Filter by:RATIONALE: Drugs used in chemotherapy, such as cisplatin, vincristine, bleomycin, carboplatin, and etoposide phosphate, 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. It is not yet known which combination chemotherapy regimen is more effective in treating germ cell tumors. PURPOSE: This randomized phase II trial is studying two different combination chemotherapy regimens to compare how well they work in treating male patients with germ cell tumors.
RATIONALE: Antiemetic drugs, such as aprepitant, granisetron, and dexamethasone, may help lessen or prevent nausea and vomiting in patients treated with chemotherapy. PURPOSE: This clinical trial is studying how well giving aprepitant together with granisetron and dexamethasone works in preventing nausea and vomiting in patients receiving cyclophosphamide before undergoing an autologous stem cell transplant.
High-dose chemotherapy (HD-CT) is able to circumvent platinum-resistance of resistant/refractory germ-cell tumors (GCTs), but expectancy of cure remains low. New strategies are needed with new drugs and a sequential approach. Patients with relapsed (but not absolutely refractory to Cisplatinum-based chemotherapy) poor-prognosis GCTs are scheduled to receive 2 cycles combining epirubicin and paclitaxel followed by 3 consecutive HD-CT supported by stem cell transplantation. One course will combine Taxol, 360 mg/m² + thiotepa, 720 mg/m², followed by two ICE regimens (Ifosfamide, 12 g/m², carboplatin, AUC 20, etoposide, 1500 mg/m²). This phase II study is designed as a Gehan method. The main objective of the study is the complete response rate. With this aim in view, it is planned to enroll in its first step 14 patients to insure that if no complete response (CR) is noticed, study would be stopped for inefficacy (i.e., a CR rate lower than 20%). If one or more CR are noticed, protocol specified that up to 45 patients will be included in order to reduce the confidence interval (CI) of the CR rate. Secondary objectives are the overall response rate (RR), the overall survival (OS) and the progression-free survival (PFS) rates, toxicity and toxic death rate. The statistical analysis is done in terms of intent-to-treat.
This pilot study will explore the relationship of Ochratoxin A (OTA) levels in patients with upper tract transitional cell (TCC), renal cell, and testicular cancers by measuring levels of OTA in serum and tumor samples. Dietary exposure will also be analyzed.
This is a study for patients with advanced testicular cancer. This research study involves treatment with oxaliplatin, paclitaxel, and gemcitabine, which is an investigational chemotherapy combination. This study is for patients who have not responded to standard cisplatin-containing chemotherapy or the cancer has returned after such treatment. This research is being done to assess the effectiveness of the proposed combination of medications for this type of cancer.
BACKGROUND: Evidence has emerged that patients cured with cisplatin-bleomycin chemotherapy from disseminated testicular cancer (TC) develop a large number of cardiovascular risk factors (CRF) several years later. Recently, we observed an increased incidence of cardiac events 10-20 years after chemotherapy, possibly as a result of increased occurrence of CRF. Additional cardiovascular damage was observed after treatment: disturbed diastolic function of the left ventricle, microalbuminuria and increased endothelial damage parameters. Furthermore, a metabolic syndrome (syndrome X) with insulin-resistance, dyslipidemia, hypertension and endothelial damage was found in about one third of our cured patients. The investigators hypothesize that endothelial damage and metabolic changes caused by the bleomycin and cisplatin chemotherapy are the main causes for the observed increase in cardiovascular disease in these young cancer survivors. Genetic susceptibility may be an important determinant of individual risk of toxicity in individual patients. PURPOSE: 1. To identify risk factors for cardiovascular disease (CVD) following testicular cancer. 2. To obtain insight into the pathway(s) of CVD development, by examining whether clinical CVD following testicular cancer is associated with a preceding unfavorable cardiovascular risk factor profile and/or with treatment-related factors. 3. To investigate genetic polymorphisms in pathogenetically important pathways that are potentially involved in the development of treatment related cardiovascular morbidity following testicular cancer. PATIENTS AND METHODS: Patients with non-seminomatous testicular cancer who have been uniformly treated with orchidectomy and cisplatin-bleomycin combination chemotherapy at the University Hospital Groningen, The Netherlands, since 1977 but before 2000 are eligible. 380 patients with non-seminomatous testicular cancer fulfill these criteria. A close routine follow-up of these patients after treatment has been done at the University Hospital Groningen. Clinical characteristics of these patients, treatment details including outcome and long-term follow-up are being registered systematically. From all patients who agree to participate assessment of their cardiovascular risk factors and the presence of subclinical cardiovascular damage will be performed by means of several measurement techniques. Also genomic DNA will be collected for studies on polymorphisms in pathogenetically important pathways. For the total cohort of patients several different late effects phenotypes of cardiovascular damage and cardiovascular risk factor patterns will be derived from the available data. These toxicity phenotypes will be used to select cases and controls from the total cohort to test candidate genetic polymorphisms on their association with occurrence of toxicity. The association of the different genetic polymorphisms with the toxicity phenotype will be estimated by comparing cases with different toxicity phenotypes with controls without that phenotype. POSSIBLE RESULTS This research will provide insight into the pathogenesis of cardiovascular disease after treatment for testicular cancer. The main outcome will be the possibility to select individually those patients who are likely to have an increased risk to encounter specific cardiovascular toxicity during or after chemotherapy treatment for TC. This will provide opportunities for the tailoring of potential toxic treatment and/or guide primary and secondary prevention strategies for serious side effects of chemotherapy treatment.
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: Alemtuzumab, tacrolimus, and methylprednisolone may be an effective treatment for graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This phase II trial is studying how well giving alemtuzumab together with tacrolimus and methylprednisolone works in treating acute graft-versus-host disease in patients who have undergone donor stem cell transplant.
This phase II trial is studying how well oxaliplatin works in treating young patients with recurrent solid tumors that have not responded to previous treatment. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop tumor cells from dividing so they stop growing or die.
RATIONALE: Understanding the emotional needs of spouses or others who are living with and caring for patients who have undergone stem cell transplantation may help improve the quality of life of both the caregivers and the patients. PURPOSE: This clinical trial is studying the emotional needs of caregivers of patients who have undergone stem cell transplant.
