Interventions |
Arm 1: low‐dose light fractionated 5‐aminolevulinic acid (gel) and photodynamic therapy (ALA‐PDT) Arm 2: imiquimod (5% cream) |
Outcomes |
Primary: clinical response to the treatment in VIN or LS lesions after the end of ALA‐PDT treatment measured by:
reduction in lesion size after the end of treatment as visualised with high resolution photographs;
histological regression of uVIN or LS to 'normal' vulval tissue as visualised in H/E stained sections;
relief of symptoms like itching and disorder‐related pain.
Secondary (assessed at 4 weeks post‐treatment):
normalisation of immunocompetent cell numbers in the region of the disorder;
clearance of HPV DNA in uVIN lesions;
normalisation of expression levels of Ki67, p16 and p53;
normalisation of expression level of mir‐155;
QoL;
pain related to treatment.
