Objective This study was performed to examine the treatment regimen used for an elderly patient with diffuse large B-cell lymphoma (DLBCL) complicated with renal dysfunction. Case report An 85-year-old man presented with nasal and sinus disorders in May 2018. He was also found to have renal insufficiency caused by long-term consumption of compound aminopyrine phenacetin tablets. Physical examination revealed irritation of the nasal mucous membrane on the right side and dark red nasal passages with a smooth surface. The right side of the neck contained several small peanut-sized lymph nodes. A biopsy of the right nasal neoplasm revealed germinal center type DLBCL. The mini–rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone regimen (mini-R-CHOP) was administered as the main chemotherapy regimen. Additionally, the use of thrombopoietin prevented further deterioration in renal function. This individualized treatment program helped the patient to achieve complete remission. The creatinine level decreased and was well maintained. Conclusion The mini-R-CHOP and rituximab cross-use regimen was found to be safe in an elderly patient with chronic renal insufficiency. Thrombopoietin exerted a protective effect on renal function.
