Topical Imiquimod in Treating Patients With Recurrent Paget's Disease of the Vulva
RATIONALE: Biological therapies, such as imiquimod, may stimulate the immune system in different ways and stop tumor cells from growing. Applying topical imiquimod to the vulva may be an effective treatment for recurrent Paget's disease.
PURPOSE: This clinical trial is studying how well topical imiquimod works in treating patients with recurrent Paget's disease of the vulva.
Procedure: therapeutic conventional surgery

This is a pilot study of the use of a topical immunomodulatory agent, imiquimod, for the treatment of recurrent Extramammary Paget's disease (EMPD).
The patient will be seen in clinic every six weeks during treatment for examination. Imiquimod cream is to be applied 3 times per week for 12 weeks.Procedure: biopsy
Punch biopsy and photography will be performed at the baseline and 12 week time points.Procedure: therapeutic conventional surgery
If the lesion is still present after 12 weeks of therapy, the treating physician will recommend excision of the lesion four weeks after completion of therapy (week 16).
- To assess the clinical and histologic effects of topical imiquimod therapy on recurrent extramammary Paget's disease.
OUTLINE: This is a pilot, prospective, multicenter study.
Patients apply topical imiquimod cream to a target vulvar lesion 3 times weekly. Treatment continues for up to 12 weeks in the absence of disease progression or unacceptable toxicity. If the lesion is still present after completion of 12 weeks of imiquimod therapy, the patient undergoes surgical excision of the target lesion (and any other progressive lesions suspicious for evolving adenocarcinoma) at week 16.
Patients undergo punch biopsy and photographic assessment of a target vulvar lesion at baseline and again at 12 weeks.
After completion of imiquimod therapy or after surgical excision, patients are followed at 6 weeks and then every 3 months for at least 2 years.
