Long-Term Complete Remission of a Patient With Double-Hit Diffuse Large B-Cell Lymphoma Treated by Chemoimmunotherapy and Chinese Herbal Medicine

Double-hit diffuse large B-cell lymphoma (DHL) is an uncommon subtype of lymphoma which poorly responds to current drug therapies and has low rates of long-term survival in the patients. Herein, we report a case of a 73-year-old Caucasian male who was diagnosed with DHL with double-hit mutations of rearrangement of both c-MYC and BCL2 in November 2013. He commenced the standard R-CHOP-14 chemotherapy (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone) but changed to dose-adjusted DA-EPOCH-R protocol (etoposide, doxorubicin, vincristine, cyclophosphamide, prednisone, and rituximab) in the second and third cycles due to double-hit mutation. Because of intolerance to the intensive therapy, the patient decided to switch to Chinese medicine intervention. From March 2014 to December 2019, he was prescribed with a classical Chinese herbal formula-Sijunzi Decoction plus Prunella vulgaris based prescriptions. After 2 months of the Chinese herbal medicine intervention, the patient felt his right groin mass disappeared. Imaging follow-up showed no residual masses, and no lymphadenopathy was seen. During the period of Chinese herbal medicine treatment, his adherence and tolerability were well maintained with no adverse events. Imaging surveillances afterward found no evidence of lymphoma recurrence. His regular blood tests indicated that the patient's blood counts were normal and stable; no hematologic toxicity, hepatoxicity, or nephrotoxicity associated with Chinese herbal medicine were found. Follow-up visits until 2020 found that he had been living and enjoying a good quality of life for over 8 years post-diagnosis. This case study illustrates the potential values of Chinese herbal medicine in DHL treatment, alongside chemo-immunotherapy, and in maintaining long-term survival and satisfactory quality of life for DHL patients. The case report provides clinicians with preliminary evidence of the use of Chinese herbal medicine as a therapeutic strategy in the management of DHL.
