The patient was hospitalized with enlarged inguinal lymph nodes, and pathological examination revealed that the lymphoma had transformed into diffuse large B-cell lymphoma. After two cycles of brentuximab vedotin in combination with rituximab, cyclophosphamide, doxorubicin, and prednisone (BV-R-CHP) chemotherapy, the patient achieved complete remission. This treatment was followed by autologous hematopoietic stem cell transplantation and lenalidomide maintenance therapy. At the last follow-up, the patient had been in continuous remission for 24 months. This case study suggests that the utilization of BV and R-CHP in conjunction can result in rapid remission, and it can be followed by autologous hematopoietic stem cell transplantation and maintenance therapy with lenalidomide. This treatment approach exhibits potential as a viable option for older individuals with transformed lymphoma.
