Title: Phase IIA Trial of 1% Topical Cidofovir for Treatment of High-Grade Perianal Squamous Intraepithelial Lesions in HIV-Infected Men and Women
Brief Summary: RATIONALE: High-grade squamous intraepithelial lesions of the skin near the anus are caused by the human papillomavirus (HPV). Antiviral drugs,, such as cidofovir, act against viruses and may stop these lesions from becoming cancer.

PURPOSE: This phase II trial is studying the side effects and how well topical cidofovir works in treating HIV-infected patients with high-grade squamous intraepithelial lesions of the skin near the anus.

C: DISEASE CHARACTERISTICS:

* Histologically confirmed perianal high-grade squamous intraepithelial lesions (HSIL) within the past 12 weeks

  * The perianal skin (i.e., perianus) is defined as extending radially 5 cm from the anal verge
  * Lesions must cover a surface area of ≥ 3 square centimeters
  * Lesions extending outside the perianus (e.g., vulvar lesions on the posterior perineum bordering the perianus) are allowed
* Serologic documentation of HIV infection AND meets 1 of the following criteria:

  * Has been on stable highly active anti-retroviral therapy (HAART) for ≥ 12 weeks prior to study entry
  * Has a CD4 count of \> 200/mm³ AND is not receiving anti-retroviral therapy OR is currently receiving a non-HAART\* anti-retroviral regimen with no plans to initiate HAART within the next 12 weeks NOTE: \* A non-HAART regimen is considered to be a therapy that does not include a protease inhibitor or a non-nucleoside reverse transcriptase inhibitor
* No untreated invasive cancer of the lower genital tract
* No concurrent neoplasia requiring cytotoxic therapy

PATIENT CHARACTERISTICS:

* Karnofsky performance status 70-100%
* Life expectancy ≥ 3 months
* Hemoglobin ≥ 8 g/dL
* ANC ≥ 1,000/mm³
* Platelet count ≥ 75,000/mm³
* Creatinine \< 1.5 times upper limit of normal (ULN)
* Total or conjugated (direct) bilirubin ≤ 2.5 times ULN

PRIOR CONCURRENT THERAPY:

* See Disease Characteristics
* Recovered from prior ablative or surgical treatment of perianal dysplasia
* At least 4 weeks since prior topical treatment for perianal dysplasia

  * If any prior treatment caused significant trauma to ther area, healing should occur prior to starting treatment
* More than 14 days since prior acute treatment for infection (other than for oral thrush, yeast vaginitis, or genital herpes) or other serious medical illness
* No concurrent corticosteroids other than replacement doses
* No other concurrent investigational drugs except IND-approved anti-retroviral agents
* No concurrent systemic cytotoxic chemotherapy
D: Inclusion Criteria:

* Patients who present with vulvar or vaginal dysplasias or condylomas that require surgical intervention will be informed of the study by the treating physician
* Pre-operative biopsies to confirm presence of dysplasia / condyloma. Patients with dysplasias of grade 3 / CIS will be included at the discretion of the treating surgeon and will have had invasion confidently excluded by clinical exam and biopsy.

Exclusion Criteria:

* Patients under the age of eighteen or who are pregnant will be excluded
