ABSTRACT
Antecedentes y objetivo El tratamiento de elección inicial del carcinoma basocelular (CBC) es la escisión quirúrgica. Esta debería ser completa para reducir el riesgo de recidiva. Nuestro objetivo es conocer las características de los CBC en nuestra área de salud, el porcentaje de márgenes afectos, y los factores de riesgo para una resección quirúrgica incompleta. Material y métodos Estudio observacional retrospectivo de los CBC intervenidos en el Área de Salud del Hospital Universitario Nuestra Señora de Candelaria entre el 1 de enero de 2014 y el 31 de diciembre de 2014. Recogemos datos demográficos, clínicos e histológicos, servicio responsable, abordaje quirúrgico y estado de los márgenes. Resultados Se diagnosticaron 966 CBC correspondientes a 776 pacientes, siendo el 9% biopsias, el 89% escisiones y el 2% rebanados. La mediana de edad fue de 71 años y el 52% eran hombres. La localización más frecuente fue la cara (59,1%). Se analizaron los márgenes quirúrgicos en 506 CBC. El 17% presentó afectación de márgenes. El porcentaje de márgenes afectos fue significativamente mayor en los tumores de la cara (22% cara vs. 10% otra localización) y en los de subtipo histológico de alto riesgo (OMS) (25% subtipo de alto riesgo vs. 15% bajo riesgo). Conclusiones Las características de nuestros pacientes con CBC se asemejan a las descritas previamente. La localización facial y el subtipo histológico son factores de riesgo para la resección incompleta del CBC. Por lo tanto, el abordaje quirúrgico inicial de los CBC con estas características ha de planearse de forma cuidadosa (AU)
Background and objective Surgical excision is the treatment of choice for basal cell carcinoma (BCC). Complete excision with clear margins is important for reducing the risk of recurrence. The aims of this study were to describe the characteristics of BCCs in our health care area, calculate the percentage of positive margins after surgical excision, and determine the risk factors for incomplete excision. Material and methods Retrospective observational study of BCCs that were surgically removed at Hospital Universitario Nuestra Señora de Candelaria, in Santa Cruz de Tenerife, Spain, between January 1, 2014 and December 31, 2014. Information was collected on demographic, clinical, and histologic variables, surgical approach, margin status, and the department responsible. Results In total, 966 BCCs were diagnosed in 776 patients. Nine percent of tumors with complete data were biopsied, 89% were surgically excised, and 2% were removed by shave excision. The median age of patients with excised tumors was 71 years and 52% were men. BCCs were most often located on the face (59.1%). Surgical margins were analyzed in 506 cases, 17% of which had positive margins. Incomplete excision was significantly more common in tumors located on the face (22% vs. 10% for other locations) and in high-risk subtypes according to the World Health Organization classification (25% vs. 15% for low-risk subtypes). Conclusions The characteristics of BCCs in our health care area are similar to those described elsewhere. Facial location and histologic subtype are risk factors for incomplete excision. Careful surgical planning is therefore important in the initial management of BCCs with these characteristics (AU)

Sonidegib is a Hedgehog signalling pathway inhibitor approved for use in patients with advanced basal cell carcinoma (BCC) not eligible for surgery or radiotherapy. This report describes clinical experience with sonidegib in two patients with locally advanced BCC (one with a tumour adjacent to the right eye and the other with a tumour associated with the left ear) and in one patient with Gorlin syndrome. Two of the patients had recurrent and intractable tumours. Treatment with sonidegib 200 mg/day led to remission in both patients with locally advanced BCC within 7 months and to a reduction in the size and number of lesions after 4 months in the patient with Gorlin syndrome. Adverse effects reported in these patients were cramps, alopecia, ageusia and weight loss, all of which were mild and consistent with the known toxicity profile for sonidegib. Sonidegib has an important role to play in the effective treatment of challenging cases of advanced BCC. In parallel, a need remains to improve management protocols for patients with advanced BCC, particularly through earlier intervention and a multidisciplinary team approach.

BACKGROUND: Despite suffering high ultraviolet radiation levels, few data on malignant melanoma (MM) in Macaronesia are available. METHODS: Observational study of cutaneous MM cases diagnosed during a period of 12 years at a tertiary hospital in Canary Islands. RESULTS: A total of 532 patients (female/male = 1.4) with an average age of 56 years were included; 5% developed more than one MM, and 7% reported family history of MM. Phototype II (43%), dark eyes (41%), and dark hair (41%) predominated. There was a lower frequency of light-colored hair and eyes in those born in the Canary Islands. The most frequent locations of MM were on the back for men (37%) and on the lower extremities for women (35%). Among the infiltrating tumors (83%), the (median) thickness was 1.07 mm (women, 0.90 mm; men, 1.21 mm). Anatomopathological ulceration (AU) and a mitotic rate ≥1 mitosis/mm2 (HMR) were recorded in 27% of patients. Patients with regional disease constituted 12% of the population. The most common stage was IA (34%). Melanoma-specific survival (MSSV) decreased significantly with thickness, presence of AU, HMR, and sentinel lymph node disease. These four variables were independent prognostic factors. The five-year MSSV varied between 100% (stage IA) and 39% (stage IIIC). CONCLUSIONS: The characteristics of the patients were similar to those published in datasets from continental Europe, although the pigmentary features were darker in those originating from Macaronesia. The prognostic parameters described in the 7th edition of the American Joint Committee on Cancer (AJCC) independently predict MSSV in our patients.
