Blood Cancer and Its Treatment

 

What is Blood Cancer?

Blood cancer, also known as hematologic cancer, affects the production and function of blood cells. It typically begins in the bone marrow where blood is produced. Malignant blood cells disrupt the normal functioning of the blood, compromising the immune system and the body's ability to fight infections.

Types of Blood Cancer

  1. Leukemia: A group of cancers that begin in the bone marrow and lead to the overproduction of abnormal white blood cells. This excessive production interferes with the bone marrow's ability to produce red blood cells and platelets. Leukemia can be acute (fast-growing) or chronic (slow-growing), and is further classified into:
    • Acute Lymphoblastic Leukemia (ALL)
    • Acute Myeloid Leukemia (AML)
    • Chronic Lymphocytic Leukemia (CLL)
    • Chronic Myeloid Leukemia (CML)
  2. Lymphoma: Cancer that starts in the lymphatic system, which is a crucial part of the immune system. It primarily affects lymphocytes, a type of white blood cell. Lymphoma is categorized into:
    • Hodgkin Lymphoma (HL): Characterized by the presence of Reed-Sternberg cells.
    • Non-Hodgkin Lymphoma (NHL): A diverse group of blood cancers that include various subtypes, such as diffuse large B-cell lymphoma and follicular lymphoma.
  3. Myeloma: Also known as multiple myeloma, this cancer affects plasma cells in the bone marrow. Abnormal plasma cells multiply uncontrollably and produce defective antibodies, leading to weakened bones, anemia, kidney dysfunction, and increased susceptibility to infections.

 Causes of Blood Cancer

·       Genetic mutations

  • Exposure to radiation or harmful chemicals
  • Family history of blood cancer
  • Weakened immune system
  • Certain infections like Epstein-Barr virus (EBV)

 

Symptoms and Diagnosis

Early Signs of Blood Cancer

  • Persistent fatigue
  • Frequent infections
  • Unexplained weight loss
  • Easy bruising or bleeding
  • Swollen lymph nodes

Importance of Timely Diagnosis

Early detection significantly improves treatment outcomes and survival rates.

Diagnostic Procedures

  • Blood Tests: Identify abnormal blood cell counts.
  • Bone Marrow Biopsy: Examines bone marrow for cancerous cells.
  • Imaging Tests: MRI, CT scans, and PET scans help assess the spread.
  • Genetic Testing: Detects specific mutations aiding in targeted therapy.

Treatment Options for Blood Cancer

Chemotherapy

Uses powerful drugs to kill rapidly dividing cancer cells. It's often a first-line treatment.

Radiation Therapy

Employs high-energy rays to target and destroy cancer cells, typically used for localized lymphoma.

Immunotherapy

Enhances the body's immune system to detect and fight cancer cells.

Targeted Therapy

Involves drugs that specifically attack cancer cells with certain genetic mutations, sparing healthy cells.

 

 

General Cost of Blood Cancer Treatment

  1. Chemotherapy:
    • The cost of chemotherapy for blood cancer typically ranges from ₹50,000 to ₹3,00,000 per cycle, depending on the type of cancer, the drugs prescribed, and the number of cycles needed. For patients who require multiple rounds of chemotherapy, this cost can accumulate over time.
  2. Bone Marrow Transplant:
    • Autologous Transplant: The cost for an autologous bone marrow transplant (using the patient's own stem cells) can range between ₹8,00,000 to ₹15,00,000, depending on the hospital and the complexity of the procedure.
    • Allogeneic Transplant: An allogeneic transplant (using a donor's stem cells) is more expensive due to the need for donor matching, additional medical support, and longer recovery time. The cost for this type of transplant can range from ₹15,00,000 to ₹30,00,000 or more.
    • Haploidentical and Umbilical Cord Blood Transplant: These newer forms of transplant may cost slightly more, ranging from ₹15,00,000 to ₹25,00,000, depending on the hospital and treatment requirements.
  3. Radiation Therapy:
    • Radiation therapy for blood cancers like lymphoma can cost between ₹1,00,000 and ₹5,00,000, depending on the number of sessions required and the type of radiation therapy prescribed.
  4. Immunotherapy and Targeted Therapy:
    • Immunotherapy and targeted therapy are newer and more advanced treatment options. The cost for these treatments can be relatively high, ranging from ₹1,50,000 to ₹5,00,000 per cycle, and patients may need multiple cycles for effective results. These therapies are often used in advanced stages of blood cancer or when other treatments are not as effective

Bone Marrow Transplant

Bone marrow transplant (BMT) is a medical procedure used to replace damaged or destroyed bone marrow with healthy stem cells. It is critical for treating blood cancers like leukemia, lymphoma, and multiple myeloma.

  • Autologous Transplant: Uses the patient’s own healthy stem cells, collected before high-dose chemotherapy or radiation. This approach reduces the risk of immune rejection but may carry a risk of cancer relapse.
  • Allogeneic Transplant: Uses stem cells from a donor whose genetic makeup closely matches the patient. This method can offer a stronger immune effect against cancer cells but has higher risks of graft-versus-host disease (GVHD).
  • Haploidentical Transplant: Uses partially matched donor cells, often from a family member. This option expands donor availability and is increasingly successful due to advancements in transplant techniques.
  • Umbilical Cord Blood Transplant: Involves the use of stem cells collected from umbilical cord blood. These cells are less mature, lowering the risk of GVHD but may require a longer recovery period due to slower engraftment.

Bone Marrow Transplant Procedure

  1. Pre-transplant Conditioning: High-dose chemotherapy and/or radiation therapy to destroy cancer cells and suppress the immune system.
  2. Stem Cell Infusion: Healthy stem cells are infused into the bloodstream, similar to a blood transfusion.
  3. Engraftment and Recovery: Stem cells migrate to the bone marrow and begin producing new blood cells, typically within 2–4 weeks.
  4. Post-transplant Care: Regular monitoring for infections, GVHD, and organ function is essential during recovery.

Surgical Procedures in Blood Cancer Treatment

While surgery is not a primary treatment for blood cancers, it may be used in specific cases to manage complications. For instance:

  • Splenectomy: Surgical removal of the spleen when it becomes enlarged due to leukemia or lymphoma.
  • Lymph Node Biopsy/Removal: To diagnose or remove cancerous lymph nodes in lymphoma.
  • Tumor Resection: Rarely, solid tumors associated with lymphomas may require surgical removal.

 

FAQs about Blood Cancer Treatment

Can blood cancer be cured?

  • Some types can be cured, while others can be managed effectively with treatment.

What is the success rate of treatments?

  • Varies by type and stage; advancements in treatment have significantly improved survival rates.

Are there any natural remedies?

  • No proven natural cures, but supportive therapies like nutrition and mindfulness can help improve well-being alongside medical treatment.
