Free Lambda Light Chain Multiple Myeloma

In igg kappa myeloma the myeloma cells produce an immunoglobulin made from two igg heavy chains bound to two kappa light chains.

Free lambda light chain multiple myeloma.

Multiple myeloma begins in the bone marrow where white blood cells are formed. Generally myeloma specialists do not treat patients differently based on their heavy or light chain myeloma type. Ninety seven patients with light chain disease lcd were studied. Myeloma cells make immunoglobulins.

Serum free lambda light chains14 30 normal range. There is research showing that lambda myeloma may be higher risk than kappa myeloma. Numerous studies have shown that responses to myeloma treatment can be evaluated through serum free light chain levels. In a study with 493 british patients diagnosed with multiple myeloma the sflc was evaluated for 17 of these patients and concluded that the sflc number was more indicative of response to therapy than was the involved immunoglobulin number such as levels of igg iga etc.

This type of myeloma is usually more severe than the classic kind. The most common type of myeloma is igg kappa. About 15 of patients have light chain myeloma. There are 2 types of light chains called kappa and lambda.

Light chain multiple myeloma is a type of multiple myeloma a cancer of the plasma cells. Light chain myeloma sometimes called bence jones myeloma. If you have been diagnosed with multiple myeloma a blood test called a serum free light chain assay freelite played an important role in your diagnosis and will continue to be important in. Multiple myeloma may be indicated by increased kappa free light chains and an increased kappa lambda ratio.

0 57 2 63 mg dl multiple myeloma may be indicated by increased lambda free light chains and a decreased kappa lambda ratio. The serum free light chain test can be used to determine light chain levels of disease so patients will want to track their light chain numbers. These immunoglobulins are made up of only one type of heavy chain g a d e or m and one type of light chain kappa or lambda. When the body detects an infection these white blood cells transform into plasma cells which create proteins called immunoglobulins also known as antibodies.

In this type of myeloma the myeloma cells secrete only light chain protein and no heavy chains. They only produce part of the immunoglobulin called the light chain. Light chain myeloma also known as light chain disease is a type of multiple myeloma in which the malignant bone marrow cells produce free monoclonal light chain proteins. About 20 out of 100 people with myeloma 20 do not produce complete immunoglobulins.
