Filter by:RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using either tamoxifen or anastrozole may fight breast cancer by blocking the use of estrogen. It is not yet known whether tamoxifen is more effective than anastrozole in preventing breast cancer after surgery for ductal carcinoma in situ. PURPOSE: This randomized phase III trial is studying how well adjuvant tamoxifen works compared to anastrozole in treating postmenopausal women who have undergone surgery to remove ductal carcinoma in situ.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of or treat early cancer. SGN-00101 may be effective in preventing the development of cervical cancer in patients with cervical intraepithelial neoplasia. PURPOSE: This randomized phase II trial is studying how well SGN-00101 works in preventing cervical cancer in patients with cervical intraepithelial neoplasia and human papillomavirus.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation during surgery followed by external-beam radiation to the entire breast may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of radiation therapy during surgery followed by whole-breast radiation therapy in treating women who have undergone lumpectomy for ductal carcinoma in situ or invasive breast cancer
Vaccines made from antigens may make the body build an immune response to kill abnormal cervical cells and may be effective in preventing cervical cancer. Randomized phase II trial to study the effectiveness of vaccine therapy in preventing cervical cancer in patients who have cervical intraepithelial neoplasia
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Tamoxifen may fight breast cancer by blocking the use of estrogen. Anastrozole may fight breast cancer by decreasing estrogen production. It is not yet known whether anastrozole is more effective than tamoxifen in preventing the recurrence of breast cancer. PURPOSE: This randomized phase III trial is studying anastrozole to see how well it works compared to tamoxifen in preventing the recurrence of breast cancer in postmenopausal women with ductal carcinoma in situ who are undergoing lumpectomy and radiation therapy.
RATIONALE: Diagnostic procedures such as cystoscopy may improve the ability to detect cancer and to determine the extent of disease. PURPOSE: Diagnostic trial to compare the effectiveness of cystoscopy using hexyl 5-aminolevulinate and two light sources in detecting carcinoma in situ in patients who have bladder cancer.
If you are a male 30 years of age or older and have a positive diagnosis of high grade (II or III) prostate Intraepithelial Neoplasia (PIN) or have had an abnormal/suspicious prostate biopsy, you may be eligible for this study. This is a study of an investigational medication that may reduce high grade PIN and prevent the occurrence of prostate cancer. This study is currently enrolling up to 500 men at approximately 60 locations in the United States.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of eflornithine may be an effective way to prevent the recurrence of or further development of cervical cancer. PURPOSE: Randomized phase II trial to determine the effectiveness of eflornithine in preventing cervical cancer in patients who have cervical intraepithelial neoplasia.
Phase I trial to study the effectiveness of photodynamic therapy with lutetium texaphyrin in treating patients who have cervical intraepithelial neoplasia. Photodynamic therapy uses light and drugs such as lutetium texaphyrin that make abnormal cells more sensitive to light and may kill abnormal cells in the cervix and prevent the development of cervical cancer
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. It is not yet known if radiation therapy is more effective than observation, with or without tamoxifen, in treating ductal carcinoma in situ. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with that of observation, with or without tamoxifen, in treating women who have ductal carcinoma in situ.
