Active clinical trials for "Leukemia"

RATIONALE: Giving chemotherapy before a donor stem cell transplant helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. It is not yet known whether donor stem cell transplant is more effective with or without chemotherapy in treating primary myelodysplastic syndrome. PURPOSE: This phase III trial is studying how well donor stem cell transplant given with chemotherapy works and compares it with donor stem cell transplant without chemotherapy in treating children with primary myelodysplastic syndrome.

The primary goal of this study is to provide comprehensive and objective information on impairments of musculoskeletal health, sensory function, and fitness among a large group of childhood ALL survivors, and to define high risk groups by assessing treatment factors that contribute to impaired function. This study includes a direct, objective evaluation of musculoskeletal function, sensory capacity, fitness, and physical activity patterns among adults who were treated for childhood ALL at St. Jude Children's Research Hospital (SJCRH) between 1980 and 1999. Among 899 ALL survivors, all of whom are eligible for an institutionally funded clinical study of medical late effects, the study will recruit 364 to participate in our evaluations. The study will also recruit 364 individuals for a comparison group, frequency matching on race/ethnicity, age and gender.

The allograft of marrow in its technique of reference (myélo-ablative (MA) condition by cyclophosphamide and total body irradiation (TBI) with strong amounts) therapeutic is recognized acute myeloid leukaemia (AML) of the adult for the patients of less than 55 years, because it offers chances of cure higher than chemotherapy or the auto-graft. However, mortality related to the traditional graft is approximately 30% to 1 year. The recent use of the non-myélo-ablative graft (NMA), in which the anti-leukaemia effect rests exclusively on the allogenic effect "graft-versus-leukaemia" makes it possible to obtain among patients of more than 55 years in complete reemission (CR), survivals without relapses comparable with the traditional allograft among patients of more than 35 years. The major interest of NMA graft is to reduce early mortality related to the graft. This reduction should be all the more significant as the patient is younger, and thus bring to a better survival. There is not, at the present hour, of prospective comparative study of the two procedures of graft. Taking into account the results observed after NMA graft among patients of more than 55 years, and taking into account the toxicity of the standard graft between 35 and 55 years, it is essential to now compare the 2 approaches among patients who do not have a counter-indication for one or the other, in the age bracket where the toxicity of the traditional graft is highest.

The purpose of this study is to determine if C-Reactive Protein levels are predictive for complications post transplant.

Evaluation of safety profile and tolerability of MabThera (rituximab) in combination with chemotherapy (fludarabine and cyclophosphamide) in the treatment of Chronic Lymphocytic Leukemia (CLL).

This study is intended for Chronic Lymphocytic Leukemia patients who have already undergone a first or second treatment with drugs named bendamustine and rituximab. It will observe the results of this treatment and evaluate its efficacy and side effects.

Physical Activity as a Self-Management Approach to Improve Health Outcomes in Acute Myeloid Leukemia

Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults in Western countries; it is stratified as a subtype of indolent lymphoid malignancy with a long but slowly progressive nature history. However, the clinical course of CLL actually varies widely. Thus, many clinical and molecular features have been identified for outcome predictions. The accurate predictions of prognosis through those factors help for the decision making on the treatment, i.e. to treat patients of high risk of early progression or poor overall survival (OS) with alternative or investigational therapies, while to avoid unnecessary over-treatment for low-risk patients. CLL is much less prevalent in Eastern countries; presently, most available data on CLL are derived mainly from Western countries. However, a previous report concerning the epidemiology of CLL in Taiwan revealed a drastic increase in the age-adjusted incidence of CLL, a trend not found in Western countries where the incidence rate of CLL remained steadily stable over time. In addition to this epidemiological difference, a population-based analysis has found the overall outcome of CLL, estimated by relative survivals, is steadily much poorer in Taiwanese patients than in US Caucasians. In another report about the cytogenetic profiles in a small cohort of CLL patients in Taiwan, a novel cytogenetic abnormality was found to correlate with poorer outcomes. These reports suggest the existence of ethnic differences in the disease natures of CLL between the East and the West. To delineate the possible underlying racial differences, especially in the molecular prognostic profiles that might underlie the outcome disparity between Taiwanese and western CLL patients, a comprehensive surveillance of the molecular profiles for CLL in Taiwan is of importance. In this study, we are going to enroll around 250 CLL patients; their clinical parameters will be recorded, their blood samples will be collected for a panel of molecular and cytogenetic factor studies. The molecular markers to be tested in this project include (but not limited to) cytogenetic abnormalities by fluorescent-in-situ hybridization (FISH), immunoglobulin heavy chain variable region (IGHV) hypermutation status, gene mutations for Notch1, SF3B1, p53, MyD88, and BIRC3, and the expressions for ZAP70 and stem cell factor (SCF). These proposed markers include not only the conventional prognostic markers derived from Western studies, and also some novel explorations from our preliminary results, such as SCF and trisomy 3. Through this study, a comprehensive profile of CLL in Taiwan will be established to identify the characteristics of CLL in Taiwanese patients and to address the underlying factors of ethnic differences in the disease nature and outcomes of this disease.

The purpose of this observational study is to provide data on the incidence and severity of infusion-related reactions during and immediately following each infusion of VYXEOS during the first induction.

To find possible therapeutic targets to help prevent long-term brain and behavioural side effects in survivors of childhood leukemia that may have been caused by chemotherapy (Treatment-Related late Adverse Neuro-Cognitive Effects: TRANCE). The study hypothesis is that genetic variations of the elements in the folate-related cycles and methotrexate disposition networks are associated with the deficit phenotype (TRANCE) of childhood leukemia survivors.
