Overview
If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
OR
Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
OR
Prognosis is generally excellent/good/poor, and the 1/5/10-year mortality/survival rate of patients with [disease name] is approximately [#]%.
Natural History, Complications, and Prognosis
Natural History
- The symptoms of CNL usually develop in the first/ second/ third decade of life, and start with symptoms such as ___.
- The symptoms of (disease name) typically develop ___ years after exposure to ___.
- If left untreated, [#]% of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
Complications
- The common complications of CNL include:[1][2]
- Predisposing to hemorrhage (intracranial hemorrhage as the most common cause of death in CNL patients)
- Progression of disease
- Blastic or leukemic conversion
- Treatment-related toxicity
Prognosis
Progression to acute myeloid leukemia may seen in 10-21.2% of patients with CNL.[3][4]
Prognosis is generally poor, and the 5-year survival rate of patients with CNL is approximately 28%.[4][5]
- The factors that can predict poor outcomes are:[6][7][8]
- white blood cell count>50,000 cells per microliter
- ASXL1 mutation
- Thrombocytopenia
- Advanced age
- Dependency to transfusion
- Peripheral blasts ≥ 1%
- Marrow blasts ≥ 10%
- Splenomegaly
- The indication of disease progression in CNL patients include:[9]
- Treatment-resistant
- Refractory neutrophilia
- Increasing in red blood cells
- Platelet transfusion dependency
- Deterioration of organomegaly
- Blast crisis
