Multiple Elective Surgeries and Cord Blood Transplantation for Multi-refractory Monomorphic Epitheliotropic Intestinal T-cell Lymphoma.

A 42-year-old woman was diagnosed with monomorphic epithelial-type intestinal T-cell lymphoma (MEITL) following small bowel endoscopy. The patient subsequently underwent a small bowel resection to prevent perforation. Bowel lesions progressed shortly after completion of first-line chemotherapy. Although four different salvage regimens were attempted, they were refractory, and both bowel and ovarian lesions progressed. Partial jejunal resection was performed during the fifth salvage regimen, followed by oophorectomy. After achieving complete remission, she underwent cord blood transplantation and remained alive 37 months after the diagnosis. Integration of elective surgery and allogeneic transplantation may be a treatment option for relapsed or refractory MEITL.
