An ultrasound analysis of the response of Gorlin syndrome-related and sporadic basal cell carcinomas to aminolaevulinic acid photodynamic therapy

The average response to ALA PDT of Gorlin syndrome-related BCC closely resembles that for the sporadic population, with the same wide range of responses for a given dose. Ultrasound parameters measured at treatment and at 4-6 weeks post-treatment aid prediction of outcome and necessity for further treatment.
