These conditions can affect people of any age and are often discovered by chance. MPNs are classed by the World Health Organisation as blood cancers because the bone marrow produces blood cells in an uncontrolled way.
We run a specialist MPN service for patients with the following conditions:
- Essential thrombocythaemia (ET)
- Polycythaemia vera (PV)
- Primary myelofibrosis (PMF)
- Chronic myeloid leukaemia (CML)
- Chronic neutrophilic leukaemia (CNL)
- Chronic eosinophilic leukaemia (CEL) and other eosinophilic disorders
- Mastocytosis
We mainly care for patients from the local Newcastle area, but we can also see patients from further afield for a second opinion after referral from their local haematologist.
Clinics
We run three specialist clinics within the Northern Centre for Cancer Care:
- Thursday afternoon clinic
- Wednesday afternoon CML clinic (pharmacist/nurse-led)
- Friday morning MPN clinic (pharmacist/nurse-led)
Some patients may be referred to other teams within haematology, such as the obstetric haematology clinic or the bone marrow transplant team. Patients aged 25 and under will also be offered support from the teenage and young adult service.
In addition, we use the haematology day unit (ward 36) for procedures such as bone marrow biopsies or venesection, when transfusions or intravenous medications are needed, or when patients need to be seen outside of clinic.
