Lymphoma, Myeloma & Leukemia
Introduction :
Lymphoma
“Lymphoma” is the general term for cancer in your lymphatic system — the network of tissues, vessels and organs that help your body fight infection. It’s considered a blood cancer because the condition starts in white blood cells (lymphocytes) in your lymphatic system.
There are two main lymphoma categories — Hodgkin lymphoma and non-Hodgkin lymphoma — and more than 70 lymphoma subtypes. Lymphomas can be aggressive (fast-growing) or indolent (slow-growing).
Multiple Myeloma
Multiple myeloma is a rare blood cancer that affects your plasma cells. Plasma cells are white blood cells and part of your immune system. Plasma cells (sometimes called B-cells) make antibodies. These antibodies, called immunoglobulins, help fight infection.
Multiple myeloma happens when healthy cells turn into abnormal cells that multiply and produce abnormal antibodies called M proteins. This change starts a cascade of medical issues and conditions that can affect your bones, your kidneys and your body’s ability to make healthy white and red blood cells and platelets.
Leukemia
Leukemia is a cancer of the blood, characterized by the rapid growth of abnormal blood cells. This uncontrolled growth takes place in your bone marrow, where most of your body’s blood is made. Leukemia cells are usually immature (still developing) white blood cells. The term leukemia comes from the Greek words for “white” (leukos) and “blood” (haima).
Lymphoma
Many lymphoma symptoms are like symptoms of other, less serious diseases. Having these symptoms doesn’t mean that you have lymphoma. But you should consider talking to a healthcare provider whenever you have changes in your body that don’t go away within a few weeks.
Symptoms common to Hodgkin lymphoma and non-Hodgkin lymphoma can include:
- Painless swelling of one or more lymph nodes in your neck, armpits or groin that doesn’t go away within a few weeks.
- Persistent fatigue, when you feel very tired day after day even after getting enough sleep.
- Fever stays above 103 degrees Fahrenheit (39.5 degrees Celsius) for more than two days, or a fever that comes back.
- Drenching night sweats, sweating that are so intense that you wake up to find your pajamas and sheets soaking wet.
- Shortness of breath (dyspnea), when you feel as if you can’t get enough air in your lungs.
- Unexplained weight loss, when you’ve lost 10% of your total body weight over six months without dieting or exercise.
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.
- Having fatigue — feeling so tired you can’t manage daily activities — and feeling weak. These are signs of anemia.
- Nausea and vomiting. This may be a sign of hypercalcemia.
- Not having an appetite and/or feeling thirstier than usual. These may be signs of hypercalcemia.
- Unexplained weight loss.
- Unexplained fever. This may be a symptom of a bacterial infection.
- Bruising or bleeding more easily. This may be a sign abnormal plasma cells prevent your body from producing enough platelets. Platelets help your blood to clot.
- Feeling confused or “foggy.”
Here are some of the conditions linked to multiple myeloma and their causes:
- Anemia: You don’t have enough red blood cells because multiplying abnormal plasma cells don’t leave room for your red blood cells.
- Bacterial infection, particularly pneumonia: Like red blood cells, abnormal plasma cells are multiplying and crowding healthy white blood cells that fight infection.
- Thrombocytopenia: You don’t have enough platelets — the cells that help your blood to clot — because abnormal plasma cells crowd out those platelets and keep your bone marrow from making enough platelets.
- Bone pain/bone fracture: Bone pain and/or fracture can happen if abnormal plasma cells destroy bone tissue, causing a soft spot in your bone. These are osteolytic lesions.
- Kidney problems/failure: Your kidneys filter waste and toxins. Abnormal plasma cells make M proteins that block the filtering process and damage your kidneys.
- Amyloidosis: This disease happens when abnormal proteins (amyloid proteins) build up in your organs.
- Hypercalcemia: This condition happens when damaged or weakened bones release too much calcium into your bloodstream.
- Hyperviscosity syndrome: M proteins — proteins made by abnormal plasma cells — thicken your blood. Your heart has to work harder to pump blood through your body.
- Cryoglobulinemia: Multiple myeloma can make proteins in your blood clump together when it’s cold.
Leukemia
Symptoms depend, in part, on the type of leukemia. For instance, if you have a chronic form of leukemia, you may not have noticeable symptoms in the early stages.
Common signs and symptoms of leukemia include:
- Fatigue, tiring easily.
- Fever or night sweats.
- Frequent infections.
- Shortness of breath.
- Pale skin.
- Unexplained weight loss.
- Bone/joint pain or tenderness.
- Pain or full feeling under your ribs on the left side.
- Swollen lymph nodes in your neck, underarm, groin or stomach, an enlarged spleen or liver.
- Bruising and bleeding easily, including nosebleeds, bleeding gums, a rash that looks like tiny red spots in skin (petechiae) or purplish/darkened skin patches.
Lymphoma
Lymphoma happens when the white blood cells in your lymphatic system change (mutate) into rapidly growing cancer cells that don’t die. Like most cancers, the majority of the genetic mutations that cause lymphoma happen spontaneously, without an identifiable cause. But research suggests the following conditions or issues may increase your risk of developing lymphoma:
- You have or have had viruses including HIV (human immunodeficiency virus), Epstein-Barr (mononucleosis) and Kaposi sarcoma human immunodeficiency virus.
- You have a family history of lymphoma.
- Your immune system is weakened by other conditions or medical treatments. For example, people who have organ transplants take immunosuppressant medication to keep their bodies from rejecting the transplanted organ.
- You have an autoimmune disease. An autoimmune disease happens when your immune system accidentally attacks your body instead of protecting it.
Multiple Myeloma
Healthcare providers and researchers aren’t sure what causes multiple myeloma. Some potential causes they’re exploring include:
- Genetic mutations: Researchers are investigating links between mutating or changing oncogenes (cells that promote growth) and multiple myeloma. They’ve also found most people who have multiple myeloma don’t have all pieces of a certain chromosome.
- Environmental factors: Some studies show potential connections between multiple myeloma and exposure to radiation or chemicals in pesticides, fertilizer or Agent Orange.
- Having an inflammatory disease or condition: Examples of inflammatory disease include heart disease, Type 2 diabetes and rheumatoid arthritis.
- Having obesity: This is having high levels of body fat.
Leukemia
Leukemia starts when the DNA of a single cell in your bone marrow changes (mutates). DNA is the “instruction code” that tells a cell when to grow, how to develop and when to die. Because of the mutation, or coding error, leukemia cells keep multiplying. All cells arising from the original mutated cell also have the mutated DNA.
Scientists don’t know what causes these developing cells to mutate. They’ve been able to identify some common mutations that people diagnosed with different types of leukemia share.
Lymphoma
Healthcare providers diagnose lymphoma by doing physical examinations to evaluate potential lymphoma symptoms and biopsies to obtain tissue for examination by a medical pathologist. If laboratory tests show signs of lymphoma, providers may do certain blood and imaging tests to learn more about your condition and to plan treatment.
Blood tests
- Complete blood count (CBC) with differential to analyze different types of white blood cells.
- Erythrocyte sedimentation rate (ESR) to detect inflammation that may be a sign of lymphoma.
- Lactate dehydrogenase (LDH) to detect large amount of cell “turnover” or growth/death.
- Liver and kidney function tests.
- Serum protein electrophoresis (SPEP) to evaluate monoclonal proteins (M proteins), which are abnormal proteins that your plasma cells produce.
Imaging tests
- Computed tomography (CT) scan to look for lymphoma signs such as enlarged lymph nodes, spleen or other organs.
- Positron emissions tomography (PET) scans to detect signs of cancer. PET scans are usually combined with low-resolution CT scans and are sometimes used in addition to magnetic resonance imaging (MRI) scans.
If you have non-Hodgkin lymphoma, your provider may order laboratory tests to identify genes, proteins and other substances that are unique to specific non-Hodgkin lymphomas.
Multiple Myeloma
Healthcare providers diagnose multiple myeloma by doing a physical examination, asking about your symptoms and asking about your family medical history.
Healthcare providers may do blood tests, imaging tests and urine tests to confirm you have multiple myeloma and, if you do, whether your disease is in early or late stages. Here’s information on specific tests:
- Complete blood count (CBC): This test measures your red and white blood cell numbers, the amount of hemoglobin in your red blood cells and your red blood cell concentration level.
- Blood chemistry test: This test shows your creatine levels (how well your kidneys work), albumin levels (this is a protein), calcium levels and lactic dehydrogenase levels (LDH). LDH is a tumor marker. A tumor marker is a substance in cancerous cells or healthy cells responding to cancer.
- Quantitative immunoglobulin test: This blood test measures the levels of certain antibodies in your blood.
- Electrophoresis: This test looks for M proteins in your blood.
- Urine tests: Healthcare providers may ask you to collect your urine at home over a 24-hour period so they can test for Bence Jones protein, another sign of multiple myeloma.
- X-rays: Healthcare providers use X-rays to look for bones damaged by multiple myeloma.
- Computed tomography (CT) scan: This is another way to look for bone damage.
- Magnetic resonance imaging (MRI): This test uses radio waves and strong magnets to create detailed images of your bones and spine. Healthcare providers may use this test to look for plasmacytomas. These are single groups of abnormal plasma cells.
- Positron emission tomography (PET) scan: This is another test for plasmacytomas.
- Bone marrow biopsies: Healthcare providers may do bone marrow biopsies to analyze the percentage of normal and abnormal plasma cells in your bone marrow. They may also test your bone marrow sample for changes in your DNA that may drive cancer growth.
Leukemia
Results from routine blood work can alert your healthcare provider that you may have an acute or chronic form of leukemia that requires further testing. Or they may recommend a workup if you have leukemia symptoms.
Diagnostic exams and tests may include:
- Physical exam: Your healthcare provider will ask about your symptoms and feel for swollen lymph nodes and an enlarged spleen or liver. They may also inspect your gums for bleeding and swelling. They may look for a skin rash associated with leukemia that may appear red, purple or brown.
- Complete blood count (CBC): This blood test lets your healthcare provider know if you have abnormal levels of red blood cells, white blood cells and platelets. If you have leukemia, you’ll likely have higher than normal counts of white blood cells.
- Blood cell examination: Your healthcare provider may take additional blood samples to check for markers that indicate the presence of leukemia cells or a specific type of leukemia. Flow cytometry and peripheral blood smear are additional tests your healthcare provider may order.
- Bone marrow biopsy (bone marrow aspiration): Your healthcare provider may perform a biopsy if you have an abnormal white blood cell count. A long needle inserted into your bone marrow (usually in your pelvic bone) draws out fluid during the procedure. The fluid sample gets tested in a lab for leukemia cells. A bone marrow biopsy helps determine the percentage of abnormal cells in your bone marrow, confirming a leukemia diagnosis.
- Imaging and other tests: Your doctor may order a chest X-ray, CT scan, or magnetic resonance imaging (MRI) scan if symptoms indicate leukemia has affected your bones, organs or tissue. The leukemia cells don’t show up on imaging.
- Lumbar puncture (spinal tap): Your healthcare provider may test a sample of spinal fluid to see if leukemia has spread to the spinal fluid surrounding your brain and spinal cord.
Lymphoma
Treatments vary based on lymphoma type. For example, if you have a slow-growing lymphoma, your healthcare provider may recommend active surveillance (watchful waiting) before starting treatment. In active surveillance, providers carefully monitor your overall health and signs of lymphoma.
Common lymphoma treatments include:
- Chemotherapy.
- Radiation therapy.
- Targeted therapy
- Immunotherapy.
- CAR T-cell therapy.
- Stem cell (bone marrow) transplantation.
Multiple Myeloma
Healthcare providers treat multiple myeloma based on your symptoms and the extent of your disease. For example, people who have MGUS usually don’t need treatment, but their healthcare provider will closely monitor their overall health. They may also develop a treatment plan so they can move quickly if symptoms do develop.
Some treatments healthcare providers may use if you have symptoms caused by multiple myeloma include:
- Pain medications: People often have significant bone pain.
- Antibiotics: A weakened immune system can lead to more infections. Your doctor may prescribe antibiotics to clear up these infections.
- Steroids: High doses of steroids can kill cancer cells and reduce inflammation.
- Chemotherapy: Healthcare providers use chemotherapy to reduce the number of abnormal plasma cells.
- Immunotherapy: This treatment stimulates your immune system so it develops more cancer-fighting cells.
- Radiation therapy: This treatment kills cancer cells and reduces bone tumors.
- Stem cell transplants: Stem cells are specialized cells in your bone marrow or blood that can help produce healthy new plasma cells. Healthcare providers typically recommend autologous stem cell transplants. This treatment replaces damaged or unhealthy stem cells with healthy stem cells from your body. Rarely, you may receive healthy plasma stem cells from a donor. This is an allogenic stem cell transplant.
Leukemia
Treatments for leukemia depend on the type of leukemia you have, your age and overall health, and if the leukemia has spread to other organs or tissues.
Common treatments often include a combination of the following:
- Chemotherapy: Chemotherapy is the most common form of leukemia treatment. It involves using chemicals to kill leukemia cells or keep them from multiplying. During treatment, you may receive the chemicals (medication) as a pill, an injection into a vein or a shot under your skin. Usually, you’ll receive a combination of chemotherapy drugs.
- Immunotherapy (biologic therapy): This treatment uses certain drugs to boost your body’s defense system — your immune system — to fight leukemia. Immunotherapy helps your immune system identify cancer cells and produce more immune cells to fight them.
- Targeted therapy: This treatment uses drugs designed to attack specific parts of a leukemia cell (like a protein or gene) that are causing them to overtake normal blood cells. Targeted therapies may prevent leukemia cells from multiplying, cut off the cells’ blood supply or kill them directly. Targeted therapy is less likely to harm normal cells. Examples of targeted therapy drugs include monoclonal antibodies and tyrosine kinase inhibitors.
- Radiation therapy: This treatment uses strong energy beams or X-rays to kill leukemia cells or stop them from growing. During treatment, a machine directs radiation to the exact spots in your body where the cancer cells are or distributes radiation over your whole body. Distributing radiation throughout your body may happen before a hematopoietic cell transplant.
- Hematopoietic cell transplant (stem cell or bone marrow transplant): This treatment replaces the cancerous blood-forming cells killed by chemotherapy and/or radiation therapy with new, healthy hematopoietic cells. Your healthcare provider may remove these healthy cells from your blood or bone marrow before chemo and radiation, or they may come from a donor. The healthy new cells multiply, forming new bone marrow and blood cells that become the red blood cells, white blood cells and platelets your body needs.
- Chimeric antigen receptor (CAR) T-cell therapy: This is a novel type of therapy that takes your body’s infection-fighting T-cells (T-cell or T-lymphocyte is a type of immune cell), engineers them to fight leukemia cells and infuse them back into your body.
