摘要
BACKGROUND Angioimmunoblastic T-cell lymphoma(AITL), a unique subtype of peripheral Tcell lymphoma, has relatively poor outcomes. High-dose chemotherapy with autologous stem cell transplantation(ASCT) can achieve complete remission and improve outcomes. Unfortunately, subsequent T-cell lymphoma-triggered hemophagocytic lymphohistiocytosis(HLH) has a worse prognosis than B-cell lymphoma-triggered HLH.CASE SUMMARY We here report a 50-year-old woman with AITL who achieved a favorable outcome after developing HLH 2 mo after receiving high-dose chemotherapy/ASCT. The patient was initially admitted to our hospital because of multiple enlarged lymph nodes. The final pathologic diagnosis, made on biopsy of a left axillary lymph node was AITL(Stage Ⅳ, Group A). Four cycles of the following chemotherapy regimen were administered: Cyclophosphamide 1.3 g, doxorubicin 86 mg, and vincristine 2 mg on day 1;prednisone 100 mg on days 1-5;and lenalidomide 25 mg on days 1-14. The interval between each cycle was 21 d. The patient received a conditioning regimen(busulfan, cyclophosphamide, and etoposide) followed by peripheral blood stem cell infusion. Unfortunately, she developed sustained fever and a low platelet count 17 d after ACST, leading to a diagnosis of HLH after ASCT. During treatment, she experienced thrombocytopenia and Pneumocystis carinii pneumonia. The patient was successfully treated with etoposide and glucocorticoids.CONCLUSION It is possible that development of HLH is related to immune reconstitution after ASCT.
