Non-Hodgkin lymphoma (NHL) is a group of malignant diseases of the lymphatic system in which the tumor develops from lymphocytes (white blood cells). In children, non-Hodgkin lymphoma is characterized by rapid growth but also shows high sensitivity to treatment. Unlike Hodgkin lymphoma, non-Hodgkin lymphoma is less common in children and more often involves lymph nodes, bone marrow, and other organs.
Treatment of non-Hodgkin lymphoma in children requires intensive therapy, which most often includes chemotherapy and, in selected cases, radiation therapy and stem cell transplantation. Modern treatment approaches provide high cure rates, especially when the disease is diagnosed early.
Main types of non-Hodgkin lymphoma in children
- Lymphoblastic lymphoma. Resembles acute lymphoblastic leukemia (ALL) and often involves the thymus and other mediastinal lymph nodes.
- Burkitt lymphoma. A highly aggressive form of lymphoma that commonly arises in the abdominal cavity and may also involve the jaw and central nervous system. Requires intensive chemotherapy.
- Diffuse large B-cell lymphoma (DLBCL). May occur in various parts of the body, including lymph nodes, skin, bones, and internal organs. Treatment depends on localization and stage.
- Anaplastic large cell lymphoma (ALCL). An aggressive lymphoma that can affect lymph nodes as well as internal organs.
Main treatment methods for non-Hodgkin lymphoma in Belarus
Chemotherapy
- Chemotherapy is the main treatment modality for pediatric NHL. It destroys malignant cells and prevents their proliferation. Drugs may be administered intravenously, orally, or intrathecally (into the cerebrospinal fluid) to prevent or treat central nervous system involvement.
- The combination of chemotherapeutic agents depends on the lymphoma subtype and disease stage. Treatment is delivered in cycles with recovery periods in between.
Radiation therapy
- Radiation therapy is used infrequently, as pediatric non-Hodgkin lymphoma is usually highly responsive to chemotherapy. However, it may be applied in selected cases, such as residual tumors after chemotherapy or central nervous system involvement.
Stem cell transplantation
- Stem cell transplantation is considered in cases of relapse or refractory disease. High-dose chemotherapy eradicates bone marrow cells, including malignant ones, followed by infusion of stem cells to restore hematopoiesis.
- Transplantation may be autologous (using the patientβs own stem cells) or allogeneic (using donor stem cells).
Immunotherapy and targeted therapy
- In selected cases, newer treatment approaches such as monoclonal antibodies and immune checkpoint inhibitors may be used to enhance the immune systemβs ability to recognize and destroy cancer cells.
Stages of treatment for non-Hodgkin lymphoma
- Diagnosis and staging. Before treatment begins, comprehensive evaluation is performed, including lymph node biopsy, blood tests, PET-CT, MRI, and bone marrow aspiration. This allows accurate determination of lymphoma type and stage.
- Induction of remission. Intensive chemotherapy is initiated immediately after diagnosis to eliminate the majority of malignant cells. The goal is to achieve remission, defined as the absence of detectable disease.
- Consolidation therapy. Additional chemotherapy is administered after remission to eradicate residual malignant cells and reduce the risk of relapse.
- Maintenance therapy. In some cases, prolonged low-intensity chemotherapy is used over several months to prevent disease recurrence.
Long-term follow-up
- Regular medical follow-up. After completion of treatment, the child requires ongoing monitoring to detect relapse or late complications. Follow-up visits may include physical examinations, blood tests, and imaging studies.
- Vaccination. After therapy, the immune system may require revaccination. This is essential for protection against infections.
- Educational support. Prolonged treatment can affect learning and development. School counselors and individualized educational programs help children reintegrate into the educational system.
Factors influencing favorable treatment outcomes
- Type and stage of lymphoma. Certain NHL subtypes, such as Burkitt lymphoma, require very intensive treatment but are also highly curable. Prognosis is better with early diagnosis and prompt therapy.
- Age and overall health of the child. Younger age and good general health are associated with improved outcomes.
- Response to treatment. A rapid and complete response to chemotherapy is linked to better long-term survival.
Treatment of non-Hodgkin lymphoma in children requires an intensive, well-coordinated approach that includes chemotherapy and, in selected cases, radiation therapy or stem cell transplantation. With modern treatment protocols, survival rates are high, and most children can be cured and go on to lead full and active lives. Family support, psychological care, and long-term medical follow-up are essential components of successful treatment and recovery.
