Incidencia y mortalidad del cáncer cutáneo en España: revisión sistemática y metaanálisis / Skin Cancer Incidence and Mortality in Spain: A Systematic Review and Meta-Analysis

INTRODUCCIÓN Y OBJETIVOS: El objetivo de la revisión sistemática es describir la incidencia y mortalidad en España del carcinoma basocelular, carcinoma espinocelular, melanoma y carcinoma de células de Merkel. MATERIAL Y MÉTODOS: Se realizó una búsqueda en Medline, Embase y revisión de artículos de la Red Española de Registros de Cáncer (REDECAN) y la Agencia Internacional de Investigación sobre el Cáncer (IARC). Se evaluó la calidad metodológica de los estudios. La heterogeneidad estadística se midió usando el estadístico I2. Para el metaanálisis de los datos se empleó un modelo de efectos aleatorios debido a la heterogeneidad de los resultados. RESULTADOS: Se incluyeron un total de 32 trabajos en la revisión sistemática. La tasa de incidencia del carcinoma basocelular global cruda fue 113,05 (IC 95%: 89,03-137,08)/100.000 personas-año para los estudios que emplean la metodología de los registros de cáncer (contando un solo tumor por persona y diagnóstico histológico). La tasa de incidencia mediante criterios clínicos e histológicos, y contando tumores en lugar de personas, fue de 253,23 (IC 95%: 273,01-269,45)/100.000 personas-año. La incidencia de carcinoma espinocelular fue de 38,16 (IC 95%: 31,72-39,97)/100.000 personas-año, de 8,76 (IC 95%: 7,50-10,02)/100.000 personas-año para el melanoma y 0,28 (IC 95%: 0,15-0,40)/100.000 personas-año para el carcinoma de células de Merkel. CONCLUSIONES: La tasa de incidencia del carcinoma basocelular y espinocelular en España está probablemente infraestimada al utilizar el método habitual de los registros. La tasa de incidencia del melanoma cutáneo es baja en comparación con otros países europeos, al igual que la tasa de incidencia del carcinoma de células de Merkel

INTRODUCTION AND OBJECTIVES: The aim of this systematic review was to describe the incidence and mortality of basal cell carcinoma, squamous cell carcinoma, melanoma, and Merkel cell carcinoma in Spain. MATERIAL AND METHODS: We performed a search of the MEDLINE and Embase databases and reviewed articles from the Spanish Network of Cancer Registries (REDECAN) and the International Agency for Research on Cancer (IARC). The methodological quality of the studies was evaluated and statistical heterogeneity was measured using the I2 index. A random-effects model was used to perform the meta-analysis because of the heterogeneity of the data. RESULTS: Thirty-two papers were included in the systematic review. The crude incidence rate for basal cell carcinoma was 113.05 (95% CI, 89.03-137.08) cases per 100 000 person-years for the studies based on the registration methodology normally used by registries (in which only 1 tumor with histological confirmation is counted per person). However, the same incidence rate calculated on the basis of clinical and histologic criteria and counting tumors rather than individual patients was 253.23 (95% CI, 273.01-269.45) cases per 100 000 person-years. The incidence was 38.16 (95% CI, 31.72-39.97) cases per 100 000 person-years for squamous cell carcinoma, 8.76 (95% CI, 7.50-10.02) cases per 100 000 person-years for melanoma, and 0.28 (95% CI, 0.15-0.40) cases per 100 000 person-years for Merkel cell carcinoma. CONCLUSIONS: The registration methodology normally used by cancer registries probably underestimates the incidence rates of basal cell and squamous cell carcinoma in Spain. The incidence rates of cutaneous melanoma and Merkel cell carcinoma are lower in Spain than in other European countries

Células madre de la piel: en la frontera entre el laboratorio y la clínica. Parte I: células madre epidérmicas / Skin Stem Cells: At the Frontier Between the Laboratory and Clinical Practice. Part 1: Epidermal Stem Cells

Las células madre son células que se caracterizan por su capacidad para autorrenovarse y diferenciarse hacia células de todos los linajes que constituyen su tejido de origen. El descubrimiento de las células madre en un organismo adulto, y la descripción de los marcadores que han permitido aislar de forma específica estas células, han abierto nuevas perspectivas y nuevos horizontes en la investigación biomédica y también nuevas esperanzas en el tratamiento de muchas enfermedades. En este artículo se revisan de forma detallada las principales características de las células madre que dan origen a las distintas células de la piel humana, incluyendo las células madre epidérmicas, mesenquimales y melanocíticas, y sus potenciales implicaciones y aplicaciones en las enfermedades cutáneas. La primera parte de este artículo revisa las células madre epidérmicas, con sus principales características y sus potenciales aplicaciones en dermatología

Stem cells are characterized by their ability to self-renew and differentiate into the different cell lineages of their tissue of origin. The discovery of stem cells in adult tissues, together with the description of specific markers for their isolation, has opened up new lines of investigation, expanding the horizons of biomedical research and raising new hope in the treatment of many diseases. In this article, we review in detail the main characteristics of the stem cells that produce the specialized cells of the skin (epidermal, mesenchymal, and melanocyte stem cells) and their potential implications and applications in diseases affecting the skin. Part I deals with the principal characteristics and potential applications of epidermal stem cells in dermatology

La linfangiogénesis. Sus implicaciones en el diagnóstico, tratamiento y pronóstico del melanoma / Lymphangiogenesis: Implications for Diagnosis, Treatment, and Prognosis in Patients With Melanoma

En pacientes con melanoma los factores pronósticos utilizados en muchas ocasiones no permiten una predicción precisa de la evolución de la enfermedad, lo que hace evidente la necesidad de búsqueda de nuevos factores pronósticos. Existe una evidencia científica cada vez más sólida de que los vasos linfáticos tumorales desempeñan un papel importante en la producción de metástasis linfáticas y también hematógenas en pacientes con melanoma. En este trabajo expondremos el estado actual del conocimiento y las implicaciones del proceso de linfangiogénesis en el diagnóstico, tratamiento y pronóstico de los pacientes con melanoma (AU)

Disease course in melanoma often cannot be accurately predicted by means of the prognostic factors usually considered in patients with melanoma; therefore, new factors are clearly needed. Increasingly robust scientific evidence shows that tumor lymph vessels play a key role in melanoma that metastasizes by lymphatic and hematogenous pathways. We review current knowledge and examine the implications of lymphangiogenesis in the diagnosis, treatment, and prognosis of patients with melanoma (AU)

Deep dermatofibrosarcoma protuberans in a ninety-year old-woman.

A 92-year-old woman was referred for the assesment of an asymptomatic subcutaneous tumor that developed after an accidental fall. The mass clinically and radiologically simulated a subcutaneous hematoma. Finally, the histological study was consistent with subcutaneous dermatofibrosarcoma protuberans.
