Evaluación de la tasa de detección incidental de cáncer cutáneo: estudio prospectivo en un servicio hospitalario / Incidental Skin Cancer Detection in a Hospital Department: A Prospective Study

ANTECEDENTES Y OBJETIVO: El cáncer de piel es un motivo frecuente de derivación a dermatología, pero también puede ser un hallazgo incidental durante la exploración por otro motivo de consulta. El objetivo del estudio fue comparar las características de las lesiones diagnosticadas de un cáncer cutáneo de forma incidental y compararlas con aquellas que constituían el motivo de derivación con pacientes diagnosticados de cáncer de piel (carcinoma espinocelular, carcinoma basocelular y melanoma) durante un año en una consulta de dermatología. Se recogieron diferentes variables y se realizó el análisis estadístico mediante la prueba de la Ji cuadrado de Pearson comparando el grupo en el que el diagnóstico era el motivo de derivación frente al grupo en el que el diagnóstico fue hallazgo incidental. RESULTADOS: Se recogieron datos de 433 pacientes, con una mediana de edad de 72 años, con 233 (51,3%) pacientes del sexo femenino y un predominio de fototipos II y III. El carcinoma basocelular fue en todos los análisis la neoplasia más frecuente, representando un 68,4% (296/433). Un 26% de los tumores cutáneos malignos diagnosticados no estaban relacionados con el motivo de derivación. El análisis estadístico demostró que las diagnosticadas de forma incidental estaban localizadas en zonas no visibles, tenían un menor tamaño y menor tiempo de evolución. CONCLUSIONES: La alta tasa de cáncer de piel diagnosticado de forma incidental por el dermatólogo resalta la necesidad de realizar exploraciones exhaustivas a nuestros pacientes para facilitar la detección temprana y el tratamiento precoz

BACKGROUND AND OBJECTIVES: Skin cancer is a common cause for referral to dermatology, but it may also be an incidental finding during examination of patients referred for other reasons. The objective of the study was to compare the characteristics of skin cancer lesions (squamous skin carcinoma, basal cell carcinoma, melanoma) diagnosed at a dermatology department over 1 year between patients referred for suspected skin cancer and those referred for another reason but in whom skin cancer was detected as an incidental finding. Pearson's chi2 test was used to compare different study variables between the 2 groups. RESULTS: Data were collected from 433 patients with a mean age of 72 years; 233 (51.3%) of the patients were female. The most common skin types were Fitzpatrick types II and III. Basal cell carcinoma was the most frequent cancer in all the analyses and accounted for 68.4% of all cancers diagnosed (296/433). Twenty-six percent of the malignant skin tumors were detected incidentally. Statistical analysis revealed that these tumors tended to be located in nonvisible areas and were smaller and of more recent onset than tumors initially suspected to be malignant. CONCLUSIONS: The high rate of skin cancer diagnosed incidentally by dermatologists highlights the need to carry out thorough examinations of patients in order to facilitate early detection and treatment
