Active clinical trials for "Recurrence"

The aim of this study is to establish a platform of detecting and sorting circulating tumor stem cells from peripheral blood in HCC patients; to investigate the relationship between circulating tumor stem cells and their effects on postoperative recurrence and metastasis, in order to provide a new therapeutic target for hepatocellular carcinoma treatment.

Patients with acute leukemia relapsing after allotransplant and who respond to anti-leukaemia interventions are at high-risk of a second relapse. Previous studies from investigators reported an association between a positive minimal residual disease (MRD)-test after transplant and an increased risk of subsequent relapse. Also, patients developing chronic graft-versus-host disease (GvHD) after receiving DLI (donor lymphocyte infusion)for leukemia relapse after a first allotransplant have a lower likelihood of a second relapse compared with similar patients not developing chronic GvHD. And, our previous study also reported patients with chronic GvHD after DLI was associated with a greater frequency of a negative MRD-test and lower likelihood of subsequent relapse compared with similar persons not developing chronic GvHD. Based on these data the investigators designed a randomized control study to determine whether giving additional consolidation chemotherapy and DLI might decrease likelihood of second relapse in persons without chronic GvHD or with a positive MRD-test after initial post-relapse therapy with induction chemotherapy and DLI.

The purpose of the study is to compare the recurrence of endometriotic cyst in patients taking Dienogest or Microgynon after conservative surgery.

The investigators evaluated the efficacy of a single early intravesical instillation of doxetaxel in the prevention of bladder recurrence after nephroureterectomy or distal ureterectomy for upper urinary tract urothelial carcinoma (UUT-UC).

In this study, a randomized, prospective, multicenter, open cohort study was conducted to investigate patients with acute leukemia (14～60-year-old) with different ATG doses (10 mg / kg and 12.5 mg / kg ) in fludarabine, busulfan, cyclophosphamide and antilymphocyte globulin (FBCA) pretreatment protocol of Haploidentical hematopoietic stem cell transplantation (haplo-HSCT). The purpose is to compare the incidences of chronic graft vs host disease (cGVHD) in haplo-HSCT recipients receiving different dose ATG and one year leukemia relapse after transplantation. The main objective was to investigate the optimal dose of ATG for decrease cGVHD and not increase one year relapse leukemia after haplo-HSCT. Its significance is to provide evidence-based medical evidence to reduce the occurrence of cGVHD and to improve the quality of life of patients with haplo-HSCT.

The purpose of this study is to study the effect of fingolimod on cardiac autonomic regulation in patients with relapse-remitting multiple sclerosis. This will be done by measuring heart rate variability from the 24-hour Holter recording and myocardial ventricular repolarisation patterns from the 12-lead electrocardiogram tracings. The fingolimod treatment is prescribed according to the accepted drug label.

The main purpose of our study is to assess the effect of a lifestyle intervention combining weight control, diet and physical activity on the risk of recurrences among breast cancer patients with non-metastatic tumours in terms of 5-year cumulative incidence of recurences.

The objective of this study is to determine the mechanisms of stroke in patients with Intracranial Atherosclerotic Disease (IAD) by specifically evaluating limitations of antegrade flow through the stenotic artery, distal tissue perfusion to the affected territory, and artery-to-artery embolism. The hypothesis is that non-invasive imaging biomarkers that stratify stroke risk and distinguish mechanisms of IAD. This prospective multicenter study will enroll 175 patients with recently symptomatic high-grade IAD. Patients will be studied within 21 days of the index event (allowing appropriate time to arrange for diverse imaging modalities), with the following advanced neuroimaging techniques to elucidate mechanisms of recurrent ischemia: Quantitative magnetic resonance imaging (QMRA) to assess volumetric flow rate through the stenotic artery. Magnetic resonance perfusion weighted imaging (PWI-MRI) to determine distal tissue perfusion. Vasomotor reactivity by Transcranial Doppler using the breath-holding technique (BHI-TCD) to assess compensatory flow characteristics to the territory distal to the affected artery; Transcranial Doppler with embolic signal monitoring to evaluate artery-to-artery embolism that reflects plaque instability. Patients will receive standardized medical management and its effectiveness on blood pressure, lipid, and glycemic control will be monitored. The primary outcome is recurrent stroke in the territory of the stenotic artery during a 1-year follow-up period; secondary outcomes are: a) new asymptomatic ischemic lesions on MRI in the distribution of the stenotic artery at 6-8 weeks, and b) transient ischemic attack (TIA) in the distribution of the stenotic artery during a 1-year follow-up period. Patients will be recruited at various sites that will be trained and certified on the imaging techniques employed. Raw imaging data will be interpreted centrally.

RATIONALE: Infection prophylaxis and management may help prevent cytomegalovirus (CMV) infection caused by a stem cell transplant. PURPOSE:This clinical trial studies infection prophylaxis and management in treating cytomegalovirus infection in patients with hematologic malignancies previously treated with donor stem cell transplant.
