Filter by:RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of esomeprazole and aspirin may prevent esophageal cancer in patients with Barrett's metaplasia. It is not yet known whether esomeprazole is more effective with or without aspirin in preventing esophageal cancer in patients with Barrett's metaplasia. PURPOSE: This randomized phase III trial is studying esomeprazole with or without aspirin to compare how well they work in preventing esophageal cancer in patients with Barrett's metaplasia.
This randomized phase II trial is studying atorvastatin calcium to see how well it works compared to oligofructose-enriched inulin, sulindac, or a placebo in preventing cancer in patients at increased risk of developing colorectal neoplasia. Chemoprevention is the use of certain drugs or substances to keep cancer from forming, growing, or coming back. The use of atorvastatin calcium, oligofructose-enriched inulin, or sulindac may stop cancer from forming in patients at increased risk of colorectal neoplasia. It is not yet known whether atorvastatin calcium, oligofructose-enriched inulin, or sulindac are more effective than a placebo in preventing cancer in patients at increased risk of developing colorectal neoplasia.
RATIONALE: Photodynamic therapy uses a drug, such as HPPH, that is absorbed by tumor cells. The drug becomes active when it is exposed to light, and kills tumor cells. HPPH may be effective in killing precancerous cells and tumor cells. PURPOSE: This randomized phase II trial is studying how well photodynamic therapy with HPPH works in treating patients with precancerous esophageal conditions or stage 0 or stage I esophageal cancer.
RATIONALE: Chemoprevention is the use of certain drugs to keep tumors from forming, growing, or coming back. Zoledronate may prevent the growth of cervical cancer by blocking blood flow to cervical intraepithelial neoplasia cells. The use of zoledronate may keep cancer from forming. PURPOSE: This randomized is studying how well zoledronate works in treating patients with cervical intraepithelial neoplasia 2/3 or 3.
RATIONALE: Epoetin alfa may cause the body to make more red blood cells. It is used to treat anemia caused by cancer and chemotherapy. PURPOSE: This randomized phase II trial is studying how well epoetin alfa works in treating patients with anemia who are undergoing chemotherapy for cancer.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of fish oil and/or green tea may prevent prostate cancer. PURPOSE: This randomized clinical trial is studying how well a fish oil and/or green tea supplement works in preventing prostate cancer in patients with prostatic intraepithelial neoplasia or who are at risk for developing prostate cancer.
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and busulfan, before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the side effects of giving busulfan and fludarabine together with total-body irradiation and to see how well they work in treating patients who are undergoing a donor stem cell transplant for hematologic cancer.
RATIONALE: Drugs used in chemotherapy, such as 17-N-allylamino-17-demethoxygeldanamycin (17-AAG), work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well 17-AAG works in treating patients with systemic mastocytosis.
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer form forming, growing, or coming back. Vaccines may help the body build an effective immune response against human papillomavirus and may be effective in preventing cervical intraepithelial neoplasia or cervical cancer. It is not yet known whether human papillomavirus vaccine is more effective than hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer. PURPOSE: This randomized phase III trial is studying human papillomavirus vaccine to see how well it works compared to hepatitis A vaccine in preventing cervical intraepithelial neoplasia or cervical cancer in younger healthy participants.
RATIONALE: Vaccines made from protein and DNA may help the body build an effective immune response to kill abnormal cells in the cervix. The use of vaccine therapy may prevent cervical cancer. PURPOSE: This phase I/II trial is studying the side effects and best dose of vaccine therapy and to see how well it works in preventing cervical cancer in patients with cervical intraepithelial neoplasia and human papillomavirus.
