IntroduccióN:
El carcinoma basocelular (CBC) es la neoplasia cutánea maligna más común.
Objetivo:
se investigó el riesgo de recurrencia y de nueva neoplasia cutánea maligna después del tratamiento de CBC.
MéTodo:
Estudio retrospectivo. Fueron identificados los pacientes con diagnóstico histopatológico de CBC primario, de enero de 2007 a diciembre de 2009, y se revisaron los expedientes para investigar el número de recurrencias, la localización, el tipo de tratamiento y la variante histopatológica, determinando nuevas neoplasias cutáneas malignas. El análisis incluyó estadística descriptiva e inferencial, considerando significativa una p < 0.05.
Resultados:
Se incluyeron 397 pacientes, con un seguimiento promedio de 4 ± 1.5 años. La recurrencia se presentó en el 4% y se relacionó con un mayor tiempo de evolución (36 vs. 32 meses; p = 0.04) y haber sido tratado mediante técnicas destructivas (electrofulguración, criocirugía o imiquimod; 31 vs. 4%; p = 0.0004). No hubo relación con la localización ni con la variante histopatológica. El riesgo de desarrollar una nueva neoplasia maligna fue del 25%, y de ellas el 66% correspondió a un nuevo CBC y el 30% a carcinoma espinocelular.
Conclusiones:
Es importante el seguimiento de los pacientes con CBC para identificar tanto las recurrencias como las nuevas neoplasias malignas, independientemente de la localización y de la variante histopatológica del primario. El tratamiento con técnicas quirúrgicas condiciona una menor recaída que las técnicas destructivas.
Introduction:
Basal cell carcinoma (BCC) is the most common skin malignant neoplasm.
Objective.:
Investigate the risk of recurrence and of new skin malignant neoplasms, after treatment of BCC.
Method:
Retrospective study. We examined the files of patients with histopathological diagnosis of primary BCC, between January 2007 and December 2009, and we investigate number of recurrences and their relationship with localization, treatment type, and histopathological variant, and the number of new skin malignant neoplasms. For analysis, we employed descriptive and inferential statistics; p < 0.05 was considered significant.
Results:
A total of 397 patients, with an average follow-up of 4 ± 1.5 years. Recurrences presented in 4%. Recurrences were related with longer time of evolution (36 vs. 32 months; p = 0.04) and treatment with destructive techniques (electrofulguration, cryosurgery or imiquimod; 31 vs. 4%; p < 0.001). There was no relationship with localization, or the histopathological variant. The risk of developing a new malignant neoplasm was 25%; 66% corresponded to a new BCC and 30% to squamous cell carcinoma.
Conclusions:
Follow-up of patients with BCC should be conducted independently of their localization and histopathological variant, especially in patients with greater evolution time, principally with surgical techniques.
