The purpose of this study is a prospective,double-blinded, randomized trial to compare the rate of healing following PRK after the use of two commercially available 4th generation fluoroquinolones, moxifloxacin and gatifloxacin.
RATIONALE: Chemoprevention is the use of certain drugs or substances to keep cancer from forming, growing, or coming back. The use of lycopene, a substance found in tomatoes, may keep prostate cancer from forming in patients at high risk of developing prostate cancer. PURPOSE: This phase I trial is studying the side effects and best dose of lycopene in preventing prostate cancer in patients who are at high risk of developing prostate cancer.
RATIONALE: Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. Eating a diet high in lycopene, a substance found in tomatoes and tomato products, may keep cancer from forming or growing. Collecting and storing samples of blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer. PURPOSE: This randomized clinical trial is studying how well lycopene works in treating patients with prostate cancer or benign prostatic hyperplasia.
RATIONALE: Medroxyprogesterone may help shrink or slow the growth of kidney cancer. Interferon may interfere with the growth of tumor cells. Aldesleukin may stimulate white blood cells to kill tumor cells. It is not yet known whether giving medroxyprogesterone, interferon, or aldesleukin alone is more effective than giving interferon together with aldesleukin in treating kidney cancer. PURPOSE: This randomized phase III trial is studying medroxyprogesterone, interferon, or aldesleukin to see how well they work when given alone compared to interferon combined with aldesleukin in treating patients with metastatic kidney cancer.
RATIONALE: An educational program may improve coping and quality of life in younger women who have recently been treated for early-stage breast cancer. PURPOSE: This randomized clinical trial is studying how well an educational program works in helping younger women cope with the recent diagnosis of and treatment for stage I or stage II breast cancer.
RATIONALE: Meeting together with other breast cancer patients to receive psychosocial support and to learn to reduce stress may help patients cope with their diagnosis, have a better quality of life, and live more comfortably. PURPOSE: This randomized clinical trial is studying how well psychosocial support works in treating women with recurrent breast cancer or stage I, stage II, or stage IV breast cancer.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these treatments after surgery may kill any tumor cells that remain. PURPOSE: This randomized phase III trial is studying radiation therapy together with combination chemotherapy to see how well they work with or without surgery in treating patients with locally advanced esophageal cancer that can be removed by surgery.
RATIONALE: Biological therapies, such as interleukin-2 and interferon, may stimulate the immune system in different ways and stop tumor cells from growing. It is not yet known whether interleukin-2 given by infusion is more effective than interleukin-2 given by injection when combined with interferon in treating metastatic kidney cancer. PURPOSE: This randomized phase III trial is studying interleukin-2 given by infusion to see how well it works compared to interleukin-2 given by injection when combined with interferon in treating patients with metastatic kidney cancer.
RATIONALE: An educational program may be effective in increasing monthly skin self-examinations to detect melanoma in healthy participants. PURPOSE: This randomized clinical trial is studying how well an educational program works in increasing monthly skin self-examinations to detect melanoma in healthy participants.
