Active clinical trials for "Preleukemia"

Myelodysplastic syndrome (MDS) is a group of clonal haematopoietic stem cell disorders characterized by ineffective haematopoiesis leading to cytopenia, with a significant risk of progression to acute myeloid leukaemia (AML). Progression to AML and resistance to hypomethylating agents (HMA) are important unmet clinical needs. The pathophysiology of MDS and its progression to AML involve cytogenetic, genetic and epigenetic aberrations, and hence better understanding of the molecular landscape of MDS has important clinical implications. Also, future treatment strategies for MDS may involve exploitation of genetic information in designing more effective therapy encompassing single agents or combinatorial approaches. The proposed cohort study aims to establish a registry of clinical and genomic registry of MDS and secondary AML in Asian patients, which allows the establishment of the mutational profile of patients and prognostic model for survival, as well as exploration of treatment strategies and prediction for treatment response.

This is a prospective, single center, single-arm, phase 2 study. The aim of this study is to evaluate the efficacy and safety of Luspatercept for Patients with Lower-risk Myelodysplastic Syndromes (MDS).

A single center, prospective, one arm clinical study to assess the tolerance and effectiveness of total body irradiation and cladribine in adult patients diagnosed with AML( acute myeloid leukemia) and myelodysplastic syndromes.

The purpose of this study is to estimate the potential benefit of early and continued palliative care (PC) consultation on end of life issues.

The goal of this clinical trial is to explore the mechanism of Yisui Granule(YSG) in the treatment of myelodysplastic syndrome(MDS) through demethylation. Under the same condition of basic western medicine treatment, the treatment group used the same traditional Chinese medicine decoction pieces as YSG, and the control group was given placebo. Through a randomized controlled clinical study, we focused on observing the effects of MDS patients on clinical symptoms (including single symptom), fatigue relief, quality of life, peripheral blood picture, blood transfusion interval and blood transfusion volume, and measured the expression of DNMTs, the expression and methylation level of Wnt3a、β-catenin、SFRP and other indicators, as well as cytokines, were used to explore the mechanism of YSG in the treatment of MDS through demethylation.

Blood cancers occur when the molecules that control normal cell growth are damaged. Many of these changes can be detected by directly examining parts of the cancer or cells in blood. Several alterations that occur repeatedly in certain types of blood cancers have already been identified, and these discoveries have led to the development of new drugs that target those alterations. More remain to be discovered. Some of these abnormalities include alterations in genes. Genes are the part of cells that contain the instructions which tell the investigators bodies how to grow and work, and determine physical characteristics such as hair and eye color. Genes are composed of DNA letters that spell out these instructions. Studies of the DNA molecules that make up the genes are called "molecular" analyses. Molecular analyses are ways of reading the DNA letters to identify errors in genes that may contribute to an increased risk of cancer or to the behavior of the cancer cells. Some changes in genes occur only in cancer cells. Others occur in the genes that are passed from parent to child. This research study will examine both kinds of genes. The best way to find these genes is to study large numbers of people. The investigators expect that as many 1000 individuals will enroll in this study. This research study is trying to help doctors and scientists understand why cancer occurs and to develop ways to better treat and prevent it. To participate in this study the participant must have cancer now, had it in the past, or are at risk of developing cancer. The participant will not undergo tests or procedures that are not required as part of their routine clinical care. The investigators will ask the participant to provide an additional sample from tissue that is obtained for their clinical care including blood, bone marrow, or tissue sample. The investigators will also ask for a gentle scrape of the inside of their cheek, mouthwash or a skin sample to obtain their germline DNA

RATIONALE: Gathering information about older patients with cancer may help the study of cancer in the future. PURPOSE: This research study is gathering information from older patients with cancer into a registry.

Patients with clonal cytopenia of undetermined significance (CCUS) and lower-risk myelodysplastic syndromes (MDS) have a life expectancy of 5 to 10 years. Mortality in these patients results from progression of disease to higher-risk MDS or acute myeloid leukemia (AML) and cardiovascular events. Currently there are no FDA-approved treatments with the potential to improve survival of patients with CCUS and lower-risk MDS. Statins are an appealing class of drugs to consider in this situation as preclinical data support their potential to suppress progression of myeloid malignancy, and they have a well-established role in prevention of major cardiovascular events. This is a pilot study to explore the role of statins in treatment of patients with CCUS and lower-risk MDS. In this study, change in variant allele frequency (VAF) of somatic mutations present at diagnosis will be used as a surrogate marker of response to statin therapy. The hypothesis is that the use of statins at diagnosis of CCUS or lower-risk MDS will delay or prevent the expected increase in the VAF of somatic mutations over time.

Myelodysplastic syndromes (MDS) are acquired clonal stem cell diseases characterized by hematopoietic cell dysplasia, cytopenia, and the risk of progression to acute myeloid leukemia. In addition to clonal changes in the hematopoietic stem and progenitor cells itself, growing evidence suggests that inflammatory and metabolic changes in the bone marrow microenvironment play an important role in disease development and maintenance of the malignant clone. The positive impact of dietary interventions (e.g. fasting) and physical activity on inflammation and metabolic parameters could be shown in various benign inflammatory disease entities (e.g. atherosclerosis, chronic renal insufficiency, cystic fibrosis etc.). The aim of this study is to describe the hematological, metabolic, inflammatory, and microbiological changes after combined lifestyle-modifying interventions (outpatient physiotherapy and fasting mimicking diet (FMD) in patients with low-risk MDS.

This pilot phase II trial studies how well high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil work in preventing graft versus host disease in patients with hematological malignancies undergoing myeloablative or reduced intensity donor stem cell transplant. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving high dose cyclophosphamide, tacrolimus, and mycophenolate mofetil after the transplant may stop this from happening.
