Anderson Cancer Center found that a haemoglobin level of <12g/dL, total circulating lymphocyte count of >2.5 x 109/L, >0% immature myeloid cells, >10% bone marrow blasts causes a reduced overall survival. This data allows cases of CMML to be stratified into low, intermediate-1, intermediate-2 and high risk groups. These groups have median survival times of 24, 15, 8 and 5 months respectively. The Düsseldorf score
The Düsseldorf score stratifies cases using four categories, giving one point for each; bone marrow blasts ≥5%, LDH >200U/L, haemoglobin ≤9g/dL and a platelet count ≤100,000/uL. A score of 0 indicates a low risk group 1-2 indicates an intermediate risk group and 3-4 indicates a high risk group. The cumulative 2 year survival of scores 0, 1-2 and 3-4 is 91%, 52% and 9%; and risk of AML transformation is 0%, 19% and 54% respectively. Treatment
The treatment of CMML remains challenging due to the lack of clinical trials investigating the disease as its own clinical entity. It is often grouped with MDS in clinical trials, and for this reason the treatment of CMML is very similar to that of MDS. Most cases are dealt with as supportive rather than curative because most therapies do not effectively increase survival.
Cetirizine/pseudoephedrine (Zyrtec-D) is an antihistamine and decongestant formulation. It is a fixed-dose combination drug containing cetirizine hydrochloride and pseudoephedrine hydrochloride for symptoms related to seasonal allergic rhinitis. == References ==
