These results have been disappointing, and other modalities have been tried—including high-dose cytarabine regimens, 2'-deoxycoformycin (pentostatin), and anti-CD52 monoclonal antibodies (alemtuzumab). 19 In an HSGDTCL study, 2 of 21 patients treated with platinum/cytarabine-based induction regimens were still in remission at 42 and 52 months. 17 Another study examined a variety of induction regimens used to treat HSGDTCL in 15 patients. 18 Responses tended to be more durable in patients who received a dose-intense Hyper-CVIDDoxil regimen (fractionated cyclophosphamide, liposomal doxorubicin, vincristine, dexamethasone) alternated with methotrexate and cytarabine. Complete response was 50%, and median duration of complete response was 8 months. Over the past 10 years, a few case reports have described successful treatment with autologous or allogeneic stem cell transplantation. 20
Conclusion
The present case represents a unique HSGDTCL presentation. To the authors’ knowledge, this is the first report of HSGDTCL presenting with acute disseminated intravascular coagulation and AIHA with both cold and warm antibodies.
Hepatosplenic GDTCL is a rare, novel disease. To understand more about this pathology, investigators need to better characterize the disease process and the manifestations. The hope is that more information will contribute to the development of more effective therapies. The unique presentation reported here may help in further characterizing and understanding this uncommon disease.
