Cyclophosphamide Treatment Options in Texas

RATIONALE: Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of allogeneic umbilical cord blood transplantation in treating patients who have leukemia, lymphoma, or nonmalignant hematologic disorders.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Umbilical cord blood transplantation may be able to replace immune cells that were destroyed by the chemotherapy or radiation therapy that was used to kill cancer cells. PURPOSE: Phase II trial to study the effectiveness of umbilical cord blood transplantation plus combination chemotherapy in treating patients who have hematologic cancer or nonmalignant hematologic disease.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if chemotherapy given before surgery is more effective with or without docetaxel given before or after surgery for breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy using doxorubicin and cyclophosphamide with or without docetaxel in treating women who have stage II or stage III breast cancer.

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Thalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. Giving bortezomib together with cyclophosphamide, dexamethasone, and thalidomide may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with cyclophosphamide, dexamethasone, and thalidomide works in treating patients with newly diagnosed, previously untreated multiple myeloma.

The purposes of this study include: * Determination of the change in clearance of topotecan and topotecan lactone between day 1 and day 14 for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days. * Determination of the correlation between the activity of CYP3A4, as measured by the 14C- Erythromycin Breath Test (ERMBT), and topotecan/topotecan lactone clearance for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days. * Determination of the response rate to oral cyclophosphamide and oral topotecan in recurrent and/or refractory pediatric solid tumors. * Obtain additional safety data for the chemotherapy regimen, p.o. topotecan and p.o. cyclophosphamide x 14 days. * Report the frequency of severe toxicities associated with the level of CYP3A4 activity, as measured by the ERMBT, for patients receiving treatment with p.o. topotecan and p.o. cyclophosphamide x 14 days.

This research study measures the safety and efficacy of the combination of three drugs that are approved, Nipent, Rituxan and Cytoxan in the treatment of Chronic Lymphocytic Leukemia (CLL). These drugs are being given together for investigational purposes as the specific combination of these three drugs has not been approved for treatment of CLL by the FDA. Read Less
