There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known whether mastectomy, chemotherapy, and/or hormone therapy are more effective with or without radiation therapy in treating breast cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of mastectomy, chemotherapy, and/or hormone therapy with or without radiation therapy in treating women who have stage II breast cancer.
Respiratory failure in term newborns is associated with increased rates of death and long-term neurodevelopmental problems. This large international multicenter trial randomized newborns who had failed to respond to intensive care, including high levels of ventilator support, to receive either inhaled nitric oxide (iNO) or 100 percent oxygen to test whether iNO would decrease their risk of dying or requiring temporary lung bypass. Infants were followed during their initial hospitalization; their outcome was assessed at 18 to 24 mos of age.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of topotecan in treating patients who have recurrent ovarian epithelial or primary peritoneal cancer.
OBJECTIVES: I. Determine the effect of SYNSORB Pk therapy on mortality and frequency of severe extrarenal complications observed in children with acute stage E. coli-associated hemolytic uremic syndrome. II. Determine the effect of SYNSORB Pk therapy on the need for the duration of dialysis in these patients. III. Determine the effect of SYNSORB Pk therapy on the recovery of renal function and resolution of urinary abnormalities in these patients.
RATIONALE: EF5 may detect the presence of oxygen in tumor cells and help plan effective cancer treatment. PURPOSE: Phase I trial to study the effectiveness of EF5 in detecting the presence of oxygen in tumor cells of patients who are undergoing surgery or biopsy for breast, prostate, or cervical cancer or high grade soft tissue sarcoma.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of docetaxel in treating patients with recurrent or refractory ovarian or primary peritoneal cancer.
RATIONALE: Pilocarpine may help to relieve dry mouth in patients receiving opioids for cancer therapy. It is not yet known whether pilocarpine is more effective than no further treatment for this condition. PURPOSE: Randomized phase III trial to determine the effectiveness of pilocarpine in treating patients who have dry mouth caused by opioids.
RATIONALE: Vaccines made from tumor tissue may make the body build an immune response and kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of vaccine therapy in treating patients who have stage III or stage IV ovarian epithelial cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy consisting of liposomal doxorubicin and etoposide in treating patients who have recurrent or persistent ovarian, fallopian tube, or peritoneal cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy in treating patients with previously untreated stage III or stage IV ovarian or primary peritoneal cancer.
