Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy of low dose rate light fractionated aminolevulinic acid-Photodynamic Therapy (ALA-PDT) for treatment of usual type Vulvar Intraepithelial Neoplasia (uVIN) and lichen sclerosus (LS). ;Secondary Objective: To determine clearance of HPV after treatment of uVIN; to assess normalization immunocompetent cell counts and of expression of a number of markers (Ki67, p16, p53, mir-155) after treatment; to monitor pain during and after treatment; to monitor quality of life before and after treatment. ;Primary end point(s): Clinical response to the treatment in VIN or LS lesions after the end of ALA-PDT treatment measured by 1) reduction in lesion size after the end of treatment as visualized with high resolution photographs, 2) histological regression of uVIN or LS to ‘normal’ vulvar tissue as visualized in H/E stained sections and 3) relieve of symptoms like itching and disorder-related pain. ;Timepoint(s) of evaluation of this end point: Leeen s.v.p. invullen!

Secondary

MeasureTime frame
Secondary end point(s): Normalization of immunocompetent cells numbers in the region of the disorder at 4 weeks after the end of treatment; clearance of HPV DNA in uVIN lesions at 4 weeks after treatment; normalization of expression levels of Ki67, p16 and p53 at 4 weeks after treatment; normalization of expression level of mir-155 at at 4 weeks after treatment; improvement of quality of life at 4 weeks after treatment; and assessment of treatment-induced pain.;Timepoint(s) of evaluation of this end point: 4 weeks after treatment.
