Risk of a Second Skin Cancer in a Cohort of Patients With Nonmelanoma Skin Cancer -Basal Cell Carcinoma or Squamous Cell Carcinoma-Treated With Mohs Micrographic Surgery: A National Prospective Cohort Study. / Riesgo de aparición de segundas neoplasias cutáneas en una cohorte de pacientes diagnosticados de carcinoma queratinocítico (carcinoma basocelular y carcinoma epidermoide) tratados con cirugía de Mohs. Estudio de cohortes prospectivo nacional.

OBJECTIVE: Patients with nonmelanoma skin cancer (NMSC)-ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)-have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS). MATERIAL AND METHODS: Prospective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression. RESULTS: We analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9). CONCLUSION: Patients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex.

Systemic Treatment of Moderate to Severe Psoriasis in Pediatric Patients in Galicia, Spain: A Descriptive Study. / Tratamiento sistémico de la psoriasis moderada-grave en edad pediátrica en Galicia: estudio descriptivo.

BACKGROUND AND OBJECTIVE: Studies on the use of systemic therapy for psoriasis in pediatric patients are scarce. The main aim of this study was to describe the systemic treatments used for moderate to severe psoriasis in pediatric clinical settings. The second aim was to describe the effectiveness and safety of these treatments. MATERIAL AND METHODS: Descriptive, cross-sectional, multicenter study of patients under 18 years of age with moderate to severe psoriasis who were being treated or had been treated with a systemic drug (conventional or biologic) or phototherapy. We recorded demographic and clinical information, treatments received, tolerance, adverse effects, and response to treatment. RESULTS: Data were collected for 40 patients (60% female; mean age, 13 years) who had received 63 treatments in total. The most common first treatment (n=40) was phototherapy (administered to 68% of patients), followed by acitretin (15%). The most common treatments overall (n=63) were phototherapy (57%) and methotrexate (16%). At week 12 (evaluation of systemic treatment and phototherapy), 66% of the patients were classified as good responders and 22% as partial responders. The respective rates for week 24 (evaluation of systemic treatment only) were 36% and 32%. The treatments were well tolerated (97%) and adverse effects were reported in just 11% of cases. There were no treatment discontinuations because of adverse effects. CONCLUSIONS: Phototherapy, followed by methotrexate, was the most common treatment for moderate to severe psoriasis in this series of patients under 18 years. The treatments showed a favorable safety profile and were associated with a good response rate of 66% at week 12 (systemic treatment and phototherapy) and 36% at week 24 (systemic treatment only).

Tratamiento sistémico de la psoriasis moderada-grave en edad pediátrica en Galicia: estudio descriptivo / Systemic Treatment of Moderate to Severe Psoriasis in Pediatric Patients in Galicia, Spain: A Descriptive Study

ANTECEDENTES Y OBJETIVO: Los trabajos sobre el tratamiento sistémico de la psoriasis en edad pediátrica son escasos. El objetivo principal de este trabajo consistió en describir qué tratamientos sistémicos se emplean en práctica clínica en psoriasis moderada-grave en edad pediátrica. Secundariamente se describió la efectividad y perfil de seguridad de dichos tratamientos. MATERIALES Y MÉTODOS: Estudio descriptivo transversal multicéntrico, de los pacientes con psoriasis moderada-grave, que siendo menores de 18 años estuviesen recibiendo o hubieran recibido tratamiento sistémico (clásico o biológico) o fototerapia. Se recogieron datos clínico-demográficos, tipo de tratamiento recibido, y tolerancia, efectos indeseables y respuesta al mismo. RESULTADOS: Se obtuvieron datos de 40 pacientes (60% sexo femenino, edad media 13 años), que realizaron 63 ciclos de tratamiento. Teniendo en cuenta el primer tratamiento (n = 40), la fototerapia fue la opción más frecuente (68%), seguida de acitretino (15%). Considerando el total de ciclos de tratamiento (n = 63), el tratamiento más frecuentemente empleado fue la fototerapia (57%), seguida de metotrexato (16%). En la semana 12 (incluye evaluación de fototerapia), el 66% y el 22% fueron buenos respondedores o respondedores parciales, respectivamente. En la semana 24 (datos exclusivos sobre fármacos sistémicos), el 36% y el 32% continuaron con respuestas buenas y parciales. Los tratamientos fueron bien tolerados (97%) y los efectos indeseables escasos (11%), sin que en ningún caso motivasen la suspensión del fármaco. CONCLUSIONES: En la población menor de 18 años con psoriasis moderada-grave evaluada la fototerapia fue el tratamiento más utilizado, seguida de metotrexato. Los tratamientos consiguieron porcentajes de buenos respondedores del 66% en la semana 12 (incluida fototerapia), y del 36% en la semana 24 (fármacos sistémicos sin fototerapia), presentando un buen perfil de seguridad

Descripción de pacientes no aptos para ser sometidos a cirugía de Mohs tras valoración prequirúrgica: datos del registro español Regesmohs / Description of patients excluded for Mohs surgery after pre-surgical evaluation: data from the Regesmohs Spanish registry

ANTECEDENTES: El registro Regesmohs es un registro de ámbito nacional, de pacientes evaluados y sometidos a una cirugía de Mohs, en 17 centros españoles, desde julio de 2013. Como la cirugía de Mohs es el tratamiento que mejores resultados da para el manejo del carcinoma de células basales (CCB) de alto riesgo y otros tumores de la piel, queríamos describir los motivos por los que algunos pacientes fueron considerados no aptos para ser sometidos a este tratamiento y qué tratamientos alternativos recibieron. Estos datos pueden ser útiles para evitar excluir a pacientes aptos para ser sometidos a una cirugía de Mohs, para calcular la demanda que estos pacientes generan a nivel sanitario, así como la demanda que hay de tratamientos de inhibidores de la vía de Hedgehog en dicho grupo de pacientes. OBJETIVO: Describir a aquellos pacientes que fueron considerados no aptos para ser sometidos a una cirugía de Mohs tras valoración prequirúrgica y los tratamientos que recibieron. MÉTODOS: Regesmohs incluye a todos los pacientes consecutivos para ser sometidos a una cirugía de Mohs en los centros participantes, recogiendo datos sobre las características de los pacientes, las intervenciones y los resultados a corto y largo plazo. Se hizo una descripción de los pacientes considerados no aptos para ser sometidos a una cirugía de Mohs tras valoración prequirúrgica. RESULTADOS: Tres mil once pacientes fueron incluidos en el registro Regesmohs entre julio de 2013 y octubre de 2016. En 85 pacientes no se realizó cirugía de Mohs porque se consideraron candidatos inadecuados. Sesenta y siete pacientes presentaban CCB. Las razones para ser considerado paciente no apto fueron: contraindicaciones médicas (27,1%, n = 23), tumores de bajo riesgo (18,8%, n = 16) y tumores gigantes e invasión ósea (15,3%, n = 13). Solo un paciente (1,2%) reveló compromiso de ganglios linfáticos y ningún paciente metástasis visceral. De los 85 pacientes considerados no aptos 29 (34,1%) fueron sometidos a cirugía convencional, 24 (28,3%) a radioterapia, 4 (4,7%) a inhibidores de la vía de Hedgehog (solo indicado para el CCB) y 2 (2,4%) a tratamiento paliativo. No hubo datos de seguimiento de 14 pacientes (16,5%). CONCLUSIÓN: Las comorbilidades médicas fueron la razón más habitual para retener la cirugía de Mohs. Retener un tratamiento en función de una propagación a lugares distantes no es algo habitual. La mayoría de los pacientes considerados no aptos recibieron tratamientos más sencillos: cirugía convencional o radioterapia, siendo los inhibidores de la vía de Hedgehog una opción novedosa

BACKGROUND: Regesmohs registry is a nationwide registry including patients evaluated for Mohs surgery in 17 Spanish centres since July 2013. Given that Mohs surgery is the therapy with best results for high risk basal cell carcinoma (BCC) and other skin tumours, we wanted to describe the reasons that lead to some patients being excluded from this therapy and the alternative treatments that they received. These data may be useful to avoid excluding patients for Mohs surgery use, to estimate the healthcare demand of these patients and the demand for Hedgehog inhibitors therapy in this group. OBJECTIVE: To describe patients excluded for Mohs surgery after pre-surgical assessment, and the treatments that they received. METHODS: Regesmohs includes all consecutive patients assessed for Mohs surgery in the participating centres, collecting data on patient characteristics, intervention, and short and long-term results. Patients excluded for Mohs surgery after pre-surgical evaluation were described. RESULTS: 3011 patients were included in Regesmohs from July 2013 to October 2016. In 85, Mohs surgery was not performed as they were considered inadequate candidates. 67 had BCC. Reasons for exclusion were: medical contraindication (27.1%, n = 23) low-risk tumour in (18.8%, n = 16) and giant tumour and bone invasion (15.3%, n = 13). Only 1 patient (1.2%) showed lymph node involvement and no patients had visceral metastases. Of the 85 excluded patients, 29 (34.1%) were treated with conventional surgery, 24 (28.3%) with radiotherapy, 4 (4.7%) with inhibitors of the Hedgehog pathway (only indicated for BCC), and 2 (2.4%) received palliative care. We had no follow-up data on 14 patients (16.5%). CONCLUSION: Medical comorbidities were the most common reason for withholding Mohs surgery. Withholding therapy on the basis of distant extension is uncommon. Most excluded patients received simpler therapies: conventional surgery or radiotherapy, with hedgehog inhibitors being a new option

Mohs micrographic surgery in the elderly: comparison of tumours, surgery and first-year follow-up in patients younger and older than 80 years old in REGESMOHS.

BACKGROUND: The elderly population is increasing and more patients in this group undergo Mohs micrographic surgery (MMS). The few publications investigating MMS in elderly people conclude that it is a safe procedure; however, these are single-centre studies without a comparison group. OBJECTIVE: To compare the characteristics of patients, tumours, MMS and 1-year follow-up in patients younger than 80 years, with patients older than 80 years at the time of surgery. METHODS: Data was analysed from REGESMOHS, a prospective cohort study of patients treated with MMS. The participating centres were 19 Spanish hospitals where at least one MMS is performed per week. Data on characteristics of the patient, tumour and surgery were recorded. Follow-up data were collected from two visits; the first within 1 month postsurgery and the second within the first year. RESULTS: From July 2013 to October 2016, 2575 patients that underwent MMS were included in the registry. Of them, 1942 (75.4%) were aged <80 years and 633 (24.6%) were ≥80 years old. In the elderly, the tumour size was significantly higher with a higher proportion of squamous cell carcinoma. Regarding surgery, elderly more commonly had tumours with deeper invasion and required a higher number of Mohs surgery stages, leaving larger defects and requiring more time in the operating room. Despite this, the incidence of postoperative complications was the same in both groups (7%) and there were no significant differences in proportion of relapses in the first-year follow-up. CONCLUSION: The risk of short-term complications and relapses were similar in elderly and younger groups. MMS is a safe procedure in the elderly.

Descripción de las intervenciones quirúrgicas recogidas en el registro español de cirugía de Mohs (REGESMOHS) (2013-2015) / Characterization of Surgical Procedures in the Spanish Mohs Surgery Registry (REGESMOHS) for 2013-2015

Introducción: El Registro Español de Cirugía de Mohs recoge los datos de aplicación y resultados de esta técnica en España. Se describen los datos de las intervenciones realizadas desde el inicio del Registro en julio de 2013 a enero de 2016. Se analizan los datos de las cirugías tanto perioperatorios como intraoperatorios. Material y métodos: Estudio de cohortes prospectivo en el que participan 18 centros. Se recogen los datos de las intervenciones quirúrgicas como tipo de anestesia, técnica quirúrgica, ingreso hospitalario, número de estadios, manejo de factores de riesgo preoperatorios, tratamientos complementarios, tratamientos previos, tipo de tumor, tiempo empleado en la cirugía y complicaciones. Resultados: Se analizan 1.796 intervenciones quirúrgicas. El tumor intervenido con más frecuencia es el carcinoma basocelular (85,96%), seguido del carcinoma epidermoide (6,18%), lentigo maligno (2,81%) y dermatofibrosarcoma protuberans (1,97%). El 66,9% de los tumores eran primarios, el 19,2% recurrentes y el 13,9% persistentes. El tratamiento previo más frecuente fue quirúrgico. La cirugía de Mohs se realizó con más frecuencia bajo anestesia local (86,7%) y de forma ambulatoria (71,8%). En el 89,5% de los casos se utilizó la técnica de Mohs en congelación. El número de etapas requerido para alcanzar márgenes libres de tumor fue una en 56,45% de los pacientes, 2 en 32,1%, 3 en 7,1%, 4 en 2,7% y 5 o más en 1,8%. El propio dermatólogo reconstruyó el defecto en el 98% de los pacientes y la técnica reconstructiva más utilizada fue el colgajo (47,2%). Solo el 1,62% de los pacientes presentó alguna complicación intraoperatoria y la mediana de la duración de la cirugía fue 75 (p25:60-p75:100). Conclusión: Las características de los pacientes y tumores tratados son similares a las descritas en estudios de las mismas características en otras áreas geográficas. Existe un porcentaje mayor de lentigo maligno y dermatofibrosarcoma protuberans. La reconstrucción la realiza el dermatólogo con más frecuencia que en otras series. El tiempo de utilización de quirófano no es mucho mayor que para otras técnicas y la tasa de complicaciones intraoperatorias es muy reducida (AU)

Introduction: The Spanish Mohs Surgery Registry is used to collect data on the use and outcomes of Mohs micrographic surgery (MMS) in Spain. The aim of this study was to describe perioperative and intraoperative data recorded for MMS procedures performed between July 2013 (when the registry started) and January 2016. Material and methods: Prospective cohort study of data from 18 hospitals. The data collected included type of anesthesia, surgical technique, hospital admission, number of Mohs stages, management of preoperative risk factors, additional treatments, previous treatments, type of tumor, operating time, and complications. Results: Data were available for 1796 operations. The most common tumor treated by MMS was basal cell carcinoma (85.96%), followed by squamous cell carcinoma (6.18%), lentigo maligna (2.81%), and dermatofibrosarcoma protuberans (1.97%). Primary tumors accounted for 66.9% of all tumors operated on; 19.2% of tumors were recurrent and 13.9% were persistent. The most common previous treatment was surgical. MMS was mostly performed under local anesthesia (86.7% of cases) and as an outpatient procedure (71.8%). The frozen section technique was used in 89.5% of cases. One stage was needed to achieve tumor-free margins in 56.45% of patients; 2 stages were required in 32.1% of patients, 3 in 7.1%%, 4 in 2.7%, and 5 or more in 1.8%. The defect was reconstructed by the dermatologist in 98% of patients and the most common technique was flap closure (47.2%). Intraoperative complications were recorded for just 1.62% of patients and the median (interquartile range) duration of surgery was 75 (60-100) minutes. Conclusion: The characteristics of the patients and tumors treated by MMS are similar to those reported for similar studies in other geographic areas. Lentigo maligna and dermatofibrosarcoma protuberans accounted for a higher proportion of cases in our series, and repair of the surgical defect by a dermatologist was also more common. Operating times in MMS are not much longer than those reported for other procedures and the rate of intraoperative complications is very low (AU)
