regulator Mcl1. We then confirmed the involvement of the Wnt/β-catenin signaling pathway by demonstrating that siRNA-mediated knockdown of an intracellular β-catenin antagonist, AXIN1, or treating cells with an inhibitor of GSK-3 also enhanced melanoma cell sensitivity to TRAIL. These studies describe a novel regulation of TRAIL sensitivity in melanoma by Wnt/β-catenin signaling, and suggest that strategies to enhance Wnt/β-catenin signaling in combination with TRAIL agonists warrant further investigation.

    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.

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

    Anna M. Leung

    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.

    For more than 20 years interleukin-2 (IL2) was the preferred treatment for medically fit metastatic melanoma patients, but recently two new agents, ipilimumab and vemurafenib, were approved for stage IV disease. Single-institution data were used to determine the long-term survival rate for IL2-treated melanoma patients, and whether use of inpatient IL2 had declined recently. Between May 1987 and April 2010, 150 patients were hospitalized for high-dose, intravenous (i.v.) IL2. The average number of IL2 patients increased from 5.4 per year during 1987-1991 to 5.8 during 1992-1997 after regulatory approval of IL2, to 8.3 during 1998-2006 after a marketing indication in metastatic melanoma was granted, but dropped to 3.0 during 2007-2010. At the time of treatment, median age was 52 years; 27% were 60 years of age or older. At the time of analysis 122 patients were deceased. Median survival from the start date of IL2 treatment was 15.6 months, with a 20% 5-year survival. Among patients enrolled in clinical trials, there were as many nonresponders who survived 5 years as responders, which is consistent with a delayed immunotherapy benefit. In the absence of long-term survival data for these newer agents, IL2 probably should still be the preferred initial treatment for most patients with metastatic melanoma who are medically fit.

    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.

    Approximately 25% of melanoma patients with locoregional metastases are nonresponsive to new molecular target therapy and immunotherapy. When metastases are located in the pelvis, melphalan hypoxic perfusion can be an optional treatment. Because methylation of MGMT promoter increases the efficacy of alkylating agents, studies on melanoma outcome of patients treated with melphalan regional chemotherapy should consider this epigenetic change. This study aims to evaluate whether the survival of stage III melanoma patients treated with melphalan regional chemotherapy may be correlated with MGMT methylation status. The metastatic tissues of 27 stage III melanoma patients with locoregional metastases located in the pelvis subjected to melphalan hypoxic pelvic perfusion were examined. The methylation status of the MGMT promoter was investigated by MS-MLPA probes analysis and the presence of the BRAF V600E mutation was analyzed by CAST-PCR. The median survival times were estimated using the Kaplan-Meier curves and were stratified according to the clinicopathological characteristics of patients and lesions. The overall median survival time was 17 months. The 1-year, 3-year, and 5-year survival rates were 66.7, 18.5, and 7.4%, respectively. Disease stage, burden, and percentage of MGMT methylation significantly affected survival. We estimated an MGMT promoter methylation cut-off of at least 14%, which was significantly associated with a longer survival after melphalan regional chemotherapy. Our data suggest that MGMT promoter methylation could be an important factor in determining which melanoma patients should receive melphalan regional chemotherapy, but its prognostic significance in the routine clinical setting needs to be clarified in a larger study.

    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.

    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.

    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

    Full Text Available Cullen’s sign, ecchymosis of the subcutaneous periumbilical tissue often described in association with non-malignant conditions such as ruptured ectopic pregnancy or acute pancreatitis, has been reported in malignancies involving the abdomen. In melanoma, hematoma-like metastasis has been observed and can resolve with an effective therapy. We observed resolution of Cullen’s sign (probably hematoma-like metastasis in a patient with metastatic melanoma. The patient was participating in a phase I clinical trial and treated with TH-302, a hypoxia-activated prodrug. After 2 months on study, complete resolution of Cullen’s sign resolved in concert with extracranial response in lung, liver, and lymph node metastases. Based on the dramatic extracranial response to this investigational agent, additional patients with metastatic melanoma without evidence of brain metastasis were treated on study with TH-302.

    Full Text Available In melanoma development, oncogenic process is mediated by genetic and epigenetic mutations, and few studies have so far explored the role of DNA methylation either as predisposition factor or biomarker. We tested patient samples for germline CDKN2A methylation status and found no evidence of inactivation by promoter hypermethylation. We have also investigated the association of clinical characteristics of samples with the DNA methylation pattern of twelve genes relevant for melanomagenesis. Five genes (BAP1, MGMT, MITF, PALB2, and POT1 presented statistical association between blood DNA methylation levels and either CDKN2A-mutation status, number of lesions, or Breslow thickness. In tumors, five genes (KIT, MGMT, MITF, TERT, and TNF exhibited methylation levels significantly different between tumor groups including acral compared to nonacral melanomas and matched primary lesions and metastases. Our data pinpoint that the methylation level of eight melanoma-associated genes could potentially represent markers for this disease both in peripheral blood and in tumor samples.

    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)

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

    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

    Primary uveal malignant melanoma of the ciliary body associated with nodular extrascleral extension, diffuse iris-angle infiltration, and secondary glaucoma is usually treated by prompt enucleation. We report a patient with ciliary body melanoma associated with nodular extrascleral extension and diffuse infiltration of the iris and angle treated conservatively because the fellow eye was blind. The clinical features and surgical management of a melanoma of the ciliary body with extrascleral extension and diffuse infiltration of the iris and angle are presented. The tumor was treated with focal I-125 plaque radiotherapy followed by supplemental whole anterior segment I-125 plaque radiotherapy. The patient has been followed for over 2.5 years since the initial plaque radiotherapy and over 1.5 years since the supplemental whole anterior segment radiotherapy. His visual acuity is correctable to 20/40 OD and there is no evidence of metastatic disease. His glaucoma is well controlled following trabeculectomy and tube shunt procedure. Whole anterior segment plaque radiotherapy for ciliary body melanoma with diffuse iris-angle infiltration provided palliative local tumor control without significant local complications through available follow-up.

    Conjunctival malignant melanoma (CMM) is a rare malignancy and in the advanced setting there is no effective treatment. In contrast, half of cutaneous melanomas have BRAF mutations and treatment with BRAF inhibitors is established for patients with disseminated disease. The most common form of ocular melanoma, uveal melanoma, lacks these mutations, however, their presence has been reported for CMM. We used the BRAF inhibitor vemurafenib to treat a 53 year-old female suffering from a BRAF(V600E) mutated metastatic CMM. The patient benefited from the treatment, a response was evident within a week and she experienced a progression free survival of four months. To our knowledge, this is the first described case of response to vemurafenib treatment in a patient with ocular melanoma.

    To describe the method of diagnosis, clinical management and adherence to clinical practice guidelines for melanoma patients at high risk of a subsequent primary melanoma, and compare this with melanoma patients at lower risk. The Melanoma Patterns of Care study was a population-based, observational study based on doctors' reported clinical management of melanoma patients in New South Wales, Australia, diagnosed with in situ or invasive melanoma over a 12-month period from October 2006. Of 2605 patients with localised melanoma, 1019 (39%) were defined as at higher risk due to the presence of one or more of the following factors: a family history of melanoma (11%), multiple primary melanomas (17%), or many naevi (24%). Compared to patients at lower risk, high risk patients were more likely to receive their initial care from a primary care physician (56% vs 50%, P = 0.002), have their melanoma detected during a routine skin check (40% vs 33%, P < 0.001), have their lesion assessed with dermoscopy (63% vs 56%, P = 0.002), and be encouraged to have skin surveillance (84% vs 77%, P < 0.001) and skin self-examination (87% vs 83%, P = 0.03). Higher socioeconomic status and urban residence were associated with patients at higher risk receiving initial treatment from a specialist doctor. Clinical management of higher risk patients was more likely to conform to clinical practice guidelines for diagnosis and skin surveillance than to melanoma patients at lower risk. © 2016 The Australasian College of Dermatologists.

    To evaluate the outcomes of iris melanoma managed with plaque radiotherapy on the basis of the initial presence or absence of glaucoma. Retrospective, comparative case series. A total of 144 patients. Custom-designed iodine-125 plaque radiotherapy delivering planned 8000 cGy to melanoma apex using transcorneal application. Tumor control and treatment-related complications. Of 144 patients with iris melanoma, glaucoma was present at the initial visit in 58 (40%). Causes of elevated intraocular pressure included angle infiltration by melanoma in 50 patients (86%), angle neovascularization in 4 patients (7%), and hyphema in 4 patients (7%). At presentation, the eyes displaying iris melanoma with glaucoma (vs. without glaucoma) were statistically more likely to display angle tumor (66% vs. 43%), with minimal thickness (1.9 vs. 2.9 mm), and melanoma seeding in iris stroma (7 vs. 3 clock hours) and angle (5 vs. 2 clock hours). Plaque radiotherapy was performed in all cases. Kaplan-Meier estimates at 7 years post-treatment revealed no statistical differences in outcomes of local recurrence (14% vs. 15%), enucleation (14% vs. 11%), or metastasis (2% vs. 0%) comparing eyes with and without glaucoma. Of the entire group, multivariate analysis for factors predictive of recurrence included partial (vs. complete) anterior segment irradiation and postradiotherapy glaucoma. Factors related to enucleation included diabetes mellitus, poor initial visual acuity, higher radiation dose to tumor apex, and tumor recurrence. There were no factors predictive of metastasis. Iodine-125 plaque radiotherapy provides adequate tumor control for iris melanoma with a low metastatic potential of 1% at 7 years. Iris melanoma with secondary glaucoma showed a statistically significant greater likelihood of flat tumor with iris and angle seeding and no difference in outcomes compared with eyes without glaucoma.

    To explore the knowledge, attitudes, and practices associated with meditation among people with melanoma and investigate the relationship between perceived stress, trait mindfulness, and meditation. Factors associated with interest to participate in an online meditation program were also explored. A survey-based cross-sectional study of 291 patients attending a melanoma outpatient clinic assessed knowledge of meditation, attitudes toward meditation using Determinants of Meditation Practice Inventory (DMPI), and meditation experience. Perceived stress and trait mindfulness were measured using the Perceived Stressed Scale and Cognitive and Affective Mindfulness Scale, respectively. Participants who had tried meditation (43%) were likely to be younger, female, and have completed higher education or be employed. Perceived stress score was higher among women, younger participants, and those treated in the past year but did not differ by melanoma stage. Participants reported a good understanding of the potential benefits of meditation, but even among people with meditation experience, common misconceptions prevailed. The main barrier to meditation was a perceived lack of knowledge about meditation . Higher DMPI scores were associated with lower education, moderate to low access to service centers, or living in disadvantaged neighborhoods . Participants practicing meditation that involved self-reflection reported less stress and higher trait mindfulness compared with participants practicing another type of meditation. People interested in participating in an online meditation-based program reported higher perceived stress than those not interested. A meditation-based intervention teaching self-reflective practices, targeted at people with melanoma, may have the potential to assist them with managing their stress.

    Serum copper levels (SCL) and serum zinc levels (SZL) were evaluated in malignant melanoma patients at various clinical stages. Copper levels were generally found to be elevated, reflecting the degree and extent of tumor activity. Zinc levels and, hence, SCL:SZL ratios did not reflect tumor activity. SCL appeared to prognosticate disease progression in that all patients whose values never declined below 150 ..mu..g/100 ml died during the course of the study. However, not all patients who died from tumor metastases displayed persistent elevations of SCL. Patients receiving BCG immunotherapy appeared to have higher SCL than untreated patients.

    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.

    Tuberculosis (TB) is considered a pulmonary disease that can however disseminate to other organs through hematogenous dissemination following primary TB infection. Evolution of the disease can either be precocious, before healing of the primary infection, or late after primary infection, due to reactivation of initial lesions usually because of simultaneous immunosuppressive factors such as diabetes, renal disease, hepatic disease or different type of immunosuppressing treatments. Rare cases when tuberculosis and cancer are diagnosed at the same time create diagnostic difficulties and therapeutic challenges. We present the case of an asymptomatic 52-year-old female that was diagnosed "by chance, at the right moment" with a form of skin melanoma on the right forearm, for which she received a rather well tolerated cytostatic treatment. At the end of this treatment, she was also investigated for a breast mass that proved to be benign; however, enlarged lymph nodes were discovered in the right armpit were discovered upon further investigation. One of the lymph nodes was surgically removed, as first suspicion was of a metastasis from the skin melanoma. However, it was lymph node tuberculosis therefore anti-tuberculosis treatment was initiated. The patient tolerated the treatment with minor side effects. On few occasions, a patient can be diagnosed with incipient stages of skin melanoma and even more rarely the same patient is diagnosed and treated prematurely for lymph node tuberculosis. Sometimes, a successful outcome needs an organized and well-educated patient and a little luck.

    Ipilimumab was the first FDA-approved agent for advanced melanoma to improve survival and represents a paradigm shift in melanoma and cancer treatment. Its unique toxicity profile and kinetics of treatment response raise novel patient education challenges. We assessed patient perceptions of ipilimumab therapy across the treatment trajectory. Four patient cohorts were assessed at different time points relative to treatment initiation: (1) prior to initiation of ipilimumab (n = 10), (2) at weeks 10-12 before restaging studies (n = 11), (3) at week 12 following restaging studies indicating progression of disease (n = 10), and (4) at week 12 following restaging studies indicating either a radiographic response or disease stability (n = 10). Patients participated in a semistructured qualitative interview to assess their experiences with ipilimumab. Quality of life was assessed via the Functional Assessment of Cancer Therapy-General and its Melanoma-specific module. Perceived quality of life was comparable across cohorts, and a majority of the sample understood side effects from ipilimumab and the potential for a delayed treatment response. Patients without progression of disease following restaging studies at week 12 held more positive views regarding ipilimumab compared to patients who had progressed. Patients generally regarded ipilimumab positively despite the risk of unique toxicities and potential for delayed therapeutic responses; however, those with progression expressed uncertainty regarding whether taking ipilimumab was worthwhile. Physician communication practices and patient education regarding realistic expectations for therapeutic benefit as well as unique toxicities associated with ipilimumab should be developed so that patients can better understand the possible outcomes from treatment.

    To critically assess the status of molecular prognostic testing and its use for individualized patient care in uveal melanoma. Perspective, literature review, evidence assessment, and commentary. Evaluation of selected articles from the literature and the authors' clinical and laboratory studies. The most accurate molecular tests for predicting metastatic death in patients with uveal melanoma currently involve automated techniques for assessing deoxyribonucleic acid (DNA) copy number alterations and gene expression profiling. Most tests reported in the literature to date do not provide adequate scientific and statistical validation to be used outside of an ethically supervised investigational environment. Many cytogenetic and molecular prognostic tests for uveal melanoma have been reported, yet few have reached the standards required for routine clinical testing. Clinicians must understand the statistical and scientific limitations of the tests they are using, and appropriate ethical oversight is essential until such time that validated testing instruments are available that are performed in a standardized clinical testing environment. Well-controlled prospective studies are necessary to identify the most accurate, widely accessible, and affordable tests for routine clinical use.

  10. Circulating Tumour DNA for Monitoring Treatment Response to Anti-PD-1 Immunotherapy in Melanoma Patients

    2017-08-01

    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.

    Survival data are mixed comparing patients with multiple primary melanomas (MPM) to those with single primary melanomas (SPM). To compare MPM vs. 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 from 1973-2011 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 MPM, 887 SPM) without covariates showed a significant survival disadvantage for MPM patients (chi-squared = 39.29, p < 0.001). However, a multivariate Cox proportional hazards model showed no significant survival difference (hazard ratio = 1.07, p = 0.55). Restricting the multivariate analysis to invasive melanomas also showed no significant survival difference (hazard ratio = 0.99, p = 0.96). Breslow depth, ulceration status, and specific cause of death was not available for all patients. Patients with MPM had similar survival time as patients with SPM. Copyright © 2018.

    Xeroderma pigmentosum (XP) is an autosomal recessive disorder characterized by a defect in DNA repair and subsequent increased frequency of cutaneous malignant neoplasms, including melanoma. In patients with XP, patient and family education and aggressive UV radiation protection are the primary means of skin cancer prevention. An important secondary measure in decreasing morbidity and mortality in these patients involves early detection of skin cancers, particularly melanomas. We describe a 39-year-old woman with XP who developed 38 primary melanomas along with 6 squamous cell carcinomas and 70 basal cell carcinomas over a 23-year period. During this time, a 3-fold management approach of total-body cutaneous examination, total-body photography, and dermoscopy was used in the care of the patient. The thickest melanoma had a Breslow thickness of 1.07 mm, and the mean Breslow thickness of her detected melanomas was 0.18 mm. The ratio of benign to malignant biopsied suspicious melanocytic lesions during 23 years of follow-up was 0.9:1. All melanomas were treated using wide local excision, and she had no evidence of local or in-transit metastases of any of her malignant neoplasms at the most recent follow-up examination. Conclusion Monthly follow-up using total-body cutaneous examinations, total-body photography, and dermoscopy is an important 3-fold secondary management technique for this unique patient, allowing early detection of her melanomas.

    Melanomas are initially excised in primary care, and rates vary internationally. Until now, there has been no strong evidence one way or the other that excising melanomas in primary care is safe or unsafe. European guidelines make no recommendations, and the United Kingdom (UK) melanoma guidelines require all suspicious skin lesions to be initially treated in secondary care based on an expert consensus, which lacks supporting evidence, that primary care excision represents substandard care. Despite this, studies have found that up to 20% of melanomas in the UK are excised by general practitioners (GPs). Patients receiving primary care melanoma excision may fear that their care is substandard and their long-term survival threatened, neither of which may be justified. Scottish cancer registry data from 9367 people diagnosed with melanoma in Scotland between 2005 and 2013 were linked to pathology records, hospital data and death records. A Cox proportional hazards regression analysis, adjusting for key confounders, explored the association between morbidity and mortality and setting of primary melanoma excision (primary versus secondary care). A pooled estimate of the relative hazard of death of having a melanoma excised in primary versus secondary care including 7116 patients from a similar Irish study was also performed. The adjusted hazard ratio (95% CI) of death from melanoma for those having primary care excision was 0.82 (0.61-1.10). Those receiving primary care excision had a median (IQR) of 8 (3-14) out-patient attendances compared to 10 (4-17) for the secondary care group with an adjusted relative risk (RR) (95% CI) of 0.98 (0.96-1.01). Both groups had a median of 1 (0-2) hospital admissions with an adjusted rate ratio of 1.05 (0.98-1.13). In the meta-analysis, with primary care as the reference, the pooled adjusted hazard ratio (HR, 95% CI) was 1.26 (1.07-1.50) indicating a significantly higher all-cause mortality among those with excision in secondary care

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

    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.

  17. STAT3 single nucleotide polymorphism rs4796793 SNP does not correlate with response to adjuvant IFNα therapy in stage III melanoma patients

    Full Text Available Interferon alpha (IFNα is approved for adjuvant treatment of stage III melanoma in Europe and the US. Its clinical efficacy, however, is restricted to a subpopulation of patients while side effects occur in most of treated patients. Thus, the identification of predictive biomarkers would be highly beneficial to improve the benefit to risk ratio. In this regard, STAT3 is important for signaling of the IFNα receptor. Moreover, the STAT3 single nucleotide polymorphism (SNP rs4796793 has recently been reported to be associated with IFNα sensitivity in metastatic renal cell carcinoma. To translate this notion to melanoma, we scrutinized the impact of rs4796793 functionally and clinically in this cancer. Interestingly, melanoma cells carrying the minor allele of rs4796793 were the most sensitive to IFNα in vitro. However, we did not detect a correlation between SNP genotype and STAT3 mRNA expression for either melanoma cells or for peripheral blood lymphocytes. Next, we analyzed the impact of rs4796793 on the clinical outcome of 259 stage III melanoma patients of which one third had received adjuvant IFNα treatment. These analyses did not reveal a significant association between the STAT3 rs4796793 SNP and patients’ progression free or overall survival when IFN treated and untreated patients were compared. In conclusion, STAT3 rs4796793 SNP is no predictive marker for the efficacy of adjuvant IFNα treatment in melanoma patients.

    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.

  1. Pentoxifylline Inhibits WNT Signalling in β-Cateninhigh Patient-Derived Melanoma Cell Populations.

    Directory of Open Access Journals (Sweden)

    Beata Talar

    Full Text Available The heterogeneity of melanoma needs to be addressed and combination therapies seem to be necessary to overcome intrinsic and acquired resistance to newly developed immunotherapies and targeted therapies. Although the role of WNT/β-catenin pathway in melanoma was early demonstrated, its contribution to the lack of the melanoma patient response to treatment was only recently recognized. Using patient-derived melanoma cell populations, we investigated the influence of pentoxifylline on melanoma cells with either high or low expression of β-catenin.Our results indicate that pentoxifylline inhibits the activity of the canonical WNT pathway in melanoma cell populations with high basal activity of this signalling. This is supported by lowered overall activity of transcription factors TCF/LEF and reduced nuclear localisation of active β-catenin. Moreover, treatment of β-cateninhigh melanoma cell populations with pentoxifylline induces downregulation of genes that are targets of the WNT/β-catenin pathway including connective tissue growth factor (CTGF and microphthalmia-associated transcription factor (MITF-M, a melanocyte- and melanoma cell-specific regulator.These results suggest that pentoxifylline, a drug approved by the FDA in the treatment of peripheral arterial disease, might be tested in a subset of melanoma patients with elevated activity of β-catenin. This pharmaceutical might be tested as an adjuvant drug in combination therapies when the response to immunotherapy is prevented by high activity of the WNT/β-catenin pathway.

    Guidelines recommend that health professionals identify and manage individuals at high risk of developing melanoma, but there is limited population-based evidence demonstrating real-world practices. A population-based, observational study was conducted in the state of New South Wales, Australia to determine doctors' knowledge of melanoma patients' risk and to identify factors associated with better identification and clinical management. Data were analysed for 1889 patients with invasive, localised melanoma in the Melanoma Patterns of Care study. This study collected data on all melanoma diagnoses notified to the state's cancer registry during a 12-month period from 2006 to 2007, as well as questionnaire data from the doctors involved in their care. Three-quarters (74%) of patients had doctors who were aware of their risk factor status with respect to personal and family history of melanoma and the presence of many moles. Doctors working in general practice, skin cancer clinics and dermatology settings had better knowledge of patients' risk factors than plastic surgeons. Doctors were 15% more likely to know the family history of younger melanoma patients (risk status, by doctors practising in plastic surgery, dermatology and skin cancer clinic settings, and by female doctors. Both patient-related and doctor-related factors were associated with doctors' recognition and management of melanoma patients' risk and could be the focus of strategies for improving care.

    To evaluate the immunomodulatory effect on lymphocyte subsets, dendritic cells (DC), Th1 / Th2 / Th17 and inflammatory cytokines on systemic level and/or in the tumor microenvironment of mice with or without melanoma. Peripheral blood and/or primary tumors samples were obtained of mice with B16 melanoma treated or not with a hydroalcoholic extract of Uncaria tomentosa (UT) with 5.03% of pentacyclic oxindole alkaloids (UT-POA) obtained from the bark of the plant. All cell assays and cytokine measurements were performed by flow cytometry. UT-POA systemically increased CD4/CD8a relation while cell activation was inversely proportional; increased the proportion of DCm; induced a pro-inflammatory Th1 profile and reduced Th17 response. TNF-α and IL-17A positively and negatively correlated with CD4/CD8a relation. The increase of Th1 (TNF-α) may result in the increase of CD4 or M1 macrophage activation. Although UT-POA shows increased DCm, is not dose-dependent. Th17(IL-17A) decreased can support the function of CD8a lymphocytes. UT-POA shows better systemic immunomodulatory effects than intratumoral.

    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 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 purpose of this study was to report, we believe for the first time, a histological study of choroidal malignant melanoma treated by carbon ion beam radiotherapy. A 75-year-old Japanese man was diagnosed as having a choroidal melanoma after undergoing magnetic resonance imaging (MRI). Positron emission tomography (PET) revealed a hot spot in the same location as the intraocular mass seen in MRI. Carbon ion radiotherapy was performed with a total dose of 77 Gy, and the hot spot seen by PET disappeared completely. At 15 months after carbon ion therapy, the eye had to be enucleated because of uncontrollable ocular hypertension. It was examined histologically in serial sections. A large tumor mass (15 x 12 mm) with high pigmentation was found in the vitreous space. Almost all tumor cells showed necrosis in every section. A small number of intact tumor cells were present at the periphery. The overlying retina did not show any necrosis, but showed mild to moderate gliosis. No intraretinal hemorrhage, lipid deposit, or protein exudate was apparent. Almost all tumor cells showed necrosis after radiotherapy with a carbon ion beam. However, the effect on the adjacent tissues was determined as minimal in histological analysis. (author)

    Full Text Available Ixabepilone (BMS-247550, an epothilone B analog, is a microtubule stabilizing agent which has shown activity in several different tumor types and preclinical models in melanoma. In an open label, one-arm, multi-center phase II trial the efficacy and toxicity of this epothilone was investigated in two different cohorts: chemotherapy-naïve (previously untreated and previously treated patients with metastatic melanoma.Eligible patients had histologically-confirmed stage IV melanoma, with an ECOG performance status of 0 to 2. Ixabepilone was administered at a dose of 20 mg/m(2 on days 1, 8, and 15 during each 28-day cycle. The primary endpoint was response rate (RR; secondary endpoints were time to progression (TTP and toxicity. Twenty-four patients were enrolled and 23 were evaluable for response. Initial serum lactate dehydrogenase (LDH levels were elevated in 6/11 (55% of the previously treated and in 5/13 (38% of the previously untreated patients. No complete or partial responses were seen in either cohort. One patient in the previously treated group developed neutropenia and fatal septic shock. Seventeen patients (8 in the previously untreated group and 9 in the previously treated group progressed after 2 cycles, whereas six patients (3 in each group had stable disease after 2-6 cycles. Median TTP was 1.74 months in the previously untreated group (95% CI = 1.51 months, upper limit not estimated and 1.54 months in the previously treated group (95% CI = 1.15 months, 2.72 months. Grade 3 and/or 4 toxicities occurred in 5/11 (45% of previously untreated and in 5/13 (38% of previously treated patients and included neutropenia, peripheral neuropathy, fatigue, diarrhea, and dyspnea.Ixabepilone has no meaningful activity in either chemotherapy-naïve (previously untreated or previously treated patients with metastatic melanoma. Further investigation with ixabepilone as single agent in the treatment of melanoma is not warranted.Clinical Trials.gov NCT

    BRAF inhibitors improve progression-free and overall survival in patients with metastatic melanoma. Brain metastases are common, and stereotactic radiosurgery (SRS) has been used, resulting in excellent local control. Because BRAF inhibitors are associated with intracranial responses, the authors hypothesized that BRAF inhibitors would improve local control in patients with melanoma who are receiving SRS for brain metastases. The authors retrospectively identified patients with metastatic melanoma who had been tested for BRAF mutation and treated with SRS for brain metastases. Patients with previous resection, multiple brain metastases, or multiple courses of SRS were eligible. SRS was delivered in a single fraction to a median dose of 2000 cGy. Patients with a BRAF mutation were treated with a BRAF inhibitor on the basis of physician preference. The authors identified 52 patients who were treated in 82 treatment sessions for 185 brain metastases and 13 tumor beds. At a median follow-up of 10.5 months, the 1-year local control rate was 69.2%. At 1 year, the local control rate for brain metastases in patients with BRAF mutation with BRAF treatment was 85.0%, and the local control rate for brain metastases in those without BRAF treatment was 51.5% (p = 0.0077). The rates of distant brain failure, freedom from whole-brain radiation, and overall survival were not different on the basis of BRAF mutation status or inhibitor therapy. The number of new intratumoral hemorrhages after SRS was increased significantly in patients with BRAF treatment. Treatment with BRAF inhibitors was associated with improved local control after SRS in patients with melanoma and brain metastases. An increased number of intratumoral hemorrhages was associated with BRAF inhibitor therapy.

    Patients undergoing enucleation for uveal melanoma need to be informed of the possibility of phantom eye syndrome (PES). The number with uveal melanoma in PES studies has been small. Aims were to: (1) determine the prevalence, symptoms, and characteristics of PES and to test associations of PES symptoms with sociodemographic and clinical characteristics; (2) examine the interrelatedness of PES symptoms; and (3) explore the emotional valence of PES and the relationship to anxiety and depression. Cross-sectional questionnaire. Patients (n = 179) with uveal melanoma enucleated 4 to 52 months previously. Questionnaire on PES. Responses to a routine audit of mood obtained from clinical records. Patients were asked about 3 symptoms: pain, visual sensations, and a feeling of seeing through the removed eye. Mood was assessed by the Hospital Anxiety and Depression Scale. Of 179 respondents, 108 (60.3%) experienced symptoms: 86 reported (48%) visual sensations, 50 reported (28%) seeing, and 42 reported (23%) pain; 14 (7.8%) reported all 3 symptoms. At the time of the questionnaire, 31 (17%) experienced 1 or more symptoms daily. Women were more likely to report pain (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.08-4.40). Younger patients at enucleation were more likely to report pain (t = 4.13; degrees of freedom (df), 177; P < 0.001) and visual sensations (t = 2.11; df, 177; P < 0.05). Patients studied sooner after enucleation were more likely to report seeing (Mann-Whitney U, 2343; P < 0.05). Pain and seeing were intercorrelated (chi-square, 5.47; Φ = 0.18; df, 1; P < 0.05), pain with visual sensations (chi-square, 3.91; Φ = 0.15; df, 1; P < 0.05) and seeing with visual sensations (chi-square, 34.22; Φ = 0.45; df, 1; P < 0.001). Twenty of 108 patients (18.5%) found symptoms disturbing, and 21 of 108 (19.4%) pleasurable. Patients reporting pain were more anxious (OR, 3.53; 95% CI, 1.38-9.03) and depressed (OR, 13.26; 95% CI, 3.87-46.21). Patients should be

    INTRODUCTION: The incidence of cutaneous melanoma is increasing in Denmark and worldwide. However, the prevalence of distant metastases at the time of diagnosis has decreased to 1%. We therefore questioned the value of routine preoperative chest X-ray (CXR) for staging asymptomatic melanoma...... patients and hypothesised that routine CXR is not justified. METHODS: A retrospective study was conducted on patients undergoing wide local excision and sentinel lymph node biopsy for cutaneous melanoma in the period from 2010 to 2014. RESULTS: A total of 603 patients were included. The mean time of follow...... value was 8%, and the negative predictive value was 100%. CONCLUSION: Our results suggest that CXR cannot be justified in the initial staging of cutaneous melanoma patients. The guideline for the treatment of melanoma in Denmark is under revision: The use of CXR has been omitted. FUNDING: This study...

  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. [Orbital Exenteration in Patient with Metastatic Choroidal Melanoma - a Case Report].

    Justusová, P; Štubňa, M; Veselovský, M; Lipková, B

    Uveal melanoma is the most common primary intraocular tumour in adults in Caucasians and in 75% is arising from choroid. It threatens not only the patients loss of vision and eye, but also 50% of patients after 5-year interval after therapy die due to distant metastases. The treatment of small and medium-sized melanoma are methods preserving eye globe. Almost half of the total number of patients is still unavoidable enucleation. Considerably rarer is indicated exenteration of an orbit. These tumors metastasize only hematogenous, while the most frequent place of localization of distant metastases is the liver. Generalized disease prognosis is poor, and our current treatment options in this stage are ineffective. Case report of 59 years old patient with choroidal melanoma stage T4 N1 M1 massively infiltrating the orbit. At the time of diagnosis of the primary tumor distant metastases were present. The patient underwent exenteration of the orbit and systemic chemotherapy. Although choroidal melanomas with extrascleral extension and infiltration into the orbit have no better prognosis after exenteration of the orbit, surgery is providing us local tumour control. Good cosmetic effect after this mutilating procedure is offered by individually made prosthesis (epithesis). All patients with uveal melanoma require lifelong dispensation, distant metastases may occur even after many years. In the treatment of generalized disease is available systemic chemotherapy and immunotherapy only palliative. The best effect on survival has complete surgical resection of single metastasis. Uveal melanoma has a different genetic profile as cutaneous melanoma. The biological nature of uveal melanoma seems to be the key to determining risk patients, as well as the development of targeted systemic therapy. Treatment of patients with generalized large uveal melanoma with extrascleral extension is difficult. A better understanding of biological interest may be the key to the detection of

    The cloning of the genes encoding cancer antigens has opened new possibilities for the treatment of patients with cancer. In this study, immunodominant peptides from the gp100 melanoma-associated antigen were identified, and a synthetic peptide, designed to increase binding to HLA-A2 molecules, was used as a cancer vaccine to treat patients with metastatic melanoma. On the basis of immunologic assays, 91% of patients could be successfully immunized with this synthetic peptide, and 13 of 31 patients (42%) receiving the peptide vaccine plus IL-2 had objective cancer responses, and four additional patients had mixed or minor responses. Synthetic peptide vaccines based on the genes encoding cancer antigens hold promise for the development of novel cancer immunotherapies. PMID:9500606

    Purpose: To investigate, in the treatment of uveal melanomas, how tumor control, radiation toxicity, and visual outcomes are affected by the radiation dose at the tumor apex. Methods and Materials: A retrospective review was performed to evaluate patients treated for uveal melanoma with {sup 125}I plaques between 1988 and 2010. Radiation dose is reported as dose to tumor apex and dose to 5 mm. Primary endpoints included time to local failure, distant failure, and death. Secondary endpoints included eye preservation, visual acuity, and radiation-related complications. Univariate and multivariate analyses were performed to determine associations between radiation dose and the endpoint variables. Results: One hundred ninety patients with sufficient data to evaluate the endpoints were included. The 5-year local control rate was 91%. The 5-year distant metastases rate was 10%. The 5-year overall survival rate was 84%. There were no differences in outcome (local control, distant metastases, overall survival) when dose was stratified by apex dose quartile (<69 Gy, 69-81 Gy, 81-89 Gy, >89 Gy). However, increasing apex dose and dose to 5-mm depth were correlated with greater visual acuity loss (P=.02, P=.0006), worse final visual acuity (P=.02, P<.0001), and radiation complications (P<.0001, P=.0009). In addition, enucleation rates were worse with increasing quartiles of dose to 5 mm (P=.0001). Conclusions: Doses at least as low as 69 Gy prescribed to the tumor apex achieve rates of local control, distant metastasis–free survival, and overall survival that are similar to radiation doses of 85 Gy to the tumor apex, but with improved visual outcomes.

    Overexpression of PD-L1 has been shown to be associated with better clinical responses to PD-1/PD-L1 blockade in melanoma. However, the utility of PD-L1 immunostaining as a predictive biomarker for anti-PD-1 treatment remains unclear, especially in melanoma of acral/mucosal origin. Materials and methods We collected and reviewed the medical records of 37 patients with metastatic melanoma who were treated with the anti-PD-1 antibodies pembrolizumab or nivolumab between January and December 2015. Patients with histologically diagnosed malignant melanoma and whose pretreatment tumor specimens were available for immunohistochemical staining of PD-L1 expression in tumor or immune cells were included. Results Of 37 patients, 26 patients had either acral or mucosal melanoma. The overall response rate was 10.8 % (95 % CI, 0.8-20.8 %). The response rate to PD-1 inhibitor was 11.5 % (95 % CI, 0-23.8 %) in acral/mucosal melanoma and that for cutaneous melanoma was 9.1 % (95 % CI, 0-26.1 %). Of these 37 patients, 18 had pre-treatment tumor specimens available for PD-L1 staining. Of 18 patients, 10 (55.5 %) were of acral/mucosal origin. In all patients with acral melanoma, the overall response rate (ORR) was 16.7 % (1 of 6 patients) and disease control rate (DCR) was 50 % (3 of 6 patients). In the PDL-1(+) melanoma group (1 % cut-off value), ORR was 20 % (2/10) and DCR was 80 %; for PDL-1 (-) group, ORR was 12.5 % (1/8) and DCR of 37.5 %. In the PDL-1 (+) group by 5 % cut-off value, ORR was 33.3 % (2/6) and DCR was 83.3 %; for patients with PDL-1 (-), ORR was 8.3 % (1/12) and DCR was 50 %. The median PFS was 6.8 months in PDL-1(+) group and 1.9 months in PDL-1(-) group (p = 0.149). Anti-PD-1 treatment was very well tolerated without serious adverse events of grade 3 or 4 in all patients. Conclusions The treatment outcome to PD-1 antibody was not different in acral/mucosal melanoma when compared with cutaneous melanoma. The immunohistochemical PD-L1

    Full Text Available 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.

    2015-09-01

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

    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.

    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 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.

    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

    Approximately 50% of metastatic melanoma patients harbor BRAF mutations. Several treatment options including the combination of BRAF and MEK inhibitors (BRAF/MEKi) and immunotherapy (mainly anti CTLA-4 and anti PD-1 antibodies), have been shown to improve survival in these patients. Although preclinical data support the synergistic effect of both modalities in combination, data confirming the activity and tolerability of these combinations are not yet available in the clinical setting. Herein, we report the case of a melanoma patient treated with sequential BRAF/MEKi (dabrafenib plus trametinib) followed by the anti CTLA-4 antibody ipilimumab who achieved a pathological complete response. Unfortunately, the patient died due to fatal gastrointestinal (GI) toxicity. Analysis of the BRAFV600E mutation in circulating tumoral DNA (ctDNA) from peripheral blood samples and serial tumor tissue biopsies throughout treatment demonstrated a good correlation with clinical evolution.

    We present our experience of therapeutic vaccination using dendritic cells (DC) pulsed with autologous tumor antigens in patients with advanced melanoma. Twenty-one pretreated advanced melanoma patients were vaccinated with autologous DC pulsed with 100 microg/ml of autologous-tumor-lysate (ATL) or -homogenate (ATH) and 50 microg/ml of keyhole limpet hemocyanin (KLH). The first 8 patients were treated subcutaneously or intradermally with immature-DC (iDC) (range 4.5-82 x 10(6)) and the remaining 13 intradermally with in vitro matured DC (mDC) (range 1.2-26 x 10(6)). Subcutaneous interleukin-2 (3 x 10(6) IU) was administered from days 3 to 7 of each treatment cycle. 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).

    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.

    Studies of human cancer metastasis have been limited by a lack of experimental assays in which cancer cells from patients metastasize in vivo in a way that correlates with clinical outcome. This makes it impossible to study intrinsic differences in the metastatic properties of cancers from different patients. We recently developed an assay in which human melanomas readily engraft in nonobese diabetic/severe combined immunodeficient interleukin-2 receptor-γ chain null (NSG) mice. We show that melanomas from 25 patients exhibited reproducible differences in the rate of spontaneous metastasis after transplantation into NSG mice and that these differences correlated with clinical outcome in the patients. Stage IIIB/C melanomas that formed distant metastases within 22 months in patients also formed tumors that metastasized widely in NSG mice, whereas stage IIIB/C melanomas that did not form distant metastases within 22 to 50 months in patients metastasized more slowly in NSG mice. These differences in the efficiency of metastasis correlated with the presence of circulating melanoma cells in the blood of NSG mice, suggesting that the rate of entry into the blood is one factor that limits the rate of metastasis. The study of NSG mice can therefore yield information about the metastasis of human melanomas in vivo, in this case revealing intrinsic differences among stage III melanomas in their ability to circulate/survive in the blood and to metastasize.

    Cutaneous melanoma is the most aggressive form of skin cancer. With age as a risk factor, melanoma is projected to become a substantial healthcare burden. The clinical course of melanoma in older patients is different from that in middle-aged and younger patients: melanomas are thicker, have higher mitotic rates and are more likely to be ulcerated. Older patients also have a higher mortality rate, yet, paradoxically, have a lower rate of lymph node metastases. After decades of no significant progress in the treatment of this devastating disease, novel insights into the mechanisms underlying the pathophysiology of metastatic melanoma have led to new and remarkably efficient therapeutic opportunities. The discovery that about half of all melanomas carry BRAF mutations led to the introduction of targeted therapy with significant improvements in clinical outcomes. Although these drugs appear to be equally effective in older patients, specific considerations regarding adverse events are required. Besides targeted therapy, immunotherapy has emerged as an alternative therapeutic option. Antibodies that block cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1) can induce responses with high durability. Despite an aging immune system, older patients seem to benefit to the same degree from these treatments, apparently without increased toxicity. In this review, we focus on the epidemiology, clinicopathological features, and recent developments of systemic treatment in cutaneous melanoma with regard to older patients.

    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.

    Laser immunotherapy (LIT) has shown great promise in pre-clinical studies and preliminary clinical trials. It could not only eradicate treated local tumors but also cause regression and elimination of untreated metastases at distant sites. Combining a selective photothermal therapy with an active immunological stimulation, LIT can induce systemic anti-tumor immune responses. Imiquimod (IMQ), a toll-like receptor agonist, was used for the treatment of late-stage melanoma patients and glycated chitosan (GC), a biological immunological modulator, was used for the treatment of late-stage breast cancer patients, in combination of irradiation of a near-infrared laser light. To observe the immunological changes before and after LIT treatment, the pathological tissues of melanoma and breast cancer patients were processed for immunohistochemical analysis. Our results show that LIT changed the expressions of several crucial T cell types. Specifically, we observed significant decreases of CD3+ T-cells and a significant increase of CD4+,CD8+, and CD68+ T-cells in the tumor samples after LIT treatment. While not conclusive, our study could shed light on one the possible mechanisms of anti-tumor immune responses induced by LIT. Further studies will be conducted to identify immunological biomarkers associated with LIT-induced clinical response.

    The presence of psychological distress has a negative impact not only on cancer patients' quality of life but also on the course of the disease, with slower recovery and increased morbidity. These issues are of particular importance in melanoma patients (MP), who remain at risk of disease progression for many years after diagnosis. This study aimed to investigate psychological distress, coping strategies, and their possible relationships with demographic-clinical features in patients with early-stage melanoma in follow-up. The investigation focused in particular on whether the psychological profile differed between patients at different melanoma stages. Data of 118 patients with melanoma in the Tis-Ia stages (MP_Tis-Ia) and 86 patients with melanoma in the Ib-IIa-IIb stages (MP_Ib-II) were gathered through a self-administered survey and compared using a cross-sectional design. The results evidenced a high percentage of anxiety (25%) and distress symptoms (44%), whereas depressive symptoms seemed less frequent (8%). Psychological distress was higher in women than in men, and in patients with a higher educational level. Nevertheless, no significant differences were found between MP_Tis-Ia and MP_Ib-II. With respect to coping style, the patients in this sample adopted predominantly positive and active strategies. Correlational analyses showed that maladaptive coping strategies such as behavioral disengagement, denial, self-distraction, and self-blame were most strongly related to increased levels of psychological distress. The high presence of anxiety and distress symptoms, their relationship, and the use of negative coping strategies underline the importance of psychological distress screening also in early-stage MP, including at long-term follow-up.

    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

    Conclusion: The anatomical distribution of MIS differed with patient age and tumour subtype. The anatomical distribution was different in comparison to invasive malignant melanomas, and MIS cases were generally older. This suggests a non-linear relation between malignant melanoma in situ and invasive malignant melanoma.

    The purpose of this study was to report the clinical outcomes of patients with conjunctival melanoma treated with interferon (IFN) α-2b eye drops following local tumor resection. Five eyes of five patients were enrolled in this study. All patients underwent the local resection of tumors, and topical IFNα-2b eye drops were subsequently administered 4 times/day until the complete disappearance of the pigmented lesions determined by slit-lamp examination. Ophthalmological findings, histopathological findings, and imaging modalities were retrospectively analyzed. The age of the patients ranged from 65 to 84 years (mean: 75.4 years). Locations of the tumor were the bulbar conjunctiva in three eyes, multiple palpebral conjunctivas in one eye, and palpebral conjunctiva and caruncle in one eye. All patients received topical IFNα-2b eye drop treatment for 6-10 months. Follow-up periods after resection ranged from 18 to 78 months. Histologically, all excised conjunctival tumors were diagnosed with malignant melanoma, where the surgical margins were completely negative in one patient. No patients had suffered from severe adverse effects related to IFNα-2b. Four out of five patients consequently achieved complete remission. Since one eye in one case showed resistance to the local chemotherapy containing IFNα-2b eye drops and the subconjunctival injection of IFN-β, orbital exenteration was eventually required 12 months after local resection. Topical IFNα-2b eye drops may be safe and one of the useful adjunctive treatments following surgical resection for patients with conjunctival melanoma.

    The authors' interest was focused on prolactin status in patients with melanocytic lesions and on changes induced by interferon treatment in melanoma patients. The study lasted 5 years and included 128 melanoma patients, 48 dysplastic nevi patients and 48 healthy volunteers. Sixty melanoma cases were selected after surgical removal of tumor and divided into 2 groups: 30 patients with 10 MUmp(-1) interferon alpha2b treatment, three times a week, one year and 30 patients without interferon treatment. Prolactin assessment was made at inclusion in the study, after surgical removal of tumor, when patients started the treatment, after 1, 6, 12 months of treatment and 6 months after treatment end. In melanoma patients, high values of prolactin (10.55 ± 5.94 ng/ml) were detected when compared with dysplastic nevi group (5.94 ± 2.87 ng/ml) and control group (5.74 ± 3.66 ng.ml). Prolactin levels decreased after surgical removal of melanoma, significantly increased during interferon treatment and returned to baseline few months after the immunomodulatory treatment. The treatment with interferon alpha2b stimulated reversible and non-cumulative prolactin production. Evaluating prolactin in melanoma patients could become necessary in the future, both for finding a possible pituitary disorder, but also for a new pharmacological intervention.

    Malignant melanoma (MM) is the cutaneous neoplasia with the greatest mortality rates and one of the malignancies with the highest potential of dissemination. The prognosis of patients with metastatic MM is grim, with a 5-years survival rate between 5-19%, and is dictated by the location and the number of metastases. We aimed to estimate the survival of patients with metastatic MM from our study and find out if the metastasis' location influences survival. Between 2008 and 2013, 155 patients with cutaneous MM were diagnosed in our clinic. All the patients were staged according to 2009 AJCC staging system. The median follow-up period was of 24 months. Survival was calculated by using the Kaplan-Meier method with a confidence level of 95%. 40.5% of the patients developed metastases in different organs, especially the brain. 80.6% of those with metastases died during the study. The median overall survival, estimated for the entire group of patients who developed metastases, was of 5.3 months. The influence of metastases distribution on the overall survival was examined and it was noticed that there were statistically significant differences between the risks of death of various groups of patients, depending on metastasis topography. Thus, the death probability of a patient with brain metastases is twice that of a patient with digestive metastasis, about 7 times higher than that of a patient with lung metastasis (p=0.0004) and 12 times higher than the death risk of a patient with extra-regional lymph nodes or subcutaneous metastasis (p=0.0000).

    Abstract Recent advances in melanoma therapy have influenced the management of metastatic patients. Inhibitors of the BRAF/MEK/ERK signaling cascade have been proven highly effective in the metastatic disease although displaying different side effects. Here, we report a patient with BRAF V600E-mutated stage IV melanoma who developed a severe leukopenia upon targeted therapy with the BRAF inhibitor vemurafenib. Interestingly, the immediate therapeutic switch to a different BRAF inhibitor ‘dabrafenib́ had no negative influence on the leukocyte count. This case supports recent studies, which showed a differential influence of different BRAF inhibitors on patients’ leukocytes despite similar clinical efficacy in melanoma. PMID:25526431

    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.

    Full Text Available Abstract Background Th17 cells are CD4+ cells that produce interleukin 17 (IL-17 and are potent inducers of tissue inflammation and autoimmunity. We studied the levels of this T cell subset in peripheral blood of patients treated with the anti-CTLA4 antibody tremelimumab since its major dose limiting toxicities are inflammatory and autoimmune in nature. Methods Peripheral blood mononuclear cells (PBMC were collected before and after receiving tremelimumab within two clinical trials, one with tremelimumab alone (21 patients and another together with autologous dendritic cells (DC pulsed with the melanoma epitope MART-126–35 (6 patients. Cytokines were quantified directly in plasma from patients and after in vitro stimulation of PBMC. We also quantified IL-17 cytokine-producing cells by intracellular cytokine staining (ICS. Results There were no significant changes in 13 assayed cytokines, including IL-17, when analyzing plasma samples obtained from patients before and after administration of tremelimumab. However, when PBMC were activated in vitro, IL-17 cytokine in cell culture supernatant and Th17 cells, detected as IL-17-producing CD4 cells by ICS, significantly increased in post-dosing samples. There were no differences in the levels of Th17 cells between patients with or without an objective tumor response, but samples from patients with inflammatory and autoimmune toxicities during the first cycle of therapy had a significant increase in Th17 cells. Conclusion The anti-CTLA4 blocking antibody tremelimumab increases Th17 cells in peripheral blood of patients with metastatic melanoma. The relation between increases in Th17 cells and severe autoimmune toxicity after CTLA4 blockade may provide insights into the pathogenesis of anti-CTLA4-induced toxicities.

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.

    CONCLUSIONS: 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 considered as a matter of dispute for some experts. Once again, by a clinical case and the following analysis, we would like to focus the attention of the dermatosurgical community on this crucial and highly significant problem. Innovations are very often resulting from the simplicity of logic, which unfortunately is not always accepted appropriately.

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

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

    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%. Non-cuSCC was observed in 3 patients (0.1%; 2.5 per 1000 PY) at 3 sites: bronchi, heart and lung. CuSCC and non-cuSCC were

    MC1R sequence variants are associated with malignant melanoma risk, and most commonly are missense mutations. Few (n=9) truncating mutations have been described in this gene as predisposing to malignant melanoma. In this study, three Jewish individuals were found to harbor an identical truncating MC1R mutation--Y152X: an Ashkenazi patient with two malignant melanomas, a non-Ashkenazi malignant melanoma patient with familial malignant melanoma and her asymptomatic mother. Both malignant melanoma patients carried additional, seemingly pathogenic MC1R variants. Haplotype analysis revealed that all three mutation carriers shared the same haplotype. This sequence variant was previously described in ethnically diverse, non-Jewish individuals and in all likelihood represents an error-prone domain that, in conjunction with other genetic and environmental factors, increases malignant melanoma risk.

    ALCAM (activated leukocyte cell adhesion molecule, CD166, MEMD) is a transmembrane protein of immunoglobulin superfamily (Ig-SF) and plays an important role in human malignant melanoma progression and formation of locoregional and distant metastases. The study using melanoma cell lines showed that overexpression of ALCAM is directly related with the increase of cytoaggregation and the ability to form cell nests. The aim of the study was to assess the expression and intracellular localization of ALCAM in primary skin melanomas and metastatic lesions from regional lymph nodes. Also, prognostic significance of ALCAM expression in primary tumor cells and metastatic lesion cells was evaluated in the context of 5-year observation. Formalin-fixed paraffin-embedded tissue specimens from 104 primary cutaneous melanomas and 16 regional lymph nodes metastases were studied for the expression of ALCAM measured by immunohistochemistry. We demonstrate that high ALCAM expression in primary melanoma cells (IRS ≥8) is strongly correlated with unfavorable prognosis as compared with patients with lower ALCAM immunoreactivity in tumor compartment as regards cancer specific overall survival (CSOS) (P = 0.001) and disease free survival (DFS) (P melanoma invasion in the primary tumor according to Clark scale (P = 0.032). It was also found that decreased ALCAM expression (IRS melanoma cells of the primary tumor can be used as a marker of negative outcome and may indicate a more invasive phenotype of cancer cells, which would require a more intensive therapeutic strategy. Low expression of ALCAM in regional lymph node metastases is a feature associated with unfavorable prognosis in patients with cutaneous melanoma. Our study is the first one to evaluate the effect of increased ALCAM expression on long-term survival in melanoma patients.

    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.

    Sentinel lymph nodes (SLN) in popliteal basins are rare, and there is controversy in literature regarding their origin, management, and outcomes. To correlate clinical and pathological features of popliteal basin drainage and analyze the impact of popliteal lymph node drainage on survival. Retrospective analysis of SLN biopsies performed at a single institution between 2000 and 2010. SLN biopsies were performed in 254 patients with melanoma in lower limbs, 247 of which were evaluated. In this group, there were 59 patients (24%) with a positive SLN. Twenty-seven cases (11%) presented with popliteal drainage, one of which lacked concurrent groin drainage. Among these 27 patients, three (11%) had popliteal metastasis, one of which had exclusive involvement of this basin. Popliteal drainage was associated with worse 5-year disease-free survival (DFS) (P = 0.028) but not 5-year overall survival (OS) (P = 0.219) in univariate analysis. In multivariate analysis, Breslow thickness, mitotic index, and positive SLN were prognostic factors for DFS. Only mitotic index correlated significantly with OS (P = 0.044). Popliteal drainage seems to be associated with worse prognostic features of the primary tumor. © 2015 Wiley Periodicals, Inc.

    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.

    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.

    Heat shock proteins (hsps) have been studied in numerous cancer types, but a clear view of their clinical relevance in melanoma remains elusive. Therefore, the aim of this study was to investigate the expression of hsps in melanoma with respect to patient clinical parameters. Using Western immunoblotting, hsps 90, 70, 60, 40 and 32 were observed to be widely expressed in metastatic melanomas (n = 31), while immunofluorescence demonstrated that in the majority of samples these hsps, apart from hsp32, were increased in expression in melanoma cells compared with surrounding non-melanoma cells in situ (n = 8). Correlating hsp expression with patient clinical parameters indicated that greater hsp90 (P < 0.02) and hsp40 (P < 0.03) expression correlated with advanced stage (stage III Vs stage IV), while in the case of hsp40, this was additionally associated with reduced patient survival (P < 0.05). In contrast, higher hsp32 expression was associated with improved patient survival (P < 0.007). On the other hand, the expression of the other hsps did not correlate with any obtainable patient clinical parameters. This study provides further evidence for the importance of hsps in melanoma and for their use as therapeutic targets and biomarkers, but larger-scale follow-up studies are required to confirm these results.

    BRAF was identified as an oncogene in skin melanoma in 2002, and since 2011 has been a therapeutic target in the treatment of metastatic melanoma. The role of BRAF mutation in tumour initiation and the disease course remains to be elucidated. The main objective of our study was to determine whether there is a relationship between BRAF status and overall survival in patients with a melanoma and a positive sentinel lymph node. We also sought an association between BRAF status and the clinicopathological features of the melanoma. Finally, we looked for a potential heterogeneity of BRAF status in primary and metastatic tumours. All patients (n = 72) treated for melanoma and with a positive sentinel lymph node at the University Hospital of Clermont-Ferrand, France, between January 2000 and January 2010 were enrolled in the study. We investigated BRAF status in primary melanoma and lymph node metastatic tissue in our molecular pathology laboratory and collected the clinical and survival data. Of the 72 patients, 32 had at least one BRAF mutation. There was a statistically significant difference in overall survival between the BRAF-mutated and wild-type populations. The only clinical feature related to BRAF status was metastatic burden. Of the 25 patients in whom we obtained the status in both locations, five had a discordant result. BRAF mutation is an indicator of poor prognosis in patients with stage III melanoma with a positive sentinel lymph node. BRAF status could be used in the staging of this population. BRAF has a role not only in cellular immortalization but also in metastatic spread. © 2014 British Association of Dermatologists.

    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

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.

    Completion lymph node dissection (CLND) following positive sentinel node biopsy (SNB) for melanoma detects additional nonsentinel node (NSN) metastases in approximately 20% of cases. This study aimed to establish whether NSN status can be predicted, to determine its effect on survival, and to develop survival tree models for the sentinel node (SN) positive population. Sydney Melanoma Unit (SMU) patients with at least 1 positive SN, meeting inclusion criteria and treated between October 1992 and June 2005, were identified from the Unit database. Survival characteristics, potential predictors of survival, and NSN status were assessed using the Kaplan-Meier method, Cox regression model, and logistic regression analyses, respectively. Classification tree analysis was performed to identify groups with distinctly different survival characteristics. A total of 323 SN-positive melanoma patients met the inclusion criteria. On multivariate analysis, age, gender, primary tumor thickness, mitotic rate, number of positive NSNs, or total number of positive nodes were statistically significant predictors of survival. NSN metastasis, found at CLND in 19% of patients, was only predicted to a statistically significant degree by ulceration. Multivariate analyses demonstrated that survival was more closely related to number of positive NSNs than total number of positive nodes. Classification tree analysis revealed 4 prognostically distinct survival groups. Patients with NSN metastases could not be reliably identified prior to CLND. Prognosis following CLND was more closely related to number of positive NSNs than total number of positive nodes. Classification tree analysis defined distinctly different survival groups more accurately than use of single-factor analysis.

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.

    Controversial data have been reported about HLA alleles and susceptibility to melanoma. Our investigation was undertaken to analyze the relationship between HLA alleles distribution in patients with melanoma and susceptibility to the tumor, in order to study the possible correlation between HLA class II DQA1, DQB1 and DRB1 genes involved in immune recognition, and melanoma, usually considered a highly immunogenic tumor. We therefore typed by means of PCR-SSP (sequence-specific primers) 53 Italian patients and 53 healthy random controls coming from the same geographic area. We observed a decrease of all haplotypes bearing DQB1*0301, DQB1*0302 and DQB1*0303 alleles but not of haplotype DRB1*11;DQA1*0501;DQB1*0301. Our results seem to support the hypothesis of a protective role of some DQ3-bearing haplotypic combinations in melanoma.

    Full Text Available Abstract Background High-dose interferon-alpha 2b (IFN-α 2b is the only approved systemic therapy in the United States for the adjuvant treatment of melanoma. The study objective was to explore the immunomodulatory mechanism of action for IFN-α 2b by measuring serum regulatory T cell (Treg, serum transforming growth factor-β (TGF-β, interleukin (IL-10, and autoantibody levels in patients with melanoma treated with the induction phase of the high-dose IFN-α 2b regimen. Methods Patients with melanoma received IFN-α 2b administered intravenously (20 MU/m2 each day from day 1 to day 5 for 4 consecutive weeks. Serum Treg levels were measured as whole lymphocytes in CD4+ cells using flow cytometry while TGF-β, IL-10, and autoantibody levels were measured using enzyme-linked immunosorbent assays. Results Twenty-two patients with melanoma received IFN-α 2b treatment and were evaluated for Treg levels. Before treatment, Treg levels were significantly higher in patients with melanoma when compared with data from 20 healthy subjects (P = 0.001; Mann-Whitney test. Although a trend for reduction of Treg levels following IFN-α 2b treatment was observed (average decrease 0.29% per week, statistical significance was not achieved. Subgroup analyses indicated higher baseline Treg levels for stage III versus IV disease (P = 0.082, early recurrence versus no recurrence (P = 0.017, deceased versus surviving patients (P = 0.021, and preoperative neoadjuvant versus postoperative adjuvant treatment groups (not significant. No significant effects were observed on the levels of TGF-β, IL-10, and autoantibodies in patients with melanoma treated with IFN-α 2b. Conclusions Patients with melanoma in this study showed increased basal levels of Treg that may be relevant to their disease and its progression. Treg levels shifted in patients with melanoma treated with IFN-α 2b, although no firm conclusions regarding the role of Tregs as a marker of treatment response

    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.

    . In this study it is investigated whether FDG-PET might add information on the efficacy of immune therapy. MATERIALS AND METHODS: In a retrospective analysis data from patients with advanced progressive melanoma, treated with DC vaccinations and evaluated by PET/CT scans at baseline as well as after 6...... vaccinations were analysed. If a patient achieved stable disease according to RECIST, additional vaccinations were given. The PET scans were evaluated according to EORTC guidelines. RESULTS: PET/CT scans from 13 patients were evaluated. According to RECIST 3 patients achieved stable disease and 10 patients...... PET scans to the CT evaluation of patients treated with DC vaccines, a more detailed picture of the single lesions was found. This seems to improve the clinical evaluation of the treatment. The lack of correlation between the PET and CT scans suggests that some of the increases in target lesions seen...

    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.

  2. Thin melanoma.

    The incidence of malignant melanoma is increasing and a preponderance of the melanomas diagnosed today are "thin in terms of Breslow criteria. Although thin melanomas, as a group, are associated with a very good prognosis, a subset of these tumors may metastasize and cause death. These cases can be identified by using prognostic models, including the "standard" American Joint Committee on Cancer criteria, and other attributes identified in follow-up studies. To review the history of concepts of prognostic modeling in melanoma, focusing on thin melanomas. Selected literature. About 40 years ago, it was realized that malignant melanoma, once almost uniformly fatal, could be divided into categories with better or worse prognosis through the use of prognostic models. The first simple models, Clark levels of invasion and Breslow thickness, are still in use. Thickness remains the single most useful variable. Breslow recognized that melanomas less than 0.76 mm in thickness were associated with a very good prognosis, with no metastases in his limited initial study. The American Joint Committee on Cancer selected a cutoff of 1.0 mm, which achieves a similar result, with stage modifiers, although some metastases and deaths do occur with stage I lesions. Clark demonstrated an almost equally good prognosis for his level II invasive melanomas and recognized that most of these lesions, although invasive, lacked the ability to form tumors or to undergo mitosis in the dermis and were therefore "nontumorigenic" and "nonmitogenic" and lacked competence for metastasis. Studies of these low-risk melanomas have led to the development of criteria for earlier diagnosis and a steady, but still inadequate, improvement in prognosis for melanoma overall. Multivariable models currently can identify groups of patients within the "thin melanoma" category whose prognosis varies, from a disease-free survival of close to 100% to about 70%. Prognosis declines more or less linearly with increasing

    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

    Features associated with an increased frequency of cyclin-dependent kinase inhibitor 2A (CDKN2A) mutations have been identified in families with 3 or more patients with cutaneous melanoma (CM). However, in families with 2 patients with CM, which represent the majority of familial melanoma, these factors have been rarely studied. We investigated association of 3 clinical features with the presence of a CDKN2A mutation in a family by extent of CM family clustering (2 vs ≥3 patients with CM among first-degree relatives in a family). We included 483 French families that comprised 387 families with 2 patients with CM (F2 families) and 96 families with 3 or more patients with CM (F3+ families). Three clinical factors were examined individually and in a joint analysis: median age at diagnosis younger than 50 years, and 1 or more patient in a family with multiple primary melanoma or with pancreatic cancer. The frequency of CDKN2A mutations was higher in F3+ families (32%) than in F2 families (13%). Although early age at melanoma diagnosis and occurrence of multiple primary melanoma in 1 or more patient were significantly associated with the risk of a CDKN2A mutation in F2 families, early age at melanoma diagnosis and occurrence of pancreatic cancer in a family were significantly associated with CDKN2A mutations in F3+ families. The study was not population based. This study shows that factors associated with CDKN2A mutations differ by extent of CM family clustering. It indicates that, in France, families with 2 patients with CM are eligible for genetic testing especially when there is an early age at CM diagnosis and/or 1 or more patients with multiple primary melanoma.

    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.

    The purpose of this study was to determine the survival rate of patients with uveal melanoma and sex disparity in this rate in South Korea. We extracted incident uveal melanoma patients using the Korea Central Cancer Registry (KCCR) database, which covered the entire population from 1999 to 2012 in South Korea. We estimated all-cause survival probabilities and cancer-specific survival probabilities of patients with uveal melanoma and compared these probabilities between subgroups (sex, tumor site, age at diagnosis, etc.) using Kaplan-Meier methods and log-rank tests. We fitted the Cox-proportional hazards models for all-cause death and cancer death to determine sex disparities in survival. A total of 344 uveal melanoma patients (175 women, 51%) were ascertained. They comprised 283 patients with choroidal melanoma (82%) and 61 patients with ciliary body/iris melanoma (18%). The observed 5-year survival probability from all-cause death was 75% (95% confidence interval [CI]: 69%-79%); women with uveal melanoma showed higher survival probability (83% [95% CI: 76%-89%]) compared with men (66% [95% CI: 58%-73%], P women with uveal melanoma were lower than those in men (hazards ratio for cancer death = 0.50 [95% CI: 0.30-0.81]; hazards ratio for all-cause death = 0.39 [95% CI: 0.25-0.61]). Women with uveal melanoma have better survival probabilities relative to men with uveal melanoma. Our findings show a comprehensive picture of survival probability in uveal melanoma cancer patients in Korea, which requires further investigation of mechanism of the sex disparity in uveal melanoma.

    Dabrafenib is a potent BRAF inhibitor, which showed intracranial tumor activity. The purpose of our retrospective analysis was to evaluate the efficacy of dabrafenib for patients with melanoma brain metastasis (BM). We studied 30 BRAF mutant melanoma patients with BM, who received dabrafenib after local control of the brain between 2014 and 2017. Eastern Cooperative Oncology Group Performance Status (ECOG) was 0-2. The control arm consisted of 204 melanoma patients from our institutional melanoma database with BM and ECOG 0-2 treated with local therapies and/or chemotherapy, between 2003 and 2015. We found the intracranial disease control rate (DCR) was 83% including four (13%) complete remissions (CR), nine (30%) partial remissions (PR) and twelve (40%) stable diseases (SD) in contrast to five (17%) progressive diseases (PD). With a median follow-up of 14 months, median progression-free survival (PFS) and overall survival (OS) were 5.5 months, and 8.8 months, respectively. If calculated from BM onset, the OS turned to be 11.8 months on the dabrafenib arm, while it was only 6.0 months in the control arm (HR = 0.45, p = 0.0014). Higher risk of progression was observed with increasing ECOG (HR =4.06, p = 0.00027) and if more than 2 extracranial organs were involved (HR = 3.4, p = 0.0077). Elevated lactate dehydrogenase (LDH) was non-significantly associated with worse clinical outcome. Remarkable intracranial activity of dabrafenib in real practice was confirmed by our analysis.

    To evaluate the efficacy of bevacizumab on reduction of the enucleation rate and control of intraocular pressure (IOP) in neovascular glaucoma (NVG)-complicating proton beam therapy for UM and to identify the determinants of the efficacy of bevacizumab. Retrospective comparative study of patients with rubeosis following proton therapy for uveal melanoma. Patients were divided into two groups: a bevacizumab group and a control group which comprised two subgroups: panretinal photocoagulation (PRP)/cryotherapy and observation subgroups. Bevacizumab was administered by three intravitreal injections at 1-month intervals. A second series of injections was administered when necessary. Data concerning IOP and the secondary enucleation rate were collected and compared between the two groups. Univariate and multivariate analyses were performed to determine predictive factors of response to bevacizumab. A total of 169 patients who developed rubeosis following proton therapy between 2006 and 2016 were included: 44 patients in the bevacizumab group and 125 in the control group (38 in the PRP/cryotherapy subgroup and 87 in the observation subgroup). The two groups presented the same baseline characteristics apart from hypertension, retro-equatorial site, and proximity of the optic disk, which were more frequent in the control group, while initial retinal detachment and larger tumor volume were more frequent in the bevacizumab group. After a mean follow-up of 31 months, IOP was less than 21 mmHg in 54.54% of patients after IVB versus 72.7% before treatment (p = 0.06). Statistical analysis did not reveal any statistically significant reduction of the enucleation rate in the bevacizumab group compared to the observational group, whereas the PRP/cryotherapy group showed better eye retention rate (p = 0.15). No enucleation was performed when IOP was bevacizumab. Despite the improvement of IOP level, intravitreal bevacizumab (IVB) did not reduce the overall enucleation rate in

    Melanoma incidence and mortality rates are increasing worldwide within the white population. Clinical and histological factors have been usually used for the prognosis and assessment of the risk for melanoma. The aim of the study was to describe the clinical and histopathological features of the cutaneous melanoma (CM) in the Latvian population, to test the association between melanoma features and patient survival, and to assess the time trends for melanoma incidence. We undertook a descriptive, retrospective analysis of archive data of 984 melanoma patients treated at the largest oncological hospital of Latvia, Riga East University Hospital Latvian Oncology Centre (LOC), between 1998 and 2008. Cox proportional hazards model was used to analyse patient survival and autoregressive models were applied to detect trends in melanoma incidence over time for various categories of melanoma. The study showed a significant ascending trend in melanoma incidence in Latvia during the time period from 1998 to 2008 (ß = 1.83, 95% CI = 1.15-2.91, P = 0.011). Nodular melanoma was the most common tumour subtype with a frequency of 39.2%. Ulceration was present in 45.2% of melanomas. The mean Breslow thickness was 6.0 mm (6.8 mm) and no significant decline in median Breslow thickness was observed during the study period (P = 0.609). A better overall prognosis was detected for females in comparison with males (HR = 1.49; 95% CI = 1.22-1.81; P Latvia with the majority of melanomas diagnosed at late stages with poor prognosis for survival. © 2012 The Authors Journal of the European Academy of Dermatology and Venereology © 2012 European Academy of Dermatology and Venereology.

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.

    The association of melanoma with HLA class II loci is under extensive debate. Different investigators have found discrepant results due to, at least in part, sample size, patient series heterogeneity, choice of control population and differences in the techniques employed for the detection of HLA antigens and alleles. This study was designed to analyse the possible association of melanoma with HLA class II loci with regard to different clinic pathological factors and to investigate other risk factors for melanoma susceptibility, such as HLA homozygosity. HLA-DRB1, -DQA1 and -DQB1 genotyping was performed for 117 eastern Spanish patients presenting with primary melanoma. Although there were no significant alterations in the phenotypic frequencies of HLA-DQA1, -DQB1 or -DRB1 alleles in any subgroup of patients when compared with controls, patients exhibited a statistically significant increase in HLA-DQA1 homozygosity rate. This DQA1 homozygosity-specific association was particularly dependent on some features in melanoma patients such as light hair colour, skin type I or II, early age at diagnosis, absence of atypical naevi, or abscence of atypical naevus syndrome phenotype (aetiological fractions about 10-20%). Analysis of homozygosity for single DQA1 alleles showed an increased homozygosity rate for DQA1*0505 and DQA1*0301 in comparison with controls. These DQA1 alleles are in strong linkage disequilibrium with DQB1*0301 in white populations, and DQB1*0301 homozygous individuals were significantly increased in red in or fair-haired patients (relative risk 5.65). Our results indicate that the contribution of HLA class II alleles to primary melanoma incidence is not significant in the Spanish population. However, homozygosity for the HLA-DQA1 locus (and, perhaps, for the HLA-DQB1*0301 allele) might be considered a potential risk factor for developing melanoma depending on the person's genetic background and, perhaps, on certain environmental conditions.

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

    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.

    2016-10-01

    Regression is caused by a host immunological response primarily characterized by lymphocytic infiltration directed against melanoma cells. The prognostic significance of regression remains controversial in cutaneous melanoma patients. The aim of this study was to determine the clinical significance of the histological regression status in patients with cutaneous melanoma. A total of 664 patients with a pathologically confirmed cutaneous melanoma were enrolled into this study and were investigated retrospectively. The median age of the patients was 51 years, ranging in age from 16 to 104 years. The majority of them had lesions without regression (n=495; 74.5%) and others had lesions with regression (n=169; 25.5%). Melanoma patients with regression were more frequently males (60.1 vs 51.7%; P=0.038) and had axial localized lesions (67.5 vs 53.7%; P=0.002), superficial spreading histologic subtype (73.2 vs 49.1%; P=0.000), thin Breslow depth (nodular pathology, advanced Clark invasion level (IV-V), thick Breslow depth (≥2 mm), high mitotic rate (>3/mm), ulceration, vertical growth phase, neurotropism, lymphovascular invasion, lymph node involvement, metastasis, and recurrence of disease, and male patients had poor prognostic variables for both relapse-free survival and overall survival. However, the presence of regression was not associated with relapse-free survival (P=0.093) nor overall survival (P=0.113) similar to other factors such as age, tumor localization, tumor-infiltrating lymphocytes, and association with a pre-existing melanocytic nevus. Similar insignificant P values were also observed in multivariate analyses (P=0.115 and 0.816, respectively). In conclusion, the presence of histological regression plays no prognostic role in nodal involvement nor survival in patients with cutaneous melanoma.

    Full Text Available Marcello Arca, Giovanni PignaAtherosclerosis Unit, Department of Internal Medicine and Allied Medical Specialities, Sapienza University of Rome, Rome, ItalyAbstract: Statins are effective in reducing cardiovascular events and are safe for almost all patients. Nevertheless, intolerance to statins is frequently faced in clinical practice. This is mostly due to muscular symptoms (myalgia with or without increase of plasma creatinine kinase and/or elevation of hepatic aminotransferases, which overall constitutes approximately two-thirds of reported adverse events during statin therapy. These side effects raise concerns in patients as well as in doctors and are likely to reduce patients' adherence and, as a consequence, the cardiovascular benefit. Therefore, it is mandatory that clinicians improve their knowledge on the clinical aspects of muscular and hepatic side effects of statin therapy as well as their ability to manage patients with statin intolerance. Besides briefly examining the clinical aspects and the mechanisms that are proposed to be responsible for the most common statin-associated side effects, the main purpose of this article is to review the available approaches to manage statin-intolerant patients. The first step is to determine whether the adverse events are indeed related to statin therapy. If so, lowering the dosage or changing statin, alternate dosing options, or the use of nonstatin compounds may be practical strategies. The cholesterol-lowering potency as well as the usefulness of these different approaches in treating statin-intolerant patients will be examined based on currently available data. However, the cardiovascular benefit of these strategies has not been well established, so their use has to be guided by a careful clinical assessment of each patient.Keywords: statin therapy, atorvastatin, rosuvastatin, aminotransferase levels, myopathy

    Current prognostic clinical and morphological parameters are insufficient to accurately predict metastasis in individual melanoma patients. Several studies have described gene expression signatures to predict survival or metastasis of primary melanoma patients, however the reproducibility among these studies is disappointingly low. We followed extended REMARK/Gould Rothberg criteria to identify gene sets predictive for metastasis in patients with primary cutaneous melanoma. For class comparison, gene expression data from 116 patients with clinical stage I/II (no metastasis) and 72 with III/IV primary melanoma (with metastasis) at time of first diagnosis were used. Significance analysis of microarrays identified the top 50 differentially expressed genes. In an independent data set from a second cohort of 28 primary melanoma patients, these genes were analyzed by multivariate Cox regression analysis and leave-one-out cross validation for association with development of metastatic disease. In a multivariate Cox regression analysis, expression of the genes Ena/vasodilator-stimulated phosphoprotein-like (EVL) and CD24 antigen gave the best predictive value (p = 0.001; p = 0.017, respectively). A multivariate Cox proportional hazards model revealed these genes as a potential independent predictor, which may possibly add (both p = 0.01) to the predictive value of the most important morphological indicator, Breslow depth. Combination of molecular with morphological information may potentially enable an improved prediction of metastasis in primary melanoma patients. A strength of the gene expression set is the small number of genes, which should allow easy reevaluation in independent data sets and adequately designed clinical trials.

    To evaluate the influence of 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, preventing

    Malignant melanoma (MM) is an aggressive disease with a rapidly rising incidence due to neoplasm of melanocytes. Molecular targeted therapies have demonstrated lower toxicity and improved overall survival versus conventional therapies of MM. The revealing of mutations in the BRAF/MEK/ERK pathway has led to the development of BRAF inhibitors such as vemurafenib and dabrafenib for the treatment of cutaneous MM. Though, progression of resistance to these agents has prompted attempts to target downstream proteins in this pathway. Trametinib, a MEK1/2 inhibitor, was approved in 2013 for the treatment of BRAF V600E/K mutation-positive unresectable or metastatic cutaneous melanoma patients. Areas covered: The aim of the current review is to present an update on the role of MEK in progressive melanomas and summarize latest results of clinical studies with innovative MEK inhibitors and/or combined approaches with other kinase inhibitors such as BRAF inhibitors in the treatment of MM. Expert opinion: Two combined treatments (i.e. trametinib plus dabrafenib and vemurafenib plus cobimetinib) target two different kinases in the BRAF/MEK/ERK pathway. The simultaneous prohibition of both MEK and BRAF is associated with more durable response rate than BRAF monotherapy and can overcome acquired resistance.

    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 melanoma features in Tunisia are closer to those of non-Caucasians, even though gender differences that are similar to those observed in Caucasians were uncovered. This study also emphasizes the aggressiveness of NM and its effect on melanoma patient deaths. Xeroderma pigmentosum stands as the major predisposing host factor. © 2016 The International Society of Dermatology.

    Immune checkpoint therapy has dramatically changed treatment options in patients with metastatic melanoma. However, a relevant part of patients still does not respond to treatment. Data regarding the prognostic or predictive significance of preexisting immune responses against tumour antigens are conflicting. Retrospective data suggested a higher clinical benefit of ipilimumab in melanoma patients with preexisting NY-ESO-1-specific immunity. Twenty-five patients with previously untreated or treated metastatic melanoma and preexisting humoural immune response against NY-ESO-1 received ipilimumab at a dose of 10 mg/kg in week 1, 4, 7, 10 followed by 3-month maintenance treatment for a maximum of 48 weeks. Primary endpoint was the disease control rate (irCR, irPR or irSD) according to immune-related response criteria (irRC). Secondary endpoints included the disease control rate according to RECIST criteria, progression-free survival and overall survival (OS). Humoural and cellular immune responses against NY-ESO-1 were analysed from blood samples. Disease control rate according to irRC was 52%, irPR was observed in 36% of patients. Progression-free survival according to irRC was 7.8 months, according to RECIST criteria it was 2.9 months. Median OS was 22.7 months; the corresponding 1-year survival rate was 66.8%. Treatment-related grade 3 AEs occurred in 36% with no grade 4-5 AEs. No clear association was found between the presence of NY-ESO-1-specific cellular or humoural immune responses and clinical activity. Ipilimumab demonstrated clinically relevant activity within this biomarker-defined population. NY-ESO-1 positivity, as a surrogate for a preexisting immune response against tumour antigens, might help identifying patients with a superior outcome from immune checkpoint blockade. NCT01216696.

    Full Text Available Isolated pleural metastasis with pleural effusion is a rare occurrence in malignant melanoma. We report an unusual case of a patient with chronic lymphocytic leukemia (CLL and recurrent pleural effusions. The pleural fluid cytology and immunohistochemistry profile were consistent with the diagnosis of CLL. However, chemotherapy with pentostatin, cyclophosphamide, and rituximab did not result in any meaningful clinical response. A video-assisted thoracoscopic surgery and biopsy of the affected nodular parietal layer of the pleura were consistent with malignant melanoma. Our case underlines the importance of having a suspicion for secondary causes of effusion in patients with CLL. We briefly discuss the mechanisms of an increased incidence of secondary cancers in CLL and the diagnosis of isolated pleural metastases in malignant melanoma.

    Purpose: The incidence of non-melanoma skin cancer (NMSC) has been increasing over the past 30 years. There are different treatment options and surgical excision is the most frequent treatment due to its low rates of recurrence. Radiotherapy is an effective alternative of surgery, and brachytherapy (BT) might be a better therapeutic option due to high radiation dose concentration to the tumor with rapid dose fall-off resulting in normal tissues sparing.

    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.

    Proton beam irradiation resulted in clinical and/or histopathological regression of large ciliary body and choroidal melanomas in three eyes. Enucleations were performed 6 1/2 weeks, five months, and 11 months after irradiation for angle-closure glaucoma from total retinal detachment, increase in retinal detachment, and neovascular glaucoma, respectively. A direct relationship was found between the length of the interval from irradiation to enucleation and the degree of histologic changes. Vascular changes in the tumors included endothelial cell swelling and decreased lumen size, basement membrane thickening, collapse of sinusoidal vessels, and thrombosis of vessels. Although apparently unaltered tumor cells remained, degenerative changes occurred in some melanoma cells, including lipid vacuoles in cytoplasm, pyknotic nuclei, and balloon cell formation. Patchy areas of necrosis and proteinaceous exudate were present. Pigment-laden macrophages were found near tumor vessels and all had a substantial chronic inflammatory infiltrate. The effect of proton beam irradiation on tumor vessels probably plays an important role in uveal melanoma regression

    Free radicals in A-2058 human melanoma cells were studied by the use of electron paramagnetic resonance (EPR) spectroscopy. The aim of this work was to determine the changes in relative free radical concentrations in tumor A-2058 cells after treatment by valproic acid (VPA) and 5,7-dimethoxycoumarin (DMC). The influences of VPA and DMC on free radicals in A-2058 cells were compared with those for human melanoma malignum A-375 and G-361 cells, which were tested by us earlier. Human malignant melanoma A-2058 cells were exposed to interactions with VPA, DMC, and both VPA and DMC. The tumor cells A-2058 were purchased from LGC Standards (Lomianki, Poland), and they were grown in the standard conditions: at 37°C and in an atmosphere containing 95% air and 5% CO2, in the Minimum Essential Medium Eagle (MEM, Sigma-Aldrich). The A-2058 cells were incubated with VPA (1 mM) and DMC (10 μM) for 4 days. The first-derivative EPR spectra of the control A-2058 cells, and the cells treated with VPA, DMC, and both VPA and DMC, were measured by the electron paramagnetic resonance spectrometer of Radiopan (Poznań, Poland) with microwaves from an X-band (9.3 GHz). The parameters of the EPR lines: amplitudes (A), integral intensities (I), line widths (ΔBpp), and g-factors, were analyzed. The changes of amplitudes and line widths with microwave power increasing from 2.2 to 70 mW were drawn evaluated, o-Semiquinone free radicals of melanin biopolymer are mainly responsible for the EPR lines of A-2058 melanoma malignum cells. The amounts of free radicals in A-2058 cells treated with VPA, and both VPA and DMC, were lower than in the untreated control cells. Application of the tested substances (VPA, and both VPA and DMC) as the antitumor compounds was discussed. DMC without VPA did not decrease free radicals concentration in A-2058 cells. The studies con-firmed that EPR spectroscopy may be used to examine interactions of free radicals with antitumor compounds.

    We explored in a phase I/II clinical trial the combination of valproic acid (VPA), a clinically available histone deacetylase inhibitor, with standard chemoimmunotherapy in patients with advanced melanoma, to evaluate its clinical activity, to correlate the clinical response with the biological activity of VPA and to assess toxicity. Patients were treated initially with VPA alone for 6 weeks. The inhibition of the target in non-tumour peripheral blood cells (taken as a potential surrogate marker) was measured periodically, and valproate dosing adjusted with the attempt to reach a measurable inhibition. After the treatment with valproate alone, dacarbazine plus interferon-α was started in combination with valproate. Twenty-nine eligible patients started taking valproate and 18 received chemoimmunotherapy and are assessable for response. We observed one complete response, two partial remissions and three disease stabilisations lasting longer than 24 weeks. With the higher valproate dosages needed to reach a measurable inhibition of the target, we observed an increase of side effects in those patients who received chemoimmunotherapy. The combination of VPA and chemoimmunotherapy did not produce results overtly superior to standard therapy in patients with advanced melanoma and toxicity was not negligible, casting some doubts on the clinical use of VPA in this setting (at least in the administration schedule adopted).

    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.

    Somatic sequencing of cancers has produced new insight into tumorigenesis, tumor heterogeneity, and disease progression, but the vast majority of genetic events identified are of indeterminate clinical significance. Here, we describe a NextGen sequencing approach to fully analyzing 248 genes, including all those of known clinical significance in melanoma. This strategy features solution capture of DNA followed by multiplexed, high-throughput sequencing and was evaluated in 31 melanoma cell lines and 18 tumor tissues from patients with metastatic melanoma. Mutations in melanoma cell lines correlated with their sensitivity to corresponding small molecule inhibitors, confirming, for example, lapatinib sensitivity in ERBB4 mutant lines and identifying a novel activating mutation of BRAF. The latter event would not have been identified by clinical sequencing and was associated with responsiveness to a BRAF kinase inhibitor. This approach identified focal copy number changes of PTEN not found by standard methods, such as comparative genomic hybridization (CGH). Actionable mutations were found in 89% of the tumor tissues analyzed, 56% of which would not be identified by standard-of-care approaches. This work shows that targeted sequencing is an attractive approach for clinical use in melanoma. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available BackgroundUveal melanoma is a rare and aggressive subtype of melanoma, with singular characteristics that separate it from the most famous cutaneous melanoma. This uncommon condition becomes even rarer if we look at young population. Common chemotherapy regimens does not work with this aggressive disease in its metastatic scenario, and the new armament like targeted and immunotherapies are still looking for more robust evidence.Case presentationWe report a rare case of uveal melanoma in a patient younger than 20 years, with abdominal pain as his initial complaint. He did not present the typical visual symptoms of the primary site because of an auto accident suffered 4 months before the presentation, letting him blind of the eye affected by the tumor development.ConclusionThere is always a possibility of the diagnosis of uveal melanoma in cases with associated isolated hepatic metastases, even in a young population, where this hypothesis is often rejected by the epidemiological frequency of other tumors. This rare case is a useful example.

    The development of targeted inhibitors, like vemurafenib, has greatly improved the clinical outcome of BRAF(V600E) metastatic melanoma. However, resistance to such compounds represents a formidable problem. Using whole-exome sequencing and functional analyses, we have investigated the nature and pleiotropy of vemurafenib resistance in a melanoma patient carrying multiple drug-resistant metastases. Resistance was caused by a plethora of mechanisms, all of which reactivated the MAPK pathway. In addition to three independent amplifications and an aberrant form of BRAF(V600E), we identified a new activating insertion in MEK1. This MEK1(T55delins) (RT) mutation could be traced back to a fraction of the pre-treatment lesion and not only provided protection against vemurafenib but also promoted local invasion of transplanted melanomas. Analysis of patient-derived xenografts (PDX) from therapy-refractory metastases revealed that multiple resistance mechanisms were present within one metastasis. This heterogeneity, both inter- and intra-tumorally, caused an incomplete capture in the PDX of the resistance mechanisms observed in the patient. In conclusion, vemurafenib resistance in a single patient can be established through distinct events, which may be preexisting. Furthermore, our results indicate that PDX may not harbor the full genetic heterogeneity seen in the patient's melanoma. © 2015 The Authors. Published under the terms of the CC BY 4.0 license.

    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.

    Systemic therapy for metastatic melanoma has evolved rapidly during the last decade, and patient treatment has become more complex. To evaluate the survival benefit achieved through surgical resection of melanoma metastatic to the abdominal viscera in patients treated in the modern treatment environment. This retrospective review of the institutional melanoma database from the John Wayne Cancer Institute at Providence St Johns Health Center, a tertiary-level melanoma referral center, included 1623 patients with melanoma diagnosed as having potentially resectable abdominal metastases before (1969-2003) and after (2004-2014) advances in systemic therapy. Overall survival (OS). Of the 1623 patients identified in the database with abdominal melanoma metastases, 1097 were men (67.6%), and the mean (SD) age was 54.6 (14.6) years. Of the patients with metastatic melanoma, 1623 (320 [19.7%] in the 2004-2014 period) had abdominal metastases, including 336 (20.7%) with metastases in the gastrointestinal tract, 697 (42.9%) in the liver, 138 (8.5%) in the adrenal glands, 38 (2.3%) in the pancreas, 109 (6.7%) in the spleen, and 305 (18.8%) with multiple sites. Median OS was superior in surgical (n = 392; 18.0 months) vs nonsurgical (n = 1231; 7.0 months) patients (P treatment with metastasectomy (HR, 0.59; 95% CI, 0.46-0.74; P treatment era did not significantly affect outcomes (HR, 0.82; 95% CI, 0.67-1.02; P = .15). Overall, patients with gastrointestinal tract metastases undergoing complete, curative resection derived the greatest benefit, with a median OS of 64 months. To our knowledge, this series is the largest single-institution experience with abdominal melanoma metastases, demonstrating that surgical resection remains an important treatment consideration even in the systemic treatment era.

    Regression has been proposed as a potential marker of dissemination in thin melanomas. Previous studies have shown conflicting results. To determine if regression in melanoma is associated with an increased risk of sentinel lymph node (SLN) metastasis. A cohort analysis was conducted. Data on all patients were collected on a standardized case report form during 10 years. A total of 397 consecutive patients with melanoma who underwent a SLN biopsy were analysed. All cases of melanoma and SLN biopsies were examined by the same two pathologists. Differences between melanomas with and without SLN metastasis were compared using Fisher's exact test or the two-sample t-test and the chi(2) test. Multivariable logistic regression was used to adjust for possible confounding factors. We analysed 397 patients (411 melanomas) who underwent a SLN biopsy. The median Breslow index was 1.8 mm (interquartile range 1.1-3). Regression was observed in 23% (n = 94). SLN metastases were observed in 26% (n = 106). The frequency of SLN metastasis was 16% in melanomas with regression and 29% without regression (P = 0.012). The adjusted odds ratio (OR) for regressive melanoma was 0.9 [95% confidence interval (CI) 0.4-1.9; P = 0.777]. The risk of SLN metastasis was increased in melanoma cases with a Breslow index from 1.5 to or= 2.0 mm (adjusted OR 3.5; 95% CI 1.7-7.4; P = 0.001) and ulceration of the melanoma (adjusted OR 1.8; 95% CI 1.1-3.2; P = 0.03). Regression is not an independent predictor of the risk of SLN metastasis in melanoma.

    Previous interventions (excisional biopsy, incomplete dissection) in the regional basin that drain a melanoma site prior to definitive surgical procedures significantly increase the risk of melanoma recurrence in the surgical field. Retrospective analysis. Tertiary care referral center. One hundred forty-one consecutive patients who underwent radical lymph node dissection (RLND) either in the groin or the axilla owing to malignant melanoma were followed up for a median period of 41 months. All of the 141 patients received either elective or therapeutic RLND. Their medical records were analyzed for demographic data, disease history, previous treatments, recurrence patterns, and survival. Patterns of first recurrence after RLND and survival. Radical lymph node dissection was performed on 148 lymph node basins (141 patients; 86 axillae and 62 groins). Nineteen patients (13%) received previous open interventions in the lymph node basin (tampering) other than radical dissection. Radical lymph node dissection was performed prophylactically in 38 basins (26%), for palpable disease in 75 (51%), and for a positive sentinel node in 35 (24%). There were 74 failures (52%) of RLND: 51 patients (70%) with systemic disease, 12 (16%) with recurrence in the surgical field, 9 (11%) with in-transit metastases, and 2 (3%) with local recurrence. On multivariate analysis, the only significant predictors of recurrence after RLND were Breslow thickness of greater than 4 mm (P = .02), tampering (P = .01), and lymph node capsular invasion (P = .001). Tampering was the only independent prognosticator of failure in the surgical field, as tampering was noted in 10 (83%) of 12 patients with failure in the surgical field as compared with 6 (10%) of 62 patients with other types of first failures (Pbasin that drain a melanoma site prior to definitive surgical procedures significantly increase the risk of melanoma recurrence in the surgical field, and they should be avoided.

    Genetic susceptibility to cutaneous melanoma has been investigated in Italian high-risk melanoma patients from different geographical regions. CDKN2A, CDK4, and MC1R genes have been screened in most studies, MITF and POT1 were screened in only one study, and none analyzed the TERT promoter. We carried out a mutational analysis of CDKN2A, CDK4 exon 2, POT1 p.S270N, MITF exon 10, MC1R, and the TERT promoter in 106 high-risk patients with familial melanoma (FM) and sporadic multiple primary melanoma (spMPM) from Central Italy and evaluated mutations according to the clinicopathological characteristics of patients and lesions. In FM, CDKN2A mutations were detected in 8.3% of the families, including one undescribed exon 1β mutation (p.T31M), and their prevalence increased with the number of affected relatives within the family. MC1R variants were identified in 65% of the patients and the TERT rs2853669 promoter polymorphism was identified in 58% of the patients. A novel synonymous mutation detected in MITF exon 10 (c.861A>G, p.E287E), although predicted as a splice site mutation by computational tools, could not functionally be confirmed to alter splicing. For spMPM, 3% carried CDKN2A mutations, 79% carried MC1R variants, and 47% carried the TERT rs2853669 promoter polymorphism. MC1R variants were associated with fair skin type and light hair color both in FM and in spMPM, and with a reduction of age at diagnosis in FM patients. Mutations in CDK4 exon 2 and the POT1 p.S270N mutation were not detected. A low frequency of CDKN2A mutations and a high prevalence of MC1R variants characterize high-risk melanoma patients from Central Italy.

    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

    Skin cancer follow-up is a substantial burden to outpatient clinics. Few studies have investigated patients' views on skin cancer follow-up and cutaneous melanoma. The objective was to investigate patients' perceived benefits and the impact of follow-up. This study included an open sample of patients attending routine follow-up at the outpatient Departments of Plastic Surgery and Dermatology, Roskilde Hospital. A total of 218 follow-up patients diagnosed with cutaneous malignant melanoma (MM), non-melanoma skin cancer (NMSC) or actinic keratosis (AK) completed a structured interview. A total of 97% patients found follow-up useful. Continuity and consistency were important. One third of patients felt some degree of pre follow-up anxiety. The number of anxious MM patients was significantly greater than that of NMSC patients. No significant difference was found between the number of anxious MM and AK patients. Female gender, cohabitation and age younger than 50 years were associated with increased levels of anxiety. No relation was found between the number of anxious patients or the level of anxiety and the duration of the follow-up period. The majority of patients who attended found that the follow-up had been useful. Certain demographic characteristics were associated with higher levels of anxiety and may be addressed by supportive efforts targeting these groups.

    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. This is a pilot trial (ClinicalTrials.gov identifier: NCT00937625) including patients with metastatic melanoma, PS ≤1, age involvement of the central nervous system. Six patients were treated with lymphodepleting chemotherapy, TIL infusion, and 14 days of subcutaneous low-dose IL-2 injections, 2 MIU/day. 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. 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.

    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

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

    The role of SLNB for in-transit (IT) melanoma is controversial. The objective of this study was to determine the rate and prognostic significance of occult nodal disease in patients undergoing surgical nodal staging for IT disease. We conducted a retrospective review of patients with IT melanoma from May 2005 through September 2014. Analysis was limited to patients with a first-time IT event who underwent surgical excision. Associations between clinicopathologic characteristics, patterns of recurrence, and survival were analyzed. A total of 261 patients treated at our center were identified and 157 met inclusion criteria, of which 135 (86%) presented with no evidence of nodal disease. At the time of surgical excision of the IT lesion, 80 (58%) clinically node-negative patients underwent observation of the nodal basin and 55 (41%) surgical nodal staging. Twenty (36%) clinically node-negative but surgically staged patients were found to have nodal disease. Distant metastasis-free survival was 70.8 months for surgically staged node-negative patients, 19.2 months for surgically staged node-positive patients, 22.8 months for those staged node-negative by clinical examination only and 4.8 months for those with clinical nodal disease (p = 0.01). The regional nodal basin was the first site of failure in 14 of 66 (21%) clinically staged patients, 5 of 50 (10%) for those surgically staged, and 6 of 16 (38%) for those with clinical nodal disease. Patients with IT disease are at high risk for occult nodal metastasis. Because clinical staging is unreliable, SLNB should be considered. For patients with IT recurrence, the status of the regional basin is strongly prognostic and stratifies patients into low-, intermediate-, and high-risk groups.

    A germline polymorphism of the microphthalmia transcription factor (MITF) gene encoding a SUMOylation-deficient E318K-mutated protein has recently been described as a medium-penetrance melanoma gene. In a clinical assessment of nevi from 301 volunteers taken from Queensland, we identified six individuals as MITF E318K mutation carriers. The phenotype for 5 of these individuals showed a commonality of fair skin, body freckling that varied over a wide range, and total nevus count between 46 and 430; in addition, all were multiple primary melanoma patients. The predominant dermoscopic signature pattern of nevi was reticular, and the frequency of globular nevi in carriers varied, which does not suggest that the MITF E318K mutation acts to force the continuous growth of nevi. Excised melanocytic lesions were available for four MITF E318K carrier patients and were compared with a matched range of wild-type (WT) melanocytic lesions. The MITF staining pattern showed a predominant nuclear signal in all sections, with no significant difference in the nuclear/cytoplasmic ratio between mutation-positive or -negative samples. A high incidence of amelanotic melanomas was found within the group, with three of the five melanomas from one patient suggesting a genetic interaction between the MITF E318K allele and an MC1R homozygous red hair color (RHC) variant genotype.

    Melanomas are highly heterogeneous tumors and there is no treatment effective at achieving long-term remission for metastatic melanoma patients. Thus, an appropriate model system for studying melanoma biology and response to drugs is necessary. It has been shown that composition of the medium is a critical factor in preserving the complexity of the tumor in in vitro settings, and melanospheres maintained in stem cell medium are a good model in this respect. In the present study, we observed that not all nodular melanoma patient-derived cell populations grown in stem cell medium were capable of forming melanospheres, and cell aggregates and anchorage-independent single-cell cultures emerged instead. Self-renewing capacity and unlimited growth potential indicated the presence of cells with stem-like properties in all patient-derived populations but immunophenotype and MITF expression exhibited variability. Enhanced MITF expression and activity was observed in melanospheres in comparison with cell aggregates and single-cell culture, and hypoxic-like conditions that increased the ability of single-cell population to form melanospheres enhanced MITF expression and cell pigmentation as well. Thus, MITF seems to be a critical transcription factor for formation of both patient-derived and hypoxia-induced melanospheres. After 2 years of continuous culturing, melanospheres progressively underwent transition into cell aggregates that was accompanied by changes in expression of several MITF-dependent genes associated with melanogenesis and survival and alterations in the composition of subpopulations but not in the frequency of ABCB5-positive cells. Several biological properties of parent tumor are well preserved in patient-derived melanospheres, but during prolonged culturing the heterogeneity is substantially lost when the melanospheres are substituted by cell aggregates. This should be considered when cell aggregates instead of melanospheres are used in the study of

    Recent advances in melanoma therapy have influenced the management of metastatic patients. Inhibitors of the BRAF/MEK/ERK signaling cascade have been proven highly effective in the metastatic disease although displaying different side effects. Here, we report a patient with BRAF V600E-mutated stage IV melanoma who developed a severe leukopenia upon targeted therapy with the BRAF inhibitor vemurafenib. Interestingly, the immediate therapeutic switch to a different BRAF inhibitor 'dabrafenib? had no negative influence on the leukocyte count. This case supports recent studies, which showed a differential influence of different BRAF inhibitors on patients' leukocytes despite similar clinical efficacy in melanoma.

    In the postoperative management of patients with malignant melanoma, CT and MRI are both used for screening of recurrent disease more frequently in Japan than in other countries. We evaluated the usefulness of various imaging methods during the postoperative period by retrospective analysis of 142 patients with Stage I-III malignant melanoma. Metastases were found in 44 of 142 patients (31%) during the follow-up period. In 28 cases, the metastases were detected by a routine physical examination, but by imaging tests including CT, MRI, Ga/Tc scintigraphy and positron emission tomography (PET) in 16 cases. Elevated serum markers including 5-S-cysteinyldopa (5-SCD), melanoma inhibitory activity (MIA) and lactate dehydrogenase (LDH) were observed in 24%, 72%, and 12% of patients who developed metastases, respectively. There was no significant difference in overall survival rate between in patients with metastasis detected by a routine physical examination and in patients with metastasis detected by imaging methods (p=0.27). In contrast, there was a significantly longer overall survival rate in patients with operable metastasis compared with those with inoperable metastasis (p=0.001). Patients with operable stage IV disease showed a longer overall survival rate than did patients with inoperable disease (p=0.07). The results suggest that early detection of melanoma metastases may improve the survival rate of patients. However, frequent systemic evaluation by imaging methods is strongly discouraged due to costs and effects. An adequate follow-up schedule should be justified according to the risk of each patient.

    We report here on a patient with metastatic melanoma who had extensive brain metastases. After being treated with the sequential combination of whole brain radiation therapy followed by the PD-1-inhibitory antibody, pembrolizumab, the patient had a durable complete response. Retrospective laboratory studies of T cells revealed that, after treatment with anti-PD-1 commenced, effector CD8 + T cells in the blood expanded and the ratio of CD8 + :Treg T cells increased. A CD8 + T-cell clone present in the initial brain metastases was expanded in the blood after anti-PD-1 treatment, which suggested an antitumor role for this clone. Immunohistochemical analysis confirmed the presence of CD8 + T cells and low PD-L1 expression in the brain metastases before immunotherapy initiation. This sequence of therapy may provide an option for melanoma patients with unresponsive brain metastases. Cancer Immunol Res; 5(2); 100-5. ©2017 AACR. ©2017 American Association for Cancer Research.

    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...... was substantially stalled and both patients were alive for more than 15 months after initiation of therapy. Specific CTL reactivity against several tumor antigens was detectable in peripheral blood, which declined just before reactivation of disease progression. Furthermore, CD3 zeta -chain expression detected...... 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...

    PURPOSE: To evaluate the prognostic effect of a combination of American Joint Committee on Cancer (AJCC) staging (7th edition) and genetic status in patients with posterior uveal melanoma. METHODS: A consecutive cohort of 153 patients with posterior uveal melanoma treated at Copenhagen University...... prognostic effects of AJCC staging and cytogenetic changes were evaluated by cumulative incidence curves and Cox proportional hazard models. RESULTS: An overall 5-year survival rate of 62% (95% confidence interval [CI]: 0.50-0.73) was observed. A normal genetic status of chromosomes 3 and 8, as found in 42...... patients (30%), minimized the additional prognostic effect of AJCC staging. The frequency of tumors with normal genetic status decreased with increasing AJCC stage. Both AJCC stage III (hazard ratio [HR]: 11.0, 95% CI: 1.4-85.6) and abnormal copy number of chromosomes 3 (HR: 6.3, 95% CI: 1.4-28.3) and 8...

    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.

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

    We explored the potential association of depression history and personality, evaluated through a robust questionnaire tool, namely the Eysenck Personality Scale, with disease risk and progression among Greek patients. A total of 106 melanoma patients and their 1 : 1 sex-matched controls were interviewed on the basis of a questionnaire comprising phenotypic, sociodemographic, lifestyle and medical history variables, as well as information on history of lifetime major depression. The Eysenck Personality Questionnaire, measuring the four personality dimensions (extraversion, neuroticism, psychoticism, lie), was thereafter completed. Adjusted odds ratios (ORs) for melanoma risk were derived through multiple logistic regression analyses, whereas potential predictors of survival were explored using Cox proportional hazards models. Sun sensitivity score [OR: 1.55, 95% confidence interval (CI): 1.16-2.06] and major depression history (OR: 5.72, 95% CI: 1.38-23.73) were significantly associated with melanoma, whereas inverse associations of extraversion (OR: 0.90, 95% CI: 0.83-0.97) and psychoticism score (OR: 0.88, 95% CI: 0.78-1.00) were noted. These associations were more pronounced and remained solely among female patients; notably, decreased extraversion (OR: 0.86, 95% CI: 0.76-0.98) and psychoticism score (OR: 0.63, 95% CI: 0.43-0.91), as well as increased depression history (OR: 10.69, 95% CI: 1.43-80.03) were evident. Cox-derived hazard ratios showed nonsignificant associations of depression history and personality with disease outcome. Our data support the hypotheses that depression history and personality are associated with melanoma risk. No effect on survival after cancer diagnosis was observed. If confirmed in future studies, these associations may contribute toward better understanding the etiology of melanoma, enhancing health-related quality of life.

    Melanoma in the Western world has an increasing incidence. One of the most important factor for the increase in incidence is sporadic, uncontrolled exposure to the sun. The basis for the treatment of primary melanoma is surgical treatment. Treatment of metastatic disease of melanoma in recent years experienced significant changes. BRAF and MEK inhibitors, immunotherapy with programmed cell-death immune checkpoint inhibitors (anti-PD-1-antibodies) are new options for the treatment of metastatic disease. A mulitidisiplinary team of Croatian Society for Medical Oncology provides recommendations for diagnosis, treatment and follow-up of melanoma primarily driven to the discovery of new drugs and therapeutic options, that change the prognosis of patients with metastatic melanoma.

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

    Factors associated with the detection of cutaneous melanomas and reasons for delay in diagnosis were investigated in 429 patients with histologically proven melanoma operated on between January 1993 and June 1996. Patients were interviewed using a standardized questionnaire. In 25% of patients, treatment was delayed for more than 1 year from the time they first noticed a suspicious pigmented lesion. Melanoma was detected by the patients themselves in 67% of women and 45% of men. The three predominant clinical symptoms of melanoma were change in colour (darker), increase in size and increase in elevation of a pigmented lesion. The role of sun exposure and of naevi as risk factors for melanoma, as well as the potential benefit of early treatment, were known by 87%, 66% and 82% of the patients, respectively. However, melanoma awareness had no impact on the time period between first observation of skin changes and treatment. Among the factors associated with delay in melanoma diagnosis, an initial incorrect diagnosis as a benign lesion by the physician first visited (in 18% of all cases) had the highest significance. Patients detecting their lesions themselves were treated significantly later than patients in whom others had remarked on changes in a naevus. Furthermore, melanomas of the head and neck were treated later than melanomas at other body sites. Further efforts to educate both the public and the medical profession are essential to ensure earlier treatment for cutaneous melanomas.

    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

    A study of the {sup 10}B-enriched p-boronophenylalanine-fructose complex ({sup 10}BPA-F) infusion procedure in potential BNCT patients, including four melanoma of extremities and two high-grade gliomas (glioblastoma and ganglioglioma) was performed. T/B and S/B ratios for {sup 10}B concentrations in tumor (T), blood (B) and skin (S) were determined. The T/B ratio for the glioblastoma was in the 1.8-3.4 range. The ganglioglioma did not show any significant boron uptake. For the nodular metastasic melanoma T/B values were between 1.5 and 2.6 (average 2.1{+-}0.4), corresponding to the lower limit of the mean values reported for different melanoma categories. This result might suggest a lower boron uptake for nodular metastasic melanomas. S/B was 1.5{+-}0.4. An open two-compartment pharmacokinetic model was applied to predict the boron concentration during the course and at the end of a BNCT irradiation.

    The prognosis of sentinel node (SN)-positive melanoma patients is predicted by a number of characteristics such as size and site of the metastases in the SN. The pathway and prognosis of strong pigmentation of melanoma metastases in the SN is unclear. The aim of this study is to evaluate the role of pigmentation and growth pattern of metastases in the SN with respect to survival. A total of 389 patients underwent an SN procedure (1997-2011). Ninety-five patients had a positive SN and material from 75 patients was available for review. The median follow-up time was 75 months (range 6-164). Pigmentation was scored from 0 to 2 using the following scale: 0=absent, 1=slight, and 2=strong. Growth pattern was scored as either eccentric (1) or infiltrative (2). SN tumor burden was measured according to the Rotterdam criteria. The primary melanoma had a median Breslow thickness of 2.90 mm (0.8-12.00 mm). Ulceration was present in 34 patients (45.3%). There was a median SN tumor burden of 0.5 mm (0.05-7.00 mm). In a total of 75 patients, 59 patients (79%) had no pigmentation, 13 patients (17%) had slight pigmentation, and three patients (4%) had strong pigmentation in the SN. Because of the small numbers, the classification was modified to either absent 59 (79%) or present 16 (21%) pigmentation, respectively. The SN tumor burden was significantly higher (P=0.031) for patients with pigmentation. Patients with pigmentation had a 5-year melanoma-specific survival (MSS) of 47% and a 10-year MSS of 33%. Patients without pigmentation had a 5-year MSS of 70% and a 10-year MSS of 59% (P=0.06). There was no difference in MSS for patients with an eccentric or an infiltrative growth pattern, nor did it correlate with other prognostic factors. Multivariate analysis for MSS showed five significant factors associated with worse prognosis: male sex (P=0.036), nodular melanoma (P=0.001), truncal site (P=0.0001), SN tumor burden more than 1.0 mm (P=0.022), and positive completion lymph node

    BRAF gene mutations have been observed in 30-50 % of malignant melanoma patients. Recent development of therapeutic intervention using BRAF inhibitors requires an accurate and rapid detection system for BRAF mutations. In addition, the clinical characteristics of the melanoma associated with BRAF mutations in Japanese patients have not been investigated on a large scale evaluation. We recently established quenching probe system (QP) for detection of an activating BRAF mutation, V600E and evaluated 113 melanoma samples diagnosed in Saga University Hospital from 1982 to 2011. The QP system includes fully automated genotyping, based on analysis of the probe DNA melting curve, which binds the target mutated site using a fluorescent guanine quenched probe. BRAF mutations were detected in 54 of 115 (47 %) including 51 of V600E and 3 of V600 K in Japanese melanoma cases. Among clinical subtypes of melanoma, nodular melanoma showed high frequency (12 of 15; 80 %) of mutation followed by superficial spreading melanoma (13 of 26; 50 %). The QP system is a simple and sensitive method to determine BRAF V600E mutation, and will be useful tool for patient-oriented therapy with BRAF inhibitors.

    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.

    Langerhans cells (LCs) from melanoma patients sentinel lymph nodes (SLN) are poor T cell activators mostly due to an immature immunophenotype. However Antigen Presenting Machinery (APM) role is unknown. We investigated HLA-class I APM components (Delta, LMP-7/10, TAP-1, Calnexin, Tapasin, β2-microglobulin and HLA-A,B,C) in LCs from healthy donors skin and melanoma patients SLN. APM component levels were low in immature epidermal LCs and significantly increased after maturation (pmelanoma Breslow's thickness and SLN metastases: HLA-A,B,C level was significantly lower in SLN LCs from thick lesions patients compared with those from thin/intermediate lesions (pmelanoma, contributing to design new LCs-based therapeutic approaches.

    Non-healing chronic trophic ulceration is very common in leprosy patients. Marjolin's ulcer consists of the malignant transformation of a chronic ulcerative lesion. Nodular melanoma developing from Marjolin's ulcer, caused by a trophic ulceration of a leprosy patient, is very rare with only a few cases reported in the literature. Due to the disguised presentation of these malignancies within trophic ulceration lesions in leprosy, neoplastic transformation is frequently overlooked, leading to misdiagnosed and delayed treatment. This paper reports a case of an 83-year-old man with lepromatous leprosy and chronic ulceration on the foot for 22 years. Over a period of 2 months, the ulcer enlarged, turned black, and became more painful. The patient underwent regional excision and immunotherapy after the diagnosis of malignant nodular melanoma. After 9 months follow-up, no metastasis was found. There were no external sources of funding for this study. The authors have no conflicts of interest to declare.

    Full Text Available Melanomas are a major cause of premature death from cancer. The gradual decrease in rates of morbidity and mortality has occurred as a result of public health campaigns and improved rates of early diagnosis. Survival of melanoma has increased to over 90%. Management of melanoma involves a number of components: excision, tumor staging, re-excision with negative margins, adjuvant therapies (chemo, radiation or surgery, treatment of stage IV disease, follow-up examination for metastasis, lifestyle modification and counseling. Sentinel lymph node status is an important prognostic factor for survival in patients with a melanoma >1 mm. However, sentinel lymph node biopsies have received partial support due to the limited data regarding the survival advantage of complete lymph node dissection when a micrometastasis is detected in the lymph nodes. Functional mutations in the mitogen-activated pathways are commonly detected in melanomas and these influence the growth control. Therapies that target these pathways are rapidly emerging, and are being shown to increase survival rates in patients. Access to these newer agents can be gained by participation in clinical trials after referral to a multidisciplinary team for staging and re-excision of the scar.

    The detection of melanoma cells in peripheral blood has been proposed to select patients with a high risk of relapse. In this study, tyrosinase and melanoma antigen recognized by T cells 1 (MART-1) mRNA expression was evaluated in serial samples obtained before definitive surgery and during follow...... level, and histological subtype were analyzed together with tyrosinase and MART-1 mRNA treated as updated covariates in a Cox proportional-hazard model. After a median follow-up time of 66 months, 42 out of 236 patients (18%) had relapsed. The following variables were significantly associated...... with relapse-free survival in the univariate analyses: tyrosinase, MART-1, gender, ulceration, thickness, Clark level, and histological subtype. Entering these covariates into a multivariate Cox analysis resulted in thickness as the single independent prognostic factor (P

    Full Text Available Anorectal melanomas represent a group of mucosal melanomas with unknown etiology and poor prognosis. The lesions can be misdiagnosed as hemorrhoids during clinical examination. We reviewed the morphological and clinical features of 14 anorectal melanomas, and discuss the treatment modalities of this entity. Fourteen patients who were diagnosed with anorectal malignant melanoma between 1997 and 2004 were evaluated with regard to age, sex, size, morphology, lymph node or distant metastasis, treatment modality and survival. Eight patients were female and six were male, and their mean age was 58 years. The size of melanoma ranged from 3 cm to 8 cm. Pathological evaluation revealed epithelioid and spindle cell type tumor in seven and two patients, respectively, whereas, in the remaining seven patients, the tumor was composed of both types. Pigmentation was apparent in all tumors. There was lymph node metastasis in 11 patients and distant metastasis in all patients. Eleven patients underwent abdominoperineal resection and three were treated by local excision. Mean survival was 8.7 months. Prognosis of anorectal melanoma remains poor. Awareness of the diverse clinicopathological features of these lesions, both on the part of the clinicians and pathologists, is crucial for their early detection and proper treatment.

    A limited number of studies have been performed so far on the polymorphism in the transmembrane region (exon 5) of the major histocompatibility complex class I chain-related gene A (MICA) in patients with melanoma. However, the influence of MICA polymorphism in extracellular domains (exons 2, 3, and 4) has not been investigated on melanoma disease. This study aims to characterize the influence of extracellular MICA polymorphism, and its previously described linkage disequilibrium with HLA-B locus, on patients with cutaneous melanoma from southeastern Spain. For this purpose, MICA and HLA-B genotyping was performed in 233 patients and 200 ethnically matched controls by luminex technology. Patients were classified according to the presence of methionine or valine at codon 129 of MICA gene. We found a high frequency of MICA*009 in melanoma patients compared with controls (P = 0.002, Pc = 0.03). Our results also showed an association between MICA*009 and HLA-B*51 alleles in both patients and controls. This association was stronger in patients than controls (P = 0.015). However, a multivariate logistic regression model showed that neither MICA*009 nor the combination MICA*009/HLA-B*51 was associated with melanoma susceptibility. No relationship was observed between MICA-129 dimorphism and melanoma nor when MICA polymorphism was evaluated according to clinical findings at diagnosis. PMID:25838620

    The goal of this study was to assess the relationship between the severity of obstructive sleep apnoea (OSA) and the levels of carcinogenesis- and tumour growth-related biomarkers in patients with cutaneous melanoma.This multicentre observational study included patients who were newly diagnosed with melanoma. The patients were classified as non-OSA (apnoea-hypopnoea index (AHI) 0-5 events·h -1 ), mild OSA (AHI 5-15 events·h -1 ) and moderate-severe OSA (AHI >15 events·h -1 ). ELISAs were performed to analyse the serum levels of hypoxia- and tumour adhesion-related biomarkers (vascular endothelial growth factor (VEGF), interleukin (IL)-8, intracellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM)-1) and markers of tumour aggressiveness (S100 calcium-binding protein B (S100B) and melanoma inhibitory activity (MIA)). A logistic model adjusted for age, sex and body mass index was fitted to each biomarker, and the AHI served as the dependent variable.360 patients were included (52.2% male, median (interquartile range) age 55.5 (43.8-68.0) years and AHI 8.55 (2.8-19.5) events·h -1 ). The levels of VEGF, IL-8, ICAM-1, S100B and MIA were not related to the severity of OSA. The levels of VCAM-1 were higher in patients with OSA than those without OSA (mild OSA: odds ratio (OR) 2.07, p=0.021; moderate-severe OSA: OR 2.35, p=0.013).In patients with cutaneous melanoma, OSA was associated with elevated circulating levels of VCAM-1 that could indicate the contribution of OSA in tumorigenesis via integrin-based adhesion.

    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.

    Atypical Mole Syndrome is the most important phenotypic risk factor for cutaneous melanoma, a malignancy that accounts for about 80% of deaths from skin cancer. Since early diagnosis of melanoma is of great prognostic relevance, the identification of Atypical Mole Syndrome carriers (sporadic and familial) is essential, as well as the recommendation of preventative measures that must be undertaken by these patients.We report two rare cases concerning patients with multiple primary skin melanomas in the setting of a familial and a sporadic syndrome of dysplastic nevi: the first patient is a 67-year-old patient with a history of multiple superficial spreading melanomas localized on his back. The second patient presented with multiple primary melanomas in advanced stage in the context of the so-called sporadic form of the syndrome of dysplastic nevi-AMS (atypical mole syndrome). In the first case, excision of the melanomas was carried out with an uneventful post-operative period. In the second case, disseminated metastases were detected, involving the right fibula, the abdominal cavity as well as multiple lesions in the brain. The patient declined BRAF mutation tests as well as chemotherapy or targeted therapies, and suffered a rapid deterioration in his general condition leading to death. We classified the second case as a sporadic form of the atypical mole syndrome, associated with one nodular and two superficial spreading melanomas.There are no data in the literature to allow us to understand if, in patients with multiple primary melanomas, there is any difference in terms of prognosis between those with and without a family history of a similar phenotype. To answer this and other questions related to these rare cases, further studies with a significant number of patients should be carried out.

    Genital melanoma is a rare pathology. We present the experience of two comprehensive cancer centers in Lyon (France) in the management of genital melanoma in order to identify prognostic factors and optimal treatments. Between April 1992 and Mars 2014, 16 patients with a primary genital melanoma were referred to our department. Nine patients presented a vaginal melanoma, six vulvar melanomas and only one cervical melanoma. The median dimension of the lesion was 33.7 mm (5-100 mm). The AJCC stage ranged from IB to IIIC. 12 cases were the classic dark-blue flat melanoma and the other 4 cases were an atypical amelanotic tumor. Wide local surgery was performed in nine patients. A radical surgery was performed in six patients. In the large cervical melanoma, radiotherapy was performed as first-line treatment. In all the patients regional lymph node staging was performed. Adjuvant treatment was realized in nine patients. Two patients are alive without recurrence. Only one patient was lost to the first follow-up. The other 13 patients experienced a rapid recurrence. The median disease-free survival and the median overall survival were 11.8 months (2-49 m) and of 30.4 m (11-144 m), respectively. The disease-free survival and overall survival could be linked to a clinical presentation (Breslow thickness and morphology of lesion) associated to the early diagnosis. In our small series, the most important prognosis factor remains the tumor thickness. These rare lesions should be treated in experienced centers in order to improve their prognostic.

    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.

    Full Text Available BackgroundPeriocular melanoma is a rare but often deadly malignancy that arises in the uvea (commonest origin, conjunctiva or orbit (rarest primary site. Melanoma accounts for 5–10% of metastatic/secondary orbital malignancies, but only a tiny proportion of primary orbital neoplasia. Primary orbital melanoma (POM is exceedingly rare, with approximately 50 cases reported to date.MethodsAll patients seen in the orbital unit at a tertiary referral hospital (1991–2016 with a biopsy-proven diagnosis of POM were identified from a diagnostic database and were studied. The case notes, imaging, surgical approach, and histology were reviewed.ResultsThirteen patients (five male; 38% presented with isolated malignant melanoma of the orbit, for which no other primary site was identified at presentation or during an average follow-up of 44 months (median 22; range 0–13 years. The patients presented between the ages of 40 and 84 years (mean 55.5; median 48 years and typically gave a short history of rapidly increasing proptosis and eyelid swelling. On the basis of history, a malignant lesion was suspected in most patients and all underwent incisional biopsy, with debulking of the mass in 10 (77% patients, and skin-sparing exenteration in 3/13 (23%. Ten patients underwent orbital radiotherapy and the survival to date ranged from 9 months to 14 years (mean 55 months; median 23 months; two patients received solely palliative care for widespread disease and one patient refused orbital radiotherapy. Five of the 13 (38% patients died from the disease.DiscussionPOM is a very rare malignancy, but clinical analysis of this cohort gives insight into disease presentation and prognosis. The tumor typically presents with a rapidly progressive, well-defined mass that is, in some cases, amenable to macroscopically intact excision. Unusual for malignant melanoma, some of these patients can show an unusually long period of quiescent disease after surgical

    The aim of this study was to investigate the feasibility of using layer-by-layer polymer coated gold nanoparticles (AuNP) as a carrier for topical iontophoretic delivery of imatinib mesylate (IM). AuNP were prepared by the Turkevich method and were stabilized and functionalized using polyvinylpyrrolidone and polyethylene imine. The functionalized AuNP were then sequentially coated with anionic poly(styrenesulfonate) and cationic polyethylene imine and loaded with IM. The layer-by-layer polymer coated AuNP (LbL-AuNP) showed average particle size and zeta-potential of 98.5 ± 4.3 nm and 32.3 ± 1.3 mV respectively. After LbL coating of AuNP, the surface plasmon resonance wavelength shifted from 518 to 530 nm. The loading efficiency of IM in LbL-AuNP was found to be 28.3 ± 2.3%, which was greatest for any small molecule loaded in AuNP. In vitro skin penetration studies in excised porcine ear skin showed that iontophoresis (0.47 mA/cm(2)) application enhanced the skin penetration of IM loaded AuNP by 6.2-fold compared to passive application. Tape stripping studies showed that iontophoresis of IM loaded LbL-AuNP retained 7.8- and 4.9-fold greater IM in stratum corneum and viable skin respectively compared with iontophoresis of free IM. LbL-AuNP were taken up rapidly (15 min) by B16F10 murine melanoma cells. Furthermore, IM loaded LbL-AuNP significantly (p < 0.001) decreased B16F10 cell viability compared to free IM. We have shown for the first time that IM can be delivered by topical application using LbL coated gold nanoparticles to treat 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.

  19. 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.

    OBJECT In patients with large or symptomatic brain lesions from metastatic melanoma, the value of resection of metastases to facilitate administration of systemic ipilimumab therapy has not yet been described. The authors undertook this study to investigate whether craniotomy creates the opportunity for patients to receive and benefit from ipilimumab who would otherwise succumb to brain metastasis prior to the onset of regression. METHODS All patients with metastatic melanoma who received ipilimumab and underwent craniotomy for metastasis resection between 2008 and 2014 at the Massachusetts General Hospital were identified through retrospective chart review. The final analysis included cases involving patients who underwent craniotomy within 3 months prior to initiation of therapy or up to 6 months after cessation of ipilimumab administration. RESULTS Twelve patients met the inclusion criteria based on timing of therapy (median age 59.2). The median number of metastases at the time of craniotomy was 2. The median number of ipilimumab doses received was 4. Eleven of 12 courses of ipilimumab were stopped for disease progression, and 1 was stopped for treatment-induced colitis. Eight of 12 patients had improvement in their performance status following craniotomy. Of the 6 patients requiring corticosteroids prior to craniotomy, 3 tolerated corticosteroid dose reduction after surgery. Ten of 12 patients had died by the time of data collection, with 1 patient lost to follow-up. The median survival after the start of ipilimumab treatment was 7 months. CONCLUSIONS In this series, patients who underwent resection of brain metastases in temporal proximity to receiving ipilimumab had qualitatively improved performance status following surgery in most cases. Surgery facilitated corticosteroid reduction in select patients. Larger analyses are required to better understand possible synergies between craniotomy for melanoma metastases and ipilimumab treatment.

    Uveal melanoma is the most common primary intraocular malignancy and the leading primary intraocular disease which can be fatal in adults. In this paper epidemiologic, pathogenetic, and clinical aspects of uveal melanoma are discussed. Despite the advance in local ocular treatments, there has been no change in patient survival for three decades. Development of metastases affects prognosis significantly. Current survival rates, factors predictive of metastatic potential and metastatic screening algorithms are discussed. Proposed and emerging treatments for uveal melanoma metastases are also overviewed. Current advances in genetics and cytogenetics have provided a significant insight in tumours with high metastatic potential and the molecular mechanisms that underlie their development. Biopsy of those lesions may prove to be important for prognostication and to allow further research into genetic mutations and potential new therapeutic targets in the future

    In patients with advanced melanoma the detection of BRAF mutations is considered mandatory before the initiation of an expensive treatment with BRAF/MEK inhibitors. Sometimes it is difficult to perform such an analysis if archival tumor tissue is not available and fresh tissue has to be collected. 514 of 1170 patients (44%) carried a BRAF mutation. All models revealed age and histological subtype of melanoma as the two major predictive variables. Accuracy ranged from 0.65-0.71, being best in the random forest model. Sensitivity ranged 0.76-0.84, again best in the random forest model. Specificity was low in all models ranging 0.51-0.55. We collected the clinical data and mutational status of 1170 patients with advanced melanoma and established three different predictive models (binary logistic regression, classification and regression trees, and random forest) to forecast the BRAF status. Up to date statistical models are not able to predict BRAF mutations in an acceptable accuracy. The analysis of the mutational status by sequencing or immunohistochemistry must still be considered as standard of care.

    The objective of this study is to analyze our experience in the use of sentinel node biopsy (SNB) in melanoma and identify the predictive factors of positive SNB and multiple drainage. Retrospective study of patients who underwent SNB for melanoma between August of 2000 and February of 2013. SNB was performed in 125 patients with a median of age of 55,6 (±15) years. The anatomic distribution was: 44 (35,2%) in legs, 24 (19,2%) in arms, 53 (42,4%) trunk and 3 (2,4%) in head and neck. The median Breslow index was 1,81 (0,45-5). Between 1 and 6 nodes were isolated. The drainage was unique in 98 (78,4%) and multiple in 27 (21,6%). The trunk was the localization of 25 (92,6%) nodes with multiple drainage. The definitive result of sentinel node (SN) was positive in 18 cases (7,1%). Breslow thickness (p=0,01) was statistically significant predictor of a positive SNB. The SNB allows patients to be selected for lymphadenectomy. Melanoma of the trunk was the principle location of multiple drainage. The only predictive factor of positive SNB was Breslow thickness.

    2013-01-01

    Full Text Available Cutaneous melanoma is an immune-dependent aggressive tumour. Up to our knowledge, there are no reports regarding immune parameters monitoring in longitudinal followup of melanoma patients. We report a followup for 36 months of the immune parameters of patients diagnosed in stages I–IV. The circulatory immune parameters comprised presurgery and postsurgery immune circulating peripheral cells and circulating intercommunicating cytokines. Based on our analysis, the prototype of the intratumor inflammatory infiltrate in a melanoma with good prognosis is composed of numerous T cells CD3+, few or even absent B cells CD20+, few or absent plasma cells CD138+, and present Langerhans cells CD1a+ or langerin+. Regarding circulatory immune cells, a marker that correlates with stage is CD4+/CD8+ ratio, and its decrease clearly indicates a worse prognosis of the disease. Moreover, even in advanced stages, patients that have an increased overall survival rate prove the increase of this ratio. The decrease in the circulating B lymphocytes with stage is balanced by an increase in circulating NK cells, a phenomenon observed in stage III. Out of all the tested cytokines in the followup, IL-6 level correlated with the patient’s survival, while in our study, IL-8, IL-10, and IL-12 did not correlate statistically in a significant way with overall survival, or relapse-free survival.

    Martinez-Rodriguez, Miguel; Thompson, Alec K; Monteagudo, Carlos

    2017-01-01

    It has been proposed that the expression of chemokines and chemokine receptors by melanoma cells may have a role in tumour immune escape. Chemokine CCL27 is reported to be expressed specifically on the epidermal keratinocytes. The implication of CCL27 in cutaneous melanomas is currently unresolved. It has been suggested that CCL27 expression in melanomas can induce antitumoral immunity, and that CCL27 may suppress tumour growth probably due to the local lymphocyte recruitment. We studied CCL27 chemokine expression in three different concentric epidermal areas covering the primary cutaneous melanoma in patients with a long clinical follow-up. Our study included 91 cases of primary melanomas of the skin diagnosed during the 10-year period 1992-2002, and a minimum clinical follow-up of 10 years. We evaluated three different concentric and easily reproducible areas in the epidermis: the area covering melanoma (which we called 'supratumoral'), the area adjacent to the tumour ('peritumoral') and the most peripheral epidermal area ('peripheral'). Only CCL27 expression in supratumoral epidermis correlated with clinical outcome. Our study showed that a higher immunostaining of CCL27 in supratumoral epidermis is associated with longer progression-free interval and melanoma-specific survival.

    The American Joint Committee on Cancer (AJCC) classification was updated to the eighth edition in January 2017, providing staging for iris melanoma. This study evaluated outcomes of iris melanoma per the AJCC classification, eighth edition. Retrospective case series. Four hundred thirty-two patients with iris melanoma. Management including tumor resection, plaque radiotherapy, or enucleation. Local tumor recurrence, melanoma-related systemic metastasis, and melanoma-related death. Of 432 patients with iris melanoma, AJCC classification was category T1 (n = 324 [75%]), T2 (n = 83 [19%]), T3 (n = 2 [iris color among T categories. Overall, Kaplan-Meier analysis of outcomes (at 5 and 10 years) revealed visual acuity reduction by 3 lines or more (42% and 54%, respectively), secondary glaucoma (29% and 33%, respectively), local recurrence (8% and 17%, respectively), secondary enucleation (12% and 19%, respectively), lymph node metastasis (1% and 1%, respectively), melanoma-related systemic metastasis (5% and 10%, respectively), and melanoma-related death (3% and 4%, respectively). Compared with T1 category, the hazard ratio (HR) for local recurrence in nonenucleated eyes was 1.31 for T2, not evaluable (NE) for T3 (because of small cohort), and 6.61 for T4; the HR for metastasis was 3.41 for T2, NE for T3 (because of small cohort), and 25.6 for T4; the HR for death was 7.51 for T2, NE for T3 (because of small cohort), and 26.5 for T4; and the odds ratio for enucleation was 1.23 for T2, 3.63 for T3, and 4.72 for T4. Features predictive of melanoma-related metastasis (multivariate analysis) included secondary glaucoma (P iris melanoma. By multivariate analysis, the ratio for melanoma-related metastasis was 4 times greater in category T2 and 31 times greater in T4 compared with T1. The ratio for melanoma-related death was 8 times greater in category T2 and 20 times greater in T4 compared with T1. The cohort size for T3 was too small to provide useful information

    2006-06-01

    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. 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. 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). 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.

    This project was initiated, in response to concerns that the observed excess of malignant melanoma among employees of Lawrence Livermore National Laboratory (LLNL) might reflect the incidence of disease diagnostically different than that observed in the general population. LLNL sponsored a slide review project, inviting leading dermatopathology experts to independently evaluate pathology slides from LLNL employees diagnosed with melanoma and those from a matched sample of Bay Area melanoma patients who did not work at the LLNL. The study objectives were to: Identify all 1969--1984 newly diagnosed cases of malignant melanoma among LLNL employees resident in the San Francisco-Oakland Metropolitan Statistical Area, and diagnosed at facilities other than Kaiser Permanente; identify a comparison series of melanoma cases also diagnosed between 1969--1984 in non-Kaiser facilities, and matched as closely as possible to the LLNL case series by gender, race, age at diagnosis, year of diagnosis, and hospital of diagnosis; obtain pathology slides for the identified (LLNL) case and (non-LLNL) comparison patients for review by the LLNL-invited panel of dermatopathology experts; and to compare the pathologic characteristics of the case and comparison melanoma patients, as recorded by the dermatopathology panel.

    Full Text Available Evolution of metastatic melanoma (MM under B-RAF inhibitors (BRAFi is unpredictable, but anticipation is crucial for therapeutic decision. Kinetics changes in metastatic growth are driven by molecular and immune events, and thus we hypothesized that they convey relevant information for decision making.We used a retrospective cohort of 37 MM patients treated by BRAFi only with at least 2 close CT-scans available before BRAFi, as a model to study kinetics of metastatic growth before, under and after BRAFi. All metastases (mets were individually measured at each CT-scan. From these measurements, different measures of growth kinetics of each met and total tumor volume were computed at different time points. A historical cohort permitted to build a reference model for the expected spontaneous disease kinetics without BRAFi. All variables were included in Cox and multistate regression models for survival, to select best candidates for predicting overall survival.Before starting BRAFi, fast kinetics and moreover a wide range of kinetics (fast and slow growing mets in a same patient were pejorative markers. At the first assessment after BRAFi introduction, high heterogeneity of kinetics predicted short survival, and added independent information over RECIST progression in multivariate analysis. Metastatic growth rates after BRAFi discontinuation was usually not faster than before BRAFi introduction, but they were often more heterogeneous than before.Monitoring kinetics of different mets before and under BRAFi by repeated CT-scan provides information for predictive mathematical modelling. Disease kinetics deserves more interest.

    The objectives of this study were to determine the cumulative incidence and timing of new brain metastases over the course of systemic therapy for metastatic melanoma and to identify prognostic factors for brain metastases. Chemo-naive patients underwent computed tomography or MRI of the brain every 6 weeks. The cumulative incidence of confirmed brain metastases was calculated at 12-week intervals. Univariable and multivariable competing risk regression models were used to assess the association between the development of brain metastases and potential risk factors of interest. Cumulative incidence with competing risk and competing risk regression was used to assess the brain metastasis-free interval from the time of diagnosis of stage IV disease. The clinical characteristics of the 315 patients with brain metastases were compared with those of 370 brain metastasis-free patients. Among patients with brain metastases, a significantly higher proportion had stage M1b and M1c disease at diagnosis compared with stage M1a and a greater proportion had metastatic disease in three or more visceral sites. Significantly shorter brain metastasis-free intervals were found in these patients compared with patients with M1a disease and those with no visceral metastases. More than 80% of the 230 patients who developed brain metastases during systemic therapy had their brain metastases confirmed within 60 weeks from the onset of advanced melanoma. Imaging studies at 12-week intervals for 60 weeks after the diagnosis of advanced melanoma will detect brain metastases in most of the patients who will eventually develop them.

    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.

  1. Proteomic Investigation of the Sinulariolide-Treated Melanoma Cells A375: Effects on the Cell Apoptosis through Mitochondrial-Related Pathway and Activation of Caspase Cascade

    Full Text Available Sinulariolide is an active compound isolated from the cultured soft coral Sinularia flexibilis. In this study, we investigated the effects of sinulariolide on A375 melanoma cell growth and protein expression. Sinulariolide suppressed the proliferation and migration of melanoma cells in a concentration-dependent manner and was found to induce both early and late apoptosis by flow cytometric analysis. Comparative proteomic analysis was conducted to investigate the effects of sinulariolide at the molecular level by comparison between the protein profiles of melanoma cells treated with sinulariolide and those without treatment. Two-dimensional gel electrophoresis (2-DE master maps of control and treated A375 cells were generated by analysis with PDQuest software. Comparison between these maps showed up- and downregulation of 21 proteins, seven of which were upregulated and 14 were downregulated. The proteomics studies described here identify some proteins that are involved in mitochondrial dysfunction and apoptosis-associated proteins, including heat shock protein 60, heat shock protein beta-1, ubiquinol cytochrome c reductase complex core protein 1, isocitrate dehydrogenase (NAD subunit alpha (down-regulated, and prohibitin (up-regulated, in A375 melanoma cells exposed to sinulariolide. Sinulariolide-induced apoptosis is relevant to mitochondrial-mediated apoptosis via caspase-dependent pathways, elucidated by the loss of mitochondrial membrane potential, release of cytochrome c, and activation of Bax, Bad and caspase-3/-9, as well as suppression of p-Bad, Bcl-xL and Bcl-2. Taken together, our results show that sinulariolide-induced apoptosis might be related to activation of the caspase cascade and mitochondria dysfunction pathways. Our results suggest that sinulariolide merits further evaluation as a chemotherapeutic agent for human melanoma.

    While the morbidity and mortality from cancer are largely attributable to its metastatic dissemination, the integral features of the cascade are not well understood. The widely accepted hypothesis is that the primary tumor microenvironment induces the epithelial-to-mesenchymal transition in cancer cells, facilitating their escape into the bloodstream, possibly accompanied by cancer stem cells. An alternative theory for metastasis involves fusion of macrophages with tumor cells (MTFs). Here we culture and characterize apparent MTFs from blood of melanoma patients. We isolated enriched CTC populations from peripheral blood samples from melanoma patients, and cultured them. We interrogated these cultured cells for characteristic BRAF mutations, and used confocal microscopy for immunophenotyping, motility, DNA content and chromatin texture analyses, and then conducted xenograft studies using nude mice. Morphologically, the cultured MTFs were generally large with many pseudopod extensions and lamellipodia. Ultrastructurally, the cultured MTFs appeared to be macrophages. They were rich in mitochondria and lysosomes, as well as apparent melanosomes. The cultured MTF populations were all heterogeneous with regard to DNA content, containing aneuploid and/or high-ploidy cells, and they typically showed large sheets (and/or clumps) of cytoplasmic chromatin. This cytoplasmic DNA was found within heterogeneously-sized autophagic vacuoles, which prominently contained chromatin and micronuclei. Cultured MTFs uniformly expressed pan-macrophage markers (CD14, CD68) and macrophage markers indicative of M2 polarization (CD163, CD204, CD206). They also expressed melanocyte-specific markers (ALCAM, MLANA), epithelial biomarkers (KRT, EpCAM), as well as the pro-carcinogenic cytokine MIF along with functionally related stem cell markers (CXCR4, CD44). MTF cultures from individual patients (5 of 8) contained melanoma-specific BRAF activating mutations. Chromatin texture analysis of

    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.

    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.

    In a compilation of nine reported series consisting of 2,024 enucleations, the five- and ten-year survivals following surgery were 63% and 43%, respectively. The 25-year survival has been reported to be 40%. In 1974 at Wills Eye Hospital and Hahnemann University, the cobalt-60 plaques technique was introduced. During the following years, other radioactive isotopes were introduced including irridium-192, iodine-125, ruthenium-106/rhodium-106 and more recently palladium-103. At the present time, iodine-125 is the most widely used radionuclide. Until now, 302 patients treated with plaque brachytherapy showed an actuarial survival of 77% and 67.8% at five and eight years, respectively. There was no significant survival difference when compared with a similar group of patients undergoing enucleation. Other retrospective studies show similar excellent results. In spite of these convincing results, the decision making process in management melanoma remains unsettled primarily due to the absence of prospective randomized trials. Because of this, the Collaborative Ocular Melanoma Study was initiated. From the standpoint of toxicity, the data are available on ocular radiation toxicity. In an analysis of 77 patients from the Wills Eye Hospital with pretreatment visual acuities of 20/25 or better, it was noted that 90% of patients who had received less than 500 Gy to the fovea retained visual acuity of 20/200 or better while only 52% of patients receiving more than 5,000 Gy to the fovea had vision of 20/200 or better. A serious late effect of radioactivity plaque treatment is scleral necrosis which may require repair or enucleation even in the absence of tumor progression. Enucleation may be necessary in approximately 10% of patients. We conclude that malignant melanoma of the uvea can be safely treated with radioactive plaques. (orig./MG) [de

    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

    Background. The survival of patients with cutaneous malignant melanoma (MM) depends on multiple factors whose role is continuously updated, as the molecular mechanisms underlying the disease progression are understood. This study intended to assess whether the patient's gender and tumor location affect the disease outcome. Methods. Between 2008 and 2012, 155 patients with cutaneous MM underwent various types of surgeries in our clinic. Patients were staged according to the 2009 TNM classification. There were 90 women and 65 men. Primary tumors were located as it follows head and neck region - 4.5%, limbs - 50.7% and trunk - 44.8%. The disease free and overall survival rates (DFS, OS) were estimated by using the Kaplan-Meier method. Results. Metastases developed in 52.3% of the males and 31.1% of the females (p=0.008). In univariate analysis, distant metastasis risk was significantly higher in men (p = 0.0472 for stage II patients and p = 0.0288 for stage III). In multivariate analysis, male gender almost doubled the risk of relapse (p = 0.044) and death (p = 0.022). Consequently, DFS and OS were significantly higher among females. Primary tumor location seemed to influence the melanoma spreading ability. Half of the trunk MM developed metastases while only a third of limbs MM did. The association between MM location and the recurrence risk was not random (p = 0.033). Conclusions. The patient gender represents an independent prognostic factor for both relapse and death. Although trunk MM had a significantly higher risk of metastasis than limbs MM, the location per se was not an independent prognostic factor for survival (p = 0.078). Abbreviations: MM = malignant melanoma, DFS = disease free survival, OS = overall survival, p = p value, AJCC = American Joint Commission on Cancer, CI = confidence interval.

    We analyzed the association of hospice use with survival and healthcare costs among patients diagnosed with metastatic melanoma. We used the Surveillance, Epidemiology, and End Results (SEER)- Medicare-linked databases to identify patients 65 years or older with metastatic melanoma who died between 2000 and 2009. We analyzed claims data to ascertain cancer treatment utilization and costs. Survival, end-of-life costs, and incremental cost-effectiveness ratio were evaluated using propensity score methods. Costs were analyzed from the payer perspective in 2009 dollars. Of 862 patients, 225 (26%) received no hospice care, 523 (61%) received 1 to 3 days of hospice care, and 114 (13%) received 4 or more days of hospice care. The median survival time was 6.1 months for patients with no hospice care, 6.5 months for patients enrolled in hospice for 1 to 3 days, and 10.2 months for patients enrolled for 4 or more days (P hospice use was 0.66; 95% confidence interval, 0.54-0.81, P hospice care incurred lower end-of-life costs than the comparison groups ($14,594 vs $22,647 for the 1-to-3-days hospice care, and $28,923 for patients with no hospice care; P hospice care had longer survival than those who had 1 to 3 days of hospice or no hospice care, and this longer overall survival was accompanied by lower end-of-life costs.

    To study radiation retinopathy after plaque radiotherapy of choroidal melanoma using optical coherence tomography angiography. Retrospective comparative analysis of 65 consecutive patients with choroidal melanoma, treated with standard dose I-125 plaque radiotherapy and imaged with optical coherence tomography angiography. A comparison of irradiated versus contralateral, nonirradiated (control) eyes was performed. The mean patient age was 55 years. Underlying medical diseases included diabetes mellitus (4/65, 4%) or hypertension (25/65, 38%), but no patient demonstrated disease-related retinopathy. The mean pretreatment melanoma diameter was 11 mm and mean thickness was 5 mm. The mean radiation dose to the foveola was 5663 centiGray. At mean follow-up of 46 months after plaque radiotherapy, the most frequent qualitative finding on optical coherence tomography angiography (irradiated eye) was nonperfusion in the superficial capillary plexus (19/65, 29%) and deep capillary plexus (20/65, 31%), followed by loss of choriocapillaris within tumor margins (11/65, 17%). The quantitative findings revealed foveal avascular zone with significantly larger mean area (irradiated vs. nonirradiated eye) in the superficial plexus (0.961 vs. 0.280 mm, P eyes without clinical evidence of radiation maculopathy (superficial 0.278 mm, P = 0.03; deep 0.454 mm, P = 0.02). Parafoveal capillary density (superficial and deep) was decreased in all irradiated eyes (P eyes with (P eyes (0.7 vs. 0.1 [Snellen equivalent 20/100 vs. 20/25], P eyes without clinical evidence of radiation maculopathy (0.4 vs. 0.1 [Snellen equivalent 20/50 vs. 20/25], P eyes after plaque radiotherapy of choroidal melanoma, even in eyes with no clinical evidence of radiation maculopathy.

    Full Text Available Introduction. Sentinel lymph node (SLN biopsy is a vital component of staging and management of multiple cancers. The current gold standard utilizes technetium 99 (tech99 and a blue dye to detect regional nodes. While the success rate is typically over 90%, these two methods can be inconclusive or inconvenient for both patient and surgeon. We evaluated a new technique using laser-assisted ICG dye lymphangiography to identify SLN. Methods. In this retrospective analysis, we identified patients with melanoma who were candidates for SLN biopsy. In addition to tech99 and methylene blue, patients received a dermal injection of indocyanine green (ICG. The infrared signal was detected with the SPY machine (Novadaq, and nodes positive by any method were excised. Results. A total of 15 patients were evaluated, with 40 SLNs removed. Four patients were found to have nodal metastases on final pathology. 100% of these 4 nodes were identified by ICG, while only 75% (3/4 were positive for tech99 and/or methylene blue. Furthermore, none of the nodes missed by ICG (4/40 had malignant cells. Conclusion. ICG dye lymphangiography is a reasonable alternative for locating SLNs in patients with melanoma. Prospective studies are needed to better ascertain the full functionality of this technique.

    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 χ(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.

    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

    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.

    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 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.

    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.

    Malignant melanoma (MM), accounts for around 10% of skin cancers. To date, there have been few data on patient satisfaction with initial management of MM. To identify the predictors of patient satisfaction with initial diagnosis and management of MM. Data on 214 patients were collected using a questionnaire filled in by a clinician during a face-to-face interview when the patient attended an appointment at a tertiary melanoma centre. Age, gender, ethnic origin, date of diagnosis, site of lesion, and overall stage at diagnosis and at interview were obtained from the hospital notes. Patients were asked about their satisfaction level at the end. In total, 64 (29.9%) patients were dissatisfied with the time they had to wait to receive a diagnosis. Patients whose initial biopsy was taken by a dermatologist were more satisfied than those whose biopsy was taken by a general practitioner (GP) (P < 0.003) and women were more dissatisfied than men (P = 0.04). Delay in diagnosis (P < 0.001) and number of visits (P < 0.001) were found to be predictors for dissatisfaction in univariate analysis, but in multivariate analysis, only the number of visits (P < 0.001) was a significant predictor of patient satisfaction. For each additional visit made by the patient, the odds of dissatisfaction increased by 3.5 times, irrespective of who did the initial biopsy, any delay in diagnosis, and the age and gender of the patient. Patients whose initial biopsy was taken by dermatologist were more satisfied than those with a biopsy taken by a GP. The number of visits was an important predictor of patient satisfaction.

Radioresistance cannot be unequivocally assumed in either case. Since deeply situated in-transit metastases cannot be destroyed by soft X-rays in spite of our good results we regard radiotherapy of invasive primary melanomas as a second choice treatment to be administered if impaired general health, excessive tumor growth in certain localisations or refusal of the patient to not allow a major operation. Nodular parts of primary melanomas should be excised before radiotherapy to obtain material for histopathological confirmation of the diagnosis and to determine the thickness of the tumor.

    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.

    Research highlights: → Strong ADAM15 expression is found in normal melanocytes. → ADAM15 expression is significantly downregulated in patients with melanoma metastasis. → TGF-β can downregulate ADAM15 expression in melanoma cells. → Overexpression of ADAM15 in melanoma cells inhibits migration, proliferation and invasion of melanoma cells. → Conclusion: ADAM15 represents an tumor suppressor protein in melanoma. -- Abstract: In a mouse melanoma metastasis model it has been recently shown that ADAM15 overexpression in melanoma cells significantly reduced the number of metastatic nodules on the lung. Unfortunately, the expression of ADAM15 in human melanoma tissue has not been determined so far. 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.

    Open inguinal lymphadenectomy for regionally metastatic melanoma is associated with a high wound-related morbidity. Videoscopic inguinal lymphadenectomy (VIL) is a minimally invasive approach with fewer wound-related complications, yet its adoption has been hindered by a lack of oncologic outcomes data. Data were prospectively collected on all VILs performed for melanoma from 2008 to 2012 (n = 40) and compared with a retrospective cohort of open superficial inguinal lymphadenectomies from 2005 to 2012 (n = 40). Continuous variables were analyzed with Student's t-test, binomial variables with chi-square, and survival curves using log-rank comparison. Median follow-up for patients undergoing VIL was 19.1 months compared with 33.9 months in the open inguinal lymphadenectomy group. There were no statistical differences in demographics (age, sex, body mass index, smoking status, Charlson comorbidity index) or clinicopathologic features (primary site, stage, Breslow depth, ulceration). Lymph node yield was similar (VIL, 12.6; open, 14.2; p = 0.131). Overall recurrence rates were also similar: 27.5% in the VIL group and 30.0% in the open group (p = 0.805). One patient in the VIL group and 2 in the open group suffered recurrence in the nodal basin. Although median survival was not reached in the VIL group, Kaplan-Meier estimates of disease-free survival (p = 0.226) and overall survival (p = 0.308) were similar. In a comprehensive analysis of wound complications including infection, skin necrosis, and seroma, patients undergoing VIL had markedly less morbidity (VIL, 47.5%; open, 80.0%; p = 0.002). Videoscopic inguinal lymphadenectomy is associated with similar oncologic outcomes and markedly reduced wound complications when compared with open inguinal lymphadenectomy. The minimally invasive procedure may be the preferred method for inguinal lymphadenectomy in melanoma. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

  12. Added clinical value of 'true' whole body F-FDG PET/CT imaging in patients with malignant melanoma

    2009-01-01

    Full text: Accurate and reliable staging of disease extent in patients with malignant melanoma is essential to ensure appropriate treatment planning. The detection of recurrent or residual malignancy after primary treatment allows for early intervention and optimises patient survival. FDG PET/CT is indicated for surveillance of malignant melanoma due to its high sensitivity and specificity for soft-tissue or nodal recurrences and metastases. It has been claimed that routinely scanning lower extremities and skull in addition to 'eyes to thigh' images in PET/CT evaluation of metastatic melanoma is warranted. Whole-body PET/CT scan reports in patients with melanoma scanned from April 2005 to December 2008 were retrospectively reviewed. PET abnormalities in the brain/scalp and lower extremities were tabulated by location and whether they were 'expected'. Findings were correlated with pathology, other imaging studies and clinical follow-up. 94 PET/CT examinations in 268 patients with melanoma were included. 9 of 294 (3.1 %) scans showed brain/scalp abnormalities, with only 4 (1.3%) showing unexpected abnormalities. 24 of 294 (8.1 %) scans showed lower extremity abnormalities, with only 5 (1.6%) showing unexpected abnormalities. In no case was an unexpected solitary malignant lesion identified in the brain/scalp or lower extremities. In patients with no known or suspected primary or metastatic melanoma involving the head or lower extremities, inclusion of these regions on PET/CT is of low yield and appears to seldom offer significant additional benefit, as detection of additional metastases in these patients is unlikely to change clinical management. Routine 'eyes to thighs' images is adequate for this subset of 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

    Full Text Available In addition to abdominal ultrasound and chest X-ray, positron emission tomography combined with computed tomography (PET/CT has been increasingly used to diagnose metastatic disease in patients with uveal melanoma. We present two clinical cases of the second malignancy (synchronous polyneoplasia, colon cancer that was eventually found during PET/CT in uveal melanoma patients performed to exclude dissemination of the neoplasm. It was shown that hybrid PET/CT is the most informative method in the diagnosis and monitoring of uveal melanoma patients. During one diagnostic procedure it enables to diagnose early stages of secondary malignancies, in addition to the assessment of metastatic dissemination.

  16. High frequency of T cells specific for cryptic epitopes in melanoma patients

    A number of cytotoxic T-cell epitopes are cryptic epitopes generated from non-conventional sources. These include epitopes that are encoded by alternative open reading frames or in generally non-coding genomic regions, such as introns. We have previously observed a frequent recognition of cryptic...... epitopes by tumor infiltrating lymphocytes isolated from melanoma patients. Here, we show that such cryptic epitopes are more frequently recognized than antigens of the same class encoded by canonical reading frames. Furthermore, we report the presence of T cells specific for three cryptic epitopes encoded...

    Few studies have examined melanoma and non-melanoma skin cancer (NMSC) incidence rates after a diagnosis of hairy cell leukaemia (HCL). We assessed 267 HCL patients treated at Memorial Sloan Kettering Cancer Center (MSKCC) and Surveillance, Epidemiology and End Results (SEER) data for melanoma and NMSC incidence rates after HCL. Incidence data from MSKCC patients demonstrated a 10-year combined melanoma and NMSC skin cancer rate of 11.3%, melanoma 4.4% and NMSC 6.9%. Molecular analysis of skin cancers from MSKCC patients revealed activating RAS mutations in 3/9 patients, including one patient with melanoma. Of 4,750 SEER patients with HCL, 55 (1.2%) had a subsequent diagnosis of melanoma. Standardized incidence ratios (SIRs) did not show that melanoma was more common in HCL patients versus the general population (SIR 1.3, 95% CI 0.78–2.03). Analysis of SEER HCL patients diagnosed before and after 1990 (approximately before and after purine analogue therapy was introduced) showed no evidence of an increased incidence after 1990. A better understanding of any potential association between HCL and skin cancer is highly relevant given ongoing trials using BRAF inhibitors, such as vemurafenib, for relapsed HCL, as RAS-mutant skin cancers could be paradoxically activated in these patients.

    Full Text Available Abstract Background We performed multicenter study to define clinical characteristics of noncutaneous melanomas and to establish prognostic factors patients who received curative resection. Methods Of the 141 patients who were diagnosed of non-cutaneous melanoma at 4 institutions in Korea between June 1992 and May 2005, 129 (91.5% satisfied the selection criteria. Results Of the 129 noncutaneous melanoma patients, 14 patients had ocular melanoma and 115 patients had mucosal melanoma. For mucosal melanoma, anorectum was the most common anatomic site (n = 39, 30.2% which was followed by nasal cavity (n = 30, 23.3%, genitourinary (n = 21, 16.3%, oral cavity (n = 14, 10.9%, upper gastrointestinal tract (n = 6, 4.7% and maxillary sinus (n = 5, 3.9% in the order of frequency. With the median 64.5 (range 4.3-213.0 months follow-up, the median overall survival were 24.4 months (95% CI 13.2-35.5 for all patients, and 34.6 (95% CI 24.5-44.7 months for curatively resected mucosal melanoma patients. Adverse prognostic factors of survival for 87 curatively resected mucosal melanoma patients were complete resection (R1 resection margin, and age > 50 years. For 14 ocular melanoma, Survival outcome was much better than mucosal melanoma with 73.3% of 2 year OS and 51.2 months of median OS (P = .04. Conclusion Prognosis differed according to primary sites of noncutaneous melanoma. Based on our study, noncutaneous melanoma patients should be treated differently to improve survival outcome.

    Treatment of advanced melanoma patients with ipilimumab results in improved survival. However, only about 20% of treated patients experience long-term benefit. Combining treatment of ipilimumab with other drugs may improve immune activation and potentially enhance clinical efficacy. The aims of the phase II clinical trial reported here were to investigate tolerability and efficacy of a combined immunotherapeutic strategy comprising standard systemic ipilimumab at 3 mg/kg four times at 3-week intervals and intratumorally injected IL-2 at 9 MIU daily twice weekly for four weeks in pretreated melanoma patients with distant metastasis. The primary endpoint was the disease control rate according to immune-related response criteria at week 12; tolerability according to Common Terminology Criteria for Adverse Events criteria was secondary endpoint. No objective responses were observed in the 15 enrolled patients. Three patients had stable disease 12 weeks after starting treatment, yielding a disease control rate of 20%. Tolerability of this combination treatment was acceptable. Observed adverse events were those expected from the respective monotherapies. Autoimmune colitis was observed in two patients. Grade III/IV adverse events were observed in 40% of patients, and no treatment-related deaths occurred. Thus, this combined immunotherapy is associated with adverse events similar to those associated with the respective monotherapies. However, this study does not provide any evidence of improved efficacy of the combination over ipilimumab alone.

    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

    Malignant melanoma (MM) prognosis has been related to tumour thickness and clinical stage and metastasis risk has been associated with presence of tumour cells in peripheral blood. The aim of this study was to determine the relationship between presence of tyrosinase in peripheral blood of MM patients and their clinical prognosis. Blood samples from 58 MM patients (stage I–IV) were analysed, using RT-PCR assay to detect tyrosinase mRNA. The results showed that positive RT-PCR assay for tyrosinase were significantly associated with clinical status and tumour thickness. After a median follow-up of 24 months, RT-PCR results were found to be significant correlated with recurrence (p < 0.05) and clinical stage III (p < 0.05). Separate analysis of stage III tumours to determine the prognostic value of tyrosinase presence in peripheral blood showed an overall 24-month survival rate of 70% in the RT-PCR negative group versus 10% in the positive group (p < 0.02). These results suggest that detection of circulating melanoma cells may be especially relevant in stage III patients, in whom RT-PCR positivity defines a subpopulation at high risk of recurrence.

    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.

    Elimination of regulatory T lymphocytes may provide a way to break self-tolerance and unleash the anti-tumor properties of circulating lymphocytes. The use of fusion proteins, which link cytotoxic molecules to receptor targets, provides one approach to this problem. This study examined the ability of a fusion protein of interleukin-2 (IL-2) and diphtheria toxin (Denileukin Diftitox, DAB389IL-2, ONTAK) to eliminate regulatory T lymphocytes based on their expression of high-affinity IL-2 receptors. Thirteen patients (12 with metastatic melanoma, 1 with metastatic renal cell carcinoma) were treated at one of the two Food and Drug Administration-approved doses of Denileukin Diftitox (seven patients at 9 microg/kg, six patients at 18 microg/kg). None of the patients experienced an objective clinical response. Foxp3 expression did not decrease significantly overall, although it did decrease minimally among patients receiving 18 microg/kg (-2.01+/-0.618 copies of Foxp3/10(3) copies of beta-actin; P=0.031). Denileukin Diftitox did not decrease the suppressive ability of CD4CD25 cells as quantified by an in vitro co-culture suppression assay. Furthermore, the increased numbers of lymphocytes in patients resulting from treatment with IL-2 were not susceptible to Denileukin Diftitox. Administration of Denileukin Diftitox does not appear to eliminate regulatory T lymphocytes or cause regression of metastatic melanoma.

    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.

    Immuntherapies are frequently accompanied by psychological side effects. Our goals were to detect the changes of psychological factors (depression, anxiety) among melanoma patients during ipilimumab treatment. Ten ipilimumab treated melanoma patients (Group 1.) and 18 low-dose interferon-alpha treated patients (Group 2.) were compared. In our longitudinal study we measured depression (Zung Self-Rating Depression Scale) and anxiety (State-Trait Anxiety Inventory, STAI). Psychological status was tested four times: in every 3 week during ipilimumab treatment according to the relevant treatment protocol and at baseline, 1st, 3rd and 6th month of interferon therapy. No significant differences were detected at different timepoints in the level of depression or in the anxiety scale in Group 1. However significant increase of depression was found in Group 2 during the 6 months of the study. Increased levels of anxiety were found in the second timepoint in both treatment groups. This increase was only temporary and the level of anxiety returned to the baseline. In our sample no measurable psychological differences were detectable during the 12 weeks treatment period of ipilimumab. Ipilimumab seems to have fewer psychological side-effects compared to other immune therapies.

    Choroidal melanoma is the most common primary malignancy of the eye, which frequently metastasizes. The Cancer Registry of Slovenia reported the incidence of choroid melanoma from 1983 to 2009 as stable, at 7.8 cases/million for men and 7.4/million for women. The aim of the retrospective study was to determinate the prognostic factors of survival for choroidal melanoma patients in Slovenia. From January 1986 to December 2008 we treated 288 patients with malignant choroidal melanoma; 127 patients were treated by brachytherapy with beta rays emitting ruthenium-106 applicators; 161 patients were treated by enucleation. Patients with tumours thickness < 7.2 mm and base diameter < 16 mm were treated by brachytherapy and had 5- and 10-year overall mortality 13% and 32%, respectively. In enucleated patients, 5- and 10-year mortality was higher, 46% and 69%, respectively, because their tumours were larger. Thirty patients treated by brachytherapy developed local recurrence. Twenty five of 127 patients treated by brachytherapy and 86 of 161 enucleated patients developed distant metastases. Patients of age ≥ 60 years had significantly lower survival in both treatment modalities. For patients treated by brachytherapy the diameter of the tumour base and treatment time were independent prognostic factors for overall survival, for patients treated by enucleation age and histological type of tumour were independent prognosticators. In first few years after either of treatments, the melanoma specific annual mortality rate increased, especially in older patients, and then slowly decreased. It seems that particularly younger patients with early tumours can be cured, whereby preference should be given to eyesight preserving brachytherapy over enucleation

    Radiotherapy with a proton beam of initial energy 55-80 MeV is presently the clinically recommended therapy for some cases of intraocular melanoma such as large melanomas or tumours adjacent to critical organs. Evaluation and optimization of radiation doses outside the treatment volume may contribute to reducing undesirable side-effects and decreasing the risk of occurrence of secondary cancers, particularly for paediatric patients. In this work the undesired doses to organs were assessed basing on Monte Carlo calculation of secondary radiation transport and on results of measurements of neutron and {gamma}-ray doses at the proton therapy facility of the Institute of Nuclear Physics at Krakow. Dosimetry was performed using a He-3-based FHT 762 neutron monitor (Wendi II), a FH40G proportional counter (for {gamma}-rays), and MTS-7 (LiF:Mg,Ti) thermoluminescence detectors (TLDs). Organ doses were calculated in the ADAM anthropomorphic phantom using the MCNPX Monte Carlo transport code and partly verified, for {gamma}-ray doses, with TLD measurements in the RANDO Anderson anthropomorphic phantom. The effective dose due to undesired radiation, including exposure from scattered radiation during the entire process of proton radiotherapy and patient positioning using X-rays, does not exceed 1 mSv.

    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.

    Thirty-seven patients with superficial spreading or nodular melanoma of the head and neck treated with irradiation are reviewed. Twenty-one patients were referred within three months of surgery. Six had an incisional biopsy followed by postoperative irradiation, 4 were locally controlled (1 dying of metastatic melanoma, 2 dying of intercurrent disease and 1 is alive and well), and 2 were not (both dead of melanoma). Fifteen patients had a local excisional biopsy (11 having tumor to the limits of the excision) followed by postoperative irradiation. Fourteen of the 15 had local control (3 had lymph node metastases and died, 3 died of distant metastases from melanoma, 7 are alive and well from 1-14 years following treatment, and one is dead of intercurrent disease), and 1 had a local recurrence and subsequently died of metastatic melanoma. Sixteen patients were irradiated for local and/or regionally recurrent disease following unsuccessful surgery, and only two were successfully controlled by irradiation and are alive and well at four and five years, respectively. Local control was 70% when a dose per fraction of greater than 400 rads was used, compared with 25% when a dose per fraction of less than 400 rads was used. It is concluded that nonlentiginous melanoma of the head and neck is not a radioresistant tumor and that local excision followed by high dose per fraction radiotherapy deserves further study in the management of melanomas of the head and neck.

    Thirty-seven patients with superficial spreading or nodular melanoma of the head and neck treated with irradiation are reviewed. Twenty-one patients were referred within three months of surgery. Six had an incisional biopsy followed by postoperative irradiation, 4 were locally controlled (1 dying of metastatic melanoma, 2 dying of intercurrent disease and 1 is alive and well), and 2 were not (both dead of melanoma). Fifteen patients had a local excisional biopsy (11 having tumor to the limits of the excision) followed by postoperative irradiation. Fourteen of the 15 had local control (3 had lymph node metastases and died, 3 died of distant metastases from melanoma, 7 are alive and well from 1-14 years following treatment, and one is dead of intercurrent disease), and 1 had a local recurrence and subsequently died of metastatic melanoma. Sixteen patients were irradiated for local and/or regionally recurrent disease following unsuccessful surgery, and only two were successfully controlled by irradiation and are alive and well at four and five years, respectively. Local control was 70% when a dose per fraction of greater than 400 rads was used, compared with 25% when a dose per fraction of less than 400 rads was used. It is concluded that nonlentiginous melanoma of the head and neck is not a radioresistant tumor and that local excision followed by high dose per fraction radiotherapy deserves further study in the management of melanomas of the head and neck

    The purpose of this study was to evaluate 18 F-FDG PET/CT scanning as an early predictor of response to immune checkpoint inhibitors (ICIs) in patients with advanced melanoma. Methods: Twenty patients with advanced melanoma receiving ICI prospectively underwent 18 F-FDG PET/CT at 3 scan intervals: before treatment initiation (SCAN-1), at days 21-28 (SCAN-2), and at 4 mo (SCAN-3). This study was approved by the institutional review board, and informed consent was received from all patients who were enrolled between April 2012 and December 2013. Tumor response at each posttreatment time point was assessed according to RECIST 1.1, immune-related response criteria, PERCIST (PERCIST 1.0), and European Organization for Research and Treatment of Cancer (EORTC) criteria. Performance characteristics of each metric to predict best overall response (BOR) at ≥ 4 mo were assessed. Results: Twenty evaluable patients were treated with ipilimumab ( n = 16), BMS-936559 ( n = 3), or nivolumab ( n = 1). BOR at ≥ 4 mo included complete response ( n = 2), partial response ( n = 2), stable disease ( n = 1), and progressive disease ( n = 15). Response evaluations at SCAN-2 using RECIST 1.1, immune-related response criteria, PERCIST, and EORTC criteria demonstrated accuracies of 75%, 70%, 70%, and 65%, respectively, to predict BOR at ≥ 4 mo. Interestingly, the optimal PERCIST and EORTC threshold values at SCAN-2 to predict BOR were >15.5% and >14.7%, respectively. By combining anatomic and functional imaging data collected at SCAN-2, we developed criteria to predict eventual response to ICI with 100% sensitivity, 93% specificity, and 95% accuracy. Conclusion: Combining functional and anatomic imaging parameters from 18 F-FDG PET/CT scans performed early in ICI appears predictive for eventual response in patients with advanced melanoma. These findings require validation in larger cohorts. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

    18 F-fluorodeoxyglucose positron emission tomography (FDG-PET)/CT is commonly used to assess tumour recurrence in high-risk patients with malignant melanoma (MM). However, results can be ambiguous either because of the CT's insufficient soft-tissue contrast or non-specific FDG accumulation caused by inflammation. Ultrasound (US) can provide additional morphologic information that is superior to CT. For precisely combining PET and US findings, we used a real-time fusion technique based on navigated US (PET/US fusion). Here, we describe our results from patients where PET/US fusion proved helpful in differentiating unclear PET/CT findings. This fusion technique is likely to be helpful for decision making in MM patients and biopsy guidance.

    Full Text Available Dermoscopy is a non-invasive procedure that allows the evaluation of cutaneous lesions, and is considered to be a useful tool that improves the diagnostic accuracy of melanoma. Many dermoscopic criteria of melanoma have been established and several algorithms have been created for melanoma detection. However, the recognition of some melanomas remains challenging. Melanomas on specific body sites, melanomas in patients with multiple atypical moles, and nodular melanomas represent the most difficult-to-recognize melanoma subtypes, since they typically lack the “classic” melanoma-specific criteria. This paper provides an update on dermoscopy of difficult-to-diagnose melanomas by summarizing the newest data. Lastly, we highlight the importance of digital dermoscopy in the follow-up of melanocytic lesions for the detection of incipient melanomas while maintaining a low excision rate.

    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

    To discuss the convenience of laser surgery as optimal treatment for melanoma of the oral mucosa. A retrospective evaluation of four patients with primary oral melanomas treated at a single Cancer Institution in Mexico City. Two patients were treated with resection of the melanoma with CO2 laser together with extraction of the involved dental organs and curettage of the alveolar walls. These two cases had melanoma in situ with multiple isolated foci. The third patient had a lesion with vertical growth, who was submitted to partial maxillectomy along with selective dissection of bilateral neck levels I-V with a negative report and the fourth patient had a history of oral nodular melanoma and presented with lymph node metastasis. According to follow-up status, there was no distant metastasis in any of the patients reported here. In our experience, conservative management with CO2 laser is adequate for melanomas of the oral mucosa with extraction of the dental organs and curettage of the alveoli to achieve complete surgical resection microscopically without sacrifice of the quality of life. Management of the neck is controversial. We recommend selective therapeutic resection of the neck only if it is found to be clinically positive. Elective dissection has not shown to have an impact in overall survival.

    The therapeutic landscape for advanced melanoma has recently been transformed by several novel agents (immune checkpoint inhibitors and molecular-targeted agents). The prospective, multi-site, observational study IMAGE (ipilimumab: management of advanced melanoma in real practice) included a retrospective cohort to describe real-world treatment prior to approval of the immune checkpoint inhibitor ipilimumab. This retrospective cohort of patients, who started second-line/subsequent treatment (index therapy) for advanced melanoma within 3 years before ipilimumab approval, was selected randomly by chart review. Collected data included treatment history, patient outcomes, and healthcare resource utilization. All patients had ≥1 year of follow-up data. This analysis included 177 patients from Europe (69%) and North America (31%). The most common index therapies (used alone or in combination) were fotemustine (23%), dacarbazine (21%), temozolomide (14%), and platinum-based chemotherapy (14%). Most patients (89%) discontinued index treatment during the study period; the most common reason was disease progression (59%). Among patients with tumor assessment (153/177; 86%), 2% had complete response, 5% had partial response, and 12% had stable disease on last tumor assessment. At 1-year study follow-up, median progression-free survival was 2.6 months (95% confidence interval [CI], 2.1-2.9) and median overall survival was 8.8 months (95% CI, 6.5-9.7). During follow-up, 95% of the patients had healthcare visits for advanced melanoma, 74% of whom were hospitalized or admitted to a hospice facility. These results provide insights into patient care with advanced melanoma in the era before ipilimumab and may serve as a benchmark for new agents in future real-world studies. © 2016 The Authors.

    Full Text Available The main cause of death among dialysis is cardiovascular. The development of atherosclerosis involves several classical risk factors such as diabetes mellitus, hypertension and dyslipidemia. Knowing their characteristics allows planning therapeutic actions aimed at reducing mortality. The aim was to characterize clinically a sample of HD patients. Forty-nine patients on HD for at least 6 months were included. Individuals with malignant disease, active inflammation, in use of omega-3 oil or anticoagulants were excluded. Clinical data were collected from medical records. Albumin, urea, creatinine, total cholesterol, triglycerides (TG, phosphorus and potassium were measured. The average age of patients (27 men and 22 women was 49.9 ± 14.3 years. The mean duration of the HD was 41.8 ± 35.9 months. About 50% were diabetic and 100% were hypertensive. Dyslipidemia was observed in 47% of patients and 51% had hypoalbuminaemia. Hyperphosphatemia was found in 77.5% and hyperkalemia was observed in 43% of patients. Negative association between TG and urea was found (r = -0.33, p = 0.03. The patients treated for a longer time for HD showed higher levels of phosphate. It is evident the presence of metabolic imbalance in patients treated for HD. Therapeutic interventions such as supplementation with omega-3 fatty acids may be important in reducing morbidity and mortality in this population.

    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

    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.

    2013-07-01

    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.

  11. A cancer vaccine induces expansion of NY-ESO-1-specific regulatory T cells in patients with advanced melanoma.

    Lisa M Ebert

    Full Text Available Cancer vaccines are designed to expand tumor antigen-specific T cells with effector function. However, they may also inadvertently expand regulatory T cells (Treg, which could seriously hamper clinical efficacy. To address this possibility, we developed a novel assay to detect antigen-specific Treg based on down-regulation of surface CD3 following TCR engagement, and used this approach to screen for Treg specific to the NY-ESO-1 tumor antigen in melanoma patients treated with the NY-ESO-1/ISCOMATRIX™ cancer vaccine. All patients tested had Treg (CD25(bright FoxP3(+ CD127(neg specific for at least one NY-ESO-1 epitope in the blood. Strikingly, comparison with pre-treatment samples revealed that many of these responses were induced or boosted by vaccination. The most frequently detected response was toward the HLA-DP4-restricted NY-ESO-1(157-170 epitope, which is also recognized by effector T cells. Notably, functional Treg specific for an HLA-DR-restricted epitope within the NY-ESO-1(115-132 peptide were also identified at high frequency in tumor tissue, suggesting that NY-ESO-1-specific Treg may suppress local anti-tumor immune responses. Together, our data provide compelling evidence for the ability of a cancer vaccine to expand tumor antigen-specific Treg in the setting of advanced cancer, a finding which should be given serious consideration in the design of future cancer vaccine clinical trials.

    Many types of cancers metastasize to the eye. However, uveal melanoma metastasizing to the contralateral choroid is very rare. We report the case of a 68-year-old man with history of treated uveal melanoma of the right eye that developed metastasis to the liver and the choroid of the left eye. Ten years earlier, he was diagnosed to have uveal melanoma of the right eye and was initially treated with plaque radiotherapy. Two years later, upon progression of the disease in the right eye he had enucleation of the eye. We describe the patient's clinical history, the diagnosis of recurrent disease in the contralateral eye, therapy of the left eye, and systemic metastasis. In addition, we reviewed the published medical literature and described the recent advances in the management of uveal melanoma.

    The incidence of melanoma of the skin has risen in Denmark in recent decades, the increase being steeper from 2004. It is unclear whether this represents a true rise in incidence or whether it is caused by an increased awareness of the condition. To assess whether the increase was characterised by early-stage melanomas and a higher proportion of melanomas with superficial spreading morphology, we studied all skin melanoma patients registered in the Danish Cancer Register 1989-2011 (n=27,010) and followed up for death through 2013. Trends in age-standardised incidence by sex, subsite and morphology, relative survival, TNM stage distribution and stage-specific relative survival from 2004 were analysed. The incidence of melanoma more than doubled over 23 years. A steeper increase from 2004 was driven mainly by superficial spreading tumours, but the proportion of nodular melanomas in patients 50 years of age and over also increased significantly. The largest increase occurred for stage I tumours and for tumours on the trunk. From 1989-1993 to 2009-2011 the 5-year relative survival increased at 12% and 6% points for male and female patients, respectively. Greater awareness, and thus lower stage at diagnosis (mediated by a large skin cancer prevention campaign from 2007), might explain part of the increase, but the increase in nodular melanoma also points to a genuine increase in the risk of melanoma.

    Full Text Available Background: Photodynamic therapy (PDT using 5-aminolevulinic acid (ALA to produce an intracellular photo-sensitizer, a protoporphyrin molecule IX (PPIX which absorbs light and targets cells, is a promising cancer treatment. Unfortunately, treatment failures are still a common occurrence when ALA is used. In this study, in order to enhance the efficacy of ALA-dependent photodynamic therapy, the effects of photodynamic therapy on melanoma cancer cells were studied after treating them with tocopherol succinate.Materials and Methods: In this experimental study melanoma cells were cultured in RPMI 1640 medium for 24 h. then, cells were treated with tocopherol succinate (6μm/ml. After 48 and 72 hours, the mediums were replaced by serum-free medium in the darkness, with ALA, 0.1mg/ml and then cells incubated for 4h. After that, cells were irradiated by using Nd: YAG laser (532 nm. After 24h, cell survival was measured by the MTT assay.Results: Twenty-four hours after PDT, among compared groups, pretreated cells with tocopherol succinate showed significant lower cell viability than control group. Conclusion: Induction of differentiation by using tocopherol succinate augmented intracellular PPIX accumulation in cells treated with ALA. Therefore phototoxic cell death after exposure to 532nm light enhances significantly in tocopherol succinate-pretreated cells. This study suggests that tocopherol succinate may act as a biological enhancer of ALA based photodynamic therapy

    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...

    To validate the Liverpool Uveal Melanoma Prognosticator Online (LUMPO) in a cohort of patients treated at the University of California-San Francisco (UCSF). A retrospective chart review was performed of 390 patients treated between 2002 and 2007 for choroidal melanoma at UCSF. Similar patients (n = 1175) treated at the Liverpool Ocular Oncology Centre (LOOC) were included in the study. The data were analyzed using the model previously developed for LUMPO, an online prognostication tool combining multiple prognostic factors. Main outcome measures included all-cause mortality and melanoma-specific mortality. Reliability of the survival estimates in each group of patients was indicated by the C-indices of discrimination and Hosmer-Lemeshow test. Patients treated at UCSF tended to be younger with thicker tumors, and were more likely to receive proton beam radiotherapy as primary treatment compared to patients at LOOC. There were no significance differences with respect to ciliary body involvement, melanoma cytomorphology, and mitotic counts between the two groups. Death occurred in 140/390 (35%) patients from UCSF and 409/1175 (34%) patients from LOOC, with no difference in overall mortality by Kaplan-Meier analysis (log rank test, P = 0.503). For all-cause mortality and melanoma-specific mortality, the C-index of discrimination and Hosmer-Lemeshow test at 5 years after treatment indicated good discrimination performance of the model, with no statistically significant difference between observed and predicted survival. Despite differences between the two cohorts, external validation in patients treated at UCSF indicates that LUMPO estimated the all-cause and melanoma-specific mortality well.

    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

    Full Text Available 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.

    Genetic findings suggesting a lower susceptibility to melanoma in patients with vitiligo are supported by recent clinical studies. Nonmelanoma skin cancer (NMSC) has also been studied, but mainly in small samples, and with conflicting results. We sought to study the relative risk (RR) of melanoma and NMSC in patients with vitiligo compared with that in patients seen for vascular surgery. The frequency of melanoma and NMSC was compared between patients with vitiligo and patients seen for vascular surgery. Occurrence of skin cancer was compared by computing RR and modeled using multiple logistic regression. Overall, the crude RR for melanoma was 0.24 (95% confidence interval [CI] 0.13-0.45) in patients with vitiligo compared with those with a nondermatologic condition (occurrence 1.1‰, 95% CI 0.5‰-2.0‰ in patients with vitiligo and occurrence 4.5‰, 95% CI 3.8‰-5.4‰ in the control cohort). The crude RR for NMSC was 0.19 (95% CI 0.14-0.17) and the occurrence was 3.8‰ (95% CI 2.7‰-5.2‰) among patients with vitiligo and 19.6‰ (95% CI 18.0‰-21.4‰) in control subjects. Patients with vitiligo who underwent phototherapy had a markedly higher risk of both cancers. In our large study, patients with vitiligo have a decreased risk of developing skin neoplasms, even considering that a larger proportion in this patient group is exposed to higher levels of ultraviolet radiation.

    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 Background/Aim. Treatment options for metastatic melanoma in Serbia are limited due to the lack of newly approved biologic agents and the lack of clinical studies. Also, there is a paucity of data regarding the treatment approaches in different tertiary centers and efficacy of available chemotherapy protocols. The aim of this study was to obtain more detailed data about treatment protocols in Serbia based on structured survey in tertiary oncology centers. Methods. Data about the melanoma patients treated in 2011 were analyzed from hospital databases in 6 referent oncology centers in Serbia, based on the structured survey, with the focus on metastatic melanoma patients (unresectable stage IIIC and IV. Results. A total of 986 (79-315 in different centers patients were treated, with 320 (32.45% newly diagnosed patients. There were 317 patients in stage IIIC/IV, 77/317 aged 60 years. At initial diagnosis 12.5% of patients were in stage III and 4.5% in stage IV. The most common type was superficial spreading melanoma (50-66%, followed by nodular melanoma (23.5-50%. Apart from the regional and distant lymph node metastases, the most frequent organs involved in stage IV disease were distant skin and soft tissues (12-55%, lungs (19-55.5%, liver (10-60%, and bones (3-10%. The first line therapy in stage IV metastatic melanoma was dacarbazine (DTIC dimethyl-triazeno-imidozole-carboxamide in 61-93% of the patients, while the second line varied between the centers. Disease control (complete response + partial response + stable disease was achieved in 25.7% of the patients treated with the first line chemotherapy and 23.1% of the patients treated with the second line therapy, but the duration of response was short, in first-line therapy 6.66 ± 3.36 months (median 6.75 months. More than 90% of patients were treated outside the clinical trials. Conclusion. Based on this survey, there is a large unmet need for the new treatment options for metastatic melanoma

    The aim of this study was to identify long non-coding RNAs (lncRNAs) which may prove useful for risk-classifying patients with melanoma. For this purpose, based on a dataset from The Cancer Genome Atlas (TCGA), we selected and analyzed samples from melanoma stages I, II, III and IV, from which differentially expressed lncRNAs were identified. The lncRNAs were classified using two-way hierarchical clustering analysis and analysis of support vector machine (SVM), followed by Kaplan-Meier survival analysis. The prognostic capacity of the signature was verified on an independent dataset. lncRNA-mRNA networks were built using signature lncRNAs and corresponding target genes. The Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis was conducted on the target genes. A total of 48 differentially expressed lncRNAs were identified, from which 6 signature lncRNAs (AL050303 and LINC00707, LINC01324, RP11-85G21, RP4-794I6.4 and RP5-855F16) were identified. Two-way hierarchical clustering analysis revealed that the accuracy of the six-lncRNA signature in risk-stratifying samples was 84.84%, and the accuracy of the SVM classifier was 85.9%. This predictive signature performed well on the validation dataset [accuracy, 86.76; area under the ROC curve (AUROC), 0.816]. A total of 720 target genes of the 6 lncRNAs were selected for the lncRNA-mRNA networks. These genes were significantly related to mitogen-activated protein kinase (MAPK), the neurotrophin signaling pathway, focal adhesion pathways, and several immune and inflammation-related pathways. On the whole, we identified a six-lncRNA prognostic signature for risk-stratifying patients with melanoma. These lncRNAs may affect prognosis by regulating the MAPK pathway, immune and inflammation-related pathways, the neurotrophin signaling pathway and focal adhesion pathways. PMID:29436619

    While locoregional cutaneous metastases (in transit and satellite) in melanoma have received little attention from researchers to date, they have pathogenic and prognostic features that distinguish them from other forms of locoregional recurrence. Identifying predictors of these metastases would be of great value for their prevention, early diagnosis, and treatment. The aim of this study was to identify the risk factors associated with locoregional cutaneous metastases as the first form of recurrence in the metastatic progression of melanoma. Between 2000 and 2010, we prospectively collected the data of 1327 patients diagnosed with stage I and II melanoma. During follow up, 112 patients (8.4%) developed metastases. Of these, 36 had exclusively locoregional cutaneous metastases. The clinical and histological characteristics of this subgroup were evaluated. In the univariate analysis, significant predictors were patient age, primary tumor thickness, site, ulceration, mitotic index, and histological type. After multivariate analysis, the independent risk factors were tumor thickness (risk ratio [RR] 5.6; 95% CI: 2.7-11.5) and the location of the primary tumor on the lower limbs (RR 3.4; 95% CI: 1.0-11.5), on the head or neck (RR 4.8; 95% IC: 1.7-13.5), or in acral sites (RR 6.7; 95% IC: 2.2-20.8). Patients who have melanomas with a Breslow thickness of more than 2mm located on the lower limbs, head, neck, or acral sites have a higher risk of developing locoregional cutaneous metastases. These findings could be useful in the design of future guidelines for the monitoring and management of melanoma. Copyright © 2012 Elsevier España, S.L. and AEDV. All rights reserved.

    Dendritic cell (DC) vaccines are currently one of the most effective approaches to treat melanoma. The immunogenicity of antigens loaded into DCs determines the treatment effects. Patients treated with autologous antigen-loaded DC vaccines achieve the best therapeutic effects. In China, most melanoma patients cannot access their autologous antigens because of formalin treatment of tumor tissue after surgery. In the present study, we purified heat shock protein 70 (HSP70)-peptide complexes (PCs) from human melanoma cell lines A375, A875, M21, M14, WM‑35, and SK‑HEL‑1. We named the purified product as M‑HSP70‑PCs, and determined its immunological activities. Autologous HSP70‑PCs purified from primary tumor cells of melanoma patients (nine cases) were used as controls. These two kinds of tumor antigenic complexes loaded into DCs were used to stimulate an antitumor response against tumor cells in the corresponding patients. Mature DCs pulsed with M‑HSP70‑PCs stimulated autologous T cells to secrete the same levels of type I cytokines compared with the autologous HSP70‑PCs. Moreover, DCs pulsed with M‑HSP70‑PCs induced CD8+ T cells with an equal ability to kill melanoma cells from patients compared with autologous HSP70‑PCs. Next, we used these PC‑pulsed autologous DCs and induced autologous specific CD8+ T cells to treat one patient with melanoma of the nasal skin and lung metastasis. The treatment achieved a good effect after six cycles. These findings provide a new direction for DC-based immunotherapy for melanoma patients who cannot access autologous antigens.

    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.

    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.

    Assess the role of SPECT-CT in sentinel lymph node (SLN) biopsy in the accurate anatomical location of the SNL in patients with cutaneous head and neck melanoma. A retrospective study was conducted from February 2010 to June 2013 on 22 consecutive patients with a diagnosis of cutaneous head and neck melanoma (9 female, 13 male), with a mean age of 55 years old and who met the inclusion criteria for SLN biopsy. Patients underwent preoperative scanning after peri-scar injection of (99m)Tc-labeled-nanocolloid. Planar images of the injection-site, whole-body, and SPECT-CT scanning were acquired. Detection rate of SLN reached up to 91% (20/22 patients) by planar lymphoscintigraphy and 95.4% (21/22 patients) by SPECT-CT. SPECT-CT provided an accurate location of SLN in 14/22 patients, enabling to improve the surgical approach (clinical impact: 63.6%). SLN was positive for metastatic cells in 9.1% patients. SPECT-CT provides detailed anatomical SLN location and allows detecting a higher number of SLN than planar lymphoscintigraphy. Routine use of SPECT-CT is recommended in order to optimise the SLN detection and location in patients with head and neck melanoma. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

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
