[Translated article] Cost of Treating Cutaneous T-Cell Lymphoma in Spain: Analysis of MICADOS Study Data by Disease Stage.

BACKGROUND AND OBJECTIVE: The cost of treating cutaneous T-cell lymphoma (CTCL) in Spain is unknown. With the advent of new treatments, it is more important than ever to gain an accurate picture of the true costs involved. The MICADOS study had 2 primary objectives: 1)to evaluate the impact of CTCL on patient quality of life, and 2)to evaluate the costs associated with the disease. This article reports the results of the cost analysis. METHODS: We estimated the cost of treating CTCL over a period of 1year from the perspective of the Spanish National Health System. Twenty-three dermatologists and hematologists from 15 public hospitals analyzed data for adult patients with mycosis fungoides (MF) or Sézary syndrome (SS). RESULTS: A total of 141 patients (57.4% male) with a mean age of 63.6 years (95%CI: 61.4-65.7 years) were included. The mean direct annual cost of treating CTCL was €34,214 per patient. The corresponding costs by stage were €11,952.47 for stageI disease, €23,506.21 for stageII disease, €38,771.81 for stageIII disease, and €72,748.84 for stageIV disease. The total direct annual cost of treating MF/SS in public hospitals in Spain was estimated at €78,301,171; stageI disease accounted for 81% of all costs, stageII for 7%, and stagesIII andIV for 6% each. CONCLUSIONS: The MICADOS study offers an accurate picture of the direct cost of treating CTCL in patients with MF/SS in Spain and shows that costs vary significantly according to disease stage. Patient-borne and indirect costs should be analyzed in future studies.

Introduction: Headaches are the most frequent neurological disorder in the pediatric population, with great impact on quality of life. This study aims to characterize a cohort of patients followed at a pediatric neurology unit between January 1st 2013 and December 31st, 2021. Materials and methods: We reviewed medical records and selected patients with primary headaches and a minimum follow-up of 12 months. Results: A total of 226 patients were included, 54.4% female, with an average age at headache onset of 9 ± 3.5 (3.1-16.5) years; 63.5% were prepubertal. A positive family history of headache was identified in 76.6% of cases and triggers in 63.6%. At first clinical assessment, 45.1% were classified as migraine without aura, 10.6% as migraine with aura, 3.5% tension-type, 8% mixed (tension and migraine), 1.3% other type and 31.4% were unclassifiable. The patients had a median follow-up of 2.4 (1.8-3.3) years. The diagnosis of tension-type headaches remained stable in 75% of the patients and resolved in 25%; 13% of the patients with migraine without aura changed into another type of headache and 17.4% resolved; 44.4% of the patients with migraine with aura turned into another type of headache and 11.1% resolved. Of the variables studied, only duration of headache episode had a significant association with headache remission, with odds ratio 0.16 (p = 0.03; 95% confidence interval: 0.032-0.84).Conclusions: Our study shows that headache type in pediatric population changes over time, especially in those with migraine with aura. The duration of each headache episode was presented as a predictor of headache remission over time.(AU)

Outcome of cutaneous squamous cell carcinoma with microscopic residual disease after surgery and usefulness of postoperative radiotherapy: a retrospective cohort study.

BACKGROUND: Microscopic residual disease (MRD) after surgery can be a challenging situation in cutaneous squamous cell carcinoma (CSCC) and there is a lack of evidence concerning its management. OBJECTIVE: To evaluate the prognosis of CSCC with MRD and the usefulness of postoperative radiotherapy (PORT) in CSCC with MRD. METHODS: Retrospective cohort study of CSCC with MRD through a 10-year period (2010-2019) (n = 244). Disease-free survival and event-free survival were assessed using R (v.3.4.1), considering competing risks. Evaluated outcomes were local recurrence (LR), nodal metastases (NMs), and disease-specific death (DSD). RESULTS: Median age was 88y (IQR: 10.5). A total of 145 (59.43%) were men and 69 (28.28%) were immunosuppressed. Median tumour diameter and thickness were 19 and 6.4 mm (IQR 11 and 5.5 mm). Patients treated by re-excision had a relapse rate of 4.3% compared with 11.30% and 29.71% in those who received PORT and observation (P = 0.045). The use of PORT was associated with a lower risk of LR compared with observation (HR = 0.206 [0.049-0.859], P = 0.030), but not with a lower risk of NMs or DSDs. In the multivariable models, PORT was again associated with a lower risk of LR than observation (HR = 0.167 [0.039-0.708], P = 0.014), but not with lower risk of metastasis and death. CONCLUSIONS: We always should try to obtain clear margins after surgery. PORT improves local control in CSCC with MRD, but when administered to the tumour bed, it does not reduce the risk of NM and DSD.

Reticular telangiectatic erythema by breast implants.

Reticular telangiectatic erythema is a benign dermatosis which has been described on patients with pacemakers, implantable devices or materials inserted in their body. Etiology of this entity hasn't been clarified since the first description in 1981 but it is suggested that physical or mechanical factors have to be involved. We present the second case of bilateral reticular telangiectatic erythema by breast implants described in the literature.

Postoperative radiotherapy provides better local control and long-term outcome in selective cases of cutaneous squamous cell carcinoma with perineural invasion.

BACKGROUND: Perineural invasion (PNI) is a feature of poor prognosis in cutaneous squamous cell carcinoma (CSCC). The benefit of postoperative radiotherapy (PORT) in the management of CSCC with PNI is still not well established. OBJECTIVES: We aimed to evaluate the usefulness of PORT in the treatment of CSCC with PNI so as to determine which patients would best benefit from this type of treatment. METHODS: A retrospective multicenter cohort of 110 CSCCs with PNI was evaluated. Eighteen recurrent cases were excluded for subsequent analysis. We searched for the types of PNI associated with poor outcome and analysed the effectiveness of PORT on different groups of CSCC with PNI. We also assessed for the usefulness of PORT depending on the surgical margin status (either clear or positive). RESULTS: Postoperative radiotherapy showed clear benefit over observation in CSCC with PNI and positive margins after surgery, where the management by observation increased the risk of poor outcome events 2.43 times (P = 0.025), and especially in those with positive margins and PNI ≥0.1 mm, where the risk of poor prognosis is eight times greater following a management by observation (P = 0.0065). Multivariate competing risk analysis preserved statistical significance. CONCLUSIONS: The use of PORT on patients with CSCC with PNI and positive margins after surgery, especially in PNI ≥0.1 mm, significantly improves long-term outcome. The benefit of PORT in cases with clear margins is not as evident, especially in those with PNI of small-calibre nerves. Clinical trials are imperative.

Rapid growth rate is associated with poor prognosis in cutaneous squamous cell carcinoma.

BACKGROUND: Cutaneous squamous cell carcinoma (cSCC) represents the most common form of skin cancer after basal cell carcinoma, and can be both locally invasive and metastatic to distant sites. Growth rate (GR) has been poorly evaluated in cSCC, despite clinical evidence suggesting that GR is an important risk factor in cSCC. AIM: To analyse the influence of GR in cSCC prognosis. METHODS: We retrospectively evaluated GR in a series of 90 cSCCs and tried to correlate GR with prognosis in cSCC. RESULTS: We demonstrated that tumours with a GR of > 4 mm/month exhibit a higher risk of nodal progression and a shorter progression time to lymph node metastasis in cSCC than those with GR of < 4 mm/month. As expected, GR correlated with tumour proliferation, as determined by Ki-67 expression. CONCLUSIONS: We consider a GR of 4 mm/month as the cutoff point that distinguishes between rapid- and slow-progressing tumours and, more importantly, to identify a subset of high-risk cSCCs.

Los nuevos sistemas de estadificación del AJCC incorporan novedades en el cáncer cutáneo / Novel Additions to the AJCC's New Staging Systems for Skin Cancer

Cuarenta años después de la publicación de la primera edición de la estadificación del American Joint Committee on Cancer, la octava edición se publica con cambios relevantes en el cáncer de piel. En el cáncer cutáneo no melanoma el American Joint Committee on Cancer mantiene un enfoque específico para el carcinoma de células de Merkel y tiene en cuenta algunos trabajos publicados recientemente sobre el pronóstico del carcinoma epidermoide cutáneo en la definición de una categoría T completamente nueva para este tumor. Por otra parte, la estadificación se contempla para el carcinoma epidermoide cutáneo de cabeza y cuello (excluyendo el párpado) y en otras localizaciones; únicamente ofrece soluciones para la estratificación de tumores de vulva, pene y región perineal. En relación con el melanoma, el valor del índice mitótico desaparece y el pronóstico del tumor primario se define basándose en el espesor de Breslow y la ulceración. Además, el espesor pasa a registrarse con una precisión de 0,1mm y aparece el concepto de T0 para los melanomas metastásicos en los que el primario ha regresado completamente. Existen diferencias en la categoría N de todos los sistemas de estadificación de cáncer cutáneo en esta nueva edición, y en relación con la categoría M, en el melanoma aparece la categoría M1d para hacer referencia a la afectación metastásica del SNC, que hasta el momento se incluía dentro de la categoría M1c. Será necesario validar este nuevo sistema con series de pacientes para valorar si efectivamente cumple con el objetivo de estratificar por riesgo los tumores de una manera adecuada (AU)

The eighth edition of the staging manual of the American Joint Committee on Cancer incorporates important changes in the classification of skin cancers. Coming 40 years after the first edition, the latest manual preserves its specific system for Merkel cell carcinoma and takes into account recent publications on the prognosis of squamous cell carcinoma by defining a completely new T category for this neoplasm. Staging for squamous cell carcinoma considers head and neck tumors (excluding the eyelid) and does not offer solutions for other sites except the vulva, penis, and perianal region. Regarding melanoma, use of the mitotic index has been eliminated and the prognosis of the primary tumor is based on Breslow thickness and ulceration. In addition, thickness is now recorded to an accuracy of 0.1mm, and the T0 concept has been introduced to define those metastatic melanomas in which the primary tumor has regressed completely. In this new edition, changes have also been made to the N category of all the skin cancer staging systems, and M1d has been added to the M category for melanoma to refer to metastatic involvement of the central nervous system, which, up to now, had been included in the M1c category. This new system will need to be validated with patient series to determine if it adequately satisfies the objective of tumor risk stratification (AU)

MicroRNA (miR)-203 and miR-205 expression patterns identify subgroups of prognosis in cutaneous squamous cell carcinoma.

BACKGROUND: Cutaneous squamous cell carcinoma (CSCC) is the second most widespread cancer in humans and its incidence is rising. These tumours can evolve as diseases of poor prognosis, and therefore it is important to identify new markers to better predict its clinical evolution. OBJECTIVES: We aimed to identify the expression pattern of microRNAs (miRNAs or miRs) at different stages of skin cancer progression in a panel of murine skin cancer cell lines. Owing to the increasing importance of miRNAs in the pathogenesis of cancer, we considered the possibility that miRNAs could help to define the prognosis of CSCC and aimed to evaluate the potential use of miR-203 and miR-205 as biomarkers of prognosis in human tumours. METHODS: Seventy-nine human primary CSCCs were collected at the University Hospital of Salamanca in Spain. We identified differential miRNA expression patterns at different stages of CSCC progression in a well-established panel of murine skin cancer cell lines, and then selected miR-205 and miR-203 to evaluate their association with the clinical prognosis and evolution of human CSCC. RESULTS: miR-205 was expressed in tumours with pathological features recognized as indicators of poor prognosis such as desmoplasia, perineural invasion and infiltrative growth pattern. miR-205 was mainly expressed in undifferentiated areas and in the invasion front, and was associated with both local recurrence and the development of general clinical events of poor evolution. miR-205 expression was an independent variable selected to predict events of poor clinical evolution using the multinomial logistic regression model described in this study. In contrast, miR-203 was mainly expressed in tumours exhibiting the characteristics associated with a good prognosis, was mainly present in well-differentiated zones, and rarely expressed in the invasion front. Therefore, the expression and associations of miR-205 and miR-203 were mostly mutually exclusive. Finally, using a logistic biplot we identified three clusters of patients with differential prognosis based on miR-203 and miR-205 expression, and pathological tumour features. CONCLUSIONS: miR-205 and miR-203 tended to exhibit mutually exclusive expression patterns in human CSCC. This work highlights the utility of miR-205 and miR-203 as prognostic markers in CSCC.

Epidermal growth factor receptor expression is associated with poor outcome in cutaneous squamous cell carcinoma.

BACKGROUND: Cutaneous squamous cell carcinoma (CSCC) is the second most frequent cancer in humans after basal cell carcinoma, and its incidence is dramatically rising. CSCC is rarely problematic, but given its high frequency, the absolute number of complicated cases is also high. It is necessary to identify molecular markers in order to recognize those CSCCs with poor prognosis. There is controversy concerning the role of epidermal growth factor receptor (EGFR) as a marker of prognosis in CSCC. In addition, EGFR-targeted therapies have emerged in recent years and a better understanding of the role of EGFR in CSCC may be of help for some patients in predicting prognosis and guiding curative management. OBJECTIVES: To evaluate the role of EGFR as a prognostic factor in CSCC. METHODS: We evaluated clinical and histopathological features, including events of poor clinical evolution, in a series of 94 cases of CSCC. We also analysed EGFR expression by immunohistochemistry, fluorescent in situ hybridization and quantitative polymerase chain reaction. RESULTS: We detected EGFR in 85 cases (90%), with overexpression in 33 cases (35%), and aberrant EGFR expression in the cytoplasm in 50 cases (53%). EGFR overexpression in the primary tumours was associated with lymph node progression, tumour-nodes-metastasis stage progression and proliferation (Ki-67 staining) in CSCC. EGFR overexpression and poor grade of differentiation were the strongest independent variables defining lymph node metastasis and progression in CSCC in a logistic regression model. CONCLUSIONS: We demonstrate that EGFR overexpression has prognostic implications associated with lymph node metastasis and progression in CSCC.

Estudio descriptivo de urgencias dermatológicas en un hospital terciario / Dermatologic emergencies in a tertiary hospital: A descriptive study

INTRODUCCIÓN: La existencia de guardias de Dermatología es escasa en nuestro sistema nacional de salud. El objetivo del presente estudio es definir cuáles son los grupos de enfermedades y afecciones dermatológicas más frecuentes que acuden a urgencias y valorar la necesidad de dichas guardias para la formación del médico interno residente (MIR). MATERIAL Y MÉTODOS: Estudio descriptivo de los pacientes que acudieron a urgencias de Dermatología durante el periodo de un año (junio de 2013-mayo de 2014), que fueron evaluados por 9 MIR de la especialidad. Las variables a estudio fueron: fecha/día, sexo, edad, diagnóstico, procedimientos quirúrgicos especiales, pruebas complementarias de laboratorio, si requirieron o no hospitalización o revisión. Además, se evaluaron los pacientes nuevos que acudieron a una consulta programada de Dermatología entre los meses de enero y junio del 2014, con el objetivo de comparar las afecciones más frecuentes en ambos grupos. RESULTADOS: Un total de 3.084 pacientes fueron atendidos en urgencias dermatológicas, que representó el 5,6% de las urgencias vistas en el hospital. Se realizaron 152 diagnósticos diferentes. Los grupos de enfermedades más frecuentes fueron: infecciosas (23%) y eccemas (15,1%). Los diagnósticos individuales fueron: urticaria aguda (7,6%), eccema de contacto (6,1%) y toxicodermias (4,6%). Ello contrasta con los diagnósticos más frecuentes en los 1.288 pacientes estudiados pertenecientes a la consulta programada (queratosis seborreica [11,9%], nevus melanocítico [11,5%] y queratosis actínica [8%]). Un 42% de los pacientes vistos en urgencias requirió revisión; los MIR de 4º año fueron los que menor número de revisiones generaron. CONCLUSIONES: En nuestro estudio el grupo de dolencias infecciosas y eccemas representan cerca del 40% del total de las consultas urgentes. Nuestros resultados parecen indicar que la realización de guardias de Dermatología por parte de los MIR de esta especialidad es de gran utilidad para el sistema hospitalario y que son necesarias en la formación integral del especialista en Dermatología

BACKGROUND AND OBJECTIVE: Dermatology in-house call is uncommon in the Spanish national health system. The objective of the present study was to define the groups of dermatologic diseases and conditions most frequently seen in the emergency department and to evaluate the need for dermatology in-house call in the training of medical residents. MATERIAL AND METHODS: We performed a descriptive study of all patients who attended the emergency department with a skin complaint during a 1-year period (June 2013 to May 2014) and were assessed by 9 dermatology residents. The study variables were date/day, sex, age, diagnosis, special surgical procedures, additional laboratory tests, and need for hospitalization and/or follow-up. We also evaluated patients attending their first scheduled visit to the dermatologist between January and June 2014 in order to compare the most frequent conditions in both groups. RESULTS: A total of 3084 patients attended the emergency room with a skin complaint (5.6% of all visits to the emergency department), and 152 different diagnoses were made. The most frequent groups of diseases were infectious diseases (23%) and eczema (15.1%). The specific conditions seen were acute urticaria (7.6%), contact dermatitis (6.1%), and drug-induced reactions (4.6%). By contrast, the most frequent conditions seen in the 1288 patients who attended a scheduled dermatology appointment were seborrheic keratosis (11.9%), melanocytic nevus (11.5%), and actinic keratosis (8%). A follow-up visit was required in 42% of patients seen in the emergency department. Fourth-year residents generated the lowest number of follow-up visits. CONCLUSIONS: We found that infectious diseases and eczema accounted for almost 40% of all emergency dermatology visits. Our results seem to indicate that the system of in-house call for dermatology residents is very useful for the hospital system and an essential component of the dermatology resident's training program

Chronic cutaneous lichenoid graft-versus-host disease at the area of herpes zoster infection and at a vaccination site.

Cutaneous graft-versus-host disease (GVHD) is a frequent complication of allogeneic bone marrow transplant and haematopoietic cell transplantation, but it is rarely presented as a Wolf's isotopic response. We report a patient who developed chronic lichenoid GVHD following the dermatomes previously affected by varicella zoster virus (VZV) infection. Nineteen months later, the same patient suffered from reactivation of GVHD at the injection site of an influenza vaccination. We review the literature concerning GVHD appearing after VZV infection and discuss the possible implications of this case and the pathogenic hypotheses.
