Mixed cellularity Hodgkin lymphoma (MCHL), classified under ICD-10 code C81.25, is a subtype of Hodgkin lymphoma characterized by a diverse mix of cell types within the tumor. This specific code indicates that the lymphoma is located in the lymph nodes of the inguinal region and lower limb. The treatment approaches for MCHL typically involve a combination of chemotherapy, radiation therapy, and, in some cases, stem cell transplantation. Below is a detailed overview of the standard treatment modalities for this condition.

Treatment Approaches for Mixed Cellularity Hodgkin Lymphoma

1. Chemotherapy

Chemotherapy is the cornerstone of treatment for Hodgkin lymphoma, including mixed cellularity subtype. The most commonly used regimens include:

• ABVD Regimen: This is the standard chemotherapy regimen for early-stage and advanced-stage Hodgkin lymphoma. It consists of:
• Adriamycin (Doxorubicin)
• Bleomycin
• Vinblastine
• Dacarbazine

The ABVD regimen is typically administered in cycles, with the total number of cycles depending on the stage of the disease and the patient's response to treatment. For early-stage disease, 4-6 cycles may be sufficient, while advanced stages may require more cycles[1].

• BEACOPP Regimen: For patients with advanced disease or those at high risk of treatment failure, the BEACOPP regimen may be considered. This regimen includes:
• Bleomycin
• Etoposide
• Doxorubicin
• Cyclophosphamide
• Oncovin (Vincristine)
• Procarbazine
• Prednisone

BEACOPP is more intensive and may be associated with a higher risk of side effects, but it can be more effective in certain high-risk populations[2].

2. Radiation Therapy

Radiation therapy is often used in conjunction with chemotherapy, especially for localized disease. It can be particularly effective in treating lymph nodes in the inguinal region and lower limb. The use of radiation therapy may vary based on the stage of the disease:

• Early-Stage Disease: Patients with early-stage MCHL may receive involved-field radiation therapy (IFRT) after completing chemotherapy to eliminate any remaining cancer cells in the targeted lymph nodes[3].

• Advanced-Stage Disease: In advanced cases, radiation may be used selectively, often reserved for areas with residual disease after chemotherapy[4].

3. Stem Cell Transplantation

For patients who experience relapse or have refractory disease, autologous stem cell transplantation (ASCT) may be considered. This approach involves harvesting the patient's own stem cells, administering high-dose chemotherapy to eradicate the lymphoma, and then reinfusing the stem cells to restore bone marrow function. ASCT is typically reserved for patients with advanced disease or those who have not responded adequately to initial treatments[5].

4. Targeted Therapy and Immunotherapy

Recent advancements in treatment have introduced targeted therapies and immunotherapies, which may be used in specific cases:

• Brentuximab Vedotin (Adcetris): This is an antibody-drug conjugate that targets CD30, a protein expressed on the surface of Hodgkin lymphoma cells. It is often used for patients with relapsed or refractory disease[6].

• Checkpoint Inhibitors: Drugs such as nivolumab and pembrolizumab, which are PD-1 inhibitors, have shown promise in treating relapsed or refractory Hodgkin lymphoma and may be considered in certain cases[7].

Conclusion

The treatment of mixed cellularity Hodgkin lymphoma, particularly in the inguinal region and lower limb, typically involves a combination of chemotherapy, radiation therapy, and potentially stem cell transplantation for advanced cases. The choice of treatment is influenced by various factors, including the stage of the disease, the patient's overall health, and the presence of any high-risk features. Ongoing research continues to explore new therapies and combinations to improve outcomes for patients with this condition. For personalized treatment plans, consultation with a hematologist or oncologist specializing in lymphoma is essential.
