At the time of diagnosis of patients with CML, splenomegaly is the most common finding on physical examination.[10] The spleen may be enormous, filling most of the abdomen and presenting a significant clinical problem, or the spleen may be only minimally enlarged. In about 10% of patients, the spleen is neither palpable nor enlarged on splenic scan.

The median age of patients with Ph1-positive CML is 67 years.[11] While the median survival used to be 4 to 6 years, with the advent of the new oral therapies, the median survival is expected to approach normal life expectancy for most patients, although it is still too soon to say this definitively.
