Asian Myeloproliferative Neoplasm (MPN) Registry

Study Overview
=================
Brief Summary
-----------------
This is a multinational, multicenter, prospective and retrospective, observational, cohort study of patients with myeloproliferative neoplasm.

Detailed Description
-----------------
This is a multinational, multicenter, prospective and retrospective, observational, cohort registry of patients with MPN. The registry mainly involves study centres in Asia including but not limited to Hong Kong, Singapore, Malaysia, Taiwan, Korea and Thailand. Clinicopathologic characteristics, cytogenetic characteristics, mutational characteristics, treatment characteristics, outcomes and survivals of Asian patients MPN diagnosed between 2010-2025 will be collected to establish clinical registry. Data on the clinicopathologic characteristics, cytogenetics, mutational profile, prognostic scoring treatment characteristics, responses to treatment, outcome and survivals will be collected through routine clinic visits and/or reviewing medical records. Data will be collected at diagnosis, and approximately every 6 months thereafter (for prospective data) and at progression until death/study termination.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to progression to secondary myelofibrosis (for PV and ET) | Measured in months, from date of diagnosis of MPN to date of documentation of secondary myelofibrosis (event), death (event) or latest follow-up (censor). Patient without an event will be censored at date last known to be progression-free | 10 years | 
| Progression-free survival (PFS) | Measured in months, from date of diagnosis of MPN to the date of the first MDS or AML or death due to any cause. Patient without an event will be censored at date last known to be progression-free and alive. | 10 years | 
| Overall survival (OS) | Measured in months from the date of diagnosis of MDS until the date of death due to any cause. Patient who is alive will be censored at the date last known alive | 10 years |
