Filter by: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.
This phase I trial studies the side effects and best dose of erlotinib hydrochloride in preventing cancer in patients with precancerous lesions of the lung. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
RATIONALE: Rosuvastatin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving rosuvastatin after surgery may kill any tumor cells that remain after surgery. It may also keep polyps from forming or colon cancer from coming back. It is not yet known whether rosuvastatin is more effective than a placebo in treating colon cancer that was removed by surgery. PURPOSE: This randomized phase III trial is studying rosuvastatin to see how well it works compared with placebo in treating patients with stage I or stage II colon cancer that was removed by surgery.
RATIONALE: Screening tests may help doctors find cancer cells early and plan better treatment. It is not yet known whether endoscopy every 2 years is more effective than endoscopy only as needed in finding esophageal cancer in patients with Barrett esophagus. PURPOSE: This randomized phase III trial is studying endoscopy every 2 years to see how well it works compared with endoscopy only as needed in monitoring patients with Barrett esophagus.
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: Green tea extract contains ingredients that may prevent or slow the growth of monoclonal gammopathy of undetermined significance and/or smoldering multiple myeloma. PURPOSE: This phase II trial is studying how well green tea extract works in treating patients with monoclonal gammopathy of undetermined significance and/or smoldering multiple myeloma.
