Georgiana Toma: From Cytoreduction to Vascular Protection in Essential Thrombocythemia

Georgiana Toma, Hematology resident at the University Emergency Hospital of Bucharest, shared a post on LinkedIn:

“To my colleagues in internal medicine and neurology

We have all managed patients with ‘controlled’ platelet counts who still suffer from devastating recurrent strokes or systemic thrombotic events.

The results of the SURPASS-ET study (published in The Lancet Haematology, 2026) change the conversation from simple cytoreduction to vascular protection and disease modification.

Ropeginterferon alfa-2b

For our patients resistant to hydroxyurea, the comparison between Ropeginterferon alfa-2b and Anagrelide reveals a massive shift in the safety-efficacy balance:

  • Vascular Risk: Complications (including cerebral infarction) were significantly lower with Ropeginterferon compared to Anagrelide.
  • Safety Profile: Half the rate of Serious Adverse Events (14 percent versus 30 percent).
  • Durable Response: A staggering 43 percent durable response at 12 months versus only 6 percent for anagrelide (p less than 0.0001).

Why this matters for your practice:

  1. Ropeginterferon significantly reduces the JAK2 (V617F) allelic burden. This suggests we can actually prevent the long-term transformation into Myelofibrosis or Acute Leukemia—something traditional therapies struggled to achieve.
  2. Neurological Protection: For Neurologists, this offers a potent tool to reduce the risk of cerebral infarction and hemorrhage in high-risk MPN patients.
  3. Fewer Side Effects: Better tolerability means higher compliance and fewer hospitalizations for drug-related complications.

The Bottom Line

We are moving toward a new standard where molecular remission is the goal.

By targeting the underlying biology of Myeloproliferative Neoplasms, we aren’t just treating a lab value; we are protecting our patients’ vascular future.”
