Successful treatment of refractory enteropathy-associated T-cell lymphoma using high-dose chemotherapy and autologous stem cell transplantation.

A 65-year-old woman presented with a 6-month history of abdominal pain and watery diarrhea. Type II enteropathy-associated T-cell lymphoma (EATL) was diagnosed based on the clinical presentation and pathological examination of the tumor. The patient received combination chemotherapy but did not achieve remission. Subsequently, high-dose therapy (HDT) and autologous stem cell transplantation (ASCT) were performed. After these therapies, she achieved complete remission, which has been sustained for 18 months. Although the role of HDT-ASCT for EATL is still controversial, the clinical course of this patient suggests that ASCT can improve the prognosis in some patients with EATL.
