Topical Imiquimod in Treating Patients With Recurrent Paget's Disease of the Vulva

Memorial Sloan Kettering Cancer Center8 enrolled

Overview

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.

OBJECTIVES: * 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.

Punch biopsy and photography will be performed at the baseline and 12 week time points.

therapeutic conventional surgeryPROCEDURE

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).

Percentage of Participants With Clinical and Histologic Remission

Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR

Time frame: 12 weeks post treatment
