What is the purpose of performing a lumbar puncture in a child with leukemia?

Key points Doctors perform a lumbar puncture to see if leukemia has spread into the central nervous system (CNS). A lumbar puncture can be used to check the cerebrospinal fluid (CSF) for leukemic cells and to give chemotherapy that will reach the CNS. Your child will be sedated during the procedure.

What happens if leukemia spreads to spinal fluid?

The cells sometimes – though not often – spread to other organs, and can cause more symptoms there: headaches, seizures and vomiting if the leukemia has spread to the brain or spinal cord, or difficulty breathing if it has spread to the chest cavity, for example.

Can a lumbar puncture detect cancer?

A lumbar puncture can tell doctors whether blood cancer cells are present in the sample. In addition, the pressure in the fluid surrounding the brain and spinal cord can be measured to provide other important information.

Why would a child need a lumbar puncture?

Why does my child need a lumbar puncture? A lumbar puncture is needed to test the fluid around the brain and spinal cord. This test may be done to find out if a child has meningitis (a serious infection around the brain). Meningitis may be suspected in a baby with a fever, especially in babies less than one month old.

Is leukemia curable in child?

Most childhood leukemias have very high remission rates, with some up to 90%. Remission means that doctors see no cancer cells in the body. Most kids are cured of the disease. This means that they’re in permanent remission.

How does lumbar puncture diagnose leukemia?

A lumbar puncture can determine if the leukemia has spread to the cerebral spinal fluid (CSF). CSF is the fluid that flows around the brain and the spinal cord. During a lumbar puncture, a needle is used to take a sample of the CSF to look for leukemia cells.

How fast do leukemia symptoms progress?

Chronic leukemia usually gets worse slowly, over months to years, while acute leukemia develops quickly and progresses over days to weeks. The two main types of leukemia can be further organized into groups that are based on the type of white blood cell that is affected — lymphoid or myeloid.

What cancers show up in spinal fluid?

Cells from some types of cancer, such as breast cancer, lung cancer, and melanoma, can sometimes spread to your meninges, cerebrospinal fluid (CSF), or both. Your meninges are the layers of tissue that cover and protect your brain and spinal cord. They’re sometimes described as a jacket or envelope.

What do lumbar punctures test for?

A lumbar puncture can help diagnose serious infections, such as meningitis; other disorders of the central nervous system, such as Guillain-Barre syndrome and multiple sclerosis; or cancers of the brain or spinal cord.

What are the side effects of lumbar puncture?

What are the risks of a lumbar puncture?

• A small amount of CSF can leak from the needle insertion site.
• You may have a slight risk of infection because the needle breaks the skin’s surface, providing a possible way for bacteria to enter the body.
• Short-term numbness of the legs or lower back pain may be experienced.

How is a lumbar puncture used to check for leukemia?

A lumbar puncture can determine if the leukemia has spread to the cerebral spinal fluid (CSF). CSF is the fluid that flows around the brain and the spinal cord. During a lumbar puncture, the doctor uses a needle to take a sample of the CSF to look for leukemia cells.

How is spinal fluid tested for acute lymphocytic leukemia?

Spinal fluid test. A lumbar puncture test, also called a spinal tap, may be used to collect a sample of spinal fluid — the fluid that surrounds the brain and spinal cord. The sample is tested to see whether cancer cells have spread to the spinal fluid. In general, treatment for acute lymphocytic leukemia falls into separate phases:
