Multiple myeloma Treatment in Singapore

What is Multiple Myeloma?

Multiple myeloma is a rare blood malignancy that affects the plasma cells. Plasma cells are a type of white blood cell that plays a crucial role in your immune system. Plasma cells (also known as B-cells) produce antibodies. Immunoglobulins, also known as antibodies, play a crucial role in the body's defence against infections.

Multiple myeloma develops when healthy cells become abnormal and multiply, producing abnormal antibodies known as M proteins. This alteration triggers a chain reaction of medical problems and illnesses that can harm your bones, kidneys, and body's capacity to produce healthy white and red blood cells and platelets.

What is the Importance of Timely Treatment?

• Multiple myeloma should be treated timely to improve the outcome and quality of life. Early intervention slows disease progression and prevents consequences such as bone fractures, renal damage, and anaemia.
• It also enhances the chances of a more significant response to treatment, resulting in more profound and prolonged remission.
• Furthermore, treating the condition early can avoid organ damage, particularly in the kidneys, and considerably increase survival rates.
• Patients have a higher quality of life and fewer hospitalisations when symptoms like pain and exhaustion are managed early, so timely treatment is essential for the best results.

What are the Common Symptoms of Multiple myeloma?

Early in the development of multiple myeloma, there may be no symptoms. When signs and symptoms occur, they may include:

• Bone discomfort, particularly in the spine, chest, and hips.
• Nausea.
• Constipation.
• Loss of appetite.
• Mental fog or confusion.
• Tiredness.
• Infections.
• Weight loss.
• Weakness.
• Thirst.
• Urinate frequently.

Stages of Multiple Myeloma

Cancer staging provides the foundation for treatment. The staging approach for multiple myeloma begins by classifying the condition into one of four categories:

• MGUS: Blood tests reveal tiny quantities of M protein; around 1% to 2% of patients with MGUS develop multiple myeloma.
• Solitary or isolated plasmacytomas: Refer to single groupings of abnormal plasma cells.
• SMM: A pre-cancerous type of multiple myeloma. People with SMM may experience minor symptoms, as well as tests revealing small amounts of M protein in their blood and an increase in plasma cells in their bone marrow.
• Multiple myeloma: This classification indicates that tests reveal many abnormal plasma cells, elevated M protein levels in blood or urine, and a high percentage of abnormal plasma cells in bone marrow.

Causes, Risk Factors and Complications of Multiple Myeloma

Causes

Healthcare practitioners and researchers are unsure what causes multiple myeloma. Some probable causes they're looking into include:

• Genetic mutations: Researchers are investigating the relationship between modifying or changing oncogenes (cells that drive growth) and multiple myeloma. They also discovered that most people with multiple myeloma do not have all the pieces of a particular chromosome.
• Environmental factors: Some studies reveal potential links between multiple myeloma and exposure to radiation or chemicals in pesticides or fertilisers.
• Having an inflammatory disease or condition, such as heart disease, Type 2 diabetes, or rheumatoid arthritis.
• Obesity: It refers to having high quantities of body fat.

Risk Factors

The following factors may raise the risk of multiple myeloma:

• Growing older: The majority of patients are diagnosed in their late sixties.
• Being Male: Men are more prone to contract the condition than women.
• Have a family history of multiple myeloma: Having a brother or parent with numerous myeloma raises the chance of the disease.
• Having monoclonal gammopathy of unknown significance, or MGUS: Multiple myeloma begins with MGUS, doubling the risk.

Complications

The complications of multiple myeloma include:

• Infections: Having multiple myeloma reduces the body's ability to fight infections.
• Bone issues: Multiple myeloma can cause bone discomfort, weakening, and fractures.
• Kidney issues: Multiple myeloma can impair renal function. It can cause renal failure.
• Anaemia is characterised by a low number of red blood cells: Multiple myeloma cells squeeze out healthy blood cells, which can lead to anaemia and other blood disorders.

Latest Research and Technologies in the Treatment of Multiple Myeloma in Singapore

• In Singapore, recent advancements in multiple myeloma (MM) treatment include the approval of Johnson & Johnson's bispecific antibody targeting BCMA, enhancing the immune response against cancer cells. Additionally, IASO Bio's CAR-T therapy, Equecabtagene Autoleucel, is under regulatory review, offering a fully human approach to cellular therapy.
• Research from the Cancer Science Institute of Singapore has identified the ADAR1 gene as a key factor in lenalidomide resistance, suggesting new therapeutic targets for this condition. These developments signify significant progress in personalised MM treatment strategies.

Multiple Myeloma Prevention Tips

Some preventative tips for multiple myeloma:

• Regular health exams and blood testing allow for early detection.
• A healthy lifestyle includes eating a well-balanced diet, staying physically active, and avoiding smoking and excessive alcohol consumption.
• To lower the risk, manage chronic conditions such as obesity, diabetes, and hypertension.
• Toxic exposure should be kept to a minimum.
• If you have a family history of blood cancer, you should get regular check-ups and genetic counselling.

These strategies can help manage risk factors and encourage early detection.
