NCT00436410
RATIONALE: Biological therapies, such as tumor necrosis factor, may stimulate the immune system in different ways and stop tumor cells from growing. Studying tumor necrosis factor in samples of tumor tissue and healthy tissue from patients with cancer in the laboratory may help doctors learn how tumor necrosis factor works in tumor tissue and healthy tissue. PURPOSE: This clinical trial is studying tumor necrosis factor in patients undergoing surgery for primary cancer or metastatic cancer .
NCT00001837
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).
NCT00001944
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.
