Filter by:RATIONALE: Vaccines made from a gene-modified virus may help the body build an effective immune response to prevent viral infection. PURPOSE: This phase II trial is studying how well vaccine therapy works in preventing human papillomavirus (HPV) infection in young HIV-positive male patients who have sex with males.
RATIONALE: Infrared coagulator ablation may be effective in preventing the development of anal cancer in patients with anal neoplasia PURPOSE: This randomized phase III trial is studying infrared coagulator ablation to see how well it works compared to observation in preventing anal cancer in HIV-positive patients with anal neoplasia.
The purpose of this study is to test the preventive effects of a combination of drugs: polyphenon E (PPE) derived from green tea extracts, and erlotinib. Because this combination of drugs has not been tested in humans before for the prevention of cancer, it is not clear which dose of each agent will be optimal in combination. We will test the safety of the combination of PPE and erlotinib and see what effects (good and/or bad) it has on the patient's premalignant lesion, and find the highest dose of each agent that can be given in combination without causing severe side effects.
Precancerous lesions of the cervix occur frequently and are treatable. This justifies a population-based screening program. Following an abnormal Pap smear, patients are referred for a colposcopic exam to confirm the presence/stage of disease and select appropriate treatments. Unfortunately, these approaches do not detect all lesions or can sometimes give 'false positive' results (resulting in overtreatment). We are testing a device called a 'multispectral digital colposcope' to determine whether it is more effective at detecting precancerous cervical lesions than existing tools. Success in our study will make diagnoses more accurate and reduce the costs associated with unnecessary treatments.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiation therapy uses high energy x-rays to kill tumor cells. Giving paclitaxel, cisplatin, and cetuximab together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying paclitaxel, cisplatin, and cetuximab to see how well they work when followed by cetuximab and two different doses of intensity-modulated radiation therapy in treating patients with HPV-associated stage III or stage IV cancer of the oropharynx that can be removed by surgery.
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. PURPOSE: This randomized phase I trial is studying the side effects and best dose of photodynamic therapy in treating patients with premalignant or early stage head and neck tumors.
RATIONALE: Women who do not undergo routine cervical screening may be more likely to collect a self-sample for human papillomavirus testing. PURPOSE: This randomized clinical trial is studying self-sampling in women who do not undergo routine cervical screening.
RATIONALE: Doctors use a swab to collect cell samples when testing for anal cancer and human papillomavirus. It is not yet known which type of swab is more effective in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men. PURPOSE: This clinical trial is comparing two types of swabs in collecting cell samples for anal Pap tests and human papillomavirus tests in men who have sex with men.
The goal of this clinical research study is to learn how Actos (pioglitazone) may affect oral premalignant lesions (OPLs) and/or the risk of mouth cancer. The safety of this drug will also be studied.
RATIONALE: Gathering information about human papilloma virus (HPV) infection in HIV-positive men who have sex with men may help doctors learn more about the disease. PURPOSE: This clinical trial is studying HPV infection in HIV-positive Indian men who have sex with men.
