Hodgkin lymphoma is a malignant disease of the lymphatic system in which lymph nodes and other organs are affected. It is one of the most curable cancers in children, especially when detected early and treated appropriately. Hodgkin lymphoma most commonly occurs in adolescents and young adults but can also affect younger children.
Treatment of Hodgkin lymphoma in children requires a multidisciplinary approach and usually involves a combination of chemotherapy and radiotherapy. Modern treatment protocols have significantly improved survival rates and allow most children to achieve long-term remission.
Main treatment methods for pediatric Hodgkin lymphoma in Belarus
- Chemotherapy. This is the main treatment modality for Hodgkin lymphoma in children. Chemotherapy destroys cancer cells and prevents their growth. Depending on the stage of the disease, combinations of several chemotherapeutic agents are used. Treatment is administered in cycles with recovery intervals. The number of cycles depends on disease stage and treatment response. Possible side effects include nausea, hair loss, fatigue, increased susceptibility to infections, and reduced appetite.
- Radiotherapy. Radiotherapy is used after chemotherapy to eliminate residual cancer cells in affected lymph nodes. Radiation is precisely targeted to minimize exposure to healthy tissues. In very young children, radiotherapy is avoided whenever possible due to the risk of long-term effects such as impaired growth and development. Modern radiation techniques allow highly accurate tumor targeting, reducing damage to surrounding tissues.
- Targeted therapy and immunotherapy. In complex or relapsed cases, newer treatments such as monoclonal antibodies or immune checkpoint inhibitors may be used. These therapies help the immune system recognize and destroy cancer cells.
- Stem cell transplantation. This option is considered in cases of relapse or when the lymphoma does not respond to standard treatment. Autologous or allogeneic stem cell transplantation helps restore bone marrow function after high-dose chemotherapy.
- Autologous transplantation. Stem cells are collected from the patient, cryopreserved, and reinfused after intensive chemotherapy.
- Allogeneic transplantation. Stem cells are obtained from a compatible donor when required.
Stages of Hodgkin lymphoma treatment
- Diagnosis and staging. Before treatment begins, a comprehensive evaluation is performed, including lymph node biopsy, blood tests, PET-CT, MRI, and other investigations. Disease stage (I–IV) determines treatment intensity and duration.
- Chemotherapy. Treatment typically starts with chemotherapy cycles aimed at achieving remission, defined as the absence of detectable cancer.
- Radiotherapy. Applied after chemotherapy depending on disease stage and response. In pediatric patients, radiation doses are kept as low as possible.
- Supportive care. Includes infection management, control of side effects, and nutritional support.
Long-term effects and follow-up
- Post-treatment follow-up. After completion of therapy, regular medical follow-up is required to monitor for relapse and identify potential long-term complications. Follow-up visits may include physical examinations, blood tests, and imaging studies.
- Cardiac and pulmonary effects. Certain chemotherapy agents and radiotherapy can affect the heart and lungs. Regular screening allows early detection and management.
- Growth and developmental issues. Children who receive radiotherapy may experience growth, developmental, or hormonal disturbances. Endocrinologists play an important role in long-term care.
- Psychological and emotional support. Treatment can be emotionally challenging for children and their families. Psychological counseling, peer support, and family-centered care are essential components of recovery.
Treatment of pediatric Hodgkin lymphoma generally yields very favorable outcomes, particularly with early diagnosis and a comprehensive treatment approach. Chemotherapy, radiotherapy, and newer therapies such as immunotherapy have significantly improved cure rates. Long-term follow-up, rehabilitation, and family support are crucial for helping children overcome treatment-related challenges and return to a normal quality of life after recovery.
