Objective and Significance:
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). Recurrent mutations are found in over 85% of cases. Treatment of high-risk MDS involves the use of hypomethylating agents (HMA), and allogeneic haematopoietic stem cell transplantation (HSCT). Treatment with HMAs achieves response rate of about 40% in high-risk patients, and median duration of response of merely 9 to 15 months. HMA failure is associated with a dismal outcome and a median survival of less than 5 months. Therefore, progression to AML and resistance to HMA are important unmet clinical needs. Early prediction of leukemic progression and HMA resistance might improve outcome by early triage to HSCT. There is currently no well-established model incorporating clinicopathologic and genetic data for predicting leukemic transformation and HMA failure. Furthermore, there is a lack of large multicentre registry of clinical and genetic information in Asian patients with MDS.
To establish a prognostic model incorporating clinicopathologic and genetic data for Asian MDS patients, for the prediction of survivals, HMA resistance and leukemic transformation.
Clinical impacts include
Research Plan and Methodology:
Data on clinicopathologic features, cytogenetics, genetic mutation profile, disease progression and treatment outcome will be collected in a retrospective and prospective cohort of 1600 Asian patients with MDS. Mutations will be determined by next-generation sequencing using a myeloid gene panel comprising 69 genes of potential diagnostic, prognostic or therapeutic significance. The sample size of 1600 will establish a prognostic model integrating clinicpathologic, cytogenetic and molecular information.
Asian Myeloid Working Group (Hong Kong as the lead, Singapore, Taiwan, Thailand, Malaysia, Korea, the Philippines) has been established since May 2017 It is registered in ClinicalTrials.gov (ClinicalTrials.gov Identifier: NCT03169296).
