Great question! When ET progresses to myelofibrosis, it's actually called secondary myelofibrosis (or "post-ET myelofibrosis") — not primary myelofibrosis (PMF).
Here's the key difference:
- Primary myelofibrosis (PMF) — develops on its own, with no prior MPN

Great question! When ET progresses to myelofibrosis, it's actually called secondary myelofibrosis (or "post-ET myelofibrosis") — not primary myelofibrosis (PMF).
Here's the key difference:
- Primary myelofibrosis (PMF) — develops on its own, with no prior MPN
- Secondary myelofibrosis — develops as a progression from another MPN, like ET or PV The good news is that the symptoms and treatments for both types are generally the same, so information about PMF is still very relevant and useful for managing your condition.
It's always worth confirming with your doctor or hematologist how your specific situation compares, as they can tailor guidance to your personal history with ET.
