Squamous Intraepithelial Lesion clinical trials at UCSF

• Imiquimod, Fluorouracil, or Observation in Treating HIV-Positive Patients With High-Grade Anal Squamous Skin Lesions

  open to eligible people ages 25 years and up

  This randomized phase III trial studies imiquimod or fluorouracil to see how well they work compared to observation in treating patients with high-grade anal squamous skin lesions who are human immunodeficiency virus (HIV)-positive. Biological therapies, such as imiquimod, may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether imiquimod or fluorouracil is more effective than observation in treating high-grade anal squamous skin lesions.

• Topical or Ablative Treatment in Preventing Anal Cancer in Patients With HIV and Anal High-Grade Squamous Intraepithelial Lesions

  open to eligible people ages 35 years and up

  This randomized phase III trial compares topical or ablative treatment with active monitoring in preventing anal cancer in patients with human immunodeficiency virus (HIV) and high-grade squamous intraepithelial lesions (HSIL). Anal HSIL is tissue in the anal canal that has been damaged by infection with human papillomavirus (HPV) and is at risk for turning into anal cancer. It is not yet known if treating HSIL is more effective than active monitoring in preventing patients from developing anal cancer.
