The last stage of CML is called the blast phase (or blast crisis). This is when at least 20% of blood cells are immature, cancerous blast cells. Unfortunately, this stage carries the most serious prognosis of all CML phases. Here's what the research shows about survival in blast phase CML:
- Most people in blast phase survive an average of 7 to 10 months after diagnosis
- Overall survival is generally less than 12 months
- About 1% to 5% of people in chronic phase progress to blast phase each year
Certain factors can increase the risk of reaching blast phase, including:
- Not receiving TKI (targeted therapy) treatment
- Low platelet counts
- Being over age 60
- Certain genetic mutations Treatment options for blast phase CML do exist, including switching or adding TKI medications, chemotherapy, or palliative care to improve quality of life. A splenectomy (spleen removal) or clinical trials may also be considered.
It's really important to have an open conversation with your healthcare team about your specific situation, as individual factors can significantly affect your personal outlook.
