Multiple Myeloma cancer last stage symptoms(Jan 2024)

The disease is relatively uncommon, representing about 1.8% of all new cancer cases, and occurs predominantly in the geriatric population with a median age at diagnosis of about 70 years

Multiple Myeloma is a blood cancer that affects cells found in the bone marrow, specifically plasma cells, which are a key part of the body's immune system. It is characterized by the abnormal increase of monoclonal immunoglobulins, leading to specific end-organ damage. The disease is relatively uncommon, representing about 1.8% of all new cancer cases, and occurs predominantly in the geriatric population with a median age at diagnosis of about 70 years. There seems to be an increased incidence in African American and black populations by as much as twofold.The pathophysiology of multiple myeloma involves the unchecked production of plasma cells, which can ultimately lead to structural bone damage, weakened bones, and painful fractures or bone breaks over time. The disease can also cause anemia, kidney problems, and infections due to the lowering of the body's ability to fight infections.

Symptoms 

Multiple myeloma can present a variety of symptoms, including:

• Bone Pain: Often in the back, ribs, or hips, it is a persistent dull ache.
• Weakness and Fatigue: Caused by anemia, resulting in tiredness, weakness, and shortness of breath.
• Kidney Problems: May lead to symptoms such as swollen ankles, fatigue, and shortness of breath.
• Infections: Weakened immune system can cause frequent and persistent infections.
• Bleeding and Bruising: Such as nosebleeds, bleeding gums, and heavy periods.
• High Calcium Levels: Can lead to symptoms like extreme thirst, stomach pain, and frequent urination.
• Other Symptoms: These may include nausea, constipation, loss of appetite, and mental fogginess or confusion

Causes

The exact cause of multiple myeloma is not fully understood, but several factors have been identified as potential contributors to the development of the disease. These include:

• Genetic Mutations: Although the genetic mutations that cause myeloma are acquired and not inherited, family history is a known risk factor for multiple myeloma. First-degree relatives of people with multiple myeloma have a 2 to 4 times higher risk of developing the disease.
• Environmental Factors: Exposure to certain types of industrial and agricultural chemicals, high doses of radiation, and viruses have been linked to an increased risk of myeloma.
• Age and Race: Myeloma occurs most commonly in people over 60, and it is slightly more common in men than women. It also occurs twice as frequently in Black people than in White people.
• Monoclonal Gammopathy of Undetermined Significance (MGUS): Some people develop myeloma after having been diagnosed with MGUS, a condition where there is an excess of protein molecules in the blood. Every year, around 1 in every 100 people with MGUS go on to develop multiple myeloma.

Diagnosis of Multiple myeloma

Multiple myeloma can be difficult to diagnose in the early stages due to its few or no symptoms. The diagnosis typically involves a series of tests and examinations. When myeloma is suspected, a patient is usually referred to a hematologist for further evaluation. The following are the main steps involved in the diagnosis of multiple myeloma:

1. Medical History and Physical Examination: A general practitioner will examine the patient, ask about symptoms, medical history, and overall health. They will look for signs such as bleeding, infections, and bone tenderness.
2. Blood and Urine Tests: These play a key role in diagnosing myeloma. They are used to check for certain antibodies, proteins, and the presence of M protein, which is a strong indicator of myeloma. Other blood tests measure the levels of different cells in the blood.
3. Imaging Tests: CT scans, MRI scans, X-rays, or PET scans may be performed to look for any bone damage or related problems.
4. Bone Marrow Biopsy: A bone marrow biopsy is usually needed to confirm the diagnosis. A small sample of bone marrow is taken, typically from the hip bone, and examined for cancerous plasma cells.

Treatments for multiple myeloma

The main treatments for multiple myeloma include chemotherapy, targeted cancer drugs, steroids, and supportive treatments to prevent or control problems caused by the disease. The specific treatment plan depends on the results of blood tests, bone marrow tests, or scans. Some people may not need immediate treatment and are closely monitored through a strategy called "watch and wait." When treatment is necessary, it often involves a combination of targeted drugs, chemotherapy, and steroids. 

Additionally, supportive treatments such as radiotherapy, surgery, and high-dose chemotherapy with a stem cell transplant may be recommended for eligible patients. The goal of treatment is to control the myeloma, and when there is no sign of active myeloma in the body, it is said to be in remission. However, it's important to note that most cases of multiple myeloma cannot be cured, and additional treatment is usually needed when the cancer comes back. Research on new treatments, including clinical trials, is ongoing to improve outcomes for people with multiple myeloma.

Side effects of multiple myeloma

The side effects of multiple myeloma treatment can vary depending on the specific drugs used. Common side effects may include:

• Gastrointestinal Issues: Constipation, diarrhea, nausea, and vomiting.
• Fatigue: Feeling very tired is a common side effect of treatment.
• Neuropathy: Some myeloma drugs can cause tingling, numbness, or pain in the hands and feet.
• Anemia: Chemotherapy drugs for myeloma may harm red blood cells, leading to anemia.
• Infections: Some treatments can weaken the immune system, increasing the risk of infections.
• Mouth Sores: These can occur as a side effect of treatment.
• Hair Loss: Some treatments may cause hair loss.
• Low Blood Counts: This can lead to anemia and easy bruising.

Success rate

The success rate of bone marrow transplant for multiple myeloma depends on several factors, including the patient's age, overall health, and the stage of the disease. According to a study, the 3-year overall survival rate after autologous hematopoietic stem cell transplantation (ASCT) for multiple myeloma was 76.7%. Another study reported that the 10-year overall survival rate after stem cell transplantation was around 80% for patients who survived the first 2 to 5 years after the transplant. 

However, it's important to note that ASCT is associated with risks, including a 3-5% mortality rate. Additionally, stem cell transplant is a very intensive treatment that can cause severe side effects, and it is not suitable for everyone. The success rate of bone marrow transplant for multiple myeloma varies from patient to patient, and it's essential to discuss the potential benefits and risks of the procedure with a healthcare professional.

Conclusion

Multiple myeloma is a type of blood cancer that affects plasma cells in the bone marrow. It can cause a range of symptoms, including bone pain, weakness, fatigue, kidney problems, infections, and bleeding. The exact cause of multiple myeloma is not fully understood, but several factors, including genetic mutations, environmental factors, and age, have been identified as potential contributors. 

The diagnosis of multiple myeloma involves a series of tests and examinations, including blood and urine tests, imaging tests, and bone marrow biopsy. Treatment options for multiple myeloma include chemotherapy, targeted cancer drugs, steroids, and supportive treatments. Stem cell transplant may also be recommended for eligible patients. 

While the success rate of bone marrow transplant for multiple myeloma varies from patient to patient, it can be an effective treatment option for some people. Ongoing research is focused on improving outcomes for people with multiple myeloma. If you experience any symptoms of multiple myeloma, it's essential to consult a healthcare professional for proper evaluation and diagnosis.
