Non-Hodgkin lymphoma (NHL) is a type of cancer that affects the lymphatic system, an important part of the immune system. If you or a loved one is diagnosed with NHL, understanding treatment options and the journey ahead can help ease concerns.
What is Non-Hodgkin Lymphoma?
Non-Hodgkin lymphoma is a group of blood cancers that develop in the lymphocytes, a type of white blood cell responsible for fighting infections. NHL differs from Hodgkin lymphoma based on the specific cell type involved. There are various subtypes of NHL, which can be broadly classified as either aggressive (fast-growing) or indolent (slow-growing). The type of lymphoma and its stage at diagnosis play a significant role in determining treatment options.
The exact cause of NHL is not well understood. However, several risk factors may contribute, including age, a weakened immune system, certain infections (like HIV or Epstein-Barr virus), and exposure to certain chemicals. While having risk factors increases the likelihood of developing NHL, it does not guarantee a diagnosis, and many people with risk factors may never develop it.
Diagnosis: What to Expect
If NHL is suspected, a comprehensive diagnostic process will typically begin with a physical examination, including checking for swollen lymph nodes. The main diagnostic tool for confirming NHL is a biopsy, where a sample of the lymph node or tissue is removed for examination. Depending on the results, doctors may also conduct imaging tests like CT scans, PET scans, or MRIs to assess the extent of the disease and to stage the cancer.
Blood tests may also be used to help evaluate the function of the immune system and other organs. Once these tests are completed, doctors will determine the stage of the lymphoma. NHL is generally staged from I to IV, with higher stages indicating more widespread disease.
The staging process is crucial because it informs the treatment plan. However, it’s important to understand that staging is not necessarily a predictor of prognosis. People with higher-stage NHL can still respond well to treatment depending on individual factors, including overall health and the specific lymphoma subtype.
Treatment Options for Non-Hodgkin Lymphoma
There are multiple treatment strategies available for NHL, and the choice of therapy depends on several factors like the subtype, stage, patient age, and overall health. Here’s a breakdown of some of the most commonly considered treatment options:
Chemotherapy
Chemotherapy remains one of the primary treatment approaches for NHL. It involves using drugs to kill rapidly dividing cancer cells. The drugs can be administered orally or through intravenous injections. Chemotherapy is often given in cycles to allow the body time to recover between treatments.
While chemotherapy can be effective in treating many types of NHL, side effects may occur. These side effects can range from mild to severe and may include nausea, fatigue, and an increased risk of infection. Most of these side effects are temporary, but discussing potential risks with a healthcare team can help patients prepare.
Radiation Therapy
Radiation therapy involves targeting cancer cells with high-energy rays to shrink tumors or eliminate remaining lymphoma cells after chemotherapy. This treatment is often localized, meaning it is directed at a specific area of the body where the lymphoma is concentrated.
Radiation is more commonly used in early-stage or localized forms of NHL, but it may also be used in combination with chemotherapy. While radiation therapy can be effective, side effects such as fatigue and skin irritation are possible, though they vary from patient to patient.
Immunotherapy
Immunotherapy has emerged as a promising treatment option for certain types of NHL. This therapy harnesses the power of the immune system to identify and attack cancer cells. One form of immunotherapy is monoclonal antibodies, which are engineered proteins that target specific markers on the surface of lymphoma cells.
One widely used monoclonal antibody is rituximab, which is effective against certain B-cell lymphomas. Immunotherapy generally has fewer side effects than traditional chemotherapy, though it can still cause symptoms such as fever, fatigue, or allergic reactions in some cases.
Targeted Therapy
Targeted therapy focuses on specific molecular changes that drive cancer growth. Unlike chemotherapy, which affects both healthy and cancerous cells, targeted therapies aim to block the growth of cancer cells while sparing normal cells.
These therapies are often used in patients with specific genetic markers or mutations that make them more likely to respond to targeted treatments. Although this is a rapidly evolving area of cancer care, not every patient is eligible for these treatments, so it’s essential to discuss with a healthcare provider whether targeted therapy is appropriate.
Stem Cell Transplant
In cases where NHL does not respond to first-line treatments or relapses after remission, a stem cell transplant may be considered. This procedure involves replacing damaged or destroyed bone marrow with healthy stem cells, which can help the body regenerate a healthy immune system.
Stem cell transplants are complex and involve significant preparation, including high-dose chemotherapy to destroy the existing bone marrow before the transplant. Recovery from this treatment can be lengthy and requires careful monitoring. While it offers hope for some, it is generally reserved for more severe cases of NHL or those that have not responded to other treatments.
