Overview
There is insufficient evidence to recommend routine screening for myelofibrosis and there is no screening test currently available for the disease. Routine blood work can be used to check the blood cell counts which can further warrant a bone marrow biopsy.
Screening
- There is insufficient evidence to recommend routine screening for myelofibrosis.
- Blood cell counts can be determined and monitored for any irregularity which can then further warrant a bone marrow biopsy.
- According to 2008 World Health Organization (WHO) classification of myeloproliferative neoplasms, JAK2V617F is the most prevalent mutation with approximately 60% of the primary myelofibrosis (PMF) patients carrying this mutation. This trend is followed in frequency by the mutations in myeloproliferative leukemia virus (MPL) and calreticulin (CALR) genes.[1][2][3]
- Patients can be screened for the above mentioned mutations based on this data.
