Cáncer cutáneo distinto de melanoma: tendencia de la incidencia poblacional en Girona, 1994-2007 / Non-melanoma skin cancer: incidence time trends analysis in Girona, Spain, 1994-2007

Fundamento y objetivo: Describir la tendencia de la incidencia del cáncer cutáneo no melanoma (CCNM): carcinoma escamoso cutáneo (CEC) y carcinoma basocelular (CB) en Girona.Pacientes y método: Los casos incluidos en el estudio fueron los 9.247 pacientes con diagnóstico de CCNM reportados en el Registro de Cáncer Poblacional de Girona durante el período comprendido entre enero de 1994 y diciembre de 2007. Para el análisis de la tendencia de la incidencia poblacional se utilizó la tasa ajustada a la población mundial y se estandarizó por el método directo; para la tendencia por grupo de edad se utilizó la tasa específica por estos grupos (45-64, > 64 años). Se excluyó el grupo de menores de 45 años. Se utilizaron los métodos de regresión joinpoint para estimar las tendencias temporales mediante el cálculo del porcentaje del cambio anual según el grupo histológico y los grupos de edad seleccionados. Resultados: La tasa ajustada a la población mundial fue de 55,74 casos por 105 personas-año, siendo superior en varones (67,13) que en mujeres (46,9); la del CB fue superior a la del CEC (44,56 y 11,18 respectivamente). La tasa del CCNM en ambos sexos se incrementó desde 48,53 (1994-95) hasta 60,54 (2006-07) con un porcentaje de cambio anual del 2,30%, siendo más importante este incremento para la mujer (2,65%) que para el varón (1,99%). Conclusiones: En nuestra población se detecta un importante incremento en la incidencia del CCNM, siendo más importante para el CEC que para el CB, en los mayores de 64 años y en las mujeres (AU)

Background and objective: We aimed to assess the population-based incidence trends of non-melanoma skin cancer (NMSC): squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). Patients and method: From January 1994 to December 2007, 9,247 patients diagnosed with NMSC were recruited in the population-based Cancer Registry of Girona. Incidence rates were calculated with age-adjusted according to the Word standard population (WASR) by a direct method and reported as number of new cases per 100,000 person-year. To evaluate incidence trends by age group we used specific rates for these groups (45-64, > 64 years). We excluded patients younger than 45 years. Joinpoint method was used to estimate the average annual percentage change (AAPC) for the whole study period according to histologic and age groups. Results: Age-adjusted incidence was 55.74 per 105 person-year; it was higher in males (67.13) than in females (46.9). Age-adjusted incidence for BCC was higher compared with the incidence for SCC (44.56 and 11.18 respectively). Age-adjusted incidence rate for NMSC for both sexes increased from 48.53 (1994-95) to 60.54 (2004-05) with an AAPC of 2.30%, which was higher in females (2.65%) than in males (1.99%). Conclusions: There has been a significant increase in the incidence of NMSC in our area, particularly evident for SCC, and it is more important in patients older than 64 years and in females (AU)

RESULTS: Age-adjusted incidence was 55.74 per 10(5) person-year; it was higher in males (67.13) than in females (46.9). Age-adjusted incidence for BCC was higher compared with the incidence for SCC (44.56 and 11.18 respectively). Age-adjusted incidence rate for NMSC for both sexes increased from 48.53 (1994-95) to 60.54 (2004-05) with an AAPC of 2.30%, which was higher in females (2.65%) than in males (1.99%).
