Melanoma prognosis in Europe: far from equal

Analysis of Risk Factors for Death from Melanoma and Genitourinary Diseases in Male Patients with Cutaneous Melanoma: A Cohort Propensity Score Matching Study

Objective

To analyze the influencing factors of male cutaneous melanoma (CM) patients dying from genitourinary diseases (GUD).

Methods

We searched the surveillance, epidemiology, and end results (SEER) database and extracted data on male CM patients according to the inclusion and exclusion criteria, including male patients whose cause of death was CM (cohort A) or GUD (cohort B). Comparisons between the two cohorts were performed before and after propensity score matching (PSM). An interaction analysis between age and year of diagnosis was also conducted. Cox regression analysis were performed to find the risk factors for death from GUD.

Results

Seven thousand seventy-eight CM patients were included, including 6415 (90.6%) in cohort A and 663 (9.4%) in cohort B. Compared with cohort A, cohort B patients were older (median age 74 ys. vs 65 ys.) and were more under the localized stage and had longer survival time no matter before or after PSM (all p<0.001). The stage was an inhibitory factor for cohort B (p <0.001). After PSM, only age and year of diagnosis were found to be cohort B's promoting factors (p<0.001). The interaction analysis showed that older patients diagnosed in later years (2009-2020) had a higher risk of dying from GUD compared to those diagnosed earlier (p<0.05). Patients with a later year of diagnosis (2009-2020) had a lower median survival time than patients with an earlier year of diagnosis (2000-2008) (p<0.001). When the patient's year of diagnosis was earlier (2000-2008), older patients (>75 ys.) had a higher risk of dying from GUD than younger patients (≤75 ys.) (p<0.001).

Conclusion

We first reported a significant interaction between age and year of diagnosis in male CM patients dying from GUD, highlighting the increased risk in older patients diagnosed more recently. We may pay attention to the possibility of dying from genitourinary diseases for CM patients.

Epidemiology and Screening for Melanoma

Melanoma is the most commonly fatal type of skin cancer, and it is an important and growing public health problem in the United States and worldwide. Fortunately, incidence rates are decreasing in young people, stabilizing in middle-aged people, and increasing in older individuals. Herein, the authors further describe trends in melanoma incidence and mortality, review the literature on risk factors, and provide an up-to-date assessment of population-wide screening and new technology being utilized in melanoma screening.

Melanoma epidemiology in Europe: what is new?

Every year in Europe over 150,000 new cases of melanoma are reported and over 25,000 lives are lost to this tumor. Incidence has been rising rapidly, faster than for any other cancer, and it is expected to continue to do so in most regions. Mortality also crept up, decades-long, with only few very recent exceptions. Thus, melanoma remains a public health problem that will not go away soon, nor easy. Some notable progress has been made in the last decade in the fight against this tumor. Registration and reporting for skin cancers improved across Europe. Incidence trends have begun to plateau or even to descend in younger age groups, in some countries, and there are encouraging signs that mortality might do the same, after the recent therapeutic breakthroughs. Survival rates are on average above 80% at 5 years for European patients, while diagnosis trends toward ever thinner tumors. Yet this progress is far from uniform across the continent, with many Southern-and Eastern European countries still struggling with sub-optimal cancer reporting, delayed access to innovative treatments, late detection and insufficient healthcare funding, that push survival rates down to harrowing 50%. This article aims to give an updated overview of the epidemiological situation of melanoma in Europe, highlighting the progress but also the persisting disparities in tumor burden, prognosis and access to quality cancer care and surveillance between European countries, as a reminder that relentless efforts must continue in order to tackle this aggressive tumor in an effective and equitable manner.

Advancing Cancer Research: Current Knowledge on Cutaneous Neoplasia

Skin cancers require a multidisciplinary approach. The updated guidelines introduce new insights into the management of these diseases. Melanoma (MM), the third most common skin cancer, a malignant melanocytic tumor, which is classified into four major histological subtypes, continues to have the potential to be a lethal disease. The mortality-incidence ratio is higher in Eastern European countries compared to Western European countries, which shows the need for better prevention and early detection in Eastern European countries. Basal cell carcinoma (BCC) and squamous cell carcinoma (cSCC) remain the top two skin cancers, and their incidence continues to grow. The gold standard in establishing the diagnosis and establishing the histopathological subtype in BCC and SCC is a skin biopsy. Sebaceous carcinoma (SeC) is an uncommon and potentially aggressive cutaneous malignancy showing sebaceous differentiation. It accounts for 0.7% of skin cancers and 3-6.7% of cancer-related deaths. Due to the rapid extension to the regional lymph nodes, SeC requires early treatment. The main treatment for sebaceous carcinoma is surgical treatment, including Mohs micrographic surgery, which has the advantage of complete margin evaluation and low recurrence rates. Primary cutaneous lymphomas (PCLs) are a heterogeneous group of lymphoproliferative diseases, with no evidence of extracutaneous determination at the moment of the diagnosis. PCLs have usually a very different evolution, prognosis, and treatment compared to the lymphomas that may secondarily involve the skin. The aim of our review is to summarize the important changes in the approach to treating melanoma, non-melanoma skin, cutaneous T and B cell lymphomas, and other types of skin cancers. For all skin cancers, optimal patient management requires a multidisciplinary approach including dermatology, medical oncology, and radiation oncology.

Smart e-Skin Cancer Care in Europe During and after the Covid-19 Pandemic: a Multidisciplinary Expert Consensus

INTRODUCTION

Melanoma is the deadliest of all the skin cancers and its incidence is increasing every year in Europe. Patients with melanoma often present late to the specialist and treatment is delayed for many reasons (delay in patient consultation, misdiagnosis by general practitioners, and/or limited access to dermatologists). Beyond this, there are significant inequalities in skin cancer between population groups within the same country and between countries across Europe. The emergence of the COVID-19 pandemic only aggravated these health deficiencies.

OBJECTIVES

The aim was to create an expert opinion about the challenges in skin cancer management in Europe during the post COVID-19 acute pandemic and to identify and discuss the implementation of new technologies (including e-health and artificial intelligence defined as "Smart Skin Cancer Care") to overcome them.

METHODS

For this purpose, an ad-hoc questionnaire with items addressing topics of skin cancer care was developed, answered independently and discussed by a multidisciplinary European panel of experts comprising dermatologists, dermato-oncologists, patient advocacy representatives, digital health technology experts, and health technology assessment experts.

RESULTS

After all panel of experts discussions, a multidisciplinary expert opinion was created.

CONCLUSIONS

As a conclusion, the access to dermatologists is difficult and will be aggravated in the near future. This fact, together with important differences in Skin Cancer Care in Europe, suggest the need of a new approach to skin health, prevention and disease management paradigm (focused on integration of new technologies) to minimize the impact of skin cancer and to ensure optimal quality and equity.

Catching Cancer Early: The Importance of Dermato-Oncology Screening

The European Society for Medical Oncology experts have identified the main components of the long-term management of oncological patients. These include early diagnosis through population screening and periodic control of already diagnosed patients to identify relapses, recurrences, and other associated neoplasms. There are no generally accepted international guidelines for the long-term monitoring of patients with skin neoplasms (nonmelanoma skin cancer, malignant melanoma, precancerous-high-risk skin lesions). Still, depending on the experience of the attending physician and based on the data from the literature, one can establish monitoring intervals to supervise these high-risk population groups, educate the patient and monitor the general population.

Melanoma Mortality Trends in 28 European Countries: A Retrospective Analysis for the Years 1960-2020

BACKGROUND

In 2020, in 27 European Union (EU) Member States, melanoma accounted for 4% of all new cancer cases and 1.3% of all cancer deaths, making melanoma the fifth most common malignancy and placing it in the 15 most frequent causes of cancer deaths in the EU-27. The main aim of our study was to investigate melanoma mortality trends in 25 EU Member States and three non-EU countries (Norway, Russia, and Switzerland) in a broad time perspective (1960-2020) in a younger (45-74 years old) vs. older age group (75+).

METHODS

We identified melanoma deaths defined by ICD-10 codes C-43 for individuals aged 45-74 and 75+ years old between 1960-2020 in 25 EU Member States (excluding Iceland, Luxembourg, and Malta) and in 3 non-EU countries-Norway, Russia, and Switzerland. Age-standardized melanoma mortality rates (ASR) were computed using the direct age-standardization for Segi's World Standard Population. To determine melanoma-mortality trends with 95% confidence intervals (CI), Joinpoint regression was applied. Our analysis used the Join-point Regression Program, version 4.3.1.0 (National Cancer Institute, Bethesda, MD, USA).

RESULTS

Regardless of the considered age groups, in all investigated countries, in general, melanoma standardized mortality rates were higher for men than women. Considering the age group 45-74, the highest number of countries was characterized by decreasing melanoma-mortality trends in both sexes-14 countries. Contrarily, the highest representation of countries in the age group 75+ was connected with increasing melanoma-mortality trends in both sexes-26 countries. Moreover, considering the older age group-75+-there was no country with a decreasing melanoma mortality in both sexes.

CONCLUSIONS

Investigated melanoma-mortality trends vary in individual countries and age groups; however, a highly concerning phenomenon-increasing melanoma-mortality rates in both sexes-was observed in 7 countries for the younger age group and in as many as 26 countries for the older age group. There is a need for coordinated public-health actions to address this issue.

Skin cancer mortality in Spain: adjusted mortality rates by province and related risk factors

BACKGROUND

Ultraviolet radiation is the main environmental risk factor responsible for the development of skin cancer. Other occupational, socioeconomic, and environmental factors appear to be related to the risk of skin cancer. Furthermore, the factors appear to differ for melanoma and non-melanoma skin cancer (NMSC). The purpose of this study is to analyze mortality rates of skin cancer in the different provinces of Spain and to determine the influence of socioeconomic conditions and other environmental and demographic factors in rates.

METHODS

Deaths from melanoma and NMSC in the period 2000-2019 were obtained as well as socioeconomic and environmental variables. Annual standardized mortality rates (SMR) were calculated for all Spanish provinces. The Pearson correlation coefficient was calculated.

RESULTS

The SMR of melanoma was 2.10/100,000 inhabitants, while that of NMSC was 1.28/100,000. At the provincial level, a great variability is confirmed. Gross domestic product showed a positive correlation with melanoma mortality but a negative correlation with NMSC. Other environmental and socioeconomic variables also showed correlation, as a positive correlation between tobacco sales and melanoma and between agricultural development and the NMSC.

CONCLUSIONS

There are still important differences between each province that must be taken into account when planning health care and resource distribution. This ecological and province-wise study helps to elucidate the relationship between social and ambient exposure determinants and skin cancer mortality in Spain.

Improving Quality Indicator of Melanoma Management - Change of Melanoma Mortality-to-Incidence Rate Ratio Based on a Hungarian Nationwide Retrospective Study

Introduction

The incidence of melanoma has been increasing in the last decades. A retrospective Hungarian epidemiological study provided real-world data on incidence and mortality rates. There have been changing trends in incidence in Hungary in the last decade and mortality decreased, shifting mortality-to-incidence rate ratios (MIR). MIR is an indicator of cancer management quality.

Objectives

Our aim is to show the changes of melanoma MIR in Hungary between 2011 and 2018 and to compare the real-world evidence-based results of our Hungarian nationwide retrospective study with other European countries.

Methods

MIR is calculated from the age-specific standardized incidence and mortality rates from our study. Annual MIR values are presented for the total population and for both sexes between 2011 and 2018, along with 95% confidence intervals. Comparison with European countries are shown for 2012 and 2018 based on the GLOBOCAN database and Eurostat health care expenditure per capita data.

Results

MIR decreased by 0.035 during the study years. The decrease was same in both sexes (0.031). Male had higher MIRs in all study years. In both 2012 and 2018, Hungarian MIR in both sexes was lower than the European Union average (males: 0.192 vs. 0.212 and 0.148 vs. 0.174 respectively, women: 0.107 vs. 0.129 and 0.083 vs. 0.107 respectively).

Discussion

Hungarian mortality-to-incidence ratio is the lowest in Central and Eastern Europe and is close to the level of Western and Northern European countries. The results are driven by the high number of new diagnosed melanoma cases.

Which medical disciplines diagnose and treat melanoma in Europe in 2019? A survey of experts from melanoma centres in 27 European countries

BACKGROUND AND OBJECTIVES

The incidence of melanoma is increasing. This places significant burden on societies to provide efficient cancer care. The European Cancer Organisation recently published the essential requirements for quality melanoma care. The present study is aimed for the first time to roughly estimate the extent to which these requirements have been met in Europe.

MATERIALS AND METHODS

A web-based survey of experts from melanoma centres in 27 European countries was conducted from 1 February to 1 August 2019. Data on diagnostic techniques, surgical and medical treatment, organization of cancer care and education were collected and correlated with national health and economic indicators and mortality-to-incidence ratio (MIR) as a surrogate for survival. Univariate linear regression analysis was performed to evaluate the correlations. SPSS software was used. Statistical significance was set at P < 0.05.

RESULTS

The MIR was lower in countries with a high health expenditure per capita and with a higher numbers of general practitioners (GPs) and surgeons (SURG) per million inhabitants. In these countries, GPs and dermatologists (DER) were involved in melanoma detection; high percentage of DER used dermatoscopy and were involved in the follow-up of all melanoma stages; both medical oncologists (ONC) and dermato-oncologists administered systemic treatments; and patients had better access to sentinel lymph node biopsy and were treated within multidisciplinary tumour boards.

CONCLUSION

Based on these first estimates, the greater involvement of GPs in melanoma detection; the greater involvement of highly trained DER in dermatoscopy, dermatosurgery, follow-up and the systemic treatment of melanoma; and the provision of ongoing dermato-oncology training for pathologists, SURG, DER and ONC are necessary to provide an optimal melanoma care pathway. A comprehensive analysis of the melanoma care pathway based on clinical melanoma registries will be needed to more accurately evaluate these first insights.

Epidemiology of Melanoma

Please add expansion for AL. Melanoma is the most common fatal type of skin cancer and is an important and growing public health problem in the United States, Australia, New Zealand, and Europe. The mortality rate in most of the world has been rising as well, albeit slower than that for incidence. Likely due to the availability of new treatments for stage 4 melanoma, mortality rates in the United States dropped 18% from 2013 to 2016. We further describe trends in melanoma incidence and mortality, review the literature on risk factors, and provide an up-to-date assessment of population-wide screening and some of the inherent concerns.

The evolving field of Dermato-oncology and the role of dermatologists: Position Paper of the EADO, EADV and Task Forces, EDF, IDS, EBDV-UEMS and EORTC Cutaneous Lymphoma Task Force

BACKGROUND

The incidence of skin cancers has been increasing steadily over the last decades. Although there have been significant breakthroughs in the management of skin cancers with the introduction of novel diagnostic tools and innovative therapies, skin cancer mortality, morbidity and costs heavily burden the society.

OBJECTIVE

Members of the European Association of Dermato-Oncology, European Academy of Dermatology and Venereology, International Dermoscopy Society, European Dermatology Forum, European Board of Dermatovenereology of the European Union of Medical Specialists and EORTC Cutaneous Lymphoma Task Force have joined this effort to emphasize the fundamental role that the specialist in Dermatology-Venereology has in the diagnosis and management of different types of skin cancer. We review the role of dermatologists in the prevention, diagnosis, treatment and follow-up of patients with melanoma, non-melanoma skin cancers and cutaneous lymphomas, and discuss approaches to optimize their involvement in effectively addressing the current needs and priorities of dermato-oncology.

DISCUSSION

Dermatologists play a crucial role in virtually all aspects of skin cancer management including the implementation of primary and secondary prevention, the formation of standardized pathways of care for patients, the establishment of specialized skin cancer treatment centres, the coordination of an efficient multidisciplinary team and the setting up of specific follow-up plans for patients.

CONCLUSION

Skin cancers represent an important health issue for modern societies. The role of dermatologists is central to improving patient care and outcomes. In view of the emerging diagnostic methods and treatments for early and advanced skin cancer, and considering the increasingly diverse skills, knowledge and expertise needed for managing this heterogeneous group of diseases, dermato-oncology should be considered as a specific subspecialty of Dermatology-Venereology.

Melanoma Epidemiology and Early Detection in Europe: Diversity and Disparities

Melanoma claims annually more than 20,000 lives in Europe and is an important public health burden through its continuously increasing incidence and with its high mortality, costs, and complexity of care in advanced stages. Epidemiological surveillance is indispensable for the research into its causes, new prognostic markers, and innovative therapies, as well as for the building of efficient cancer control plans. However, important differences in the sources and availability of accurate epidemiological data exist among European countries and regions, contributing to a heterogeneous picture with 20-fold differences in the reported national melanoma incidence rates, divergent mortality trends, and solid disparities in survival across the Continent. Countries in the eastern half of Europe report the lowest incidence rates, but high case fatality, persisting and increasing mortality, a higher proportion of thicker tumors and late diagnosis, and lower survival rates. They are the least well equipped with quality cancer registration and reporting, and they lag behind in efficient cancer control plans implementation. This review highlights the main differences in melanoma epidemiology across Europe, together with an insight into their underlying causes in the areas of melanoma registration, early diagnosis, and prevention. These differences should be acknowledged and understood by physicians, researchers, and all stakeholders involved in improving melanoma care and outcomes, as no one-size-fits-all solution can tackle the melanoma problem in Europe. Instead, there is a need for nuanced strategies, adapted to the heterogeneous national and regional contexts, that would build on European diversity to eliminate the outcome disparities.

Influence of the Exposome on Skin Cancer

Skin cancer is the most frequent type of cancer in humans. While exposure to solar radiation is the most widely known and relevant causal factor, the different degrees of individual risk have not been fully elucidated. Epidemiological studies show how the risk of skin cancer is affected by other types of radiation (eg, ionizing radiation), pesticides, particulate matter in air pollution, toxins (eg, arsenic) in water and some foods. Some living entities, such as polyomavirus and human papillomavirus, can also cause specific types of cancer. Lastly, lifestyle factors such as stress, sleep, and exercise may play a role, although only a few studies shed light on these factors. The abovementioned factors make up the exposome of skin cancer, that is, the set of environmental exposures that, together with the genome and microbiome, determine the onset of disease.

Retrospective analysis of treatment-naive Slovenian patients with metastatic melanoma treated with pembrolizumab - real-world experience

Background

Based on recent data from clinical trials, the immune checkpoint inhibitor pembrolizumab prolongs survival and has a good toxicity profile in patients with advanced or metastatic melanoma. However, the question remains whether these results are transmitted into daily clinical practice. The aim of this study was to assess the efficacy and toxicity of pembrolizumab in treatment-naive patients with metastatic melanoma in everyday clinical practice in Slovenia and compare it to the results from clinical trials.

Patients and methods

This observational retrospective cohort study included 138 consecutive metastatic treatment-naive melanoma patients treated with pembrolizumab at the Institute of Oncology Ljubljana in Slovenia, from January 2016 to December 2018. Patient and treatment characteristics were retrospectively collected from hospital data base. Statistical data was obtained using the SPSS software version 22. Survival rate was calculated with the Kaplan-Meier method. Observation period took place between January 2016 and the end of June 2019.

Results

The estimated median overall survival (OS) was 25.1 months (95% CI, 14.6–35.6) and the median progression-free survival (PFS) was 10.7 months (95% CI, 5.9–15.4). Among all patients, 29 (21.0%) achieved complete response, 31 (22.5%) partial response and 23 (16.7%) reached stable disease. The number of organs with metastatic involvement and the level of baseline lactate dehydrogenase (LDH) concentration had significant influence on survival rates. Immune-related adverse events (irAE) were reported in 88 (63%) patients, while grade 3–4 irAE occurred in 12 (8.7%). Due to toxicity, 16 (11.6%) patients discontinued the treatment.

Conclusions

Our real-world data from single centre retrospective analysis of treatment-naive metastatic melanoma patients treated with pembrolizumab showed inferior median OS and similar median PFS, compared to the results from clinical trials. However, patients with normal serum levels of LDH and a small number of organs with metastatic involvement had comparable survival outcomes. Toxicity rates of pembrolizumab were quite similar. These results further support the use of pembrolizumab for metastatic treatment-naive melanoma patients.

Psychometric assessment of the Italian version of the melanoma module (SCNS-M12-Ita) of the Supportive Care Needs Survey (SCNS-SF34)

INTRODUCTION

This study examines the validity and the reliability of the translated-into-Italian version of the SCNS-SF34 melanoma module (SCNS-M12-Ita) for a sample of patients with melanoma (n = 268).

METHODS

Content validity was analyzed by examining the redundancy of items. Floor/ceiling effects were investigated via frequency tables. Factor structure was studied through principal component analysis. Internal consistency was evaluated with Cronbach α. Test-retest reliability was analyzed using intraclass correlation coefficients (ICCs). Convergent-discriminant validity was studied by calculating Pearson correlations. Construct validity was investigated by comparing subgroups of patients through multivariate analysis of variance.

RESULTS

Content validity of the SCNS-M12-Ita was satisfactory. The floor effect ranged from 24.3% to 82.5%. The 2-factor solution explained 61.4% of the total variance. Internal consistency was excellent for component 1 (α = 0.92) and questionable (α = 0.58) for component 2. Test-retest reliability was excellent for component 1 (ICC = 0.92) and poor for component 2 (ICC = 0.58). Except for component 2, item-total correlations were greater than 0.60. Construct validity was confirmed, as the expected correlations (r < 0.40) were observed and 60% of the postulated hypotheses about between-group differences were confirmed.

CONCLUSIONS

The study demonstrated that the SCNS-M12-Ita is a valid and reliable instrument for assessing the supportive care needs of patients with melanoma.

Trends in mortality from cutaneous malignant melanoma in Spain (1982-2016): sex-specific age-cohort-period effects

BACKGROUND

Mortality from malignant cutaneous melanoma increased alarmingly during the second half of the 20th century in Spain and other European countries.

OBJECTIVE

The aim was to analyse sex- and age-specific trends in melanoma mortality in Spain in the period 1982-2016.

METHODS

European age-standardized melanoma mortality rates during the period 1982-2016 were calculated from mortality figures provided by the National Statistics Institute. Joinpoint regressions were used to identify significant points of change in trends and to compute average annual per cent change (AAPC). Age-cohort-period models were fitted to explore the effect of these variables on mortality.

RESULTS

During the period 1982-2016, age-standardized melanoma mortality rates increased in Spain from 0.90 to 1.80 deaths per 100 000 people in men and from 0.64 to 1.11 per 100 000 in women, rising noticeably from 1982 to 1995 in both sexes and in all age groups. From the mid-90s different trends were observed depending on sex and age: there was a decrease in mortality in the population younger than 45 years (AAPC -2 in both sexes) and aged 45-64 years (AAPC -1 among men and -0.2 among women), but in the group over 64 years rates continued to increase (AAPC 1.7 and 0.2, respectively, for men and women). The mortality sex ratio decreased in the younger population but increased in older individuals. A cohort effect was observed with lower mortality in the cohorts born after 1943 in men and 1956 in women. There was also a period effect with decreased mortality rates at the beginning of the 1990s.

CONCLUSIONS

Melanoma mortality rates in Spain increased during the last decades of the 20th century; however, later they stabilized in women and began to decrease in younger cohorts and middle-aged men. Promotion of primary and secondary prevention measures should continue, with particular emphasis on males over 65 years.

A 10-year retrospective study of melanoma stage at diagnosis in the academic emergency hospital of Sibiu county

Melanoma is considered to be the most aggressive skin cancer, with an increasing incidence worldwide. An accurate staging of melanoma is crucial in describing the cancer status, estimating prognosis and deciding the optimal treatment solution. In the present study, melanoma staging highlights the importance of early detection, most of the patients having been diagnosed with advanced stages of this skin cancer. A retrospective study was conducted among 117 patients of the Academic Emergency County Hospital of Sibiu, diagnosed with melanoma between 2007 and 2016. The staging of the patients with melanoma was made using the American Joint Committee on Cancer (AJCC) 7th edition, and reconsidered in the light of the AJCC 8th edition. The results showed that the majority of the cases had distant metastases, 40.17% were diagnosed with stage IV melanoma. 25.65% of the patients were diagnosed with stage III melanoma, having a regional disease. The rest of the cases had localized melanoma (stages I and II, 30.76%), while only 3.42% of them were diagnosed with melanoma in situ, the melanoma type with the greatest chances of survival. Analyzing the Breslow index, it was observed that the most common tumor thickness was 2.1 to 4 mm (34.19%). In conclusion, as the incidence of melanoma increases in Romania, further efforts are needed to improve the early detection of melanoma. There are hopes that with the correct and early diagnosis of melanoma, the mortality rate of this neoplasm will decrease in the future.

Melanoma prognosis in the United States: Identifying barriers for improved care

BACKGROUND

Despite improvements in melanoma mortality, disparities in melanoma survival persist. We evaluated possible sociodemographic and health care-based predictors of differences in melanoma survival in the United States by using the melanoma mortality-to-incidence ratio (MIR).

METHODS

State-based MIRs were calculated by using US cancer statistics data from 1999 to 2014. Pearson correlations and linear regressions were used to determine associations between MIR and dermatologist density, primary care provider density, number of physicians by state, number of National Cancer Institute-designated cancer centers, health care spending per capita, average household income, racial/ethnic makeup of the population, percentage of uninsured individuals, and percentage with a bachelor's degree.

RESULTS

The mean overall MIR was 0.15 ± 0.04; only Alaska was an outlier (0.24). No state MIRs increased significantly over time; MIR decreased for most states. Multivariable analysis revealed that states with more active physicians (P = .02) and a higher percentage non-Hispanic whites (P = .004) had higher MIRs (poorer survival). Significant Pearson correlations were seen between MIR and melanoma incidence (r = -0.72, P < .001), melanoma mortality (r = 0.38, P < .001), dermatologist density (r = 0.32, P < .001), and National Cancer Institute-designated cancer center count (r = -0.12, P = .001).

CONCLUSIONS

Melanoma survival is improved in higher-incidence areas and areas with higher dermatologist density. These findings highlight areas of poorer melanoma survival and the need for local studies evaluating disparities in melanoma survival.

Quality assurance in melanoma care: The EU-MELACARE study

BACKGROUND

A significant disparity regarding survival outcome for melanoma among European regions is well recognized and access to high quality care for European melanoma patients needs to be improved. There is an unmet need for the implementation of minimal standard of care within defined clinical pathways and Quality Assurance (QA) indicators.

OBJECTIVE

The EU-MELACARE study aims to identify shared variables for cutaneous melanoma cases recorded in melanoma registries across Europe.

MATERIAL AND METHODS

Opinion leaders involved in melanoma data registration and care quality analysis in 34 European countries were invited to respond to an expert survey covering questions regarding the melanoma registration practice in their countries and the characteristics, coverage and variables collected by the relevant melanoma registries.

RESULTS

Data regarding 13 melanoma registries from 11 European countries contributed to the study. The majority (61,5%) were population based registries and more than half (62%) had national coverage. The included registries collected a median of 38 variables (Interquartile Range, IRQ 21-76). We identified 24 shared variables available in >70% of registries.

CONCLUSIONS

This study provides valuable specific information on information recorded for melanoma cases are registered within Europe. A core of shared variables has been identified, which will constitute the basis for a standardized set of QA indicators for assessing and monitoring melanoma care across European countries.

Access to innovative medicines for metastatic melanoma worldwide: Melanoma World Society and European Association of Dermato-oncology survey in 34 countries

According to data from recent studies from Europe, a large percentage of patients have restricted access to innovative medicines for metastatic melanoma. Melanoma World Society and European Association of Dermato-oncology conducted a Web-based survey on access to first-line recommended treatments for metastatic melanoma by current guidelines (National Comprehensive Center Network, European Society for Medical Oncology [ESMO] and European Organization for Research and Treatment of Cancer/European Association of Dermato-oncology/European dermatology Forum) among melanoma experts from 27 European countries, USA, China, Australia, Argentina, Brazil, Chile and Mexico from September 1st, 2017 to July 1st, 2018. Data on licencing and reimbursement of medicines and the number of patient treated were correlated with the data on health expenditure per capita (HEPC), Mackenbach score of health policy performance, health technology assessment (HTA), ASCO and ESMO Magnitude of clinical benefit scale (ESMO MCBS) scores of clinical benefit and market price of medicines. Regression analysis for evaluation of correlation between the parameters was carried out using SPSS software. The estimated number of patients without access in surveyed countries was 13768. The recommended BRAFi + MEKi combination and anti-PD1 immunotherapy were fully reimbursed/covered in 19 of 34 (55.8%) and 17 of 34 (50%) countries, and combination anti-CTLA4+anti-PD1 in was fully covered in 6 of 34 (17.6%) countries. Median delay in reimbursement was 991 days, and it was in significant correlation with ESMO MCBS (p = 0.02), median market price (p = 0.001), HEPC and Mackenbach scores (p < 0.01). Price negotiations or managed entry agreements (MEAs) with national authorities were necessary for reimbursement. In conclusion, great discrepancy exists in metastatic melanoma treatment globally. Access to innovative medicines is in correlation with economic parameters as well as with healthcare system performance parameters. Patient-oriented drug development, market access and reimbursement pathways must be urgently found.

ECCO essential requirements for quality cancer care: Melanoma

BACKGROUND

ECCO essential requirements for quality cancer care (ERQCC) are explanations and descriptions of challenges, organisation and actions that are necessary to give high-quality care to patients who have a specific type of cancer. They are written by European experts representing all disciplines involved in cancer care. ERQCC papers give oncology teams, patients, policymakers and managers an overview of the elements needed in any healthcare system to provide high quality of care throughout the patient journey. References are made to clinical guidelines and other resources where appropriate, and the focus is on care in Europe.

MELANOMA

ESSENTIAL REQUIREMENTS FOR QUALITY CARE: CONCLUSION: Taken together, the information presented in this paper provides a comprehensive description of the essential requirements for establishing a high-quality service for melanoma. The ERQCC expert group is aware that it is not possible to propose a 'one size fits all' system for all countries, but urges that access to multidisciplinary teams and specialised treatments is guaranteed to all patients with melanoma.

Microvessel Density in Patients with Cutaneous Melanoma: An Up-to-Date Systematic Review and Meta-Analysis

Background

We conducted a meta-analysis, in order to appraise the effect of microvessel density (MVD) on the survival of patients with cutaneous melanoma.

Methods

This study was conducted according to the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. A systematic literature search in electronic databases (MEDLINE, Web of Science, and Cochrane Central Register of Controlled Clinical Trials) was performed. Fixed Effects or Random Effects model was used, based on the Cochran Q test.

Results

In total 9 studies (903 patients) were included. Pooled HR for overall survival (OS) and disease-free survival (DFS) were 2.62 (95% CI: 0.71–9.60, p = 0.15) and 2.64 (95% CI: 0.82–8.47, p = 0.10), respectively. Odds ratios of overall survival between high and low MVD groups, at 12 (1.45, 95% CI: 0.16–13.24), 36 (2.93, 95% CI: 0.63–13.59), and 60 (4.09, 95% CI: 0.85–19.77) months did not reach statistical significance. Significant superiority of low MVD group, in terms of DFS, at all time intervals (OR: 4.69, p < 0.0001; OR: 2.18, p = 0.004; OR: 7.46, p = 0.01, resp.) was documented.

Discussion

MVD does not affect the HR of OS and DFS. A strong correlation with DFS rates at 12, 36, and 60 months was recorded.

Malignant melanoma incidence trends in a Mediterranean population following socioeconomic transition and war: results of age-period-cohort analysis in Croatia, 1989-2013

The aim of this study was to analyse trends of malignant melanoma incidence in Croatia for men and women of different age groups by birth cohorts and time periods, and to interpret them in the context of national socioeconomic changes over time and the possible implications for future prevention in South-Eastern European postcommunist countries with high mortality rates. We used the Croatian National Cancer Registry data to analyse incidence trends of malignant melanoma of the skin (ICD-9 code 172 and ICD-10 code C43) in men and women aged 25-79 years by age-period-cohort modelling. Over the 25-year period, the incidence was increasing by 5.0% annually in men and 4.6% in women. The age-period model provided the best fit for data in both sexes, with steeply increasing incidence rates, followed by a stabilization after the 2000s. On the cohort scale, incidence rates increased in successive generations of men, whereas in women, the risk of malignant melanoma attenuated in recent cohorts. Even if some progress has been achieved in recent years, the increasing melanoma incidence without concomitant declines in mortality would indicate a need to rekindle prevention efforts in the country taking the specific socioeconomic context into account.

Cancer registries in Europe-going forward is the only option

Cancer registries (CR) are the fundamental source of objective cancer data, and thus are indispensable for the evaluation of the cancer burden and for design of effective cancer control plans. Their potential roles spread far beyond epidemiological research, from the exploration of the causes of cancer to health economics, from the evaluation of mass screening programmes to monitoring the quality and outcomes of health services, from addressing the inequalities in access to healthcare, to patients' quality of life analyses, from treatment safety to the development of biomarkers. In Europe, cancer registration is challenged by significant disparities in the quality and coverage of CRs, by insufficient harmonisation and comparability of procedures and data, by heterogeneous legislation that limits CR's abilities for networking, collaboration, and participation in research. These arise against the background of large variations in economical, regulatory, social, and cultural national contexts. Important steps have been taken at European Union (EU)-level in recent years towards mapping and understanding these challenges, identifying best practices and formulating sensible recommendations, and creating the policy frameworks and the tools for cooperation and information sharing. Yet, as cancer has now become the second cause of death in Europe, one third of the population still lacks quality cancer registration, mostly in the regions with lowest resources and health status. It is therefore imperative that the efforts to support the development of CRs continue, and that the wealth of knowledge and vision acquired in this area is transformed into action.

Sun Exposure Prevalence and Associated Skin Health Habits: Results from the Austrian Population-Based UVSkinRisk Survey

Recreational sun exposure accounts for a large number of acute and chronic dermatological diseases, including skin cancer. This study aimed at estimating the one-year prevalence of sun exposure and skin health-associated knowledge and attitudes among Austrian citizens. The population-based UVSkinRisk survey investigated a representative sample of Austrian adults using a structured questionnaire. In total, 1500 study subjects (median age 33.0 years, 50.5% females) participated in this questionnaire survey. Among study participants, prevalence of sun exposure was 47%, with slightly higher rates in males (48%) compared to females (46%). Younger age, lower professional category, darker skin type, motives to tan, sunbed use, sunburn, and outdoor sport activity increased the odds for prevalent sun exposure. This is the first population-based study evaluating the prevailing sun exposure and recreational habits influencing skin health among Austrian citizens. Despite public media campaigns educating on the harmful effects of sunlight exposure, we found a high prevalence of self-reported sunlight exposure. The results suggest that multifaceted socio-cultural characteristics stimulate recreational sun exposure and tanning habits. Communicating individualized Public (Skin) Health messages might be the key to prevent photo-induced skin health hazards in light-skinned populations. The practical and theoretical implications of these findings are discussed.

Gender aspects of recreational sun-protective behavior: results of a representative, population-based survey among Austrian residents

PURPOSE

Lifetime risk for melanoma skin cancer is enlarged by sunlight exposure and reduced by sun protection. Austrian melanoma incidence and mortality rates are constantly rising with higher rates in males. Thus, we aimed at investigating gender-specific recreational sun exposure habits among the Austrian population.

METHODS

We conducted a telephone survey among 1500 adults (50.5% females) representing sociodemographic characteristics of the Austrian population. Using a structured questionnaire, we studied gender-specific sun exposure-related knowledge, motives to tan, and behavior.

RESULTS

Overall, using sunscreen, wearing sunglasses, and seeking shade were among the three most frequent sun safe measures. Basic skin health knowledge and tanning motives were similar among genders, although females protected themselves more. In general, sunburn occurrence (odds ratio [OR] = 1.4, 95% confidence interval [CI] = 1.0-1.8), skin type IV (OR = 2.4, 95% CI = 1.3-4.5), ex-/non-smoking (OR = 1.4-1.6, 95% CI = 1.0-2.1), low motives to tan (both OR = 1.3, 95% CI = 1.0-1.7), no outdoor sport (OR = 1.3, 95% CI = 1.0-1.7), all P < 0.05, as well as the use of sunscreen with lower SPF values (OR = 1.0-3.0, 95% CI = 1.4-4.3) and male gender (OR = 1.6, 95% CI = 1.2-2.0), both P < 0.001, increased the odds of practicing low sun protection.

CONCLUSION

The results of this investigation suggest considering gender specificity when planning Public (Skin) Health-related educative campaigns and programs, for example, by highlighting the appearance-related benefits of sun light avoidance.

Mitochondrial DNA copy number in peripheral blood and melanoma risk

Mitochondrial DNA (mtDNA) copy number in peripheral blood has been suggested as risk modifier in various types of cancer. However, its influence on melanoma risk is unclear. We evaluated the association between mtDNA copy number in peripheral blood and melanoma risk in 500 melanoma cases and 500 healthy controls from an ongoing melanoma study. The mtDNA copy number was measured using real-time polymerase chain reaction. Overall, mean mtDNA copy number was significantly higher in cases than in controls (1.15 vs 0.99, P<0.001). Increased mtDNA copy number was associated with a 1.45-fold increased risk of melanoma (95% confidence interval: 1.12-1.97). Significant joint effects between mtDNA copy number and variables related to pigmentation and history of sunlight exposure were observed. This study supports an association between increased mtDNA copy number and melanoma risk that is independent on the known melanoma risk factors (pigmentation and history of sunlight exposure).

Epidemiological and genetic factors underlying melanoma development in Italy

Among human cancers, melanoma remains one of the malignancies with an ever-growing incidence in white populations. Recent advances in biological and immunological therapeutic approaches as well as increased efforts for secondary prevention are contributing to improve the survival rates. It is likely that a significant fall in mortality rates for melanoma will be achieved by further increase of the early detection through a more accurate selection of the higher-risk individuals (i.e., carriers of predisposing genetic alterations). A similar scenario occurs in Italy. In the present review, we have considered data on incidence, survival and mortality rates of melanoma in Italian population, including evaluation of the main risk factors and genetic mutations underlying disease susceptibility.

Delayed presentation of a metastatic choroidal melanoma to the liver: The latency of an elective metastatic localization

INTRODUCTION

Choroidal melanoma is the most common primary intraocular malignant tumour and the second most common type of primary malignant melanoma in the body. Biologically, cutaneuous and ocular melanoma may be considered different, in terms of both metastatic diffusion and metastatic latency. The principal target organ for metastasis of the ocular melanoma is the liver.This distinctive behaviour is also sustained by different metastatic latency, as some patients present with metastatic ocular melanoma several years after the treatment of the primary tumor.

PRESENTATION OF CASE

A 60 year-old male who had undergone left ocular enucleation for choroid melanoma 20 years ago was referred to our department with a three months history of diffuse abdominal pain, fever, weight loss and massive ascites. Abdominal ultrasonography (US) and total body computed tomography (CT) scan were performed and revealed diffuse liver metastases, associated with peritoneal carcinosis, bilateral adrenal metastases and a large mass in the left kidney compatible with another secondary localization. An ultrasound guided fine needle agobiopsy (FNA) of liver lesions was performed and the pathological findings led to the diagnosis of liver metastasis from choroidal melanoma. The patient died a few weeks later for hepatic failure.

DISCUSSION

Currently, there is no consensus regarding the optimal follow-up in terms of screening modality or time interval after the treatment of the primary ocular melanoma.

CONCLUSION

Patients with gastrointestinal symptoms and a history of choroidal melanoma should be investigated for the presence of gastrointestinal or liver metastases, although the original primary malignancy was diagnosed years before the patient's presentation.

[What's new in skin cancers?]

The present "what's new in oncology in 2014?" is in keeping with data reported in the past years. Indeed, metastatic melanoma still keeps the lion's share. The results of the combinations schedules with BRAF and MEK inhibitors showed an improvement in progression-free survival. Otherwise, resistance mechanisms to MAPKinase pathway inhibitors are of interest worldwide. Nevertheless, more fundamental and transversal researches are currently being investigated than validated schedules in daily clinical practice. Following anti-CTLA-4 drugs, second-generation immunotherapies, including anti-PD1 and PD-L1 molecules, confirmed their results in extended cohorts. In the setting of localized melanoma, the final results from MLST-1, Morton's study, regarding the sentinel node procedure versus observation alone, prompted a new enhancement in the sentinel node controversy. From another point of view, "what is not new in oncology in 2014?" In this area, the absence of original investigations on the primary melanoma detection in France and the absence of innovations in the adjuvant treatment of melanoma after surgery should be mentioned. While recent revolutionary drugs, i.e. targeted therapies and immunotherapies, will know advances under the resistance pressure in a near future, a revolution is still awaited in melanoma earlier stages.
