Chronic eosinophilic leukemia (CEL) is a chronic myeloproliferative disorder of unknown etiology in which a clonal proliferation of eosinophilic precursors results in persistently increased numbers of eosinophils in the blood, bone marrow, and peripheral tissues. In CEL, the eosinophil count is greater than or equal to 1.5 × 109 /L in the blood. To make a diagnosis of CEL, there should be evidence for clonality of the eosinophils or an increase in blasts in the blood or...
Other conditions may cause the same symptoms. Talk to your child's doctor if your child has any of these problems.
Lung late effects in childhood cancer survivors may occur slowly over time and or there may be no symptoms. Sometimes lung damage can be detected only by imaging or pulmonary function testing. Lung late effects may improve over time.
Certain tests and procedures are used to detect (find) and diagnose health problems in the lung.
These and other tests and procedures may be used to detect or diagnose lung late effects:
Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
Pulmonary function test (PFT): A test to see how well the lungs are working. It measures how much air the lungs can hold and how quickly air moves into and out of the lungs. It also measures how much oxygen is used and how much carbon dioxide is given off during breathing. This is also called lung function test.
Talk to your child's doctor about whether your child needs to have tests and procedures to check for signs of lung late effects. If tests are needed, find out how often they should be done.
Health habits that promote healthy lungs are important for survivors of childhood cancer.
Childhood cancer survivors with lung late effects should take care to protect their health, including:
