Filter by:This is a phase III clinical trial for patients with potentially completely resectable primary retroperitoneal sarcoma. Patients who take part will be divided into two groups, a radiation therapy plus surgery group and a surgery alone group. Patients in the radiation therapy plus surgery group will receive radiation treatments as an outpatient. Surgery to try to remove the remaining tumor will be done after the radiation treatments are completed. Patients in the surgery alone group will have surgery to try to remove all tumor.
Phase II Study to evaluate the response on two blocks of topotecan and carboplatin
Positron Emission Tomography (PET) is a specialised nuclear medicine procedure that uses positron emitting radiolabeled tracer molecules to measure biological activity. The most common of these radiolabeled tracers is 18F-fluorodeoxyglucose (18F-FDG), which is used to determine abnormal glucose metabolism in tumours and other sites. It has general applications in all areas where abnormal glucose metabolism may be present including in circumstances such as differentiating the tumour from scar tissue; evaluating the presence of the tumour in light of rising tumour markers and normal morphological imaging techniques; and assessing response to therapy where other techniques are deemed to be unhelpful. The Cross Cancer Institute has recently been funded to establish a PET centre, and this study will evaluate the effectiveness, value and safety of PET scanning in a number of uncommon cancers in the Canadian health care environment.
RATIONALE: Drugs used in chemotherapy, such as methotrexate, trimetrexate glucuronate, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of trimetrexate glucuronate when given together with methotrexate and leucovorin in treating patients with refractory or recurrent osteosarcoma.
RATIONALE: A bone marrow transplant from a brother or sister may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. Colony-stimulating factors, such as G-CSF, cause the body to make blood cells. Giving G-CSF to the donor may help the body make more stem cells that can be collected for bone marrow transplant and may cause fewer side effects in the patient after the transplant. PURPOSE: This phase I/II trial is studying the side effects of donor bone marrow transplant and to see how well it works in treating young patients with cancer or a non-cancerous disease.
This study evaluates the safety and efficacy of a novel tyrosine kinase inhibitor, PTK787/ZK222584, in the treatment of GIST (gastrointestinal stromal tumor) that is resistant to imatinib mesylate (Gleevec). The study participants are required to have histologically confirmed GIST with prior imatinib treatment for metastatic GIST. is administered orally 1250 mg/day. Six patients will first enter the study. If clinical benefit is obtained in >1 of 6 patients, 9 and 30 additional patients will be entered into the protocol in two stages (a maximum of 45 patients will be entered). Patients who benefit from the study treatment will be treated with PTK787/ZK222584 until treatment failure.
In this study, patients who have been diagnosed with gastrointestinal stromal tumor (GIST) will be randomly allocated in a 1:1 ratio to receive imatinib (Gleevec) either for 12 or for 36 months following surgery. The study participants are required to have a histologically verified GIST with a high risk of GIST recurrence despite complete removal of all macroscopic GIST tissue at surgery. The high/very high risk of recurrence is defined as one of the following: 1) the largest tumor diameter is over 10 cm; 2) the mitosis count is high (over 10 mitoses per 50 high power microscope fields, HPFs); 3) the largest tumor diameter over 5 cm and the mitosis count is over 5/50 HPFs; 4) tumor spillage has taken place into the abdominal cavity at the time of surgery or following spontaneous tumor rupture. All study participants will receive imatinib 400 mg/day orally, but the duration of imatinib administration will be determined randomly (either for 12 or for 36 months). The study participants will be followed up using blood tests and computed tomography (or MRI) of the abdomen. The computed tomography examinations will be performed at 6 month intervals for a median of 5 years. A total of 280 patients will be entered into the study. The study hypothesis is that adjuvant imatinib may prevent some of the GIST recurrences, and that there may be a difference in the rate of GIST recurrence between the two groups.
RATIONALE: A peripheral stem cell, bone marrow, or umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving busulfan and melphalan with or without antithymocyte globulin before transplant and cyclosporine with methylprednisolone or methotrexate after transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects of donor stem cell transplant in treating young patients with relapsed or refractory solid tumors.
RATIONALE: Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving paclitaxel together with carboplatin works in treating patients with persistent or recurrent stage III or stage IV uterine cancer.
RATIONALE: Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying how well pemetrexed disodium works in treating patients with recurrent and unresectable or metastatic chondrosarcoma.
