Filter by:RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining peripheral stem cell transplantation with combinations of drugs may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of high-dose combination chemotherapy followed by peripheral stem cell transplantation or autologous bone marrow transplantation in women with stage II breast cancer with eight or more positive axillary lymph nodes and in women with stage III or metastatic breast cancer.
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Vaccines made from a patient's tumor tissue may make the body build an immune response to kill tumor cells. Chemotherapy combined with vaccine therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining cyclophosphamide with tumor cell vaccine in treating patients who have metastatic cancer or cancer at high risk of recurrence.
Tumor resistance to anti-cancer drugs is a major problem in cancer treatment. Studies have found that a protein (P-glycoprotein) on some cancer cells pumps chemotherapy drugs out of the cells, reducing treatment effectiveness. In laboratory tests, an experimental drug called XR9576, has blocked pumping by this protein. It is being used in this study to try to increase the amount of the anti-cancer drug vinorelbine, in cancer cells. Vinorelbine has been shown in several clinical trials to be effective against some advanced cancers, including breast, lung and ovarian, and is one of the drugs pumped out of tumor cells by P-glycoprotein. Patients with cancer 18 years and older may be eligible for this study. Candidates will be screened with tests that may include blood and urine tests, electrocardiogram, echocardiogram, CT scans, X-rays, and nuclear medicine studies. A tumor biopsy may be done for diagnostic or research purposes. Study participants will undergo tumor imaging with the radioactive drug Tc-99m Sestamibi. This drug accumulates in tumor cells and is eliminated from them in much the same way that some cancer drugs are eliminated from cells. The drug is injected into a vein and a series of pictures are taken with a gamma camera. After this baseline scan, patients will receive a dose of XR9576 and undergo a second scan 24 hours later. The scan will show whether XR9576 affects the accumulation and elimination of Sestamibi in tumor cells. This procedure may provide a way to monitor cancers for evidence of chemotherapy resistance and show if XR9576 can improve the effectiveness of therapy. At least 10 days after the baseline and XR9576 scans, patients will begin the first of 3 or more 21-day cycles of vinorelbine treatment. On days 1 and 8 of each cycle, patients will receive a 30-minute infusion of XR9576 intravenously (through a vein) followed by vinorelbine, infused over a 6- to 10-minute period. (In some patients, XR9576 will be administered before only one of the two vinorelbine dosages.) Physical examination, blood tests, and other procedures may be done periodically to monitor treatment.
This research study is designed to work in cooperation with another study being conducted by the National Cancer Institute. The National Cancer Institute (NCI) is studying the effects of a drug called raloxifene on premenopausal women believed to have a high risk of developing breast cancer (98-C-0123). In this study, researchers are interested in learning about the effects of raloxifene on the uterus and ovaries of the women participating in the NCI study. To do this researchers plan to conduct ultrasounds on the patients enrolled in the NCI study. In addition researchers plan to take samples of the lining of the uterus in these patients (endometrial biopsy) if found to be necessary. The purpose of this study is to determine the reproductive effects of raloxifene on women who have normal functioning ovaries by taking ultrasounds of the ovaries and lining of the uterus (endometrium).
In 1997, the Genetics Department of the NCI Medicine Branch helped establish a breast cancer genetics program at the National Naval Medical Center s Breast Care Center. Genetic education, counseling, and germline testing for BRCA1 and BRCA2, two genes which confer increased lifetime risks for breast and ovarian cancer, were offered under a Navy IRB-approved study. Sixty participants received education and counseling on that protocol, 49 of whom chose to have genetic testing. The education and counseling, provided by oncology nurses trained in cancer genetics, focused on preparing participants to make well-informed decisions about testing. Included were information on cancer and genetics; hereditary breast/ovarian cancer syndrome; risks, benefits and limitations of BRCA1/BRCA2 testing; and screening and risk reduction options for high-risk individuals. Through our experience with this study, we devised two different methods of providing this information. Both of these methods were well received and appear to be equally effective, as measured by knowledge assessments before and after the sessions and subjective evaluation by the participants. We will now study them in a randomized fashion in the current protocol, to better evaluate whether one method is preferable. Ultimately we hope to be able to make recommendations that will allow for access to genetic education and counseling for more individuals in a more cost efficient manner.
This is a dosage escalation study to estimate the maximum tolerated dose of 9-cis-retinoic acid given in combination with tamoxifen. Groups of 3 to 6 patients receive oral 9-cis-retinoic acid daily for 4 weeks, after which daily oral tamoxifen is added to the regimen. Patients continue treatment for up to 28 weeks, with tamoxifen continued after the study if medically appropriate.
This protocol is to provide follow-up medical/surgical visits for DCS patients who are long term survivors and may not currently be a participant entered on an active research protocol. No investigational treatments or standard treatments will be administered on this protocol.
Stage III patients may begin therapy prior to or following surgery. Patients with undrainable significant third space fluid collection (e.g., pleural effusions, ascites) are entered directly on Consolidation. Patients receive induction chemotherapy with methotrexate and fluorouracil every 2 weeks for 4 courses. Patients then receive two 3-week courses of consolidation therapy with cyclophosphamide, followed by daily granulocyte colony-stimulating factor until completion of leukapheresis. Patients next receive myeloablative doses of thiotepa followed by stem cell rescue and granulocyte colony-stimulating factor. After hematopoietic reconstitution, patients receive 24-hour infusions of paclitaxel every 3 weeks for 4 doses, followed by doxorubicin or vinblastine every 3 weeks for 4 doses. Patients are then evaluated for additional therapy (surgery, radiotherapy, or hormonal therapy) as appropriate. Patients are followed every 3 months for 1 year, then every 6 months.
This is a dosage escalation study to estimate the maximum tolerated dose of staurosporine analogue UCN-01. Groups of 3 to 6 patients receive a 72-hours intravenous continuous infusions of UCN-01 from day 1 to day 4 of each cycle the first cycle only, and over 36-hours on subsequent cycles. The side effects are allowed to disappear for up to 28 days. This cycle is repeated after evaluations and follow-ups, which are every 4 weeks, as long as the patient benefits.
This is a pilot feasibility trial of AC (Adriamycin, cyclophosphamide) chemotherapy with G-CSF (filgrastim) followed by infusional Taxol (paclitaxel) as adjuvant treatment for patients with high risk stage II and stage III breast cancer. Cycles will be 14 days in duration. After 3 fourteen day cycles of AC with filgrastim, patients will be treated with 3 fourteen day cycles of 96 hour infusional paclitaxel. The goal of this study will be to assess the toxicity and feasibility of administering dose-intensive AC chemotherapy followed by infusional paclitaxel in 14 day cycles.
