Effective Treatment Options for Non-Hodgkin Lymphoma

Non-Hodgkin lymphoma (NHL) is a type of cancer that originates in the lymphatic system.

The staging of NHL helps doctors determine the extent of the disease’s spread and is based on the Lugano classification system, which modernizes the older Ann Arbor system. NHL is classified into stages I through IV, each indicating a different level of severity.

• Stage I: Lymphoma is confined to one lymph node or a single lymphoid organ, such as the tonsils.
• Stage II: Lymphoma affects two or more lymph node groups on the same side of the diaphragm or one lymph node group with involvement of a nearby organ.
• Stage III: Lymphoma is found on both sides of the diaphragm or involves the spleen along with the lymph nodes above the diaphragm.
• Stage IV: The lymphoma has spread extensively to at least one organ outside the lymphatic system, such as the liver, bone marrow, or lungs.

Treatment Methods for Non-Hodgkin Lymphoma

The treatment strategy for NHL is tailored according to the stage of the disease and the patient’s overall health. The main methods of treatment include chemotherapy, radiation therapy, stem cell transplants, and medications.

1. Chemotherapy

Chemotherapy is a widespread treatment for various cancers, including NHL. It involves the use of one or more chemotherapeutic agents to target and kill rapidly dividing cancer cells. Chemotherapy can be used with curative intent, to control symptoms, or to extend the patient’s life.

2. Radiation Therapy

Radiation therapy (RT) uses high-energy ionizing radiation to destroy cancerous cells. It is often employed for localized cases of lymphoma or as part of an adjuvant therapy plan. Radiation is commonly used to shrink tumors before surgery or to prevent recurrence following surgical tumor removal. It is often combined with chemotherapy for enhanced effectiveness.

3. Stem Cell Transplant

Stem cell transplantation is increasingly used to treat both cancer and non-cancer-related blood disorders. It involves the use of stem cells—undifferentiated cells capable of becoming various cell types—to help regenerate healthy blood cells after chemotherapy. Two main types of stem cell transplants are used in NHL treatment:

• Autologous Stem Cell Transplant (AUTO):In this procedure, a patient’s own stem cells are collected, stored, and then reintroduced after high-dose chemotherapy to help restore healthy blood cells.
• Allogenic Stem Cell Transplant (ALLO): In this case, stem cells are donated from another person. The donor and recipient must have compatible HLA (Human Leukocyte Antigen) profiles to increase the success of the transplant. There are two main types of ALLO transplants—Ablative (using high doses of chemotherapy) and Reduced Intensity (using lower doses of chemotherapy).

4. Medications

Medication plays an important role in managing NHL. Some of the main drugs used include:

• Chemotherapy Drugs: These drugs are effective in attacking and killing cells that are growing or multiplying rapidly.
• Bone Marrow Stimulants:These drugs stimulate the bone marrow to produce new blood cells, which is especially helpful in cases where chemotherapy has affected the marrow’s function.
• Steroids:Steroids are often used to reduce inflammation, enhance tissue repair, and modify hormonal responses to support other treatments.

Each of these treatments may be used alone or in combination, depending on the specific needs of the patient and the characteristics of the lymphoma. Advances in treatment protocols are continually being researched, offering hope for improved outcomes in the fight against Non-Hodgkin lymphoma.
