Arms Assigned Interventions
Experimental: Primary Imiquimod
Treatment with imiquimod will be patient self-administered for a period of 4 months with possible extension to 6 months. A thin layer of imiquimod cream should be applied to the lesion and remain overnight without a cover. Application will be once a week for 2 weeks, then twice a week the following 2 weeks and, if tolerated, 3 times a week for the last weeks. In case of severe side-effects the number of applications can be reduced; a treatment-free period of no more than 1 week is permitted
Drug: Imiquimod
Other Names:
  • Aldara
Procedure: Surgery
Other Names:
  • Excision
  • Ablation
Active Comparator: Primary surgery
The type of surgery (excision or ablation) will be based on clinical findings and surgeon's judgement. After excision the specimen will be histologically analyzed to assess resection margins and rule out invasion.
Procedure: Surgery
Other Names:
  • Excision
  • Ablation
Open or close this module Outcome Measures
Primary Outcome Measures:
1. Complete clinical response
[ Time Frame: 6 months ]

No clinical evidence of vulvar lesion, i.e. 100% reduction of primary lesion size
Secondary Outcome Measures:
1. Clinical response/ lesion size
[ Time Frame: 6 months ]

Vulvar lesions will be described, measured with calipers, mapped and photographed. The digital photos will be analyzed with a computer program (ImageJ) to calculate the total lesion size in cm². Results will be classified as: no response (NR, reduction in lesion size of 25% or less), weak partial response (wPR, 26-75% reduction), strong partial response (stPR, 76%-99% reduction) and Complete response (CR, 100% reduction).
2. Histologic response
[ Time Frame: 6 months ]

At baseline punch biopsies will be taken from the affected areas. The site of the initial biopsy will be photodocumented to ensure that the follow-up biopsy at 6 months is taken from the same site. Histologic results will be classified as response (R): complete disappearance of usual type VIN or reduction to VIN1,or no response (NR). All biopsy samples will be analysed independently by two experienced gynecologic pathologists unaware of the treatment allocation
3. Extent of surgery
[ Time Frame: 6 months ]

The number, types and extent of surgical procedures will be recorded. The extent of surgery will be recorded as total operated lesion size (in cm², as measured on pre-operative photograph) and relative operated lesion size (percentage of operated lesion size compared with the original pretreatment lesion size)
4. HPV status
[ Time Frame: 6 months ]

HPV status will be measured with the qualitative cobas® HPV Test, Roche, and the the APTIMA ® HPV assay, Gen-Probe.
5. Clinical response/lesion size
[ Time Frame: 12 months ]

Vulvar lesions will be described, measured with calipers, mapped and photographed. The digital photos will be analyzed with a computer program (ImageJ) to calculate the total lesion size in cm². Results will be classified as: no response (NR, reduction in lesion size of 25% or less), weak partial response (wPR, 26-75% reduction), strong partial response (stPR, 76%-99% reduction) and Complete response (CR, 100% reduction).
6. Extent of surgery
[ Time Frame: 12 months ]

The number, types and extent of surgical procedures will be recorded. The extent of surgery will be recorded as total operated lesion size (in cm², as measured on pre-operative photograph) and relative operated lesion size (percentage of operated lesion size compared with the original pretreatment lesion size)
7. HPV status
[ Time Frame: 12 months ]

HPV status will be measured with the qualitative cobas® HPV Test, Roche, and the the APTIMA ® HPV assay, Gen-Probe.
Other Outcome Measures:
1. "Cervical Dysplasia Distress" Questionnaire
[ Time Frame: 6 months ]

Change from baseline in "Cervical Dysplasia Distress" score at 6 months
2. "Cervical Dysplasia Distress" questionnaire
[ Time Frame: 12 months ]

Change from Baseline in "Cervical Dysplasia Distress" score at 12 months
3. "Fear of Progression" Questionnaire
[ Time Frame: 6 months ]

Change from Baseline "Fear of Progression" score at 6 months.
4. "Fear of Progression" questionnaire
[ Time Frame: 12 months ]

Change from Baseline "Fear of Progression" score at 12 months.
5. "Sexual activity" Questionnaire
[ Time Frame: 6 months ]

Change from baseline "Sexual activity" score at 6 months
6. "Sexual activity" questionnaire
[ Time Frame: 12 months ]

Change from baseline "Sexual activity" score at 12 months
7. Immune cells in the epidermis
[ Time Frame: 6 months ]

Histochemical analysis of immune cells from vulvar biopsy samples will be performed at baseline and at 6 months. Frozen sections will be prepared and stained with corresponding cell markers. Immune cell populations will be quantified as number of cells per square millimetre and will be compared between the two treatment groups. The following markers and their primary antibodies will be analysed: CD1a, marker for Langerhans cells, CD94, marker for natural killer cells, CD4, marker for T-helper cells, CD8, marker for cytotoxic T-cells and CD207, marker for immature dendritic cells expressing Langerin.
8. Aesthetic results
[ Time Frame: 6 months ]

Detailed photos of the overall vulva will be taken. Photos will be compared to photos taken at baseline and judged by 4 independent, blinded observers for aesthetic results.
9. Aesthetic results
[ Time Frame: 12 months ]

Detailed photos of the overall vulva will be taken. Photos will be compared to photos at baseline and judged by 4 independent, blinded observers for aesthetic results.
10. Visual analogue scale (VAS) for assessment of pain and pruritus
[ Time Frame: 6 months ]

Change of VAS score for pain and pruritus from baseline to 6 months. VAS will be assessed at baseline, 1,2 ,3,4,5 and 6 months.
