Abstract
Actinic keratosis is currently considered not to be a precursor of squamous cell carcinoma but, rather, an initial stage of the disease. Furthermore, the incidence of both squamous cell carcinoma and basal cell carcinoma continues to increase. Topical drugs are now becoming widely used in the therapeutic management of nonmelanoma skin cancer and its precursor lesions. Here, we review the various topical drugs that are currently available and discuss their advantages and drawbacks. Therapeutic options include retinoids, 5-fluoracil, diclofenac, imiquimod, and photodynamic therapy.
Key words:
actinic keratosis
nonmelanoma skin cancer
topical treatment
Resumen
Actualmente se considera que la queratosis actínica no es un precursor del carcinoma de células escamosas, sino un estadio inicial del mismo, y la incidencia tanto del carcinoma escamocelular como del basocelular está en continuo aumento. Dentro del manejo terapéutico del cáncer cutáneo no melanoma, así como de las lesiones precursoras, se está imponiendo el uso de agentes farmacológicos tópicos. En el siguiente artículo se revisan las diversas alternativas farmacológicas tópicas de las que se dispone actualmente y se discuten sus ventajas y limitaciones. Entre estas alternativas se encuentran los retinoides, el 5-fluoracilo, el diclofenaco, el imiquimod y la terapia fotodinámica.
Palabras clave:
