BACKGROUND Hepatosplenic T-cell lymphoma(HSTCL)is a rare subtype of non-Hodgkin’s lymphoma,which has an aggressive clinical course and an extremely poor prognosis.Chidamide is a novel,orally active,benzamide-type histone deacetylase(HDAC)inhibitor that has been used for peripheral T-cell lymphoma(PTCL)treatment.However,to date,there has been no report of the treatment and effect of the HDAC inhibitor chidamide in HSTCL,which is a special subtype of PTCL.CASE SUMMARY A 45-year-old male patient was admitted with splenomegaly and slight bicytopenia.He was diagnosed with HSTCL via splenectomy.The patient was treated with fractionated cyclophosphamide,vincristine,doxorubicin,and dexamethasone alternating with high-dose methotrexate and cytarabine regiment as inductive therapy.Unfortunately,the disease progressed rapidly during chemotherapy before a suitable allogeneic gene transplant donor was found.The chidamide-combined chemotherapy regimen and single-drug oral maintenance regimen achieved complete remission,duration of response of 9 mo,and overall survival of 15 mo.CONCLUSION The novel agent chidamide can be used in HSTCL to achieve deep remission and improve the duration of response and overall survival.
