How is multiple myeloma classified?

Therefore, the myeloma can be classified by the type of light and heavy chains produced, such as IgG kappa, IgG lambda, IgA kappa, or IgA lambda, etc. The most common type of heavy chain produced in myeloma is IgG, followed by IgA and then IgD.

How many types of myeloma are there?

There are 2 main types of multiple myeloma, smouldering and active. Smouldering multiple myeloma doesn’t have signs and symptoms of the disease. Active multiple myeloma has signs and symptoms.

What are the 3 stages of multiple myeloma?

The stages of myeloma are:
  • Smoldering: Non-active disorder, no symptoms.
  • Stage 1: Early in the disease, no symptoms.
  • Stage 2: The cancer is progressing and causing multiple symptoms.
  • Stage 3: Cancer is in multiple parts of the body and a person will experience complex symptoms.

What is the most common type of myeloma?

The most common type of myeloma is IgG kappa. In IgG kappa myeloma, the myeloma cells produce an immunoglobulin made from two IgG heavy chains bound to two kappa light chains. About 15% of patients have light chain myeloma. In this type of myeloma, the myeloma cells secrete only light chain protein and no heavy chains.

What are the 8 types of multiple myeloma?

Types of Multiple Myeloma
  • Light Chain Myeloma.
  • Non-secretory Myeloma.
  • Solitary Plasmacytoma.
  • Extramedullary Plasmacytoma.
  • Monoclonal Gammopathy of Undetermined Significance (MGUS)
  • Smoldering Multiple Myeloma (SMM)
  • Immunoglobulin D (IgD) Myeloma.
  • Immunoglobulin E (IgE) Myeloma.

Which is worse kappa or lambda myeloma?

About one in five people with multiple myeloma produce only light chains. Patients with lambda light chain disease have a three times worse prognosis than kappa light chain disease.

What is the difference between multiple myeloma and myeloma?

Multiple myeloma cells are abnormal plasma cells (a type of white blood cell) that build up in the bone marrow and form tumors in many bones of the body. Myeloma, also called multiple myeloma, is a cancer of the plasma cells. Plasma cells are white blood cells that make antibodies that protect us from infection.

How many stages are in multiple myeloma?

For multiple myeloma there are 3 stages. Often the stages 1 to 3 are written as the Roman numerals I, II and III. Generally, the higher the stage number, the larger the amount of the myeloma in the body. Talk to your doctor if you have questions about staging.

What is the most definitive test to confirm a diagnosis of multiple myeloma?

Bone marrow biopsy

People with multiple myeloma have too many plasma cells in their bone marrow. The procedure used to check the bone marrow is called a bone marrow biopsy and aspiration. It can be done either at the doctor’s office or at the hospital.

What’s the difference between myeloma and multiple myeloma?

Multiple myeloma cells are abnormal plasma cells (a type of white blood cell) that build up in the bone marrow and form tumors in many bones of the body. Myeloma, also called multiple myeloma, is a cancer of the plasma cells. Plasma cells are white blood cells that make antibodies that protect us from infection.

What is usually the first symptom of multiple myeloma?

Multiple myeloma causes many symptoms, but bone pain often is the first symptom people notice. Other symptoms include: Weakness in your arms and legs and/or a sensation of numbness in your arms and legs. Multiple myeloma can affect the bones in your spine, causing them to collapse and press on your spinal cord.

Is light chain myeloma worse?

LCMM has a worse prognosis than other more common MM types, so a rapid diagnosis and early treatment are vital for improving patient outcomes.

What is the final stage of myeloma?

In multiple myeloma cases, stage 3 is the terminal stage. This means it’s the most advanced stage of this type of rare cancer. Doctors use the international staging system to determine the stage of the cancer. This system is based on the levels of serum beta-2 microglobulin and serum albumin.

Can you live a normal life with myeloma?

Apart from ongoing monitoring, most myeloma patients are able to live fairly normal lives, with few restrictions on low-impact exercise and other activity.

How fast does myeloma progress?

The risk of myeloma progressing is highest in the first 5 years after diagnosis. About 50 out of 100 people (50%) with smouldering myeloma develop symptoms and need treatment within the first 5 years. However, after 5 years the risk decreases and some people never develop symptoms or need treatment.

What is the main cause of multiple myeloma?

The exact cause of multiple myeloma is not known. Symptoms occur as a result of a process that is initiated by the abnormal multiplication of plasma cells in bone marrow.

What foods should I avoid with multiple myeloma?

Since medications used to treat multiple myeloma often cause nausea and vomiting, avoid foods that are spicy and fried. Avoid foods with strong odors. Instead, choose foods that are at room temperature and bland such as crackers, cheese, canned fruit, yogurt, toast, potatoes, rice, and pasta. Choose protein-rich foods.

What’s the longest you can live with multiple myeloma?

Survival rates tell you what percentage of people with the same type and stage of cancer are still alive a certain amount of time (usually 5 years) after they were diagnosed.
