Abstract
Antecedentes: la incidencia del cáncer no melanoma de piel (CNMP), principalmente en países tropicales ha aumentado en grandes proporciones. La identificación de lesiones sospechosas y aquellas relacionadas directamente con el cáncer de piel es efectuada en ocasiones por colegas de muchas especialidades médicas. Objetivos: estudiar las características de la frecuencia del CNMP en relación con ciertos factores de riesgo en el Hospital José María Cullen, de la ciudad de Santa Fe, capital de la provincia del mismo nombre, Argentina. Materiales y métodos: estudio retrospectivo, no experimental, descriptivo y de corte transversal. La muestra quedó conformada por 61 pacientes de ambos sexos y de 1 a 83 años. Se confeccionó una historia clínica completa de los pacientes candidatos a la toma de biopsia, que luego fue analizada por el Servicio de Anatomía Patológica. Se realizó un análisis descriptivo utilizando el programa SPSS 11.5, mediante el cual se usó la prueba de Chi cuadrado y tablas de contingencia para relacionar las variables y comparar los datos. Se estableció una asociación estadísticamente significativa cuando se halló un valor de pBackground: The incidence of non-melanoma skin cancer (NMSC), mainly in tropical countries has increased in large proportions. The identification of suspicious lesions and those directly related to the skin cancer is made by colleagues of many medical specialities. Objectives: Study the characteristics of the frequency of NMSC and their relation with certain risk factors in the Hospital José María Cullen, city of Santa Fe, capital of the province of the same name, Argentina. Materials and Methods: This was a retrospective, not experimental, descriptive and transversal cut study. The sample was composed by 61 patients of both sexs and from 1 to 83 years old. A complete clinical history of patients with suspected lesions were developed. After the biopsy collection, the Department of Pathology analyze them. A descriptive analysis was performed using SPSS 11.5 program; Chi-square test and contingency tables were used to relate variables and compare data. It stablished a statistically significant association when it founded a value of p<0,05. Results: We observed that the frequency of NMSC was 29.5%, affecting mostly male (72.2%). Statistically significant difference were found (p=0,008), with respect to the female gender. Patients between 61 and 70 years were the most afected age group with a frequency of 38.9% (p=0,001).The most common type of NMSC was basal cell carcinoma (77.8%) and the most frequent location was head and neck (61.1%). The risk factor found most frequently (94.4%) was the photoexposure (p=0,00) and the skin phototype most affected was the type II (61.1%). Conclusion: The incidence of non-melanoma skin cancer is high.
