Abstract

Objective: To investigate the long-term clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with human herpes virus 8 (HHV8)-positive multicentric Castleman's disease (MCD). Methods: A 17-year-old female patient was admitted to Henan Provincial People's Hospital with the complaint of febrile for half a month, headache, and enlarged superficial lymph nodes on October 5, 2010. HHV8-positive mixed cellular Castleman's disease was found by pathological diagnosis of lymph nodes biopsy. After the administration of CHOP and Hyper-CVAD-B, the patient was still febrile, we administrated the followed COAP, two courses of VAD(Vincristine, Adriamycin, Dexamethasone), the patient received CR. Six months after CR, the patient relapsed, we administrated VAD and two courses of bortezomide+dexamethasone chemotherapy, and then the patient received PR. After that, the patient underwent allo-HSCT from his human leukocyte antigen (HLA)-matched unrelated donor after conditioning with Bu/Cy+Etoposide+Smoustin.graft-vs-host disease (GVHD) prophylaxis, which consisted of ATG (7.5 mg/kg, qd, ivdrip) from d-5 to d-2, cyclosporine (3 mg/kg/d, qd, ivdrip, for 24 h) started from day-1, MMF(0.5 g, tid, po.) started from day+1 to +28, and MTX (15 mg per time, ivdrip, d+1, +4, +7, +11). She received 3.5×10 6 /L CD34 + cells and 8.1×10 8 /LMNC. Results: Granulocyte engraftment occurred on day+12, platelet engrafted on day+14. Bone marrow biopsy showed normalization of trilineage hematopoiesis on day+33, chimerism: 97.6%. The transplantation was successful and followed up for 7 years with CR. Conclusion: Allo-HSCT might cure patients with refractory/relapsed HHV8+ MCD.
