Whether you’re seeking knowledge for yourself or a loved one, this guide is here to help you navigate the journey with confidence.
Facts about Bone Marrow Cancer:
FACT 1. What are the Bone Marrow Cancers?
Bone marrow cancer is not a single disease but rather a collective term that refers to a group of malignancies that originate in the Bone Marrow, spongy tissue inside your bones, such as the hip and sternum. Your marrow serves as the body’s primary site for the development of all types of blood cells; failure in the production of these cells can lead to certain conditions, such as leukemia, Multiple myeloma, and Myelofibrosis.
This cancer fundamentally disrupts the functioning of healthy cells, resulting in a wide range of systemic effects throughout the body. A precise Understanding of these terms is crucial for better recovery as well as diagnosis, which is required to detect the condition in its early stages. Along with a comprehensive diagnostic approach, advanced treatment modalities can help increase the survival rate.
FACT 2. What are the different types of Bone Marrow Cancer?
Bone Marrow Cancer is not a single disease but rather comprises different types of malignancies, all characterized by their cellular origins, growth patterns, and clinical implications. The most commonly diagnosed cancers are leukemia, lymphoma, and multiple myeloma. Other types include Myeloproliferative Neoplasm (MPN) and Myelodysplastic Syndrome (MDS). Here are some of the types given below:
Leukemia- Leukemia typically originates in the bone marrow, most commonly affecting the white blood cells. Leukemia cells divide uncontrollably, impacting the growth of the healthy cells and severely impairing the body’s ability to fight infections.
Leukemia is further divided by its growth (acute or chronic) and white blood cell types (lymphoid, myeloid)
- Acute Myeloid Leukemia- An Aggressive form of tumor that typically affects people over 65. It involves a large number of immature, dysfunctional myeloid cells called myeloblasts that require immediate, aggressive treatment.
- Acute Lymphoid Leukemia—The most common type of leukemia in children (childhood leukemia) involves rapid production of lymphoid cells, which affects the immune system and overall health.
- Chronic Myeloid Lymphoma- A slow-growing leukemia of adults (adult lymphoma) characterized by overproduction of Myeloid cells, does not show any significant symptoms.
- Chronic Lymphocytic Lymphoma- Most commonly occurs in adults with no symptoms in the early stage and involves the accumulation of abnormal lymphocytes. Due to its slow progression, it may lead to a severe condition that requires immediate treatment.
Multiple Myeloma: This type of cancer occurs in the plasma cells that produce antibodies to fight infection. Cancerous plasma cells divide and accumulate, crowding out the healthy cells and producing abnormal protein (monoclonal or M protein) that affects various organs such as the kidney, weakening the bones (making them fragile), and increasing the risk of fractures.
Myeloproliferative Neoplasms (MPNs): Bone marrow produces an excessive number of one or more types of blood cells (red blood cells, white blood cells, or platelets). Types include
- Myelofibrosis (Primary Myelofibrosis): A particular kind of MPN impairs the formation of healthy blood cells and leaves scars in the bone marrow. The spleen may grow as a result of scarring, as other organs try to make up for the loss of blood cells. Some other MPNs include Essential Thrombocythemia and Polycythemia Vera.
- Myelodysplastic Syndromes (MDS): These are a class of blood disorders in which the bone marrow’s blood-forming cells develop abnormalities (dysplastic), resulting in a lack of healthy new blood cells. MDS is classified as a form of cancer and can develop into acute myeloid leukemia (AML), a malignancy that grows more quickly, in about one-third of cases.
- Lymphoma: Originates in the Lymph nodes, a part of the immune system. Lymphoma is classified as a blood cancer since it grows from lymphocytes (white blood cells) that start in the bone marrow. It is regarded as one of the three forms of blood cancer that are diagnosed the most frequently. Types include Hodgkin Lymphoma and Non-Hodgkin Lymphoma.
| Cancer Type | Primary Affected Cell Type | Key Characteristic/Impact on Bone Marrow | Typical Growth Rate | Brief Description |
| Leukemia | Myeloid or Lymphoid cells | Overproduction of immature or abnormal white blood cells, crowding out healthy cells | Acute (fast) or Chronic (slow) | Cancers originating in blood-forming cells, typically white blood cells, impair immunity and blood clotting. |
| Multiple Myeloma | Plasma cells | Accumulation of cancerous plasma cells, producing abnormal antibodies (M proteins) and causing bone damage | Variable | Cancer of antibody-producing plasma cells, leading to bone weakness, kidney problems, and immune dysfunction. |
| Myelofibrosis | Blood stem cells (myeloid lineage) | Scarring in the bone marrow, impeding healthy blood cell production, often leads to an enlarged spleen. | Chronic (slow) | A myeloproliferative neoplasm causing bone marrow scarring and inefficient blood cell formation. |
| Myelodysplastic Syndromes (MDS) | Blood-forming cells | Abnormal (dysplastic) blood-forming cells leading to insufficient healthy blood cell production; can progress to AML. | Variable; often slow, but can transform acutely | A group of disorders where the bone marrow doesn’t make enough healthy blood cells; considered a type of cancer. |
| Lymphoma | Lymphocytes | Develops from lymphocytes, primarily affecting the lymphatic system but originating in the bone marrow | Variable (Hodgkin vs. Non-Hodgkin) | Cancer of lymphocytes, part of the immune system, often presents with swollen lymph nodes. |
Fact 3. Recognizing the Symptoms
Symptoms of Bone marrow Cancers are generally nonspecific and arise during the early stages. Symptoms may vary due to the inability of the body to produce blood cells, as well as due to the accumulation of abnormal cells. The wide array of symptoms ranges from nonspecific to specific, depending on the type and condition. Some of the symptoms are
Non-Specific Symptoms-
Can appear in any type of Blood Cancer
- Persistent Fatigue and Weakness (due to anemia)
- Unexplained Fever or Chills( low immune cell count)
- Heavy Night Sweats
- Unexplained Weight Loss
Symptoms from Low Blood Counts (Cytopenias)
Cancerous cells can crowd out healthy blood cell production in the bone marrow.
- Anemia (low red blood cells) leads to profound fatigue.
- Shortness of breath
- Weakened immune system (due to low functional white blood cells)
- Thrombocytopenia (low platelets)
- Unexplained bleeding
- Tiny red spots under the skin (petechiae).
Symptoms from Bone Involvement (Multiple Myeloma):
Myeloma cells can directly damage bone tissue, producing symptoms such as
- Bone Pain
- Bone Weakness
- Easily Broken Bones (Fractures)
- Spinal Cord Compression
Other Systemic Symptoms
- Enlarged Spleen or Liver
- Hypercalcemia (due to excessive calcium in the bloodstream)
Nervous System Issues:
- Mental Fogginess or Confusion (Due to hypercalcemia or hyperviscosity)
- Peripheral damage due to abnormal proteins produced by myeloma cells
- Hyperviscosity (Thickened Blood)
- Tissue Growths (in Myelofibrosis)
- Kidney Problems
Fact 4. Causes and Risk Factors
What are the causes of Bone marrow Cancer?
While the exact cause is still unclear, it is believed that the change in the DNA (mutation) in the stem cells or plasma cells within the bone marrow disrupts the cell cycle division and growth, leading to uncontrolled growth of these cells. In the majority of cases, the mutation is acquired during a lifetime and is generally not inherited. These acquired mutations suggest that external factors or cellular errors play a significant role.
What are the risk Factors associated with Bone marrow Cancer?
Some of the risk factors (reversible or irreversible) that can increase the risk of this type of cancer include:
- Age: Increased age is a significant risk factor for certain bone marrow cancers affecting people in their 50s (myelofibrosis) and 60s (multiple myeloma). Acute myeloid leukemia (AML) is prevalent in adults aged 65 or older, while Acute Lymphocytic leukemia is common among children and can also affect adults.
- Gender: Men have higher chances of getting Myeloma, AML, and ALL.
- Race: Multiple myeloma is more frequent in Black people than in White and Asian populations. On the other hand, white people are more prone to develop CLL. These specific discrepancies suggest underlying genetic or environmental connections that require further research.
- Family History: Close Blood relatives with Multiple myeloma or CLL can increase the risk of these cancer types.
- Smoking: It contains Tobacco and nicotine, benzene, and other cancer-causing agents that can increase the risk of myeloma and certain lymphomas.
- Chemical: exposure to certain chemicals, such as Benzene, agrochemicals like insecticides and herbicides, is linked with increased risk of myeloma and certain lymphomas.
- Radiation: High-dose radiation from the nuclear plant or prior exposure to radiation during therapy can increase the risk of myeloma and AML.
- Genetic Factor: Genetic conditions such as Down syndrome can increase the risk of myeloma as well as AML.
Fact 5: Diagnostic Approaches
How to Diagnose Bone Marrow Cancer?
Early diagnosis is not easy, as it shows non-specific symptoms at early stages. Your provider may start your initial assessment by knowing your medical history and physical examination by checking certain signs such as lymph nodes, spleen, liver, and they will also suggest some blood tests to diagnose the condition, such as
- Complete Blood Count (CBC) test: This test checks for the complete red blood cells, such as RBCs, platelets, and abnormal levels of RBCs in blood (Anemia). Low levels of platelets (Thrombocytopenia) often indicate leukemia or multiple myeloma.
- Peripheral Blood smear test: Microscopic examination of the cells for abnormalities.
- Blood protein Test: This test analyzes the various proteins in the blood or detects the Abnormal level of Immunoglobulin, specifically the M protein released by cancerous plasma cells.
- Blood Chemistry test: Checks for certain electrolytes such as calcium, potassium, and sodium, and kidney function.
- Flow Cytometry (Immunohistochemistry): These tests check for certain protein markers on the cell surfaces to identify the leukemias.
- Circulating Tumor Cell Test: These advanced tests check for the DNA material or its fragments in the bloodstream, help monitor treatment effectiveness, and help understand the genetic characteristics of the cancer.
Imaging test
If not confirmed through Diagnosis, imaging tests can help to confirm the diagnosis and Screening.
- X-ray: Can reveal bone damage due to multiple myeloma.
- MRI: It uses a strong magnetic field and radio waves to produce highly detailed images, especially valuable for examining bones and bone marrow for subtle changes
- CT scan: Uses X-ray to produce a highly enhanced 3d image of the affected region, useful for showing bone damage, enlarged organs (like the spleen or Liver) for tumors.
- PET scan: Often combined with a CT scan, it uses a radioactive substance to analyse the area of high metabolic activity (often related to cancer)
Other tests
Lumbar Puncture (Spinal Tap): In this test, the cerebrospinal fluid surrounding the brain and spinal cord is collected to check for the spread in the nervous system.
FACT 6. Treatment Modalities
The Treatment is highly individualized depending upon the patient’s condition, cancer type, and stage. Here are some of the treatment options that can help treat bone marrow cancer in a much more effective way.
What are the treatment options for Bone Marrow Cancer?
- Chemotherapy: It uses powerful anticancer drugs to kill the rapidly dividing cancerous cells, often involving a combination of different drugs and administered in cycles.
- Radiotherapy: It utilizes high-dose radiation to slow down the growth of cancer cells. It can be given either to a specific region of the body (localized radiation) where there is a collection of leukemia cells (in the spleen or liver) or to the entire body(Total Body Irradiation) to destroy any remaining cells.
- Biological Therapy: It uses growth factors, interleukins, or monoclonal antibodies to restore the body’s natural defenses or to target specific biological processes necessary for cancer survival.
- Targeted therapy: It uses the checkpoint inhibitors to target the specific protein antigen on the cancer cells to slow down their growth
- Immunotherapy: It is an advanced cancer treatment technique that educates the patient’s immune cells to target the cancer cells effectively. Some of its types, such as Dendritic cell-based Immunotherapy and CAR-T cell therapy, are being used to target a certain type of leukemia.
- Surgery (Splenectomy): It is the surgical procedure that removes the spleen when it becomes enlarged due to chronic leukemias or if it hinders the effectiveness of chemotherapy.
- STEM cell Transplantation: also known as bone marrow transplantation, uses healthy STEM cells either from the patient or a donor, and it is the potentially curative treatment for most cancers, such as leukemia, lymphoma, and myeloma.
Types are:
- Autologous STEM cell transplant—uses the patient’s stem cells. This approach minimizes the risk of host rejection and is used for conditions like lymphoma and myeloma.
- Allogeneic STEM cell transplant: Uses STEM cells from a compatible donor (either from a first-degree relative or Umbilical cord stem cells). But it also comes with the risk of Graft vs host disease (GVHD), where it can attack the patient’s healthy cells. An advantage comes with the Graft vs Cancer effect, where donor immune cells target the cancer cells of the receiver more effectively.
Fact 7. Prognosis and Survival
Anyone can get bone marrow cancer, but by knowing the prognosis (outlook) of the disease, and with the advancement in diagnosis and treatment, there is an increased chance of a cure from this disease as well as survival. Many factors can affect the prognosis of this disease; these are
Cancer Type: The specific types of bone cancer, such as leukemia, lymphoma, and myeloma, have their survival rates.
Age: Diagnosis varies accordingly with age; usually, younger individuals have higher survival rates due to their strong immune systems and tolerance to a variety of treatments like chemo/radiotherapy. Older adults are more prone to risk due to their overall health and limited tolerance.
Disease stage: For malignancies such as lymphoma, the disease stage (localized vs. progressed) has significant effects on prognosis. Important markers for leukemias include the percentage of immature blast cells in the bone marrow, the initial blood cell counts at diagnosis, and the progression of cancer cells to the central nervous system (brain or spinal cord).
Genetic mutation: Specific genetic changes (mutations) within cancer cells are frequently the strongest indicators of outcome. For instance, the prognosis can be greatly impacted by the presence of the PML: RARA gene in AML or the Philadelphia chromosome in ALL. Germinal Center B-Cell (GCB) versus Activated B-Cell (ABC) in Diffuse Large B-Cell Lymphoma (DLBCL) is an example of a molecular subtype that might influence how the disease acts and reacts to therapy.
Overall health: Patients’ general health and other health conditions, such as diabetes, heart disease, or lung disorders, can affect patients’ ability to tolerate a range of treatments.
Treatment response: The effectiveness of a treatment is often determined by the speed and completeness of a patient’s reaction to initial treatment, including the time it takes for the cancer to go into remission. The prognosis is adversely affected if the cancer returns after remission.
